Ebay item 272914490265
This is a ModComp IIC I think. It's all broken up in parts and half
assembled.
I don't think new it was barely $18,000 though, but some day, maybe the
seller will give up and put up a realistic price. Who knows what's in it
exactly but generally it looks like a communications model with a 7 or 9
track tape unit. The point of ModComp was to build custom systems but if
the info on this system does not exist on BitSavers, let me know and I will
scan some docs. I have info on the part numbers from the photos.
The ModComp docs talk about IBM system emulation vs. DEC, so think along
those lines more so, this is *not* a DataGeneral / DEC me-too despite
looking a little like a PDP 8i

That's an incredibly bad set of pictures.
I can't tell if it is really disassembled or if they just did not
photograph it in any meaningful way.
It looks like there are at least 3 cabinets. Main CPU, standalone disk
drive, tape drive. I wonder if there was a card reader or any other
peripherals.
The boards look like they pull out from the system chassis horizontally,
rather than vertically like my ModComp does. That just seems weird - as it
would be impossible to separate the accordion style board assembly in that
orientation. Again, maybe just really bad photography.
The slanted console of the first photo makes me think this suffered a
serious drop at some point.
There is a lot of corrosion on the boards.

Well, that was ~$64K today, so you can't really compare. I don't see to
many of them, so it might win price points for rarity.

The tty controller board makes me want to agree there.

I have a full doc set for our ModComp II, but many of the things are
different, so YMMV.

The system gave me the impression it was built up with transistors. Any
possibility of that?? I don't know the history of the Modcomps to
speculate, but that might put it out of the range of what Al's put up on
the Modcomps.? The ones I knew of dated to being TTL level gate chips,
rather than component, like the 8s or straight 8, and some logic in the 8I
Unless the guy thinks there is someone with a hardon for that Modcomp,
and there may well be, it is an incredibly bad listing for an asking
price of $18,000.? And by doing that, rather than a ridiculous reserve,
people who might buy will stay away, defeating the purpose of such a
listing to gather interested buyers, and take up with them around ebay.
the 8/I I bought was listed very high, but I eventually got the system
for a reasonable price, including having it delivered by the seller,
which is how such an exercise should work.
thanks
