PDP-11 configurations (was Re: PDP 11/44)

Jerome Fine replies: While I started with a BA23, there were too few slots for the development system that I wanted. So I shifted to a BA123 with 12 slots with room for 5 full height drives. Originally, I used RD53 drives, but when a number of 600 MB ESDI Hitachi drives became available, I shifted to using 3 * 600 MB with the first drive used as the development drive and the second and third drive as exact backups. By the way, as most of you know, I run only RT-11. And there are SIX terminals stacked on my rather large desk, one VT220 and 5 VT100s. I use all six terminals, one connected to the background job and the others connected to system jobs, specifically the KED editor so that I can see as many screens as possible of the same file files or multiple files in READ ONLY mode while: (a) I make modifications to a source file (b) Run the code in a newly modified source file which needs debugging. Since the RT-11 debugging program freezes every other job (which means that the other KED editing sessions are also frozen, I at least have a number of screens to enable me to check the code being tested. So while I agree that multiple terminal are probably rare with RT-11, I have almost always been involved with applications which use large number of terminals, usually with a SYSGENed version of RT-11 with multi-terminal support included.
