For what purpose? And if so, is there any need to write such software that only works with 8255 or 6523, but not both? Btw it would be a good idea to once and for all agreee on a way to read a specific address in the firmware rom to determine if the card has a 6523 or an 8255. (This of course applies to the 8088 board. I see no reason for making the Z80 board with a 6523 at all, thus there is no reason for differentiation of any software. Btw I assume the idea from Commodore were that the built in Kernal code for talking with the 8088 card should work with the Z80 card too. There might be a need for 6509 software to determine if it's a Z80 or an 8088 card in the machine though. I wounder how or even if Commodore ment that to work? Does the 6509 software start the coprocessor and first talk to it via the 6526/6523 interface and get some ID thing from the coprocessor to determine if the 6509 software fits the installed card? -- (\_/) Copy the bunny to your mails to help (O.o) him achieve world domination.
