Ok, I am looking for the form factor of a box and an external terminal.
The box for the Decmate III looks like it's about 1.5'w x .5'tall x
2'deep or
somthing like that.
I would probably be using my PC Laptop as a terminal (1 to save space,2
to provide for
a "paper tape" (save to file, paste from file)
I suppose what I would want to know is what can I run RSTS from that
won't scare my wife, and
would look sort of like a PC (box only)
Also Whatever should be available enough to be cheap and easy to find.

I have an HP terminal I can use, or I can use my PC laptop with
it's
serial port. Whatever I start looking for it should support RSTS/E
What I am trying to find out is:
(a) If you don't count the terminal as part of the total system, then
does placing a 4 * 4 Qbus backplane and everything else needed
to run a PDP-11 inside a VT100 (which changes it into a VT103)
constitute a ZERO increase in size?
(b) If you do count the terminal as part of the total system, then
does the VT103 exceed the size of a (terminal / DECmate III)
system?
At this point, I suspect that the whole subject is similar to how
many angels can dance on the point of a pin, so it really does
not matter whether you choose (a) or (b). Myself, I prefer
(a) and conclude that a VT103 has a ZERO increase in size
over a VT100, so essentially the size of the PDP-11 system
is also ZERO - which is about as small as you will ever get.
And since I can probably find a 3 1/2" SCSI hard drive to
use with a SCSI host adapter instead of the 5 1/4" MFM
hard drive that I originally used, the hard disk can now be
many GigaBytes and the end of the SCSI cable can also
be pulled outside of the VT103 to attach additional SCSI
hard drives when a backup is needed - VERY simple!
ENOUGH though. Let us finish by defining whether a
terminal is or is NOT part of a PDP-11. Since I am
voting first, I will start by saying that a basic PDP-11
does NOT include the terminal. However, I can easily
appreciate that many will differ!
Sincerely yours,
Jerome Fine
