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

Where can I find 5.25 DS/DD disks?

by retro＠retrobits.com

Hello all, I have a couple of questions regarding 5.25 inch, DS/DD disks... First, where is the best place to buy some new ones? Second, does any manufacturer still produce this media, and what is the shelf life? Basically, what I'm asking here is, will our 5.25 drives become useless before too much longer? I remember a discussion on the group a while back regarding the use of HD media in DD drives. After reading about two thousand messages more complicated than quantum mechanics, I gave up trying to figure it out :-) So now I've resigned myself to seek the newest 5.25 DS/DD disks that I can find. Any help appreciated! Long live my Commodore 128! Thanks in advance, Earl Evans retro(a)retrobits.com Enjoy Retrocomputing! Join us at http://www.retrobits.com

The Original MS-DOS 4.0

by dhquebbeman＠theestopinalgroup.com

This might be a topic better posted in the alt.folklore.computers USENET group, but let me try here first. This is from memory, and it's not as reliable as I'd like it to be. IIRC, OS/2 was not Microsoft's first attempt to create a multitasking operating system. They were working on, and I believe mostly finished, a DOS 4.0 that was multitasking. This was not the PC-DOS 4.0 for IBM, nor was it the MS-DOS 4.0 that we finally saw here in the states. This multitasking DOS 4.0 (from Microsoft, not a third party) was supplied with a computer that was old only in either the UK or more widely in Europe. It seems that the first letter of the computer manufacturer was an 'A', so the machine could have been an Apricot, an Amstrad, an Acorn, or lord knows. I read about this machine either in Byte during the late 80s or in a BIX conference (I MISS BIX!). I've searched the web for references to this multitasking MS-DOS 4, and have found nothing. Does anyone else remember this? Was the Byte article reviewing a sample of a product that never shipped? Did anyone get their hands on one? Does anyone have it? -doug q
