Subject: Need help with VTserver
Thanks to a creative suggestion from Ethan, I want to use VTserver
to transfer a bootable OS/8 RL02 image from my laptop (which works
fine under SIMH PDP-8) to an RL02 pack on my 11/23+. Then I will
remove that disk from the drive on the -11, place it in the 8/A's
RL02 drive, and voila - it should boot OS/8! (The disks are
identical format regardless of system, only the programs
themselves differ).
I never used VTserver ... and I would never have tought of using
VTserver with a *PDP-11* to load *PDP-8* software!
Very interesting twist :-)
I am not sure if it will work. Let me explain why.
Using VTserver to load OS/8 (pdp8 software) into the memory of
the PDP-11 will work, I guess. So far, it is just data words
that you are transfering. However, when you write the data to
disk you use the RT11 file structure. If the RT11 structure
is identical to the file structure used by OS/8, I guess it
will work, else ...
Using VTserver to transfer any "smallish" pdp8 software to
a PDP-11 and then *punch* on papertape would work, I guess.
