[sci.electronics] "Sega Genesis Chip List"

ccastsp@prism.gatech.EDU (Stacy Purcell) (12/01/89)

   Here's a list of the main ICs in the Sega Genesis.  I wasn't sure
which numbers were relevant so I just wrote most of them down.  

   Does anyone have a clue as to what the SEGA chips do?

Has anyone figured out how to interface the Genesis?  There's a big juicy
connector on the side which looks _very_ interesting, but I have no idea
what to do with it.  Also, what is that 9-pin-din on the back for?  I
plugged a monitor cable into it, when I didn't realize that the RGB came out
of the ROUND din, and it did some really nasty things.  It would be nice if
we didn't have to buy that $100 1200 modem, but we could use an existing
modem that we already own as a replacement for the TeleGenesis.
