Intel MDS 225 (1st post)

Hi Tony, Dwight, Yes, that pretty much sums it up - I knew that one board was the disk controller (I think it is marked as such) and I'm pretty sure that one other board has the 8085 CPU on it as you describe. Interesting, that is the first explanation of the ISIS acronym I have heard so far. Not too much explanation required on that topic - I do a bit of firmware development here at work, with the Microchip PIC series of microcontrollers. Fortunately, the PIC ICE is nothing nearly as large, slow or heavy as the MDS system in question. The MDS was used to develop many of our products up until we went to PICs a number of years ago (and well before I joined the company). The MDS was given me by an engineer here, and came with a pile of disks and no documentation. I was hoping that I could get some useful OS running, CPM would be great; I have several CPM machines already, so it's not totally foreign to me. Would I need a different CPU card, or other hardware to run CP/M? For that matter, who ported the CPM to this architecture? I assume that the MDS architecture is totally weird & proprietary... Dwight, I will look through my set of disks for the program that you request, I have no idea what is in there, other than the softs to run the ICE function. Thanks to both of you for your help, much appreciated.
