Re: 65c816 in a IIc



Ah, what I meant by that is it takes one pin, but that presumes that
the rest of the needed support is present.

Otherwise.. you have an '802. Which I see they don't sell anymore. I
don't have the binder with the information in it handy right out
front, but pin #1 is coming to mind, that if you don't get it to work,
you can leave pin #1 out of the socket even, and that makes it work.
But the current crop of WDC parts are fine, as well as the CmdMicro
CPUs that the IIgs would have in many of them.

The pins missing from the 8 bit vs. 16 bit are BE, M/X, VPA, VDA, and
ABORT.

For example, the 816 option from both AE and Checkmate, they have a
couple GALs and a 245 on them, you bring the MMU on board and the CPU
of course, replaces the onboard //e one.

I crammed a ZipGSX into a //c board once, with the AE '816 card, later
on I discovered that I didn't even need that. I could have just used
the thing. Zippy, since it was ProDOS 8, even was able to set system
speed and slot speeds.
