- I have a pile of these too -- but note, the 8650 can do RS232
- as well as current loop! You can hook modern terminals to
- them at up to 2400 baud, and even faster if you use jumpers
- to points not advertised in the manual. Read the extended
- comments in the board schematics for the M8650 to find out
- how to make the RS232 cable and how to jumper for higher
- speeds.
- > Supplies? I've got a _lot_ of blank 1" paper tape.
- I got cases and cased of oiled fanfold and roll tape, mostly
- black, but also a case of dark grey. No DEC original tape,
- though.

- I have the EDUSYSTEM-30 user's guide (mark-sense batch BASIC),
- The EDUSYSTEM-10 user's guide (basic, but minimal), the
- EDUSYSTEM Produce Catalog, including an undated letter
- offering price quotes, circa 1971, and a copy of the
- Educational Program Index from the same era. All are DEC
- originals. Sorry I don't have the software itself.

- I don't know about everybody, but one "goldenrod" handle
- would do me a world of good. (Goldenrod is the official
- DEC name for the yellow color that goes opposite terra
- cotta on the PDP-8/E front panel).

- I think it's a standard kind of cloth ribbon. If worse comes
- to worse, the width of the ribbon is exactly standard, so al
- you have to do is wind a ribbon from whatever kind of spool
- you get onto the ASR33 spool.

- Strip out the bad filters. If your air is dirty enough to
- need filtering, go to a furnace store and look at the filter
- media they have to offer. I've seen some "plastic" furnace
- filter material that's not too different from the DEC stuff,
- but thicker. I assume it'd work well enough if you can get
- it to fit in the path of the airflow. I've got a rack-mount
- system with no air filters (at least, none remaning) inside
- the rack. The top-of-rack fan still has a filter, though,
- but just about anything can be stuffed there.
