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

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

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. For complete information, please visit: http://www.techtravels.org/KS10FPGA/ Rob Doyle doyle (at) cox (dot) net

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

FW: 68360 - status

by LYNCHAJ＠YAHOO.COM

Hi, If there are any builders who would like to participate in the MC68040 SBC project please let me know. We are working on an intermediate project at the moment based on the MC68360 which is the integrating glue for the MC68040 SBC. The MC68360 is the all-important piece that has to work well before even considering the MC68040 CPU since it is a standalone processor by itself. There are some spare MC68360 P1 PCBs remaining (see the excerpted status update below) and the basic board seems to be working. It is booting from the ROM and partially initializing. More work is underway to further initialize the MC68360 chip subsystems like timers, UARTs, etc. The plan is to integrate a Propeller based IO subsystem (VGA display, PS/2 keyboard, microSD mass storage), DRAM, and Flash memories to the final SBC. This is an ambitious project and will take quite a bit of time so if there are any experienced MC68040/MC68360 builders that would like to contribute your help would be greatly appreciated. Additional information is posted below. http://n8vem-sbc.pbworks.com/w/browse/#view=ViewFolder&param=68040%20SBC http://n8vem-sbc.pbworks.com/w/browse/#view=ViewFolder&param=MC68360%20P1 Similar to other N8VEM home brew computing project boards these are free/open source designs including hardware, software, and other related information. Please contact me at LYNCHAJ at YAHOO.COM if interested. Thanks and have a nice day! Andrew Lynch -----Original Message----- [snip] To: Andrew Lynch Subject: Re: 68360 - status Hi Andrew! I have made quite a bit of progress - if you look at the steps on 9-13 through 9-16 of the User Manual I am at step 11 so I only have a few steps left. [snip] BTW - I have I think 4 extra boards (the other place sent me boards anyways) so if people want to join in the fun, I can forward you the boards. We are also going to have to chat on how we proceed from here - looking at the stuff Alan sent and other errata - the 68040 is not going to be a "glue less" implementation and will require some GALS or a CPLD.

SCSI to IDE/SD bridge board project

by LYNCHAJ＠YAHOO.COM

Hi Recently there has been a bit of renewed interest and an uptick in activity in the N8VEM SCSI to IDE/SD bridge board project. http://n8vem-sbc.pbworks.com/w/browse/#view=ViewFolder <http://n8vem-sbc.pbworks.com/w/browse/#view=ViewFolder&param=SCSI%20to%20ID E%2FSD%20prototypes> &param=SCSI%20to%20IDE%2FSD%20prototypes There are still some prototype boards available in case anyone would like to help bring this project to completion. The prototype boards do work in that they are booting the debug monitor (Zapple) and the IO subsystems are checking out. What we need is the programming to make the Z53C80 SCSI controller work in target mode with the SCSI host mode controller. This board project will be free/open source with software, hardware, and other design information posted to the public. Please contact me if you are interested in helping out at LYNCHAJ at YAHOO.COM I realize there are many ways to accomplish this task and the Z80 based embedded controller board is but one. There may be other valid approaches however none are free/open source projects AFAIK. Please post a link if I am mistaken. Any lessons learned and/or design information from this project could be readily applied to a follow-on project potentially using different technologies. However I think it is important to get this first step working before moving on to another design. I am willing to support a follow-on design once we get this one working properly. I believe with a quick Z80 (8 MHz or greater) there should be sufficient through put for most SCSI-1 applications. It will never be a "speed demon" but the older vintage/classic/hobbyist SCSI-1 machines probably don't need one either. Many of the aging SCSI-1 machines are going to go "offline" forever if the supply of SCSI-1 drives dries up. Thanks in advance for your consideration. Have a nice day! Andrew Lynch

Identifying power connector for GRiD laptop

by derschjo＠gmail.com

Hi all -- Picked up an interesting old "laptop" -- a GRiDCase 1537E. This is a Tempest-hardened devicewith (I believe) a 386 processor. Also looks to have an electroluminescent display. Inside there isn't a single exposed wire or circuit board, so any debugging I might need to dowill be a fun prospect. At any rate, I didn't get the AC adapter with this thing and it's got an odd connector that I'm not familiar with. See here: http://yahozna.dyndns.org/scratch/gridcase/1537/power.png The connector's abit over 1cm in diameter with three oddly-spaced pins. I'dlike to build areplacement assuming I can work out the pinouts (and find/fabricate a mating connector). Anyone know anything about this machine?Any ideas where to find such a connector? Thanks, Josh

No, not that I remember. Are you talking about someone at Meridian? I didn't work there, I worked for AIRS (Automated Information Retrieval Systems) back then. The guy I worked for was named Eldon. I collaborated with (over the phone) a a guy named Wink at Meridian. What was his last name? Like the chipmunk guy I think... Seville? We were one of Meridian's first customers on the East Coast. Wink wrote their custom drivers. Before mscdex, before Yellow Book, back in the dark days. Bill S.

8 bit virii

by tshoppa＠wmata.com

geneb writes: > As far as I know, there was never a known instance of a virus on an 8 bit machine. "Elk Cloner" for the Apple II, according to Rich Skrenta went wild in 1982. Was written up very nicely in a Scientific American article in March 1985 (good enough that I wrote a "me too" virus based on the article.) Very similar to what a IBM-PC guy would call "a boot sector virus" (although really there's a little more than that in either the Apple II or PC-clone cases.) It would be interesting if any of the Apple II disk image archives, have Elk Cloner or lookalikes in them. I once thought about automating such a search as an addition over the effort to index the Apple II disk images floating around on the net. Haven't thought of that in, oh, nearly 20 years now!!! Tim.

3.5 alignment? (~~opps, not 3.25!)

by pinball＠telus.net

Looking to test/service/align a number (10 or so) of double-sided double-density 3.5 floppy drives and hoping there is someone here in Canada who has the alignment discs that I could borrow/buy. These are for setting up some of my older computerized microprocessor test gear (Fluke mostly)... Suggestions on aligning are also greatly appreciated! Thanks!

NASA computers circa 1969

rtVAX 300.

by holm＠freibergnet.de

Next time I'll get this: http://www.tiffe.de/images/11122012114.jpg Is anything known about this board here (Manufacturer, Adresses, Switch settings and so on)? Looks to me like an VAX upgrade to an PC with onboard SCSI, Ethernet and Serial Ports... I have 2 2nd rtVAX board here from a friend, this is a VME CPU with SCSI on board. I should look if I could get it to boot.. Any hints welcome, Holm -- Technik Service u.

PDP-8 Paper Tape Reader Emulator

by michael.99.thompson＠gmail.com

With lots of help from members of this forum and other friends I made a high-speed paper tape reader emulator from a wire-wrapped interface board and an Emcraft SmartFusion FPGA evaluation board. The interface board plugs onto the Posibus interface slots in a PDP-8/L. I loaded Focal from a BIN paper tape image into a PDP-8/L in about 2 seconds. That equates to about 3000 characters per second. I put some details about the project here: https://sites.google.com/a/ricomputermuseum.org/home/Home/equipment/pdp-8-l… I will make an expanded version of the interface board and change to the Emcraft SOM FPGA board. That will give me enough I/O pins to emulate just about any peripheral that you can connect to the Posibus. It would be possible to make an interface board for the Negibus so that the peripheral emulator could be used on earlier PDP-8 systems. -- Michael Thompson

EZ-SCSI 4.1

by sales＠elecplus.com

For those of you trying to deal with old Adaptec cards, like the AHA-15xx series, EZ-SCSI is needed, since they have no on-board controls, others than a few jumpers. The software came with some drives, but is hard to locate now. You can download the entire program here: ftp://82.199.101.173/install/System/Driverzzz/CD/SCSI/Adaptec%20EZ-SCSI%204. 01a%20-%201 Documentation is here: http://www.adaptec.com/en-us/support/_eol/scsi_sw/ez-scsi_4.01/install_sw/ez scsi_401_readme.htm?nc=/en-us/support/_eol/scsi_sw/ez-scsi_4.01/install_sw/e zscsi_401_readme.htm According to Adaptec, this will not work with anything higher than Win95 or NT, but you can use it in DOS or 3.1 Enjoy!

CFFA3000 and Apple III?

by wheagy＠gmail.com

Good idea. Thanks for the plan. I'll give that a try. ---- And why would he do it with such a great memory board he has? It is just a matter of finding one (socketed) memory chip! :oD You can do a simple troubleshooting to discover which chip is defective without having 4164s there: Number chips from 1 to 16: 1 2 3 4 5 6 7 8 9 10 11 12 13 14 15 16 Now swap the first and last (1 and 16) and run the memory test No problems? swap 2 and 15, and run the memory test No problems, swap 3 and 14 and so on When you find that the last swap changed the position of memory error, you know that one of these two chips has problems :o) Since you said you have a //e, you can find 4164 as the main board memories of the //e.

IBM Displaywriter software?

by aek＠bitsavers.org

Is there an image archive of software for the Displaywriter somewhere? Someone donated one to the Computer History Museum recently, and I went through our archives and have only come up with a bunch of versions of the CE disk and a single TEXT PACK 1 diskette. I did image what we have, and put it up under http://bitsavers.org/bits/IBM/Displaywriter One thing I discovered was you HAVE to degauss the floppy before cloning the CE diskette. It expects tracks 37, 41 and 43 to be blank or it hangs.
