This directory contains the two PROM dumps made in May 2026 from my Morrow DiskJockey 2D-B Rev-2 S-100 FDC card.  

I had purchased this Morrow 8in disk system in 1981 to be used along with my S-100 expansion box for the Exidy Sorcerer.

- PROM # 3D is identical to those read by others in the past.

- However, to be expected, PROM # 8C is different for the Exidy Sorcerer since the monitor ROM is located at D000. This should be the first "official" reading and archiving of this PROM for the Sorcerer. 

To understand how the 256-vector encoding is performed, and to verify that everything is okay, I created the logic table in "6301, PROM 8C, Address Decoding Verification Table.pdf" to alieviate any concerns that I may have had. Everything checks out fine for the D000, E000 and F800 PROM dumps.
