Do we have a VAX organization?

All it says is "The city of Umbar was built in the > Second Age by Numenorean voyagers." Absurdly Obtuse! Well, it's accurate even if uninformative :-) It's from Lord of the Rings, as is the name Isildur. Quite what that has to do with anything vaxish, I don't know, though :-) -- Pete Peter Turnbull Network Manager University of York

Do we have a VAX organization?

by Innfogra＠aol.com

One of the big problems that I see is Storage. Paul Pierce had to buy a building to store his collection of big iron, it will become the museum in the future. Big Iron takes space, dry space, with a concrete floor and a loading dock to handle comfortably. Does anyone have extra space. I know of good cheap space in Portland, OR but, as we know rented space is very expensive in the long run. I think it is a good idea to plan ahead for machine deinstalls. They often do come out of service in large batches. Not only are they much less common later but parts and manuals often become very scarce. How about a concrete slab/steel building in the dry part of the South West. Anyone have property or a building for long term storage. I am willing to help with my shipping skills anywhere in the Northwest. Paxton Astoria, OR

Sharp PC-5000 for sale (early 1983 "laptop") update

by mhstein＠usa.net

You know, Sellam, from a marketing perspective that may not be the most effective title for that web page... I didn't know that the printer was an option; thought they all had one; live & learn. IIRC, the bubble memory cartridges alone were abt, $250, at least up here in the rapidly freezing north. -----------------Original message---------------- Date: Sat, 27 Oct 2001 15:58:28 -0700 (PDT) From: Vintage Computer Festival <vcf(a)vintage.org> Subject: Re: Sharp PC-5000 for sale (early 1983 "laptop") update Someone's going to get a hell of a deal. Top offer so far is $77. I'm also throwing in the printer module with this: http://www.siconic.com/crap/sharp_t_printer.jpg

VLB SCSI

by mbbrutman＠magnaspeed.net

I've never had a problem with two Adaptec 2940AU cards, an Adaptec 1542, or 2 Adaptec 1520s. The drivers leave something to be desired once in a while. My 486 VLB system runs a Buslogic BT445S SCSI card (Fast SCSI II) and an ATI Graphics Ultra Pro. The Buslogic has been a wonderful card; it's been in service 7 years now under OS/2, DOS, Winblows, and now Linux. Too bad they were bought out by Mylex, and eventually disappeared into oblivion. Any other Buslogic owners out there? The ATI card was marvellous at the time - 1280x1024 in 256 colors with a 70+ Hz refresh rate. It's a little flakey now - the system requires me to hit the reset switch before it will boot. Replacement ATI VLB cards have been DOA ... apparently they don't age too well.

Big Iron - was Genrad Futuredata info

by mhstein＠usa.net

Having just dropped a rackmount Cromemco System 3 in the process of moving it, I can assure you that it's (relatively) big and there's lots of iron in that PS transformer... and IIRC, it can support around 32 terminals or so running UNIX with the right cards. --------------Original Message-------------- Craig Landrum skrev: >Also, having just joined this list, it would appear to be >dominated by primarily big iron types instead of us IMSAI >and S100 junkies. Assuming there are a few out there and >you wish to correspond, here's what I have: While I agree that there are a lot of rack-mount random TTL junkies here, to some of us, S-100 and things like that are "big iron" as well. =)

first step getting VAX 6000-400 booted ...

The user guide states that the DMB32 supports the LP32 generic printer specification.

first step getting VAX 6000-400 booted ...

So in a MicroVAX 3600 you can go directly from KDA50 controller to RA7x internal drive. Or you can go from KDA50 to bulkhead, bulkhead to bulkhead on next cab (e.g. storage array) and from there a third cable goes internally from bulkhead to final drive. In the case of a 6000 typically you go from KDB50 (or KDM70) to bulkhead on 6000 chassis. Then 6000 chassis to Storage Array chassis. Then internally there is a cable from the Storage Array bulkhead to the drive itself. I don't know how the wiring was done for those later kits that allowed RA9x and/or RA7x drives to live in the bottom of the VAX 6000 chassis. Antonio

Tadpole Sparcbook 2: need bootable software

by bob＠copenhagen.cuug.ab.ca

Greetings all, I wonder if anyone can help me out here. I have a Sparcbook 2 I am trying to resurrect. One of the disks crashed several years ago. I have finally got around to finding a replacement, but now my backup tapes are unreadable, and the CD-ROM I have (NCE 2.0 for Solaris 1.1.1 Version A.2.3) turns out not to be a bootable OS installation CD at all :-( So, I am in search of a CD-ROM of the appropriate kind, or downloadable images of the relevant "stuff" so that I can boot this sucker across a network. I would appreciate a direct reply to my e-mail address so I don't overlook such a reply in the mass of stuff on this mailing list :-) Thanks, Bob. -- Bob Bramwell Snail: 60 Baker Cr.

VLB SCSI?

by ajp166＠bellatlantic.net

-----Original Message----- From: Richard Erlacher <edick(a)idcomm.com> >I still occasionally have contact with one or more of those 5x86/133's, but they >generally had only one VLB slot. I always needed two or more. Whenever I run I have several of them with two VLB slots and video and IDE/floppy combo cards. They are fairly nice with 16mb ram running most anything, they make good linux boxen. Allison
