VT55 with integrated printer Not thermal or electrostatic >From 1977 until about 1980 we actually used the terminals to print graphics >from bacterial growth curves. The paper exited the side of the terminal. We usually attached a weighted paper clamp to help pull the paper out of the printer. The printer was placed so the paper hung down off the side of the desk or table. The paper was initially wet and came in foil enclosed rolls. The printer generated a spark to discolor the paper at the correct spot, kind of a brownish printing. The paper didn't work if it was dry. Also there was a problem with fungus growth on opened rolls of paper that weren't used for a long time. Maybe caused by the microbiology lab environment. Speed of the paper motion was important, nothing like looking at plots with varied plot speed, scrunched graphs. Picture of the internals of the printer is at http://vt100.net/docs/vt5c-op/ Picture of the printer with the paper hanging out the side is http://vt100.net/docs/vt55e-tm/ Mike McFadden mmcfadden(a)cmh.edu At 02:23 PM 3/5/02 -0800, you wrote: > >--- John Chris Wren <jcwren(a)jcwren.com> wrote: >> This sounds like a machine I used to work on.

I'd suggest trying Mobile One synthetic oil... if it can find leaks that no other oil can find on your engine, it should be alble to flow into all the places oil needs to go... -dq

PDP 7 ?Rescue?

by Innfogra＠aol.com

I have a lead on a PDP 7 coming out of service in the Portland Oregon area. I hope to go look at it on March 19th or 20th. I believe it is still plugged in but out of service. I think it is a late '60s machine. Anyone interested in it please contact me at whoagiii(a)aol.com, not on the list please. I am not interested in getting it. I think that there are very few out there and any left need rescue. I will take pictures when I get a chance to look at it. I would like info on what to look for when I look at the machine.

Loaded uVAX II (Austin, TX)

by mrbill＠mrbill.net

I've got a loaded uVAX II in a BA123, available here in Austin, TX. CPU: KA630-AA two DHV11M multiport serial cards one DHQ11M (8line QBus Async serial card) one DEQNAM QBus etheret adapter one TK50 tape drive has two "H3100" ports for serial breakout boxes on the back; not sure if these are connected to the DHV11Ms or the DHQ11M. Unknown RAM/storage; I havent had time to take the machine out of the back of my truck. The front panel covering the storage control buttons is missing; I have the "back flap" cover, but the plastic "hinge" will need to be replaced. Would like to trade for smaller VAX (VAXstation VLC, etc) or later-model (73,83,93, etc) PDP-11 system. WILL NOT SHIP. You gotta come pick it up at my house. 8-) Also have a BC23K 15-pin-to-1BNC mono monitor cable, free... Bill -- Bill Bradford mrbill(a)mrbill.net Austin, TX

Symbolics rescue (question about picture)

Predecessor to the RK05, and actually re-badged drives from some other manufacturer, the name of which escapes me at the moment. RK05's used a glass reticule for positioning. I think that on-disk format tracks came with the first "Winchester" sealed drives. carl -- carl lowenstein marine physical lab u.c. san diego clowenstein(a)ucsd.edu
