The prom boards have Intel 1702A eproms on them, but they are soldered in.
I am pretty sure the first is one of the processor cards from a PDP-8/e,
but I have no idea what the other boards are for.
The 1702As, as noted, are soldered in, which makes me think that
this was more than just a generic, burn-your-own-ROM card set.
Also, if the M8330 is surplus to me (I think I have quite a few base 8/e
card sets, save the bus load card), does anyone want it?

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!
