DIY Paper Tape Punch - Mechanism diagram?

If you were to build a custom >linear drive it might work. But also very slow. Hmm. You could have N fixed lasers at the spots of potential holes, and then a mechanism to move the whole assembly of them in the shape of a single hole, drawing them all at once. You could have one laser on that moved precisely along the hole row, and use the same sort of mechanical motion to draw a hole. How much laser do you need to cut paper, how much to cut mylar? Were there any paper tape devices that did not use the sprocket holes to move the tape? - John

Lear Sieglar Terminal

by sales＠elecplus.com

I have in my shop a small blue old Lear Sieglar terminal. I does power on, but it gets a screen full of garbage. It is missing numerous keycaps. There are several cracks in the case around the keyboard. Asking $200; local pickup only. Pictures on request.

In search of Three Rivers PERQ 1 Keyboard

by ian.finder＠gmail.com

Title says it. It saddens me that in this day and age I have to call this out but: ? This is for use with an actual real PERQ 1, not a Raspberry Pi running an emulator, nor something I?m looking for because I like to collect only the steering wheels off vintage Porsches because they ?feel nice? or ?look cool? or will ?make me a better programmer.? Actually perhaps a better analogy involves elephants and ivory... but I?m now off topic. Anyway- cruelty free, no-poach, free-range use intended. Thanks in advance for any leads or on-topic discussion of the keyboard protocol to tide me over in the meantime... With all the time on my hands from the shutdown it?d be great to make this system whole and start down the long path toward restoration.

Imlac/Hazeltine Dynagraphic terminals?

by derschjo＠gmail.com

Anyone have any idea if any Imlac/Hazeltine Dynagraphic terminals are still around? I've never heard tell of one beyond marketing information. These were late vector-graphics terminals made by Imlac Corporation after they got bought out by Hazeltine in the late 1970s. Any technical docs (programming, architecture) would be interesting to look at. And if anyone knows of one hiding in a basement somewhere... - Josh

Did anybody ever came across the DEC CI750 User Guide?

by p.gebhardt＠ymail.com

Hello all, the headline says it all. DEC document number is EK-CI750-UG I've been looking for that one for years but never came across a paper copy or scanned document. Does anybody know where to get one? The technical description and the schematics are available, though. Thanks for any feedback on this.
