[Coco] Schematic for external PIA, cart protoboard.

[Kip Koon]

Hi Chris,

I apologize for not having gotten back to working on the Coco Prototyping Pak.  One question I need a consensus on.  

Originally I laid out the PCB with a wide VCC and Ground trace on the far and near sides of the PCB like in the pdf below.  Click link to download.  Now I’m wondering if it would be wise to put the power rails all the way around the PCB.  Here is a dropbox link to a pdf of the PCB layout.  What do you guys think?  https://www.dropbox.com/s/0736lzhlvs7w1of/Coco%20Cartridge%20Prototyping%20Pak%20brd.pdf?dl=0

Hello,

 

Does anyone have a schematic for hooking up a 3rd PIA to the coco? Im looking for something I can get simple hi&low input/output via peek/poke from in basic on a CC2. 

 

Also there was some talk a few months back of a cartage proto-board. Did anything ever come of this? 

 

 

Thanks!

 

Chris
