<A while ago, I mentioned that I had a DECMate III, the one without <the hard drive. It has two DECWrite manuals, a disk set for the same, <Could anyone tell me what OS I can use on this, where I can get it, <and how to install it. The DEC is not at my house, and any mistake will DECMATE-III is a sorta PDP-8 using the harris 6120 chip that is a microprocessor clone of the basic PDP-8 with some added features. With some notable exceptions it will run most PDP-8 software and there are some spcific DECMATE modified veriosn out there like OS/8 and operating system. FYI DECMATEs nominally run WPS a word processing, list management, spread sheet and communications terminal emulation package unique to them. If you can surf the web most of the software for PDP-8 and DECmates are out there along with tech info. To get the OS on the decmate there are two paths... get someone to make a copy of the OS/8 disk set(its permitted) or down load the files from those sites and use PUTR ot teledisk(disk cloner) and a 1.2m 5.25" drive on a PC.
