The first impact printer that I owned was a Diablo 1340 (? the one with the very noisy separate PSU). Raw 12- bit interface. I hooked it to a 3-port S-100 parallel I/O board and then went about figuring out how to make it act like a regular printer under CP/M, including bidirectional logic seeking. I even wrote up proportional spacing tables and still have the code somewhere. Sometime in the late 70's, I picked up a copy of "Proportional Spacing with WordStar". It seems that WordStar 3.0+ did have hooks for PS, but they were a bit buggy. The document I purchased (still have it if anyone's interested) gives patches and workarounds for the bugs. I used it for quite awhile. FWIW, I have a Diablo 1620 (RO, serial interface) for adoption if anyone wants to see to packing and shipping. It works. Cheers, Chuck

old 386 pc, vga port - but one pin is blocked?

The VGA connector specification shows that Pin 9 is not connected and sometimes used as a key, that is, blocked, see: http://pinouts.ru/Video/VGA15_pinout.shtml I doubt it would hurt any future use of the cable to pull/break the pin on your monitor cable, but if you want to keep that side of things stock, you could use a 1/32" bit and drill out the position on the motherboard's connector, to allow the pin to pass through the plastic. - Jared

Keyboard for Beehive B-100?

by derschjo＠msu.edu

Hey all -- I suppose this is extremely unlikely, but does anyone have a spare keyboard for a Beehive B-100 terminal? Picked this up awhile back and it needs some repair (cap kit, etc...) but I assume that I'm probably never going to find a matching keyboard for this thing :). I'm not nearly ready to take this one on as a project, but I'm making a list of things that I'm keeping vs. things that need to get into other hands, and while I'd love to hold onto this, if I can't get a keyboard I'm never going to get any use out of it... Anyone have any leads? Thanks, Josh

The earlier versions used the $X controls, version 4 used the controls that were then used in the PLM86 compiler. Also, the DATA statement was eliminated and other language constructs were changed. PLM80 V3 code would not compile without mods. I remember it being released at about the same time the 8086 and PLM86 was was released and the effort was to make PLM80 and PLM86 somewhat similar. The PLM80 3.x docs are pretty much worthless if you are using the 4.0 compiler. 4.0 was also one executable, a big change from the PLM81 and PLM82 2-pass method the earlier versions used. >> Anyone out there have any information or pointers for me?

I had the -BF proms, when my 11/23+ had an RQDX3 and some RD52's. (This was back around 1990-ish) At that time, I was using?a Cipher F880?under?TSV05 emulation, so I wouldn't have noticed the lack of MU boot support. . .?? The TK50 was on my "new" 11/73. Darned if I can remember what I was running for disk back then. Fujitsu Eagle, with an SC03, maybe???? ;-) T

OT: Deciphering disk format

by sellam＠vintagetech.com

This is a somewhat OT request. I'm trying to recover files from a 4 disk (3.5") floppy set of Sybase SQL Anywhere for QNX Version 5.5.05. The first thing I tried to do is mount the disks under Linux using the QNX4 filesystem, but it bombs out. So I imaged the disks using ImageDisk (of course) and looked at the image file. It doesn't contain a filesystem as I had initially guessed, so now I'm trying to figure out what it represents. As best as I can currently determine it looks to be some sort of archive that spans across multiple disks. I'm not sure if this is a Sybase specific format, a QNX specific format, or what. The disks all have the following similar header information on T0, S0: vol 00001 00002 000000 5d69b244 11/Jul/99-17:00 wsql50 Disk 2 has: vol 00002 00002 000000 f9f96f2f 11/Jul/99-17:00 wsql50 ...etc. So the first group of digits is obviously the disk number, the third group is probably some CRC hash, etc. The contents of the disk are entirely binary. There is no text, lending further evidence that this is some sort of compressed archive. Does anyone recognize this as a header for a known archive format? Any help or insight would be greatly appreciated. -- Sellam Ismail Vintage Computer Festival ------------------------------------------------------------------------------ International Man of Intrigue and Danger http://www.vintage.org [ Old computing resources for business || Buy/Sell/Trade Vintage Computers ] [ and academia at www.VintageTech.com || at http://marketplace.vintage.org ]

PLM80 V4 docs needed

by jefferwin＠gmail.com

OK, time again to dust off the old brains out there. I found a ("the") ISIS-II emulator that runs under dos, which comes with a PLM80 compiler. It also comes with link, locate, objhex and other goodies. The PLM80 compiler identifies itself as PLM80 V4. I worked on the development of the ISIS-II stuff at Intel in the very early 80's as well as on the National Semiconductor Starplex system (anyone remember that one?) so I am able to tinker around and remember how most of this works, but version 4 of the PLM80 compiler is getting the better of me. I have the PLM80 Programmer's Manual, but it is for earlier versions of the two-pass version of PLM80, version 4 was a single pass version that used the linker and locator, all of which was the precursor to the PLM86 compiler and tools. I believe this version came out shortly before the 8086 was introduced, everyone went on to the segmented world and never looked back, which may explain why there isn't much out there for it. I am not able to locate any information on this version 4 of PLM80 anywhere, and the use and format is definitiely different from prior versions of PLM80. Anyone out there have any information or pointers for me? I have tried all of the excellent repositories of manuals and emailed Herb, his site indicates that he might have what I need. Anyone have an ISIS-II set of manuals sitting around that can check for me? Specifically, I am in need of: 98-00268B plm 80 programming manual, V4 Thanks.

More stuff to get rid of

by derschjo＠msu.edu

Well, once again I find myself with too much stuff and not enough places to put it. And my GF is moving in sometime soon so I really need the room :). So here's a few things I'm getting rid of, in case anyone's interested: Stuff is free, but local pick up (Seattle area) only! Works unless otherwise indicated. Anything not claimed 'll end up being recycled, most likely. Monitors: - Amdek Color-I. Color AND Sound! - Mitsubishi DiamondScan (CGA/EGA, composite, TTL) (needs a cap kit) - Magnavox Professional (EGA) - Gateway 15" SVGA (Trinitron) - NeXT 21" Color -- beat up, but worked last time I used it a few years back. - NeXT 17" Color -- same. Computers: - Dell Optiplex GX Pro - dual PPro upgraded to Dual PII (via overdrive CPUs). I have some RAM for it somewhere... works. - IBM PS/2 Model 25. Will not power up. Color screen, 20mb hard disk. Printers: - HP Laserjet 6P. Missing rear side covers (over power/parallel ports) but works fine. Relatively new toner cartridge. Misc Junk: - HP 1200B Oscilloscope. Needs repair. - Various AT and ATX cases, empty but I can throw in a power supply or two assuming I have one that fits. Inquire for details.

I too was very satisfied with the Sun IPX when it was new, particularly with Sun's Answerbook (far better than any other online manual system I used at that time) and programmer's workbench development system. I got to know and like the S-Bus when writing a device driver for an SDLC card. I still remember the phonecall requesting assistance with my device driver. It wouldn't work on the Sun 4m processor. It turns out the processor delays bus writes in order to share the bus with other processors, so I had to add a magic .asm spell to flush the writes.

Tektronix 4108 terminal?

by legalize＠xmission.com

Hi, I recently got a Tektronix 4170 and terminal from ebay. The terminal is a 4108, which I can't find in the 1985 catalog that introduces the 4170. The next catalog I have is 1989 and that lists no 41xx products. The enclosure for the terminal is very similar to a 4105, except that the finish is black and not that green-gray that is on most Tektronix gear of the period. The 4105 has a small cover on the back where you can add ROM to the terminal to enhance its functions. In this 4108, there is a cover in a similar area of the case, but it covers a set of 4 expansion slots. In my terminal, two of the slots are occupied. One looks to be memory and the other looks to be control. Had the tektronix terminal "mainframe" evolved by this time to be a substrate into which processing and memory cards were inserted to round out the system? I haven't opened the monitor case to look at it in detail. -- "The Direct3D Graphics Pipeline" -- DirectX 9 draft available for download <http://www.xmission.com/~legalize/book/download/index.html> Legalize Adulthood! <http://blogs.xmission.com/legalize/>

Unusual software carriers. (Was :Vinyl Data- Classic Computers )

by RodSmallwood＠mail.ediconsulting.co.uk

I remember taking the first Apple Lisa in the UK to be demonstrated on Tomorrows World. They had me in the studio as the program went out live. I sat on an unused display block about three feet off camera in case of problems. Presenters: Kiren Prendeville (photographic memory), Maggie Philbin (very nervous), Judith Hann( Nice lady - brought me a coffee!!)

Need help with dead 11/23+, FIXED :)

by charlesmorris800＠centurytel.net

I found the table to interpret the LEDs, buried around page 256 of the KDF11-BA manual. It told me that 0011 is: waiting for SLU Transmit. Odd, since there's no handshaking on the console lines :) That pointed me immediately to the console serial port, since I already knew the VT220 and cable were working via the loopback test. It didn't take long to discover (with my trusty Tek 545) that there was no clock on either UART in transmit or receive. The 5.0688 MHz oscillator was working (surprisingly - I figured the recent move had broken the crystal), and its signal appeared normal at jumper J21/20. But there was barely a wiggle on the two gates that it connected to. Poor continuity also, which improved when pushing sideways on wirewrap pin J21. Close visual inspection with bright light and magnifying glass didn't show much. I resoldered the pins and voila - RUN light on, startup message on terminal, booted from DL0: etc. So it was just a bad factory solder joint from the 1980's... Sorry I panicked :) -Charles

RPG has program flags triggered by that for subtotals, totals, page footers, etc. They were triggered virtually if the printer was not real-time. I don't recall the model number, but the IBM RJE terminal my high school had around 1976 didn't have a carriage control tape but was programmed with perhaps 4 "jobs" that defined the page size, carriage control stops, horizontal tabs, etc. It was a nice sit-down console with keyboard, chain printer and cabinet on the left with a 8" floppy drive. > Yes, if you skipped to a channel that WASN'T punched, > you fed lots of paper, which is why (if you were smart) > you punched the unused channels on the same line > as the "end of paper" channel (12). I punched them all for top of page. Sigh, I wish I had taken photos of my college's IBM 1130s and all the little things like the bottle of genuine IBM mucilage for gluing the carriage control tape into a loop. I still have a pad of IBM forms for planning printouts, with the carriage control tape along the edge to indicate where to punch the holes. > Oh, standard Fortran: > blank, single space; 1, top of form; 0, double space; > +, overprint (not supported everywhere). and - for triple space.

USENET via TV broadcast

by jeffj＠panix.com

> In the early 80s, I think there were some very low-speed data stream > systems via teletext ( http://en.wikipedia.org/wiki/Teletext ) > that could send the stream out RS-232. Is my memory correct? Perhaps. In the mid 80s, many technologies were attempted with similar (and often re-used) names 1) Reading the wiki entry, I was confusing Teletext with "Teletex" and perhaps something else http://en.wikipedia.org/wiki/Teletex I remember entering a contest, suggesting how a computer interface to the TV subtitles could allow linking things together (such as capturing phone numbers, URL, etc). My TV /still/ has no PC interface: USB or otherwise. (I think Sega's Dreamcast system received games via the cable TV channel). I remember attending trade shows in the late 80s where "smart phones" (desk sets with tiny terminals) and Teletex were touted as "the next big thing". Compared to Sears/IBM Prodigy, perhaps, but nothing compared to the Internet with hypertext browsing, multimedia and other new formats. In a way, today's cellular phones have replaced the landline "smart phones" since they allow texting and internet access. But here in the USA, teletext was just a terminal standard for low-res graphics, and it still used a modem via phone lines. The surplus terminals were often from France (obvious from the keyboard) since it was wildly popular there. 2) I'm unsure if it used the same technology as today's DSL, but AT&T used to offer employees "CO-LAN": piggybacking a dedicated serial line over the existing phone line. 3) Google finds nothing, but I remember project "Stargate" where USENET newsgroups were transmitted during the vertical blanking interval of the TV broadcast. I forgot if that was via satellite or cable.

Did anyone archive the old Everex FTP before it went down?

In one of the forums I belong to someone is looking for the EISA configuration files and drivers for a Everex Step VL/E type 18210 EISA motherboard (EISA config. utility !EVX1698.CFG). I figured that company was popular in the early 90's and somebody might have mirrored the FTP here (we are all packrats I would think). Thanks TZ P.S.

For those of you who aren't reading at home, these mnemonics mean: SPIM: Space immediate (1-3 lines) SKIP: Skip immediate (to carriage control channel) SKAP: Skip after printing (carriage control) SPAP: Space after printing (1-3 lines) All of these were control instructions that referenced the printer (unit #9).

The 1620 had two indicators for "summary line" (channel 9) and "end of printable page" (channel 12), which if you have a hard copy impact printer are probably still there. Yes, if you skipped to a channel that WASN'T punched, you fed lots of paper, which is why (if you were smart) you punched the unused channels on the same line as the "end of paper" channel (12). Oh, standard Fortran: blank, single space; 1, top of form; 0, double space; +, overprint (not supported everywhere).

The one I > remember had > 3 or 4 printouts taped together. Have any of the card decks survived? I don't have it in Fortran nor for IBM but I think I have a deck of cards for my ICT 1301 which produces a two or three page printout, printing across the perforations. At the moment, I don't have a 100% working card reader and I'm in the process of selling my spare 1301 so all my 'spare' time is used up trying to put back together a 5 ton jig- saw I dismantled over 30 years ago. At least I have an assembled one for reference but I keep finding differences between the two machines, one being the first one to leave the factory and the other probably being one of the last. I hope to make all my 1301 software, including the Mona Lisa, Snoopy, the lady on a stool etc available online sometime together with some of my many manuals and a simulator which will run on a Mac. Will need to find someone to host the archive in perpituity, maybe BitSavers would be willing to do it, but I haven't got the data off the Ampex ten track tapes yet.

Anyone know of a 1970s-style dot matrix "computer photo" generator/converter?

by ethan.dicks＠usap.gov

Hi, All, I'm sure many of us remember the "computer photo" craze of the late 1970s - go to a mall, get your photo taken by a computer, then buy one of a number of trinkets (calendars, coffee mugs, etc.) with your photo rendered by dot matrix... an old family friend even had one of those rigs - driven by an Ohio Scientific Challenger III (a machine I've long lusted after). There must be a way to simulate that look today - some sort of GIMP filter or web app or something. I've been googling around for "ASCII art" and "dot matrix photo", etc., and have found some interesting stuff (http://blog.modernmechanix.com/2006/07/27/ascii-art-1939/) but not what I'm looking for. Ultimately, I just want to take a snapshot of me and filter it to resemble that 1970s "computer photo" look. Any suggestions where to turn? Discussions of how it was done and how it could be done with vintage hardware now are interesting and probably on-topic, but not the goal of my question.

Your suffering from PCism, you expect it to work like a PC and it will not. I'm using a 45MB fujitsu 3.5" scsi drive That was given to me and a modified version of the ampro scsi bios. The base SCSI software supports a limited number of drives and SCSI to MFM bridges that were available in the mid to late 80s. Those would be the Xebec and Adaptec and one seagate drive all in the 10-30mb size range. Add to that at the time the AmproLB+ software was written SCSI nee SASI was still somewhat developmental. Yes, I had to take the Ampro sources and rework them a bit for that drive and debug them. The basic code is online in one of the repository sites and it's well done so modifying it should be resonable. I'll admit it's been 17 years since I did it and it's running so I haven't looked at it in a long while. Hope that helps.

Vinyl Data- Classic Computers / Indie music tricks crossover

by tpeters＠mixcom.com

http://www.kempa.com/wp/2004/03/09/vinyl-data/ Excerpt: One strategy that major record companies have been employing lately to deter downloading is adding bonus computer content to new CD releases. I recently discovered that this technique is not unique to CD?s, but had in fact been practiced in the vinyl era as well. That?s right: there were a handful of records released in the late 70?s and early 80?s that contained computer programs as part of the audio. This is totally insane, and totally great. Most of these programs were written for the Sinclair Spectrum home computer series. The Sinclair Spectrum was a relatively cheap home computer system that used a television set as a monitor and loaded programs from tapes. It thrived in England in the early 80?s: ----- 240.

HP9836C colour alignment (grey scale tracking)

by ard＠p850ug1.demon.co.uk

I am working on an HP9836C, in particular the colour monitor part. The original problem looked to be slight misconvergence, with red fringes. But I think it wasn't really convergence problems at all. I've been looking at the video amplifier PCB (the one at the back of the CRT) which not suprisingly contaisn 3 identical video amplifiers along with a blanking amplifier and components to pass the correct voltages to the CRT electrodes. Anyway, there's a resistor in each of the amplifiers that according to the colour bands should be 12.4k. In the green channel it's close -- 12.7k. In the blue channel it's nearer 17k, and in the red it's open-circuit. And I think this could be messing up the HF response of the red amplifer, hence the fringes. The problem is that if I replace it, I'll have to set what HP call 'colour alignment' and what I grew up calling 'grey scale tracking'. I've read the offical HP procedure (if you're interested it's pages 134-138 of the pdf service manual on http://www.hpmuseum.net/), and there are at least 2 problems The first is that I don't have a suitable photometer. The second is that even though it claims I need this photometer for the gain adjustment, the cutoff adjustments are done to 'barely extiguish the raster' I've worked on enough monitors to know that that's not precise at all, so I am wonderign just how accurte the photometer _really_ needs to be. Has anyone ever done this setup and can offer any tips? -tony

Wanted: HP264x terminal to host/modem cable

by legalize＠xmission.com

Hi, I've got several HP 264x terminals. These terminals expose a card edge connector off the back of the terminal to which you attach an RS-232 serial cable. Before I go to the trouble of making one of these, I wondered if anyone had one to spare?

Wanted: DEC VT1300 manual(s)

by legalize＠xmission.com

I checked vt100.net/manx and manuals are listed there but are not online and I couldn't find anything on bitsavers. Does anyone have information on this? I just know its an X terminal. Digging around on the net implies that this is a diskless VAX 3100 model 30. How does it get its X server loaded at boot up? -- "The Direct3D Graphics Pipeline" -- DirectX 9 draft available for download <http://www.xmission.com/~legalize/book/download/index.html> Legalize Adulthood! <http://blogs.xmission.com/legalize/>

ps/2 floppy drive

by rtellason＠verizon.net

I have this drive sitting here, and no particular use for it. I'd started talking about it to a list member some time back, but that never went anywhere. A label on one side says "DFL413C04A" and "Alps Electric Co. Ltd.", the drive has no faceplace on the front, and on the rear is a single keyed edge connector and no separate power connector. Anybody want to take this off my hands? I have no use for it. -- Member of the toughest, meanest, deadliest, most unrelenting -- and ablest -- form of life in this section of space, a critter that can be killed but can't be tamed. --Robert A.

Looking for some used floppy media

by ian_primus＠yahoo.com

I'm in need of some blank floppies... I need 8" soft sector disks for my TRS-80 Model II, I'm building an adapter cable to hook an 8" drive to a PC so I can write system disks for it. I've also got a Model 16 that's begging to get revived. I could also use some more 5 1/4" DSDD disks - I'm beginning to run low. A while back I had rescued a very large box of used disks from a school basement - and it turns out that they must have gotten damp at some point in their past life. Many of them have that "disk fungus", and won't format. I thought I was set for disks, and hadn't sought more out in years. I am primarily looking for used disks, I know that I used to run across large boxes of used 5 1/4" disks pretty regularly, but that was a few years ago. Thanks! -Ian

VAX 4000-300 shuts down

by IanK＠vulcan.com

All, I'm wondering if someone can confirm my diagnosis for a problem with my VAX 4000-300. One day, after it had been running for the better part of a week, I found it unresponsive with only the AC light glowing. I suspected an overheat problem, but the overtemp light wasn't on. Nonetheless, I shut the machine down, left it for a while and came back. It started up again, booted into VMS and seemed fine. I let it run for a half-hour or so, then shut it down normally. That was two days ago. I just tried to power it up again to do some work, and the power-on tests fail about halfway through (but never in the same spot, so I don't think it's actually a power-on test failure). The machine goes to the same state each time: just the AC lamp glowing. I even have the fans on high (and that's noisy), but no go. I figure it's time to replace the power supply unit (or refurbish it, but replacements are still relatively cheap). Any other thoughts? Thanks -- Ian

I took that loose, scrubbed pins lightly with very fine sandpaper and isopropanol, sprayed on silicone oil (but I'd recommend a contact cleaner instead), and re-seated both ends of the cable. Resistance across the cable (measured from solder joint on the back side of the analog board to solder joint on the back side of the digital board) went down from 10's of Ohms to fractions of an Ohm, and the system turned reliable. The resistance measurement is a pretty easy one to make, with the system off. I'd recommend that, at least. -- - Mark 210-379-4635 ----------------------------------------------------------------------- Large Asteroids headed toward planets inhabited by beings that don't have technology adequate to stop them: Think of it as Evolution in Fast-Forward.

Copying Computer Audio Tapes

by grant＠stockly.com

I'm trying to get some loose ends tied up, and that involves duplicating tape cassettes. I have a TC-WE635 "Stereo Cassette Deck". It says "DC Servo Controlled Motor" on the doors, so it must be good! : ) It has "Automatic Tape Selection", so I will have to trust that... It gives me a selection of: Dolby NR (OFF) (ON) (ON FILTER) and then a (B) and (C) Which settings do I want to use? It has stereo audio outputs on the back, of course, so I will also record the audio into a computer. However these days I don't want to put all of my trust into the computer... Grant

MAC SE instability and floppy issues

by jlobocki＠gmail.com

hello all, I have an original Mac SE here, which seems to be giving me lots of trouble. so far im in a new mobo, CRT (I let the magic gas out of the original one, second SE ive done that to!) SCSI and floppy cables, and floppy drive. the weirdest thing happens to it, and right now, im looking at power supply failure as the next logical guess. my problem is, I try to boot up my mac from either internal or external floppy, but regardless of which it is, it will read the disk, and on restart the floppy disk will be corrupted and will need to be reimaged. second, no matter the hard drive I put in it, the mac either will not see it, or it will go through, initialize, then at the end a dialog box will flash really fast on and off, and the computer I/O will lock up while doing this. the other thing that makes me think it is PS failure is the fact that one time i hooked the hard drive in to power while it was running, and when I did so, the fan speed bogged down significantly on spin-up of the drive. is there anyone with pinouts of this PS i can use to test it, or any advice as to what failure points I should check first? I tried google (they say its our friend...) and I get no info as to the voltages of the logic board connector or the like. any help is most appreciated!! thanks

The dumpster is here (re: Stuff available for free/donation -> cheap)

by rescue＠hawkmountain.net

The dumpster is here... and I'm prepping for the first pass which I'll be doing this weekend. In addition to stuff I've previously listed, I also have a ton of Sun 411 drive boxes. Most people probably don't want any, but if someone wants a spare power supply, the fan, or the internal scsi cable, a replacement plastic top, etc... let me know... That pile of 411 cases has dumpster written all over it. I still have a bunch of SS10 bare bases. If you want a spare mainboard, power supply, internal scsi cabling, etc... speak up now.... I have one bare SS20 base left (with JPL Y2K 'OK' sticker on the front :-) ). I have a QMS PS810 printer that is going to the dumpster. It is a parts printer. The fuser I think is gone, and the power supply is suspect. The logic board is known good. This printer served to 'rescue' a QMS PS815 (donating it's power supply, fuser, and the plastic 'shell'). Any parts wanted off this (mainboard, etc) let me know. -- Curt

DEC 40th anniversary CD

> Out of curiousity wouldn't 'dd' on UNIX, or a the following on VMS work? A hybrid disk has multiple sessions recorded on it. On the DEC disk, the first session is a music track, and the second is a 9660 file system with Windows gunk on it. The tarball has everything from the second session. I tried making an ISO image, and it only saves the first session. The content is fairly lame. Some blocky AVI's, and the DEC timeline with low resolution images from the DEC archives, pretty much identical to the timeline that was on the DEC website. The whole thing is about 90mb.

Closed vs. open source timeline.

by andy＠smokebelch.org

So whilst the GNU project was announced in 1983 I've heard many examples being cited of the source to software being shared prior to this, E.g. IBM's VM up to vN.N. And indeed recall reading somewhere that up until a certain point in time the source to most if not all software was available. As vendors made their money from hardware sales and you were unlikely to be able to buy a clone or build a machine yourself, and so safe-guarding source code was not a major concern. Does anyone know if the history of closed/unavailable vs. open/available source is documented anywhere? Ideally in a book or journal that can be properly referenced.

Otrona Attache: The adventure continues

by derschjo＠msu.edu

Thanks to TonyM, I have a replacement power supply that works and I now have the Otrona mostly running. (I do intend to repair the original power supply -- I found what looks to be a bad transistor and I've ordered a replacement (can't find it at the local shop.)). The Otrona almost works properly, it just won't boot from floppy. I need a bit of help debugging the floppy controller. Thus far I've verified that the following are good: - The drives themselves and the disks I'm trying to boot from (hooked the drives up to my PC and used ImageDisk to dump the disk contents successfully) - The drive cable - The NEC 765 controller (was originally bad! replaced with a known-good 765 from an old PC floppy controller and this improved things somewhat.) Symptoms are: Drive spins up, seeks to track 0 but won't boot; running the ROM diagnostics (thanks to Bob for a scan of the service manual!) helps narrow down things a bit: - The "Format" diagnostic runs, which means the heads load, the drive seeks, and enough is working so that the Otrona thinks it's formatting. I've tried reading the resultant diskette using ImageDisk and it chokes on it, so I'm not sure it's formatting correctly. - Reading or Writing a sector on a known good, CP/M formatted floppy fails. The error code returned (4004) indicates a missing Sector ID. There aren't a lot of chips involved in the floppy controller (about 12 or 13) so I'm hoping this shouldn't be too hard to track down. Any suggestions on where to start? (Schematic at http://oldcomputers.net/Attache_Schematics.pdf on page 6). Would it make sense to start investigating the chips leading back from the /RD DATA pin?

HP NetServer LE config problem

by Arno_1983＠gmx.de

(This is a resend - I never got my original message back so I suppose it got stuck in that list server hiccup a few months ago...) Hello everybody, we recently acquired a HP NetServer 4/33 LE (later upgraded to 100 MHz) for the University computer museum and are trying to get it going now. This involves some configuration changes for which one needs a configurator disk - the one we got with it is flaky (reads unreliably). We did download the Netserver LE ECU (EISA configuration utility) disk images from HP's website but when the changes are made, the program complains that the actual system board ID differs from the one in the configuration file and does not save the new configuration to the CMOS. Clearing the CMOS via DIP switch did not improve the situation. We finally got the original disk to boot once but got the same message. A BIOS update/reflash is not possible because the update utility wants Video BIOS shadowing enabled, which would - you guessed it - be done by means of the configuration utility. Am I doing something wrong here, do I have the wrong disk image or is our mainboard toast? As usual, thanks in advance...

Buying Vintage Technology

by ubergeek316＠gmail.com

Hi, I have a blog called "Vintage Technology Collector" (http://vintagetech.org) and working on an article called "buying/selling vintage technology". I have bought several vintage personal computers and device over the years, and one of the best and most reliable sources of this equipment is eBay. I am wanting to find out if anyone has any better places for buying/selling vintage electronics. Thanks, Jason

Got Nova 1220, but no key :(

by stephane.tsacas＠gmail.com

Hi, I have this Data General Nova 1220 sitting here which seems in good shape. But I don't have the front panel key, which is in the "lock" position. The PDP11 keys I have do not work :( Any hint ? Thank you ! -- Stephane Paris, France.

time to part with my PDP-11 system

by gerhard.kreuzer＠liftoff.at

Hi Dan, I am interested, but you need to think about shipping it, on my cost no question. On the other hand, I will try to organise a VAX-Station, I think, I can get a 4000 or something like this, maybe more. With best regards Gerhard PS: Do you have pictures?

Still FS: S-100 boards

by charlesmorris800＠centurytel.net

I still have the following S-100 boards for sale if anyone's interested: Wameco QMB-9 "The Little Mother" 9-slot motherboard with five connectors. http://tinypic.com/view.php?pic=20qzvq0&s=4 8K static RAM (2102) board by Ithaca Audio, fully socketed and populated. Needs a couple of heat sinks for the 7805 regulators. http://tinypic.com/view.php?pic=29lefr8&s=4 Piiceon 8K Program Saver board (2708 EPROM programmer). Complete except for the TL497CN switching regulator chip. Includes two 2708's, can hold eight. http://tinypic.com/view.php?pic=2r7x7jt&s=4 NOTE: The above boards were never powered up or tested (lost interest in the early '80's). No guarantee they will actually work! VB-1B Video Interface card by Solid State Music. This one was actually working with a different (homebrewed) 8080A board way back in 1979. I think it's 64 characters x 16 lines, monochrome of course. http://tinypic.com/view.php?pic=2qa6bde&s=4 Please make offer on one or all. Shipping will be from zip 65775 (US). thanks Charles
