Speaking of Eprom Programmers - I have a Pro-Log with the 1702A module.
What I do not have is the manual for the 1702 module...Does anyone have
a copy? I have a copy of the schematics thanks to another member here -
but the module has a switch to set Vdd at either -9 (1702A?) or -10V
(1702 only?). My module works fine, but just like to have complete docs.
Hi John
The 1702 used a different algorithm than the 1702A did and the pulse
widths were different. The switch is most likely to select between
1702As and 4702As. The 4702A used -10V to match the 4004. I doubt
the programmer was intended for 1702s.
