In the old days you had the CP/M cartridges for the Commodore 64. Too make a long story short, this inspired to create a 80188 cartridge that you stick in the expansion port of the C64. And I need a BIOS for it. I'm very familiar with the 8088, including programming it, But I am completely unfamiliar with the 80188, or better, its differences with the 8088. For example, it has those programmable pins at pin 25..32 and I would like to know how to program them.
I have the Intel datasheet, found good info on RetroBrew and I found the Intel's Programmers Reference Manual.
But any good info, pointers and source code is welcome!
