The Handbook of DEC Handbooks - status report.

by kstumpf＠unusual.on.ca

A while back many of you helped me compile a long list of DEC handbooks. I want to publish a beautiful book about them and it would also be a collector's guide. Well our combined efforts needed both more information to complete the list and it also needed an authority to confirm the completeness of our list. To do this I contacted a number of people at DEC/Compaq and finally got to a Mr. Stephen Dougherty. He was excited about the project and told me to get back to him in a week. This would give me time do some internal exploring. That was 2 months ago. His mail doesn't bounce back so he must still be working for Compaq, but he isn't replying. Thus the project is on hold. My investigation did some good though. The photo-archivist at Compaq was about to finalize arrangements to transfer DEC's archives to MIT when I introduced them to the Charles Babbage Institute. It doesn't matter who gets the photographs as long as they are preserved, but at least now, with the advice and encouragement of the professionals at the CBI, we will hopefully discover that all sorts of other important DEC memorabilia will be preserved. Take care ya'all. ---------------------------------------------------------------------------- ------------------------------- Kevin Stumpf * Unusual systems * www.unusual.on.ca +1.519.744.2900 * EST/EDT GMT - 5 Collector - Commercial Mainframes & Minicomputers from the 50s, 60s, & 70s and control panels and consoles.

I have hundreds of PostScript fonts (I used to be in the printing business) and I couldn't find an exact match. However, PostScript fonts are just vector graphic descriptions, and I have software that can read those into a vector drawing package, so I just took Helvetica as starting point and tweaked it. The result isn't *exactly* right, but very close. You can have a PostScript copy of that if you want it... -- Pete Peter Turnbull Dept. of Computer Science University of York

IBM Optical drives... A few questions

by roblwill＠usaor.net

Hi! I just got two IBM Optical drives, complete with drivers, controllers, operator's manual, and service manual. Now for the questions: -Are there updated drivers for these drives? The ones that cane with it run the driver as a DOS shell, which takes up a bunch of memory, and slows down the entire computer (also won't work with Windows). - Does anyone have an ISA controller card for one of these drives? Both controller cards I got are MCA, and I only have one MCA machine (The Model 80 runs OS/2, and I don't have OS/2 drivers), which is a P70. I have the external drive (I got an internal and an external) on there, and it works, but no way of testing the internal (I was going to use it on my Pentium). - Sometimes, when I put in a disk, and try to read it, I get a "General Failure" error. I take the disk out, put it back in, and it works. I think there was a discussion about this before. Do I just need to clean the disks? -The drives that I have are 3363's, and the disks I have are 3363 200MB Single Sided cartridges (IBM). Can I use other types of Optical disks, or do I have to use the IBM 3363 ones? Last question (for now...) I've heard (I think it was on this list) that the 3363 is a WORM drive. However, it allows you to delete files, but you don't get any added space when the file is deleted (as if the file is still there). If the file is actually gone, where did the empty space go, and is there any way to get it back? Or is the file still there, and it being 'deleted' is it just an optical illusion (no pun intended)?

What's a "computer console" selectric called?

by go＠ao.com

Back in the days before "glass" consoles, computers often (if they had them) used typewriter devices as console input and output stations. Many minicomputers used Teletypes, but Control Data used (believe it or not) IBM Selectric typewriters. (You can bet THAT stuck in someone's craw...) This was the case on the "lower 3000" line (3150, 3200, 3300, 3500) and I believe it was the case on the sister line of "upper 3000" (3600, 3800) systems as well. On the 3300 system, the console typewriter was a "drop in" unit with a small number of cables connecting it to the system. It dropped into a well on the console operators station and sat in this well on little rubber feet. Think of a "modern" Selectric with the top of it's case only; the lower part of the case was omitted and surrounded by the "well" it sat in. For a "vintage-like" construction project, I'm trying to locate an example of this console device. It needs to be working (or repairable.) The choice of type font is unimportant at this point. I've considered picking up one of the inexpensive Selectric or Selectric-II typewriters (don't need no stupid correction mechanism) and "converting" it to operate as said console device. However, I helped a guy do this conversion once (many odd years ago) and it wasn't pretty then and doubt it would be pretty now. And the conversion didn't cover the "input" side of the equation at all. It was just a printer. Does anyone know where I can get a unit such as this? If any of you have such a thing, I would be interested in purchasing and/or trading. Contact me offline if you want to arrange a deal. If any of you have pointers to places selling these sort of things, please let me know. I've mined all my usual surplus haunts and have searched the net considerably but have yet to come up with anything "right." Thanks, Gary

Centronics 739 printer

by pete＠dunnington.u-net.com

Amongst my collection is a Centronics 739 printer, which needs a new EPROM (the old one is corrupt). Needless to say, Centronics have no parts for a ~1980 printer, so does anyone here have one I could a get a dump of? Unfortunately, my collection of "useful ROM images" has only the 737 version (almost exactly the same, but without the graphics capability). -- Pete Peter Turnbull Dept. of Computer Science University of York

Space, the next frontier

by edick＠idcomm.com

No, but they do take up less space. Consequently, I've been pulling out the hard drives and the power supplies. The power supplies make a decent brick substitute and the drives have enough high quality scrap aluminum in them to pay for the XT and a cinder block.

In other words, the 'seek time' (really the >head switching time) was very small, but none-the-less measurable. True, but of no consequence as long as the head switching time is less than the time it takes to spin through the intersector gap. According to my RS03/04 docs, there's enough time to make such a switch between sectors. What I always found interesting about the RS-series drives were the write-protect switches. You can set six on/off switches to the binary number specifying the highest (of the total of 64) tracks that you want write-protected. -- Tim Shoppa Email: shoppa(a)trailing-edge.com Trailing Edge Technology WWW: http://www.trailing-edge.com/ 7328 Bradley Blvd Voice: 301-767-5917 Bethesda, MD, USA 20817 Fax: 301-767-5927

Compupro computer questions

> I picked up a Compupro 816 computer yesterday and an external drive unit >with a hard drive and an 8" floppy drive. I haven't brought it home yet so >I haven't taken more than a quick look at it. Can anyone tell be about the >computer and drive? What CPU, speed, etc. What kind of operating system it >uses, etc. If it's using the same CPU's it shipped with, it has a 8085A and a 8088A on a 85/88 CPU board. Speed is 2 or 5 MHz, depending on what the big red switch labeled "SPEED" on the CPU board is set at. Of course, it's a S-100 box, so just about anything could have been dropped in at either the factory (special-order), the Compupro dealer, or by the end user. Typically the system either ran CP/M-80, CP/M-86, or a special Compupro version that was basically CP/M-86 but would also run 8-bit executables on the 8085. There were many aftermarket CPU's available, some with 80286's on them and 8 MHz Z-80's, that were commonly dropped into Compupro chassis. > I don't see a keyboard or video connectors so I assume it needs >a terminal to talk to it. Very likely, yes. Most likely, it has a System Support 1 board with console serial port, clock, and interrupt controllers.

It's plain old RS-232. Depending on which OS and version you run, and how it was generated, you might need to assert DTR. > What size is the hard and floppy drives You tell us :-). A Compupro 816 most likely shipped with a Qume Datatrack DSDD 8" floppy drive, a bit over a Megabyte, most likely hooked to a Disk 1 (or 1A or 1B or 1C) controller in the S-100 chassis. The hard drive is likely a MFM drive, anywhere between 5 and 30 Megabytes, hooked to a Disk 3.

One other item of identification is that the gold top cover has a pipe sticking out of it, which is curved and of diameter about 1.5", and to tell you the truth, I thought this paperweight was some kind of blower or air conditioning unit.

The base is grey metal, perhaps aluminum, while the top cover is gold in color. Now, this item has a layer of what appears to be a foam material which provides a seal between the base and top cover, and out of one side come five cables, four with ribbon cable and end connectors marked W033, and the fifth with a round cable and an unmarked connector.

I have my (fairly small - mostly standard desktops) collection housed in my basement. I have a fairly large drafting table (workbench), with cement blocks near the back (on top). I have 3/4" plywood shelves, 3 levels high. The first and second shelves are computers, and all the monitors are on top. They've been like that for tow or three years, now, with no problems. The only downside is that the cement blocks get to be pretty heavy. They're not bad for a garage, though, if you don't plan to be moving them. They're easy to find at demolition sites, too. I got mine for $1 a block. ///--->>> -Jason Willgruber (roblwill(a)usaor.net) ICQ#: 1730318 <http://members.tripod.com/general_1>

<Check the quality of the decoupling capacitors on that board. A lot <of noise can be caused by low grade decoupling caps. If in doubt replace <them with speedy MKM-type 100n caps. Would not help the ram card. Could even make it worse as the power and ground gridding is part of the problem. <Putting the board in a slot near one of the terminators may also be <helpfull. < <Does this machine has active termination on the bus? Standard NS* horizon does not have any termination passive or active. Most work fine without it but I happen to have one that is a bit more stubborn. Though the NS* 64k dram installed works fine without termination on the bus most everything else wants it. Odd as I have another that never had termination! Allison

Peer-to-Peer under OS/2 Warp

I'm trying to set up Peer-to-peer network among my classic computers. Most of my computers run Dr-DOS 7.x with the network package, and the network cards work in them. My problem is my server...

<>Common mod, mine has it too. < <Mine wasn't the most neat, ic's soldered on top of others, etc. Did it the same way, though I was somewhat careful in assemble so it was rugged. <I built the Bit Boffer from the March 1976 Byte.

VCF 3.0 ANNOUNCEMENT: VINTAGE COMPUTER FAIRE!

<So I would be penalized for getting my SWTPC CT-1024 video terminal to wor <and enter it?

I found the 60Hz line sync BIT boffer, Kilobaud. common enough and aimed at CT1024. The 60hz sync was a component problem and once the offending pot and cap were replaced I found it to be very stable. <didn't work right, so took it out. Lastly, I added some graphics display i <parallel to the characters. Now 20 or so years later, it doesn't seem to <work, and the "original" ic's are all soldered in. likely forgot how to turn it on. ;) Seriously, the VFC Vintage criteria if applied as it is to old cars a chopped and decked 49 Chevy is a valid entrant even if the engine is a later model. The key is it's not catagorized as stock/restored. Like Tim said, nont one member of LICA has a "pure" machine. Some part was non stock and often the reason was price or availability. I can't say how many Altair and IMSAIs with floppies from neither vendor were seen. If anything a pure machine was more the TRS80 era or later when a vendor would actually sell all the desired parts.

Tek 31 calculator

by russmiller＠jps.net

Sellam, I've got a manual which could be scanned - It has one of those plastic comb bindings (Acco?) which needs replacing anyway. I think it is original since the cover is the typical Tektronix type with the cutout window that shows the title page. I can make a copy, or possibly loan it to someone local (Sacramento|Bay Area) for scanning. I was planning to bring the calculator and manuals (operating+statistics) to VCF to look for an interesting trade.

TCPIP via ethernet under DOS? (I know that is possible...but!)

Here are my thoughts on your need: -----Original Message----- From: jpero(a)pop.cgocable.net <jpero(a)pop.cgocable.net> To: Discussion re-collecting of classic computers <classiccmp(a)u.washington.edu> Date: Friday, May 21, 1999 9:51 PM Subject: TCPIP via ethernet under DOS? (I know that is possible...but!) >What s/w is needed to do the ip polling to gather in ip numbers on >outset of connecting to cablemodem? The s/w should consist of an interrupt driven device driver for the NIC, with any interrupts providing for input servicing. Now, this device driver should also provide the transfer of processor control to the IP layer. So, my suggestion is that you start with the NIC software. Under DOS you should also be able to implement the IP stack by extraction >from LINIX, or some other UNIX variant. Sure, there is bound to be a lot of modification work that you will have to supply to the code you "steal" from LINIX but, since DOS is a pseudo-lookalike for UNIX, it should work easily. William R.

The A3 board, <which was available also as an upgrade to the A2, has alot better noise <immunity. That too! ;) I found the NS* I have was real cranky with a compupro Ram16, so for an experiment I pull the bus terminator from my CCS crate and all of a sudden all the crankyness is gone. This is something I never saw in my other NS* and the are identical save for mine was hand assembled by me and the one I'm working on is definately factory assembled. Allison

VCF 3.0 ANNOUNCEMENT: VINTAGE COMPUTER FAIRE!

Replacement parts must be indicated to > the judges by the competitor. New old stock parts will be > considered to be replacement parts with a lesser point > deduction. A reproduction can not receive full points in this > category. Interesting set of rules, with an interesting sense of "purity". In the real world, of course, someone who bought an IMSAI and populated it with only IMSAI peripherals was a fool. And it also leaves out the richness of computing that is (was) possible - take a look in the back of a late 70's BYTE and you'll see hundreds of manufacturers making a huge variety of S-100 boards. Yet any computers demonstrating this richness, so important in the early personal computing industry before the dominance of the PC-clone and the subsequent dull monotony of compatibles, lose points in this proposed judging scheme. Oh well, different strokes for different folks. -- Tim Shoppa Email: shoppa(a)trailing-edge.com Trailing Edge Technology WWW: http://www.trailing-edge.com/ 7328 Bradley Blvd Voice: 301-767-5917 Bethesda, MD, USA 20817 Fax: 301-767-5927

Northstar Horizon Update

by edick＠idcomm.com

Seems to me like last time I took one of the classes leading to "ESD Certification" the standard resistance for "primary packaging," which is what encloses and otherwise directly contacts the packaged items, was 1 MegOhm per inch. That is high enough resistance that you can't hurt yourself with inadvertent contact with the AC mains, yet low enough to dissipate static from the usual sources with little risk to the components.

Atari help

by a2k＠one.net

Hello, I've been playing with my Atari 800 a bit, and the frustrating thing is I can't get the disk drive to work. When the drive is on and with a disk in it (is spins itself up alright) and turn on the computer, it doesn't try to read the disk (my last Atari, and 800XL I think.. did). In BASIC, any disk command (XIO, open, load, save, etc) give me an error that I looked up and means something to the effect of 'drive not present'. I've tried several utilities (myutil) on my PC to write the disks with mydos or ataridos, but I don't know if they're working as I can't write or read any disks. Any ideas, please?

<The "prefab" steel-and-particle-board shelf units available out there <are excellent deals. Easy to set up, easy to knock down, easy to move, <and they don't cost any more than the raw materials would cost you if you <decided to roll it entirely yourself.

Yes there are, Grainger is never cheap though. As someone that has done considerable wood work, Pop was a carpenter, I know how to buy materials and use basic tools to make nice looking stuff. Anywho, for 80$ I'd build a long wall of wood racks. Why? The average racks are way overbuilt. Using 3/8" or maybe 1/2" plywood or OSB is good and 2x4s for uprights are adaquate but 1/2 or 1/3 pine straping is good for the rest and very cheap. If carefully done using screws appearance and disassembly should not be a problem. Allison

Then I would think that portability and movability would be even more important considerations. The "prefab" steel-and-particle-board shelf units available out there are excellent deals. Easy to set up, easy to knock down, easy to move, and they don't cost any more than the raw materials would cost you if you decided to roll it entirely yourself. And there are a lot of brands available other than Gorilla. Take a look in the Grainger or MSC catalogs to see a really wide range of choices. -- Tim Shoppa Email: shoppa(a)trailing-edge.com Trailing Edge Technology WWW: http://www.trailing-edge.com/ 7328 Bradley Blvd Voice: 301-767-5917 Bethesda, MD, USA 20817 Fax: 301-767-5927

good excuse to run classic computers

by jim＠calico.litterbox.com

Here's a thought. If you've got classic computers you'd love to run but can't think of anything to DO with them, (and they speak unix) go to http://setiathome.ssi.berkeley.edu and make your computer's idle cycles part of the SETI search for extraterrestrial life. They download you a chunk of data from the Arecebo radio telescope and your computer spends its idle time running analysis on that chunk, then sends the results back. They keep track of what platforms people are using too. Wouldn't it be cool if the machine that finally found a real ET signal turned out to be a Vax 11/780 sitting in some collector's garage? They also have it as a screensaver for mac and windows, too. For reference, a "work unit" - about 300k of data all told - will take about 20 hours to process on my PII/300 machine assuming I let it run continuously. -- Jim Strickland jim(a)DIESPAMMERSCUMcalico.litterbox.com ----------------------------------------------------------------------- Vote Meadocrat!

IBM available...

by jlwest＠tseinc.com

A company I do some work with just showed me their old system that they want someone to cart off. From what I saw (and I'm not familiar at all with somewhat recent IBM's), it appears to be a system/36. There is a floorstanding deskside size cpu enclosure, two or three smaller enclosures (same dimensions as cpu except about 8 inches tall), and a system console with a really huge base on it. IIRC, the system said IBM 5655 or something close to that on the front. They swear the system is in full working order. I have no interest in this period of IBM so.... It's in St. Louis, MO, USA if anyone is interested just let me know via email. Jay West

TK70 cartridges?

by cmcmanis＠freegate.com

Hi Everyone, I've got my TK70 up and running on my uVAX but haven't been able to find a lot of cartridges for it. Several TK50 carts, but no TK70. Imation stopped producing them! So if you know anyone who is decommissioning a large VAX installation that might have a few dozen of these let me know. I'm interested in keeping the media alive for a while at least! --Chuck

I prefer Gorilla racks. I've bought/installed some of the plastic units out there, and find two severe problems: 1) most have shelves that are NOT simple flat surfaces. Instead, they're often some kind of exposed honeycomb (or other grid). This has two drawbacks: (a) if you put small parts on the shelf, they can drop through; (b) you can't slide units that have legs or other protuberances. 2) the "heavy duty" plastic shelfs that I've used (Rubbermaid?) start to bow under the weight of some computers Stan

Breathing new life in laptop batteries

by fauradon＠mn.mediaone.net

Hi, Thanks for all the info. Apparently there are no reliable way to bring their youth back, I would like to have a reliable laptop with a battery that last more than 30 min. I found a Zenith z-star 433 VLp (500 Mb hd, 12 M RAM and color display and the Zenith J-Mouse!!!) that I'd like to use while away >from home. The batery I got seem to work for a while. Also it has four contacts does this means that it provide mutiple voltages or is there some kind of charge sense signal? I haven't brought the battery to the bench yet (no room on or near the bench:). Also the pack seems to be sealed pretty good, any elegant way to open it up and reclose it without too much damage? Thanks Francois PS: I actually got 3 of these laptops and built two from the set of parts and two of the batteries are totally shot: they get very hot when I try to charge them and of course no juice is coming out. I can practice on one of the dead ones. >> >This is the beast bet as cells fail with internal shorts and the cap will >> >dump enough energy to open them without cooking the cell. >> > >> Yes, but many times in my experience another short appears shortly.

Collecting PCs

by cmcmanis＠freegate.com

The general disdain with which PC collecting is met with on this list is understandable, however, I have been thinking there must be something here. I recall the folks who have collected PETs and C64s that are pretty common and "worthless" these days (I saw a new Vic20 in box at the Hamvention that they couldn't _give_ away.) So I've had some thoughts on what might be useful to "collect" when it came to the PC industry and this is what I've come up with: 1) All motherboard types - collecting one each of the "standard" sizes (AT, XT, Baby-AT, etc) 2) Collecting one each of all processor types. 3) Collecting one each of all media types. 4) Collecting all of the video standards. 5) "Famous brands", IBM, Compaq, etc. 6) "Famous peripherals", Bus mouse, XT keyboard, AT keyboard, etc This is something that anyone could start today since, like the computers of yore, this stuff is currently being tossed out. Comments? --Chuck

VAXStation/MicroVAX 2000 stuff

by donm＠cts.com

About a week ago I was exclaiming my good fortune in being able to have my VAXStation 2000 recognize a plain-vanilla Maxtor XT-2190 as an RD54 and proceed to format it. My concern being that if it did not recognize it, I did not know where to find the data required. I have since found it on www.vaxarchive.com. My intent in formating the 2190 was to install it in my MicroVAX 2000 and have a sort of 'matched set'. I am a bit sadder and wiser now that I have discovered that the MicroVAX is missing a rather large daughter board that resides beneath the motherboard in the VAXStation, and apparently carries the HDC and SCSI controller hardware. This seems to leave using the MicroVAX as a satellite unit to the VAXStation as the only alternative. Tried this, and MicroVAX tried to boot from ESA0 while cabled to the VAXStation, but no-joy. Is the problem that of not having things set up for cluster operation? If so, how do I do that? Keep it rather basic, please. I am pretty ignorant about all this. - don

I got my PDP-8E for free (PDP-8E cpu, box of spare cards, TU-56 tape drive, Paper tape reader, and a lowboy rack). Not only that, but the collector de-racked and loaded the system in his truck by himself, and offered to drive half way to meet me. I would suspect that this meets anyone's definition of free (ok, so I spent some gas money for me and him and bought him lunch). This system is one of the most treasured in my collection. I have spent many months painstakingly refurbishing the machine to factory new condition. So, I have to say that people *DO* value the things they get for free. Heck, the fact that I got it free makes me value the thing more than if I'd paid real cash for it, at the very least because if evokes fond memories of that day of pleasant historical computing conversation with the donor. And - that is not the only example. A truely kind soul on this list (to whom I am eternally gratefull) sent me an HP2108A cpu and PDP-8E 8K core board for simply shipping charges. There are many other examples. At the very least, since I have received this treatment from others there are times I have already sent out items for free, and there will likely be others in the future. That doesn't mean at ALL that I don't value them. Jay West

VAXStation/MicroVAX 2000 stuff

by allisonp＠world.std.com

<OK, the MicroVAX has the main board which is mounted solder side up. It <also has the extended memory card, a Network(?) card that connects via two Yes the LANCE chip (NI) is on a smaller paddle board. <40 conductor ribbon cables. What is missing is the large - almost main <board size - board that is situated component side up beneath the main <board, and connects to it via two 40 pin headers (that run parallel to <the 50-pin and 60-pin connectors for tape SCSI and hard and floppy drives <respectively) on the main board. Is that the Video Extension board? Yes. Without it you have mono video or you can run using a serial terminal via the printer port as console. The connector if pin 8 or 9 is grounded tells it to use serial port instead of the video console. I've hard jumpered mine so I can boot and run headless or use a more common cable if I want a serial terminal on the system. the 50 pin is the SCSI the 60 pins is HDC and floppy and the other larger board is the video extension. Without the video board they are the same beast. <Does the position of the Berg jumper about two inches from the rear of the <BNC connector affect the functioning of the storage devices? No. The storage devices are always available if the system probe finds them. It's possible to have a RX33 floppy(TEAC FD55GFV), MFM hard disk, A second RD5X MFM and TAPE(TK50) via a SCSI bridge. NOTE: the scsi is real SCSI hardware wise but the roms(and VMS drivers) do not implement compatable SCSI protocal so the only standard device is the oddball TK50. The SCSI oddity is from the mid 80s when SASI/SCSI was not a clear standard. For hard disks RD54 is the most desireable but v5.x can be trimmed to fit on a 71mb RD53 (DECwindows has to go,as I've got one here that way). Terminal support is via the DB9 printer port. If you can find one there is an adaptor P/N70-23766 that converts the video connector and the printer connector to three RS423 MMJ serial ports. I run all my VAXen to serial ports and a VT1200 DECterm, can't spare the space for the usual VR260/290/320 or larger tubes. Since DECnet does the equivelent telnet (and then some) one or two tubes are enough for support and talk to all of them. Hope this helps. I happen to have three of them, two running VMS and one with Ultrix4.2 on it. To that two MicrovaxIIs, 3 MV3100/M10Es, 1 MV3100/M76 sharing the eithernet with two MS PCs and a Linux PC box. Allison

It wasn't an RS6000 but used an M68020. The family name was DPX/2 and models no's went from 210 to 380 In the company where I work we are still running a DPX/2 380 under B.O.S.IX The machine was the last one that used the Motorola 68000 family. If I remember correctly, 2xx family was monoprocessors while 3xx where multi; DPX320 and DPX360 used 68020 and 68030. Ours (380) has one 68040 at 25 Mhz but could accept up to 4 CPU. ------------------------------------------------------------------------ Begin [OT] corner about price policy and machines sizing The funny (or sad) about that is that the expandibility offered by those machines are always not a good policy: After 3 years (1995) from the installation date, I decided to check the opportunity to upgrade the machine with another cpu. The official price was 21 million lira! (Abt 12 thousand USD) that was nearly the current price for a new system with a Pentium class processor: instead of adapting the price to the current market value price, they keep (or increase) the pricelist, probably to better convince them to change earlier the machine. I believe this policy is widely spread between constructors of propietary architectures machines. Now since the old DPX wouldn't see the lights of the new year in a sane condition, I'm quite indecided between the purchase of an entry level machine (you keep it 3-4 years then change without upgrades) or just a step further, with 2way processor capability. Do you have any personal experience on that?. End of [OT] corner ------------------------------------------------------------------------------ Coming back to DPX family...well before the IBM collaborations (and shares exchange) on the PowerPc architecture, Bull released a contemporary line machine based on a RISC processor that still used BOSIX. Again the name was DPX/2 (cannot remember models name). After this model Bull came out with Estrella and Escala PPC machines. Some machines where developed by Bull and manufactured by IBM for both labels, some were developed and made by Bull. Ciao Riccardo Romagnoli <chemif(a)mbox.queen.it> I-47100 Forl?

Apple Monitors ??

by owad＠caesarville.net

>One other question: What was the RGB port on the //c used for? Was this >for a high-resolution color monitor or what (other than the LCD panel)? Actually, I don't believe its an RGB port. According to the manual, the little icon above the port represents "Color TV". The port is used to connect an RF modulator. I recall reading that the only way to get RGB monitors to work with a IIc is via a composite-to-RGB adapter, which had not yet shipped by the time the book was published. While we're on the subject of video for the Apple IIc, does anybody know of any inexpensive composite LCDs that'll work the IIc? (Note that "inexpensive" rules out Apple's display.) Tom Owad

Geez... I can sympathize with you, Sir Wirehead! Seems you aren't the only person here with the "wish I could remember not to post personal crap to the list" blues... I did this right after I read your post about it! Dummy me even copied the correct email address into the clipboard... just forgot to past it into the To: field! Sorry, for I are dumb. Roger "Merch" Merchberger -- Roger "Merch" Merchberger --- sysadmin, Iceberg Computers Recycling is good, right??? Ok, so I'll recycle an old .sig. If at first you don't succeed, nuclear warhead disarmament should *not* be your first career choice.

VAXStation/MicroVAX 2000 stuff

It's pretty easy. CLUSTER_CONFIG is a very friendly program, prompting you along the way. You'll need to know the Ethernet address of each satellite and establish some DECNET numbering scheme for your satellites. The hardest part is thinking up six-character node names for each node :-). Running a VMSCluster is very easy - it's only slightly more difficult to administrate a cluster of several hundred nodes than one node. Compare this with running a few hundred Linux or Windows boxes, a task that takes an army of administrators. -- Tim Shoppa Email: shoppa(a)trailing-edge.com Trailing Edge Technology WWW: http://www.trailing-edge.com/ 7328 Bradley Blvd Voice: 301-767-5917 Bethesda, MD, USA 20817 Fax: 301-767-5927

Any error messages on the consoles? You never say what OS you were trying to use, but I assume it's some version of VMS. You can login to the VAXstation as operator (or someone with equivelent bits) and run REPLY/ENABLE, that would, iirc, make the VAXstation log information to the console about clients requesting load images (and much more ofcourse).

Does anyone know a source for a fairly cheap monitor for an Apple //c and a color monitor for a Mac ][? One other question: What was the RGB port on the //c used for?

SoCal TRW Swap 29th

by jpl15＠netcom.com

The monthly Southern California TRW Ham Radio and Electronics Swap Meet is being held this month (May) on Saturday the 29th, from 0730 hours to 1130 hours local time, at the TRW facility in El Segundo. Take the san Diego (405) freeway, exit Rosecrans, go West about 1 mile to Aviation (under the Metrolink bridge), turn left (south) on Aviation and proceed 1/2 mile south. The TRW facility will be on your right, and the Meet is held in the southernmost parking lots, bordering on Marine avenue to the south. Find a place to park and come join Marvin and myself, although I will certainly have gotten all the choice goodies first, (unless Marvin beats me to them). I am in spaces J21 and J23 and any classicmpers who will be in the area are cordially invited to join us. I have space available for anyone who might wish to unload some ju^H^H^H^H vintage items on the swapmeet attendees. There will be the usual after meet Brunch-n-Brag, at about 12:30 at a restaurant local to the swapmeet; all are invited. I am considering another collection Open House at my place, but that depends on feedback. E-mail me privately for further information/data/whatever. Cheers John

I didn't mean modern like IDE disks, though that's an idea. I meant modern for the PDP-8 in general (RL8A/RL01, RK8E/RK05 vs DF32 and RF08).

Scientific Micro Systems

Regardless of the physical size, (maybe 13x15") if they are FT400 or FT300 models, then I may have useful information regarding their use. These models are FDC-only with a very easy programming interface. Back when I used a 1 MHz 6502 for much of the work, I used one of these and was probably the only one around with double-density capability as a result. The interface was dirt simple, yet could keep up with any processor of the time.

Amiga A1020 5.25" floppy drive (was Re: Atari modem)

by gregorym＠cadvision.com

It can be done, but I don't remember how. A lot of my friends transitted >from C-64s to Amigas, and at least one of them had hardware that let him connect the 1541 directly to his Amiga to do file transfers. I don't remember if it was just a cable and some software, or if there was a hardware interface involved. A quick post to comp.sys.amiga.hardware should find someone who remembers. Regards, Mark.

plated-wire memory

by yakowenk＠cs.unc.edu

How similar is plated-wire memory to core? Does it have the same wire-matrix organization, but is dunked into some magnetic gorp rather than having little torii strung on? Bill.
