For those interested in playing with Jim's emulator, a few resources: Bitsavers has some doco and bits:
http://bitsavers.org/pdf/prime/ http://bitsavers.org/bits/Prime/ I have been assembling what I hope will be the definitive Prime info site. It's not complete, but contains manuals scanned by, among others, AEK and Jim Wilcoxson, as well as material from my Prime-using past, etc. I have more documentation and software to add as I have time. https://sysovl.info/reference_prime.html Of particular use might be this writeup on installing PRIMOS Revs 22 or 23 on the emulator. It's set up for the old demo version of the emulator, so needs a fair amount of updating, but may help get you started. I'll work on it soonish. https://sysovl.info/reference_prime_drb_installing_primos.html De
