To email me, see see my ordering Web page for my email addresses.This document copyright Herbert R. Johnson 2021. Last updated NOv 13 2021. Jim Battle's SOL-20 Web site covers the Processor Technology "Sol" and provides a lot of resources
including an emulator, files, and manuals.
Additional Processor Tech information is in a document I edited from a comp.os.cpm discussion in 2004 on Persci 8-inch floppy drives. They were used in a Processor Tech product, and that discussion evolved into some Processor Tech
recollections. I also got a reply from Lee Felsenstein in August 2005 on the history of the company and of his activities with Proc Tech.
I've worked on a SOL computer in 2012.
Check the progress of my work on this restoration Web page.
Regarding the manuals below, I do not offer "sets" of manuals. I offer manuals individually or in some cases I'll identify sections of manuals available seperately.
By and large most companies created "sets" of docs from individual
manuals for cards and software. Also it's cheaper to YOU if you don't
buy docs for card or software you don't have anyway!
