[Coco] 26-3124 M.P.I. Upgrade #2

[sales at gimechip.com]

I've just posted my method of using a 16v8 GAL chip to upgrade the 26-3124 M.P.I. to CoCo 3 compatibility here:

Normally, this is done with a 74LS10, a trace cut, and some jumper wires. My method DOES NOT require a trace cut and is 100% compatible with the Tandy Satellite Board Upgrade. The caveat? You have to program a 16v8.
