This Web page last updated May 14 2020. Background: I obtained a PDP-8/A system s/n AG13076 in Sept 2019. I examined it, but only tested the Programmer's Panel in my earlier acquired PDP-8/A. This page is just a stub, I'll fill it in as work and time permits.
To email me, see see my ordering Web page for my email addresses.
See my other DEC minicomputers as listed on my DEC Web page.
The 8/A arrived in a large box, reasonably packed but dented. The damage was entirely mechanical - a tribute to DEC's industrial chassis! - and repaired. All electronics appeared intact. This looked like it was pulled from an industrial controller.
Removing the Programmer's Panel revealed the interior as shown.
As of last edit of this Web page, I've not tested this PDP-8/A system.
Rather than try to bring up the whole 8/A system, I chose to test the Programmers Panel and the DEC 8K core, on my other 8/A system. I'd not operated the prior 8/A in some time, but it seemed to come up and function reasonably well, without running programs or a serial console. When I stablized the power supply from use (starting up with a Variac), I then tested the complete Programmer's Panel from the newly-acquired 8/A. The Panel functioned fine. I also tested, another 8/A Programmer's panel I acquired prior - it too ran OK.
