im looking for some detailed explination or pinouts of the chips found on the sega genesis.
i have a model one genesis
1991 171-5963 10
ic bd m5 usa
i have some information but nothing that detailed or that accurate. i found a file rumored to be a sega techincal manual named segadoc.zip, sega2.doc...but i cant seem to view the file.
if anyone has any detailed information on the following chips id be gratefull
the two sega custom chips
315-531A-01
315-5433
and the Z80 clone
NEC D780C-1
i tried to find some sort of documentation for the D780C-1 on NEC's website but had no luck.
i was also wondering if anyone knows what the unused port labeled, CN4, is/was or planned to be used for. i noticed that on some genesis's there is an actual 9pin controler like port in place.
thanks in advance .
nevermind i found what i was looking for...
