Not too long ago we were looking for a replacement for our RS/6000 models 320 and 375. The only RS/6000 of a sesible size and price with comparable floating point performance was the model 397. Why? It still used a Power2SC processor. All the more modern ones use PPC and it slows, er, shows! (we bought Sun in the end. With luck I'll get the 375 or both 320s. I don't think I'll get all 3 machines :-( ) Philip

Starting an intact 3/60 is not that complicated. I'm essentially building one from scratch. -ethan _________________________________________________________ Do You Yahoo!?

chips

by edick＠idcomm.com

There have, in recent years come to be other manufacturers offering the PALCE version of the popular LATTICE GAL's. Cypress is, indeed, among them. As for the feedback, if you use pins 1 or 11 as something other than CLOCK or /OE, as they were used in the 16-series PALs, then the input path from them preempted the feedback from these end macrocells. I wouldn't remember that, except that PALASM slapped my wrist for it a couple of times early in my experience with them, so, like the dog who once pee'd on the electric fence, I remember that. There are other little "gotchas" with the various versions of these parts.

I worked for a "third-party vendor" back in those days. We were denied a license in 1984 when we first applied (when it would have done some good) and were granted one in 1989, long after the VAX-BI was relevant. We sold a handful of boards, only part of our prototype batch (compared with hundreds of Q-bus boards and a couple thousand UNIBUS boards). Because DEC never really opened up the licensing program until later (unless you made a board that they didn't care about, then it was easy), the market never really took off for them. Once the VAX-4000 line came out, it was easier and cheaper to buy a couple of 4000's to replace aging 11/7xx and other mid-range VAXen than it was to jump up to a 6xxx or 8700/88xx. We had more UNIBUS->Q-bus upgrade sales than anything->VAXBI. I still have most of that first run of board. If I ever have far too much time on my hands, I'll write some new code for it - 68010 @ 10Mhz, Z8530 SIO, 2Mb RAM, 64kb ROM, DMA interface, timer. I suppose I could turn it into an intellegent PPP interface or make it do Localtalk (with a change in line drivers) -ethan _________________________________________________________ Do You Yahoo!?

VCF Announcement

by dastar＠ncal.verio.com

Note: some of the links referenced are broken at present...under construction and all that. Parallax Inc. and Dr. Dobb's Journal proudly present... The Vintage Computer Festival 3.0 October 2nd & 3rd Santa Clara Convention Center Santa Clara, California www.vintage.org For the third year in a row, the Vintage Computer Festival is back to thrill and amaze you with the history of one of the greatest inventions in all of mankind, the computer! This year: * More great speakers! * More great exhibits! * More great vendors with Cool Stuff to sell! * More fun games and contests, including the Nerd Trivia Challenge! * Tour The Computer Museum History Center! * And of course, FREE STUFF!! In short, plenty of stuff to indulge all your SENSES: HEAR the speakers! SEE vintage computers! TOUCH them too! SMELL their electronics! But please don't TASTE them! "The mission of the Vintage Computer Festival is to promote the preservation of 'obsolete' computers by allowing attendees to experience the people, stories and technologies that embody the remarkable tale of the computer revolution." Register Early and $AVE! Register by June 30 and pay only $15 per person (or $20 per person by September 15). That includes access to the entire event all weekend, including the speakers, the exhibit and the flea market. Kids 17 and under are admitted free, and as always, parking is free too! To pre-register, send a check or money order to: Vintage Computer Festival 4275 Rosewood Drive #29-161 Pleasanton, California 94588 Or visit the VCF website for more information and a handy registration form ready to print (http://www.vintage.org/vcf/register.htm). The Speakers Horst Zuse Horst, the eldest son of early digital computer pioneer Konrad Zuse, will be giving a lecture on his late father's machines and will focus on the computer businesses that Konrad later founded to market his ideas. Jon Titus Who can forget one of the earliest of kit microcomputers, the Mark-8? Jon designed the Mark-8 around Intel's 8008 microprocessor and wrote a construction article which appeared in the July 1974 issue of Radio Electronics. Todd Fischer Todd bought the assets of IMSAI after their bankruptcy and continued to manufacture and sell IMSAI products under the Fischer-Frietas Corporation. Todd consulted with MGM for the movie _War Games_ and, as a treat, will be bringing along for show and tell the actual IMSAI 8080 computer that co-starred in the film. Stan Veit Stan is an early chronicler of the microcomputer revolution, and also a participant. Stan started one of America's first computer stores in New York, and in the process forged relationships with some of today's revered pioneers, including Steve Jobs and Steve Wozniak, whom he shared a booth with at the first West Coast Computer Faire where the Apple ][ was debuted to the world. Jim Willing Our admired and beloved VCF Celebrity, Jim will wax philosophic on various themes of stupendous relevance. Eugene Kim Eugene is a writer for Dr. Dobb's Journal (a VCF sponsor!) and will be giving a lecture on the history of free software, a very relevant topic considering the free-software movement is in full force in today's computing arena as evidenced by the escalating adoption of GNU/Linux. Curt Vendel Curt is the founder of the Atari Historical Society (check out his great website at http://www.atari-history.com) and has amassed an amazing collection of Atari artifacts and company history, including some one-of-a-kind Atari prototypes. Curt will be bringing along some of these prototypes for show and tell. Roger Sinasohn Roger is an avid collector of early portable computers and will be giving a talk on the history of the Kyocera 85, a.k.a. the Tandy Model 100, a.k.a. the Olivetti M10, a.k.a. the NEC PC-8201A. Doug Salot Doug's research has uncovered what he believes to be the first "personal computer". Forget the Apple ][, the Altair or even the Alto. Doug's pick as first PC goes all the way back to the 1950's. Designed by Edmund Berkeley, an unsung hero of computer history, Doug intends to win Berkeley the prominance and praise that he feels is much deserved by this virtually unknown computer visionary. Plus! Workshops by Parallax on their amazing little BASIC Stamp. Get a preview of this cool little device by visiting their website at http://www.parallaxinc.com. More speakers to be announced soon! Check the VCF website for updates. The Vintage Computer Faire and Exhibition This year, the Vintage Computer Festival exhibit will feature the exhibits of individual collectors, all vying to win first, second or third place in eleven categories, plus the coveted "Best of Show" award.

SInce these are electrically eraseable it's of no consequence what the previous program was. These parts can be viewed as a relplacement for the entire 16xN series where x=L or R and N ranges from 4 to 8. They can effectively emulate/replace 16L8, 16R4, 16R6 and 16R8 with a few exceptions. The macrocells associated with pins 19 and 12 have no feedback path of their own, i.e. it must be via the adjacent macrocell.

chips

by edick＠idcomm.com

These parts aren't PAL chips FOR a specific application. They're about 10-year-old electrically eraseable and reprogrammable GAL (generic arraly logic) parts, intended to become lower-cost replacements for the bipolar PALs. In the latter purpose they have been quite successful, in that I seldom even see a bipolar part in boards less than 15 years old. The advantage, of course, is that these have a more flexible architecture and variable macrocell design than the original PALs, say, from MMI, had. Of course there are only a few of them that are asynchronous, and those, typically, are just copies of the 20RA10 in more current technology.

British Science Museum needs a lesson in history

by dastar＠ncal.verio.com

Here's an interesting announcement from the British Science Museum that might interest some of the folks in the UK (Tony, now you can get a job!) OPERATE THE BABY COMPUTER Would you like to work on the rebuilt 'Baby' computer? This rebuild of the original which ran for the first time on 21 June 1948 is on display in the Futures gallery at the Museum of Science and Industry in Manchester. The Museum needs help to keep the computer in working order and to demonstrate it to visitors. You should have some experience in and knowledge of electronics. An interest in the history of computing would be desirable. You should also be available once during the week for training and, if possible, at the weekends for demonstrations. You will join the Museum's volunteer programme and will receive training on the computer's operation and maintenance, on its background history and on talking about the computer to Museum visitors. The Museum is the only place where you can have this opportunity to work with the first computer. You will be able to learn from the people who rebuilt the computer and benefit from the experience of explaining it to visitors. If you are interested in helping, please contact Jenny Wetton at the Museum, telephone 0161-832-2244, or email: j.wetton(a)msim.org.uk --- What's funny is the state in the second to last paragraph: "The Museum is the only place where you can have this opportunity to work with the first computer." Konrad Zuse might have a problem with this.

I'd better pay a bit more attention when I'm glancing through the subject lines... > It was open for a minimal definition of the word open. > DEC owned the chip set and protocol and would sell you the chip set > if your board was not a competitor to a DEC board. I can vouch for this. The company I used to work for did a couple of VAXBI interface boards: a quad IEEE-488 board and an interface to a custom shared memory. DEC had to be convinced where product was complementary before it gave you the right to buy chips. > A number of outfits purchased the older lowest priced DEC board > available to pull the chips for the BI bus to make disk controllers > and such since DEC wasn't going to let anyone reverse engineer the set > without a major patent fight. There was a memory company that reverse engineered the BI bus, at least enough to build memory cards. Clearpoint, perhaps? I don't recall which. IIRC, they were bought by an I/O company (Emulex, maybe?) primarily to gain access to their reverse-engineered BI chip. > DEC cut it's own throat on this one and the BI bus never took hold. There's also the fact that for the average bus transaction it really wasn't any faster than the UNIBUS. You had to _always_ do octaword transactions to outperform the UNIBUS (at least, the theoretical max of the UNIBUS; and by the time the VAXBI appeared, it was starting to be possible to get the theoretical max out of the UNIBUS. I once did a processor module that did the UNIBUS mapping during the settle(?) (the one that was after the deskew time) time; once that 75ns was up, the processor module knew that the adders had had enough time to map the address and didn't need to add any extra delay for the mapping. The processor module could support a J-11 running full bore while simultaneously outperforming the PDP-11/84 on DMA throughput. And it looked enough like a PDP-11/84 to run RSX-11 out of the box). > who left DEC around the time of the BI bus release... and has NO > proprietary data on 'em. I've still got a couple of copies of the VAXBI manual. Roger Ivie ivie(a)cc.usu.edu

PC's Limited (1986 on topic)

by jeff.kaneko＠juno.com

Actually, my understanding was that at least one of the 1st PC's limited machines were unique: 386PC's design using multiple megabytes of *static* memory to keep up with the *blazing* 386-16 then in use.

Heads up: Vax 3400 for disposal

by Philip.Belben＠powertech.co.uk

Greetings everyone on both lists: I have a lead on a microvax near Birmingham, UK. All items in good, working condition unless marked "not checked". I am interested in people's comments, but the person to make offers, answer queries, etc. is Martin Poole, martin.poole(a)pgen.com Closing date for tenders Noon (British Summer Time) 12 July 1999. System: Microvax 3300/3400 Computer System 32Mb MOS memory, 3*381Mb DSSI ISE, Std Kbd., Mono Term. Expansion Cab, ?" Cartridge Tape Drive Spare Microvax 3400 Computer System (backup m/c.) (Not checked) Printers and peripherals:- LA324 -AE 24 pin Dot Matrix Printer (Three off) LA210 -A3 Letterprinter (Three off) Oki Microline 393C 24 pin Dot Matrix Printer (Three off, of which two not checked) Assorted tapes and ribbons for above The machines are now decommissioned but were in continuous use from new in 1989 till April 1999. They have always been supported by a maintenance contract, originally with Digital but in recent years a company called ICM Team had the contract. There are three cabinets, all desk-side size (28" tall x 14" wide x 20" deep) being (I think) the main CPU, the backup CPU and the expansion box. Since I (still!) haven't signed the lease on a storage unit of my own (local council not replying to letters), I shall probably not be bidding, but what do people know about these machines? How fast / reliable / compatible / easy to set up are they? Good luck, one and all. Philip.

ZX81

by peter＠joules.enterprise-plc.com

I think I may hve missed out on a bargain yesterday. I was walking around Surbiton, yesterday and in one of the charity shops they had a ZX81 complete with original manuals and a black and white TV for 15UKP. I left it there becuse I could not have carried the TV all the way to the car about a mile away. Perhaps I should have told them that I would give them 15 quid for the computer and they could have the TV. If any of our UK members are nera Surbiton and would like to see if it still there then the shop is and educationaal charity, I can't remember the name. It is about opposite Sainsbury's and is the second charity on the left hand side of the road if walking up from the traffic lights towards Surbiton railway stastion. Regards Pete

Available: IMSAI Chassis

by jimw＠agora.rdrop.com

For Sale/Trade/Whatever... IMSAI 8080 chassis and CPU board. Why 'chassis' rather than 'computer'? It's missing the front panel. I had been considering rebuilding it into a replica of an IMSAI dual-floppy sub-system, but it looks like I may have finally tracked one of those down, so now this piece is (somewhat) surplus. It does have the power supply and full card cage, so there is potential. Mayhaps someone has one of the third party 'smart' front panel boards that they want to play with? Any which way... I'm entertaining offers, lest I decide that I really need the room (and $$) and offer it up to the vultures on ePay...

Local bus schedule

by edick＠idcomm.com

At the time BI came out we (I then was working for a military/aerospace contractor) were developing a portable military workstation based on a microvax-II. We briefly considered building our own version on the VME bus as opposed to Q-bus, when we learned that the BI-bus interface chipset was the microVax processor set. This would have saved lots of dough and let us use current generation hardware in place of the obsolete rubbish for which DEC charged so much dough. Politics doomed that notion, however. The KIM didn't have a way to float the processor's address bus, nor did it support prioritized interrupts, both of which were a little-used "big-deal" on the S-100. The fact that it also didn't support I/O instructions was a real limitation, though.

Unfortunately, the KIM didn't produce the appropriate signals for about half the functions on the S-100. (Neither did many of the CPU's offered for the S-100) This stood in the way of a successful commercial product along these lines.

Why does my Apple IIe run so _fast_ ?

by guerney＠uq.net.au

I have just played with an Apple IIe (Model A2S2128X) I was given. It is obviously "souped up" as everything runs so _fast_. Most games are impossible to play on it. I just tried a pinball simulation and the ball just bounces around at 100mph! I ran a BASIC graphics extension demo and the bits which were supposed to show "slow" drawing to the screen were real fast, and the "fast" draw was instantaneous. It is not hard to guess that a chip called the "ZIP CHIP Model 8000" plugged into the lower left of the motherboard has something to do with it! I came into microcomputers through the Commodore line, and have never known much about Apples, and I have not accumulated enough reference material to find something about this add-on. Another thing with this unit is that it happily runs DOS 3.3 but any ProDos disks are greeted with a "UNABLE TO LOAD PRODOS" banner. So it will not run Apple Works etc. There is also a PlusRAM II 1MB RAMCARD which is fully populated with 1MB RAM. I suspect that card must have cost $$$ in its day. What do I need to access this memory?Another slot holds a tiny card called a Berkely Softworks IRQ Manager. The centre slot contains a AIIE 80col/64K Memory Expansion card. The remaining slots are the more common Disk II Interface, Mouse Interface and "AII Parallel Interface" cards. Anything anyone can tell me about what makes this IIe run like it does?

VME (68K and old, large SPARC servers used this) Multibus (favored of Intel, found in older Cisco products and the NCR Tower) Microchannel Zorro II/III (16/32-bit Bus used in Amigas) OMNIBUS (PDP-8/e/f/m/a - lots of batches of 12-bit signals) C-64 expansion bus \ VIC-20 expansion bus - 6502 signals and memory decode stuff, like the Apple ][ PET expansion bus / I guess it just depends on how you are using the term "local bus". If you mean direct access to processor signals, these should all count. Some of these appear as a local bus in some machines (BI bus in the 8200, etc.), and a peripheral bus in others (BI bus in 85xx/87xx/88xx/6xxx...) Same goes for the UNIBUS (main bus in older PDP-11's (11/20, 11/05...) but one of several busses in later models (11/70, 11/84, etc.) -ethan _________________________________________________________ Do You Yahoo!?

VCF Announcement: Nerd Trivia Challenge

by dastar＠ncal.verio.com

Nerd Trivia Challenge Official Rules and Regulations http://www.vintage.org/vcf/ntc.htm 0. The Nerd Trivia Challenge is a game-show like event geared towards the computer history enthusiast. Questions concering computers, their inventors, their technologies, and their software are relevant. The questions are carefully selected by a panel of amateur computer historians and are researched as thoroughly as possible to ensure the correct answer is associated with each question. Only questions with unambiguous, undisputed answers are used in the game. 1. To be considered as a player you must first pass a pre-qualifying quiz given when you arrive and register at the VCF. This is a series of 10 free-form answer questions, with each question being worth a point. The pre-qualifying quiz will be given on days one and two of the VCF (Saturday, October 2 and Sunday, October 3). The top ten scores will then qualify to move on to the final qualification quiz. 2. If you qualify then you must be available on day two of the event (Sunday, October 3) at 2:00pm to take the qualifying quiz. This quiz consists of a series of ten questions, each worth a point. The top three scorers on the qualifying quiz will be chosen to play the Nerd Trivia Challenge. In the case of a tie, a tie-breaking question will be asked in a "sudden death" format. The first person to respond with the correct answer to the tie-breaking question will be chosen as the final player. 3. The contest consists of two rounds with 25 questions each round in five different categories (five questions per category), plus a final round consisting of one question. Each question in each category is progressively more challenging than the last. 4. Scoring is in "bits". In round 1, the questions at the top of each category are worth 5 bits and increment by 5 bits so that the last question is worth 25 bits. In round 2, the questions start at 10 bits each and increment by 10 bits so that the last question is worth 50 bits. Scores will be displayed in the Octal numbering system. 5. Before the game begins, a player will be selected at random by a computer to be the first to choose a question from the game board. 6. The game is played thusly: each player's score starts at 0 bits (or NULL). The game is controlled by the Master Nerd. Each player has a hand signalling switch. The player who was chosen to go first will pick a question from the game board. The question will then be read by the Master Nerd. Once the question has been read, the player who signals quickest will be called upon to answer the question. 7. The player who is in control of the board may pick any question of any category they desire. There is no requirement to pick the questions in order, and there is no requirement to stay with a category until all its questions are exhausted. In other words, the questions may be picked in any order the contesant who is in control of the board desires. 8. A question may not be answered until the Master Nerd has read the question in its entirety. Once the question has been read, a player must signal within 3 seconds to answer the question. If no player signals before the 3 seconds have elapsed then the question is withdrawn, and the correct answer will be read. 9. The player signalling has 5 seconds to produce the correct answer. If the time elapses before the player successfully answers the question then the question is considered answered incorrectly by that player and the question is then re-opened to the remaining players. 10. If the question is answered correctly the bit value of the question will be added to the player's score. An incorrect answer will result in the bit value of the question being deducted from the player's score. The question is then re-opened to the remaining players, with the same time constraints as outlined in 8 and 9. 11. Round one includes a special Nerd question, and round two includes two special Super Nerd questions, which are found only upon a player selecting the question where these special questions are hidden. When a player selects a Nerd or Super Nerd question, they will be allowed to wager any amount (greater than 0) that they will produce the correct answer to the question. In other words, the player will be able to determine the point value of the question. The amount wagered may be up to the player's score, or the value of the question, whichever is greater. If the question is answered correctly, the bits wagered will be added to the player's score. If the question is not answered correctly, the bits wagered will be deducted from the player's score. In such a case, the question will not be opened up to the other players. 12. There is no time limit on rounds one and two. The rounds will continue until all questions on the board have been selected. 13. The final round consists of one question which all three players will have the opportunity to answer. The players will first be told the category of the question. The players must then secretly record a wager that they will produce the correct answer. The wager can be any amount from 0 bits to their current total score. Once the players have recorded their wagers, the final question will be read. The players then have 30 seconds to secretly record their answer. Once the 30 seconds have elapsed, each player will be asked to reveal the answer they recorded. The players producing the correct answer will have the amount they wagered added to their score, while those producing an incorrect answer will have the amount they wagered deducted from their score. 14. The player that has the highest number of bits at the end of the game is declared the First Place Winner. The players with the second and third highest scores are considered the Second and Third Place Winners respectively. In the case of a tie between any players, a tie breaking question will be asked. The first contestant to successfully answer the tie-breaking question will be awarded the place they are competing for (i.e. First or Second). The process will be repeated in the event of a three-way tie. 15. Any questions or comments concerning these rules or the Nerd Trivia Challenge in general may be directed to ntc(a)vintage.org.

New Finds Today

by museum＠techniche.com

Stopped at the local surplus store today and found a double wide 7' tall HP rack full of old equipment. Out of it I pulled an HP 21mx, HP 9-track tape drive, HP pizza oven disk drive with a removeable pack installed and finally an HP Paper Tape reader. These were all still hooked up so I also picked up the connecting cables and the equipment slides. I left the rack since I have an empty one empty and waiting and it's alot cleaner then the one I took these out of. Cost -- $50. and a couple of hours time to disassemble and move it all (the disk drive is incredibly heavy). I had to put this all into storage immediately because I'm leaving on business so I didn't have time to note peripheral model numbers or inventory the cards in the CPU (however every I/O slot on the back was populated. On another topic, can anyone tell me exactly what the Morrow ADM-20 was? I have a lead on one, I understand that it is a CP/M machine. Is this one of the S-100 boxes?

Founder of Sphere surfaces

by dastar＠ncal.verio.com

Michael Wise, the founder of Sphere, has surfaced. His website is at http://www.users.uswest.net/~mwise/index.html. He's another one claiming title to inventor of the "Personal Computer", plus claims of other "firsts" that you can find on his website. I'm sure there will be plenty of debate. I'm trying to get him to speak at the VCF so you can heckle him in person.

Well, There Multibus-I, Multibus-II, STD bus, VME bus, Omnibus, Q-bus, B-I Bus, KIM bus, Exorcisor bus, FastBus, and that doesn't even scratch the surface.

Um, Sellam, are you sure you've not got 3.2/3.3 compatibility round the wrong way? The P5A and P6A PROMs that came on Disk ][ cards sold with DOS 3.3 (16-sector) can also handle the encoding used for DOS 3.2 (13-sector), but P5 and P6 PROMs supplied with Disk ][ cards can't handle the encoding used by DOS 3.3. There are a very few exceptions related to copy protected disks, of course, which is why some of us had switchable cards. -- Pete Peter Turnbull Dept. of Computer Science University of York

Sun 3/60

by a2k＠one.net

Hello, I'm trying to netboot my Sun 3/60 (from my Linux box). None of the HOWTOs I can find are very clear on how to do this. I've recompiled my kernel for rarp and nfs. My ethernet card works (00:00:C0:73:50:52) and my Sun is 8:0:20:6:10:35. When I try to run a command like /sbin/rarp -s 192.168.1.10 8:0:20:6:10:35 I get the error: SIOCSRARP: Network is unreachable . Any ideas? I think I have the correct kernel for the Sun, but that shouldn't matter -- it should at least try to talk to my Linux box, right? When I do >b le() on my Sun, it says Boot: le(0,0,0) Reqesting Internet address for 8:0:20:6:10:35 Any ideas? Thanks, Kevin ------------------------------------------------------------------------------- "It's you isn't it? THE BASTARD OPERATOR FROM HELL!"

Russian computers in hand :)))

by adavie＠mad.scientist.com

I wrote a while ago about Russian microcomputers. A couple of days ago I received my first two, and throught I'd write a brief description to the list. "Microsha" Appears to be a (souped-up) Spectrum clone in functionality, but looks totally different. Quite cool, actually... Keyboard unit in dirty yellow (Atari 800-style colour and basic appearance) but much flatter (about 1.5" thick). Red and blue keys in a really weird cyrillic layout. Each key has two labels, shown in pairs here. Many of the Cyrillic letters are unreproducible in ASCII, so I'll enclose a best guess in [...] The first of the pair is the TOP marking on a key, the second is the lower marking. Top row: (;+) (1!) (2") (3#) (4[circle with 4 prongs]) (5%) (6&) (7[triangle]) (8[left bracket]) (9[right bracket]) (0) (-=) (red: cyrillic [GT]) (red: cyrillic [AR2]) row 2 ([backward n with accent][right square bracket]) ([CH]C) (yU) (KK) (EE) (HN) ([G]G) ([sch][left square bracket??]) ([sc??][right square bracket??]) ([zh]Z) (XH) (:*) (red: [PS]) (red: [VK]) row 3 (red: yC) ([ph]F) ([bI]Y) ([B]W) (AA) ([P]P) ([R]R) (OO) ([L]L) ([D]D) ([??V]V) ([3]\) (.>) (red: PyC LAT) row 4 (red: [HP]) ([backward R]Q) ([sort of y]^) ([C]S) (MM) ([bacward N]I) (TT) ([b]X) ([b with bar]B) ([circle with half plus]@) (,<) (/?) ([b with bar overhang left]_) row 5 two small space keys for left/right thumb. Keyboard has a "keypad" section at right, with contents left diagonal up arrow, F1, F2 left arrow, up arrow, right arrow F3, f4, f5 down arrow, CTP What a bizarre organization!!! Keys are i correct positions - size differences confirm this. anyway, the gist of it is that the keyboard isn't QWERTY, but more like CUKENG It looks so very alien. Weight: abot 2lbs at a guess. Unit has an expansion interface at back (RAM?) which plugs in at right angles (ie: a bit like a cart slot on an Atari 800, again). Several other interface ports on back, the most interesting is a square unit simply marked (interface 2) with a 3 x 10 female connector. I have the manuals and power supply for this machine. I'll do a picture if there's any interest. I also have about ten cassette tapes of original software for this one. The other machine is a PDP-11 processor-clone machine called BK-0010 It's in original box, with all documentation. More about that later, if there's any interest. Cheers A

I see there are floppy diskettes being auctioned off on eBay. I remember too that there was some discussion about where one might get some hard-sectored diskettes. Well,folks, I have a box of new ones! Though the box was ruined, the plastic bag inside protected the media, so they were undamaged by the moisture which got in due to a damaged shrink-wrap on the box. Anyone interested? Dick

The only dos3.2 disk I've ever seen was/is a diagnostic disk from call-APPLE that i got in a box of materials i got from someone. Prodos can be used with any apple ][ with 64k and an autostart rom. There is a bug in version 1.1.1 that can trash track 0 but I've never had it happen. Later versions do not have this problem. I think it's prodos version 1.8 (or is it 2.0) that won't run on a ][+ anymore.

ASR-33 Local Mode "OK"

by cmcmanis＠mcmanis.com

Yipee. So after only two steps in the "clutch trip area" adjustment pages I've restored "normal" operation to the reader. Per the manual I loosened the armature extender, rotated the typing unit to the "stop position" and adjusted the extender for the correct distance (page 7, adjustment RRA-2) and once complete the reader returned to normal function. The bulk of the problem was, as Tony surmised, that the arm was now too far forward which did not allow the linkage to "catch" when the reader was turned off. Once adjusted the reader starts and stops under switch control. Now to hook this puppy up to the 8/E and see what I can make it do! (acutally eventually I'll get to the point where I read in FOCAL-8 but for now the TTY test loop would be just peachy thankyou very much. --Chuck

Odd glitch in a PDP-8/i

by jimw＠agora.rdrop.com

Ok, here is one for the true wireheads among us. I finally got some time to start working on the PDP-8/i in my collection, and started keying in some test programs with the intent of getting the timing on the TTY interface tweaked in so I could load some serious software, and found that the old beast seems to have an odd problem. See if anyone has hit on this one and has a suggestion... I can't seem to write into location 0 on any memory field?!? Regardless of what I write into the location, it always reads back as 0000. I can write into any other location, and all of the primary logic functions seem to be ok... (I can load/run programs as long as they don't need location 0) The 'write all zeros' test program (that org's at location 4) runs as expected... Thots, suggestions, comments, eek!?! -jim --- jimw(a)computergarage.org The Computer Garage - http://www.computergarage.org Computer Garage Fax - (503) 646-0174 >>> Coming soon to www.computergarage.org - the CBBS/NW on-line archives >>> Coming to VCF III (2-3 October 1999) - CBBS/NW live!

Several other interface ports on back, the most interesting is a square unit simply marked (interface 2) with a 3 x 10 female connector. I have the manuals and power supply for this machine. I'll do a picture if there's any interest. I also have about ten cassette tapes of original software for this one. The other machine is a PDP-11 processor-clone machine called BK-0010 It's in original box, with all documentation. More about that later, if there's any interest. Cheers A

Just scored an IMSAI

by allisonp＠world.std.com

<>There are only three voltages on the bus, +8VDC, +12VDC, and -12VDC, whic <>in reality are usually closer to +10~12VDC, +16~18VDC, and -14~18VDC. A good way to soft start a old powersupply that is also short safe is a 100-200W 110v (or equivalent for other countries) in SERIES with the 110v power. If the supply is shorted you will get a bright light, if it's ok it will Dim gradually or quickly to a dull glow or less. Works well for forming caps that arent totally gone. It's cheap and easy to make. Whille the lamp is in series with the source you can check the unloaded powersupply voltages, if the look good you can use an auto 12V bulb for a 1A load or a headlight for a 5-8a load. Allison

Just scored an IMSAI

by bill＠chipware.com

Well, much to my amazement, at lunch today, I got an IMSAI 8080. In beautiful condition, a few small scratches, almost no dust. Hasn't been up in years. I know we've done this before on this list, but... Where should I start? I figure: 1) pull all cards. 2) attach dummy load and check PS voltage and amperage. (What is an appropriate dummy load?) 3) check front panel mechanically. Use an OHMmeter to be sure that all switches are opening and closing correctly? I seem to remember that some people said that front panel disassembly/assembly is tricky. 4) install CPU and see if it "lights up"? Thanks, Bill Sudbrink

>Thre is no "original" Apple 1 case Right! We had 5 of them, no cases and the thing was a kit! Oh God, why did we get rid of them? We mounted them behind a wall with cut-outs for monitors and a shelf for keyboards and charged kids, mostly adults, to play breakout etc. Sold a lot of computers that way. "Hey kid, do you know that is a computer, and you can buy one for your own?"

Just scored an IMSAI

by edick＠idcomm.com

I once found a handy gadget for seeking adjacent line shorts on the S-100. It's essentially a board with the edge connector and little else, except that the pins on one side are connected. Since the lines tend to be laid out alternating from one side to the other, your audible squeaker will allow you to test one side at a time with the "other" probe tide to the opposite side. Finding shorts is really quick and easy with this. It's easy make, though several vendors sold them at one time. Fortunately, it's built without the part of the board which would prevent you from reversing it, so you can do just that. An unaltered board with the connections on one side shorted wouldn't quite work due to the mechanical offset which prevents you >from reversing a board.

I'e got an 8MB "ramdisk" board I built back in about '85 when the 256k's were new. This board is populated with a few LSI samples I got, together with a 4MBx18 section literally hacked (with a bandsaw) from a client's application circuit and tacked to the S-100 board. The packages were the "zip" package, which allowed for pretty dense layout. If I ever find this circuit again, I intend to rework the logic, since the memory is actually organized 1MBx72 bits, and I have a now-obsolete LSI from TI, the 74AS6364A, which is a gigantic LSI used to perform SECDED. Since it corrects and propagates in only 10 ns, I want to build in a hardware error scrubbing circuit and maybe a battery backup scheme. The board's still more than half empty, since the memory is on two mezzanine boards. - Dick > >Compupro made a M-drive, a 512k ram disk using 4164 devices.

This is a Super-whammodyne-OS machine." > "A Blah blah card." Life with S-100 boxes is a bit more complicated. Machines rarely kept their original factory configuration... and it was not uncommon to find every board in the machine made by a different company. With Compupro stuff, there are 5 main lines: 1.

"System Support" boards, with real time clock, console port, etc. 5. "RAM nn" boards, nn usually greater than 16. There are many other less common Compupro boards, like their video controllers, etc. Of course, there were literally *thousands* of S-100 manufacturers, and the above list only helps if you know you're dealing with Compupro stuff. >On a more serious note, I looked inside and there was: > A Z-80 cpu card. > 2 cards with 512K on them and were labled Disk something. Well, then, these are your disk controller(s). The "something" that comes after Disk is very important in identifying them!

Alto Mouse in "Pirates"

Bravo manual, page 33, "Bravo is controlled partly from the keyboard and partly from the mouse, the small white object with three black buttons which sits to the right of the keyboard". Also: "The three buttons on the mouse are called RED (the top or left-most one, depending on what kind of mouse you have), YELLOW (the middle one) and BLUE (the bottom or right-most one)." This implies that there were at least two mouse designs, one with three buttons from left to right, and one with three buttons from top to bottom. They both used a ball (not wheels).

70's sheet metal cases

by bill＠chipware.com

Did anyone else follow the link in the WIRED Apple 1 article? It goes here: http://www.grin.net/~cturley/gsezine/GS.WorldView/*APPLE.HISTORY/ Does anyone know the origin of this case? The color and general style of the sheet metal look about right for some OSI boxes. It also has a SOL-ish quality. Were there one or two sheet metal shops doing the cases for most computers in the mid-to-late 70's? I've sent this question off to the ex-OSI engineer I know, but he will probably take a couple of weeks to respond. Bill Sudbrink

More on the Compupro

by edick＠idcomm.com

I've been watching this thread with some interest, as I'm curious how large a board with 512Kbytes in 4116's would be. I've got some boards downstairs which have sites for 288 4116's on each. That's 576KB, though it's organized as 64-bit words with off-board SECDED which makes it 512 KBytes with correction. These boards are about 15"x22" which is quite a bit large for any of my S-100 boxes. The compupro boys often were fairly ambitious with their "features" and may have planned a different jumpering/multiplexing scheme for the power, addresses, etc, which were different once the 64K parts became available. However, considering what it took to make a memory board, even 64K parts would have left it a difficult task to fit all those DRAMs on the board, considering 1982 or so technology. I worked on a board from "little machines, inc" in '80 or so, which had on it about 250 IC's including some of the first sipps I ever saw on one side of the board (Multibus-1) and about 1000 passives and discretes on the other side. I think the combined RAM on the board came up to 512K, though the parts with which you could do that were not available. That board used every modern LSI and space-preservation strategy available at the time, yet was truly 10 pounds of SH*T in a 5-pound bag. The Godbout boys were really not inclined to use the most costly technology available. Hence, I doubt the CompuPro board in question held 512K of 4116's. The question remains, "What is it?"

That certainly seems to be the idea, though I'm puzzled as to why the board would say "Disk something" on it. All my Compupro ramdisk-type boards say "M-Drive" on them. -- 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

RSX-11M emulator for VMS?

by CLASSICCMP＠trailing-edge.com

>I was recently told that DEC sold an RSX-11M emulator that run as a process >on VMS for people who had old RSX code they wanted to run. Is this true? Yes, it is. This is the start of the SPD (see http://www.mentec.com/SPDS/vaxrsx.html for the whole thing): SPD 26.73.08 VAX-11 RSX, Version 2.5 is a member of a family of operating system and other software products produced by Mentec Inc. for the PDP-11 family of computers. It is available from Mentec Inc. or Digital Equipment Corporation subject to a software license issued according to standard terms and conditions. Description: Overview VAX-11 RSX is an emulator of the RSX Operating System family which executes on all VAX systems. VAX-11 RSX runs in compatibility mode on processors that support a PDP-11 instruction set subset in hardware or microcode, and also runs on processors without this support by providing its own software emulation of the same PDP-11 instruction set subset. VAX-11 RSX provides special capabilities which enable PDP-11 users to develop programs for execution in the following environments: VMS compatibility mode (hardware-supported or software-emulated) RSX-11M-PLUS RSX-11M RSX-11S Micro/RSX VAX-11 RSX also allows for the migration of many existing RSX applications to VMS. >And if so is it part of the hobbiest license? No, it isn't, though last time I checked it was part of the CSLG. -- 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

Alto Mouse in "Pirates"

by Innfogra＠aol.com

In "Pirates" a mouse was handed about, supposedly from the Alto. Was it an Alto mouse? Was the Alto mouse a three button? Who made it? I know the star 8010 Dandelion and 6085 Daybreak mice were two button mice as I have had several. Anyway I have a mouse that looks like the one in the movie and it is possible it came from an Alto. I would like to identify it for sure. Paxton
