In addition to modern stuff I found, I picked up an Intel SDK-86
trainer - it has screwposts for +5VDC, -12VDC and GND, an unremarkable
8086, several peripheral chips, 8 x D2142 RAMs, 8 x MAN71A 7-segment
LED displays and a pristine prototyping area. Since I have stack of
+5VDC -> -12VDC DC-DC converters (from Qbus COMBOARDs), I was planning
on attaching one to this board so I can run it off of +5VDC only.
Now to find docs...
