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.
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.
Hello all,
Just wanted to ask if anyone out there has an Intel MDS (Microcomputer
Development System). That was the 8080-based system that Intel sold for
developers to develop hardware and software based on their
microcomptuers. It ran an operating system called ISIS-II from Intel.
Yes, I have one, and most of the manuals. The only manual I am missing (I
think) is the hardware reference for the ICE-80 in-circuit emulator for
the 8080 processor. I have the hardware (2 multibus cards + probe) for
that option.
My system contains (I think) :
8080 CPU
4 off 16K RAM cards
Fairly typical system (they came with 16k but you really needed 64k to
do anything with language compilers under ISIS-II).
Bootstrap/monitor/bus controller
I/O (for tty, paper tape, prom programmer, etc)
ICE-80
Double-density floppy controller + 2 drives
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.
Anyway, anyone who would like to discuss these
systems, I'm game. I
have an Intellec 800 and a Series II (the successor).
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 would be
interested in anyone who might have for sale a set of floppy
diskette controller boards for these systems. It is a two-board set and
I need the double density version.
I have the double density disk controller + all the manuals, but obviously
I want to keep it. --
