- Yeah! I'd sell one of Dave's kidneys to get one, too...> I've never heard of that (which surprises me, being both an S-100 and
>a PDP-8 guy), but I can tell you I'd sell a kidney for one!

At the time, there was a single-board computer build around one, plus at least 2 systems on the market. I'll peruse some old Byte, Kilobaud and Interface Age issues to see if I can locate an ad for this specific thing.Cory - WA3UVV
- The trick to putting the 6100 on an S-100 bus is that the 6100
(like the PDP8) wants a 12-bit data bus. OSI actually had 12
bits on their bus, but S-100 only has 8. Of course IEEE696

- I worked for (owned) a different company (Micro-Integration, Inc.) and we did some projects (not this one) with I.E. Systems. We bought the company (I.E.) in the mid '80's long after the PDP-8 board. What we did do together were boards and software for connecting microcomputers to IBM mainframes via 3270 coax and 5250 twinax. The first boards were S-100, and later they were for the IBM PC. The PC brand name was BlueLynx.
The PDP-8 S-100 board was in 1979-1981, before the IBM PC. I.E. Systems also did a ROM chip for the SuperBrain somewhere around 1981 that gave it special qualities (don't remember what).
I'm trying to get in touch with the guy who designed the PDP-8 board. I have a friend who may have his contact info. I'll get back to the group with more info when I get it.
