by mhstein＠canada.com

With all this talk about 286 PCs, anybody interested in an ALL Chargecard hardware memory manager to turn your PS/2 50, 60, or 30/286 into a 386 (sort of)? Only fits PGA, no LCC or PLCC adapters; brand new, never tested (didn't/don't have a PGA 286 board). mike

OT: Earthlink customer support

by vaxman＠earthlink.net

I got my first invoice from Earthlink yesterday for two months worth of service. The only problem was I didn't have the modem for the first two weeks of it, so I thought I shouldn't have to pay for it. I sent an EMail to Earthlink explaining the situation, and requested a credit of $12.99 for the unused portion of the month, and they replied today with the information $13.00 had been creditted to my account, and an apology for the inconvience it caused. <WOW> Clint is happy today... PS If anyone wants to switch to earthlink, mention my email address and I get a referral bonus, to be repaid in spare bits of junk er um antique computer parts :)

They were either 99p or 199p each from CPC. IIRC they were on one of their special offer sheets that they send out to account customers every weekend, about 18 monthsor a couple of years ago. Probably a one-off special as I don't see them in the catalogue :-( The transistor one is about 5/8" thick, 8.3" wide x 5.8" high, and it says "'97 The Transistor Manual" on the front in Eglish, and something in Japanese underneath.

Stuff I want to get rid of...

by rschaefe＠gcfn.org

Got some misc stuff I don't want. A few boards pulled from an old PBX: One marked `LC 96B V 1' and `SYSTEM CONTROL', one marked `LC 78B V 1' & `PROCESSOR' (AMD 8080A CPU!) & one marked `LC 95C V 4' & `MEMORY 1' (two banks of 9x uhhhh 1484?, one bank of 8 wide ceramic 24 pin DIPs). The dang thing weighed a ton, so I couldn't get the whole chassis, but I pulled the more interesting cards. One Sperry PC 384KB memory upgrade, new in box, (handwritten) serial # 47y791. Yours for shipping from zip 43211, or it goes to the trash. ja ne! Bob

>BTW, does anyone know if there's an internal adjustment to brighten these >up? It seems that a lot of the surviving NeXT mono screens have gone quite >dim. > >Thanks, >Arlen Michaels I believe that there *is* a pot inside that can brighten the monitor, but I also believe that this is a common and well-known (at least on the NeXT news groups) problem with the original monitors: they eventually get very dim--more or less too dim to use. This happens, I seem to remember, after only about 5,000 hours or so. It is a function of the phosphor, it is not prevented by dimming the monitor, and it was rectified in later versions of the monitor. (The details behind all of that information escape me. I suspect you could post a request at comp.sys.next.hardware, and you'd get a reply from someone who knows it all right off the top of his or her head.) Good luck! PB Schechter

Since there are a few people into the NeXT machines on here, I wanted to offer this here. I've got an extra N4000A monochrome monitor that I wish to get rid of...and it's FREE! The only problem with it is that it is dim. Otherwise it works great. I've got another N4000A and a N4001, so don't need this additional monitor. Drop me a line if interested. It's just outside of Washington D.C. I'd hate to just dispose of it if nobody wants it but I don't have room enough for all the machines I want, much less extra monitors for all of them.

68010 (was Re: Mac IIci)

by GOOI＠oce.nl

Indeed, the 68000 and 68010 pushed the same amount of data onto the stack, but the 68010 produced more different types of stack-frames than the 68000. If you wanted to speed up the ATARI-ST you could replace the 68000 with an 68010, but you needed to patch TOS. Otherwise the O.S. crashed. Nice was the fact that the 68000 and the 68010 are *pin-compatible*. I know, because my StarShip first ran on a 6802, then a 68000 and then on a 68010. I had to re-write a small part of the embedded OS that handles the stack-frame processing. Tight-loops (2 instruction) are cached.

IBM R390 IPL woes...

by out2sea00＠yahoo.com

Dave -- I appreciate you're coveting... but the system's not mine to give. It belongs to CSC, and was left-over >from our Y2K group. They had just stuck it in a closet and forgotten it. As the resident UNIX guru at the time it was on my inventory. When I moved out into the field I claimed it as a workstation. Since nobody knew it existed, and since it was way past the 3-year depreciation cycle, there weren't any objections. Unforunately CSC doesn't allow for any internal purchasing because of liability issues. So I couldn't buy it off them. I too would like to get a hold of a board. The system here at the office is the 591. That's the earlier board design. There are three different versions. I'd love to get a hold of an MCA board like this one because I have equivalent RS6000 hardware in my private collection. I could easily host such a thing. The later boards are, I believe, PCI, and in two differnt versions. I've never seen the board appear on auction sites -- and I'm worried that anyone who did have one, might not know it, since it just sits in otherwise ordinary gear. The best I can tell you is watch out for specific models of hardware and hassle the seller to see if they omitted the board. The models are the PC330 and PC500 intel systems. And in RS6000 they've used F50, 591 and a few 390 systems. >From what I've learned so far -- you won't hear much about these systems in the open systems community. If you go trolling through vendor and support organization sites, stick to the mainframe folks. I'm afraid that's as much of a brain dump as I've got on sourcing these boards. If you do find a source, please pass the information on. I'd love to add one to my collection. Until then I'll have to deal with Hercules. Not that this is a bad thing. Hercules on a decent piece of hardware is considerably faster then a P390 board. The one I've got is all of 72mHz clock speed and 128MB RAM. You could build a much more substantial LINUX based system to host a mainframe operating system.

OK, > it's not a particularly recent edition... Towers is excellent, and I'd not be without my well-thumbed copy. I suppose I should buy a newer one some day. However, it seems like every time someone in Japan or other some other parts of the Far east designs a circuit, they design or specify a new transistor for it -- a transistor that is almost identical to some existing device, but has with some minor, often trivial, tweak. I suppose it may save some corporation a fraction of a yen on each of hundreds of thousands of units. Or perhaps the way it works is that a designer says "I need a transistor with the following parameters..." and someone makes a batch to order rather than using an existing design (for which they have no stock, because of just-in-time stocking) and the made-to-order gets a unique number, more like a batch number than a type number. That's why I bought the Japanese manuals (there's one for FETs and one for diodes as well as the transistor one), and more particularly, why I posted the main operating parameters. There are probably dozens of relatively common types that could be used as substitutes for a 2SB1243. If you need one, it's just a question of looking in your favourite sales catalogue and going down the list until you see something close enough. -- Pete Peter Turnbull Network Manager University of York

ForSale/Trade: ADSL Modem & POTS line filter...

by DAW＠yalepress3.unipress.yale.edu

Help! I just moved from West Haven to Hamden, but my SNET ADSL service didn't, err, can't. SO.... I have the ADSL equipment for sale: Efficient Networks (?) SpeedStream ADSL modem, and a filter/splitter that connects at the phone block in your basement! No need for filters at each phone...

OT: FS, Metcal hot-air soldering iron

by mcguire＠neurotica.com

Uhh, what? I sell stuff on eBay all the time, and I love it dearly. I think you're thinking of someone else. I've been the [perhaps lone] person *defending* eBay through many of those flame wars. When I'm being an "outspoken critic", it's usually about "suits" and how they've ruined my industry and are working on destroying society. Or about Microsoft and their crappy products that everyone seems to think are so great. Never eBay though, because I *like* it. :-) -Dave On January 16, Ian Koller wrote: > > > > Is this going to be another one of those ridiculously > overpriced eBay items you are such a regular outspoken > critic of?

In regard to the movie TRON, as someone stated earlier, I believe the work for it was indeed done on a Cray.

There's a really nifty site about it at the following URL. http://vhost2.zfx.com/~dave/f1.html Kind regards, Sean BTW: Pete, are those EISA cards still up for grabs?

C64View PC/Mac C64 image viewer

by spectre＠stockholm.ptloma.edu

After a long, long delay, C64View, the venerable PC C64 image viewer utility, finally been updated (to version 0.5.x). A new Power Macintosh port is available as well! This version fixes a few bugs in the old 0.499.x, as well as adding support for generic 8K hires bitmaps and the ability to save the image as a .pict (Macintosh version only). C64View can thus view DOODLE!, KoalaPainter, Print Shop Screen Magic, Flexidraw, 1K colourmap and 8K bitmap files. The PC version runs on MS-DOS 5.0 or higher, as well as Windows 95/98/ME/NT. The Mac version runs on any Power Mac with CarbonLib (prefer OS 8.6 or higher). C64View is freeware.

OT? Apple Stylewriter problems (longish)

by mtapley＠swri.edu

All, I'm having and creating trouble with my Stylewriter 1. Problem appeared about a month ago. One row of pixels consistently failed to print. This happened on multiple ink-jet cartridges and after attempting to clean the cartridge (by soaking in 95% propan-2-ol, or isopropyl as the label says). So I opened the thing up, breaking only a few minor plastic latch pieces on the way (and hey, I glued them back - good as new! :-) ). I ohmed out the flex cable from the circuit board up to the print head. The left 25 pads on the circuit board end of the cable conduct with no more than a few ohms up to the 25 contacts where the print cartridge attaches. So I reassembled enough to let it print while I could still see the flex cable. Still missing a row of pixels. The left 2 of the wide traces and the right 2 of the wide traces connect to pins on the flex-cable connector which show about 3V rms while printing and zero while not printing. 3V rms means that's about what my analog Volt-Ohm-meter needle showed while printing a solid black block. But I could not get to the middle 4 connectors because the ribbon cable was in the way. So I took out the circuit board, flipped it over, reconnected all the cables (right way around? I thought so ....) and tried to print again. The printer powered up, but as it tried to print the first time, the power supply (wall-wart) quit working. This was also around the time my VM probe slipped off one of the pins on the row of transistors I was trying to check :-(. Did I short something bad, or mis-connect the ribbon cables and do something equally bad? The power supply (wall-wart) now puts out about 0.2 V (again on my analog VM), vs. the 10 or 11 it used to do. So, questions: 1) Is my (original) problem likely to be one of those transistors? There's a row of 9 of them, right next to the flex-cable connector, with big fat traces leading to doubled pins on the connector and thence to nice wide traces on the flex cable. They are labelled B1243 (I think). 2) What's a less destructive way of telling which one? - Or is it better to just replace all of them? 3) How, short of a large hammer, do I get the power supply opened up? 4) What am I likely to find toasted in there? More details available on request. I'm in digest mode, so it'll be a one-day cycle unless you email me directly (mtapley(a)swri.edu), and still probably a day because I'll read email at work and the busted machine is at home. Apologies if this is not on-topic. Thanks in advance for any help or pointers. - Mark

When I wrote this earlier in the evening, I only had the original disks. After some considerable web searching I found a reference to the P390 ftp site. The reference was not I hasten to add, to be found anywhere on IBM's support pages. The docs in the ftp site don't specifically endorse AIX5L, but it did say the system dumps I've been having were common when upgrading to 4.3.3. And I should therefore upgrade the r390 binaries I had. Low and behold there they were on an anonymous FTP server. And shockingly enough I am now sitting in front of an MVS installation that no longer system dumps all over me. Technically it still doesn't IPL, but I'm positively gleeful anyway.

The cable was near-zero resistance,in a write-head position about halfway across the page, so I don't think that's it. Also the missing line of pixels is all the way across the page, so it's not an intermittent open over the range of motion across the page. >Good luck with the glue, super glue and glue designed for polystyrene >plastics does not bond ABS plastics very well.

But Tony suggested a 1st-order test with my VOM (see below). >A dull knife hit with the same >rubber hammer on the glued seams can also work, This brick seems to have no glue. On the "wall" side (with the plug blades sticking out), it has three *deep* holes with what look like black painted metal or hard plastic beads at the bottom.

I think 8, but don't have any good evidence for that other than the row of 9 (what look like) driver transistors, of which one is slightly offset. 8 pixels would just about square with the width of the missing row vs. the distance between rows when I try to print a solid black block, but 9 might work too. The printer is 1991-93 era (about?) and was 1st generation ink-jet for Apple. I guessed 8 pixels based on the number of big wide traces coming across the ribbon cable and on the theory that it takes one big wide trace per pixel.

No number. It's a retail product that's been around for decades (Araldite was invented by Aero Research in the UK and came to fame during WW2; it was sold to Ciba after the war). We can get the numbered types as well, but they're less common; I'd need to go to an engineering (or electronics or microscopy) supplier for most of them. Unfortunately that means I can't tell you what the equivalent number version would be in the States :-( The standard stuff is a 50:50 mix, comes in blue and yellow tubes, and like all epoxies is thermoplastic. It softens at around 150 deg.C. You can vary the mix slightly to make it a little more or less rigid/hard. The normal mix sands/files well.

IBM R390 IPL woes...

by out2sea00＠yahoo.com

Folks -- Tomorrow I pick up the IBM 5362. But I have another obscure piece of hardware I'm playing with. Anyone ever hear of an IBM R390. This is an RS/6000 with an SBC mainframe in the MCA. The share IO, but nothing else. I've been rebuilding this thing as my UNIX workstation at the office. The problem I'm having is getting the mainframe to IPL (of course). This is probably, because -- fool that I am -- I FDISK'd the box and upgraded to AIX5L. Does anyone know if there's a binary compatibility issue with the mainframe board's system files, and the newer AIX binary set?

Prophylactic replacement of electrolytic capacitors?

by kapteynr＠cboe.com

Tony: You first question is answered by your second question. The reason that I propose to "insulate the computer from the world" is to solve the first problem that you pointed out: "applying the reforming voltage ... to random points in the logic" If the computer itself was "insulated from the world", the chasis would be able to float so that no actual voltage was applied to any circuit other than the capacitor being reformed. You would need to be sure that you did not even touch the computer during the process. If my theory actually works -- it could save a lot of trouble for computer restorers. My assumption is that the two sides of the capacitor are isolated from each other. This seems like a reasonable assumption to me. But, just in case, I thought I should check with those of you that might have more experience rehabilitating old computers. Perhaps I just need to find something less precious than my Altair to try it out on .... Why don't I want to unsolder the capacitors ? My experience is that I can do a lot of damage unsoldering things. My soldering skills are not as good as they were when I put the Altair together 25 years ago. My fingers and eyes do not seem to work as well as they did back then either. Perhaps I just need to get myself one of those new high-tech temperature controlled soldering irons. Tony: Reading your later messages, I notice that you recommended using a VOM meter in the Ohms mode to test the caps. I have always avoided the Ohms mode of a VOM when working with TTL circuits. The VOM applies a voltage to its test leads when it is in Ohms mode. As I understand it, delicate circuits an actually be damaged by these meters. I have not worked with hardware in years though. Maybe the modern VOM meters are safe. -Rob -----Original Message----- From: Tony Duell [SMTP:ard@p850ug1.demon.co.uk] Sent: Monday, January 14, 2002 6:09 PM To: classiccmp(a)classiccmp.org Subject: Re: Prophylactic replacement of electrolytic capacitors? > > I have not yet tried this yet -- > In theory, electrolytics can be re-formed. > There is a very thin aluminum oxide layer that disappears after a long time. > Running current through the cap will rebuild the insulating layer > until current will no longer go through it.

It'll do a lot less damage than applying the reforming voltage (a little above the working voltage of the cap) to random points in the logic. For example, there are likely to be some 16V electrolytics between the +5V line and ground. Do you seriously want to try running TTL at 18V?

Nope, original Araldite (sets in about an hour and cures fully in 8-24 hours, faster at higher temperatures) and Araldite Rapid (sets in 5-10 minutes, and cures in about an hour) are both clear-to-amber epoxy resins. Both are mixed 50:50; both come as light amber resin and transparent bluish hardener. The company does make other products, including Aerolite, and some other epoxies, perhaps what you've seen is one of those. -- Pete Peter Turnbull Network Manager University of York

Prophylactic replacement of electrolytic capacitors?

by pete＠dunnington.u-net.com

On Jan 14, 10:01, John Allain wrote: > > The best way to check those #$%#$%^# caps is to use an ESR meter. And > > only then should yo buckshot them.

The quick and dirty test is to use an *analogue* meter (what Americans used to call a VOM, not a VTVM) on the ohms range across the capacitor. The needle should flick violently across (indicating zero or low resistance) and then fall quickly (at first) as the capacitor charges (and the current drops). Ideally it should end up showing virtually infinite resistance. It needs a bit of experience, though, as the violence of the flick depends on ESR and capacitance, and there tends to be some leakage in an electrolytic so the final reading is often not zero current. It may be worth trying if you have a known-good capacitor of similar voltage and capacitance to compare. A digital multimeter is rarely any use for this, though. The response of the meter is just too slow; by the time it's shown the first reading the event is all but over. Also most DMMs use very low voltages and currents, not enough to give a big electrolytic a good fright. -- Pete Peter Turnbull Network Manager University of York

I've heard the following, to add to that list: Pentium/Pentium II -- PowerPC Pentium III -- PowerPC G3 Pentium IV -- PowerPC G4 FWIW I'd bet a buck there's a LOT of disagreement on the list. Unfortunately, there's just no adequate way to compare the full range of recent and current mprocessors by looking for strict equivalencies. It would be interesting to see a chart covering the relative relationships of processors in PeeCees, Macs, and Minis (including Sun, SGI, RS/6000, etc.). I had to chuckle at the poor dood who was lamenting his $10K investment in a IIcx; most of us cry to think about what we paid for our old Morrow or original IBM PC.

You're right; the 68010 saves slightly more state on the stack than the early 68000. I have a feeling that was fixed in later 68000; some traps save more state than others.

Zebra system

by mythtech＠Mac.com

in case anyone cared (who knows with this group sometimes) The Zebra computers I had that ran Pick were "Zebra 2500" made by General Automation. Now that I am back in my office, I just looked at the manuals under my desk. If anyone wants them, the manuals are available (I don't really want them for anything). Best offer takes them, minimum offer of cost of shipping (from Ridgewood, NJ 07450, or you can pick them up). There are two 3" binders with assorted smaller manuals clipped into them. Most of the manuals seem to be about Pick more than about the Zebra machines. If anyone wants a list of what the smaller manuals are, let me know and I can flip thru and write down the names. -chris <http://www.mythtech.net>

Available: Commodore 64 with drive

by mythtech＠Mac.com

I have a C-64 here with a floppy drive. No cables of any kind (but I have a call into the guy that gave it to me, to see if he still has the cables). Anyone want it? I don't know it if works, but my friend said it worked when he stopped using it (5+ years ago). It is rather dusty, and was kicking around on his basement floor when I found it and asked if he still wanted it, so who knows the condition now. I don't know the value of such a machine, nor do I think I care... I just want to get rid of it (taking old electronics is an addiction of mine that I need to break since I ran out of room a long time ago). There is a copy of Bank Street Writer sitting in the disk drive. The drive is a 5.25 drive, model number 1541. The stuff is available as a package, or in peices. Best offer gets it (or any part of it), with lowest acceptable offer being cost of shipping (shipping out of Ridgewood, NJ 07450, you can also pick it up if you want). If I can get the power supply and disk drive cable, I will post a note. So to sum up... items available: C-64 5.25 floppy drive model 1541 5.25 original disk for Bank Street Writer -chris <http://www.mythtech.net>

A story

by tarsi＠binhost.com

Hi, folks. A story for you. A long time ago and not so far away, a small town church obtained it's first computer. An IBM PS/2, quite sophisticated for the day. It was in the secretary's office for use of keeping budget and some word processing. As luck would have it, a young boy was around when his father was working on the computer. He must have been around 12 or 13. His father got to work on the computer because he was treasurer. The boy was jealous, a toy! A toy with lights and whirring sounds and computer sophistication, similar to the Apple computers that he had known so well from school. The boy wanted to touch the computer, but knew better. Sort of. The boy touched it once when his father was away and the office was open. He started up the fancy computer and looked as it powered up. He was very impressed. He looked through the manuals. He tried to run some software. He marveled at this wonder of technology. Fast forward to 2002. The same boy and a friend of his had gone to a town quite far from the church to have some Chinese food and catch up with each others' lives. Now being grown up, the boy still had a great liking for old computer toys and things. Being bored, the two friends went to the local Goodwill to look around and see what there was. Back in the corner on a table was a small computer system, quite old. It didn't have much with it, just the computer, a monitor, and a keyboard. However, the boy didn't have this type of computer in his collection yet, so he went to the local ATM and got some cash, came back, and bought the computer. Bring this computer home, it sat in the corner for some time, preempted by some other computer hardware, for the boy had a large collection. One night, being quite productive, the boy decided to boot up this $10 computer and see what was on it. The boy knew very little of what he would find hidden in the secrets of the hard drive of this computer. For the new, fancy computer that the church had purchased and the little boy had marveled over so long ago had served its time, and had been replaced. It went to a number of other people, the files left on its hard drive a testament to the movement of the computer. And eventually, the computer came to be donated to a Goodwill and put up for sale. The boy, Nathan Pralle, found that the computer he had admired so long ago was sitting before him. Indeed, the very first PC he had ever touched, the one at Trinity Lutheran Church in Hampton, IA, and one which had contributed to his becoming a computer programmer, was now sitting on the floor of his very living room, about to become part of his computer collection. An IBM PS/2 Model 30. And now you know the rest of the story.

DECvoice boards for trade

by rdd＠rddavis.org

Greetings, Since I have no access to a T1 telephone line, and hence am unable to use the DECvoice board set in my VAX 4000, consisting of one each of M3135-01, M3135-02 and M3136 boards, I was wondering if anyone's interested in a trade. The bulkhead panel, and cabling to these boards that came with my VAX, will be included. The DECvoice software appears to reside on my system we well. It appears that resellers are asking quite a bit (over US$1,000) for one of these boards. If anyone's interested in making an offer for the set, or individual boards, of cash or trade, then I'm willing to consider offers for trade. Some of the things I'm interested in and may consider towards a trade: - additional memory - large DSSI disks with sleds and front panels - SCSI board - a tape drive and mounting sled/brackets, etc. (preferably DLT) - hub with both BNC and and 10-Base-T connectors Other suggestions are welcome. :-) -- Copyright (C) 2001 R.

It was also supposed to have a color screen. That said, I suppose it wouldn't be difficult to run the drive interface cable through a plate in the back of the machine, if you can find a plate that will fit it, and has a hole for a connector that you can run to an external drive chassis. In fact, I haven't opened the machine in ages, but you could possibly even run the external disk as a second drive, given some other slight modifications. I don't recall whether the UnixPC had any data cable header for a second drive. Probably not, since it wouldn't have fit inside. On the other hand, there are MFM to SCSI bridges, I believe, and I wonder whether you could just use one of those and run some 1GB or so disk on it.

Mac IIci

by fernande＠internet1.net

Hello, The Local GoodWill has a fairly nice Mac IIci. I've done some research on the Low End Mac web site, but am still undecided if I should buy it. Low End Mac says it is a "Mac Best Buy", meaning that it is one of the models to buy, instead of avoid. Some models are best avoided because of compromises in design or limited expandability. It is uses a 25mhz Motorola 68030 processor. What would be the approximate Intel/PC equivalent? The 386DX-25? The 486DX-25? faster, slower, what? I don't have much Mac experience at all. I own a Plus, but after cleaning it, I haven't done anything with it but let it sit, mainly because of the silly 800K drives. It has a Radius video card, but unfortunately, the Radius monitor got sold separately. It was a "Pivot" monitor. I pulled the monitor of the nonfunctioning IIcx and the ci boots fine, and is running System 7.1. How much should I offer? Thanks, Chad Fernandez Michigan, USA

Prophylactic replacement of electrolytic capacitors?

by kapteynr＠cboe.com

I have not yet tried this yet -- In theory, electrolytics can be re-formed. There is a very thin aluminum oxide layer that disappears after a long time. Running current through the cap will rebuild the insulating layer until current will no longer go through it. I want to reform the original capacitors in my Altair "in place" -- i.e., without unsoldering them. I have the following setup in mind: 1. Insulate the computer from the world -- unplug it and put it on a rubber table. 2. Use ultra mini test clips to connect to both leads of a capacitor. 3. Connect the test leads to one of those lab power supplies that have adjustable DC voltage and a milli-ammeter. 4. Connect + on the lab power supply to + on the capacitor (very important). 5. Start at zero voltage and increase slowly while looking at the ammeter. 6. Stop increasing the voltage when the ammeter reads anything more than a few milliamps. (If it draws too much current, the capacitor will heat up and may blow up) 7. Wait for the current on the ammeter to drop to zero. 8. Continue to increase the voltage, and wait for the ammeter to drop until you reach the rated voltage limit of the capacitor. 9. Repeat for every electrolytic cap in the computer. Has anyone done this ? Will it work ? Comments? -Rob

RAM request

by jhellige＠earthlink.net

Well today I got my NeXT Dimension board fully functional with 32MB of RAM installed. Unfortunately the RAM came out of my slab. I am asking this here due to the number of SIMMs I am now in need of. If anyone has the following and would like to sell them, please let me know. 16 - 4MB 30pin SIMMs, 100ns or better, parity or non-parity (as long as they all match), low profile preferred. These are to replace the 1MB SIMMs currently in my Cube's '040 mainboard. 8 - 4MB 72pin SIMMs, 80ns or better, 1M x 32 or 1M x 36 (as long as they all match). These are for my slab to replace the SIMMs I pulled for use in the Dimension board.

There are two relevant differences. The first is that on the 68000 (and 68008), reading the system byte in the status register isn't privileged, so MOVESR works in user mode as well as supervisor mode. In the 68010, that was corrected and an extra opcode was added to allow reading the user byte (condition codes) in user mode. The second difference is that the 68010 has the VBR (vector base register) so different interrupt/trap vectors can be used in different modes; the vector base is fixed in the 68000/68008. There's no difference in things like address range, modes, MMU interfacing, etc. Those changes came with the 68020. The other changes were improvement to the microcode, which made loops faster. -- Pete Peter Turnbull Network Manager University of York

Umm, no, that was the 3B1. It was most definitely released, as I've had several of them. I used to run Seagate ST4096 80MB drives in them. I'd kill for one with a color display though. :) > On the other hand, there are MFM to SCSI bridges, I believe, and I wonder whether you could just use one of those and run some 1GB or so disk on it.

Repeat for every electrolytic cap in the computer. > > Has anyone done this ? > Will it work ? I've not done that in-circuit, but it might work. There are some gotchas. If you're talking about power smoothing caps, any voltage you put on the cap will also be powering the rest of the circuit. Disconnect any transformer. You don't want to feed them DC. Also, the current drawn by the rest of the circuit will make it impossible to gauge the leakage current in the capacitor. If you're talking about any other capacitor, putting a voltage on it may provide power to some signal line connected to an unpowered device, which the device may not like. In particular, TTL doesn't like power on some signal inputs when there is a ground connection but no Vcc. In either case, the voltage rating on the capacitor is likely higher than the maximum for the logic ICs, and TTL in particular does not like excessive voltage (NMOS is more tolerant). Don't exceed the lowest maximum-voltage rating of any device on the board. Of course, you're assuming that the capacitors need reformed. They might not (but it's good practice to assume they might). If you can't remove them without risking damage to the PCB, I would try feeding power into the board through a current-limited supply at a low voltage and gradually winding it up to the normal value over a period of several tens of minutes. If they've completely dried out, they're dead anyway. Stop if the current shoots up, or seems too high -- you probably have a short. Is an Altair board like a typical S100 board, fed from an 8VDC unregulated supply, and with on-board regulator? If so, just use a bench supply as above. -- Pete Peter Turnbull Network Manager University of York

VAX 11/780s - Masscomp - Valid equipment available

by kapteynr＠cboe.com

Finally -- a nice haul in my area. BUT I WAS ON VACATION !!!! Is any of this still available ? It ALL looks interesting to me. I am in Chicago and I have a truck, and a lot of storage space (with loading dock). -Rob -----Original Message----- From: Jon Auringer [SMTP:auringer@tds.net] Sent: Tuesday, January 08, 2002 6:53 AM To: Classic Computer Mailing List Subject: VAX 11/780s - Masscomp - Valid equipment available Hello all, Along with the Astronautics ZS-1 machines I posted about earlier, we have some other equipment available. I have someone interested in one of the 11/780 machines and possible others. As with the ZS-1 machines, the time frame isn't very long. Again, we are closing this facility and the equipment will be scrapped if not rescued. 1 DEC 11/780 (3 wide cabinet) currently up and running 4.2 BSD 3rd cabinet has a Ven-tel plugin modem rack w/~10 modems 1 rack containing 4 Fujitsu Eagle drives (one drive is off-line due to increasing errors) 1 Fujitsu 9-track tape drive in 2 wide cabinet (not quite as tall as the VAX cabinet)(This is a nice auto loading drive, there is a second one available with two drives from a non-VAX system) 1 DEC TE16 9-track tape drive (1 wide cabinet) 1 Fujitsu line printer 1 DECWRITER III printing terminal as console 1 DEC 11/780 (3 wide cabinet) currently down but was running fine when turned off (VMS) 3 DEC RP07 drives (each the size of a washing machine on steroids!) 1 DEC TU78 9-track tape drive 1 Scicards design station (This is a dedicated color graphics terminal used for printed circuit board (PCB) layout) I am told the tube was a little on the fuzzy side. 1 Benson photo plotter (we used this exclusively to print out PCB artwork for checking) 1 Dataproducts line printer 1 DECWRITER III printing terminal as console 3 Valid Systems m68k based Multibus systems. Each system has several dedicated mono graphics cards to drive multiple design stations. Each system is in a half-height rack which contains the Multibus rack, an 8" Fujitsu fixed disk drive and the slot loading 9-track tape drive. I am unsure of the status of these systems. I believe they were running when shut down, but I have doubts about the drives. 6 or more of the Valid Scaldstation design stations. Each includes a table with built-in digitizer and a 19" green monochrome graphics monitor. These systems were used primarily for schematic capture, but ran a full blown UNIX, so I always enjoyed reading news on the "big screen". :) 1 Masscomp m68k based system This system is also Multibus based and resides in a pair of 5' high racks. One rack contains the multibus chassis and a pair of Fujitsu drives. The second rack houses the 9-track tape drive and a third 8" Fujitsu drive. This machine was only lightly used when I signed on in 1989, and shut down shortly thereafter. I have gotten it up and running RTU on its ST-506 boot drive, but haven't managed to get the Fujitsus online. 7 Masscomp MC-500 deskside chassis These are also Multibus based m68k systems. These run the same OS as systems above. They have an internal 5-1/4" floppy and ST-506 fixed drive. There are a bunch of the monochrome graphics tubes that go along with these units. Actually, it appears like each chassis is designed to drive a pair of the graphics terminals. I have one of these boxes that I did a clean install of the RTU OS. The other 6 are in varying states of repair. I think there are enough bits to assemble at least 3 more complete systems. 2 DEC MicroVax II in a 19" There is also a rack mounted chassis with a pair of SMD drives. Each of the MVII has a SMD controller card. Both of the boot drives are dead and I don't have a way to format replacements. I would like to hang on to these if I can manage to get them home without doing myself harm. 1 Tek 4014-1 graphics terminal w/hard copy unit. The terminal works fine, but I haven't had a chance to test the hard copy unit. I would like to hang on to this unit, but moving it is definately a two person and a truck kind of thing. So I may have to let it go. :( ? StorageTek 9-Track drives. 110V operation. How many of these I have depends on the fate of the ZS-1 machines. I have a couple now, and will have several more if the ZS machines are scrapped. Large quantities of documentation. Over a dozen UNIX programmers manuals in metal desktop racks. Complete documentation sets for VMS, gray and orange binders. I have a box with complete unopened docs for a later version (don't remember off-hand which version) of VMS than we had ever installed. Documentation for several revisions of SunOS4. If I were to walk through the building, I could easily double this list. Basically we have just about everything!
