As many retrocomputing enthusiasts, we also collect vintage computers and parts, luckily got 2 Intel MCS-85 evboards, often referred as "SDK-85", one is working, the other is untested. Our goal is to develop a custom rom image for the rom bank 1 which is empty now. Planned to get some 8755 writable rom chip for this purpose, but couldn't find any kind of firmware around. Felt motivated, modified and rewritten a mastermind game (uses bank 0!) delivered with Mamedev's MAME
In the past, got a scanned version of a 8355 rom chip content, namely the official intel monitor image source code. Due to obvious reasons, it was full of typos and errors - OCR cannot deal with zeros and letter "O" and so on. So after entered manually, found out that we ain't got no 8085 compilers :) So quickly wrote one in perl that even handles EQU directives and formulas needed by the source. Here you are:
Bet it is worth to mention that I've never had any Z80/8085 experience before when I wrote this assembler. It had only one (completed) job - successfully compiled the scanned and manually corrected source code! :)
To be continued!
Have fun!
