update to "here's the list..."

by edick＠idcomm.com

It's unlikely I'll do that, since of the many hundreds of boxes of 8" diskettes I owned at one time, there were only two of the hard-sectored ones. I recently had a local NRC contractor phone me up after a long chain of referrals, to inquire whether I could replace a drive for them and I had to ask them to provide me with a disketted with which to test the drives. I believe I had one partial box of Memorex diskettes which came with an old NBI word processor which used Memorex drives and an i8008, which , by the way, is now a "high-tech tie-tack" I occasionally wear. There was also an odd box (possibly new, possibly full) of 10-sector hard-sectored diskettes. I don't know what their use was, but I had some GSI/Siemens drives which could operate with either type and soft-sectored ones as well. In the unlikely event these turn up, I'll let you know. regards, Dick ---------- > From: Merle K.

FS: IBM PS/2 Model 70-386 (25 mhz) procesor boards

by rhblake＠bigfoot.com

I have 4 boards that go to IBM PS/2 model 70-386's, the 25 mhz version to find homes for. These are the smaller processor board that mount to J1 and J2 on the base motherboard and has the 80386DX-25 on it and has the socket for the 80387DX-25. If you have a bad machine, or just need a standard Intel 80386DX-25 chip, then this is for you! The picture listed at http://www.pc.ibm.com:80/bookmgr/pictures/s52g9971-picture-77-zoom.gif shows the layout of the entire board and the ones I have are the small board that #6 points to. The standoffs to mount the board are NOT included. All have been tested with and without a 387 math processor and function great. How much? $5.00 each plus a few dollars shipping. They don't weigh much so I imagine they should ship cheap. USA ad APO/FPO addresses only, payable by either money order or cash (if you trust the mail that much). If someone wants ALL FOUR right off the bat then I can go $16 for all of them, plus a still small shipping fee. Drop me a note by direct email and please include your zip code so I can guess-timate shipping. My guess is probably $2 will get one of these to most places in the lower 48.

There's a fair amount of documentation the corresponding software to which, sadly, had to be tossed with the other 50K or so 8" diskettes I have ditched over the past year.

Kip, I enjoyed your article. I have a IBM System 360 control panel complete with the 360 metal bar that goes above the panel. Let me know if you know anyone that would want to buy it ... it would be a great retirement gift or an excellent office piece. It is about 3' by 4' and would fit on a wall. Attached is a pic.

Wanted: TeleVideo CP/M machine(s)

by douga＠email.com

Greetings, I'm looking for a TeleVideo CP/M machine, particularly the TS-803 or TS-1603. If you have one of these computers, or one similar to this one (not including the portable), I'd be interesting in buying it. Or, if you have suggestions on where else I might look for one, I'd really appreciate it. These were great machines, but they're hard to find now! Actually, I may be interested in two of these, if they're available. This may turn into a crazy project, but I have the idea of taking one of them and replacing the guts with a standard PC motherboard/hd/ram/power supply combination to run Linux on it. The TeleVideo 803/1603 has a unique case, which would make for a great looking computer even today. The trick would be maitaining compatibility with the keyboard cable and monitor; not to mention fitting the components inside reliably. But what a coup it would be! Thanks. I'm in the Seattle area, fwiw. Doug Auerbach

So far, I've only found the one set of Dazzler doc's and software, and the software is on paper tape. I believe there's still one dazzler set floating around, though. I still have a few hundred 8" diskettes, of which maybe ten or twenty will be hard sectored, with holes on the outside of one box and on the inside of the other. I may never find these, however, as they were stored in a part of the basement now buried with "other" stuff. ONly time will tell.

by edick＠idcomm.com

I do have a boot disk for the 806. I'm not sure where it is at the moment, but it's within 10-12 feet of here for sure. Since I haven't used a CP/M box of any sort for a long time, I'd be afraid to guess how I'll replicate it. The 806's I have are 20's but that's a combination of a 20MB hard drive and about half a dozen bytes in the bios. I used to switch between a ten and a 20 by patching these bytes. Email me in a couple of days and I'll try to have a firm answer for you. ---------- > From: Merle K.

Noisy ST 251 HD

by allisonp＠world.std.com

<I am really glad to find I can use the ST-251 in my DEC <Pro 380 instead of the Quantum Q540, since the later drive <is rarer, older, and perhaps (in my experience) not too <reliable. And has a smaller capacity, of course, and is <a full-height drive. The ST251 is well known for it's bad bearings and spindle problems. The Q540 is known for running forever. The later know as a RD52 is very common and very hard to kill. I have about 8 of them (all good). Generally I will not use a st251 again... I spent to much time helping PC support at DEC with disk failures in VAXmates (st251s aka RD32) where the older st225 was rock solid. <Is there a better drive (MFM) with equivalent geometry? <(820 cyls, 6 hds, 17 sec) or maybe with 6+ heads and 820+ <cylinders (that might work, too?). Half-height would be <nice, like the 251, because if I ever get another HD <controller card, I can put two drives in my Pro 380 (only <one drive per controller card, and supposedly only one <per Pro chassis, but the 251 probably uses a lot less <power than the Q540, so two drives should be OK). the q540 is 8x512 (31mb)... and the 251 is 6x820 (40mb). Also the 540 is several times faster (voice coil VS Stepper). Allison

DEC Pro memory card upgrade

by djenner＠halcyon.com

Here's another Pro 380 question. I asked it on the pdp11 newsgroups and got no answers. Maybe you can do better here! Has anyone ever upgraded a memory expansion card (000034, plugs into slot 0-5 of the CTI bus) from 64Kbit to 256Kbit chips? (256KB to 1MB) You can easily do this with the memory card that plugs into the mother board--there's even two empty jumpers waiting for stuffing. Is it possible? If someone thinks they can do it, I'll gladly contribute a board for a proof-of-concept test. You keep the board as long as you tell me how to do it! Dave

Hi all. I'm feeling clueless at this point. I've found the CPM caldera site and downloaded everything that looked appropriate, but I'm completely unclear how to turn this into a kaypro boot disk. I've put a 360k PC drive on my PC in the hopes of using it to write the disk. I've also downloaded teledisk.

Introduction

by rickb＠pail.enginet.com

Greetings, Classic Computer Fans, I've just subscribed. I've heard about this list for a long time, and have been recommended to check it out by a number of folks, so...here I am. My name is Rick Bensene. I live near Portland, Oregon. Some here may know me from my old calculator collection (which I'll shamlessly plug here: http://www.geocities.com/SiliconValley/Lab/7510), which is my substitute for collecting old computers. (Calculators take up less space) I've been involved with computers since the early 1970's. I currently work as a technologist at a large Electronic Design Automation software company. I've always loved computers, and though I don't actively collect them, I am hoping to live vicariously through all you folks who are active in collecting. I have a few older computers that I've run across, mostly as orphans. These include a Tandy 100 (who doesn't have one of these?), a Tandy 600, a Sun 3/50, a Sun 4/360, A couple of Tektronix 6130's, a Tektronix 4132, and a Tektronix 4319. I worked at Tektronix for 13 years, from '77 through '90, so I have a particular affection for Tektronix equipment. I've used/administrated/hacked/programmed quite a range of computers, ranging from a CDC Cyber 73 and later Cyber 176 at Tektronix, VAX 11/780's running both VMS and 4BSD Unix, A Gould Powernode 9080 (interesting, all ECL machine with dual processors), a DEC PDP8/E(OS8), a DEC RSTS system (running on PDP 11/45), varios 11-based systems running RT-11, HP 2000C, E, F, and ACCESS timeshare systems, Apollo Domain OS (DN300, DN3000-series), Sun from as early as the 68K-based VME-bus systems to latest Ultras, early HPUX machines (700-series workstations), IBM RT workstation, IBM 360/30, early micros (Altair, IMSAI, North Star Horizon, ProcTech SOL), Commodore PET, TRS-80, TRS-80 Color Computer, homebrew stuff (8008, 8080 and 6809), Tektronix 4051, Tektronix 6130/4132, Tektronix 4081, Tektronix 43xx-workstations, Alpha Micro (from the early LSI-11-based days), an old (early 1960's) computer made by 3M (can't remember the model number, but I'll write up some memories about it for the list), a SCM 7816 (strange beast, a cross between a computer and a calculator), and of course, PC's since the original. I've programmed in FORTRAN, COBOL, just about all variants of BASIC, C, Perl, Pascal, and in assembly on PDP-8, PDP-11, IBM 360, Interdata 7/16, 8008, 8080, Z80, 6800, 6809, 8051, 8085, 8086, National 320xx, and 68K. I'm looking forward to sharing memories with the list, and, as mentioned, hearing about your memories, and all the great collector finds out there. Best wishes to all, Rick Bensene

here's the list . . .

by edick＠idcomm.com

Here's the list of S-100 hardware I've turned up in the last mess of boxes, etc to be unearthed in my basement and transferred to open air storage in my carport. This is only a partial list of what I've uncovered this afternoon, and an extended list will be available later today. There is other stuff, not yet inventoried, but that will be later, if at all. Cromemco 21-slot unterminated Motherboard in VECTOR cardcage - assembled but never used. MSC (later became XEBEC) 9391 5Mbps HARD DISK controller. This controller is functional and capable of handling 16 or fewer heads at 512-byte or 256-byte sector sizes and steps the drive at 3ms per step, which was typical back in 1980. This was the one we used most. XCOMP HDC 2-board set. These are set up for 8" drives only and require one write the BIOS patch or back end driver oneself. Franklin Electric 3-UART serial I/O board DC Hayes Micromodem-100 including documentation and software SSM IO4 2P+2S I/O Board with documentation. No software was provided since everyone wrote their own BIOS patches for it. North Star Z80A CPU card California Computer Systems 2810 Z80A CPU card, with monitor prom. California Computer Systems 2422 FDC for both 8 & 5.25" drives, with monitor/boot prom California Computer Systems 4-port serial card. California Computer Systems 64K DRAM card Vector Graphics 64K DRAM card Extended Processing "BURNER, I/O" board - Prom Programmer with UARTS and PIO not installed. Processor Technology "CUTS" cassette interface? board BIOTECH ELECTRONICS BCT800 graphics board - uses AMI 68047 chip and 12 2114's to produce 256x192 graphics and text. Cromemco Dazzler video graphics board pair - There are two, but only one set of doc's and software including paper tape. MITS Modem board - a MITS serial board with a "MODEM BD" rider.

Chinon XT SCSI host adapter card

by mark_k＠iname.com

Hi, I have a Chinon 8-bit ISA SCSI host adapter card, which came with my old Chinon CDS-435 SCSI-1 CD-ROM drive. The part number printed on the card is 66201UCSEP02. The only provided driver software is for the Chinon CD-ROM. To use other SCSI devices with this, I need appropriate drivers. What I want to know is, was any "universal" driver software ever made for this card, by which I probably mean an ASPI-compliant driver? If anyone has any idea, or a suggestion of where might be a better place to ask this question, please tell. BTW, Tony Duell would really like this SCSI controller; *every* chip on the card is simple 74-series TTL. :) -- Mark

Looking at my machine, I can see that the drive wheel for the tape drive is pretty funky. I haven't tried to use it (don't have a cartridge) but, it'll probably fail. Is there a common source for drive wheels? What about the cartridges? Thanks, Steve Robertson - <steverob(a)hotoffice.com>

His boss asked him to fix a 386 because of a quite spectacular Windows 3.11 crash. My friend couldn't even format the hard drive using the traditional MS-DOS format programs so he tried the Packard Bell diagnostic disk that had come with his old 486 (terrible machine, everything was built into the motherboard). It turned out that it was doing a low-level format which killed the IDE drive. I've never understood why Packard Bell who sold many of their computers to novices would ship something that could damage the hardware. To save face my friend just said the Windows crash had messed up the machine and I let him have one of the 40Mb hard drives I owned at the time. -- Gareth Knight Amiga Interactive Guide | ICQ No. 24185856 http://welcome.to/aig | "Shine on your star"

Cromemco Dazzler

by edick＠idcomm.com

There are supposed to be three of these board sets, though I saw one or two for the first time in 20 years yesterday. One appears to be complete with doc's and software, though the others, which I know were "played with" by my associates, may not be as complete, and some duplicating may be called for. I'm pretty certain that I can lay hands on two of these sets more or less right away, including one set of doc's and software, which I believe I held in my hands yesterday. The quandary arises out of the fact that there is at least one other board set, and i don't have a running CP/M box, since I'm not a collector. I've had a couple of modest cash offers, but would rather leave $$$ out of the equation if possible. If you have anything swappable, I'm interested in single-board computers, preferably small and simple, with documentation and firmware so I can USE them for something. If you're a Cromemco addict, you may be interested in the fact that I have a couple of functional PERSCI floppy drives, which were commonly available (though EXTREMELY expensive at the time) with the Cromemco systems back when Computerland used to sell them. These are single-sided (model 277) drives, of which one is packaged as an external unit complete with power supply, while another enclosure is in some less-than-functional state and extensively disassembled. I've recently looked at the power supply and noted that the regulator circuitry is missing. I also have parts of a third unit which is useable as parts only. What's probably more interesting is that I have the maintenance documents for these PERSCI drives. These are voice-coil-driven rather than stepping-motor-driven units, (for which provision was made on the later Western Digital floppy controllers) capable of stepping microseconds rather than milliseconds. I also have quite a few enclosures, power supplies, cardcages, motherboards, and other boards, mostly CPU's, FDC's, memory and I/O, some as yet unassembled, some under repair, some fully functional. Does this give you any suggestions? regards, Dick ---------- > From: Lawrence LeMay <lemay(a)cs.umn.edu> > To: Discussion re-collecting of classic computers <classiccmp(a)u.washington.edu> > Subject: Re: Cromemco Dazzler > Date: Saturday, February 20, 1999 9:30 AM > > [Charset ISO-8859-1 unsupported, filtering to ASCII...] > > I was digging throught the pile of "stuff" from days of old, and find I > > have a board-set (S-100) which is a Cromemco (remember them?)

Is this the same thing perhaps as a Dick Smith >VZ200? As Andrew Davie said, seems so. I have the VZ200 and VZ300 as sold by Dick Smith, and the VZ 200 manual says copyright Video Technology 1983 on the first page. To all "Oz-nerds" (as opposed to Yank-nerds or Limey-nerds?:) - in the book "Programming the Dick Smith Electronics VZ300 Personal Computer" by Tim Hartnell, there is a section on attaching a disk drive (Cat X-7302) via a floppy disk controller (X-7304) which can take two drives. You also need the 16K memory expansion (X-7306). I have the latter, but I have never laid eyes on a VZ disk drive. I assume they are rare - if you had the sort of money I expect they wanted for them in 1986-7 (the system units were still being advertised in Aust Personal Computer in June 1987 for $A169 including datacasette and 4 programs) you would have bought a better computer! The boot screen with the disk drive attached is supposed to say VIDEO TECHNOLOGY DOS BASIC V1.2 READY So has anyone ever seen that? Phil in Brisbane, Australia.

I need a ST-419 hard drive

by rigdonj＠intellistar.net

Jeff, I tried a ST-251-1 but it wouldn't work. Here's the story: I picked up a HP 9133XV drive with a bad drive in it. The XV is the one that you can partion into 4 so that it looks like 4 HP 9895 floppy drives to the system. It's the only hard drive that can be used on the HP 85, 150 and some of the others. This one has a Seagate ST-419 drive in. I replaced it with a Seagate ST-251 that has the same number of heads but more tracks and is smaller and faster. The system recognizes if but it won't format it. It says that the drives are bad. I'd like to get it running again since the XV drives are hard to find. The 251 does have fewer sectors (17 vs 32). I don't know if that's why it failed or not.

Noisy ST 251 HD

by djenner＠halcyon.com

I have a noisy ST 251 hard drive. It sounds like the bearings. Is it heretical to think I may be able to lubricate the bearings? They appear to be easily accessible on the bottom of the drive. Thanks, Dave

Dayton Hamfest

by Watzman＠ibm.net

The Dayton Hamfest is a fabulous show. It is THE LARGEST amateur radio convention [it's "official" purpose]. The Hara arena is a very good size facility, I'd guess in the over 100,000 sq. ft. range (perhaps WAY over), and it's all indoor, heated/air conditioned [not that it works with 35,000 people in the facility], and all commercial vendors, many, many of which are used computer and surplus dealers (there is lots of new stuff also). It's about 60%-70% computer, the rest general electronics and communications [radio] equipment. The flea market takes up the entire parking lot, in excess of 2,500 vendors. There are many commercial exhibits in the parking lot also, you will find a number of very large tents (10,000 square feet range each). Mendelson surplus always has a large tent, and almost every year Radio Shack [as in Tandy] collects their entire surplus and returned merchandise stuff from all over the nation and sends it all to a big tent at the Dayton Hamfest where it is sold for often ten cents on the retail dollar. However they didn't do this last year, for the first time I can remember, but they still had a huge indoor exhibit with many items, new, at 25% to 50% below normal store and catalog prices. The show is logistically difficult to attend for several reasons. First, it brings in so many people [over 25,000 plus a large local population] that poor Dayton, which is hardly a tourist mecca, is complete swamped. You can forget about finding a hotel at this point, the people who do this show get their reservations a year in advance. You may have to stay in Columbus or Cincinnati [both about 70 miles away], fortunately both are directly on an interstate highway and it's not a bad drive. The other problem is parking, since the entire lot is flea market there isn't any ! There are some LARGE fields around the complex that are used for parking, expect to pay $5 to $10 per day, and they are not paved, or very close, which become a real issue in bad weather. Then there are remote lots with busses, but that's a hassle also. The show is May 14, 15, 16. Here is an alternative, the Dayton Microcomputer association has a twice a year computer show at the same site. It's just about as large as the Hamfest, and it's ALL computer. There is no flea market, the parking lot is used for - surprise ! - PARKING ! It's almost like having 3 Dayton Hamfests a year, except that two of them don't have the flea market. This year's dates (it's only a two-day show): Spring: March 13-14 Summer/Fall: August 28-29 I plan to attend all 3 events.

There was no provision for 8" disks on the DMIII. FYI: 8" RX01 were 512blocks (256k), 8" RX02 were 1000blocks(512k) and RX50s are 800blocks (400k). So the 5.25 media is really nicer. <Forgive me, I am not familiar with DEC machines. Oh, and one more thing. <Can the screen/keyboard be replaced with a PC running a terminal emulator? <The screen is attached via a 15-pin cable but otherwise resembles a <VT-220. Thanks. No. It expects a VRR201 monitor and a LK201 or LK401 keyboard. There are two serial ports, modem and serial printer. The chances of getting those are really good around here (eastern MA) and if by may you don't have one the MIT flea is a good shot. Allison

I need a ST-419 hard drive

by jeff.kaneko＠juno.com

Hey Joe! I went down to the junkyard near where I worked, and managed to turn not one, not two, but *three* HP 9133XV's! There were also "V"'s a "D", and an "H". I grabbed one of the XV's, and plan to test it with my 9816. If the platters are in good condix, would you be interested? I could even just pull the HDD unit (14.8Mb :) and send *that* if you like!

The manual I have was a 3rd edition dated 1982, (the 2nd 1981) so he must have sold quite a few of these. The company was known as CompuKits and TMK was marketed widely in N. A. His name IIRC Was Jim Reiss. I'll have to see if he's still at my old alma mater. It's possible the one you're talking about was a later model if he joined the Uof T faculty. The built kit looked really neat. Everything was entered from the console by toggle switches or pushbuttons and it had LED indicators. It had provisions to expand memory allowing use of Motorola's MIKBUG monitor ROM to interface with a T-T or RS232 device as well as a provision to add 256 bytes of non-volatile memory. You could expand memory up to 8k x 8 static ram and suggests you use the less expensive and smaller chips like the 2102 rather than the 6810s used in RAM 1 and RAM 2. Would be an interesting project to build one, if I ever get the time. ciao larry lwalker(a)interlog.com

Call A.P.P.L.E.

by dpeschel＠u.washington.edu

I couldn't send e-mail to you. > book. Still, in my paper, Apple Worm (published in the November > 1986 issue of Call A.P.P.L.E. magazine - as the cover story), I > make reference to the book. That's a name I haven't heard in a while. What was your involvement with A.P.P.L.E.? I grew up with the Apple ][. (I mostly played games, although I wrote a few interesting programs which I may still have.) I've lived in Seattle for the past 16 years, and my family belonged to A.P.P.L.E. We didn't go to many meetings. I was the main computer user in the family, but I was much too young to drive; my mom was almost totally uninterested in computers at the time, and my dad was only slightly interested. (Admittedly, I still can't drive, because my vision is not good enough, but I think you see what I mean. And I only got one good game out of my parents, which I let them sell -- see below.) Still, at one time we had a stack of magazines, a lowercase chip for our Apple ][+, something else (came in a plastic bag with a white manual, like the lowercase chip, except the title was in yellow instead of orange... maybe related to accounting? I don't remember), The Graphics Magician (?) and its companion program, The Mummy's Curse, and assorted public-domain disks. This was all from A.P.P.L.E. I'm not nearly as Apple-centric as I used to be (for example, I now appreciate the design of the Atari and Commodore, which I basically sneered at when I was younger; and I'm experienced enough to understand the ]['s flaws). But I still feel fond about my Apples. The access to machine language is still a strong point, the disk system has an admirable design, and some of the software produced for the ][ still amazes me. And we sold the software we had and now I'm looking for some replacement items. :( -- Derek

Classic Calculator: Value?

by kyrrin＠bluefeathertech.com

Ok, so I'm not a big calculator collector. ;-) However, I did pick up a neat little box recently, one that I'd like to (a) find out, ballpark, what similar units have been going for on the swap market, and (b), use it myself for a while. What I've gotten is an HP-65, in pretty darn good shape, in its hard case with a bunch of the program pacs and all its manuals. I know I've got at least one, possibly two EE pacs, a stat pac, and others that I've not looked at just yet. The batteries are dead, of course, so I think I'd like to get them replaced at least. Are they generic NiCds or what?

[OT] Space shuttle explosions and computers (was Re: Who invented the internet?)

First off it's ok, I'm ok! <Allison wrote: <> FYI the speed attained at <> that point is some 3600mph far from orbital velocity. < <I'm not sure how to parse that. Are you saying that it was traveling at <3600 MPH, which is far from orbital velocity (i.e., a missing comma), or <that it was travelling at 3600 MPH less than orbital velocity? Sorry bout that. I do tend to be a tad graphlexic the comma should have been there. It was velocity of 3600. they need 17500+ to orbit. <(In any case, the use of the word velocity is incorrect.

It's my belief that the IBMs are high level systems management computers and they command the engine computers. The engines have their own local computers to handle their realtime needs. Same applies to several other systems. I consider spacecraft/aviation computers to be both classic and of great interest. Most are very system and mission specific thus may be nothing more than sequential controllers. Still, I'm curious. Allison

Old CDC/Magnetic Peripheral Drive on DPS6

by enigma＠sevensages.org

I have this weird drive on an old mini (Honeywell DPS6). These things have an internal fixed disk, plus, you have to put in a disk pack in them also. Well, on one of my drives, the belt that runs between the drive spindle and the motor broke. Where can I find a replacement? Manufacturer: Magnetic Peripheral Equip ID# BJ7D3-A Part # 77708003 Series Code 01 Another thing, I think the drive might be refurbished or something. On the serial number on one of them, atleast (the working drive) it has a hand-written "R" after the number. Anybody who can help me, please do. In fact, if you can help me with anything about the DPS6 or with GCOS6, I will be forever thankful. From what I've heard, GCOS6 is sort of a GCOS/Unix hybrid. Should be interesting. Also, if by chance, you know of an old Unix variant that would run on this baby, that could be nice too. I think having an old 7th edition Unix system would be nice. However, I think having GCOS6 would be really nice, too. Regards, J.S. Havard Head Geek The Seven Sages Project Regards, J.S.

Who invented the internet?

by edick＠idcomm.com

Well, if you mean the rescue I think you mean, it's actually in the Indian Ocean. That's where the Challenger went down. The fuel tank and solids (booster rockets) went down near Florida, but the Challenger went down on the far side of Africa if memory serves me. I, along with others, had the job of analyzing the potential failure modes in the engine controller in the wake of the Challenger accident. It's quite an interesting device, considering it's made of really old and simple TTL logic with plated wire memory (faster, though not much, than core of that generation). It had no stack, and therefore a different way of "calling" a subroutine, requiring you to have your program store in read/write memory. This ultimately meant that flaws masked by the redundancy of the system could become "inherited" from one mission to the next. There were other pitfalls as well.

I have a real nice HP-85 here but, have never really used it. If the belts are likely to deterioriate or fail, I wouldn't mind having an extra set. BTW: If anyone has an extra set of manuals for a HP85, I could sure use them. Of course, I'm willing to pay a _fair_ price. Are there any good on-line resources for HP85 programming and operation?

[OT] Space shuttle explosions and computers

by edick＠idcomm.com

I'm not at all certain about any of the mission details regarding the January 1986 (final) Challenger mission. I will yield to your obviously more accurate and current information. Having known that I'm gradually going soft in the head for some time, I'm not surprised or concerned that don't remember precise details about the final Challenger mission. I am quite certain, however, that the documents and schematics which were given to me as part of a FMEA/CIL team, which was a part of the NASA "shuttle-return-to-flight" mission the following fall, were relating to the Honeywell 516. These were not the main computers, of which there are several, but only the engine controllers, which are configured as redundant pairs, one for each engine. There was talk of a plan on the table at the time to replace these with something smaller and lighter, using semiconductor memory and having other features, but the one which we spent half a year studying, at great expense to the taxpayer, and which was purported to be used as that controller was definitely the Honeywell 516. Perhaps there were other more popular models of that number, but the one on the shuttles at that time were all of this type. These were NOT the main computers on the shuttle, but rather the dedicated main engine controllers. The IBM numbers to which you refer do sound to me like the main computers. Analysis of the engine controllers, however, is what our assigned task was, and that's what I remember. I don't suppose they would have had 50 or so of us working for six months on something that wasn't involved. It's conceivable, however, that there are several versions of this processor. It doesn't seem reasonable that they would have used two of a processor weighing what you attribute to the 516. 2.5 cu meters, however, is a small room, and sounds like approximately a 6' rack cabinet, or maybe even a pair. Are you perhaps including a bit of packaging hardware? What's used to control the engine is the processor. The technology is of the same vintage as the DEC PDP-8's I've seen, with hand-wired backplanes and built from ttl-msi. This one used plated wire memory, since that was a mite faster (1 us) than the core of the time(1.2 us). Let's see . . . the IBM AP-101S uses 1/40 cu Meter . . . that's a bit less than a cu. ftm 30 kg and 550 watts. . . . seems reasonable. That they later used one of its IOP's to replace the old model in use on the Challenger and other shuttles at the time seems reasonable as well. Unlike the defense industry and certainly unlike the commercial computer industry, the domain of flight hardware is controlled by "proven-reliable" hardware, so the "current" technology of the time, and the shuttle was designed in the late '60's and built in the '70's, was not the technology of choice. What's more, the engines in use in the early-mid '80's were hand-tweaked hangar queens, not some sort of production hardware. The controllers used "proven" software, which reflected all the caveats of the NASA policy of the time. It's not always the latest technology that you want on your 2-billion-dollar aircraft, but rather the most reliable that does the job.

Who invented the internet?

by edick＠idcomm.com

I guess we'll have to see what information is available on the net about that January 1986 event. I do seem to recall that the flight was about 2 minutes 10+ seconds underway when the ship hit the fan, so to speak. The entire trip into orbit only required about 8.5 minutes, so they were a fair piece of the way along. My recollection is that they were searching off Florida for the boosters, but in the Indian Ocean to recover the shuttle and the bodies. There was a lot of talk about the 8 minutes or so that it took for the shuttle to hit the water after things went bad. I could be mistaken, of course. It wouldn't be the first time . . .

Kleinrock

by nerdware＠laidbak.com

I just went to Len's homepage, and from what I can tell, based on the research and reading that I've done, the story as put forth in his bio is accurate. Licklider had forseen a worldwide (actually, galactic) network where information was accessible to anyone, anywhere. Kleinrock did describe how packet switching would work in his dissertation. Plus, the UCLA team was under his command. ARPA was under Bob Taylor (later to run PARC), but Taylor's job was to assemble the people to make it happen, and Kleinrock was one of them. If you get a chance to see the PBS series, Kleinrock is interviewed several times. You probably don't know his name because most of the guys from ARPA and PARC are unknowns. They are responsible for inventing most of today's computer technology, but other guys were much better at exploiting their inventions and assuming credit for them (not to mention anybill's name.....)

Floppy/Parallel Ports

(-: Roger, that's a very foolish thing to say on Classiccmp. For startres: An "Early" computer does _not_ mean "pre-1990". More like "pre-1960". Lots of pre-1990 machines used a parallel port to talk to floppy disk drives. HP and Commodore machines used HPIB/GPIB for example. And yes, that was the printer port on those machines too. Need I go on? Philip. :-) (I think someone else has already given a sensible answer, so I have no qualms about posting the above)

Okay, I'll try to be more clear... 8^) (And yes, I know "early" is the 50's around here. 8^) What I'm researching is computers that used the Centronics parallel port to access a floppy drive or other storage device. Mostly interested in PC's and compatibles, or computers that use a "PC-compatible" centronics port (like the Atari ST). It needs to be controlled by software only (no A/B/PRT switch like some Toshibas) and ideally needs no re-configuration before switching between drive and printer (or better still, offers a pass-through for the printer.) HP-IB/GPIB/IEEE-488 is interesting, and somewhat related, but not entirely relevant; same for SASI & SCSI. Also, anything after 1990 or so is too new.

Who invented the internet?

by edick＠idcomm.com

It's somewhat divergent from the current topic, but it might interest some to know that the Honeywell '516 is the engine control computer which was still in use on the space shuttle at the time of the Challenger accident. There were two, one redundant, for each engine, of which I believe there were three.

FWD from alt.folklore.computers

by steverob＠hotoffice.com

Found this in another news group. Please reply to the original poster not this group... <CLIP> DIGI-COMP 1 FOR SALE My wife's aunt just cleaned out her closet and gave us a digi-comp 1 in excellent shape with all the manuals, box, etc. I see from previous discussion that this is a beloved object to many of you.Since I don't want to profit on her (pre)spring cleaning, I would be happy to ship the unit to the first person who would be willing to make a $500 donation to the charity of my choosing (for a 40% bracket, that is a $300 net expense).I will be happy to confirm contents and quality of the unit with _serious_ purchasers. Since this is a charitable donation, I will not go down on the price (if no buyers emerge by March 1st, it's off to ebay). It will be sold first come, first served basis.Please, no haggling, and I hope that we can find a nice home for this little red computer, while supporting a worthy charity as well. Best regards,Lionel zuckier(a)aecom.yu.edu </CLIP> Steve Robertson - <steverob(a)hotoffice.com>

Floppy/Parallel Ports

by allisonp＠world.std.com

<In which case you're restricting it to PCs and clones only I would think. < <The PC printer port has 12 outputs and 5 inputs IIRC. But for a _printer_ <you really only need to have the 8 data lines, strobe and either ack or <busy. The others can normally be ignored. But non-printer PC parallel <port devices often use all 17 lines for whatever purpose (e.g. reading a <nybble in on 4 of the 5 inputs) The implmentationwas full centronics parallel. The extra inputs are PAPER OUT and a few other status indicators. <Before that, centronics ports tended to be the 36 pin amphenol connector. <But there were other printer port standards as well - like Data Products <that was used on some line printers. And of course serial printer ports <(RS232, current loop, etc). Commonly it was 34 or 40 pin card edge or the amphenol that we see on the back of the printer but 37 pin DB connectors were used as well. In the olden days there were two common and nearly similar parallel ports. Data Products (also used for DEC LP25/26/27) and Centronics. Allison

Anyway if they are so plentiful in Orlando how about getting me a Keyboard and a monitor for it.. <Grin>!! I still have some have some change left from the $3.50 I paid for the CPU... Phil... BTW: The Clerk at the Thrift store was convinced it was a VCR, and now that I look at it, it does look very much like a VCR.. Same size, Same color (Metal Gray / Black Front).. OK that makes it collectable Right !!!! "In the year 2525 (If man is still alive, if woman can survive) Commodore 64 computers will still be plentiful and routinely sold at Garage Sales"

M SoKit 68

by amichael＠nortelnetworks.com

I've never heard of the M(icro)SOKit 68, but I'm wondering how many other enterprising teachers designed their own small systems for training? I have a "U of T 6809" board, a teaching aid developed by the University of Toronto in the early 80s and manufactured for them by a Toronto company. At one time they were even advertised nationally in one of the Canadian hobby electronics magazines. It was a single-board system with a monitor/debugger in eprom, and you'd run it from a terminal. You could develop programs on-board, or download 6809 code from a host system and run it on the card. Does anyone else have one of these?
