My last S-100 I purchsaed before caving in to an IBM clone was the Morrow Decision I. I loved its ability to handle N* hard-sectored as well as soft-sectored 5" disks as well as 8" drives, and of course a huge 15 MB hard drive I had salvaged from my Horizon. Alas I sold it before moving back to the US from Canada. I now have a Decision I (with a more industrial metal case, locking key-switch plus built-in Fujitsu hard drive and more "sophisticated" MB) and Allison Parent was kind enough to get the switching PS going again for me, and I finally tried hooking it up to a Televideo terminal. There are 4 ports on the "MB" - 3 standard 25 pin D-connectors and 1 15 pin, all coming off the back of the MB. Upon booting, it sounds like the HD is loading, but I get no response, not even garbage, from any of the 3 25 pin connectors. (And I don't have a 15 pin connector right now to make an adapter, so chances are that the 15 pin connector is the 'master' serial port while the other three are for the multi-user Micronix which apparently this Decision I was set up for (I also found some hand-written labels on one of the boards referencing "M*nix") or are parallel ports. Anyway, this is not the Decision I that I had some familiarity with. Is there anyone out there who knows this machine who could help me get it up and running again? I have the docs for the Z80 CPU, the Disc Jockey DMA controller, the hard drive controller and the 256k memory card, but not for the 'advanced' MB (I don't know enough circuitry to figure out what the heck all the extra stuff is - obviously some serial ports or maybe a combination of serial and parallel). I don't even know at this point if this unit can be made to run plain vanilla CP/M (or preferably ZCPR) (I found some web references to Micronix having to "transfer" files from a CP/M disk over to Micronix before they could be used.) I don't even know if there are any specific "features" which would prevent me from running CP/M on this unit. I also have some Morrow 5" and 8" diskettes with CP/M and CBIOS files for various combinations of 5" and 8" configuartions off the the DJ DMA board. At this point ANYTHING anyone can tell me about the Micronix Decision I would be helpful. Thanks. Bob Stek Saver of Lost Sols (...and other stuff)
