Here is a schematic of the CreatiVision Cartridge Pinout...
Thanks go to Mobsie and Madrigal!
Greetings TOM :0)

V2: I updated the schematic and filled in the missing pins...
Also Information regarding differences to CreatiVision MKII.

V3: Small update, Info about internal 74LS139 added

Great! Very useful!

Schematic updated and added description to missing pins...

Also some Info on how the MKII works to switch to an external CPU (i think was intended for the ColecoVision adapter).

Thats Great, now we have all. Thank you.
Pin 30 give me New Idea.

Small update...

I wondered how the addressbus is disconnected from the 6502 when in "external CPU" mode, as i found nothing to do this...

But then i figured it out: The Addressbus is simply not used anymore! Because the Colecovision Expansion will have its own Addressbus and only uses the TMS 9929 and its 16kb ram (and the HF Modulator), which does not require an addressbus...

Pin 30 is perfect for integrate a SID 6581 like the c-64. It will be easy to integrate one SID to my I/O interface i work on.

Yeah, I wish more computers had a external input like that. You could easily make a speech synthesis cart too or a sampling circuit or whatever. I'd like to make a cart with an analog moog filter and route the sound from the creativision into the cart

Hi,

The Audio Input Pin simply gets an Audiosignal form the Cartridgepin and puts it to the TV Speaker / Video out...
Nothing can be done (in the CV) with this Signal... Also this is only an Input i think? (but i may be wrong as it may be mixed with the CV Sound,- after looking in the schematic - now i think it actually is mixed, but would be a bit less in volume because of going thru 2 "3K3" resistors...) must test with a game...
