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
that was the first one. It was a marvelous tool for system
development. Seemed like magic at the time.

Fairly typical system (they came with 16k but you really needed 64k to
do anything with language compilers under ISIS-II).

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 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 suspect that most of them are going to be in the same situation. I'll
keep looking. Take care.
