The Dual 6850-2 Board

The Dual 6850 Board uses two Generic Array Logic devices (GAL's) to significantly reduce the chip count.
 
IC2 is a GAL16V8D
IC4 is a GAL16V8D
 
These parts are electrically erasable programmable logic devices.
 
The very popular and inexpensive TL866A MiniPro Programmer was used here to program the above parts. Before attempting to program the GAL's with a TL866A check the following ...
 
App Software Ver: 6.85
Firmware Ver: 03.2.86
 
... and upgrade if necessary before proceeding.
