Hi All, I'm going to be attempting to repair, both cosmetically and operationally, a circuit board that had a strip of 12 volt trace "blown off" of it by a short. The fiberglass is clean and there was no solder resist in the affected area. I'm considering using 3M 1183 adhesive tinned foil

I use `groff` for some tasks like that. If it's a simple document I'll only ever do once, I often just open it with a text editor and set the editor to display a bar on the 76th column, and manually hit return :) There are probably Markdown preprocessors that either produce fixed width text or

Depends on the OS, and the model of the printer, and what its interface is. If it's a printer that DEC software understands, the WPS family of word processing software would be a nice option. There's WPS-8, WPS-PLUS for RSTS, various others probably as well. paul > On Aug 10, 2020,

Hi, I want to use my daisy wheel printer to create letters and memos and similar (rather simple) texts. What can I use to write the text? I think "special effects" with daisy wheel printers are "bold" and "underline" parts. And "double stroke" (if that's the correct word, I mean a space

That's a very interesting comment, got me to thinking.  The VR150 was connected to a working Vax Station 3100 with the proper DEC cable and I observed the non-working behavior.  However, the color RGB output from the VS3100 works just fine, I boot the machine into VMS and runs just OK (but

One comment...if you don't have the correct cable and a system that is set for the correct refresh rate, it may appear that the monitor does not work. Be sure you have compatible equipment. This was a specialized display. Bill On Mon, Aug 10, 2020 at 1:19 PM Douglas Taylor via cctalk <

Josh; I have a DEC VR150 that is nearly functional; shows full screen but the H/V are not in any sync at all.  Would love to use it with a VaxStation 3100. Opened it up and found it quite a complicated monitor, not like a simple PC monochrome monitor. Purchased a microfiche manual off
