OSI jigxaw puzzle(s)

by dogas＠leading.net

Hi all, I've got a few Ohio Scientific pieces and would like to know what I have and also what I'm missing. ( pictures at: http://users.leading.net/~dogas/osi.html ) The first computer is a c4p. it has a keyboard, power, i/o board (with some db9 and db25 and 3 sockets) and something like a backplane (no cards) bus board... Please check out the page above. The second computer(?) is a OSI 600 cpu with keyboard onboard. Attached to that was an OSI 630 and attached to that was an OSI A15..... OK, where can I go from here? Thanks - Mike: dogas(a)leading.net

One thing I would like, is for companies to make (internal) service manuals & possibly other info too, available for old & obsolete products which they do not support any more. After five years say, the company may not even be supporting the product at all (i.e. not providing a repair service), so I can't see how releasing the info could harm them. Though the proportion of people interested in this info would be small, I'm sure some good publicity spin could be given to doing this. And it needn't be expensive at all; just converting the documentation to PDF format (or scanning it if only paper copies are available) and putting it on a web page would be enough. Does anyone know of any companies that have done something like this? -- Mark

Video standards (was Re: digital cameras)

by roblwill＠usaor.net

Does anyone know if the U-Max or the V2000 were marketed in the US? I've never seen (or even heard of) anything like it. Does anyone know how much one might cost if I could find one? I like working with the older video equipment (mainly because I can fix the stuff) My only VCR is an 80's top-loading GE, complete with _wired_ remote :). The only reason that I bought the JVC VHS-C camera was because the heads went bad in my old camera (the kind with the separate camera that plugged into the 'VCR' that hung from a shoulder strap). ///--->>> -Jason Willgruber (roblwill(a)usaor.net) ICQ#: 1730318 <http://members.tripod.com/general_1> -----Original Message----- From: Tony Duell <ard(a)p850ug1.demon.co.uk> To: Discussion re-collecting of classic computers <classiccmp(a)u.washington.edu> Date: Thursday, July 15, 1999 8:09 PM Subject: Re: Video standards (was Re: digital cameras) >> >> On Thu, 15 Jul 1999, Hans Franke wrote: >> >In fact, this is also why I don't like VHS - maybe good >> >enough compared to a noisy aired NTSC source, but just >> >crap, compared to an U-Max or V2000 (I still use V2000 >> >tape machines - still equal to any S-VHS stuff after more >> >than 10 years of development ...).

VAX 11/750 Help!!!

by vaxman＠uswest.net

Hi, I recently acquired a VAX 11/750 with a bad power supply (sigh)... Does anyone have schematics for the power supply (H7104-C) they would be willing to loan/sell/give to me? I have a schematics for several other parts that I can loan/trade for them (including the CPU boards). Alternatly, does someone have a part number list for the 750 documentation? I have pulled what I can off of DAS, but it is pretty slim pickings. Finally, I am considering purchasing the MDS set on microfiche, but I DEC isn't able to supply me with any information on what is in it, specifically whether or not the documentation for the 11/750 that they don't currently sell (as hardcopy) is in it or not. Or possibly the PDP fiche set. Anyone have suggestions? Someone posted a while ago they had a list of documents from DEC labelled 'internal use only', could you see if there is a part number for a 750 printset in it? Thanks, clint PS I am putting together a list of spare boards/documents. Anyone want a set of VT100 printsets?

Did anyone ever try this: I have a JVC VHS-C camcorder that has full-auto settings (leveler, focus, lighting, etc.). It also has a snapshot feature, where it'll capture a frame. Use the video camera to take 'pictures', then connect the video output to a good quality video capture card, and 'capture' the still shots. Has anyone ever tried this? I was thinking this may be possible, since I already have the camera, and I can get a vid cap card for about $50 ///--->>> -Jason Willgruber (roblwill(a)usaor.net) ICQ#: 1730318 <http://members.tripod.com/general_1>

PDP-10's and Compuserve History

by CLASSICCMP＠trailing-edge.com

> Speaking of Compuserve, what is its history? I think this goes back earlier than you wanted (to a time before home micros), but here's an excerpt from a summary written by Sandy Trevor [70000,130] I found at http://www.inwap.com/pdp10/compuserve.txt **** This may not be exactly what you had in mind, but it is a pretty accurate summary of how 10's have been used at CompuServe over the past 17 years. I hope you can use it... anyway, please do keep me updated on your project. (If you want changes, or more material, just let me know). Also, if you do decide you want to use this, I'd like a chance to edit it a bit before giving you a "final" version. So please consider this a prelimary version... --Sandy We Call Them 10's - A Brief History of 36-bit Computing at CompuServe - Alexander B. Trevor August 31, 1988 CompuServe has one of the world's most powerful remaining thirty-six bit computing facilities, but got its first PDP-10 almost by accident. While I was a graduate student at the University of Arizona's Analog Hybrid Computer Lab (AHCL) in 1969, I discussed with two other students the idea of starting a time-sharing company after completing our degrees. We had all gotten to know a PDP-15 intimately at AHCL, so it was the obvious cpu of choice. But my choices in late 1969 were the Army or Canada. I chose the former, which put me behind a 360-40 in Saigon instead of a PDP-15 in Tucson. Meanwhile, my two AHCL friends, Dr. John Goltz and Jeff Wilkins, went to Columbus, Ohio, where they intended to computerize insurance processing for Golden United Life Insurance with (of course) a PDP-15. Before the 15 was delivered, however, DEC called up Dr. Goltz and told him that for only "a little more" he could have a KA-10. The prospect of having all this power was irresistible. Though he liked to distance himself from those of the sales persuasion, John skillfully sold the board of directors on the idea of spending the extra money to buy the PDP-10 and thereby gain the excess computer power to be able to launch into timesharing. Of course, it was a terrible time to get into this business. GE, Tymshare, Cyphernetics, and First Data (to name just a few) were already well established. The timesharing subsidiary of Golden United took the name "CompuServ Network, Incorporated" and started developing its first application, LIDIS (Life Insurance Data Information System). They had a KA-10 with all of 80K words of memory, two RP02 disk drives, and a few ASR-33 teletypes. The "C" series of TOPS-10 monitors that was available in 1970 supported disks, but as little more than circular DECtapes. Still, CompuServ made LIDIS work, and began attracting other clients. From the beginning, CompuServ tried to improve upon the standard DEC offerings. A first step was to hire two of the engineers who installed the machine: Bill Spellman and Tom Shelton. Tom would look at the the lights of an ailing KA for a minute or two (KA's had MANY lights), then go in back and change one or two boards. Usually, he fixed the machine on the first try this way, notwithstanding having been hauled out of bed at 3 a.m. A second step was to improve TOPS-10. At that time DEC included operating system sources with every machine. You needed them too: the early releases of TOPS-10 did not terminate a job if someone hung up without logging off. Thus, the next person calling in on that line found himself in the previous user's job, with access to all his files and privileges -- the infamous ghost port. Needless to say, customers got pretty upset when this occurred, so we fixed it quickly. Some monitor hazards took longer to surface. One morning, when the engineers looked at the KA, strange patterns were dancing across the console lights. Spellman was about to shut down the machine, when Steve Wilhite grabbed him and told him it was "just a little program I wrote." The next day, the LIGHTS UUO (CALLI -1) was disabled. Another motivation for modifying the operating system came with the first release of the "D" series monitor -- the first one with a real file system, including the beloved MFD, UFD's, RIB's, and SAT's. The first "D" monitor did not work for more than a hour at a time. John Goltz stayed up for three days patching the "D" monitor well enough so that calls from our customers no longer included threats of bodily injury. I seem to walk into things right after the fun. I went to Vietnam right after the great Tet Offensive of 1968. I joined CompuServe in 1971, right after the "D" monitor crisis. (It is still unclear to me which of these two events will turn out to be the most significant.) In any case, when I joined CompuServe in late 1971, they had two KA-10's, each with four RP02's. My first task was to write UNSPOL (DEC's spooling software was not yet available). Our machines were getting bogged down with jobs running "GLOM" - a little routine that continually tried to assign the line printer. We wrote most of our own utilities, either because we wanted features not yet available then from DEC, or because the DEC equivalents were not compatible with our monitor, which was rapidly diverging from standard TOPS-10. Or maybe we just liked to be different. Early on John had written a new EXECUTE that used sixbit command files instead of the DEC standard ASCII (to save disk space). Of course, this required changing all CUSPS (Commonly Used System ProgramS) and compilers. (Back then, programmers were cheaper than disks). The monitor's command decoder was another area of great change. We perceived GE as our prime competition, so many things were done to make former GE clients feel at home -- including the "OK" prompt, an imbedded line numbered editor in the monitor, and having Steve Wilhite write a Basic compiler in Macro-10 from scratch. At that point we didn't know that a compiler was too big a job for one programmer, and fortunately neither did Steve. Emerging from the dark back room we called the "cave" only to grab a line printer listing or an occasional sandwich, he got it done in ten months, using an ASR-33 and our FILGE editor. Everyone loved his Basic, but I'm not sure how many customers really switched from GE because of it. During this period we learned to get the most out of the KA -- doing things such as using MOVEI A,N(A) for addition because address arithmetic was faster than the regular adder on the KA. CompuServ's two KA-10's were each connected to 680i front-ends through DA-10 interfaces. The 680i was a PDP-8 that had been lobotomized to handle communications. UART chips were not yet in common use, so the 680i's had to handle asynchronous characters one bit at a time. One disadvantage of this configuration was that communications ports were tied to a single host KA. For example, the remote lines from Dayton and Cleveland were connected to System 1, while Columbus and Detroit were on System 2. So what did you do with a customer with offices in all four cities? My second major assignment at CompuServ was to solve this problem. Clearly, some kind of switch was needed so that a user coming in through either 680i could access either host. And what was Dr. Goltz's choice for the switching computer? Right, a PDP-15. It was an 18 bit machine (exactly half the PDP-10 word length), fast (1 MIP), and fortuitously, compatible with the DA-10. Now, this PDP-15 that I had to develop into an intelligent communications switch came with 8K of memory and an KSR-35. That was it -- no mass storage, not even a Dectape. Since I did not relish doing development on paper tape, I decided I had to use the 10 for development. Since there was no cross assembler for the PDP-15, I wrote macros for each of the PDP-15 instructions and used Macro-10 to generate PDP-15 object code... a use that probably even exceeded the wildest fantasies of Macro-10's developers. In 1973 CompuServ moved to a new custom building in Upper Arlington, Ohio, and upgraded the KA's to KI's. By July, 1974, we had seven KI's and were using them not only to support a thriving time sharing business, but also to heat our office buildings. The RP02'S and RP03's were all retired in favor of "huge" 200mb Ampex and Memorex 3330 disks connected through Systems Concepts SA-10's. John Goltz continued to develop his operating system (now called the "E" monitor), including a class scheduler. But by 1976 a more pressing problem arose. DEC had released the KL-10, but it seemed prone to overheating (ECL does generate a lot of heat). Dr. Goltz felt we needed a faster processor, but the KL was unsuitable. We looked at Foonly's F1, but were uneasy about their ability to actually produce machines. So, with two of our best engineers, Doug Chinnock and Wilson Mowbray, John Goltz set up an R&D center in Tucson, Arizona, to build a better 36-bit computer. In 18 months, they had several large boards, microcode that avoided all the DEC patents, but were still a good year from having a production machine. Jeff Wilkins was running short on enthusiasm (and cash) for the project, and it looked like DEC had really solved the KL-10 heat problem with the DEC-System 20 configuration. Not only that, but the price of the 2050 was at least $100K lower than the 1090. Internal memory and devices on RH-20's seemed not only more efficient, but saved us from having to add cache sweeps to our monitor. If we could run our operating system on this machine, it might make more sense than finishing the "JRG-1" processor. After several trips to Marlborough, I got DEC to agree to sell us DECSYSTEM-20's with TOPS-10 licenses and DX-20's. The licenses eliminated any question about running any of the TOPS-10 utilities, and the DX-20's let us connect the orange KL-10's to our STC tape pool. Our first 2050 worked beautifully, so the JRG-1 project was terminated. Sadly, not long afterwards, Dr. Goltz left CompuServe. We had been buying Ampex's ARM-10 memory for the KI's for years, so we asked them what they could do for the 20. Despite dire warnings from DEC engineers that the S-bus could not possibly support a physically external memory box, Jay Canel of Ampex came to CompuServe with the first ARM-20 box, plugged it in to our 2050, made one timing adjustment, then we watched it run for the next six months without a failure. Our next 2050 enhancement was to design a channel interface. Since the Massbus was patented, and DEC was not granting licenses, we built directly to the C and E busses. Our "MBX-20" let us connect 300 mb SMD disks to the 2050 using a Telefile controller, instead of being limited to the 200 mb RP06 (all that DEC offered then). By 1978 we had two computer centers - the one in Arlington full of KI's, and one in Dublin, Ohio, filling up with 2050's. We were not yet ready to abandon the KI's, but wanted some more horsepower out of them. Wilson Mowbray designed a hardware cache memory for the KI which yielded a 30% improvement in KI speed. Later, Wilson designed a switching regulator power supply for the KL, which halved it's power consumption. Roseann Giordano was so impressed that she sent some DEC engineers to look at it. They liked it, but the KL was too near the end of its product life cycle for DEC to make any changes, even though we offered to give them the design. By 1980 PC's were beginning to assume many of the tasks formerly done on timesharing systems. Many of our old timesharing competitors (Cyperhnetics, First Data, On-Line Systems) had been acquired or disappeared. CompuServe (which had added the "e" by this time) was acquired itself in 1980 by H&R Block. Block wisely let CompuServe continue with all its plans -- including rolling out a service for PC users modelled loosely after the European "videotex" services. Developed almost clandestinely shortly before the Block acquisition, it was called "schlock timesharing" by the "professional" commercial timesharing sales force. Initially released as "MicroNet" and later as "the CompuServe Information Service," it grew to be 50% of CompuServe revenues by 1987, while commercial timesharing evolved rapidly toward databases, email, and commercial videotex. With Block providing financial backing, ComuServe entered the acquisition business itself. It's first acquisition was Software House (the authors of 1022 and 1032 DBMS systems.) While solidifying our position in the 10 world with 1022, we also had taken a first step into the world of Vax with 1032. There was some pressure from various quarters to "upgrade" our hardware to something more modern -- like Vaxes, for instance. However, by 1986, KL's were less than $20,000; we had our own monitor and most systems software (except LINK-10 and BLISS-36); we were able to use current technology disk drives; and we had 100+ manyears of applications software in XF4 (our own ten-based extended Fortran) and Bliss-36 -- so how could we justify a change unless 36-bit cpu's became unavailable? To be sure that didn't happen, we ordered a Systems Concepts SC-30 from Mike Levitt. It arrived in late 1987 (a bit behind schedule), but came up and ran our operating system with no more than the expected number of microcode bugs. (We used Tops-10 paging, which Systems Concepts had not fully tested before). It worked well enough that we ordered a total of 10 SC-30's - four of which are up and running as of this writing; the remainder to be delivered next year. The venerable KI's (the last of the "lights mentality" machines) are being phased out to make room for the SC-30's... (and yes, a few Vax 8550's have snuck in too, for some new applications already written for Vax). New interfaces are being designed for both the KL's and the SC-30's to support faster disks, optical storage, and new archival storage devices. Applications development in Bliss-36 and XF4 continues unabated. At CompuServe, at least, 36-bit computing has a bright future.

digital cameras

by lemay＠cs.umn.edu

I've been seriously considering buying a digital camera for some time now. I assume others on this list already have these in order to photograph some of their computer items, so i thought I would ask which features are most important. And which features you really wish you'd spent extra money for. It seems to me that a macro-focusing feature, which allows you to manually focus at very close range would be very useful. Or can you get by with a 3X optical zoom in order to get detailed shots of computer boards, or the insides of a computer, etc? How important is high resolution? Is a 640x480 camera with 10X zoom much more useful than a 1280x960 with 3X zoom and no macro focusing? I'm really only interested in photographing computers and circuit boards, I assume anything that can handle that to my satisfaction will be able to handle the occasional photo of my niece and nephews, etc. -Lawrence LeMay lemay(a)cs.umn.edu

They are labeled: VMS V5.0 BIN TK50 BINARY and VMS V5.0 BIN TK50 MANDATORY UPDATE I can probably handle the update after I install VMS (something like @SYS$UPDATE:something-or-other). The first tape boots and takes me into stand-alone backup. At that point I'm lost. Any ideas? Thanks, Bill

A chkdsk with version 2.1 can't find any problems. Could the original setup operation have disabled the disk set? I have tried all reasonable country/keyboard combinations. Anybody have any leads?

There's nothing incredibly complicated about getting a fixer-upper back into reasonable shape. If a shutter is truly worn out (not impossible for something that's been in professional service for several decades!) entirely new shutters/apertures are still available. See, for example, http://www.skgrimes.com/ . And new bellows, ground glass, etc., are all available for a price. It certainly is cheaper to get a "clean" used camera than a really ratty one where all the parts need to be replaced, but there are ones "in-between" where a little bit of TLC is all it needs to become usable. >A large format camera is something that I want to have a go at making >sometime.

"a few hundred $"?!? What are they on E-BAY?!? I got my >cameras back when prices were reasonable (60s,70s), as in $20 for Graflex. Well, my introduction came in the late 80's and early 90's, when I started getting into cameras and darkroom stuff. A few hundred dollars will still (my prices are based on what I see at Camera shows and dealers, not from E-bay) buy you a clean Crown Graphic with a perfectly operating lens, some film holders, and a roll-film or polaroid back. I do see real ratty ones for $10-$20 at flea markets, with almost certain holes in the bellows and gummy shutters on the lenses, and usually with visibly broken rangefinders. These are things that can be patched up, certainly, but I wouldn't turn an absolute beginner onto such a fixer-upper when for a very reasonable price you can get a clean one. As a step up from the Crown Graphic, you can get an excellent used monorail view camera with full movements for just a little more money. I got my Calumet 4x5, 20" bellows extension monorail with a bunch of film holders and a not-so-bad 210mm Japanese process lens from the mid-70's for $250. The process lens, not surprisingly, is *excellent* for macro work. Brand new setups are available from Calumet photo today (see http://www.calumetphoto.com/ ) for not a lot more money. >I got my Linhof Technica III from one of the largest camera stores, but it >was in a paper bag labelled "most of a Linhof $20", and I had to make some >parts. If someone wants to make a camera, the Bender view camera kits are an excellent project. See http://www.benderphoto.com/ . I wouldn't trade my Crown Graphic or my Calumet for one, but I could see how someone would prefer one they built themselves. The Bender camera kits are *real* pretty when you're done, much nicer looking than my gunmetal grey Calumet or heavily used Crown Graphic. But I'm sure my Crown Graphic and Calumet have stood up to abuse that would've turned the Bender into splinters. -- 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

New toy!!!

by rigdonj＠intellistar.net

I got an e-mail recently from someone offering me an Esco 31 survey calculator. I'd never heard of one but I decided to take a chance and bought it sight unseen. It came today. The seller forgot to mention that it said Tektronix on the back! Yeap, it's a rebadged Tektronix 31! Does anyone have some instructions for one? Does anyone know where to find tapes for these? Joe

'Gloat list'

by kyrrin＠bluefeathertech.com

Ok... you can blame John Lawson for reminding me about this. I just got back from my annual scrounge trip to the Bay Area. Said trip netted me a good-sized pile. While not all of it is "classic," I figure it's worth posting. * Upgrade components for my own system to K6-2/400, etc. * A Digilog 300 datascope. Haven't fired that one up yet. * My very first DEC Alpha system -- specifically, a 3000/600. * Two Wellfleet routers. * A Livingston 'Portmaster' IRX/Firewall router. * A stack of DEC'ish boards, including a pair of Dilog DQ132's, a DQ686, and a pair of Sigma RQD11E QBus ESDI controllers. * A collection of pre-divestiture Bell System technical manuals (Station Services, Key System Services, and Data Services). These are the white paperbacks with the yellow/blue skunk stripes and the pre-breakup Bell logo. * A Sorensen 0-40V/25A power supply (Heavy!) * A nice tabletop VME chassis that still had a Force Computers 68040 CPU board installed. * A big Cabletron network hub chassis with 60(!) 10Base-T ports in the form of five 12-port cards. I got it 'cause the backplane is rated for FDDI, and I figure that means I can also use 100Base-T on it if I can find the appropriate card. * A pair of Sun SPARCStation IPC's. * Keyboard/Video/Mouse extender for PCs. * Adobe Acrobat 4.0 for around $80. That's all I can think of at the moment. Some of it is for future projects, and some for current ones. All I can say is I'm glad to be back. That was a long trip!

Hi Tony, >I can tell you a little about some of the Philips P800 machines.... >....Feel free to ask specific questions on the P850 or P851. I have the >manuals, and I think I know where I put them :-) Thanks very much for the reply, that's increased my knowledge of these machines by at least 100%!!!! I'd forgotten that they existed at all until I spotted a message from you mentioning them. ISTR seeing one sometime around 1978 when I visited a computer installation as part of my computers course at school, but that's pretty much all the contact I've ever had with them. My main questions at the moment are, where should I start looking to acquire one and (if I had a choice) which machine would you recommend to try and get hold of?

Classics for sale! (muMATH)

>Just yesterday I handled a copy of the doc's for the CP/M version. This >implies that it was a CP/M program. I doubt that MuMath/MuSimp was >generated as an apple version as well, though stranger things have >happened. muMATH on the Apple II is not CP/M, nor is it DOS 3.3 or ProDOS. It uses its own disk operating system which is a bit of a pain if one wanted to extract files from the system disks. However, the disks are still 16-sector and can be made into images for emulators or backed up easily. This was done so that the system would run on an Apple II+. DOS 3.3 used too much memory so something simpler had to be found and it predates ProDOS. I still find it amazing that muSIMP could run at all on such a small system. Was muSIMP ever ported to anything "larger"? Ron Kneusel rkneusel(a)mcw.edu Auction is still on, some good systems still not spoken for: http://net-24-42.dhcp.mcw.edu/auction/auction.html

Hello everyone.... I was just going through some old boxes in my basement, and found some stuff that I was supposed to pay shipping on. I know that there was someone from this list that sent me 3 IBM 4869 floppy drives... I think that was all from the list (I hope) Could you please contact me with your address and the amount of shipping (I think it was somewhere around $10?)? ThAnX (I've gotta keep better track of this stuff...) ///--->>> -Jason Willgruber (roblwill(a)usaor.net) ICQ#: 1730318 <http://members.tripod.com/general_1>

<What is the approximate resolution of a 35mm frame? Good enough that you can project it to greater than 8 foot by 8 foot image and still not see the grain with reasonable film. For printing you get smooth images at greater than 1000 dots per inch and photo typsetters are around 2500 DPI. digital cameras at 1024x768 are better video camaras (400 V by ~250H <~500 with interlace>). When you take 1024x768 and stretch it to 10.24"x7.68" the image is only resolved to 100 DPI and image smoothing may help but only to a point. Allison

It is a wave property of light. A point sourse of light can only be focused to certain disk size. The Airy disk is defined as 1.22 * wave_length * f_ratio. The smallest distance that one can call two disk as being separate is call Dawes criteria and is when the two spots are 1 Airy disk apart. Other shapes of objects will have sightly worse problems of separation but this is a good rule of thumb for light. It is interesting that stopping a lens down, makes a higher f/ratio and makes the spot size smaller. Stopping the lens down also improves depth of field. Exposure time also goes up. You just can win.

>What is the approximate resolution of a 35mm frame? A typical film has a resolution of 50 to 200 lines per millimeter (films intended specifically for high resolution technical use may get twice this, at significant loss in tonality). A 35mm full frame is 36 mm wide by 24 mm long, or 3600 x 2400 pixels assuming a "pixel" is a "line" and 100 lpmm resolution. But as pointed out, it could be twice that resolution or half that resolution depending on the film. The better lenses, when properly focused and used on a tripod, can resolve better than 100 lines per millimeter. Your typical point and shoot lens will be lucky if it can resolve 50. Now compare this to what a 4 in x 5 in "large format" camera can get: assuming only 50 lines/mm (something easily done with an 60 year old lens), you get 6250 x 5000 resolution. Not bad for technology that was mature over a half century ago. -- 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

8080A I/O Pin?

by allisonp＠world.std.com

<What pin does the 8080A (raise/lower?) to indicate <that it is doing an I/O read/write instead of a memory <read/write? Also, does anyone have a copy of the IMSAI <MPU-A Rev-4 schematics that they could scan and send me? Your thinking 8085... 8080 is very different. There are two pins on the CPU: WR/ (pin 18) indicates precessor write (memory or IO). PDBIN (pin 17) indicates a IOREAD, MEMORY READ, INSTRUCTION FETCH The latched 8bits from the data bus at Sync(pin 19) time tell if the operation is D0 SINTA Status interrupt acknowledge D1 SWO Status write out D2 SSTACK Status Stack operation D3 Shlta Status Halt acknowledge D4 Sout Statue output (IO output operation commences) D5 SM1 Status M1 state (instuction fetch) D6 SINP Status input (IO input operation commences) D7 Smemr Status memory read Those status signals only indicate the next bus cycle activity and must be cates with Sync (psync on the bus), PDBIN, WR/ before the whole mess makes sense. Intel later created the 8228/38 chips to do this. Otherwise it takes a good handful of gates to sort it out. I have the Bursky book, no scanning ability. if you can altair docs the 8080 and 8212 status latch portion of the altair CPU are the same. Allison

New drive belts for 3" floppy drive?

by mark_k＠iname.com

Hi, Can anyone confirm that the Spectrum +3 (I have a couple with "broken" floppy drives) uses the same drive mechanisms as the Amstrad CPC6128? If so, I will order some replacement drive belts for my +3s, since the belt perishing is almost certainly the problem. With this in mind, does anyone else need some replacement drive belts? The price is about 1.75 pounds each (I'm in the UK) if I order five or more. If so, please let me know. -- Mark

Sun

by rhblake＠nospam.bigfoot.com

I have in my possession a Sun 4/110 main unit in unknown operating condition. It appears to be made as a desktop unit but has a factory set of pieces that make it stand upright on the floor. As far as I can tell it was pulled directly from service but has no mouse, keyboard, monitor, etc. it doesn't appear as if anyone has gotten inside either so i'm assuming it's a complete unit. Anyone want to make me an offer on this? I am always in need of common PC hardware that I could trade for the thing, especially SCSI cdroms and hard drives (preferably 1gb or bigger). Remember that you'd be getting basically a "pig in a poke" as I have no equipment to use to set it up or test it with so it's strictly on a chance that it might be fully operational. The unit is fairly heavy but probabl not more than 45 lbs. -- Russ Blakeman Clarkson, Ky USA Remove "nospam.' in email address to reply

Other Bazaar Boards

by amichael＠nortelnetworks.com

The John Bell 6502 board used to be advertised in the back pages of pre-1980 Byte magazines, along with a selection of other JB cards. I seem to recall the 6502 card was minimal-chip system essentially aimed at "embedded processor" type applications. So I don't think it came with a preprogrammed EPROM; you were expected to develop your own firmware for it. They had another bare board for a video display terminal based on an Intel 8085 (basically an implementation of the circuit in an Intel application note) and they also sold some low-cost interface cards for Apple II parallel interfacing using the 6522 VIA chips that were then popular in Commodore Pets. I remember building a couple of those JB interfaces for lab experiments. I wonder who "John Bell" was and whatever happened to him?

Daisy computer ?????????

by rigdonj＠intellistar.net

This is another oddity that I spotted Friday. It's a black box about 3 feet high by 1 x 2 feet with 2 chrome legs that stick out to one side with castors on the end of them. It has an 8" floppy drive near the top and a FH 5 1/4" hard drive inside. There were several WIDE ( 60 pin?) ribbon cables hanging out of it. Inside at the bottom it has a card rack with about 6 or 8 Multi-bus cards in it. The label on the outside says that it was made by Daisy. Any one have any idea what it is? Joe

(fwd) PERQ 2 requires new home

by ard＠p850ug1.demon.co.uk

This appeared on alt.sys.perq today - is anyone here interested? If anyone in the UK does rescue this machine (and I hope they do), I'd be happy to give some advice on sorting it out. Please reply to the poster below and not to me. -tony ---------------------------------------------------- I am the proud(?) owner of a Perq 2 system. Unfortunately it has come to pass that my house is not big enough for the both of us. It hasn't been booted for some years but made it all the way to 15 on the diagnostic counter when I tried the other day. I believe that spells hard drive trouble, which may or may not be fixable. As far as transport is concerned, I live about 30 miles SW of Cambridge, UK and it will be the responsibility of the new owner to transposrt it from there to wherever.

Can anyone ID these SEMI chips?

Hi everyone, I'm curious about identifing some chips. I have was appears to be a memory board made by "EMM". It also appears to be Q-bus, at least the power and ground seem to be in the right places to be Q-bus. Anyway, the board has 64 of these chips, and looking at the interconnection between chips, they appear to be arranged in 2 groups of 32. The chips are labeled: SEMI 4200ACC 7733 These are 22 pin chips, made in 1977, but I can't seem to find any chip manufacturer named SEMI or any reference to this 4200 number.

I see HUNDREDS of machine being scrapped every week and a fair number of them are unique. It's impossible to save any significant number of them. For example, just at that one place on that one day I found the Daisy, three HP 7906 drives, a HP 9830, a HP 9866 and a pile of Hetra machines, a complete Sun 4/260 and two stacks of smaller Sun computers. We got the stacks of Suns and we're trying to get the 260 and HPs. At least if they have to go it's better that their parts be saved to repair the ones that are left instead of being sent to the land fill. Joe > >

Since you seem to have gotten the answer to the Qniverter question, let me mention that if you are looking for _real_ RM03's, I have access to a couple of them in Dayton, Ohio.

(There's also a short rack with Fuji Eagles and an SI9900 and taller rack with a TS11). If anyone really needs one or two RM03's, I am fairly sure I can still get them. If I go get them for myself, I'm likely to part them out. -ethan === Infinet has been sold. The domain is going away.

Classics for sale!

by dpeschel＠u.washington.edu

This relates to Ron Kneusel's auction. Ron, I couldn't reply to you -- your rkneusel(a)mcw.edu address didn't work. Does the Apple version of muMath require the native Apple DOS or is it a CP/M program? Do you have a list of the Kaypro original software and the manuals? (It would probably be too much work to list the unoriginal software you're also selling.) Thanks, -- Derek

Thinkpad 850

by red＠bears.org

Hi; this is not strictly covered by the charter of the list, but someone on it mentioned running across them with some frequency, or at least once. As it turns out the 850 I paid a fair amount of money for with the intention of actually using it is a "pre--General-Announcement" unit---essentially a hardware prototype. This isn't that big of a deal, but there are some unresolved hardware issues with respect to AIX support which make the laptop difficult to work with. Can I ask the person who saw these units at auction to contact me off-list, please, with regard to acquiring another 850? ok r.

MicroVAX 3100 Problem

by CLASSICCMP＠trailing-edge.com

>Some questions for TK50 folks... > 1) Can you operate a TK50 when it is _only_ connected to power? Pretty much true. There are some states, where if you operate the load solenoid by hand, you can remove a 99%-already-unloaded cartridge. > 2) Which is load, button pressed or button out? Pressed in. > 3) What are the status modes on the light? Red light blinking fast = failure. Red light blinking slowly = rewind. Green light solid = tape loaded and ready. Green light blinking = tape moving. -- 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
