I am looking for CP/M Plus or dpc/OS disks for a late S-100 computer made by Action Computer Enterprise, Inc. (ACE) called the Discovery 500 Multiprocessor. My research uncovered a few ads in Byte from late 1983/early 1984 that may not previously have been posted to the web: http://vintagecomputer.net/ace/ACEDiscovery500Ads.pdf The hard drive is toast, so I need an OS/system build disk, or manuals to try to re-construct a CP/M BIOS. Here are some pictures/info I collected: http://vintagecomputer.net/browse_thread.cfm?id=230 Thanks Bill
