John,
I can assure you that they run well and behave well after you get them
going.
I have 3 operational units. Well at least the last time I had them up along
with the computing keyboard. It was sort of a programmable calculating
counter in a box.
I can see why they were very amazing way back then. They also have a really
good oven I have 8 of those. That oven and then the counter started me into
time-nuttery about 1990. Because what on earth would have used this oven?
They are heavy and suck power "green?" Not. But a nice display.
One of them did indeed loose the display and I rebuilt the display with
yellow orange LEDs and while I was at it added a serial rs232 function out.
The system communicates with the display at about 1 Mb/s as I recall.
I can also tell you that at least on one of the counters it ran me around
for months hunting for the issue.
Over the years I obtained the manuals with the secret interpolator
schematics and programmers references etc.
Regards
Paul
