And, if I did have one, has anyone written an

would it be hard?
From what I can tell it was driven by a serial
port and in looking
around I thought I saw docs describing the protocol, so if you
something that generates the chatter you could stick something on the
other end of that serial line and emulate the output.
Most stuff from that era also talks Tektronix 4010 and everything
emulates that, whether its physical terminals or terminal emulators.
As described in another thread by Al, the VS60 was a VT48 display subsystem
using a local 11/34 processor. The VT48 display was BIG (20" or so diameter)
and was a vector/stroke display processor with a light pen interface and
button box. Too many lines on your schematic and it would start to flicker.
As I used it for SUDS at DEC, we ran the VS60 back to a TOPS-10 system via
dedicated high speed serial lines (KMC11 IIRC). The VS60 (11/34 + VT48) ran
a custom program that implemented the SUDS display subsystem. SUDS actually
ran on the PDP-10 (a KL10 running TOPS-10 v7.xx); the VS60 was just a big
I don't know that I ever heard what the 'S' in 'S.Foonly' was supposed
stand for ... maybe SUDS or Stanford, I guess.
