Booting MS-DOS, CP/M and RSTS/E* on a DEC Rainbow!

I have a problem. I’m all out of space in the room for CRTs, but I don’t have a single machine in the room that can boot DOS or CP/M. Almost every CRT in the room is dedicated to either a unique system or lives life as a data terminal. So, it’s time to start consolidating. And in this, DEC has got my back. The Rainbow 100 is an epic little triple-use machine that can boot MS-DOS and CP/M as well as work as a VT-100 terminal. This thing is really, really cool! *: I fully realize that in the title I say, “Booting MS-DOS, CP/M and RSTS/E,” but the Rainbow 100 is incapable of booting RSTS. In this case RSTS is being booted by the PDP-11/83 and the Rainbow is being used as a VT-100 terminal. But that was all a bit too long to write in the title. However, if you’re still upset about the title, write “I read the description, and I’m still pissed!“ and I’ll get a good chuckle and actually read your comment.
