Hello - I pulled 2 IBM 6091 19" monitors out of the trash. I think they were used on their power pc computers. I need info on this monitor, such as resolution, refresh rate and what are the white and black bnc connectors for. Any help is appreciated. john -- ************************************************************************ * * * * John Ott * Email: jott(a)saturn.ee.nd.edu * * Dept.

Fw: X-32 boards

by dburrows＠netpath.net

The following is from a PDP11/Mass Spec customer of mine. If anyone has any ideas for him feel free to contact either of us. I will just forward anything to him if it gets posted to me or the list. With a little direction he can run diagnostics and has available an electronics shop and decent test equipment like scopes. I don't know if they have things like logic analyzers however. ( I did not need one the one time I was on site) It even meets the 10 year rule.:) Dan ---------------- We have an X-32 computer (CPU/3), a German unix machine from 1989. This computer operates a Bruker AMX-500 NMR spectrometer. The computer is functional except that Fourier transform calculations frequently give a massive "transmitter" spike that is NOT hardware related. Although we normally do all repairs through Bruker, the director of our facility does not want to repair this problem because the computer will be replaced within a year and the instrument is functional. However, for a frequent user (me), this problem is extremely frustrating and time-consuming. The problem is almost certainly one of the three following X-32 boards: CPU board H2297 ECL 12 Memory 16MB H2271 ECL 02 Array Processor H2231 ECL 06 If anyone can help with this problem, please contact me by email. Thank you.

Minivac 601 documentation?

Sellam - I'm going to be out of town on a family vacation for the next 10 days or so. I'll drop you a note when I return to see if we can hook up on the Minivac doc.

DEC CPU bulkhead issues

by Wm.King＠eng.sun.com

Chuck, Does this have a switch to select between AUI and 10-Base-2? I've recently repaired two systems where the switch was dirty and didn't make a good electrical connection. The symptoms were that the AUI port received, but wouldn't transmit. Maybe that's the problem. Bill

My first embedded systems project (the Olicon MVP-035 Radiographic Viewer) had a PhD in C.S. working for six months on the project- all he had to show at the end of it was flowcharts. In six weeks the engineer and I had an operational prototype (needless to say we ditched his flowcharts). -dq

Paint JObs (was Re: Restoration of Discolored Plastic)

by xds_sigma7＠hotmail.com

In my IBM experience, I can personally confirm the existence of the following colors: Black (The modern standard) Blue (I have a 3262 line printer this color) Gray/grey <- this is what I think is the standard color, though the standard color depends on what line of machines we're talking about.. (My S/36 (5360), both 8100's (8140 and 8150), both 8809 MTD's, and all of my 8101 and 8102 disk drives are this color. Red (I've seen a 3380 this color) Yellow (I have a 3262 line printer in this color, yuck-o) I'm not saying that there might not be other colors, I'm just confirming that these colors do exist.

Restoration of Discolored Plastic

by dhquebbeman＠theestopinalgroup.com

Without getting the entire "Preserve vs. Restore" argument started again, has anyone ever found a way to restore the original beige color to plastic skins that have discolored due to long exposure to UV? I'm assuming what's happening is more than just the lighter elements of the plastic evaporating, but rather that some kind of chemical change is taking place that likely can't be reversed. I would think paint to not be a solution; at least not for me, as it always takes better hand/eye coordination than I can manage. How about dyes? Has anyone tried some kind of analine dye to restore beige plastic? Dyes spread more evenly and I think can even penetrate perhaps a few microns. thanks, -doug quebbeman

> Gray/grey <- this is what I think is the standard color, My Model 711 Card Reader and Model 716 Line Printer (my first foolish acquisitions, gotten in the 70's and mostly disposed of in the 80's) were gray as you say. -dq
