Looking forward to seeing more. I wanted to let you know I revived another board using the PROM socket to Serial board. This is a great tool and I have developed the code for searching for any onboard ram. This board is a Multibus Z80 with 8K Prom and 56K dynamic ram that I got for $22 from ebay. No schematics, (and no onboard serial port) but realizing the prom must be at 0 to boot, the ram search code was placed there and Showed 56K ram and where it was addressed. Then I ported your SBC-85 confidence code, with the driver I wrote to use the prom adapter for serial i/o (CI/CO routines) and your confidence code now has another home on the board. I am looking to revive another multibus 4 port serial card using the Signetics SCN2651 serial interface and plan on the confidence code using this board for serial i/o. This is a great tool for reviving these boards. Thank you again for making this available!!! I really should be building another prom socket board.as I have another std bus board to revive. As you can see, I have added the board to my toolkit for working on legacy hardware and will continue to use it. Hope you are well.
