Ok, a PDP-8 question. Which version used the Harris
IML6100 processor?
My first bench job was fixing Transaction II compatable
charge card machines based on this processor. I was told
that it was the PDP-8 proc, all 12 multiplexed bus bits
of it. Cmos processor, no bus drivers, driving straigt
into the edge card connector. Spent a lot of time cleaning
edge connectors. So much that I had to "re-plate" them with
the soldering iron when the copper started to show through
too much. But that was a VERY long time ago!
