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).

I didn't have any issues installing 10.1 from Exabyte 8mm tape drives
attached to CMD TMSCP SCSI controllers. I never tried 4mm DAT.

True, though of course you can tell it to skip the pattern test, and then you can also
tell it to skip the erase pass. If you do this then the initialize is quite fast.
