the best place for memory is in the slot next to the CPU. This is because of the interrupt structure of the PDPs. Actually the memory in a Unibus could go anywhere!

Jerry, I'll take as a spare for the two VT640 terminals that I have. You can send it UPS or US Mail to: Joseph A. Bruno, 612 Main Street, Pittsburgh, PA 15215. I can send you a check to cover shipping if you want. Thanks, Joe.

Thanks, Joe. Since I have no need to further clutter up my office landscape, I will pass on your offer of the manual. Now, if no one wants a VT640 modification for their VT100, I will pitch the add-on board. Any takers?? It's free!! Jerry

According to the manual the VT640 is compatible with the Tektronix Plot 10 software.

Well, Joe, I don't know. Is the VT640 compatible with ANYTHING? Like REGIS, maybe? Sounds like it is an add-on that has had it's day. (As if VT-100 wasn't a clue). Jerry

Jerry, I picked up a couple of those VT640 terminals on the used market several years ago. I have a copy of the manual that goes with them. If you want me to make a copy for you, please let me know. Joe.

Jerry — Uh…I think the RetroGraphics modification to the VT100 gave it some sort of Tektronics (4010?) capability. If Neal Krandall is looking over our shoulder, he will probably know — he used to have a couple at the place where he worked. – Bill

I recently rescued a couple of VT-100's from the salvage yard for parts. One of them had an extra circuit board inside by Digital Engineering, and a logo of `RETRO-GRAPHICS'. When attempting to use this gadget with an RSX-11M TT driver, I would get some interesting and strange results. The…
