Which layout exactly is needed? Could you describe it?
I believe it is divided into EVEN and ODD ROMs, but I do not know if that is bytes or words. I read somewhere that WinHex will work for this application in EVEN/ODD words.
I need to pull out the 1200 and 4000 schematics. I am curious if I can go larger. 512k in two ROMs is 256k, but I wonder if I can use 512k ROMs and build a 1MB ROM image, instead -- with the caveat that my CYberStorm will only MapROM up to 512k.
I am pretty stoked, though. I never bothered to build my own ROM, though I have wanted to. In my 4000 that is mostly irrelevant since I have a Deneb with the FlashROM loaded with stuff, but for my 1200, 2000, and 500+, I now have a more up-to-date ROM and may even be inspired to build a custom one to eliminate those annoying power-up reboots.
