Subj : IMS Series 8000 Microcomputer To : All From : Abbub Date : Thu Apr 25 2024 19:53:25 Using an IMS International Series 8000 computer to write this. The main ¨(master) CPU board and memory board (Z80 at 4MHz with 64k of RAM) was built in ¨1979. The two MPU (slave) boards also have Z80s and 64k of RAM, as well as two ¨serial ports. The operating system is TurboDOS, which is a multi-processor ¨version of CP/M (sort of) that allows the main CPU to share system resources ¨(hard drives, floppies, etc) among the MPU boards. The MPU boards have two ¨serial ports, one for connecting terminals to access the operating system, and ¨one that can be used for modems, printers,etc. I'm connected to one via a ¨terminal and then have the second one connected to TCPSER so I can telnet to ¨my BBS and send you guys this message. I have, for what it's worth, the second ¨terminal also up and running and am playing The Hitchhiker's Guide to the ¨Galaxy in the other window. Multi-tasking like it's 1979! ;) --- * Origin: Telnet: bbs.WalledCTTY.com:1989 - Fort Collins, CO USA (21:2/145) .
