  Nice! It's a 9836 with a color monitor. The color versions are sort of
scarce.

    Yeap.

    I have all kinds of stuff for them. I also know that Gail Roth as
manuals for it that she's been trying to sale on E-bay. I think she only
got one bid and only for one manual.

  Info: These are similar to the 9816 (9000 series 216) and 9826 (9000
series 226) and the 9837. The 9836 is also called a 9000 series 236. They
all use 8 MHz 68000 CPUs except the U versions, they have a 12.5 MHz 68010.
 They'll all run HPL, Pascal and BASIC. The languages are available on ROM
cards or disk based. I have all of them on disk but the ROM cards are rare.
I have a couple of them with BASIC but I've never found the HPL or Pascal
versions.

       Hmm. that looks like the part number for an individual part. Look
and she if you can find a model number for the whole thing. It should be
simply a four or five digit number with no dash number.

     Oh, Ok then I know what it is. Does it plug into a interface slot on
the back of a 9825, 9835 or 9845 and have right angle bend in it? If so
it's an entender for working on interfaces.

    They're ROM drawers for a 9835.

  PS you can't replace the surface of the 9872 plotter. It has wires
embedded in it that carry the high voltage that's used to create the static
charge that is used to hold the paper to the surface.
