I've often entertained the same fantasy.  iRMX was extremely advanced for its time.  In fact, I think some of its features are advanced even by today's standards.

I had at least one working system that was put into storage.  Hopefully I'll get time before long to see if it still works.

Wow, Yea this brings back some found memories of my early career.
We used the Intel Multibus to build our product line. All of our Imsai 8080 code
was ported to run the on 8085 slave cards and iRMX86 running on a
master 8086 card. One card cage running independent OS and CPU's
communicating on a common bus. First cloud computer? Sorta.

Image where we would be today if IBM would have selected iRMX for
the OS rather than PC DOS.

I've always wanted to build one of the Intel multi-bus systems but there's just
not that much out there.

Looked a while back Joe, did not see one.   The multibus and S100 have a lot in common.    I have been looking for a 80486 multibus board schematic but found none.  Would really help me in doing a S100 of the same.

 

Good luck.

Hi All,

 

As most know, I am in the process of building n S-100 machine as well as an Xi-8088 box. These two projects are my main focus, and I will be working on them until both are complete. However, I am also very interested in the Intel Multibus, and already have two processor boards, the Intel 80/05 (an 8085 unit) and an 88/25 (an 8088 unit).

 

Does anyone know of an active group for the Multibus computer system like this group for S-100 systems? I feel that this group is one of the  best computer groups on the Web, and have searched for something similar to the S-100 for the Multibus, but without success. After I finish the Xi and at least one S-100 system, I want to start a Multibus machine. Any suggestions will be greatly appreciated.

 

Thank you in advance for any ideas!

 

Best,

 

Joe
