< I had forgotten that I have a pile of VT 320s, will they work? ANY vtXXX. A VT320 is ok too. It only has to be RS232 or 20ms interface and not blockmode. Most of the latter terminals only do rs232/rs423 and 20ma was TTY or DECwriters. < Sounds like just picking up old software is a waste of time and money. <It's to be exactly right for the system that it's going on. Pretty much the case back then or you had to know it was hackable. < I wondered about using the drives out of an old Osborne model OCC 1 th <I have. They may work muost just pull the 360k drives from an XT. < You're right. I have manuals for NS* CPM, CPM assembler, CPM <interface, etc. I haven't had time to read all this stuff yet. I'm gla <you told me that CPM will run on an 8080. I've seen some very old CPM <stuff but I didn't think I could use it. But there is a chance. It was never a question. I've been running CPM for 21 years and also have a NS* horizon thats now 20 years old. < Actually now that I know what I'm looking for, my NS* CPM manual says <16K of Ram with an origin of 2000 Hex. I have a bunch of NS* manuals, I V2.x and later it had to be 20k so that is v1.4 (likely from lifeboat associates). <like to find the NS* software that goes with them. BTW the NS* CPM book <says that the NS* board is supposed to have a PROM on it that contains th <IPL. I did say it had a minimal boot. Allison
