Two Hewlett-Packard Integrity rx2620 systems, with dual 9015 "Montecito" (IA-64 with hyperthreading, VT-x, etc.) dual-core processors, 24 Gbytes RAM, iLO/MP board and plenty of options (Ultra320 SCSI RAID, 10GbE, GbE-and-FC combo cards and much more). I should note, the processors have been installed last year, brand-new out of the box! (In fact, I can even deliver the original CPU boxes, with processor tools, included documents and so forth.) This type of CPU supports HPVM (also known as Integrity VM), which is a fairly recent feature. In any event, please contact me for more information, offers or potential trades (I'm in particular looking for SGI parts). I can also show pictures and arrange a 'test drive' or 'tour' via SSH or Telnet. The systems are located in the Netherlands and I'm willing to ship (internationally). - MG

FS: 2× DEC PWS 500au

by marcogb＠xs4all.nl

Two Digital (Equipment Corp.) Personal WorkStation 500au systems, each with a stock 500 MHz EV56 CPU (socketed), 1? Gbytes memory, on-board DE500 Fast Ethernet NIC, on-board SCSI, on-board (MMOV- compatible) Ensoniq ES1888 audio, additional DE450 NIC, PowerStorm 3D30, an additional QLogic SCSI controller (same type as on-board). One of the two may have a weak battery, but it's fortunately a regular button cell type battery. I have various options to offer. In any event, please contact me for more information, offers or potential trades (I'm in particular looking for SGI parts). I can also show pictures and arrange a 'test drive' or 'tour' via SSH or Telnet. The systems are located in the Netherlands and I'm willing to ship (internationally). - MG

It's funny how for many, the "IBM PC 5150" is not an "IBM PC kind of computer". I'm sure somebody here did it. 5150 with a CM153 card for Philips CM100 player? Tim.

Motorola 6800 evaluation kit

by stacymcarr＠gmail.com

I am looking for a Motorola 6800 evaluation kit with books. I sold one that I built in 1976 which I sold in 1992. I would like to find one that is for sale, hopefully the same one, if not one in good shape.

RIP Mark Crispin

by tshoppa＠wmata.com

I traded E-mails with Mark for three different decades and got to visit him several times in the 90's whenever I was passing through Seattle. Hop on the ferry, have deep political discussions with him (although I never exactly agreed with him he was always willing to discuss!) at the diner, and play with KS-10's, TU-77's, and Massbus disks. Rest in peace, Mark. Tim.

Ohio Scientific floppy disk images

by bear＠typewritten.org

Howdy folks. I have a handful of 5.25" floppy disks for an Ohio Scientific C1, which I would like to image. Anyone have any info on this disk format, or know of a tool that can read them? They don't appear to be in a WD177x-style format... at least not one intelligible to ImageDisk or Tim Mann's catweasel tools. There is at least one C1 emulator out there with support for disk image files, so I have some hope somebody's already done the dirty work for me. If nothing already exists, low-level info on the format would be awesome as then I'd have something to work with, trying to extend Karsten Scheibler's catweasel tools. A few cursory trudges through t3h Googles have borne little fruit so far. ok bear. -- until further notice

Looking for info on Apple II card- Labnet 488

by dfnr2＠yahoo.com

Hi all, I recently acquired Labnet 488 card by Innovations in Computing, circa 1978.? This appears to be an IEEE-488 interface based on the Motorola 68488 chip.? Does anybody have any info on this card, or even better, has anybody seen one of these in use?? It would be cool to locate manuals and/or software, and actually put this sucker to use. Dave

Thanks for the replies - yes its a BA123 - just like the picture :) The system is in the UK. It is a nice machine as it usefully sits next to (or under a large) desk so doesnt take too much space. I'll get some pictures and specs online shortly.

World's largest Mindset Computer Corp Collection available

by curt＠atarimuseum.com

Hi all, Been having some health issues as of late and bills are pouring in faster than money is coming in so I have to make a tough decision and sell my Mindset Computer Corporation Collection. I am only selling as a whole as I don't want this collection broken up. I'm gauging interest, please email at: curt(at)atarimuseum(dot)com Many have seen quite a lot of my collection as it was on display at a recent VCF East show and one an award. I have over a 1/2 dozen CPU units, expansion modules, plug in peripheral modules, keyboards, joysticks, mice, tons of software, applications, and games, many are in original boxes and are original disks, I have a huge developers manual, marketing materials, units in boxes, a keyboard in a box, peripheral accessories in boxes (many in never opened/sealed boxes), I have one of the only Mindset software carrying case bags, and much more. Need to put together a more detailed inventory, but it is extensive. Here are some photo's of a good bit of the collection (monitors are not included): http://vintagecomputer.net/vcf7/Exhibits/Mindset_exhib_Vendel2.jpg http://vintagecomputer.net/vcf7/Exhibits/Mindset_exhib_Vendel1.jpg http://vintagecomputer.net/vcf7/Exhibits/Mindset_exhib_Vendel4.jpg http://vintagecomputer.net/vcf7/Exhibits/Mindset_exhib_Vendel3.jpg Will also included domain: www.mindsetcomputer.com with sale...

CFFA3000 and Apple III?

by wheagy＠gmail.com

Great, thanks. I'll give the cleaning process a try before a speed adjustment. Thanks...Win ---- Almost all the A3 drives that have come my way were malfunctioning. Best bet is to disassemble them and carefully clean and lube. First, use some canned air to blow out all the dust bunnies. The original grease used on the head assembly rails and the spiral-cut plastic stepper wheel solidifies over the years. I usually use a tiny bit of WD-40 on a swab to remove the old lubricant, then a bit of Tri-Flow to replace it. A speed adjustment may very well be needed, but another problem area is the two trimpots on the top of the drive circuit board. They tend to grow oxide and become intermittant. Mark the position of the pots with a felt-tipped pen, then wiggle them with a screwdriver until the little gob of locking compound breaks. Squirt a small amount of non-residue control cleaner in the side and work them through their rotation a few times. Reset to the marked position. You can lock them in place again with a dab of nail polish, but don't do this until you know that things are working again! Reseat all the chips on the board and check closely for "black pin" syndrome. For some reason, the chips in the disk drives seem more prone to this (more exposure to humidity?) If you see this, pull all of them and take a contact cleaning tool to the legs. Finally, take a swab and carefully clean the head with isopropyl alcohol. I've successfully repaired four or five drives in this manner. Steve

KS10 (PDP-10) FPGA Status

by radioengr＠gmail.com

There has been significant progress over the Holidays. All the Basic Instruction Diagnostics now execute successfully. Many of the Advanced Instruction Diagnostics also execute successfully - the Advanced Diagnostics that fail, do so because they require support from the Diagnostic Monitor (SMMON) which is not 'linked in' at this time. I have a design roughed-in for a RH-11 Massbus Controller supporting 8 RP06 Disk Drives. All 8 RP06s disks use a single 8GB Secure Digital (SD) Disk Card for media. There is still a lot to do before the Disk IO will be ready to test. I've also implemented an DZ-11 8-port Terminal Multiplexer, and the KS10-Backplane-to-Unibus IO Bridges. If anyone knows where to find the KS10 DZ-11 Diagnostic DSDZA Source code, please contact me. I have verified that I can use the same 'bits-on-disk' format as SIMH. That will allow the KS10 FPGA to use any of the freely available disk images without modification. You also should be able to use the SIMH Tape IO facilities to create your own disk images.

CFFA3000 and Apple III?

by wheagy＠gmail.com

A quick update on my Apple III. I used the BNK, ADR and Exp/Got info from the Apple III RAM test to narrow down the bad RAM chip. I replaced it with one from an Apple II and it worked. The RAM test completes successfully, but it does do one odd thing shown in this pic... http://i.imgur.com/VP98h.jpg Row 7 gets dashes across it during the second pass and all subsequent passes. The test, however, continues normally. I ran it over 10 passes with no problems. Any ideas what the dashes mean? On the downside, my III still doesn't boot. It does pretty much what it did before. WIth an SOS disk in the drive, it spins for about 3 seconds, then nothing. The demo disk does the same thing. The III+ diagnostic disk that used to boot, doesn't boot anymore and fails with an IO error message. This makes me think again that there may be a floppy drive issue. Is the drive calibration method that was mentioned previously the one that is outlined in the Sun Remarketing Do It Yourself Guide for adjusting Apple III drive speed...that uses a 60 Hz light source? If so, I guess that's my next task to try to revive this machine. Thanks, Win

DEC LAVC SCA Specification

by robert.jarratt＠ntlworld.com

I have been trying to find if there is a published spec for the DEC LAVC SCA protocol. The reason I want to find it is that I want to see if I can work out why my MicroVAX II is failing the net boot, it times out after a while and falls out of the cluster. I suspect I have a hardware problem, but would like to use a packet sniffer to work out what is going on. Is such a document available? Regards Rob
