I would like to acknowledge the passing of Prof. Pat Hume. He was a pioneering programmer in Canada working on TRANSCODE(before most programming languages came along) and published/co-authored several early books on programming for high school and university students. He was also a popular host of the CBCs "The Nature of Things" a pioneering TV science program. Happy programming/computing. Murray--

looking for TML Pascal for MPW IIGS

by retrogear510＠gmail.com

I am using Mac OS 9 to run the MPW IIGS environment to assemble some old source code. I have problems when it comes to Pascal code. I see in other source that it specifically requires TML Pascal. The version I think I need is TML Pascal for MPW IIGS 1.0. This is not TML for the Mac or Apple IIGS. Googling reveals others have searched for it which resulted in dead-ends. This software may be extinct but I thought I'd ask if anyone has a copy? Larry

This whole thing started when Tony asked why you REd whatever machine it was, when he had already done so, and there is a lot of other equipment that needs reverse engineering. That set you off on a rant about mistakes Tony had made, how many machines you had REd etc etc. If you had just counted to 10 before replying, and instead asked Tony what he meant, the whole thing could have been kept to a civil level. Instead it all degenerated into some kind of pissing contest. You did actually come across as feeling threatened, not as being reasonable. You made yourself the aggrieved party by your knee-jerk reaction. Unless Tony writes one thing and means something completely different, if you read his responses, it does rather look as if you have misunderstood him and gone off the deep end. I'm sorry, but you started this fight yourself. /Jonas

Pdp11 Ethernet cards

by roe＠liveblockauctions.com

I'm looking to equip my unibus pdp11/34a and qbus 11/83 with Ethernet cards. I have no experience with old DEC network hardware, and I need advice. On the qbus side, what is the difference between a DELNA and DEQNA? Is one superior? Is there a better alternative? As for unibus, any advice at all would be great. If it matters, my 11/34a has both cache and floating point, 128kw memory, but I don't know if there are any operating systems with tcp/ip that will run on it. Thanks for any thoughts.

16kb variant of the IBM 5150 - Bell & Howell

by swtpc6800＠comcast.net

The original Apple II case could be easily open by students and was not suitable for school use. (It may not have had the proper UL approval.) The dark Bell & Howell Apple II case was locked down and somewhat student proof. Bell & Howell also knew how to sell projectors and other audio visual equipment to schools everywhere. This is how Apple fortuitously stumbled into the education market.

I think it is important to allow other people the benefit of the doubt. If someone says something that one at first takes personally, one can always ask politely what they meant, as it is quite likely that one has misunderstood what the other person meant. Tony in particular, apart from his British humour, I believe is very uncompromising about doing what he thinks is right, for which I think he deserves respect, and even if one disagrees with his idea of what is right, one has to accept that that is the way he is, just as we expect to be accepted the way we are. /Jonas

DEC F-11 Pinout

by kylevowen＠gmail.com

I'm planning on constructing a PDP-11 S-100 card and intend to use the F-11 chipset. However, I've yet to find any decent information on the F-11, or the J-11 for that matter. Does anyone have the pinout information, or any other good design info? Having the MMU pinout might be helpful as well. I know there has been interest in this before and would love to help create a final product. A PDP-8 S-100 board using a 6100/6102 or 6120 would also be nice. What to do with the extra nibble in RAM, though? Checksum? Thanks, Kyle Owen W4GNU

Emulex SMD/SDI converter subsystem (SMDI)

by p.gebhardt＠ymail.com

Hello list, the recent post of Lyle regarding Emulex tape couplers reminded me that I've been having an Emulex converter subsystem named "SMDI" for years now, but was never able to use it. The reason: This subsystem is housed in an extra 19" enclosure and unfortunately, I obtained this box without any SMDI converter boards. The idea of that box is neat: SMD-discs can be attached to DEC SDI-interfacessuch as KDB50 or HSC50/70. I'm not aware of anybody having such a box. Is there anybody out there with such a thing, possibly in usage? What's your experience with it? Anybody who would be willing to trad/offer one of those boards which fit into the SMDI-box? In that case, please contact me off-list. Kind regards, Pierre ? ------------------------------------------------------------------------------- Pierre's collection of classic computers : http://classic-computing.dyndns.org/

HP 9830A always turns on with blank display

by dfnr2＠yahoo.com

Hi all, I have a 9830A that I haven't powered up in a while.? Previously, it would take a few seconds to get to the lazy-T prompt, but now on powerup, the screen remains blank.? I got Tony Duell's phenomenal schematics, and was all set to start debugging, starting at the clock, but I checked the user manual first, and following the suggestion in the setup section, I hit "STOP", which brought me to the prompt, and from there, it appears to be functioning normally.?? However, the machine powers up this way every time--never to a prompt.?? Does anyone have an idea why the machine is behaving this way?? I'd love to have it power up to a prompt. Also, does anybody happen to have schematics for the infotek bitslice processor?? I don't have one, but I'd be very interested in trying to acquire or recreate one. Thanks, Dave

Emulex tape controllers...

by lbickley＠bickleywest.com

I was recently helping a friend clear out one of his storage lockers and found (3) Emulex TC12 controllers. They look to be NOS and are in shipping boxes. The manual is on bitsavers: http://bitsavers.trailing-edge.com/pdf/emulex/TC1251002-E_TC12tech_Jun83.pdf The board emulates a DEC TS11 Unibus controller. It functions in both streaming and formatted mode, supports 800 and 1600 densities, and has the industry standard Pertec interface for PDP-11 and VAX-11 computers. It is compatible with all DEC software which supports DEC's TS11 controller. If you are interested in one or more of these controllers, make a reasonable offer - and I'll give you the owners PayPal address to send the funds (or check if you're so inclined).

Victor 9000 in southern California

by tosteve＠yahoo.com

Hello, I bought this complete Victor 9000 system from a local guy, mostly because he needed the money. It powers-up and displays, but won't boot any of the floppy disks for reasons unknown. I paid $100, so if anyone wants it, I will let it go for the same amount. It includes the keyboard and monitor, all in the giant original box.It weighs 60 pounds, so local pick-up is preferred. Thanks- Steve.

Actually, it wasn't that bad. The feel was horrible, but it was quite reliable. I used mine as a freelance translator to translate several fairly large books, as well as keeping my accounts on it and letting the kids play games on it. I never had any problems with the keyboard. /Jonas

I kind of like the IR keyboard and it seems to work better than what the press let on, but it does seem to eat batteries (at least the chicklet one, not sure about the enhanced keyboard). I wouldn't want to type a paper with it for sure. Still, I imagine this is probably a matter of asking the right questions for a market survey. What, if any, detail was the focus group privy to when the compromises to the keyboard were asked about? Did they follow up afterwards? Seems like they probably didn't and just ran with it. The PCjr is kind of a neat machine in its own right, but I have to think that it is caught between a rock and a hard place. On one hand, IBM wanted to capture a chunk of the emerging home computer market, but on the other hand not cannibalize sales from the more expensive (and more expandable) IBM PC. It obviously had a couple of things going for it over the PC (graphics and sound capability), but it was also more or less priced basically smack-dab between the Commodore and Atari 8-bit offerings and the IBM PC itself. In a practical sense the memory limitation made it about as powerful as a C-64 or Atari 8-bit machine when accounting for tradeoffs in custom chip capabilities vs a less powerful CPU in the case of the other 8-bit rivals. Most of the design compromises for it vs the PC seem rational, with the exception of using BERG connectors for everything, which is nonsensical to me. Well, that and the fact that IBM didn't offer upgrades for a full 640kB RAM. I'm sure that the latter would have made it a bit more palatable to people since the vast majority of PCs weren't sold with 64kB ( or 128kB for that matter). From what I can tell, the DMA restriction isn't too much of a problem in practical use, with the exception of the serial port), so with just the additional memory it probably would have enjoyed fairly good software compatibility with its big brother.

Bad Keyboards

by john＠yoyodyne-propulsion.net

The worst keyboard I ever typed on was attached to something called (I think) an "Infoton" terminal. Yeah, this: http://terminals.classiccmp.org/wiki/index.php/File:Infoton_Vistar_GT.jpg http://bitsavers.trailing-edge.com/pdf/infoton/Vistar_Technical_Users_Manua… It was upper case only (which is horrible enough)... but the keyboard. It was like typing on a wet sponge. I wish I could find one so I could (gasp) take a sledgehammer to it. The ASU remote sites had a large number of these, and a small number of VT100s, and everyone was desperately trying to avoid them.

OK, Tony seems to push the buttons of a few people on here who don't get his particular brand of humour/irony and are also not willing to consider his circumstances and cut him any slack, but IMO this particular personal attack is almost completely unjustified.

PDP 11 BASIC from Papertape

by billdeg＠degnanco.com

In the past I have participated in threads here about the DEC-modified version of the ASR 33 Teletype, and the role of the Reader Run relay card (part number 4915) for loading papertapes. I wanted to report that I have been able to load BASIC from papertape using a stock ASR 33 on a PDP 11/05 without the presence of the reader run card installed. I did have to hit START on the teletype to load the tape at the right time, but otherwise it works just fine. I assume that the load does not require a lot of starts and stops and therefore no need for the reader run. You don't know unless you try, so now I know. I was also happy to find that BASIC remains in core memory, ready to run from 000000 on my 8K system the next day, without having to re-load the papertapes (abs loader and BASIC). I have not yet saved and re-loaded a BASIC program but I hope that'll work without the reader run. I would assume however that I'd need the reader run for more complex operations like assembling programs. I have another UCC-6 with the beginnings of a homebrew reader run that I need to complete. If anyone has an actual 4915 for sale, I'd be interested. Bill

FS: Apollo DN300

by kurt.m.nowak＠gmail.com

I have an Apollo DN300 that's been sitting in the corner of my garage which I would love to find a good home for. It powers up, and seems to pass self test but does not respond to any keyboard strokes. I will entertain any offers but if no one wants to buy it, I would be happy to see it go to a good home for free (you pay shipping of course). These were stand alone work stations and so it does not have a HD so you will need another node to boot from. I might have a disk enclosure lying around but you will have to procure your own ESDI disk. Unfortunately this machine will NOT run on anything newer than SR 9.7.5. It will come with a keyboard, but it is missing the space bar. I know, im making this offer sound SO attractive! Here is a link to some pictures https://plus.google.com/photos/112158735340501596756/albums/590547810466293… Please respond to me off the list, if you're interested in more information. Thanks, Kurt

Reverse engineering flamefest, was: HP 9830A always turns on with blank display

by jonas＠otter.se

How about y'all stopping flogging this by now very dead horse? If you don't want to fight via private email, then please don't do it in public either. You are only showing the rest of the world how rude you can be and how clever you think you are. I am not addressing this to anyone in particular, because I do not want to get involved, only to get you to stop making d**ks of yourselves in public. By all means say what is wrong or right in someone's schematic, but please keep the personal attacks out of it. /Jonas

Aug. 3-4-- HUGE lot of vintage micros f/s @ MARCH event in central NJ

by evan＠snarc.net

Hi all. Remember this thread: http://www.vintage-computer.com/vcforum/showthread.php?37642-NJ-USA-Large-l… .....? Now it's time for we in MARCH to sell everything on the owner's behalf. Rules are what you'd expect: nothing's being tested; nothing's being shipped; cash only; no parting out; no "dibs"; etc. .... you've got to BE THERE or be square. The following list is around 90% accurate. I might have mis-counted, for example, where there are more than one of the same machine. Also, the owner said there's a few other random items that will be available. And last but not least, we in MARCH might grab one or two specific things for the club collection; for example we might want one or two of the Franklins. Keep in mind, the Aug. 3-4 event is NOT the VCF East -- that's not until next April -- this event is primarily a vintage computer repair weekend. Entry is $10. Without further ado, here's the rough list: Amstrad PPC640 Apple II+ (x2) Apple IIc (several...) Apple IIe (x4) Apple IIgs (x4) Apple Lisa II (possibly XL; not sure) Mac Classic Mac SE Mac 512 Mac Plus 1MB Mac IIcx Mac IIci (x4) Mac II Mac II Plus Mac Powerbook 170 Mac LC Mac LC3 Mac Quadra 605 Mac Quadra 950 Mac Quadra 800 Mac Quadra 700 Mac Quadra 800 Mac Quadra 700 Mac Portable Disk II (x4) misc.

LCD rot?

by pye＠mactec.com.au

I have just pulled a heap of old Apple PowerBooks and Newtons out of storage, and have discovered that quite a few of the LCDs that were perfect last time I looked at them (some probably not for seven years ago now) have deteriorated to the point that they are no longer usable. Problems vary from big black splotches on mono screens, to colour screens with almost the entire display from the centre out showing only the backlight. What are the causes for these kind of problems? Heat? Humidity? They have been stored for the last six or seven years in a cool dry environment, but did spend one summer in a storage facility that could have reached 40 deg c at times. Chris

Any of you old timers (or otherwise) know what these components were and what they might have been used for? A keepsake from my wife's grandfather's career with IBM. I'm guessing 1960s vintage, give or take. http://imgur.com/PYJCrU0 Thanks, Win

There's an iMac (CRT-based) turned up for sale locally with a white / clear pale-blue case; is it safe to assume that it's either: A first-generation (or first-gen rev C/D), An iMac SL, An iMac DV/SE ... i.e. Apple didn't offer that case style/color on any of the later systems, so it's got to be one of the earlier ones from around 1999/2000? cheers J.

HP 98xx

by cc＠informatik.uni-stuttgart.de

I have scanned now one binder containing blueprints/schematics for the HP 9810 and 9820. There may be more hidden somewhere in the archives. I'll scan that, too, when I find them. I hope that I also have schematics for the 9830. For now, they are mostly single page TIFF images; multi-page parts are packed into PDFs. As usual, they can be found on our FTP site: ftp://computermuseum.informatik.uni-stuttgart.de/hp/98xx/ Enjoy ;-) Christian

Writing article on computer museums for www.destinationz.org/

by gabe＠gabegold.com

I'm writing an article on computer museums for www.destinationz.org/ They're everywhere -- once I started looking for them. I knew about -- have toured -- Computer History Museum -- www.computerhistory.org/ And I recently saw a great presentation on The Living Computer Museum -- www.livingcomputermuseum.org/ But I hadn't known about American Computer & Robotics Museum -- www.compustory.com/ I wonder what other museums exist -- especially any with relevance to mainframes -- so I'll appreciate tips/pointers and, especially, hearing about experiences joining/supporting/visiting them. (Or contributing artifacts to them. Maintaining private collections of mainframe components as some people I know do is interesting but might not qualify as operating a museum. My wife called one such residence decorated with large mainframe components a "computer mausoleum" -- but I liked it.) Too bad, I have no budget for world tour of museums -- so I'll have to visit virtually. ==> Please copy me directly so responses don't get lost in list digests. Thanks... -- Gabriel Goldberg, Computers and Publishing, Inc. gabe at gabegold.com 3401 Silver Maple Place, Falls Church, VA 22042 (703) 204-0433 LinkedIn: http://www.linkedin.com/in/gabegold Twitter: GabeG0

Best TOPS-10 tape imaging and DECsystem 10/20 emulation....

by rescue＠hawkmountain.net

Been away from the list for a while, but a recent discovery has rekindled one of my classic computing projects I always wanted to do... I have 3 tapes that I have re-discovered that came from my earliest college days. They have stuff from my days on a TOPS-10 system. I have a DEC SCSI based tabletop tape drive to read these with. What is the best way to image these, preserving their contents ? Also, what software will put these in a format I can use with an emulator ? Does anyone know if any of the emulators can mount the tapes directly >from the emulator through the SCSI bus ? Or is the only way to image these in a format compatible with the emulators ? Anyone know what the best emulator is for DECsystem10 ? How about DECsystem 20 ? Thank in advance, -- Curt

HP 7906 wish list

by mloewen＠cpumagic.scol.pa.us

The recent talk about 7906 drives prompted me to post this. My wish list includes a 7906H (preferably), or a 7906M (with 13037) would be acceptable. Does anyone have one taking up space? East coast (US) would be preferable. Mike Loewen mloewen at cpumagic.scol.pa.us Old Technology http://sturgeon.css.psu.edu/~mloewen/Oldtech/

Microvax II won't boot, hardware error?

Even though early versions of VMS do not enforce licensing through the LMF, it's still required. Media can be borrowed. HP doesn't care where you get it, but asks that it not be posted for public download.

Not-100%-classic: OpenGL driver dev for Mac OS 9?

by fraveydank＠gmail.com

I'm going to call this "classic by fiat", since Apple has decided that it's "vintage" enough to have stripped most of the content >from its website by now, though it's not clear that any of this was ever easily available there to begin with. I'm looking for any guides, sample code, etc. on developing OpenGL drivers for Mac OS 9, since an evening with Google has proven mostly fruitless. I've found plenty on developing OS 9 OpenGL *applications*, but I'm looking for even just a reference for the hooks that need to go into the driver. So far, I've come up pretty empty. I always have the option of reverse-engineering existing drivers, since I have a copy of IDA Pro, but that's obviously a BIG time commitment. Anyone have such a thing in their possession or know to whom I should speak? I'll be posting this on a few lists/forums. - Dave
