The local surplus place has an Alpha available. I know nothing of these machines. It is in a black 4U rackmount case. Front panel door opens to reveal a 3.5 floppy, removable hard drive (which has been removed and disappeared), and a CD drive. Inside the machine are two scsi cards, and a few others I didn't look closely at. There's 256M of ram (all big 32m modules). If anyone is interested, let me know, and let me know what you want me to look for, and I'll go back and look at it closer. If you want it, I'll put you in touch with the guy at the store. They typically let this kind of thing go cheap. Jay

HP loader rom chips

by jwest＠classiccmp.org

Jameco claims to have real Signetics 82S129's in (not substituted parts). These are for the HP 21MX loader roms. They are quoting me $9.95 each for qty 1-10. Anyone know of a better source, or want to go in with me on this? I will probably get about 10. Equivalent parts (that my 29B can program): Monolithic Memories 6301 Harris 7611 Texas Instruments 24S10 Applied Micro Devices 27S21 So maybe someone knows of a source for the above parts that is cheaper.

IBM Record Unit Machines

by ron.hudson＠sbcglobal.net

What were some interesing record unit machines from IBM Card punches: Which IBM card punch had a dial on the upper part of the keyboard? I used one, but I forget what the dial was for. Card Sorters: What is the machine that read card and could add information and print reports, usually programmed with a patch panel? Were there any machines that read cards and wrote to Mag tape? Is there a collection of Information on the Internet about these beasts?

IBM Record Unit....

by ron.hudson＠sbcglobal.net

I had a passing though of writing emulators for the machines found in an old record unit shop, Card Punches - would be something like an editor. Sorters, Collators?, and all the other machines, with text files as card-decks. I have the link on Wikipeadea, it also just gives a gloss overview. I am not finding the detail needed. Never mind, it wasn't important. I'll go on to other things.

[LONGISH] Beware: dealings with Bert Thomas

by dwight.elvey＠amd.com

Hi One thing to consider by both parties is that when communicating over the phone, a lot of one's ability to convey the meaning of what is said is lost. Much of our communications is visual. We watch reactions as we talk. Most people think that they can communicate properly over the phone. It is a big mistake. I have had several times when I'd been misunderstood. It is still interesting that both sides see the interaction from a different perspective. They both need to realize that it was the phone that caused the misunderstanding. It would be truly incorrect for either to judge the other by the responses over the phone. Of course, even more of communications is lost in the form of email. I'm not saying that either side was wrong or right, only that one should be careful when emotions get involved over the phone. They are rarely interpreted correctly, by the other party. By the time they realize that there was a problem, a lot of damage has been done between them.

Altair8800 'kit' - can you identify this stuff?

by william.layer＠comcast.net

Thanks for the info so far.. here are the ugly details on the 'kit'.. Dave wrote: > Btw - if you have an unassembled 8800 - it might be a good idea to keep it that way - I > would think unassembled ones would be more rare than assembled ones. Sorry if I was confusing on this.. I was half-joking when I said 'kit form'; the unit wasn't so much *unassembled* as *disassembled* :) The unit is quite an interesting hodgepodge at the moment.. Here is a better description of what I have: Original 8800 Chassis, with early faceplate - dang I love that old 70's computer typeface! A ding in the white topcover, but overall very nice shape. Display / Control board (rev 1) removed, and showing evidence of a burnout in the lower left, 7400 chip I think. Someone has socketed every chip on the board, with a collection of random colorful sockets. The board shows some small rework with kynar, to fix lost pads/traces on one socket pattern. Needs a couple of switches replaced. Marked "3421K" in black Sharpie. 8080 CPU card (rev 1) removed and showing signs of modification (a mystery chip has been added with glue & kynar), and CPU is missing. Marked "3423K" in black Sharpie. Motherboard replaced with a Processor Tech (?) MB-1 Mainboard - 16 slots. The pullup/pulldown resistors look like they were installed by a small child, and not a gifted one. I will rework this area. Power supply replaced with beefy 8800B power supply, obviously to accomodate all that extra hardware that the motherboard will hold. Large fan is also added, without a grille. Watch your #&!$@ fingers, kid! A card marked "MCT R30 ASSY 105510" (seems like serial or parallel I/O) A card marked "SD Systems VersaFloppy II" (must be the disk controller) A card marked "SD Systems Expandoram II" (must be the memory card, and it's fully populated. No idea what the capacity is) A card marked "SD Systems SBC-200" (has a Z-80A cpu, and what I think is the matching Z-80 buss driver chip. Has 4 ROM sockets, two of which are populated. One is clearly marked 'EDO BIOS'. Also has edge connectors marked serial & parallel I/O. Seems like a multifunction card; CPU, ROM & I/O) A card marked "Signum Systems MICE-48" with a long ribbon cable leading to an emulator probe, bearing an EPROM chip. (It's clearly an In-Circuit Emulator device, my guess is that it was emulating an 8048 or similar) A card marked "Vector 8800V", which is a complete and utter disaster of Kynar and flying components. I wouldn't let this thing near a running system. (seems like a generic breadboard card, which has been built into some form of custom hardware, has a large device marked "Analog Devices 940", and about 12 other chips, plus a pile of discete components) A large dual-floppy drive chassis, blue in color, with 8" drives. Seems like generic Intel hardware of the mid-70's. No obvious markings. A collection of 8" disks, some clearly CP/M based. I'm quite certain that in light of the Z80 card, that this machine was running CP/M until it was taken (or took itself) out of service. A small board marked "John Bell Engineering Phoneme Synthesizer" with a DIP connector, wall-wart power supply, and a few chips including a Votrax SC-01 chip. (Ok, it's clearly a speech synth. Apparently, this thing could talk at one point..) Ok - I think that's pretty much all of it. If anyone can verify / correct me on identification, or provide other info, it would be greatly appreciated. Some of this stuff (like the ICE hardware) might be up for trade. Thanks for all of your time, Bill

Someone has socketed every chip on the board, with a collection of random colorful sockets. The board shows some small rework with kynar, to fix lost pads/traces on one socket pattern. Needs a couple of switches replaced. Marked "3421K" in black Sharpie. Get a schematic and start plaing with it. Like the IMSAI panel, it uses the processor to actually generate the addresses and fetching from the bus. You should check for shorts with an ohm meter before powering up. After powering up, check for anything that is hot. These old TTL parts would run slightly warm but should not be hot. Be ready to remove the power quickly in case of smoke. With power applied, even FR4 will burn if sustained with an electrical arc. There is a schematic and layout on that CD ROM that has many of the schematics and such ( I've seen but don't have it my self ). > >8080 CPU card (rev 1) removed and showing signs of modification (a mystery chip has been added with glue & kynar), and CPU is missing. Marked "3423K" in black Sharpie. The extra chip is most likely to generate the correct status signals for the refresh of the dynamic RAM. The early boards were designed around static RAM systems and it wasn't until later that the status signals were added. The earlier DRAM boards had no standard way of providing these signals so there are several different ways this was done. ---snip--- > >A card marked "MCT R30 ASSY 105510" (seems like serial or parallel I/O) List major IC's? > >A card marked "SD Systems VersaFloppy II" (must be the disk controller) Will most likely only work with the Z80 processor board. The 8080 was a little on the slow side to handle the disk transfers. Most 8080 systems used a DMA interface for disk drives. I did look at some tricky software that I believe would have worked on a 8080 but it required transfering 4 bytes at a time. It has been some time since I looked at doing that so I'm not much help now. I think the main thing was that after the controller gave the status, you had something like 13 uSec to read the data or it was lost. > >A card marked "SD Systems Expandoram II" (must be the memory card, and it's fully populated. No idea what the capacity is) It depends on which chips are there. If it has the four banks of 16K chips, you have 64K. It could also be populated with 18K or 4K chips but that is unlikely as it came out just when the 16K chips were getting available. See my note above about the refresh signals. > >A card marked "SD Systems SBC-200" (has a Z-80A cpu, and what I think is the matching Z-80 buss driver chip.

It could be a voltage converter as well. They made many discrete circuit instrument amplifiers that had especially low offset inputs. I would get this was an analog board of some type. ---snip--- It looks like a good project. Later Dwight

[LONGISH] Beware: dealings with Bert Thomas

by waltje＠pdp11.nl

Hi all, Today is a sad one, as I had to part with someone I considered a friend, a new collector, and recent addition to the CCtalk community. Bert had trouble with getting his PDP-11/34 to work (as we have all been reading here), and, a while ago, I offered him to have a look at it. We got together, and I was able to fix the system. Took a while, but hey, that's OK. I did mention to him I just acquired a new system, and needed to have it moved to my place. To return my favor, Bert offered to move my system, as he had a van available, which makes it a lot easier than using my car. Great deal! The selling party and Bert were put in contact, so they could agree on a date and such. And that's the last thing I heard about it.. until I got curious, and contacted the seller if something had gone wrong.. I _am_ out of the area and country a lot, so could have missed something. Nope, everything went as planned, the seller replied - Bert had picked up the system that saturday morning, and all was well. He did mention that Bert said that since he picked up _and_ paid for the system, he considered it his, now. (The seller had not yet replied to my question about how to pay for the system- this is a bit different in Holland, as we usually just exchange bank account numbers here, and then just transfer the amount needed. Easy. So, I was waiting for him to reply with his account number. Rather, he did not reply, and when the pickup ocurred, he wanted cash. Even this is normally handled fine.. one pays the cash, and then gets reimbursed by whoever is supposed to actually receive the system.) Anyway... when I heard that, I tried to contact Bert, and eventually got a hold of him. And when asked about this, he indeed told me the above - as far as he was concerned, it was now HIS system. To make a much longer story short- I have taken legal action against him to get my system back, and the extra (legal and other) fees and costs reimbursed for. Sadly, Bert decided to not accept his being wrong, so this will be a full case of fraud in Dutch court. Your mileage etc etc, but I'd like everyone to take extreme caution when dealing with Bert, as his definition of "mine" and "yours", and the being right or wrong, might very well be different from what you consider such. This surely was the case for me.

computer junks for shipping cost (mostly PC related)

by vax9000＠gmail.com

Well, I received Chad Fernandez' box of pc leftovers. After taking out what I need and adding in what I don't, here is the stuff that is free to go. (ship from ohio) http://geocities.com/mscpscsi/PHOTOS/dscn3959.jpg --pentium 133, IBM 6x86MX PR300 --IBM PCDOS7, windows 3.1, Caldera DRDOS 7.02 --around 15 pieces of HP DVD+R bland disks (my DVDRW has trouble to write this brand, thus distroyed 10 of the 25 pack, but your drive might not) --a point and shot APS camera ($3 from yardsale) --CNet 10M/100M hub (the small fan inside became noisy, you might replace it. looks like the CPU fans of the 486 era) --all kinds of fans, 6 of them (some look like NOS) --a pile of floppy cables --11Mbps wireless lan PCMCIA card --AUI to RJ45 converter (you need this for your vax) --a xilinx student edition of fundation 1.3 --PC bay covers, slot covers, drive rails. --an EPSON MX-100 III printer (I bought it with $3 to print the tango/protel DOS version schmatics) Let me know if you are interested. I am willing to break the pile into two. One is the printer, the other is the rest. I am also willing to trash the rails, slot covers, bay covers, floppy cables, the xilinx, to drop the weight. The rest must go as a whole. Thank you. I will use UPS ground or fedex ground. If no one takes them, their destination is miserable. vax, 9000

John McCance / DEC Collection

by hugh＠openbsd.org

Dear vax enthusiasts, Some time ago John McCance donated a delqa card to me, and I responded with a thank you letter. Sadly, last week I received an email from John's sister, to inform me that John had died of a heart attack while helping his landlady deal with a basement flooded by the remains of Hurricane Charlie. She'd found my letter while going through his things. As John was an occasional participant on these lists I felt you should be informed of his passing, but there is a second reason for this posting. His family isn't sure how to handle the disposition of his collection of older computer hardware and documentation. >From the inventory they've compiled there appear to be several each of vt320 and vt420s, a large number of keyboards, a vax 4000 300, a vaxstation 4000, a strongbox of vms licenses, and many manuals, cdroms, etc. I also understand from my correspondence with John that there is a qbus scsi card of some sort, but this isn't a treasure hunt. The family would like to put any money the collection is worth towards his final expenses, or at least save hardware that John cared about from the dump. I am in Vancouver, but if one or more of you is near Cambridge, Ohio, and can commit to taking the bulk of the collection, you may contact me to work out specifics and put you in touch with the family. /Hugh

UTek (V) filesystems and boot blocks

by julesrichardsonuk＠yahoo.co.uk

Does anyone happen to know if UTek V's filesystem was compatible with anybody else's (hint: one that I might have a chance of reading with Linux, which probably limits me to sysv to be honest) Also does anyone happen to know the partition table / boot block layout? I'm not quite sure when UTek V sprang into being, but maybe it uses the same filesystem and boot block as earlier versions of UTek (which some of you are likely to have running on various Tek equipment) I'm going to try powering up my Tek XD88 tomorrow (it's currently warming up having been stored in the loft) and I'll take another disk image from the hard drive then - it'd be quite nice if I could mount the image from within Linux to have a proper look around the disk though (I recall Tek's shell being a little on the strange side) cheers Jules

Back on the list, with a request for help

by william.layer＠comcast.net

Hellos, I was on this list in the later 90's, but had since lost my link. Good to see you all, and hello to the new(er) folks. I'm trying to repair an Altair 8800 that came to me in 'kit form'. I'm missing the original 256 Byte memory board, and several chips have been robbed from the chassis, including the 8080 CPU. This repair will take a while, but I have two main concerns: 1) The control & display board has some missing chips and evidence of a burn-out in the far lower left corner. I'd like to know if there is a way to test the board for function prior to installation, as the installation includes some 70 or so wires. I'd rather not install this board only to learn that there was damage to the logic, that I failed to notice & repair. Also, can anyone supply me with an original Altair 256Byte memory board? 2) I need an 8080 CPU for this machine; can someone supply me with one? Would be cool to have the original style ceramic/gold chip, but anything that will actually work is good. Is it possible to drop an 8080A into the Altair CPU board and remain compatible to the original 8080? I have an 8080A in an unused box. I have good material to trade for these items, if available; let me know what you need / want. If you have any information, please send it to the list. Thanks, Bill

HP 21MX E-series front panel keyboards

by peterbrown10＠hotmail.com

Thanks Glen, Jay and Bob, I think that I now understand what's going on. The system that the keyboard comes from is an E series machine but all of the cards have been removed - it is quite possible that it at some time had additional booster microcode boards so that would expain the extra front panel cable. What sort of microcode board would require direct access to the keyboard? Bob - thanks for the kind offer of the 2113 chassis. I currently have a couple of full size 2113's in almost working condition (thanks for your continuing help on that one) my hope was that I could get a smaller system working as well - hence the need for the short keyboard. Glen - the document that you linked shows the problem quite well. What I need is the PCA 5060-8343 what I have is PCA 5061-1343. The metal work changes to convert a long front panel to a short one look to be fairly minimal and are probably within my capability (injury estimate: 2 bruised knuckles, a gash and some sort of deep graze) I note from the circuit diagrams that the keyboards are basically the same with the larger PCA having some addtional bi-directional buffering to drive the additional keyboard outputs. I thought that I might be able to saw down the keyboard PCA and discard the extra buffering bits but they seem fairly well integrated into the rest of the PCA. Does anyone have a spare 5060-8343 that they might be convinced to part with? or failing that a whole front panel assembly for a 2105? Thanks to all Peter Brown

More auction goodies

by tponsford＠theriver.com

Hi Folks, Well, today's auction haul includes: A Dec MV 3800 w/qbus scsi card (he-he) An Alpha 1000 And!! A functioning Tektronix 4051 Graphics system w/Data Communication Interface. (circa 1976) it also came with the RS232 Printer interface and the following documentation: 4051 Graphic Systems Operation Manual Plot 50 Introduction to Programming in Basic 4051 Graphic System Reference Reference Guide to 4051 Basic 4050 Series Basic Reference Guide amd 4051 Option 10 RS232 Printer Interface guide More information on this system can be found here: http://www.atariarchives.org/bcc2/showpage.php?page=282 What is really wierd is that I wrote some programs in Basic for this machine in 1977 using some of the built-in vector graphics routines, when I worked at the Defense Mapping Agency, now called the National GeoSpatial Intelligence Agency. I still have the tape cartridge (200K !!) when I loaded the tape... presto... instant retro memories. I even wrote some notes to myself!! ( Note to Homeland Security and to anyone else reading this email..It was NOT classified!!) Cheers Tom -- --- Please do not read this sig.

AMS EPROM programmer driver?

by cctech＠retro.co.za

Hi all I have an "AMS inc PROM PROGRAMMER COPYRIGHT 1983". It's an ISA card, with a whole bunch of TTL, 37 pin connector, ribbon cable to box with ZIF socket. I see that AMS is still around, and their web site mentions that they started out making EPROM programmers way back around 1983, but an email to them went unanswered. I need the software that originally went with this thing. Or if anybody has technical info (long shot). Can't be difficult to reverse-engineer, but it would take time that I'd prefer to spend elsewhere. Where I eventually want to go: I was thinking I could program this thing to apply vectors to a PAL to tell me what the equations in the PAL are (I'm intrigued by what's inside the macintosh PALs...)

Apple, Commodore, CP/M, Sun, misc. gear needs new home

by devin＠thecabal.org

I have a ton of classic and not-so-classic computers and accessories to find new homes for. Since I don't have the time or money to ship any of this, you need to be willing to pick up in the Seattle, WA area. Most of this stuff at least powered up the last time I was able to get to it, although there are likely some TLC issues on most or all of them that need to be attended to such as missing RAM or hard drives. One of the C-64s doesn't power up and a couple of the color NCD terminals don't have monitors or have monitors that are futzing, but all of the base units works. Some of this stuff I'm willing to let go for free, some of it I'd like to see at least $5 for. And there are a couple of items (the Auspex, the Sun Ultra 1 and disk pack, the Apple IIgs, the Cisco router) I would like to get a bit more than that from. Especially the Auspex and the Cisco router. Please e-mail me with what you're interested in, how much you'd be willing to pay, and what your schedule is like. I don't usually have any time during business hours to try to meet people places, unless it's at my home in Monroe on one of the days I'm working from home. Evenings and weekends are best bet if you're not willing to drive to Monroe. If I have to drive a load of equipment somewhere, I'm probably going to want to charge enough for it to make it worth my while. On with the list! CP/M x1 Northstar S-100 CP/M chassis, expansion cards, floppies Apple x1 Apple IIe system + accessories x1 Apple III system + accessories x1 Apple IIgs system + accessories x1 Mac 256 x1 PowerMac 7x00 system + accessories Commodore x1 Commodore printer x2 Commodore 64s + boxes of accessories x5 Commodore 1541 floppy drives Sun x3 Sun 3/60 pizzaboxes x2 Sun 3/80 pizzaboxes x2 Sun SPARCstation 2 pizzaboxes x1 Sun UltraSPARC 1 Creator 3D x1 Sun 6-disk external 68-pin SCSI disk pack, 6 18GB SCA drives Terminals x11 Wyse 30 dumb terminals x1 B&W 19" NCD X terminal x6 color NCD X terminals Routers, Network, Telco x1 Cisco 2516 router (48VDC telco power supply) x1 19" 1u serial/parallel print server x2 Fujitsu DSL modems x1 DirecTV DSL modem Specialty x1 Auspex NS 5500 (7' tall, 770 lbs!) This was a high-end server running a special form of SunOS 4.1 using Functional Multiprocessing (FMP). Auspex tells me it is the only one in private hands that hasn't been traded in or scrapped. True classic computing lovers only need apply. YOU MUST PICK UP THIS ITEM. I *cannot* transport it. Bring a big truck or van and suitable moving/tie-down equipment and padding. Misc. x1 ZIP SCSI external drive x1 HP parallel external CD burner Assorted A/V switchboxes Assorted TDMA cellphones + accessories -- Devin L.

Computer Products Inc analog data wide-range analog I/O -- free

by tomj＠wps.com

I will eventually post it to VCF website, but if anyone wants this it's FREE, you come get. I will NOT ship this item. It doesn't seem to have great value so it will eventually become landfill if no one claims it. It comes complete, in excellent condition, with manuals, schematics, programmers reference, cables, connectors, and even drivers for Data General NOVA machines (via thr 4300). It contains a 240 channel (two hundred forty!) analog input -- a big MUX. Some amplification. Nice power supply, nice card cage, lots of (probably Hg wetted) small-signal relays. Made in the mid 1980's. I find no google hits, and unfortunately the manufacturer name is too generic ("Computer Products Inc" yeah right). There's enough documentation to probably hook it up to anything. This is a rugged A/D subsystem that was wired to some smokestack in an oilfield, so it's not delicate (electrically). Not extraordinarily large or heavy, I'd estimate 50 lbs. http://wps.com/NOVA4/images/compprod1.jpg http://wps.com/NOVA4/images/compprod2.jpg

Data General NOVA4 status

by tomj＠wps.com

Well things are moving along very nicely, I'm going to power up in the next few days. I've been picking on it each night (30 min - 2 hrs) and it's pretty much ready to begin power-up. I took another look at the DG LP2 that "faulted". With a dry paintbrush and vacuum cleaned out the dustbunnies and a few spiders, esp. attention to the photo-interruptor. Loaded paper into it, powered up. This time carriage zeroing worked, everything behaved including self-test printing out the charset onto greenbar. The "new" ribbons seem dried out and the print is yellow-gray (likely from Bakersfield heat) but I'll try another or WD40 the ink ribbon. Washed it all down, other than a couple of scuffs it looks like new. Completed all the rack wiring, made a terminal (console) cable up >from the stub that got cut off for transport. Fan filter, rack panel fillers all in. Took a look at the other chassis; one now empty (DG salesmammals talked customer into too many (profitable) racks, as Bruce suspected :-) one's got the big analog mux thing (more, next message), the remaining has the second tape drive (6023) and the 4300 expansion chassis. Which I might keep -- ask me in a month -- it contains a 16 in/16 out digital interface and I think a one-channel A/D and D/A. Nice. Big though, we're talking 14" rack space but it's mostly air (lots of slots). Laid out all the docs, culled more dupes, which Bruce will get (hi Bruce :-) Bought binders on the way into work today for never-used docs. My lab, quickly outfit last fall (moved out of my nice, purpose-built lab, which we turned into a rent-generating apartment -- when I get sad, I think of the income :-) has crappy power. I'm not sure it's got enough amps to run the CPU, tape and disk. Umm, we'll see, the obvious way.

Motorola MVME188 Documents

by phirkel＠engsoc.org

Hello! We just located an old Motorola VME "minicomputer" with an MVME188 single board computer. Being a real vintage computing enthusiast, I decided to try to get the thing working, running OpenBSD. However, before I can do that, I need to reprogram the NVRAM in it. I figure if there were some documentation on how to do this, and how to actually use the machine someone here might have it! Any information on the board, the MVME332/333/376/328 would be much appreciated. Cheers. Phil

PC Adaptec SCSI BIOS format option?

by julesrichardsonuk＠yahoo.co.uk

Stupid question, but does anyone know if the SCSI BIOS format utility on Adaptec 29160 or 2940 cards does bad block checking and reassignment? I've got a 1GB Fujitsu SCSI drive here that has one dodgy block right in the middle of the disk (according to the Linux badblocks util, which still has a couple of passes to run). Unfortunately I want the disk for my Tektronix, and I think bad block mapping under Linux is only done at the filesystem level, rather than Linux being able to low-level format the drive and map blocks out that way. I'm a bit wary of the Adaptec BIOS utility - hopefully it won't trash the drive... cheers Jules

Data I/O progress... another question

by jwest＠classiccmp.org

My Data I/O 29B seems much more happy. All tin contacts cleaned with deoxit and all gold contacts cleaned with progold. Reseated all the chips (some were loose) and it appears to work fine for reading anyway. I'll check the power supply and calibration then try to program a chip. My current issue du jour is with Promlink. I can use version 3.4 just fine. I want to use version 6.10 though, MUCH easier on the eyes. However, any time I try 6.10 (with the high speed cpu patch), it chokes on "error sending Device Identification enable/disable command, is this a 29B unipak?" I thought my unipak was a model 2. It's not, it's just a straight unipak. I believe the device id feature is present on unipak 2 and 2b, and not present in just a unipak. From what I can tell, promlink v6.10 insists that the device identification feature be turned on. There is a setting to disable device ID checking in promlink, but either that setting doesn't work at all, or, it tries to send a disable device id command to the 29B, which won't understand it with a unipak, hence the error. Any known way around this? My 29B is firmware v 06 if that helps. Thanks! Jay West

update: UTek (V) filesystems and boot blocks

If you have a saved image you should be able to try and mount it using a 'loopback' file system on linux. No doubt that's what you tried. did you try any of the bsd parition programs, liked parted? who knows. All I remember is that sometimes we had to boot from a floppy and humm... that ran some sort of fsck? it's been a while. We never replaced a hard disk or tried to fool with one. I'd guess I'd be suprised if the file system was anything other than system 5 ufs. As I recall those systems were pretty vanilla unix wise. I don't think they had any bsd-isms in them (but I may be wrong). it might be interesting to hack up a copy of an old sys v fsck and open the image in read-only mode. that way you could fool around with various offsets and try to find the super block. once you know where the partition starts, and assuming you did a block copy under unix (so the blocks are in the right order), you might be able to grab an old copy of "sash" or something like that and get it to read the file system. at least then you could "ls". just some random notions. In the end, I think I'd write a program to transform the image into a new image which had a modern partition map pointing to the super block and then get linux to mount it. easy for me to say :-) -brad

The DFWCUG Historical CPU Preservation Society

by aek＠spies.com

Pat has lost interest in DEC collecting. I spoke to him when I was down there a few months ago. Here is an exerpt from a mail msg from him. Since however, one of us, The famous John R. Wisniewski, from DEC, has passed away, and due to the economics in the present time following 911, when everyone lost so much money and the purse strings have become very tight, we are not able to continue to seek grants or raise funds for a permanent place to store and show these, so at some time in the future, the entire collection will probably be liquidated. -- I will forward his current email adr through private email to Emanuel.

MOS 6507 Tech Spec's

> Anyone have any old technical white papers on the MOS 6507, I know its > just a slight variant of the 6502, but I would like to look over the > original technical specifications for the chip, pinouts, opcodes, > instruction set, etc... There are no specific documents on it. It's in the MCS650x data sheet. It's just a 6502 die in a smaller 28-pin DIP package with not all of the pins bonded out. Specifically, A12 through A15, RDY, /NMI, SYNC, SO, three NC pins, and one Vss pin are not available. The pinout is: /RES 1 28 Ph2 out Vss 2 27 Ph0 in Ph1 out 3 26 R/W /IRQ 4 25 D0 Vcc 5 24 D1 A0 6 23 D2 A1 7 22 D3 A2 8 21 D4 A3 9 20 D5 A4 10 19 D6 A5 11 18 D7 A6 12 17 A11 A7 13 16 A10 A8 14 15 A9 I'm looking for the Synertek 6516 data sheet, and Synertek technical notes 34 and 40. The 6516 was to be a 16-bit extension of the 6500 family, years before the 65802/65816. Synertek published a data sheet in mid 1978, but the part was never put into production.

How to sabotage a 5 1/5 floppy drive...

by wh.sudbrink＠verizon.net

without really trying: Part amusing story, part warning. I have my OSI C4P all buttoned up with the switcher supply tucked inside and I decide to fix another thing that has been bothering me for some time. OSI used MPI B51 floppy drives with most (all?) of their 5 1/4 inch systems. The B51 has an ejector spring that operates via a two step latch (mechanical latch, that is). The first step locks the spring when a diskette is inserted (so you can close the drive door), the second step releases the spring once the drive door is closed so that the diskette will be ejected when the door is opened. The latch alignment is finicky and this drive had the spring locked and stuck. So I open up the drive, straighten out the latch and then, since I have it apart anyway, decide to clean the head. I get a Q-Tip and some alcohol, lift the pressure pad arm and clean the head. (Anybody spot the problem yet?) I put everything back together and fire it up. Now the drive is flaky as heck. Read fails about 50% of the time. What did I break? I check to see if the track zero sensor moved. Nope, original paint spots are in place and uncracked. Did I, in fact, gunk up the head when I was cleaning it? I look with a strong light and magnifying glass. The head is smooth and clean. Did I pull some wire loose? Not that I can find. After fooling with it for a while, I notice that the click of the head load does not sound the same as before I took it apart. I look at the solenoid, everything seems OK. I troubleshoot this for several evenings. Finally, I go back to the head load investigation. I defeat the head unload rail with a wedge of paper (so that the head will be loaded whenever the drive door is closed). No help. Then, finally, I use a dental mirror to look at the head and pressure pad with a disk inserted. The pad is not in contact with the diskette surface! What the!?!?!? It turns out that the pressure pad arm is "hinged" not with a proper hinge but with a thin, somewhat springy, metal strip. There is also a proper coiled spring on top of the arm to provide more pressure but, when I lifted the pad arm, I flexed the "hinge" enough that the coil spring couldn't push the pad into contact with diskette surface. If you just look at it with the door open, everything looks fine. The pad arm seems to be firmly resting on the unload rail, ready to drop down onto the diskette when loaded. So, I disassembled the arm, gently flexed the "hinge" back to straight, reassembled and back in business. One of the oddest things I think I've ever had to work out. Maybe this is getting me ready to tackle my ASR33. Bill

RTL Logic

by dwight.elvey＠amd.com

Hi Most of these were designed such that a single output pullup resistor didn't use all of the sink of an output transistor. This means that two outputs tied together and would not draw too much current. DTL does the same thing and allows the wired AND. As I recall, with RTL, you only needed to apply power to one device if they were inverters since there was no other active logic, like flops. Dwight >From: "Steve Thatcher" <melamy(a)earthlink.net> > >I don't see how doing a wired-and is possible when RTL includes a pullup resistor on each output.

HP board no. 5061-6805?

by Arno_1983＠gmx.de

Hello everybody, once more I turn to the list in my quest for enlightenment... At the university's computer collection where I work, an HP board with the number in the subject turned up. It is a printed circuit board, about 7" wide x 5" deep with a 2x50 trace edge connector. The only visible parts are what looks like a few SMD capacitors; there are three black covers on the board, two of them like 1"x2" in plastic (neat the connector edge), the last one about 6"x3" and made from sheet metal (to the front edge). One of the smaller ones has a Static Discharge warning label stuck on it. There are two flat-but-heavy heat sinks bolted to the opposite side of the board, beneath the two smaller covers. One of the two black ejector handles on the front edge of the board says "512k RAM". I haven't found any useful information by googleing, only a few resellers. We would like to know what machine this part is for; I suppose this will make finding further information much easier. Thanks in advance, yours sincerely -- Arno Kletzander Stud.

Data I/O 29B help

by jwest＠classiccmp.org

I've got a Data I/O 29b with Unipak2 that is on the fritz. I thought it was working, but it's not. It frequently reads chips right, then 60 seconds later reads different values with different checksums. It's sporadic. It never gives any failure messages (other than bad verify ram to device). It just doesn't get the right values sometimes. I'm not up on the internals/repair of this unit, nor do I have time at the moment and I need a working one ASAP. Would anyone on the list know a shop that does repair of these units? Or maybe be able to ship me a 29B and/or Unipak 2 so I can at least determine which major component is ba and get over this hump? Thanks for any thoughts/advice :| Jay West
