Greetings I'm looking for any and all information I can find on the DEC Rainbow ethernet cards. I know for sure that two exist, both plugged into the communications slot that most rainbows have filled with a hard disk controller. DEC made one, and Univation made the other. Univation also advertised a ARCnet card, but I found that only in one issue of Digital Review and the next issue moved up to Ethernet. So far all I've been able to find is DECnet DOS/Rainbow 1.0 which might have drivers for the former on it. I've seen no trace of the latter. Also, is there a convenient way to extract teledisk disks these days to something like an image file on Linux/FreeBSD? MAME almost can do this (I can read it in with the Rainbow emulator and diskcopy to a flat file that I can then examine), but I was hoping there was a tar-like tool to do the deed. Warner

IBM PC diagnostics disks

by rsmilward＠frontier.com

I have these 5-1/4" diagnostics disks but no need for them. If you're interested, I'll send them to you for the cost of the postage from Durham, NC. * Diagnostics for IBM Personal Computer AT, ver. 2.03 copyright 1981, 1986 maroon disk label, p/n 6183111 * Advanced Diagnostics, ver. 2.20, copyright 1981, 1986 dark blue label, p/n 6139804 They are in excellent physical condition. Sorry, I don't have the manuals. (I used to work for a ComputerLand store in '81-'82 and probably acquired them there.) They might be available for download somewhere, but these are the physical, displayable versions. **Richard

30 yrs. ago

by c.murray.mccullough＠gmail.com

30 years ago this month the IBM PC debuted at $1565. Some say this began the era of mass-computing and it is now what classiccmp.org <cctalk at classiccmp.org> is all about! For those interested in the OS world LINUX is 30 years old. Time has passed but this is what classic computing is all about. Happy computing. Murray ?

VT101 free to good home, pick up in w. Oregon

by invi＠vivaldi.net

It was sitting in the trash. No keyboard, no power cord. Case was open and some of the bundles of wires inside are disconnected, so I doubt it's in working condition. I'm not much of a hardware collector, so I was hoping to put it in the hands of someone who would like it.

My apologies. ? It was 40 years ago that the IBM PC became a retail computer this month. Murray ?

How do CRT's age?

by healyzh＠avanthar.com

Odd question, how well do CRT?s age? Just the CRT, if what I think exists, is actually there, they?ve never been in Oscilloscopes. Zane

I have repaired it several times (most recently, visibly bad electrolytics in the switching PS startup circuit). In fact that's the second time the power supply has failed - the first time was years ago and I just replaced the board. Now it's crinkling the bottom of pages... there used to be a kit to fix that. I love those old "bricks". Although mine is like my grandfather's axe (new head and new handle but it's still my grandpa's axe) :) The trick nowadays is finding toner cartridges that weren't just refilled, but actually rebuilt (with a new wiper blade). -Charles

Early '80s Motorola Semiconductor Reference - anyone?

by bear＠typewritten.org

Anyone have an early ?80s Motorola semiconductor reference manual? I am attempting to repair a Boschert power supply from ~1983 that is full of Motorola parts marked as 1027 (DO-42ish), 1077 (TO-3ish), 1078 (DO-5ish), etc. It would be extremely helpful to know their specifications, or ideally how to cross-ref them to ?standard? parts. ok bear.
