By the way, I was looking for text and BASIC tokens, and I don't see any. There's actually very little non-asm data at all in the ROM, after tracing the initial JMP table and the IRQ handler at 97b6. At 9069, right after the jump table, is this: https://i.imgur.com/w3cEKmR.png Given the angle brackets with 2 spaces after them, it might be some sort of prompt or display. The code at 9db8 loads 0937/8 with 9069, and I think that's the only reference. No clue what the $1b is used for, though. There's only 1 "xxx #$1b" at 9df0, and it doesn't seem related. At 9512 is a bit table: 80 40 20 10 08 04 02 01 9cc6 has a potential block/line drawing character table, as mentioned: https://i.imgur.com/Y58YktM.png It's used to compare against 03da in a long chain of tests starting at 99d5 The most curious is at 9d58, which does seem to be some sort of printout routine with X and Y: https://i.imgur.com/FXIUaDx.png The only reference to those addresses seem to be the lda/ldx uses above, so this might be able to be a useful starting point. And the most entertaining is the end of the image, where there's some leftover source code text: https://i.imgur.com/4RO5G48.png :) Beyond that, there's no other data or text in the ROM image, unfortunately. It's all code. [I don't know if the list supports attached images, or handles Unicode for the PETSCII conversions, so I just pasted screenshots] Message was sent through the cbm-hackers mailing listReceived on 2017-09-05 15:00:03
