Never knew there was one of those.
Indeed. I think I have the 2708, 2716 and 8748 (!) personality boards. I
have the 2 24 pin sockets on the front (alas - the 16 and 24 pin pair
would probably have been more useful).
The personality boards contain the 4001 ROMs containing the programming
code for the particular EPROM.
That was another one of those boards prone to failure. Too much analog
stuff I suppose. Tough to keep it in cal.
Indeed it was. It says Intellec 8 on the front, but I seem to recall that
MCS8i is written on it somewhere. I think mine was built as an 8080 system
(The date codes on the CPU board are not much later than those on all the
other boards, for example), rather than being upgraded.
Indeed you did! Altairs are everywhere! You have the machine that
likely the Altair was designed with!!!

I have the ICE-80 as well, and used it many times
(in the way past!).
Intel was the first company to have in-circuit emulators (I believe) and
I'd _love_ an ICE-3000 (or whatever it's called) - the one for the
3000-series bit-slice chips. Do you happen to have any manuals on the ICE-80? I got
all the other
manuals for my system, but those, and the ICE-80 probe were missing. The
probe turned up in a clearout 2 years later (!), but the manuals were
never found.
I'll check. Might just have them.
UPP (Universal Prom Programmer) controlled by a 4040.
Now the UPP is a unique device. It has personality boards for many different type of memories. There aren't too
many eprom programmers out
than can do 1702s, but it is one.
I don't have the 1702 personality board, but then my MCS8i can do 1702's,
so it's no real problem... Mine's the MDS800. I also have the MCS8i, which
was also 8080 based, used
a custom bus, and had a full front panel. That one has 8K of RAM, (2 4K
cards), 2K ROM (in 1702s), 8080 CPU, I/O card, and 1702 programmer.
I think the MCS8i was originally the Intellec 8. It was 8008 based, but there was an upgrade that made it an 8080 cpu.
As old as I am, that one
predates my experience. The Intellec 800 was my first development
system.
I bought my MCS8i at a radio rally (hamfest). It was a choice between that
and an Altair. I personally think I bought the more interesting machine...
