I'm glad for this thread. It kept me from tossing the Commodore 16 box away. Too late though for the beautiful NeXT boxes that went to recycling. I didn't have room. I should have known better. That sound you hear is Larry Walker and Brian Mahoney loading their rifles. colan ____________________________________________________________________ Vintage Computer Collectors List and Info: http://members.xoom.com/T3C Mail us at: T3C(a)xoommail.com -----Original Message----- From: John R.

IBM/XT Y2K Compliancy

by allisonp＠world.std.com

<problems (since I've yet to find an RTC chip that does the Wrong Thing <when the year counter gets to 99). I have five 486 boards that hae older RTC that roll over from 1999 to 1980! they do however set manually to 2000! A board I made using an RTC off a 386 bord has both 1999 to 1980 miss roll (it's stuck. have to fid a different one) and bad leap year. Allison

HP TSB internals

OK, Jay said he thought this was a training manual. That could mean "lab workbook" which didn't get the same amount of polishing as a user manual. Such things tended to get passed around after one guy got sent to the course, too. For example, somewhere around here I have a photocopy of an IMAGE internals lab workbook. The original was obviously produced with the assistance of a typewriter and a flowcharting template, and it looks like someone pencilled some notes on it (maybe while attending the source). Given that I got that copy around 1982 or so, I'd guess that it was originally produced in the late 1970s and before the wide deployment within HP of computerized tools for doing this sort of work (TDP, HPDRAW, graphics terminals, plotters, laser printers, most of which didn't really play together on HP3000s 'til about 1980-1983 or so). 2000E manuals and lab workbooks probably would be from the same or an earlier date. -Frank McConnell

Latest Haul & A DAMNIT (Was: Re: VaxStation 2000 and TK-50Zs)

by Mzthompson＠aol.com

A former co-worker now works for a institution of higher learning. We trade hardware from time to time, and he knows of my affinity for DEC hardware. He told me of two stashes of old DEC stuff at work, and that he had made arrangements for me to haul it off. For various reasons, we had decided to wait until this summer. The DAMNIT ---------- I get a call from him recently. It seems that unbeknownst to him, his boss (another former co-worker), and his boss's boss; some other idiot had decided to clean out the one stash. Since these three are key players in the institution's computer center, it seemed unlikely that this could have happened. But as I said this is an institution of higher learning, and having work for another such institution in this town, I can say with some certainty that it does not indicate 'higher smarts' or one damned bit of common sense. This stash included at least 10 VAXstation 2000's & more than one DECstation 3100. What intrigued me more was the boxes and boxes of unopened DEC spares. We will never know what went into that dumpster. My friend said one dumpster had been hauled off before he knew it. He 'dove' the second dumspter and found that most of the CRT's had been rendered useless, and was unable to recover anything useful. I relate this to you so that all the DEC fans can observe a moment of silence for what has happened with regards to this equipment. PAUSE The Latest Haul --------------- My friend, not wanting this to happen to the second stash, loaded it into the back of his truck at once. He then called me and we made arrangements to meet in a couple of hours. As luck would have it, there came up a storm before we could meet and the VR260 monitors in the back of his truck got a little wet. That does not bother me too much. I had given him an IBM RT with 19" color monitor months ago. It had been in my garage when the tree fell on it during a storm and the monitor got soaked. Six months later, he fired it up and it worked fine. This latest haul is 5 VAXstation 2000's, 5 VR260 monitors and all the cables, mice, etc. Of the 5 VAXstation 2000's, three were apparently running diskless, and the other two have been relieved of their disk drives. Previous Haul ------------- Some time back I hauled home a couple of other VAXstation 2000's & two TK50Z-FA's. One VS2000 is gone and the other has been disassembled to pull the RD54 for a fellow list member. I still have the TK50Z-FA's. To summarize, I have: 3 - VAXstation 2000's - are diskless 2 - VAXstation 2000's - relieved of disks 1 - VAXstation 2000's - basket case, (disassembled and in a basket) 5 - VR260 monochrome monitors 1 - MS400CA (unused) - 2 mb memory option for VS2000 With all the other DEC hardware, I doubt I will ever get to messin' with these. If you have any interest in any of this, let me know. Mike Thompson

DUMB VMS!

by yakowenk＠cs.unc.edu

In reply to some gripe about VMS, Allison replied: ] Dumb huh, it's at least secure! ] Ok go to the netbsd site and nose around, the proceedure for breaking into ] VMS is there... Is it just me, or do those two sentences not belong so close together? :-) Bill.

...and the hits just keep on coming!

by jimw＠agora.rdrop.com

Man, it is turning out to be a real FINE week, if I just don't bankrupt myself in the process! Today I found up an AVA Model 409 Floppy Disk Drive Tester unit (computerized, with auto-test options for 8 inch and 5.25 inch drives, and integral printer). Most cool! These were multi-K$ back when we had one in one of the service centers I worked in. It comes up ok, passes its self-tests and reports its firmware version (2.1) on the printer, but as is common there were no docs with it. I recall using one of these way back when, so I've got most of it down pretty well for now but... (see this coming?) Anyone got a spare (or copyable) manual for this critter? -jim --- jimw(a)computergarage.org The Computer Garage - http://www.computergarage.org Computer Garage Fax - (503) 646-0174

HP TSB internals

by jlwest＠tseinc.com

It is both hand written and printed. A large chunk of it is printed, but obviously not for public publication (ie. internal use only). Many of the printed sections are supplemented with hand written and diagrammed stuff. However, most (but not all) of the hand written stuff is incredibly neat (a ruler was used to draw the figures, etc.). Most of the hand written stuff looked like it was being prepped for overheads. So - than answer is both!

Unibus specs

by danburrows＠mindspring.com

I posted recently copies of the DEC Unibus specs complete with timing and other goodies on Zane's site. Thanks Zane for the space.:) They are mostly GIF images and the ones that had fine printing on the charts there are 2 copies. Same file # just a suffix letter difference. The url is ftp://zane.brouhaha.com/pub/dan/DEC/Unibus_spec Dan
