The
Memory-3.1 Board |
The
Memory-3.1 Board uses two Generic Array Logic devices (GAL's)
to significantly reduce the chip count. |
|
IC2 is a
GAL22V10D |
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
