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.

VaxStation 2000 and TK-50Zs

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?

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.

Olivetti wide carriage daisywheel printer (from S100 based WP system) Star NB-15 wide carriage 24-pin printer Princeton Graphics EGA monitor (x2) Nixdorf VDU Televideo 950 VDU (x2) Zenith Z89 VDU The latter items would really only be good for spares, e.g. the Star Printer needs a new printhead, the Z89 is missing the video board, the TV-950s won't communicate with their keyboards, but it's all available for the cost of coming to get it. I'd rather not dump this stuff in a skip but that's where it's all headed and soon if someone doesn't take it away. I'm located in Birmingham, email me directly if interested.

Tempest Macintosh pictures

by dastar＠ncal.verio.com

Here are some photos I took of my tempest Macintosh. There's nothing particularly extraordinary about this machine unless you look at the details. I didn't get any photos of the inside because this thing is a total bitch to take apart. It took me about half an hour just to get the back cover off when I first cracked it open. It's not because of the hex screws or anything like that. This thing has a metal housing built into the case, with a bunch of finely machined screws holding everything together. To take the back cover off requires undoing more than just the standard hex screws. The nubs on the I/O connectors also have to be removed. Anyway... Back side of the unit. Note the toggle switch which replaces the old on/off switch. The knob below it is a fuse holder. Note the power cord is now permanently attached to the unit. The back I/O connector panel has been cutout and then re-attached with new cutouts to reduce the holes where emissions could escape. This panel is laced with a metal mesh. A CRT brightness control has been added to the left of the battery holder (the battery cover is missing). The small cover screwed into the case on the left side is where the slot for the security device used to be. http://www.siconic.com/crap/tempmac1.jpg Front of the machine. Nothing unusual except for the square slot cutout where the keyboard RJ14 connector used to be. A close-up view is coming up to show how the keyboard attaches. http://www.siconic.com/crap/tempmac2.jpg Side view. Guess what? That slot is another Sony 3.5" floppy that has been installed internally. The slot has been manually cutout. http://www.siconic.com/crap/tempmac3.jpg The backside label enlarged so you can read it. The manufacturer (or rather re-manufacturer) is Systematics General Corporation of Sterling, Virginia (a wholly owned subsidiary of Atlantic Research Corporation). I mentioned this on the list when I first got this unit sometime in 1997 I believe (or early in 1998). I paid $10 for it. http://www.siconic.com/crap/tempmac4.jpg A close-up of the keyboard connector. It attaches to the unit via the modular plug. Then the panel screws on to the front of the machine. The duct tape looking piece of material is a metallic mesh that prevents leakage of emissions. Note the brass gasket attaching the shielded cable to the keyboard housing. The metal box on the back covers the old keyboard connector. http://www.siconic.com/crap/tempmac5.jpg Sellam Alternate e-mail: dastar(a)siconic.com ------------------------------------------------------------------------------ Don't rub the lamp if you don't want the genie to come out.

Wang VS7110 System FREE

by jpl15＠netcom.com

An update on the Wang system I rescued from Certain Death.. I found a good portion of the manuals today while on an un-related mission to the warehouse. I was walking past 2-story-high pallet racks full of boxes of paper files, and a Wang binder caught my eye.. sure enough, what appears to be the operations documentation, including much custom work by the sysop(s) was in an open box. I now have it with the machine itself. Anyone on (or off) the List who is interested in acquiring this taken-out-of-service 7110 system... contact me via e-mail. It seriously wants a loving home and some 220-1 ph to eat. FREE FREE FREE Cheers John

New arrival... (s)?

by jimw＠agora.rdrop.com

Well, it just goes to prove once again that not all of the rocks have been turned over. Based on a recent tip from another collector, I've managed to knock one more item off of the Computer Garage 'Most Wanted' list with the arrival of an IMSAI dual floppy disk sub-system. No software or docs with it, but that just adds to the adventure! B^} Something about the unit suggests that the previous owner ran CP/M on it, but as to just what that clue is I will leave without explaination. (that way you have to look at the pictures) <G> The images are immediately post-unpacking, so the unit has not been cleaned, checked out, or powered up... but its here!!! Hmmm... I wonder if there is a copy of IMSDOS buried around here somewhere??? <BG> And hopefully (if Murphy does not interfere) by the end of the weekend yet another item will be struck from the list! Stay Tuned!! -jim --- jimw(a)computergarage.org The Computer Garage - http://www.computergarage.org Computer Garage Fax - (503) 646-0174

IBM/XT Y2K Compliancy

by elvey＠hal.com

Hi A while back, I had to come up with a clock system that would work with a simple clock chip that only went up to months but not years. The machine did have some other non-volitile memory so here is how I delt with it. I had what I called a half year counter. If when the machine turned on, the clock chip thought it was in early half of the year and the RAM said it was in the last half, I'd update the year and reset the bit. The only requirement here was that the machine had to be turned on at least once every 6 months or soemone had to reset the time. Why they couldn't have done something as simple as this for the century, I don't know. Dwight

IBM/XT Y2K Compliancy

I have a (yea, nice, broad, vague) question... Are the IBM/XT, IBM/AT and PS/2 computers hardware Y2K compliant? I'm not really into the old Clone machines, and don't really know... (and personally I couldn't care -- but we had a customer ask about them and I could really use an answer...) Anyway, there are many folks on this list more intelligent than me, and figured this is the quickest way I could get an intelligent answer to my foolish question. ;-) If no-one else is interested in this discussion, I'd be happy to take it to email only. Thanks for any help y'all can provide, Roger "Merch" Merchberger -- Roger "Merch" Merchberger --- sysadmin, Iceberg Computers Recycling is good, right??? Ok, so I'll recycle an old .sig.

No software was available for the cardset. They also suggested that I call back later (when someone with a technical background would be available...) If I find out more, I'll drop the list a note...

I need the following word defined/confirmed.... Hacker According to my dictionary, 'hack' means "to chop with exceptional force", "a violent cough", or "a horse let out out for common hire"... Same dictionary... 'hacker' "one who hacks" (no - really?....), or 'a person who is inexperienced or unskilled at a particular activity' example is "A Polo hacker". I wonder which antique store I bought that dictionary from... :) Here's my definition: "One who adapts an existing piece of computer (or other type) of hardware to suit one's needs or to improve it without instruction from the original manufacturer." I also thought that the people who screwed with viruses and software and such were "crackers" (which my dictionary describes as a 'dry, thin bread substance"). Am I right? or am I just blowing smoke?

RT-11 DU: Handler Question

by healyzh＠aracnet.com

OK, as long as I don't run into any unforseen trouble that keeps me from having time, I plan on installing RT-11 on a large disk in the next few days. However, I won't be using the nice WQESD ESDI controller that I've got that makes partitioning disks easy. So I want to make sure I understand how partitioning works under RT-11. If I'm reading the manuals correctly I would first boot off of my RL02 pack and do the following .INIT/BADBLOCKS DU0: then .SQUEEZE/OUTPUT=DU0: DL1: .COPY/BOOT DL1:RT11FB.SYS DU0: and then boot the system from DU0: So far that's pretty straight forward, and except for using SQUEEZE to copy the distribution, pretty much the way I got it from RX50 to RL02. Now then since I'll want to use more than just the first 30Mb of the Hard Drive, I'll need to set up partitions. Do I do this prior to initializing DU0: or after booting from a freshly installed DU0:? I realize the command to do the partitioning is: .SET DU0 UNIT=0,PORT=0,PART=0 .SET DU1 UNIT=0,PORT=0,PART=1 .SET DU2 UNIT=0,PORT=0,PART=2 .SET DU3 UNIT=0,PORT=0,PART=3 Also I assume that a partition has to be 65,535 blocks, but does the last one have to be that, or will it simply be however much space is left?

RX02 Repair

by steve.lubbers＠barco.com

Tony, Thanks for the suggestions, I'll see what I can see tonight. I have a copy of the RX02 Field Maintenance Print sets, so I can follow what you are describing. I don't think I have a spare 2102, but could get one easy enough. I didn't think of the load/dump sector buffer approach. That sounds like I good idea! Any programming help you have would be great!

186 (was: CompuGraphics Question)

by edick＠idcomm.com

The only 'xt-type machine I have kept since the "old days" when such things were common, is a "Challenger" motherboard (made ??? but sold through an outfit in Boston) which was a 10MHz '186 as the processor in the 'XT architecture. It had some 16-bit slots, though I never checked them out for functionality, since there were few devices suitable for that. Since the integrated peripherals could be relocated to an "out of the way" location that was almost the first thing that happened in the ROM code. I've held onto one just in case I ever needed to develop something for a '186 again. That and the '188 and the NEC V-40 and V-50 were my favorites of the time. I liked those built-in memory selects that allowed you to build a system with almost no glue logic.

Longshot here but ... Anyone happen to have the software for this guy? Of course Dayna was of no use (esp now that they've been sucked up by Inhel). Also pinouts for the connecting serial cable would be nice, though I believe it just uses a standard (for the early Macs) serial cable. TIA George

suggestions on backplane cleaning? (or, HP2100 continued)

by jlwest＠tseinc.com

One major problem with my 2100A has been solved (sort of). I had a card that wouldn't work properly in a particular slot, finally got the bright idea to move it to a different slot (I'm using polled mode, not interrupt, so this is possible). The card works great. Problem solved? No..... In the troubleshooting process I noticed a few slots that no cards would quite work right in. I checked the back of the backplane (it is a hand-wired backplane), no loose wires, etc. After very close inspection of the backplane slots, I determined the problem is the contacts are dirty/corroded/whatever. I tried the best I could to clean the contacts inside the slot, but this is virtually impossible. I also cleaned the card edge with an eraser just to be sure. Bingo - card now works fine but only in the cleaned slot (or one that worked previously). So, given that it's a delicate hand-wired backplane, does anyone have any magic tricks for how to clean the gold contacts inside of the backplane edge card connectors? I'm afraid to experiment and looking for wisdom... :) Thanks! Jay West

I've been persuaded (by a couple of the guys who worked on the Boca-Raton development of the PC) that Intel provided them with a prototype board used in the development of the '188 and that it became the hardware model for the PC motherboard. It's hard to dispute, considering that the timers, DMAC's, etc would have been prototyped using "real" hardware. That would also explain some of the stupidity surrounding interrupts on the PC. Not even IBM would have done something so silly as to use positive-going interrupts, except perhaps out of fear that fixing it would break something. They were on a tight schedule, you know.

The '18x series was the first, and possibly last, evidence I ever saw that Intel could build something fairly sensible. I think the '18x series was designed for military applications, originally. The disk-drive applications I've seen normally use the '188, since they offer byte-wide interfaces up to the EIDE types. It's entirely conceivable that the '186 was used as well. I saw one on a WD ESDI controller for the PC.

My very first 'x86 machine was based on a board called a "Slicer" which later was offered as a two-board system. It had a 6 MHz '186 and enough of those weird stackable memory sockets which allowed you to put two 16-pin RAM packages in what was essentially a single 18-pin site, to accomodate 128K-bytes of the 64K DRAMS. It provided a little serial I/O and little else other than the FDC. The add-on card, which was offered later, had a SCSI port and some parallel I/O (?) It's been a long time, but I think it added another 128K bytes of RAM.

AT/370 and XT/370

Anybody every run across any of these? I don't think the 3270PC was what Mike meant. There was a PC with a couple of boards in it that became a self contained machine running the 370 instruction set. It was intended as a 3270 variant, though - developers would download their code to the PC, debug it on the local processor, and upload the next version, freeing the big machine (of which many companies had only one, after all) for users who wouldn't grab oodles of processor time with an incorrectly terminated loop or whatever. I, like Hans, have never come across one of these, although I heard of them back at IBM in '85 or '86. But I recall a rumour from another source that the 370 emulation was based on the 68000 circuitry but with custom microcode. These machines would run VM but not MVS, I think.

Anybody every run >across any of these? Yes, I can't get at it right now but I picked up an XT/370 a few years ago at a radio rally. Unfortunately the machine had been fairly comprehensively rebuilt with a '286 motherboard and some sort of half height hard drive (despite having a full height "IBM" hard drive front plate on the front). I managed to get the original motherboard (broken expansion connector) and tape streamer out of the guy, but the monitor, keyboard, cards, etc were already gone.... :-( TTFN - Pete. -- Hardware & Software Engineer.

RX02 Repair {Follow Up}

by steve.lubbers＠barco.com

Thanks All for the suggestions I've received so far. To answer a few of the additional questions that cropped up: I've had the drive for about 11 years. About 5 years ago it worked correctly, so I'm assuming that internal switch settings are correct (though I don't have a reference to verify them), and the controller/drive match. I have a huge collection of disks, some marked RX01, some RX02, none will boot. I am currently working with an RX02 disk that was used to boot another PDP-11, then sent to me. I checked that both drive belts are in place, and used a scope on the photo transistor that detects the hole. The drive RPM was correct. tony- This would help >>>There are some things you can try.

Cool IBM PC find

by dastar＠ncal.verio.com

Ok, here's something very cool as far as IBM PC artifacts go. Its an "IBM TPC 4 System Unit" (the model is 4459). Its a tempested PC! Its basically an unfinished PC case inside a bigger case that provides the shielding. The connectors in the back all extend out to the outer shell, which has a metal screen around the connector openings. The power supply power plug connector is a threaded round connector. The power switch is relocated as a radial knob on the front of the chassis. Its got a 5.25" floppy drive and a hard drive (can't wait to see what's on it) enclosed in an inner cage to sheild them. The motherboard is a 256-512K version. The cards inside are pretty standard (I/O, hard drive/floppy interface, expanded memory). Very neat. Anyone ever heard of this?

Hi, >If it has a hard drive, it was probably not used as a Tempest machine. >The TPC I have contains only two floppy drives, and my understanding >is that a tempest machine must have media that can be removed >and cannot have fixed media. I found a bunch of XTs in Tempest casings at a scrapyard in Oxfordshire about 6 years ago. All of these machines had a single 360K floppy, a pair of Bernoulli removable drives and (I think) a tape drive. No fixed media in sight! Didn't find anything other than the machines themselves though, IE no keyboards, monitors. TTFN - Pete. -- Hardware & Software Engineer. Sound Engineer.

paper tape winding - suggestions???!?!

by jlwest＠tseinc.com

Most of the paper tape software that I have is on rolls, not fanfold. So - unlike my nice PDP-8 PC04 that folds paper tape that was just read all nicely on one side..... after reading a tape roll on my HP I have a very large and fragile mess of a tape pile on the floor. I'm sure that many of the inventive folks on the list have come up with interesting ways to re-roll paper tape after it's read (short of the "by hand" route that takes forever). I don't have an electric or manual tape winder, but figured people around here had found some other thing that would do it well. I *THOUGHT* I had found a great solution - one of those old fashioned hand crank drills. I wrap the paper tape tightly aroung the tip (without a bit in it), set it point down on a cushioned chair, turn the crank and viola - my tape rolls up quickly. However, last night as I saw my cherished diagnostic configurator tape slide right into the gears of the drill, I figured I had better ask for other solutions <grin>. Is there something common around a typical house that folks have found works well for winding paper tape rolls? Thanks! Jay West

WAY Off Topic : routing

You wrote... >I believe that ppp0 is the default gateway on my p166. ppp0? I'm a freebsd person myself, not linux, but isn't ppp0 the SLIP/PPP interface over a serial connection?

How can you have an IP address/subnetmask on the interface without getting a network (192.168.1.0) route via your ethernet interface? Since there's no route to the host, just show us the output of a "netstat -rn" (that's a - r n not a -m) on each machine and that will show the problem for sure. Also, in your configuration I would suggest not running any routing daemon (routed, gated, etc.) - they'll just get in the way. Jay West
