  This was much bigger than a mulltiprogrammer. I've seen a bunch of those
and they're only about 6 or 8" tall. This appeared to be much taller. The
multiprommers are operated by an exteranl computer. Apparently these
contain a computer similar to a HP 1000.

   I couldn't see the front or back so I don't know if it's rack mounted or
not, it appears to be able the same width as a rack.

   There was a bunch of interfaces and disk drives around for the 98xx
machines so that may be what this is. It looke like it may have a keyboard
sticking out and a CRT mounted above so it may have a 9845 installed. I'm
going to have to go back there when I'm not rushed and take a better look.

    A 9845 or 9835B with a CRT is pretty good size just by itself.
