OpenVMS Hobbyist CD, Reading under Linux/BSD ?

by jwb＠paravolve.net

I want to attempt to install OpenVMS 7.2 via MOP over the network, to do this I need to get the files off the CD since I don't actually have another VAX to read the CD on. (I'm using a Linux host running mopd... I was able to install NetBSD that way) Anyone know how I could read the data off the CD under Linux or *BSD ? -jwb

Vaxen vultures on ebay ... and is "rtlacy" here?

by gunther＠aurora.regenstrief.org

Hi, Joe Moir from Boston just did the ultimate sell off of his VAX11 gear. Boy the stuff went for $50 per box. An 11/780, 11/785, and an 11/795, ahem, 8650. The were all in ugly parted out shape, but significant sources for spares. I now have an 11/785 backplane, and since my 11/780 doesn't work properly anyway, I can just as well start converting it. I almost had all three of those, but a fellow with ebay name "rtlacy" had made a little more decisive bids on them. Now I wonder, just in case, is anyone of you out in the Boston area, just in case? regards, -Gunther

ebay bid on dec rack

by jwest＠kwcorp.com

FYI - I'm likely going to be bidding on the DEC "3 high" rack on Ebay that includes an RA81. The RA81 is missing the HDA, and I have no need for it, I just want the rack as it's the right height to mate to my 11/44X. If anyone wants the RA81-HDA, let me know before it gets skipped. Jay West

PDP 8/L repair log - hopefully the LAST installment!

by charlesmorris＠direcway.com

The 8/L is finally fixed! The final interesting failures were: The Group 2 microinstructions (CLA, IAC, etc) would not work. Changed the relevant 7400 - still only weak wiggles. Tracked it down to a dead short on the AC CLEAR line. Turns out that one of the ground bus strips that run the length of the backplane had buckled just enough to touch the exposed wire at the bottom of the pin it was supposed to make a circle around! That was really fun to locate. Lastly, the TTY receiver card M706 would only work when on an extender card. When in the backplane it would receive only one character and "hang" until power cycled. I spent a lot of time in a fruitless search for a bad backplane contact. Finally I found on the stop bit flipflops that their PRESET pins were floating (a frequent bad habit of DEC in their early design was to leave uncommitted TTL inputs to float, which works fine as long as it's an electrically "quiet" environment. Which a card handling 20mA TTY signals is NOT). A quick 1K pullup to +5 and it hasn't dropped a bit since. I've just finished constructing my "DF32x4" disk simulator (PC boards in a 1U [1.75" high] rack chassis). I'm starting to debug now - so far I had a bad IDC connector and (of course) no spare. I will make Eagle .SCH and .BRD files available to anyone who wants them IF it ever works ;) -Charles [demime 1.01a removed an attachment of type image/jpeg which had a name of mvc-457e.jpg]

What is this? eBay #3409766995

by melamy＠earthlink.net

considering that the processor and eproms are missing. It looks to me to be a 8080 based board. The 28 pin chip close to the forty pin missing chip could be the 8228. The metal area to the left was probably where a breadbaord strip used to be. There are LEDs and a connector strip close to the breadboard area. It looks like a electronics experimenter system actually. His reference to the first laptop is pretty silly. best regards, Steve Thatcher >--- Original Message --- >From: acme(a)ao.net >To: cctalk(a)classiccmp.org >Date: 3/28/03 9:32:48 AM > Described as "One of the first portable computers ever made," hex keypad, >the word "Eclipse" on side of unit, fits in a briefcase, seller claims it >was made for Lawrence Livermore Labs. > >Any ideas? > >Glen >0/0

Fw: AdamComputer.com domains

by jwest＠classiccmp.org

Question.... Was there a vintage computer called an "Adam"? I *THINK* I recall hearing something about that name. If so, then the below email MAY be of interest to someone. If there wasn't such a computer, then this email is SPAM and I apologize for posting it here.

Maybe this?: http://home.pacbell.net/mmetzler/discuss.txt <quote> Subject: Lawrence Livermore Computer Date: Mon, 23 Nov 1998 09:57:32 -0800 From: "Mike Mori" To: I was refered to your web page by Doug Yowza. I was hoping that you would have some information on a LLL MST-80 microprocessor trainer I found a few years back. The unit is a Intel 8080 based single board system with a keypad and 3 digit display. It is mounted in a briefcase with a proto board and power supply. Any info you might have would be greatly appreciated. Thanks. </quote> -----Original Message----- From: acme(a)ao.net [mailto:acme@ao.net] Sent: Friday, March 28, 2003 11:33 AM To: cctalk(a)classiccmp.org Subject: What is this? eBay #3409766995 Described as "One of the first portable computers ever made," hex keypad, the word "Eclipse" on side of unit, fits in a briefcase, seller claims it was made for Lawrence Livermore Labs.
