Jerome Fine replies:
OK, but do you OR do you not COUNT the terminal
as part of the total size when using a DECmate III system?
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
