Hi folks, I just read your responses to my TU56 lamp question. That brought the "lamp discussion" back to onto my mind. I have some information to share, perhaps it might help: I recently got a box of original lamps from a retired DEC service engineer. The blue ones (blue seemed to be VERY important as someone also wrote the word "blue" onto the box!). The box is labelled "Oshino Sub-miniature Lamp". Made by Oshino Electric Lamps Works, Ltd, Shinagawa, Tokyo, Japan. The box calls the lamps "OL-2, 10V, 40mA". The part number is 12-09129. The "OL-2" is stamped onto the box along with the ratings. The part number is written by hand - together with the "blue". The lamps carry the part number. (I have another box with lamps for RK05 etc. They have the part number on the box and "OL-1" directly on the lamps.) Now I used google - and Oshino is still around! I found their German website with some part lists. All article numbers start with "OL-". The T1 3/4 sized bi-pin lamp that takes 40mA at 10V is now called "OL-367BP". Perhaps it's just the same. The light output is told to be 0.08 MSCd. The company's logo is the same as on my box and the CEO's name is Takeshi Oshino. So there is a good chance to get the original lamps. I have not yet checked if the lamps I got were the same I find in my machines, but the brightness perfectly matches and they come from DEC. Stored together with little boxes containing new DEC labelled ICs and transistors. That should vouch for them. Best wishes, Philipp :-)

Trouble installing system on a Macintosh Quadra 660AV

by thrashbarg＠kaput.homeunix.org

Hi, I've got a Mac Quadra 660AV which refuses to install any system software, except System 7.1, which it refuses to boot from (apparently it needs a newer version, but web pages about the Mac say it should work). I've tried System 7.1, 7.5 through 7.5.3, and Mac OS 7.6. It happens right at the end of the install, when the system is being finalised. I've replaced the battery, cleared the NVRAM, updated the disk driver and set the date. I'm using the original hard drive. Does anyone have any ideas? Alexis.

Request for computer displays at 2010 Midwest Gaming Classic

by wgungfu＠gmail.com

Heya all, doing the annual display request for the museum hall of the Midwest Gaming Classic. Looking for people from the list who specialize in classic computers to run a display area for their computer of choice at the show. I cover the bulk of of the pre-'84 consoles and computers, so it's harder for me to set up as dedicated a display as somone who specializes. The MGC is an all encompasing electronic entertainment show (consoles, computers and coin-ops from past to present). We hit around 4000 people this past year's show, and are expecting even more growth with the move closer in to Milwaukee this year (we're at about 30,000 sq. ft now as well). Besides the retro crowd, most of our actual attendance are the casual and family gamers of all ages, so it's a chance to expose this great hobby to a newer generation. Currently we have people coming to support their own Commodore and TI areas. Here's photos from the show this past March to give everyone a feel for the show: Museum area http://www.flickr.com/photos/91071283 at N00/sets/72157615834963880/ Underdog Chamber (also in the museum hall) http://www.flickr.com/photos/91071283 at N00/sets/72157615746538685/ Family Game Room (also in the museum hall) http://www.flickr.com/photos/91071283 at N00/sets/72157615835258766/ Competition Area http://www.flickr.com/photos/91071283 at N00/sets/72157615745281965/ Coin-ops http://www.flickr.com/photos/91071283 at N00/sets/72157615745260231/ Vendling hall http://www.flickr.com/photos/91071283 at N00/sets/72157615745200729/ It's Saturday, March 27, 2010 from 10:00am to 8:00pm and Sunday, March 28, 2010 from 10:00am to 5:00pm, at the at the Brookfield Sheraton, just outside Milwaukee, Wisconsin. Please contact me if you're interested in helping out, or midwestgamingclassic.com if you're interested in the show in general. Thanks! Marty

Picked up some new toys today...

by brianlanning＠gmail.com

I actually got some good deals from ebay today. One was an amiga 1200. It included a 68030-50 accelerator board (with scsi controller), 3 external scsi-2 hard drives, an external nec scsi cdrom drive, a 3com pcmcia network adapter, a commodore 1902 monitor, and about 300 floppy disks. (I will never run out of floppy disks again, lol) That was $250. I also bought a power computing ppc604e mac clone with a 17" (i think) apple monitor, several keyboards, and a mouse. That one was $20. :-) He also mentioned another computer that he'll be pulling out shortly. He claims it's an ibm 5150 or 5160 with original cga monitor and... a 386 upgrade board. Not sure what's up with that, or even if he'll want a reasonable price for it. I guess we'll see what happens with that. brian

Anyone near Grove City, PA?

Hi, Anyone near Grove City, PA ??? I have a solder rework station out there that needs to be picked up, its about 100lbs or so and I don't want to chance it being shipped. I'm willing to meet off of Route 84 to anyone willing to pick it up and make the trip part (or most) of the way to Carmel, NY (its about a 5+ drive each way and I'm not allowed to drive more then 2 hrs right now because of the heart surgeries I had.) I'm willing to pay anyone for the pickup and delivery, let me know off-list, thank you. Curt

Sinclair ZX80 on Ebay

by julianskidmore＠yahoo.com

Hi folks, > Well I was. Was the difference the fact video stopped when the cpu > was not in the idle key press loop? There's quite a few differences between the ZX80 & ZX81. The ZX81 supported 'compute and display' thanks to its more 'advanced' video chip! The ZX81 was (AFAIK) the first use of a gate-array chip in a home computer! The ZX81 had an 8K ROM with floating point arithmetic, 'graphics'; decent string-handling and ZX printer support! The ZX81 syntax-checker was nicer. The ZX81 had a heat-sink that worked! The ZX81 was unbelievably slow! The ZX80 had that certain 'je ne sais quoi' that makes it at least worth 10x more than any ZX81. I'm convinced about this, being the lucky owner of one* ;-) -cheers from Julz @P * It was given to me as well, for which I'm really thankful!

Data General Eclipse MV/9000U available in Hayward, California

by sellam＠vintagetech.com

There is a Data General Eclipse MV/9000-U CPU (and cabinet/power supply if you want that) available in Hayward, California. Further model information is "G11202-G7". I don't know much about this. Photos here: http://siconic.com/crap/hayward/ Someone apparently dropped it since I last saw it. Don't know what damage has occured, but at least the photos give you a general idea of the size. My guess is if you want this you'll just want the CPU. It's in there...somewhere.

Non-Linear Systems Kaypro II available in Hayward, California

by sellam＠vintagetech.com

There is a very nice condition (excellent cosmetic/physical) Kaypro II (branded Non-Linear Systems, so it's early) available in Hayward, California. I've turned it on and booted it up and it seems to work just fine. The video is nice and crisp. It's a really nice Kaypro II, with minor wear. I believe it is missing one of the keys on the numeric keypad, but otherwise is complete. While it is not mine, I am selling it for the owner. Please contact me directly with an offer if you're interested. Will ship to anywhere. The same model sold earlier in the year at the ACCRC auction for a $151 high bid, FYI. -- 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 ]

by richardlynch3＠tx.rr.com

I was recently given an HP1000 A900 which I don?t have time to do anything with, so if someone wants it for the cost of shipping (it's big and heavy!), contact me offline. It has a CPU and 2 memory cards as well as several I/O cards (12005, 12009, 12040). It powers up and LEDs on the CPU card blink but I have no way to test it further. Richard

I/O chip for Bally Astrocade?

by derschjo＠mail.msu.edu

Ok, so it's stretching the definition of "computer" but it _does_ have a BASIC programming cartridge and it IS classic (1978) so I think it qualifies... Got me a Bally Astrocade that appears to have a dead I/O chip. From the service manual, this is a custom chip listed as PN "0066-117XX-XXYX"... I figure it's a long shot, but anyone out there have spare parts for these? I figure if anyone knows, they're on this list :). Thanks as always, Josh

NeXT pile for sale (Oakland, California, USA)

by sellam＠vintagetech.com

My good friend Robert Arnold has a very nice pile of NeXT stuff, including several complete cube systems with keyboards, mice, laser printer, scanner, etc. Photos available here: http://siconic.com/crap/rax/ Located in Oakland, California. Terms are pick-up only. I would imagine Robert MIGHT be willing to ship this if you ply him with enough money, but it would have to be a compelling amount (as in an amount that would be required to hire someone else to do it professionally). He simply does not want to hassle with shipping. The entire lot is for sale for $1,500. I think that's a pretty screaming bargain considering all that is there. He would also consider a partial trade for a recent vintage Macintosh notebook or desktop. More information below. Please contact Robert directly if you are interested.

Thanks! I am continuing work on the N8VEM S-100 projects. Currently I am working with some other people on S-100 related projects. I recently made a PCB manufacturing order for a group buy of N8VEM S-100 prototyping boards. With the larger quantity, I was able to reduce the cost per board to $18 down from $25 each originally. The next project is a joint project with another builder to make a different S-100 board (TBA) but not the uPD7220 board. I am still seeking basic information on the uPD7220 GDC and there is very little available. If you know where the uPD7220 User Manual and/or Design Guide are (paper or scanned), I would certainly appreciate some help in getting the information. I have the datasheet and some simple stuff gleaned from the web but that is insufficient information to design a full blown S-100 board from scratch. I am looking for some sample circuits to help with design and prototyping. Dan Roganti has (I think) a copy of the User Manual and is scanning it which should be available eventually. I can tell you with confidence after designing and prototyping the N8VEM VDU board, which was largely based on an already existing design, that video boards are complicated devices. Presently, I am working to build up the S-100 design skill set. Making S-100 boards is quite different than the ECB Eurocard designs I have done for the N8VEM project. Hopefully the third N8VEM S-100 board will be out soon and we can move on to more complex projects. I consider the uPD7220 design probably to be one of the more complicated designs so it will be a later project. I would like to do some simple boards like one each for parallel, serial, SRAM, RTC, etc. Maybe a debug board would be good depending on what is available. Eventually more complicated designs like a CPU board and/or graphics board. Given my skill set, available time, and tools the selection of projects is rather limited. Thanks and have a nice day!

road trip, truck space available

by mcguire＠neurotica.com

Folks, Starting this coming Sunday (10/18), I'm planning to embark on a road trip in a truck from SW Florida to Poughkeepsie, NY, then to Boston, then back through the Columbus, OH area. I will have LOTS of extra room (at least half of a 28' truck) on all legs of this trip. The truck has a hydraulic lift gate and I have experience moving big, heavy computer equipment. I can be bribed to move big stuff along this route, should that be of use to anyone. I'm looking to defray the cost of the trip for my employer, but if it doesn't cost any extra money (i.e., not too far out of the way and not too time-consuming) I can be bribed with Cool Stuff too. Also, if anyone along that route has any spare DEC H960 racks or RA60 drives (preferably functional) that they want to unload, I'd happily take them away. :) -Dave -- Dave McGuire Port Charlotte, FL

Largest ST-506 (MFM or RLL) type HDD?

by classiccmp＠philpem.me.uk

Hi guys, Does anyone know what the largest capacity MFM or RLL (i.e. ST-506/ST-412 type interface) hard disk was? I know the AT drive types go from 0 to 46 (plus user defined type 47), and the largest of these is #46: 1224 cyls, 15 heads, 17 secs (152MB). Question is, did anyone ever make an MFM drive that big, or was that strictly IDE territory? I know 80MB and 120MB IDE drives existed -- I used to have a Conner 120MB that was an utter pig to make work with any other drive, and I still have an IBM WDA-L80 80MB IDE drive. Thus far, the largest MFM drive I've found is the Micropolis 1325 (85.3Mbytes unformatted). Reason I'm asking is that I'm working on the seek logic for the disc analyser. At the moment, you can seek 127 cylinders at a time in either direction (there isn't a track-counter on the hardware, so all seeks are relative) and I was wondering if there's any point in increasing this further to accommodate drives with higher track counts.

N8VEM VDU board

by lynchaj＠yahoo.com

Hi! I just finished building and testing the new N8VEM VDU board PCB version. It is a 6545 based video board for monochrome character display on your home brew computer much like a KayPro 10 display. It works OK and provides a composite video display, PS/2 keyboard, PS/2 mouse and a parallel port printer interfaces. It is meant for the N8VEM SBC but the design is general enough it should be useable on most any Z80 style system. If you are interested in building your own and/or writing software for the N8VEM VDU please contact me. When the SBC, ECB backplane, Disk IO board and VDU are combined they offer the potential for a completely stand alone home brew Z80 CP/M computer. The software for the VDU is still in development and it There are pictures and code on the N8VEM wiki in the VDU folder. Schematics and PCB layout are available. I have several PCBs. Constructive comments welcome. Please no flames. Thanks and have a nice day! Andrew Lynch

I "need" two of these things at $121 a piece. So I figure I'll start ebaying some things to feed my habit. If anyone would like a working amiga 2000 with hard drive or a steel case commodore 128D, let me know. I'd prefer to make a deal with someone on the list than to put up with ebay. I also have three JVC TM-9U 9" studio color monitors with BNCs and RCAs on the back. thanks. brian

CRT Controller Handbook by Gerry Kane

Sorry, that's "Controller" not "Controllers" Hi! I seem to recall there was a scanned version of the "CRT Controller Handbook" by Gerry Kane online someplace. Does anyone know if that is true and if so, where? Thanks and have a nice day! Andrew Lynch PS, I already have the print edition but a scanned edition would be very helpful.

Reverse engineer the MatchPoint PC card?

by jhriley＠earthlink.net

I am moving ou of some office space I have occupied forty years and have come across a large cache of hard sectored NorthStar CP/M diskettes that I would like to obtain the data from, a daunting task. I have long wished to obtain a MicroSolutions MatchPoint board to try this before my diskettes decompose. Would you consider either selling me your board or loaning it to me for a fee? Inthe latter case I would return it to you with the .286-based computer I would have to build to access it. I am located in Southern California. Are you interested. They are hard to comr by.

looking for TU81(plus) UNIBUS interface module M8739

by henk.gooijen＠hotmail.com

Hi all, I recently picked up a TU81plus. It came with all cables, but the UNIBUS interface (M8739) was missing. The TU81 successfully passes diagnostic test 01. I would like to connect the TU81 to my VAX-11/750, and remove the (not connected) Kennedy 9610. I know ... the Kennedy is capable of more densities (800, 1600, 3200, and 6250) and is smaller (a lot). But the TU81 is original DEC ... So, does anybody have the M8739 module spare? May be we can trade something, else there is PayPal ... thanks, - Henk www.pdp-11.nl

Pretty sure I've seen the sources already on the net. Pretty sure I also have them somewhere. I definitely have TECO-8.

Looking for a punch-card reader.

by pat＠computer-refuge.org

As I didn't end up getting the OMR-2000 that ended on ebay yesterday, I'm still sort of looking for a punch card reader, preferably something that's functional, and that won't take too much effort to connect to a machine I already have (eg, one of the surplus Documation? 2000 election units). I don't have a big budget for this, or any REAL need, but I do have some cards I'd like to archive at some point from Purdue's old CDC gear, and of course who doesn't need to have a punch card setup laying around??

None of those has an original DEC label. Is there anything extremely important on them? Or are DECTape reels rare, uncommon and valuable? Any ideas? Regards, Philipp -- http://www.hachti.de

Any experience with or recommendations on restoring rusted galvanized steel?

by ethan.dicks＠gmail.com

Hi, All, Some of the equipment I have has been through the wringer before it got to me so I have a couple of items of unpainted, galvanized steel where the galvanization is gone in patches larger than your hand and the steel underneath has oxidized to black (not so bad) or red (not so good). At the moment, I'm dealing with a single-board-computer "base" and a semi-custom rack shelf that both need some help. I know I can treat red iron oxide (rust) with naval jelly, but then I still have bare steel with no galvanization. I'm not expecting to get a cosmetically perfect item, but is there a good way to restore/protect things like this, or should I just expect to paint the entire item (it would look strange to just paint the formerly-galvanized area). Obviously, descaling, sanding and painting is one way to deal with this. I'm looking for possible alternatives. Thanks for any suggestions or pointers, -ethan

Catweasel support for Intel M2FM working!

Everybody has to draw boundaries over what they're gonna try to do, and what they not try to do. I think it is reasonable for the Catweasel people to say they only log transitions on the floppy and that they don't try to do anything else. Other people can pick up where their expertise comes in. Details of file formats of every obsolete 12-bit OS is not something I would trust the Catweasel people to do in fact. I know of floppy disk formats that in fact are not in fact fixed sector size, they are more like a cassette tape filesystem where sectors vary in length as necessary. Remember Al, that's why we go for image files as the actual archive with everything else just an interpretation or display.

ASR 33 not horizontally spacing

by roger.holmes＠microspot.co.uk

Just a suggestion but I had a KSR33 which did much the same. There was a piece of thin flat (spring?) steel on the carriage which got broken. On doing a carriage return, the ratchet mechanism which normally moves the head to the right gets dis-engaged. When the carriage gets back to the left, the piece of steel pushes against an arm which re-engaged the ratchet, only on mine it wasn't.

ASR 33 not horizontally spacing

by billdeg＠degnanco.com

I knocked over my previously working teletype. After locating all of the pieces, I carefully re-installed as much I could. The whole thing came apart, little pieces everywhere. The typewriter became detached from the keyboard. Pretty bad. I almost got it working, but there is one thing that I cannot seem to fix. The problem is that the print head is not moving horizontally along the line, it just says in place and types each character on top of itself. I do know that the teletype is sending data correctly from the keyboard to the computer through the serial cable, and the computer is receiving the commands. Output from the computer to the teletype is received and the print head itself is printing the correct characters. The problem is that the print head is not being moved to the right/horizontally. I can manually move the print head while in a operation (I can send a punch command to the printout paper for example) and if I time it just right I can space out the printed characters manually so I can see what has been sent from the computer. Can anyone help identify the fix? I would be willing to travel to someone with experience who repairs these (w/i 250 miles of Wilmington, Delaware), we can talk offline about service fees/trades. I have a lot of spare teletype and other parts. Worst case I guess I will offer buy another stock ASR 33 if anyone has one and this one can't be fixed. Is there such thing as teletype repair in the Philadelphia - Washington DC area? Here are some pics, if they do any good. I can take more of targeted locations. http://vintagecomputer.net/teletype/asr33/2009/ Bill Degnan

TS-11 Fortran & overlays...

by neozeed＠gmail.com

Hi, I've been trying to build some of the old dungeon (zork) source files I've manage to find... I've bee using SIMH, and it's TS-11 v4 distro I found some Fortran stuff here: http://www.headcrashers.org/comp/rx01/ When I run SIMH, this is what I get for "show cpu" CPU, 11/73, NOCIS, idle disabled, autoconfiguration enabled, 256KB This is my ini file: set cpu 256k att rk0 rtv4_rk.dsk att rk1 dungeon1.dsk att rk2 dungeon2.dsk att rk3 asc.dsk I've figured out how to install the compiler from some PDF's and the test program will build. However when attempting to link dungeon I'm getting this error: ------8<------8<------8<------8< ?LINK-W-Undefined globals: CVTTIM GTIM $OVRH ------8<------8<------8<------8<------8< I cut out the references for CVTTIM & GTIM from the source, but the OVRH is not found... People tell me it's an overlay manager but I cannot find any mention of this thing anywhere as far as where to find it, build it link with it or anything..... I can provide more detail if needed but I'd really appreciate any pointers on this... TIA Jason.

Fixing a 386SX laptop

by thypope＠gmail.com

Hello everyone, My oldest machine is a Goldstar Gold Note 386SX 20 MHz with 2 MB of RAM. I'd like to do many things with it, but no matter what I try to do, at some point the screen starts going dark and then bright and then dark again...varying in brightness until you can't focus on what you are doing anymore. It's a grayscale LCD. Apparently no dead pixels at all. I've been told by someone who fixes motherboards and other things for a living that it's not the screen but something else. However, the man claims he has no time to look into the machine and find the problem. If anyone has any idea of what could be wrong, wether it is possible to fix it and hopefully how, I'm all ears. I will even send it to whoever can fix it and pay for the repairs, like I intended to do with this local gentleman. I'm very curious to at least hear what's wrong.

To clarify about VMS / MicroVMS versions I've looked into some VMS V4.x tapes and found out the following: Version Type Date written MicroVAX support V4.0 Full 23-SEP-1984 NO V4.1 Update <missing> ??

Distribution tapes were identical, whereas the RX50 floppy sets most probably were not (as to save space/floppies).

Reviving old environments (was Re: Free VAX/Alpha hardware)

Do you have a Qbus COMBOARD? ;-) I think one list member ever has piped up that they found a COMBOARD in a rescued system - we sold a few thousand Unibus "COMBOARD I" (HASP/3780) boards over 12 years or so, a much smaller number of Unibus "COMBOARD II" (SNA), and an even smaller number of Qbus COMBOARDs (HASP/3780/SNA), and by comparison, a microscopic number of VAXBI COMBOARDs (HASP/3780). If anyone still cared about setting up sync links between VAXen and IBMs, I'd have more motivation to work on these sorts of projects, but since I never have gotten the DWBUA working on my 8200 after it moved to my house, I don't really have a ready-to-use environment for testing our old Unibus products (of which I still have a couple tubs). Qbus is easy, as is VAXBI. It was a great product for the 1980s, but I don't really hear any buzz about sync serial comms anymore. -ethan

Old VMS distros (was Re: Free VAX/Alpha hardware)

That sounds right from what I remember. After that point, it became a memory/disk space issue, not an architectural issue. I don't recall when uVAX-I support was dropped, but I don't think VMS 6.0 is supported on an RD54 (though it _can_ be mostly wedged in there). > I'm still looking for the following versions: > > - MicroVMS V1.0 ( = MicroVMS V4.0 ???)

I have many of the earlier ones of those, on original media, though I can't guarantee what will read and verify from 20-year-old media. I will certainly give it an attempt. We had an 11/750 on software support from their initial release in 1983 through 1993, MicroVAXen from their release in 1984 through 1993, and an 11/730 that probably used the same media as the 11/750, IIRC. Some of our MicroVAX stuff was on RX50; some on TK50. We ran (u)VMS and Ultrix. I was able to save about 80%-90% of the distro media when the company closed (some of the earlier stuff may have been recycled since TU58s and RX50s were considered "expensive" and "why would we ever want that old stuff anyway). I do have a pile of DEC distro floppies for the Pro series that turned into backup and transfer floppies, so are decorative, but not functional now. :-/ Since I recently went through the exercise of creating a Compaq utilities disk for my Portable II, I'm in better shape to archive RX50s. I'll have to dig out my TSZ07 to image install tapes. I will not get to any of this before Thanksgiving, so please don't ask, but feel free to rattle my cage (offlist, please) if it's January and I haven't made a peep. If you need it sooner, I can't imagine that I'm the only person in the world who still has 15-25-year-old backup media - someone must have much of this stuff spun up somewhere (though I can undertstand not wanting to make it available all the time to random passers-by). -ethan

I'm honestly not expecting 100% success on reading them, but fortunately, the content is far from unique. As to how you might use them - I'd expect that you'd need a stack of RX50-formatted 5.25" floppies and the disk image files and an Intel-based PC running Linux (or perhaps Windows) to apply the image files to the physical media. Armed with a stack of floppies, you'd install VMS the way we did it in the old days - spending an afternoon feeding floppies to SABACKUP. I have many other things on my plate, so I wouldn't expect to get to this before the Holidays. -ethan

Chatsworth OMR-2000 opinions?

Does anyone have any opinions on a Chatsworth OMR-2000 as a punch-card reader? I've got some cards that I want to read in, and found this. The price is a bit more than I wanted to spend, but it looks maybe nicer than the ones that became surplus (Documation?) after the 2000 US election debacle.

"Imaging" a MFM drive?

by joachim.thiemann＠gmail.com

Hello, I have an old MFM drive (MiniScribe 8425) hooked up to a Xebec 1210C 8-bit ISA controller, pulled out of my Amiga 1060 sidecar, which used to be the system drive for my A1000 (still in fine shape, thank you, though the sidecar sadly isn't). The drive ought to have a 5Meg DOS partition and the rest Amiga formatted. Out of nostalgia and curiosity, I'd like to attempt to "image" the drive, to see if I can get at the old Amiga files. Any idea how this might be possible? I can get a hold of a 1998-era PC, mainly PCI but still with a single 16-bit ISA slot - but I have no idea if there is any software that can then get the bits off the drive. ISTR that the xd driver in linux was broken or removed, or is the card WD100x compatible? Can NetBSD talk to it? Will the 8-bit BIOS on the card work in a Celeron class machine? If somehow I find a sufficiently old PC, how can I get the data off the non-MS-DOS partition? FWIW, if you're in the Montreal/Ottawa region, and you can make an image of the drive for me, you can keep the controller and the card for your collection, and I could even give you a Sidecar with or without Amiga 1000 for your troubles :-) It is of course quite possible that both the controller and/or the drive have gone to silicon heaven, and might make nice wall decorations. Joe. PS. I'm thinking a A2000 with A2086 card would probably be a good way to get at the data. I have neither, only an A3000. -- Joachim Thiemann :: http://www.tsp.ece.mcgill.ca/~jthiem

Tetris (on buildings)

Hi, Although this video is old (uploaded to YouTube Jan 2007) I thought I would mention it.

XTIDE controller now available

by trixter＠oldskool.org

I wanted to let all of you know that the 2nd revision of my friend's PC/XT IDE controller is now available. For those of you not in the know, this is a way of using modern IDE hard drives in your 8bit PC or XT system. Works with drives up to 137G (your O/S also has to support it; 8.4G is way more common) and Compact Flash->IDE controllers too. CD-ROM support is likely coming eventually, but he has to write an entire driver that MSCDEX would talk to. They're being sold at cost: $30 for a kit to solder your own, $40 for a pre-built and tested card. These are not quite the end production unit, but darn close. Works in PC/XT clones, as well as Tandy 1000 series machines (anyone who knows how hard it is to get an IDE drive into a Tandy will appreciate this). They are also going to be building one that will fit into a PCjr sidecar someday. ;) Details are available on the last message of this forum page: http://www.vintage-computer.com/vcforum/showthread.php?t=12359&page=109 -- Jim Leonard (trixter at oldskool.org) http://www.oldskool.org/ Help our electronic games project: http://www.mobygames.com/ Or check out some trippy MindCandy at http://www.mindcandydvd.com/ A child borne of the home computer wars: http://trixter.wordpress.com/

Classic computers endangered!

I read an article today in 'New Scientist' entitled 'Innovation: Classic computers on the danger list' with Tom Simonite writing: "Pretty much every adult alive today has seen computers change the world, but we are doing precious little to celebrate the influence of the computers and software that created our society." Indeed! Are we failing to preserve the earliest part of microcomputing history? Will classiccmp.org discuss early ucomputers in 5 yrs., 10 yrs.?

Some DEC parts and a Sun-compatible CD-ROM drive

Two kinds of Apple Airport cards?!?

by ethan.dicks＠gmail.com

Hi, All, I had great success recently, wedging in a "Dell 1150" Orinoco-based 802.11b card into a CRT-based iMac. I'm having less success with finding something to fit a G4 cube that recently followed me home. While at first glance, the antenna connectors look the same in the G4 Cube and iMac, they are not. I'm rather puzzled by that, unless Apple happened to change connectors from one line to another. I searched around a bit, but didn't seem to turn up any stated differences on Apple's support site or on various fora that cover older Macs. Does anyone have any experience with various G3 and G4 Macs and Airport cards? Are there two "styles" with incompatible antenna jacks? Thanks, -ethan

N8VEM S-100 Prototyping Board PCB manufacturing order imminent

by lynchaj＠yahoo.com

Hi! If you are interested in getting one or more N8VEM S-100 Prototyping Board PCBs, I am getting ready to make a manufacturing order. Based on my current projections, I am estimating a single N8VEM S-100 Prototyping Board PCB will cost $18 each (reduced from $25 each originally) plus $3 shipping in the US and $6 shipping overseas. I will combine shipping to reduce shipping costs depending on final weight. Please let me know soon if you would like to join in the order. If more persons join the order PCB costs may be further reduced. You can see additional information on the N8VEM S-100 Prototyping Board at the N8VEM wiki: http://n8vem-sbc.pbworks.com/browse/#view=ViewFolder <http://n8vem-sbc.pbworks.com/browse/#view=ViewFolder&param=S100> &param=S100 Thanks and have a nice day!

8MM Tape drives

by teoz＠neo.rr.com

I hit the local recycler today and purchased a few tapes drives. Snagged a DDS3 external, DDS4 external, and a cool looking IBM drive that I was hoping might have been AIX. Turns out its an 8MM Mammoth 20/40GB drive (looks like ebay #290335147769). The drive had a couple AS/400 stickers on it and appears to be HVD (with terminator attached on the back). Are these drives pretty decent, reliable, and fast? I don't have any experience with them and grabbed it because I like collecting any kind of removable media drive I don't have. Turned it on (fan must be moving quite a bit of air by the sound of it) and the LCD went through diagnostics and then to a ready state with no tape so I assume its not DOA so far. Just curious what you guys think before I go looking for tapes and a cable to connect it to a HVD 68 pin card in my SUN U5. I assume Solaris 8 might know what to do with this thing, or PC backup software will work with it.

For an identification like that and possibly to find someone else with the same accelerator who can ID the missing parts, I'd try the appropriate sub-forum over on 68kmla.net. That's 68K Macintosh Liberation Army. Jeff Walther

PDP 14

by tshoppa＠wmata.com

> Does anyone have a PDP 14? Or has anyone ever seen one out in the "wild"? > If so, please contact me directly ;) The PDP-14 was not a conventional computer... it was what we call today a PLC (programmable logic controller). Very adaptable to ladder logic and a bit more. DEC was pretty swift in how they allowed the PDP-14 to be configured via a real computer (a -11 or -8). It wasn't the GUI of PLC configuration today or even of the 80's, but it was a good start. The overall model of PLC configured or monitored by a computer still holds true today, I think that DEC could have really taken this idea and run with it but the overlap between industrial control and computers even today is less than thorough. The computer geeks don't understand the industrial control and process engineers for the most part (thus the common misuse of Windows PC's where a PLC could do the job far better and without point-and-drool.) IMHO if you are interested in PDP-14 you must also be interested in early Modicon PLC's, which were far more common, predate the PDP-14, used core memory like the PDP-14, and which the PDP-14 was pretty much a clone of. I think Modicon was also a Massachusets company like DEC. I never used a PDP-14 but I always understood them to be very much like the core-based Modicons I used. Tim.

Help identifying unknown Mac SE accelerator

by derschjo＠mail.msu.edu

Scrounged a Mac SE motherboard+accelerator from a parts bin at RE-PC this afternoon and I'm trying to figure out what it is. Unfortunately it looks like a few parts have been scavenged (a crystal oscillator and a few chips, plus the 68030+FPU) and there's a loose wire on the underside. I can't find any markings that give away its identity. I have a few pictures up at http://yahozna.dyndns.org/scratch/mysterymac/. Anyone have any ideas? Thanks, Josh

And at least the HNF does not restore/run their machines, they don't even display them in a logical manner (and it's Paderborn, not Padaborn ;-)) OTOH our little museum has been collecting/restoring etc. for much over ten years now. And of course, almost everything on display is functional (people don't want to see dead junk, they are much more impressed by a demonstration). Christian There are 'many' private and public museums that not only preserve but keep working vintage computers in their collections. Two important ones come to mind:: 1) The First Computer Museum of Nova Scotia. It has Kenbaks which some consider to be the first microcomputer. 2) The Digibarn Computer Museumlocated a shoet distance outside Silicon Valley. Not only does this museum have an excellent collection of vintage machines but has an excellent web site to boot. There are some interested in vintage computers just as some are interested in vintage cars. The numbers are really not that large, in either domain, as far as this observer can determine. Yet we should do all we can to preserve old computing technology. History will thank us! Murray

PCjr NMI and 8253 Timer interactions

by mbbrutman-cctalk＠brutman.com

I recently wrote a ping utility for my DOS TCP/IP stack, and I wasn't satisfied with the 55ms resolution of the BIOS timer tick. I used the 'delay' function in the Turbo C runtime which gives me a processor loop that delays with 1ms granularity. I figured that I could call that and poll for the ping reply, and the number of calls would be the ping latency in ms. Testing of delay in a controlled environment shows that at least on my PCjr, it is off by 15%. My V20 processor might be part of the problem, although I'm not going to fix it. So I decided to dabble with the 8253 a bit. What a nightmare .. First, some observations on the 8253: - Mode 3 on the 8253 is not suitable for reading because of the way it counts down twice before triggering an interrupt. If you just latch and read the count you can't tell if you are on the first pass or the second pass before the interrupt. That's not good for timing. - Mode 2 counts down and generates an interrupt in a sane way, but generates a different pulse to the 8259 interrupt controller so I'd rather not use it. The BIOS initializes with Mode 3, and that is what I am sticking with. I decided to make timer 0 tick at a faster rate (64x faster), and in my interrupt handler I call the original interrupt handler at the appropriate rate to avoid speeding up the system clock. This works fine, even on the PCjr. Except for one case ... On the PCjr, if I touch the keyboard the machine screeches. And not its normal polite 'Go away I'm busy beep' either. The keyboard on this machine is wired to NMI instead of IRQ1, so it has higher priority than timer 0. The NMI interrupt is used to read the keyboard serial data stream and it uses timer 1 of the 8253 to record when the first bit is received. Timer 1 isn't used elsewhere, so that is fine. If there is an error in the serial data it sounds the system beeper, so timer 2 can get altered at any time making timer 2 unusable. Any keypress causes the screeching. First, I can't figure out why the NMI handler is having a problem deserializing the keyboard even if timer 0 is running fast. All interrupts are disabled, so this should be business as usual. Yet any keypress causes it to go nuts. Any ideas? (As a side effect the timings reported by ping start to look bad - the NMI is definitely taking up precious time.) Second, the machine becomes unstable. I don't care about getting bad timings because of keypresses, but this is far worse .. If I disable the NMI interrupt everything is perfect - but then you can't hit Ctrl-Break to stop pinging. (Yes, I have Ctrl-Break captured, and it works if I don't mess with timer 0 at all.) I don't want to have to shut off the keyboard entirely if there is a possibility of figuring out why the NMI is causing problems with a fast timer 0. Ideas? Thanks in advance, Mike

Some new pictures...

by hachti＠hachti.de

Hi folks, I recently tried out a service called "Picasa"... There you can now see some pictures of some stuff I've been in contact with the last few months. The people in Kiel have a giant collection of hardware. Their task is to compile a much smaller collection for a permanent exhibition. So much stuff had to go. And there's still more to go. The pictures are not up to date as their hall's layout changes every few weeks because of planning processes. I assume that most of the smaller items will have to go. Some of the stuff (i.e. masses!) that has not yet found a new home, will probably be subject to further negotiation, a flea market (auction?) in Kiel, and many eBay auctions. So now, look and see: http://picasaweb.google.com/iraeus/AFewImpressionsFromKiel With kind regards, Philipp :-)

Macintosh IIci cache cards

by spectre＠floodgap.com

My hungry, hungry Mac IIcis gradually eat through cache cards (about one every three or four years) and I'm down to a low stock again. If you have some sitting in your closet doing nothing and could possibly be persuaded to discuss their future, please send me a message off-list. You will make IIcis doing real work in my apartment very happy :) -- ------------------------------------ personal: http://www.cameronkaiser.com/ -- Cameron Kaiser * Floodgap Systems * www.floodgap.com * ckaiser at floodgap.com -- If Milli Vanilli falls in the woods, does someone else make a sound? -- rhf

FS: PDP 8/e (Seattle, WA)

by derschjo＠mail.msu.edu

So a couple of weekends ago I was down sick with the flu and one late evening when I couldn't sleep I purchased a PDP-8/e off eBay, having convinced myself it was a really good deal while only half-awake. Here's the thing -- I already have an 8/e; I have no idea what I'm going to do with /two /of them. Here's what I have -- a bare-minimum 8/e with 4k of core, the basic CPU set and a single Omnibus backplane. No top cover. Front panel bulbs all seem good. It works fine (as far as I can tell -- programs I toggle in run, etc), is very clean, and is in decent shape. (A few scratches on the front panel, but honestly it doesn't look that bad.) An interesting detail -- the front panel says "digital equipment international ltd galway, ireland" instead of the usual "maynard, massachusetts" herald. I'm assuming that means it's worth a million dollars. Think of the deal you'll be getting! I'm asking only what I paid for it, which is $650. (Or alternately, trading for something "cool." Always looking for an Altair or a Xerox D-machine... :)) I'd prefer local pickup (and I'll drive a ways to meet you) but if you want to arrange something with Craters & Freighters or something similar I can do that too. I don't trust myself to pack and ship this thing myself without breaking it (and that would be a shame.) I can take pictures if desired. Thanks, Josh
