Some other comments: The Exormacs from Motorola never, as far as I knew, ever ran Unix. It predated the Unix bit. I don't know that the VME/10 ever ran Unix, either. The preferred OS on those machines was VERSAdos. I like VERSAdos, still use it occasionally. Powerful enough to be quite useful, and clunky enough to be interesting! Apparently, there is enough legacy in VERSAdos that a 3rd party has "inherited" the rights and still sells it as a Real-Time Operating System! The CPU in a CC-40 was not a 9900, but rather a TMS7000. Still an interesting processor from my favorite company, Texas Instruments! There were several makes to the 990 mini line, but I'm not familiar with it. Some used discrete logic, some used the 9900 processor chip for the CPU. The OS of choice was DX-10. -- ********************************************** * David Ormand *** Southwest 99ers * * dlormand(a)aztec.asu.edu *** Tucson, Arizona * **************************** TMS9900 Lives! *
