IMSAI Support

IMSAI PDS-IIParastream is very proud to support IMSAI products. Parastream’s founder used to work for IMSAI between 1978 and 1979, so this is a personal endeavor for him.

We are in the process of gathering the best information available on every IMSAI product. From the menu below, you may find all the information we have on the products we support so far. Each page typically includes an overview, how to set it up in a system, errata from IMSAI, how to modify it to work with today’s IEEE 696 standard, exciting new upgrades you can perform, parts, schematics, and other resources.

We have compiled a comprehensive list of IMSAI products and how they make use of all 100 pins of the bus. You may find it to be as useful as it has been for us. IMSAI Product S-100 Bus Signal Usage.pdf
