I must have at least 6 in use plus another here at home. Two of those were installed to support Plextor CDwriters exclusively on systems with IDE disks. Mixing drive interface types on SCSI busses is somthing I DO NOT do, two many performance impacts. Allison

Ack! Where did all the VCF4 go??

by spectre＠stockholm.ptloma.edu

Did someone preserve the pictures from VCF4? Curt's excellent retrospective on AtariHistory.com doesn't work anymore :-/ http://www.atari-history.com/vcf4/vcf4.html Clicking on the pictures (except vendor2.html) just gives 404s. -- ----------------------------- personal page: http://www.armory.com/~spectre/ -- Cameron Kaiser, Point Loma Nazarene University * ckaiser(a)stockholm.ptloma.edu -- It is not enough to succeed.

2 more Finds for the musuem

by jrkeys＠concentric.net

Well today I hit a small jackpot in that I got a almost complete HP 200LX palmtop PC with 1MB ram, leather carrying case, 3 manuals and other papers, a set of four connectors all new and still wrapped in plastic unopened. It's missing the cable for connecting it to a desktop unit. My other find is a complete Brainiac toy computer from the 1950's. This unit is in it original box with all the parts for building your own wooden computer that really works for doing math and other small task. One of the light bulbs is broken and will need a replacement. The manual is there and seems to be complete also but is showing it's age. Now if I can just find a Geniac toy computer also ???

SCSI connectivity

I use Snooper, but I never Norton, Snooper, DRivX and a few others. Generally if I needs speed IDE does it well enough.

ISA poops out at 8-10mhz. >I am not trying to be rude, or make enemies, but why are you on a >classic computer list? Your rude. ;) I am an original Altair owner and have a list of classics including things like PDP-8F, PDP-11, Northstar, KIM-1, ELF, TI99/4 and a raft of CP/M systems based on S100. I can even say that most systems are operational with a bunch of the oldies still cranking real work. I've always pushed the hardware for just a bit more. PCs however tend to raise my contempt as not all are quality hardware. I have PCs too but few are "classic" to me despite their age. I consider the PS/2 50Z and my Leading Edge model D to be good examples of PC hardware. This is not to say I'm not skilled at getting all of the performance a PC can deliver. >Sure I want my old computers to run, but I want it to be a fast as I can get >it, while maintaining reliably. ;) and thats something new?

From: Chad Fernandez <fernande(a)internet1.net> >What I want it one of the later 1542 cards that isn't plug an play, but >will handle drives over 1 gig. Both my 1542s have the earlier bios and >won't go over 1 gig :-( > ???? The 1542 in the domain server (an old P100) has a 2.7 gb drive in a single partition. You have a bios problem not an interface problem. Allison

Keeper needed for RSTS and other stuff

by kyrrin＠bluefeathertech.com

Fellow CLASSICCMP'ers, As you may remember, my interests are shifting away from computing and back to ham radio. As a result, I'm in the process of going through my stuff and clearing out what I don't want to keep. Part of my accumulation is a library of RSTS/E releases on 9-track tape. The library covers a range of 7.2 to 9.0, and there are also numerous other reels of miscellany, all on their own floorstand rack about four feet high. I need to find a keeper, or librarian for this. It would be difficult to ship, so I would like to find someone local (WA State, near Seattle) to pick them up and give them a good home, and be ready to, say, copy a distro if someone needed it. Please contact me off-list if you're willing to be the "RSTS/E Archivist." More posts coming up for more goodies. Thanks. -=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=- Bruce Lane, Owner and head honcho, Blue Feather Technologies http://www.bluefeathertech.com // E-mail: kyrrin(a)bluefeathertech.com Amateur Radio: WD6EOS since Dec.

I've had the commercial ticket for 31 years but it's time for the HAM. Radio is my second love. Allison

Stuff Available (WA state)

by kyrrin＠bluefeathertech.com

(CC to classiccmp and port-vax) I have a MicroVAX II, complete, in a four-foot mini-rack with a Fujitsu 'Super Eagle' disk drive and Cipher 880 tape drive. Everything worked the last time I had it powered (about a year ago). I want it to have a good home, but I also have some time and cleanup effort invested in it, so I'd like to ask for $50.00 or best offer. LOCAL PICKUP ONLY. It's too bulky for me to ship. (Kent, WA, southeast of Seattle). Also available: -- Two complete VCB02 video subsystems for the MicroVAX II/III. We're talking boards, cables, cab kit, mice, KB's and monitors. MAKE ME AN OFFER. -- At least one, possibly two, BA23 enclosures with hardware and panels (hardware may require some digging to find). -- Spare boards! MV-II CPU's, memory, etc. I know I have some Dilog ESDI/Q-bus controllers, and there's probably some SMD boards in there as well. Prices to be determined, probably best to make me an offer depending on what you need and what I have. -- Seagate 'Saber' SMD drives, 850MB. These are nice units in their own trays, with power supply and LCD display diagnostics front panel. I have at least two left, possibly three. $25.00 each. -- PDP-11/73: I know I have at least one. Help me dig it out and we'll see! ;-) Lord only knows what else I've got in there... I have yet to go through numerous crates of stuff, but my plan is to clear out pretty much anything that I won't need to keep our server farm/Internet presence intact and healthy. This means most of my DEC stuff. Thanks in advance. -=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=- Bruce Lane, Owner and head honcho, Blue Feather Technologies http://www.bluefeathertech.com // E-mail: kyrrin(a)bluefeathertech.com Amateur Radio: WD6EOS since Dec.

Identifying parts on a VT100 logic board
