[Coco] cartridge prototype board

[Bill Pierce]

There is also GIMEChip's (Little John) design of the 26-3024 & 26-3124 MPI clone. The plans were in maltedmedia but finding them now may be hard. I have a copy if needed. This design was never tested.
GIMIEChip had designs for several projects that should be looked into, including... 


8k Eprom board
32k Eprom board
512k upgrade w/256 cycle refresh
FlexiBuffer buffered port expander
FlexiMidi MidiPak
Orchestra90 clone
Tri-Cable
FDC Floppy Disk Controller
Satallite Board for 26-3124 MPI PAL Upgrade
Slot Extender
Stereo DAC Soundcard
Universal Color Composite Monitor Adapter


And I'm sure if you look around, you'll find more

Tom Gunnison's MPI clone plans are on several websites, including mine. He
also has some videos on YouTube of it in action.
