Was reading the Wikipedia article on Drum memories:
https://en.wikipedia.org/wiki/Drum_memory#External_links
And came across this tidbit.
As late as 1980, PDP-11/45 machines using magnetic core main memory
and drums for swapping were still in use at many of the original UNIX
sites.
Any
Thanks everyone!

Great! thank you Glen and also Michael T. for the identifications.
So this appears to be a PDP-11/23 with this FC-202 floppy controller.
1. I have read that the card and the drives were compatible with the dec rx02
drives.
The US Letter size of folded Versatec paper came in a cardboard box that
was really good for compartmentalizing small stuff and stacking for
storage! I used to scrounge around the waste containers for empty, used
boxes. Still have many in use.

It wasn't just Versatec plotters that used this mixture - standard office
photocopiers also had clay-coated paper and liquid toner. I don't know what
allowed the change to plain-paper copiers (which use an intermediate
photosensitive drum, like a laser printer) but it was probably the expiry

I scrapped a similar Redactron mag card Selectric unit 30-odd years ago;
still have the card drives, shoulda kept the Selectric.

My wife did, sort of: for a while she worked with IBM MT/ST word processors.
Those were very early word processing systems
I have a Versatec interface here somewhere, but I don't remember if it is
for an 8 or 11.

Does anyone else have one in their collection?
I have an ICL-badged V80 which has a GPIB interface to link it to a
PERQ. I also have the
