Jerome Fine replies:
While the RX50 is still a very standard drive for real DEC PDP-11 hardware,
the RX23 (3 1/2" 1.44 MByte floppy drive equivalent to and probably identical
to the same drive on a PeeCee) is very rare on a PDP-11. The uVAX 3100
did have a special SCSI adapter to use the RX23, so I presume that the RX23
was more widely used with that system.
However, if Ersatz-11 is being used, then PDP-11 software is being run -
obviously.
So an RX50 would be widely in use. The first time I ever wanted accept some
work for a PDP-11 that was to be delivered out of town via the internet was
on a system that used an RX50 at both ends. PUTR was the perfect solution
for small files of less than 800 blocks. Just copy them to an RX50 on the PDP-11
at my end, use PUTR to copy the file to the Windows 95 (it was 3 years ago)
directory (and don't forget SET COPY BINARY), attach the file to an e-mail.
At the other end, the reverse was done. PERFECT and fast - about 10 minutes
from the time I copied the file to the RX50 at my end until the copy was made
from the RX50 at the other end to the target PDP-11 to run the program. It did
not hurt that TSX-PLUS was the operating system being used which is compatible
with RT-11.
