Anyone familiar with these PCMs? I got a CMI 1640 and little help needed. Here's photos: https://drive.google.com/drive/folders/1w74AYe6lRSn9gJhyKVlBYAq5zRDWybSw?usp=sharing
What this 370 clone is exactly? If I have understood right, Steven Ippolito's IPL Systems Inc developed the original machine and CMI (Cambridge Memories Inc) made them. Also these sold as Omega/480 and Olivetti 5300 series. Later CMI made their own versions and I believe this one of those. But I haven't found model 1640. So is this 1641..? What is difference between CMI and others? Microcode? I got belong with the machine a couple manuals, Maintenance and Theory of Operation. Unfortunately original microcode disk is missing (and 8" drive...), so that would be needed if I ever want to fire this thing up. Any ideas where I could find a one? All ideas & info are welcome! - Johannes Thelen johannesthe...@gmail.com Finland Before microcomputers blog (Finnish) http://ennenmikrotietokoneita.blogspot.fi/
