Oscilloscopes and related

I have a small stock of oscilloscopes, either rack mount or portable or desktop. We'll offer these at modest prices, but we will need to spend time and effort to pack them for proper shipping so that adds to shipping costs. We'll consider offers for pickup from central New Jersey to avoid those charges. As of Sept 2006 I'll offer a substantial discount for the 7300 and 7600 rack-mount units and their plugins, if you pick up from me in central New Jersey (USA).

Oscilloscope test probes

I have a limited number of oscilloscope test probes. They seem common enough on the Web auction sites, at low prices for 100MHz bandwidth or better. I see no point in buying them to resell, so I don't have any available.

Tektronix 7000 series scopes and plugins

We have several Tektronix 7000 series scopes with some 7000 series plugins. Speed or bandwidth depends both on the "mainframe" and the plug-ins which fit into the mainframe.

Tektronix 7313 60MHz or 76XX 100MHz rack-mount storage oscilloscopes.
Three bays for 7000 series plug ins (two vertical amplifiers, one horizontal sweep). 120/240V AC powered. Includes "readout system" support for alphanumeric display of settings from appropriate plug ins (typically voltage range and sweep time). Some units also have an adapter on the back which displays on-screen alphanumeric codes settable via thumbwheels. Check the Web for tech specs. We are not offering manuals at this time; Check the Web and hamfests.

As of Nov 2007 I have some 7000 series rack-mount oscilloscopes as follows below. Some work OK, some have minor faults, none are dead outright. I'm looking for ANY OFFERS for these, PLUS SHIPPING, shipping weight of 48 lbs will cause these to cost between $20-$40 to ship within the USA.The units I have are 7313, 7633, 7623A, only a few of each.

Tektronix 7000 series plug ins, tested and NOT WORKING, some with simple faults, some dead. All eight available for $40 plus shipping as of Nov 2007.

Tektronix type 82 dual trace plugin for Tektronix 500 series oscilloscopes. Untested, pulled from oscilloscope, looks clean and undamaged. You make offer. this is old, vacuum tube technology, but still in use by many techs.

Heath and Heathkit instruments

Some Heathkit and Heath manuals are on our Heath and Zenith Web page

Heathkit EUW-19A (see image) Operational Amplifier System. Malmstadt-Enke type, from the Malmstadt & Enke's book "Electronics for Scientists" which describes this EUW series of Heath products. The book shows the EUW-19 model; the "A" version is slightly different, see this image of the front panel. (An actual manual, or copy of one, would be of interest to me.) Five vacuum tube operational amplifiers from the 1970's, for the analog lab! Very retro product for the late vacuum tube era - that's right, 12AX7 op amps! There are EIGHT 12AX7s in this unit, among others as seen in this photo. All tubes are "Mullard" brand. Amps spec'ed for gain flat to about 100KHz. Cosmetics fair to good. Interior photos show some surface rust but components look good in general. Obtained March 2006. Will not test, as given age chances are you'll need to check all the paper "condensers" and so forth. Value of this item in the few hundreds of dollars, as it's an ANALOG COMPUTER which is of collectable interest. Let me know what you'll pay for this: we'll determine shipping and packing.

heathkit IP-2717A or IP-2717 High Voltage supply. two voltage adjustable supply. Follow this link for a typical photo of this item. 0-400V DC at 100mA, 0-125V (negative) at 1ma. Two panel meters, current and voltage. Also 6.3V and 12.6V AC outputs. Typically I get these in good cosmetic condition, some scuffs and dents. However, often the voltage controls (potentiometers) are damaged and so adjustment is erratic, so they need to be replaced, see repair notes below. Shipping weight 19 lbs packed.HCheck below to see if I have any available.

Heathkit IP-2717A HIGH VOLTAGE supply None available as of 2006.

Heathkit IP-2717 HIGH VOLTAGE supply, like IP-2717A but older model with more vacuum tubes, different design. One available, nonworking, no top cover, no meters - otherwise looks intact. Sold AS IS for parts only. $35 plus shipping.

Heathkit IP-32 HIGH VOLTAGE 0-100 volts at 1MA and 0-400 volts at 100mA. Voltage and current meters switchable to either supply. Older than 2717 above. Units tested for good voltages under no load, ask for specifics. Also see notes below about replacement voltage controls (potentiometers). Starts at $59 plus shipping, depending on condition.

Heath IP-20 0-50V at 0-1.5A rated. One meter, switched between current and voltage reading. Cosmetics good. Will test upon request. $49 plus shipping.

Repair notes: I've had to repair the controls on a few of these Heath high-voltage power supplies: here's some notes from a client about them. Replacement pots can be bought from Radio Shack and other sources.- Herb.

I just opened up an SP-2717A.  The pot in this unit looks original, and it
is actually marked 50 k ohm "AUD".  So it appears this is just an audio
taper pot.  It measures a tad below 10% at 50% rotation.
 
The 500k B pot looks to be linear if I actually measure the pot.  But the
voltage output is well below 200 volts (closer to 100) at 50% rotation on
this unit.  (I had already adjusted the zero and 400 V trim pots before
doing this.)  I suspect this is just an artifact of how this circuit works.
 
I guess I can understand why they selected an audio-taper pot for the C
voltage adjustment.  This would provide greater resolution at low voltages.
Remember, in an audio (logarithmic) taper pot, turning the pot (let's say up
or CW) X degrees from any initial voltage will result in the same Y
percentage increase in voltage from the initial voltage.  The amount of
rotation to get from 10 volts to 11 volts should be the same as 50 volts to
55 volts, or 100 volts to 110 volts.

Any HP oscilloscopes and related accessories will be in my oscilloscope section.

lasers and optical

Wyatt Technology DAWN-FH Laser Photometer. Apparently a flow photometer, to characterize molecules by light scattering in liquid. Older model from mid-1980's, desktop, also known as "DAWN F". The test cell is behind the front, shown in the photo as a white circle of insulation. The HeNe? laser is shown in this photo from the uncovered top as the black cylinder behind the test cell. The rear panel has data and other connections. But the "channels" can be read manually from the front panel. Powers up, display shows "vapor alarm", I presume because the test cell is open to the atmosphere. The laser is operating, as this image shows, and various channels seem to respond. Selling AS-IS. Our descriptions are not guaranteed to be completely correct - you should consult the manufacturer or other experts for technical specs and details of use.

Pharmacia Ultrospec III model 60-2097-62, UV and Visible Spectrophotometer. Powers up, shows "cell" on display, so may need a removable turret of six cells. Ask for details. Should be worth a few hundred dollars. Has second halogen lamp, condition of lamp not known.

SpectraPhysics 3900S, very incomplete. We have the housing for the Spectra Physics 3900S laser, with a few optical mirrors, and not much else. Maybe the base was used as a small optical bench.

Huggins Laboratories INFRAscopemeter and sensor. Uses IR to measure temperature, seems to work OK but not calibrated. Ask for price.

Wollensak FASAX camera B-C43. High speed movie film camera. Not yet evaluated, obtained Nov 2006. Ask for status.

Phototec IV camera. High speed movie film camera. Not yet evaluated, obtained Nov 2006. Ask for status.

Paillard Bolex 16mm film camera. Movie film camera. Not yet evaluated, obtained Nov 2006. Ask for status.

Other instruments

Keithley 615 Digital Electrometer. Has 3-1/2 digit display (three digits plus 1/0). Measures coloumbs, amps, ohms. Measures extremely low values of current and extremely high values of resistance. No probes. Old, uses Nixie display. Power cord frayed, zero set button works but has some damage, but it appears functional, see photo measuring 1 Megohm resistor. Additional value in this instrument is in the Nixie tubes, which used have sold for several dollars EACH. Please, no offers below $50 plus shipping for this working instrument.

Keithley Model 147 Nanovolt Null Detector. As it says, is essentially a DC analog meter to zero-detect down to nanovolts. A meter is superior to a digital readout to monitor by eye. Switchable scales from millivolt to nanovolts. Has analog output for chart recorder. Can run from 6V 4A-H NiCad battery, needs replacment after 35 years! Meter dates from the 1970's. No probe included, needs a shielded cable which has minimal voltage or current-generating contacts - remember, this is very small voltage to measure! Meter powers up but can't check for operation. PDF of manual available and you can find it on Keithley Web site. We'd like $39 plus shipping for this.

Keithley model 417 picoammeter two units available. Not yet tested Nov 2006, ask for details.

Keithley model 602 electrometer. Not yet tested Nov 2006, ask for details.

Sinclair DM2 Multimeter, seems to work OK. With 110V/60Hz wall power supply. This could be a classic! Sold by Clive Sinclair's company (the ZX-80 Sinclair guy) in 1974, 1975 as a kit for 50 pounds (UK). What's it worth to you?

E-C Apparatus Corp EC-500, power supply. Still under evaluation, ask!

Photometrics A2S, apparently an AIA to SCSI converter or AIAI to SCSI. Has two SCSI connectors, looks like 50-pin SCSI-2, and a longer connector for AIA. Unit is 10" X 10" X 2 approx. Ask for details.

Eico 377 sine and square wave audio generator. Old, classic unit. 20Hz to 200kHz in four bands. Not working, dead, sold AS IS for $20 plus shipping.

General Radio 1217-B Unit Pulse Generator, less power supply (a seperate unit I DON'T HAVE model 1201-C 6.3 v AC 4A & 300v DC 70 MA). Not yet tested, but this unit is in good cosmetic condition. INternals look good, has six vacuum tubes. GR brand items seem popular so we're offering this unit. Let me know what you'll pay for one, plus shipping, as described.

General Radio 1203-B Power Supply attached to an unnamed GR power amplifier. Power supply may fit the 1271-B above, I don't know. The amplifier has a dial for gain, a pair of banana pins marked "600 ohm" for input, and a pair of banana pins marked "3 watts" for output. Units clean but untested, $20 plus shipping.

General Radio 1232-A tuned amplifier and Null detector. **SOLD** Battery powered filter, range within 20Hz to 200KHz. Log or linear analog meter display, multiturn tuning know and decade switch. Very small. A customer who bought the GR 1232-A had advice about upgrading the battery holder: contact me for details.

Optimation Inc RCD-4 sine wave oscillator. Apparently precision as it has four decade (0-9) controls to set frequency. Audio range. A/C powered.

Simpson 270 meter w/ 654 Audio Wattmeter adapter! 270 series 3 meter, not an old model, looks in good shape. With model 654 matching audio wattmeter adapter. This adapter apparently supports measurements at 8, 16 and 600 ohms impedance. There is a slide rule on the adapter to convert meter readings from volts to watts. $59 plus shipping for both.

Cases

Presto brand? equipment suitcases, 19" X 16" X 10", with locking latches and accordion folders. Like Parker brand. For transit or tranport or shipping of equipment and instruments. One or two five-slot folders for documents or boards. Hard molded plastic ribbed construction, room for padding. Weight with folders is 15 lbs. External dimensions (inches) are 19 X 16 X 10. Internal dimensions depending on ribs and with folders removed is 17-18 X 14.5 X 9. A few keys available, keys appear to be universal. Five cases available, $20 each plus shipping.

GPIB, IEEE-488, data collection, comm, development cards

I have a number of various PC cards (ISA, PCI, NuBus bus) for data acquisition or control. They are untested but look undamaged. If you have software or links to software I can try to test. I'm looking for reasonable offers for these; offers of $10 or so are not reasonable. If you want Apple or Mac NuBus cards, check my Mac Web site's NuBus section.

ISA prototype or proto board cards

These are cards for 8-bit or 16-bit (XT OR AT) ISA bus, which allow you to build your own card. Components are mounted on sockets or directly on the card. If you don't know what these are, you can't us 'em!

JDR brand 16-bit protoboard JDR-PRIO AT type 16-bit blank card with layout for decoding the ISA bus, using PAL and other logic chips. Three cards, new unused and sealed in baggies. $29 each.

Augat brand wirewrap protoboards 16-bit AT bus, long cards. Has ALL wirewrap pins. Two cards, unused, $49 each and worth every penny - these have hundreds of GOLD plated pins.

Other cards

Ultra-X brand "Examiner" 16-bit diagnostic card. This is an ISA or EISA card which displays lights for DMA and IRQ's, has a reset button, and a temperature alarm. I have no docs or software at this time but the company has been contacted (Jan 2008) and they still show the card on their Web site.

Scientific Solutions Stepper Motor Controller, 8-bit ISA card part number 20018. UNUSED cards in box, two cards available. Uses CY525 Stepper Motor chip, two chips per card. 1981 product. Copies of docs available as well. Card is about 12 inches long.

Imaging Technology series 151 image processor Not yet evaluated as of Nov 2006. A box which presumably has Multibus cards for image processing, with two large flatcables which presumably go to an interface card (card not available). Ask for details, let me know if YOU have more info.

Innovative Integration PC32, DSP card This card has a Texas Instruments TI TMS320C32 on a 16-bit ISA card for PC's. There are apparently A/D and D/A's on this card, and two DB-37 connectors male and female. The chips include TMS320C32PCM40, Analog Devices AD976 (4 chips). There is a JTAG 12-pin connector and a serial 12-pin connector. There is a large Euro-card like connector as well. Card is pulled from Pentium II PC.

Harco Industries Parallel / Interface 044-039-055. 8-bit ISA card with female DB-25 connector on end. Has two Li batteries, eight NEC D43256BCZ-70L RAM chips. 74LS244 and 74LS373 drivers and recievers to the parallel port. Also Dallas DS1210 and DS1211 chips. Maybe it's set up as an old parallel port card with battery backed memory! Maybe the Dallas chip is a clock chip! It's up to you to work the details.

Ariel PC-C25 or DSP-C25, ISA (old PC) cards. FOUR available. These are signal processing development cards for the Texas Instruments TI DSP chip, TMS320C25. One Web site referred to this card as a "1-ch 14-bit AIC". These are 16-bit ISA cards, very long length. Chip on card is TMS320C25FNL, with 40MHz crystal, four Toshiba TC55464P-25 program RAM, four CY7C195-25PC data RAM. Two boards have a socketed chip, TLC32040. Card has RCA in and out ports on back (end of PC); 50-pin flatcable "parallel I/O" connector.

These four Ariel cards are contained in a old AT&T 80386/25 WGS system, with Ariel development software on hard drive (and backed up to ZIP and CD and floppy). Contact me for details, but briefly there is a floppy's work of development system around a MS-DOS based C25 assembler and Turbo Pascal software interface.

In addition, I acquired seperately the following Ariel development software and manuals, on 11 diskettes (copied to a CD):

> PDS-320 Drivers & Installation, MSC Driver Disk 1
> PDS-320 Drivers, MFORTRAN, LFORTRAN, FORTRAN Disk 2
> PDS-320 Drivers, LC, BASIC, BASCOM Disk 3
> PDS-320 Drivers, QBASIC, PASCAL, TPASCAL, MASM Disk 4

> PC-C25 FFT Demo 3
> DSP-16/PC-C25 Diagnostics and Source 

Also contained in the above AT&T system is a Bit 3 501-101 card, ISA card. It has two ports on the end which appear to be fiber optic. Chips on board are AM7969-125DC and AM7968-125DC "TAXIchip" labled.

Iomega PC2B card with lables for PC2, PC2B50F DDXPC2F. This is apparently an old old SCSI card of some sort, may have been used with HP JetStore 2000 tape drives. Has external and internal 37-pin connectors. $20 plus shipping, condition unknown.

Allen Bradley 1784-KTX . 16-bit ISA card for communications with A-B products using DH +, DH Plus, and DH-485 networks. List price is over $700, used price seems to be $60-$80 as of Dec 2004. The A-B Web site suggests this card can be used for a 15% credit for an upgrade card or product. Demo drivers may be available from the Web at no charge, check the Web for specifics. Card removed from PC w/o hard drive or software, looks in good condition. But we have an original CD with "FIX 7.0" software from Intellution INc. (Now a division of General Electric GEfanuc) from 1999. FIX is a software package for industrial automation; support and drivers appear to be online. Looking for your offer.

IBM brand GPIB interface cards for IBM-PC's I have two 8-bit ISA cards (for IBM-XT's and later) made by IBM for the General Purpose Interface Bus (GPIB, HP-IB, IEEE-488), model 6541503. One is the card only, the other an unused old stock card in original box, with manuals, diagnositic diskette, and card in original antistatic bag. These are not tested so sold AS-IS. Shipping weight about 4 lbs. These are old but maybe you need exact replacements. For Linux software, you might check the "Linux Lab Project" on the Web. Apparently there is a current (2002) card, model AX5488, that is compatible with this card.

For Apple NuBus IEEE-488 controllers, check my Mac parts Web page. I may have other IEEE-488 devices for the Mac, check other parts of my Mac Web site accordingly.

IBM Data and control cards I have (Mar 2004) three IBM brand Data Acquisition and Control Adapters (DACA), card number 6323710 model number 6451502. No docs, not tested, found in a collection of old stock cards so these are sold AS-IS in antistatic bags. Here's an image of the three cards. These are long XT-type (8 bit ISA) cards, with some kind of long thin external connector. Two cards have a "loopback" block in this connector for testing. This is all we know specifically, a Web search shows these were an IBM product in the mid 1980's

Until recently there were no on-line docs or software that I could find. (If you have this info let me know.) But in November a client found a site which HAS ON LINE manuals and software, on this private site.

An on-line IBM research paper had the following information: "the DACA has two analog outputs with 12-bit resolution, four analog inputs, a digital output of 16 bits and a digital input of 16 bits. The analog input channels mulitplex into one A/D converter of 12-bit resolution; the rate of data sampling can be as high as 17kHz. The dynamic ranges of the analog inputs and outputs are switch selectable: from 0 to +10V, from -5V to +5V, and from -10V to +10V." This card was used with a distribution panel, essentially a cabled card with screw terminals. Another user of this card says it also has a 32-bit timer and a 16-bit externally-clocked timer/counter.

Looking for offers on these DACA cards, shipping weight 2 lbs for one card.

Daystar Digital cards with Z180 MPU. Two identical cards, look like MCA MicroChannel bus type, copyright 1988. Card has Zilog Z180 (one socketed), 12MHz crystal nearby, Zilog SCC chip, RAM, and some logic. Also a DB-9 connector (layout shows 2nd connector). I/O to DB9 appears to be AM26LS30 and AM26LS32 and some 280 ohm resistors. My guess: some kind of serial communications card, probably LocalTalk. If so the ADF is 6674 (whatever that means). Make offer, but it has value for the Z180 chip!

Data Translation DT2821-F-SE card. This is a used pull from a PC. A 16-bit AT or ISA card, 12-bit A/D 150KHz 16 channels; two D/A's 130KHz; 16 I/O digital lines; with interrupt and DMA capabilities. Not tested. Some info is on the Web from Data Translation, possibly drivers. Also some Linux drivers on the Web. Looking for a decent offer.

National Instruments PC-DIO-24 ISA card. Has flat cable male connector, 50 pin. 180712-01.

National Instruments PCI-MIO-16E-1 PCI I/O card with 6 single or 8 differential analog input channels (12-bit) with a maximum sample rate of 1.25 MHz, 2 analog output channels (12-bit), 8 digital input and output lines, and 2 counter/timers (24-bit) with a maximum source clock rate of 20 MHz. Note that National Instruments has renamed this board to PCI-6070E. Check the Web for more info.

DAS-1202 ISA card, 2 available. With DB-37 connector, also flatcable to another DB-37 connector. Has Harris CP82C55A chip, LSI custom chip. Digital/analog card.

PIO-24 ISA card. 8-bit bus. Parallel I/O card.

half of ATA (ISA bus) to VME bus adapter. ATADA card is 8-bit ISA card. Card says "ATADA Ver 2.1 pro_VME + ARW". Made by Weisz systemtechnik in 1999, there is product info on this Web site: http://www.wiener-d.com/fr-misc3.htm Let me know what this card is worth to you. I don't have the VME side card, the "ITVME 6 VME bus master".

HP 7090A Measurement Plotting System is a 6-pin desktop plotter with three analog input channels which are digitized at 33KHz for 3KHz storage and plotting. There is also a date/time clock to date stamp the plots, a LCD character display to show status, signals and setups; and an IEEE-488 (HP-IB, GPIB) control interface. They don't make plotters like this anymore! Here's an image of the plotter. Details of these features:

• DC to 3 kHz Bandwidth, 33.3 kHz Sampling Rate
• 3 Channels with simultaneous sampling
• 12-bit Resolution, 1 k Buffer/Channel
• 6 Trigger Modes with up to 100% Pre-Trigger Capture
• Full HP-IB Programmability and Data Transfer
• Annotation of Set-Up and Trigger Conditions and Data Points
• Floating and Guarded analog inputs.
• 6-pen turret

Small plotter fiber pens

I have dozens of new-old-stock plastic computer plotter fiber-tip pens. The link is to a photo of one, with a cap on the end. Staedtler model 32BG03-9 (black) and 32BG03-3 (blue), suitable for many old HP plotters. These are packaged by fives, and I have about 50 sets split roughly between black and blue. Looking for offers for lot or for several sets at a time..
