Setting up a PC Trasporter on a IIGS

[micheledipaola]

Awesome possum! Now I can start cross checking stuff.

My color switch card does nothing when connected, so I just threw a few bucks at it and replac d these parts... Let's see.

Bought the same chips with the same intent of replacing them on a (seemingly) non-working ColorSwitch... but then never found the time to do it - let us all know if something changes!

Anyway I guess the new ColorSwitch pcb project could be a place to look at, for finding some answers, even related to the pinout we're all trying to figure out; for instance your question:

Also, does Ground need to get connected to each of the various grounds at the DB15, or is one sufficient? (Pin1+Pin6+Pin13)

have been bugging me for a couple years already as I am scared to fry / mess up something with wrong connections, being a total noob with electronics.
