Hi, I thought I sent this to the full list but Zane told me that I only sent it to the auction notification list. So here it is again. A friend of mine found a DG Nova III in a local scrap yard. He says that it looks complete and in good shape and that it doesn't look like it's been rained on yet. He says that it's in two ~ 5' tall cabinets and has a reel to reel tape drive and four terminals. Anyone want to rescue this? I DO NOT have room/time/money to rescue and/or to ship it. If you want it, come and get it. It's located in Sanford, Florida. Joe

Are tatty boxes worth keeping?

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.

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

...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!

Information Please -- HP 13037D Storage Control Unit

by rigdonj＠intellistar.net

Hi, I went scrounging again today and came home with a HP 13037D Storage Control Unit Option 100. It's dated 1984 but the only reference that I could find to it is in the 1977 HP catalog. It lists the 13037A and says that it's a micro-processor based controller that offers a high level interface that simplifies the design of the CPU I/O card. And that multiple drives and CPUs may be connected to the SCU. Big whoppee! What does that mean? Can anyone tell me more about it? I assume that it's for the old HP MAC (Multiple Access Controller) interface. It has an HP-IB port and several cables that have card edge connectors. I doubt that I need it so if anyone has a need for it contact me directly. Joe

Information Please -- HP 13037D Storage Control Unit

by jlwest＠tseinc.com

You wrote... > I went scrounging again today and came home with a HP 13037D Storage >Control Unit Option 100 Off the top of my head without checking the manuals for accuracy..... The 13037 was HP's bid to get away from having a different controller in the backplane for each different drive. Previous disc interfaces were particular to fixed head, moving head, drum, etc. In addition, the interfaces in the card cage always took more than one slot as I recall. There is a 13037A, B, and C that I know about, I have nothing that refers to the D model. With the 13037, one interface card goes in the card cage. Cables go from this to a rack mount box (about 5 inches tall, about 28 inches deep). Inside this rackmount box was a separate microprocessor board and additional disc interfaces. The drives in turn were connected to the rackmount box. The particular features of the 13037 stuff was that more than one system could be connected to the rackmount microprocessor, but mainly different types of discs could be connected. The 13037B could do 7905, 7906, and 7920 drives. The 13037C added the capability to do both MAC and HP-IB drives. I have it on good word that the A and B models were junk (comparatively), and that the C model was the "one to get". I might have a spare manual on the 13037, I'll have to check. I do have a 13037C under refurb at the moment. Regards, jay West

List spam again

by kyrrin＠bluefeathertech.com

Regarding that spam from the fellow selling computer parts... First, let me say that I've been actively fighting spam since I first got a dial-up 'net account in 1994. I've seen a lot of spams, and I've gotten to where I can usually tell when someone may have made an honest error in judgment, as far as advertising their new business, vs. actually doing intentional spam. The spam from Mr. Holtzclaw had the feel of an honest error to it. Here are the actions I've taken. 1). I have traced back the spam to its source, and notified the ISP involved (jaxn.com was indeed the source). Their AUP specifically prohibits spamming, so I would not be surprised if Mr. Holtzclaw starts looking for a new provider very soon. 2). I have sent a note to Mr. Holtzclaw, something I almost never do, explaining -- POLITELY -- about spam, about what he did, and where to find web resources that explain what spam is and why it is a Bad Thing. I'll keep the group updated with any responses I receive. Oh, and I also sent a message to our (perhaps justifiably) overzealous member who wanted to fire off a DoS attack on the responsible mail server. I have asked him not to do so, as fighting abuse with more abuse never gets anything done. Onward we go...! -=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=- Bruce Lane, Owner and head honcho, Blue Feather Technologies http://www.bluefeathertech.com // E-mail: kyrrin(a)bluefeathertech.com Amateur Radio: WD6EOS since Dec.

HP TSB internals

by jlwest＠tseinc.com

No Sellam, no one took the time to reverse engineer TSB.... This manual is called 2000E IMS (Internals Maintenance Specification). It was written by HP, and I'm pretty certain it was used to train new programmers who were to work on the TSB code itself. It's just way too detailed (and most of it printed too nicely) to be someone just doing some reverse engineering. I'll probably get to scanning a few parts of it in next week. Cheers! Jay West

If this gets too involved, I'll simply have to suffer through doing it from the parallel port on the PC, but I already have some code written many years ago (in BASIC) which does the job nicely, and I'll probably never use it again.

The code was written for an S-100 box I used back in the '80's which ran a 12MHz (hand-picked) CPU together with some fast SRAMS. I don't want to fire up the S-100 stuff right now, and the AMPRO provides sufficient packaging to allow me to install a mezzanine board on the processor socket. My HDC adapter sits there anyway, and the code is on that drive. It steps through the process of troubleshooting the logic on Shugart 800/801 boards, Siemens 100-8's, and a few others I don't have to deal with today. The timing probably isn't even that critical, but I prefer to handle the job this way since I've given away the hardware I previously used. The thing I have to build is just a port in and a port out, to monitor and control the signals to/from the drive without having to read and write. This also allows monitoring of the signals at various test points in the circuit without having to use the 'scope, which only does half the job. > ><'A' type peripherals, provided I switch the clock to 4MHz each time I see a ><IORQ* or an (M1* & I/O*) or a RETI on the data bus during M1*, resetting th ><higher speed on the next M1*. > >there is a wait line for this kind of stuff.

New arrival... (s)? (pt. II)

by jimw＠agora.rdrop.com

...a few days ago I scribbled... > ...And hopefully (if Murphy does not interfere) by the end of the weekend yet another > item will be struck from the list! Stay Tuned!! Well, it happened! Ducking 'Murphy' vibes all the way, (deal was a bit shaky right up until the end) but another one falls from the list! An early Altair 680 with full front panel joined the collection tonight. No docs or software (see a request coming on?), but it is pretty good shape and appears to be reasonably coherent.

by vaxman＠uswest.net

Hi Don and other ListErs, I have been working on a similiar problem... I have the original DEC distributions for a few things (including Ultrix 3.1, looking for UWS 3.0), and I want to make archival copies of them... I discovered the TK-50Z (both FA and GA) will work with FreeBSD and an old Adaptec SCSI controller. This allows me to read (and copy) the TK50 onto my PCs hard disk, but I haven't quite got the format right to write a new tape (still playing with file marks)... NOTE: I tried a 2940 and a 1535 and neither of them worked. I was successful with a AHA-1542B scsi adapter. I also have a SCSI adapter for my uVAX II, and have copied tapes >from TK50 to 4mm DAT, but it seems quite a waste to put 95MB on a 4GB tape. Finally, if none of these options appeal to you (and you don't have other success), I have a uVAX II with a TK70, TK50, SCSI adapter for the 4mm DAT, and a 9-track tape drive, and can copy them for you (contact me off list for this). Laters, clint PS My 11/750 is up and running!!! The dead power supply turned out to be two pins shorted on the backplane... Sometimes my debugging skills leave something to be desired... PPS What is a Fujitsu Eagle worth used? I am going to upgrade the 11/750 to a SCSI controller and 3.5" drive as soon as I get two nickles to rub together :) > >I have been tinkering around with my VaxStation 2000 and a couple of >TK-50Zs that I have.

HP Timeshare BASIC OS - cool find!

by jlwest＠tseinc.com

I got a bit of spare time to go through some of the documentation I received with my recent HP 2100 systems. I have found an incredible item in there! The notebook is about 3 inches thick. It is a training manual along with hundreds of pages of handwritten notes on the Internals of HP Timeshare BASIC. Not only does it describe all the byte by byte formats of OS tapes, SLEEP and HIB tapes, OS and user disc layouts on a sector by sector basis, but it also has diagrams of every data structure in RAM and on disc related to the internal operation of the OS. In addition, it even has over a hundred pages of detailed flowcharts on how every system module operates. These are not general flowcharts, but flowcharts written from a datastructure standpoint. These flowcharts give blow by blow descriptions of exactly what fields in every data structure are modified when that module runs and why. Not just the system modules, but every BASIC statement, user command, operator command, etc all the way down to the scheduler, mux driver, etc. With this information, one could very easily (albeit time consuming) write TSB from scratch. I'll have to scan all this and put it online for interested parties! Jay West

Syquest Sydos Puma 88

by musicman38＠mindspring.com

Still trying to find a DOS driver to use my newly acquired Sydos Puma 88 Drive I found this information of Syquest's web site but was not able to find the drivers they mentioned. Does anyone have one of these units or know where I can find the drivers and manuals ? Thanks.. Phil http://www.syquest.com/support/tb8010.html TB8010 - SyDOS PUMA Subsystems The SyDOS PUMA 44 and 88 MB units were produced for the PC marketplace by the SyDOS division of SyQuest. SyDOS was a division of SyQuest located in Florida. Its function was to provide products for the DOS marketplace. Some of its parallel port products used the SyQuest SQ555 and SQ5110 SCSI drives in a subsystem with a parallel to SCSI adapter card, power supply, etc. This hardware interface card with the SyQuest drivers installed the SQ drives into the DOS 3.0 through 6.22 operating systems. The manufacturer of the hardware PP to SCSI interface is no longer in business. With the release of Win'95 requiring some additional hardware interface support, the PUMA units can not be updated to be Win'95 compliant. This additional hardware requirement makes the update to Win'95 real mode drivers unavailable. On some systems the PAR driver can install the PUMA unit in the DOS Compatibility mode. This greatly depends on the hardware in your PC system. The PUMA unit was developed before the release of Win'95 and the ECP/EPP hardware. Some older 486 class PCs should be able to install the PUMA units in the DOS Compatibility mode. The newer the PC, the less likely the installation will be successful. SyQuest drivers, utilities, and readme files are in our download section or ftp.syquest.com. The PUMA1.ZIP and PUMA2.ZIP files are the two files containing the driver and utilities for these units. You must use PKUNZIP to extract the driver and utilities.

IBM/XT Y2K Compliancy

by peter.pachla＠vectrex.freeserve.co.uk

Hi Roger, >Are the IBM/XT, IBM/AT and PS/2 computers hardware Y2K >compliant? According to a recent thread in the PS/2 newsgroup, all PS/2s should be broadly Y2K compliant, though some machines may need their times resetting on 1/1/2000 depending on the OS they're running. PC/XT class machines generally have no clock hardware in them as standard. DOS/whatever simply use a regular interrupt to update a software clock, so you need to know if the OS you're using is compliant. All AT class machines have a clock chip inside, a 14818 (or something similar, I forget), or an emulation of one. The chip only stores the last two digits on the year, so it will correctly roll over to "00" for "2000". However, what your operating system will make of that is another matter.... In each case, it all boils down to your OS. The easiest way to find out if it's compatible is to set your clock to a few minutes before midnight, December 31st and wait and see what happens when the time rolls over past midnight.

Novel/Eagle NE1000 & NE2000 ethernet cards (& others)

by jeff.kaneko＠juno.com

3Com's 3C300 was their 1st PeeCee NIC, it was a big card, contrast to their later 503's and 509's which had a much higher level of integration. I'm told 3Com's very first product was a MultiBUS NIC (of which I have two). Can't seem to find the docs for it, though. OKay, for 100 bonus (bogus?) points: What were the three Com's of 3Com?

Novel/Eagle NE1000 & NE2000 ethernet cards (& others)

by mark_k＠iname.com

Hi, Recently I picked up a load of Ethernet cards (some nicer PCI bus mastering ones -- excellent for Linux etc. -- are for sale, btw). NE1000 & NE2000 --------------- Amongst these are what I believe to be Novell/Eagle Technology NE1000 and NE2000 cards. Now, I have found jumper info for these two, and got them to work on a simple two-computer peer-to-peer Windows 95 network. The NE2000 works fine. The NE1000 seems to also, except when trying to copy a 40MB file to the computer which contains the NE1000, it hangs part-way through (this happens every time). Either this is a fault, or simply a deficiency -- perhaps the other computer is sending data too fast for the NE1000 to keep up, and it gets confused? Anyway, I'd like to get the official/original drivers, documentation and diagnostic programs for these cards. I looked at http://www.novell.com/, but there seemed to be nothing there. Eagle Technology don't seem to exist any more, or don't have a web site. There appeared to be some NE1000/2000 stuff at ftp.microdyne.com, but it turns out that this is for the NE2000+, whatever that is. Does anyone know if there is some other Novell web or FTP site that has info on their ethernet cards? Here's some info about my two cards. NE1000: 8-bit ISA card. Novell warranty label has date code 2789. Text silk-screened on PCB reads BD.# 738-160-001 REV. C ASSY.# 810-160-001 REV. C NE2000: Warranty label on rear has data code 5092, says manufactured by Eagle Technology. Text silk-screened on PCB reads BD.# 738-149-002 REV. C ASSY.# 810-149-002 REV. C IBM Ethernet card FRU 48G7170 ----------------------------- I also got a couple of these. They seem quite nice, having BNC, RJ45 and AUI connectors plus two indicator LEDs. A label on the PCB reads FRU 48G7170. Both cards have boot ROMs fitted, on which a label reads 60G3312. If anyone need to make a boot ROM for this type of card, I have dumped the data from them. This card is configured using a DOS setup program. The only jumper on the card is labelled J5. Does anyone know what the purpose of the J5 jumper is? Oldest PC ethernet cards? ------------------------- Drifting slightly back on topic, which companies made the earliest ethernet cards for PCs? How much did they originally cost? -- Mark

A pointer to classiccmp from an .epa.gov site

by svs＠ropnet.ru

G'day, While searching for existing searchable archives of classiccmp, I found <URL:http://epainotes1.rtpnc.epa.gov:7777/r10/owcm.nsf/recycle/pcrecycle>: [...] Computers and electronic equipment that still work, but are obsolete, may be suitable for reuse. Check with local schools, training institutions, or non-profit organizations to find out if they accept donations of this type of equipment, or use the list of recycling options to obtain the names of organizations that will repair, consolidate, or reassemble the equipment before donating or selling it. There are a growing number of hobbyists interested in very old computers. Any machine that is "so obsolete that it can't be reused" may actually be of great interest, and potentially worth much more than its value in scrap metal. Older is better here.
