Hi there,
A longshot I'm sure - but I am wondering if anyone familiar with MSI (Midwest
Scentific - SS50 bus system) would happen to have a copy of the software for their 1702A
EPROM burner, I think the model is PR-1. I just picked one up and am eager to see if I
can use it to read/burn 1702As, something that has been an issue for me for a while now.
Reading them is pretty easy. BURNING them is crazy. They
need an 80 V power supply, and I think you XOR the address
or something as you apply the programming voltage.
