Re: WTB/WTT: Intel MDS-800
I have a few Intellec MDS Series II development systems. They can host an ICE-85. I’d sell you one. They are VERY heavy. I’m in Michigan.

It has the more unusual cable that was meant for the Series II that was meant to upgrade the internal disk drive from single density to double density. See the unused edge connector? It has the sticker that came with that upgrade kit that says internal drive upgraded to double density on the front of the chassis. The Intel two-board set is in the photo just below the ICE boards. It is dark but you can see there are two boards because of the board ejectors. Follow the cable off one of those boards and it goes to that unused edge connector. On another topic, not in this system, there WAS a third party controller that emulated the Intel board set and required no BIOS modification. Zendex was the manufacturer. I never used one but it sounded interesting. It was only one board.

It was a bit of work. I seem to remember thinking it was written to run on an IBM mainframe, if that makes sense. But they got it working and we used it until Intel came out with their 8080-based development systems. Then we started using them to compile. Dave
