Earlier there was a question about MSCP disk sizes. I did some checking.
RSTS understands all the devices known by name in SIMH, including the "giant"
RF73. As of the "big disk" support, which is in V10.1 and I think a few earlier
versions, it can handle something that big. It draws the line at 4096 MB; bigger than
that and it will tell you the disk is too big when you try to initialize it. I thought it
might use only the part it can handle, but no, it simply refuses entirely.

I hate to think what setting up a 4GB drive would look like. I have a 1GB SCSI HD for my
PDP-11/73 (assuming the drive isn’t dead). I still remember just how long it took the
RSTS/E 10.1 install to prepare that drive (so long I only did a single pass on the drive
test).
On a related note, Paul, do you have any idea if RSTS/E can be installed from a CD-ROM?
I’ve done installs of RT-11 and RSX-11M+ from CD, but couldn’t figure out how to do a
RSTS/E install from CD. I can’t remember if I was able to use 4mm DAT, or if I had to use
a TK50 (it’s been a *LONG* time since I did any installs).
