Somewhere around here I think I have a prototype board but I have no idea where it is. I pulled some of the card and it has a 8Mhz 68K with 16K of RAM. I am looking for the manuals but I have doubts on that. It definitely has 1M of ram. The CIM-2 has 2 6850's and 2 6821 (header is there but no cable). The 2 hard drives in it are ST506 interface.
There are 2 backplanes, one is triple row (male on the card, female on the backplane). The other is 2 row (male on the card, female on the backplane) and connected to the triple via an I/O board. I can't recall if one is a VME bus, or Euro Bus or STE Bus.
I definitely want this up and running as it's a good example of an industrial micro- computer before the IBM PC became popular. I know it runs OS9 as that's what I had on it and the ROMs also say so. :-) Microware's OS-9 for the 68K became OSK which later became OSK. Microware OS-9 still exists and supports a large number of processors including the one for the Raspberry Pi.
Yup, definitely very interesting hardware. I'll have to keep my eyes open for that stuff. I have no experience with OS-9, but have taken an interest in it over the past few months. I'm slowly putting together a 6809-based system to run it on. -Dave -- Dave McGuire, AK4HZ New Kensington, PA
