Has anybody out there had recent contact with William Donzelli? I've got two e-mail addresses for him, and both bounce. And it looks like he hasn't posted anything to classiccmp for nearly a month... Bill.

Which backup program is this?

by mark_k＠iname.com

Hi, Some time ago I posted about an old Sony 650MB 5.25" MO drive that I acquired. I have now cleaned all the disks, and it seems to be working fine. Anyway, most of the disks that came with the drive contain old backups. I'm not sure which backup program was used to create the backups. I would like to find out, because hopefully then I can snoop through them more easily than having to use a disk editor. There seems to be various source code and other things on there. In the hope that someone here can point me in the right direction, here is some brief info about the backups. The backup program probably ran under OS/2. Sectors 0 to 3 inclusive contain: "MDIELS4" in ASCII 25 zero bytes a date in ASCII, e.g. "Tue Jan 12 08:48:26 1993" 0x0a, 0x00 "mondayb" in ASCII (this may be some backup ID assigned by the operator) the remainder of sectors 0-3 are all zero bytes Sector 4 begins with "MDIVOLID" in ASCII. The next significant thing is at start of sector 256: 0xEB, 0x3C, 0x90 "MDI 4.0" in ASCII. Any ideas? -- Mark

The way to build a wall is to stack them not all the same way round. The most stable method is probably LRRLLRRLL..., but LRLRLR would probably work (L and R meaning Macs facing Left and Right respectively) Philip.

core... more

by allisonp＠world.std.com

Well thanks to John D. I have a bunch of cores from the early 60s. They are roughly 50mils x 11 mils x 15mils. Cross section of the doughnut is rectangular at 15x11 mils. The reason for such rough measurements is my vernier is only good to .001" and I'd need somthing fancier to be more accurate. By eyeball the 8e cores are smaller! Based on several articles I've read theses will need about 400->600ma to switch and will do so in under 4uS. I will have to test this in a jig. Since the hole is ~20mils several #40 wires should pass through it easily. A simple core frame would be 8x8 (64 bits) and use a 4 wire system as that simplifies the select, inhibit and sense hardware. I'd likely go with late 70s level TTL and transistors to drive these and to sense the outputs I don't know if I'll use transistors (1968 or earlier designs) or comparator chips (aka 1540, 710, 711) will be used. They would also be consistant with 1970s technology. The goal if I can get the time is a 64x8 or 64x12 memory. Not large but enough. Why 64? becuase 1 of 8 decoders were common even in 1970, and the larger the array the more noise from switching. So 8x8 is manageable. Allison

I have an FTS-86 somewhere (probably mostly Honeywell with the amount of board swapping that went on) which I must get working... FTS sold this machine as "The non-compatible compatible". It was not IBM compatible. You could have 896K bytes of main memory, rather than 640. It ran Concurrent CPM, not (MS) DOS. And yet Lotus 123 would load straight of an IBM disk and draw graphs and things with no hassle... Philip.

Stuff I found at Dayton

by cfandt＠netsync.net

Here's a bit of a report of what I found at the Hamvention. I was there on Friday from about 09:15 to 17:30 except lunch for which we went off the grounds and on Saturday from about 08:00 to 13:30. Therefore with my method of checking every promising box and poking around under tables I saw about 3/4 of the whole fleamarket. I was looking for quite a variety of things -not just old computers. Stuff I dragged home were two DG Ones (model 2208A), two DG printers which go with them (model 2230), one AC power supply and one printer cable all for $15; VMEbus boards including one unopened Force Computers SYS68Y DRAM-2 memory board ($5) and four Motorola CODEX boards, $15; an IOMEGA Ditto Easy 3200 external tape drive (Travan 3) with cable and power supply, $25. And my best find of all: a virtually mint, seemingly unused HP9000/300 computer with 7958B hard drive (150 Mb IIRC) and 9144A 16-track tape drive. A label on the 98574 CPU module indicated it's been upgraded to a 375 which is just about the ultimate of the 300-series. A 68030 processor running at 50MHz and 16 Mb of RAM. Nice! I've been casually looking for one of the 300's for a couple of years. My ex-colleague who's an engineering manager from my ex-company's German parent company told me last week when he visited the house that an HP 9000/332 system was promised to me and will be shipped to me from their Chicago facility late this year. My new 9000/375 system was built into a 19" rack enclosure which was in turn bolted into a fiberglas transit case about 3' tall, 2' wide by about 2.5' deep. It was part of a military surplus system. I did not get a chance to find the AN system designation on the rack or case, just that it weighed 97 pounds and required two persons to carry. Apparently it had been built and not used *ever*. Just stuck in a military warehouse probably as a result of a military contract which didn't go anywhere or as a result of the Cold War ceasing or something. I absolutely cannot see *any* dust on the leading edges of the fan blades so this system has maybe only an hour or two at most of operation :) SNs are from mid-89. There's a Federal Stock Number or system part number rubber stamped onto the right side of the computer box. A probably earlier FSN or contractor's PN has been blacked out with paint (about 3/8" x 1.5" strip) and the present number rubber stamped onto the case after the upgrade to the 375 model was done. A little ugly, but what the hey! It shows a bit about the original purpose of the machine. That's the only indication of any special use of it. The update was done in December '91 according to a date handwritten on the CPU board tag inside. I was passing by the previous owner's space when I overheard one of the guys asking "What is it?" as they were taking the cover off the 7958B box to try and figure out just what *it* was. I looked and saw the main box was a 300 system (Whoa!! Let's stop and look!), became interested and checked it out. I offered an explanation as to what it was, what it was usually used for, typical processors used in the 300's, etc. Apparently the then-new owner who'd just dragged it to his space from a nearby surplus dealer didn't see a use for it for himself and offered the HP 9000 items to me and I paid him nearly all the remaining money I had to spend: $40 for all three boxes. He kept the transit case and 19" rack which bolted inside as he had a use for it back at home in Houston. He didn't recognize at first when he bought the whole transit case (for $50) that those 3 HP boxes which were clamped onto rack slide plates were actually a computer. He was happy somebody got it who knew what it was and could use it and he was happy to have the transit case. I love happiness :-) Only thing I had to promise him was to email him with what I found on the disk. He's a UNI* system admin and had enough UNI* machines of his own. I'm surprised he hadn't seen an HP 9000 machine before but these 300's were obsolete some time ago and he indicated he was always an Intel-based UNI* user. I've got a copy of HP-UX 7.0 on tape with the license, both still shrinkwrapped, and manual set that I've had for some time. Now I've got a machine to hang it upon! :) BTW, ver. 7.0 is near or at the end of HP-UX support for the 300's. Have BASIC-UX ver. 5.0 w/license and docs too! The keyboard and monitor were some sort of rugged, militarized things built into an operator's station. The fellow who had it never got from the surplus dealer as it obviously didn't quite interest him and maybe he didn't realize what it was. If it's what I *think* I saw an hour or so earlier at a surplus dealer's space not far away it definitelly wasn't the normal HP keyboard as it was part of some other section of the system used as the operations console and was connected via AN/MS connectors and cables. Have absolutely no idea as to the function of the whole system. If there's something on the hard disk when it comes up it may give me a good clue. But I gotta get it lit up first. So, does anybody have a very decent looking keyboard and HP-HIL k'bd cable they're willing to sell to me? Keyboard model *I think* should be a 46020 or 46021 or a 98203C. I don't know the exact differences as I have no pictures or specs. but they are mentioned in the "Peripheral Installation Guide for the HP 9000 Series 200/300", which I have had for some time, as being used with the 300-series. I'll post a separate request for a k'brd and other info in a separate msg. later today or tomorrow. Need feet for bottom of the boxes too but probably large stick-on rubber feet should be okay. I've got two old non-HP fixed frequency monitors I'll drag out of the garage and try after I get a k'bd. The video interface card is a 98547A which is not mentioned in the Periph. Inst. Guide. I saw a few DEC items: A rather lonely RL02 standing amongst a bunch of fairly new amateur gear; a VT320 and VT 420 with a few of DEC's serial cables; a couple of AUI-to-BNC translator modules for $10 each (Too much? Just right?) and little else that I could see. Bought a couple more Ethernet NICs for $10 new (Intel 8/16); 3.5-to-5.25" floppy adaptors for $1 each; 25' CAT5 cables for $3 each; "The Hard Disk Technical Guide", "The Modem Tech. Guide", and "The Network Tech. Guide" all w/CDROMs, published by Micro House, for $5 each; misc. cables and bits. Hard disks were even cheaper than I'd ever seen but had no extra bucks to spend, dang it. Also saw a pallet full (4' x 4' x 5' high) of Sun SPARC LX boxen; a Grid computer, don't know exact model as I don't know Grids, but I'd wager it was early. No model # on bottom or back. It weighed a ton it seemed, painted black. Guy wanted $30 but by then I was flat broke by then :( ; lots of C64 and C128 machines and accessories; tons of PeeCee stuff of all ages and condx; pallets full of printers and monitors; lots of IBM MicroChannel machines and boards; several HP Vectras; boxes of network stuff of varying conditions and types; boxes of shrinkwrapped software; bunches of other stuff I can't recall at the moment. Lots and lots of amateur radio gear of course. I wish I had more money to spend there dang it! Importantly, I did score a few really hard to find parts for the WWII BC-191F transmitter I'm trying to restore plus a few military connectors for some gear in the collection; also got a couple of test equipment manuals for units I have in the collection. Still wish I had more $$$ so I could get more old gear and parts! Dang. Saw a couple of antique radio collector friends from other distant parts of the country; made contacts with a couple of folks who may have parts for the BC-191 and the virtually identical BC-375 transmitters. Understand from another email list (Greenkeys) that a couple of fellow teletype collectors were there too. Not much TTY gear to be found though :( May have bumped into one of you ClassicCmp folks but we wouldn't have known each other visually. All-in-all a very good time. Free shuttle buses running frequently all day every day between the several distant parking areas (we parked free at the Salem Mall) and that made it very convenient to haul a heavy object or several bag loads back to the car :) Something for everybody there. Rain held off on Fri and Sat was really beautiful. I may go again someday as my uncle lives in nearby Xenia, OH and I have basically free room and board :) Only 360 miles from home so I don't have too much of an excuse not to go especially if after I find a decent paying job and could have extra $$ to spend. Wonder what the attendance was this year? No motel rooms available within a 75 mile or more radius. Columbus area was reported to be closest rooms. Incidentally, you locals may have noticed there's quite a different scene at Mendelson's Surplus in the past year or so. We went there to pickup a Hamvention ticket for myself and I was pleasantly surprised. New minor league baseball stadium being built across the street, an audio store just opened inside the main building, new parking lot in back of the church, a new Mendelson's outlet store next door across the new parking lot. But it apparently still has the good ol' 3rd floor full of all kinds of parts, equipment and untold amounts of obscure goodies! :-) Yes indeed, next year :) Regards, Chris -- -- Christian Fandt, Electronic/Electrical Historian Jamestown, NY USA cfandt(a)netsync.net Member of Antique Wireless Association URL: http://www.ggw.org/awa

However, the "real" paper that came with one of the units (I have one almost unused roll left) prints a much darker tone in both machines, suggesting it is more sensitive to heat than "garden variety" (presuming Costco sells garden variety) fax paper. I have yet to try more than one other brand (a roll of "panasonic" paper - lord knows who really made it) and it also prints "light." But it is entirely readable in any case. And the print heads are pretty rugged on these beasts, I wouldn't worry about hurting the printer with "unapproved" paper. Gary

Honeywell Bull

by owad＠caesarville.net

I have an opportunity to acquire a Honeywell Bull mainframe, free of charge. I don't have many details on it, but I'm told the computer is about 4x3x2 feet and supported 30 terminals. Any opinions on whether or not this is a computer worth saving, and if it is worth the space it will take up? Thanks. Tom Owad

Soviet/Russian classic computers?

by dcoward＠pressstart.com

Hi everyone, I have a friend that is leaving Wednesday for Russia and eastern Europe. She said that she could look around over there for old computers, if I could supply her with some names of computers to look for. Does anyone know the make and model of some classic soviet computers? They don't have to be just "personal" computers. Big Iron is also acceptable. So far, after a web search, the only names I have are the "TESLA" pc that someone brought to VCF 2 and "BESM-6" a mainframe from about 1965. If you can come up with other soviet/russian computers, please copy me as well as the list (so I don't have to wait for the digest) and also give some indication of size (just to help identify them). Thanks in advance, --Doug ========================================= Doug Coward Press Start Inc. Sunnyvale,CA =========================================

One guy near the Grid had a box of C-64 and C-128 parts. I didn't make an offer because I didn't want to haul them back to the car. The only interesting device there was what looked like a 64C (wedge-shaped case) with no C= logos on it and a sticker on the bottom that indicated that the case was made in South Australia. A Dick Smith special perhaps? > Wonder what the attendance was this year? No motel rooms available within a > 75 mile or more radius. Columbus area was reported to be closest rooms. I'm glad to live close enough to day-trip. Motel rooms in that part of the state book up well in advance. Attendance in years past was many thousands of people. I'm sure it's still thousands, but my impression is not as many thousands as it used to be before the spring and summer Dayton Computerfests at the same venue. *Those* are nice because all the tables are indoors and people like us bring things to sell to other people like us. (And this August, from what I hear, the Dayton Amiga club and Columbus Amiga club (AmiCON) are planning on putting on something jointly). -ethan _____________________________________________________________ Do You Yahoo!?

Yet another GRiDposting

by ds_spenc＠alcor.concordia.ca

You guys and gals are probably getting tired of my little GRiD updates, but here goes anyway... I am typing this message on the GRiDCase. So the modem works. 2400bps. I found Rob's GRiDBoard website, and from there found out that AST keeps the configuration files for a lot of old GRiDs on its website. I downloaded conf1520.exe from there. Now I have my doubts about this machine even being a GRiDCase 1520. Most of the configuration options don't work or are meaningless to this particular machine. Like the thing to set the backlighting on the display - my machine has a gas plasma display. And it seems to be telling me that my machine doesn't have a modem... so what the heck am I using right now? It did let me configure my expansion RAM from EMS to XMS... or was that the other way around? And it let me change my processor speed. But it wouldn't let me do anything with the hard disk and a whole bunch of other weird things. It's a '286 machine, magnesium alloy case, 1.44MB floppy, had a 20MB HD in it, has a 2400bps internal modem, standard PC ports, gas plasma display, two ROM sockets under a trapdoor above the keyboard... could this thing be anything other than a 1520? Note that is says "GRiDCASE 1500 Series" above the display. Now I suppose it's time to see if I can have the machine work *without* a hard drive installed. I just got a _very_ scary message about JVC drives seizing and taking HD controllers with them. (Thanks for the warning, Jason!) Of course, as the drive that was in the machine when I got it was seized up, the damage may already be done. And maybe that's why I'm still unable to access the HD. :( -- Doug Spence ds_spenc(a)alcor.concordia.ca http://alcor.concordia.ca/~ds_spenc/

Are IBM PCs classic?

by PaKing＠exchange.ml.com

Unaccustomed as I am to keeping my mouth shut, I will endeavor to weigh in on "Are IBM PCs classic?" - even though I just joined this classic computer list today. Since I just joined this "list" today I do not know what prompted "Are IBM PCs classic?". So forgive me in advance if my views have already been offered by others. "Are IBM PCs classic?" is something that I have wondered about and certainly needs to be addressed. If one is being precise, then when one says "IBM PCs" one is referring to the original IBM Personal Computer, introduced in 1981, with a 62.5 watt power supply, Type 1 or 2 motherboard, INTEL 8088 clocked at 4.77 MHz, four ROM sockets, five 8-bit expansion adapter slots, two full height diskette (floppy disk) drive bays and 16 or 64 KILO!-bytes of soldered main memory. If one is alluding, more generally, to all the, more or less, compatible machines that followed (including the IBM PC/XT), then you have thrown open the gates to such a broad spectrum of (sometimes very interesting and significant) machines that the discussion becomes cumbersome. In the interest of circumscribing the discussion, my comments are limited to just the original PC, plus any other "highly (BIOS) compatible" 8-bit bus, 4.77 MHZ PC compatible; like the original Compaq and other early examples. Now... When saying "classic", if you intend to be using standard, plain American English, then the question may be addressed as follows... The American Heritage dictionary has 6 definitions for classic adj. And they are (with my assessment): Definition #1. Of the highest rank or class. My collection has, among other things, five IBM PCs (Type 1 or Type 2) and, wonderful as they are, I would rather assign the "highest rank or class" distinction, as far as a classic digital computer goes, to the likes of machines like ENIAC, ILLIAC 4, System 360/95, Cray (1 and up), etc. My dad worked on ENIAC. Definition #2. Serving as an outstanding representative of its kind; model. If by PC it is agreed that we mean "IBM PC hardware compatible micro computer system" then I would say that the IBM PC is an "outstanding representative" of a IBM PC hardware compatible micro computer system" - having actually initially established and then continually defined this kind of computer. Definition #3. Having lasting significance or recognized worth. The demand for, and eventual numbers sold are a clear indication that the IBM PC had a "recognized worth" to a great many people. It wasn't cheap. Had it not had recognized worth, few would have sold and it would have suffered a fate like the PC Jr. Of course IBM PC is no longer made new so the recognized worth is not what it used to be. But many are still very much in use. To glimpse just one aspect of its "lasting significance" take a look at the IBM PC main memory allocation map. The fact that the PC compatible world is STILL contending with the fixed 640 KB boundary and display adapter memory map above that indicates that the significance is lasting. There are many more aspects of this. So the IBM PC has lasting significance, and still has recognized worth. Definition #4. Pertaining to ancient Greek or Roman literature or art. No, the IBM PC does not in any way pertain to these. Definition #5. Of or in accordance with established principals or methods in the arts and sciences. Yes, the IBM PC indeed uses well "established principals and methods" - in the sciences at least. Nothing very adventurous was attempted in its design. Its design was executed by the worlds mightiest computer company. That was where the "adventurous" aspect came in. IBM being IBM. It was a very adventurous thing for IBM to do. What eventually happened to the worlds mightiest computer company, as a result of their little, adventurous creation, makes a very compelling and ironic tale indeed. But as for the actual IBM PC hardware itself, It uses normal TTL and CMOS logic and has an: internal power supply, motherboard (with Intel CPU, dynamic ram memory, ROM, adapter bus), cassette I/O port! floppy disk drive(s), detached keyboard, I/O adapters (for display, serial, parallel ports), CP/M-86, P-System Pascal, DOS (CP/M inspired), Visicalc, etc. This was all very well established by others before IBM ventured in. I am not qualified to address "in accordance with established arts" part of this definition, but the case sure looks like a classic IBM design, at least to me. Definition #6. Of lasting historical or literary significance. Literary? Not. Historical? Absolutely. The IBM PC system hardware provided a very, very good (though, unfortunately, not a really, really great) foundation upon which an entire genera of useful, rapidly advancing, affordable, accessible, (and eventually quite powerful) personal computing and data processing machines have been built. And are continuing to be built, even to this day. Plus, the very existence of the IBM PC (as good or bad as you would rate the hardware for the time) directly fostered the rapid, stable development of the entire personal computer industry. This industry was not CREATED by the IBM PC. The industry was already there (Apple, S-100, TRS-80, Sinclair, etc, etc) trying to bootstrap itself into viability. But the "endorsement" of the whole concept, by IBM creating a tangible, workable platform, that would certainly not fold up due to lack of financial resources, created an environment "comfortable" enough for the wealthy to pour in their capital and for the young and adventurous to pour their very lives. So... The IBM PC is a classic? The IBM PC is a classic general purpose stored program digital computer system. The IBM PC is a classic micro computer system. The IBM PC is a classic IBM "PC compatible" computer, odd as that may sound, and in fact defines that genre. The IBM PC is a classic little computer that you can put your arms around. The IBM PC is not a classic outside of it's league. The IBM PC is not a classic big "glass house", "mainframe" computer. The IBM PC is not one kind of classic since it doesn't even have one blinking light on the front (and I really mean "blinking" as in flashing on and off). Everybody knows that you have to have lots of blinking lights to have a REAL computer. I cut my computer teeth on an IBM 360/44 (with the 200ns high speed! register option, and that little internal pancake disk drive). It took me quite awhile to get over the fascination of watching the light show dancing around on the front panel. Lights went out with the 370 mid-life kickers and things just weren't the same after that. The IBM PC is not a classic big computer - the kind that put ITS arms around YOU. And those of you who know what I mean, know what I mean. However... If by "classic" you are using some other definition (which you have every right to do) then one can not address the question without knowing the special definition that you have in mind. For example, if by "classic" it is meant that they will eventually be sought after by overly mature, as in aging, men and women looking for a way to bring back some very fond memories of a more vital, adventurous time. And willing to pay (possibly large) sums of money to get such an object of desire - so that they can brag sagely about it to their (also older) knowing friends. If that is what is meant by "classic" then... The IBM PC is not a classic - for everyone. I know of no "classic" anything that is. Will the IBM PC be a popular classic as time goes by? I don't know. But I can tell you that it has become popular with me. I'm way more overly mature than I would like to be and, ahem, I have a original IBM PC, with a Type 1 motherboard and a serial number of _235785. Top that! I am sure some of you can. I plan to de-expand it back to an earlier representative configuration - with one SINGLE SIDED diskette drive! And boot DOS 1.0 or 3.3. And if I find a Type 1 with a number __99999 or less, then I will investigate procuring that. And if I find a Type 1 with a number ___999 or less, then I will really investigate procuring that - and so forth. No I'm not a nut. But I am a collector on the look-out. I have a small (25) "PC" collection (with a cut off at the first Pentium) mostly because I can't stand to see fully functional digital computers, who did nothing but serve their masters, trashed and lost forever. I certainly don't need to find an earlier Type 1, I already have a pretty nice example. What I NEED to find is a fully functional IBM PC Expansion Chassis (with two 10 Meg disk drives) to connect to my Type 1. This could run everything from DOS 1.1 to Windows 3.0. Are IBM PCs classic? Yes, by and large they really are - though not for everyone. Now... If you know where I could get my hands on a working IBM PC Expansion Chassis, especially one headed for oblivion, please let me know. I am, Paul King at PaKing(a)exchange.ml.com

Honeywell Bull

by jlwest＠tseinc.com

Again, I don't have Honeywell knowledge, but didn't they create a division called Honeywell Bull Information Systems, and rebadged multiple systems under that name? My only knowledge of this comes from my General Automation days. When their Motorola based line was loosing market share to the Unix crowd, they introduced a server called a Honeywell Bull (blue/green nameplate I think)? That system I know for sure was an RS6000. Perhaps HBIS rebadged more than just the RS6000. Sounds like it anywho...

(fwd) WARNING! New Ebay SCAM! (fwd)

by edick＠idcomm.com

You won't find eBay wanting to "get in the middle" in that way. They get a fee based on the high bid. They don't really care whether the transaction is completed. Of course, the seller gets a credit for his fee in the case where the sale isn't completed, but eBay still gets the money. Why would they want to change this comfortable arrangement?

The PDP8 is a very elegant machine, so I can > understand wanting to own one (I have a couple...) but I can't see why > you'd pick that one model. It is the most common one, I guess... In my case the -8/e was the _last_ one I got. I'm personally fond of the pre-OMNIBUS machines (-8/L and -8/i) for the simple matter that they are made of wads of TTL and assembled in such a fashion that it's entirely possible to envision how this gate connects to that flop, etc, and trace the operation of the ALU, etc. The appeal of the OMNIBUS machines is that it's easier to hang modern devices off of them. Of course, it probably comes down to the question of "what did you encounter first". In my case, it was an -8/L followed by an -8/i followed by an -8/a. As for most common, around here, I ran across as many -8/a's as all other kinds put together (during the 1980's when such things were to be found in the wild at all). I wish I could have rescued the two -8/m's that were at OSU analyzing horse urine for the state racing commission. They had a rack of Diablo RK03's on a switch with one CPU attached to a mass spectrometer and the other CPU attached to a 9-track and a Tektronics printing terminal. It was four racks of CPUs, disks and such. The last time I saw them was 1987, give or take a year. It's where I cut my teeth on RTS-8 (during the maintenance time on the mass spec). -ethan _____________________________________________________________ Do You Yahoo!?

CURSOR and Commodore cassettes

Unfortunately I had to move on to other projects just as I was making progress. First, IMHO if you are sampling at less than 44.1, you are making things too hard on yourself. I did find the format of the header in a book and now I can't remember which book it was, but I'm fairly certain it was a PET book. I started with a test program consisting of: 10 REM ABCDEFGHIJKLMNOPQRSTUVWXYZ Then I wrote a C program to measure pulses from "bottom to bottom". Analyzing the data, I choose 15 samples as the difference between small pulse and a large one. 15 or less was small and 16 or greater was a large. > with maximum amplitude and a smaller frequency. Yes, this is a sync bit at the start of ever byte. Watching for this will tell you when the data begins. Below I have copied the begining of the last test output I ran. First there is a row of pulse lengths (in samples) (20 17 17 14 14 17 14 17 17 12 14 17 13 16 13 16 16 14 13 17) Then there is a row where zero is a "small pulse", 1 is a "large" pulse. ( 1 1 1 0 0 1 0 1 1 0 0 1 0 1 0 1 1 0 0 1 ) With that information, I determine the byte like this: * the first two pulses are 1 and 1 - this is the sync bit. * the next two pulses are the low order bit * a 1 followed by a 0 is a 1 * a 0 followed by a 1 is a 0 * and the last two pulses is the parity bit So in the first line of data: 1 1 1 0 0 1 0 1 1 0 0 1 0 1 0 1 1 0 0 1 represents hex 89. This is just a small portion of the output file. It shows the header up to and including the filename (TEST1). If you want, I can sent you the rest of this file off list. ; ; Cassette Tape Analysis of c6444812.wav Created 09/11/97 ; Silence............for 0x0024F2 bytes at byte count 0x000024F3 Reading leader.......

Are IBM PCs classic?

by edick＠idcomm.com

The only XT I still have is one based on an 80186, which I've used to develop code for the '186. The XT was, for the most part, hampered by the presence of all the PC hardware. With the '186, you could make the internal peripherals go away and reappear at a location not addressed by the PC hardware, though there were sometimes ambiguities which fouled things up.

Are IBM PCs classic?

by jlwest＠tseinc.com

I certainly have the same mindset that PC's aren't worthy of being "classic" in the sense that a PDP-8 or HP2108A is.... at first blush.... But thinking about it more, it would seem to me that like quantum mechanics, it depends on the time and act of the observation. Specifically, we might not be so quick to dismiss the PC architecture if we were currently in the year 2100 (that was just a random choice of year, nothing to do with HP's <grin>). To provide a counterpoint to that, there were so many PCs and PC clones, that collecting them would be more tantamount to collecting matchbox cars than collecting real cars (which I liken to collecting mini's). They're much easier to comeby right now, so one would collect for color and variety for example rather than each item depicting a phase of computing history. While I understand and agree with others idea that PC's are "not as historically significant except as a whole", I think it is - no less - a valid item to collect. BTW - I'm referring to PC architecture machines, not S100, or even PET type machines. Just my .00002 cents worth. Cheers! Jay West

Scientific Micro Systems

by edick＠idcomm.com

SMS was the maker of a number of 8X300-based FDC's. These were about 10x12" things with loads of TTL, normally bounted in a 17x18x15" (wxlxh) cast aluminum-framed case with a clipped-on aluminum shell, often painted off-white or beige, in which there were two 8" drives. The boards had numbers like FDC300 or FT400, and were interfaced via a req/ack handshake and 8-bit data on a 50-conductor cable. The models (300 & 400) with which I'm familiar, were single-sided, but the FDC of the 400 supported double-density. The interface protococ was at the sector or track level, i.e. it was simple and based on commands like "read the next sector" or format the next track, with much less fiddling than with the WD or NEC FDC's. Their HDC's worked more or less like the bridge controllers from other vendors. SMS was the original developer of the 8X300 microcontroller, produced for them by Signetics. They later produced FDC's and HDC's under the name OMTI. I may still have doc's for the ones I had, though I remember at least one of the manuals got a mite wet some time back.

Tossing

by edick＠idcomm.com

I can understand why people go ahead and "toss" things as opposed to going to the trouble to pack and ship them. Whereas I seldom object to giving someone who will use it an item in my storage heap, I have had qualms, at times, about people who wanted "everything" when I knew up front that it would just go from my dead storage area to theirs. I never worried so much about what happened to the puppies I sold. I guess I figured that people willing to pay for something would care for it and put it to use. What a silly notion! When I made public what I had here, I got lots of requests for essentially "all the good stuff" if there is such a designation, and at the end of the day, so to speak, only one fellow sent funds to cover shipping. I sent him the two boards he requested, and, as far as I'm concerned, he still has credit with me for another USPS priority mail shipment of <2 lbs. Of course shipping boards or diskettes/manuals is pretty easy when compared with shipping a 20" high by 30" deep metal box . . .

Oh. I got the impression that it was the highest bidder doing this, i.e. outbidding the legitimate bidders; then selling his stuff to the failed bidders; and only then backing down on the original sale. Very nasty, because the original vendor can't sell to the failed bidders until he has definitely heard that the winner is backing down... At a genuine auction in the UK, the auctioneer has the legal power to sign a contract of purchase on behalf of either party. So backing down is very, very difficult. But this sort of safeguard has yet to reach Ebay, I suppose. Philip.

I saw a photocopier demonstrated on TV well over 10 years ago which copied books without opening them more than about 80 degrees. I seem to recall it was the British Library who were sponsoring the development, but I may be confusing this with something else. Philip.

pdp 11/34 CPU - House Broken, Spayed, Likes Kids

by STSyntor＠aol.com

I have one used (What other kind could there be?) pdp 11/34 CPU and an RL 02 drive. It seems lonely sitting in my garage but I can't bring myself to send it to the local metal recycler. The system was fully operational when replaced by a "Stratus" system. It was operating as some kind of message switch. I also have a rack of "Data Comm General" 1200-9600 modems for dedicated lines. Any interest in these fine specimens? Dave stsyntor(a)aol.com "Knowledge is power but information can be sold."

Intel Extender cards

by rigdonj＠intellistar.net

Hi all, I picked up a pair of Intel extender cards in my travels and I'm wondering if anyone knows what they might be for. They have two sets of contacts with 80 contacts in each (40 per side per set). The contacts in each set have 1/10" spacing. No, they're not MultiBus :-( They have long guides built onto them to support the card being tested. Any ideas? Joe

(fwd) WARNING! New Ebay SCAM! (fwd)

by fpp＠concentric.net

>It means that the "dealer" has an item X in their inventory, they see that someone else on Ebay is selling an equivalent X. The dealer follows the auction to completion, when complete, the dealer sends email to the second highest bidder and asks if they would like to purchase the item from them for the price they offered the seller. This is a scam? Give it a break guys. If I bid on something and am not the high bidder I would like a chance to buy. If you don't then don't reply. Sometimes you can get in a bidding war and end up pay many times the value of an item, I.E. Imsai or Altec on Ebay, Is it really that different than making an offer here to someone who has something you want? So who looses if a seller contacts you and you agree on a fair price? Ebay? Time to face the facts Ebay, Yahoo, etc., etc. auctions are going to stay a while.

(fwd) WARNING! New Ebay SCAM! (fwd)

by jpl15＠netcom.com

Usually I remain aloof from e-bay stuff, as I do not use, or much like, the system. HOWEVER, this seems an easy way to get scammed by someone and does not appear to be reasonably detectable until it's too late. I have deleted identifying bits in the text to keep from propagating innocent IDs all over. Forwarded message follows: -------------------------------------------------------- Xref: ix.netcom.com rec.radio.swap I don't normally post on this group, but this is so important that it needs to get out as quickly as possible before anybody else gets burned. Late last month (April) I had put a XXXX repeater up for sale on Ebay. It was bid on by quite a few different persons. The high bidder on it didn't contact me for four days and finally sent an email backing out of the deal. This resulted in a negative feedback being placed which made it public knowledge that he had back out. Two days ago I was contacted by two of the higher bidders. Each had been contacted by a person in Xxxxxx Xxxxx, California wanting to know if they were still willing to honor their bid on the repeater! Now this is the very same repeater sitting in my shop as I type this! Since the email address of the seller in the original auction was overlooked (you would have to do a search of past auctions to get a peek at it) this person played the part very well as the owner and managed to get two money orders sent to him. The address he uses is a mail drop on XXXXX Rd in Xxxxx Xxxxxx, CA. If you see this street come up in any dealings with a person out in that area BEWARE! PLEASE if you have been or get contacted by anybody on Ebay who wants to pursue a bid you made on an item, double check his email address >from the original auction page. Ebay has been notified and I'm pushing to get the bidding history either removed or modified to notify all involved that the history has been accessed. Thank you for taking the time to read. Signed XXXXXXXXX ---------------------------------------------------------- End forwarded message Since we here are dealing in a different line of equipment, I did not include the alleged miscreant's address or city... but the algorithm of the scam can be applied anywhere. Of course I realize that anyone can post anything they like to Usenet, but this has the Ring of Truth to it. Caveat Vendor..... just another reason I dislike e-bay. No *real* auction is timed... the sale is made final when no other bidder increments the price... so even 'sniping' has a balancing force against it: the ever-rising price. When there is a known time limit for the sale to expire, then how can that be fair? Cheers John

It was OK to make a couple of shirts from transfer paper, but it's quite time consuming to print out the sheet, trim the edges, iron the shirt and backing pillowcase, then apply the image. If I owned the image, I'd consider it, but the image that I liked the best was the photo of someone's personal machine; they own the copyright, but were nice enough to let me use the image for my own purposes. -ethan _____________________________________________________________ Do You Yahoo!?

good source of obscure IBM parts?

by red＠bears.org

As the new owner of an abandoned IBM product (Thinkpad Power Series 850, 1995, not on topic, though highly advanced at the time and now abandoned) I was wondering if anybody had any favourite IBM remarketers they turned to when in need of IBM unobtanium, or were chummy with any warehouse managers... I'm willing to throw money at this one, it's too close to being Really Cool to not. (: For those unfamiliar with the Thinkpad Power Series line, they are IBM's brief foray into the RS/6000 laptop market. The 850 sports a 100 MHz PPC 603e (not speedy) and a surprising array of multimedia capabilities (including NTSC video I/O), and runs AIX up to 4.1.5, or 4.2.something if one feels lucky. I'd appreciate any leads anybody could pass on. ok r.

OT - Rantish, but a warning

by jim＠calico.litterbox.com

Way off topic here, and rantish to boot, but just to give y'all a heads up - Don't install Internet Explorer 5. Bunches of reasons, but my big one is this: If you are ill advised enough to uninstall explorer 4, you *can't* get 5 off your system. And at least when I tried it has destabilized my system to the point my desktop crashes about every 10 minutes. I'll be migrating to BeOS as soon as they mail my copy to me. *grumble* On the other hand, and considerably more on topic, the new hobbiest media for openVMS is supposedly going to be available on the 18th of this month from http://www.montagar.com/hobbyist/media.html. -- Jim Strickland jim(a)DIESPAMMERSCUMcalico.litterbox.com ----------------------------------------------------------------------- Vote Meadocrat!

Australia: 8080A chips, eproms, dynamic rams, i/o chips, data books

by davhos＠magna.com.au

I have four 8080 computer systems to dispose of. They were used in a dedicated industrial application - not as a readily reprogrammable system. Some of the chips may however be of use to someone - preferably someone who can collect from Chatswood, Sydney Australia. The main chips are (I am only listing chips in sockets) 4 off 8080A about 200 dynamic memory chips. some are marked 4030, others 4060. they are also referred to as 2107B-4 in the documentation. about 25 eproms type 1702A about 12 off 8212 i/o port chips about 30 off chips marked SN74S412. I cannot find this in my old data book but from the circuit they appear to be doing the same job as 8212 Also available are Intel data catalogues from 1976 and 1977 and a Signetics Bipolar and Mos memory databook dated 1977 David

IE: net or local boot, local swap everything else from the net host. Then the seap drive can be a small 20-40mb drive and the swapping is faster if local even with PIO. that would yeild a fairly fast system that wouldn't beat teh disks to death on the host. Allison

Altair, pfeh! I own a Univac.

by yakowenk＠cs.unc.edu

Well, okay, parts of one. Big parts. For now it is in storage. Guess I have to get a basement next. I'm not even sure exactly what I've got. It is from a Univac 9200. Looks like a line printer and control console in one very big box, about the size of desk, but maybe twice as tall. Switches & lights, and discrete transistors. It was the box that had the "Univac 9200" label on it, so maybe (hopefully) it is the CPU. When I move it >from its current temporary home to a more permanent one, I'll get pix & details. There is another box that I didn't get, but may still end up with after its winner picks a few bits out of it. Seems _he_ actually has customers still running these things, and needs a few specific parts. So even if I get it, it won't be complete. But I can't complain, with those parts going to keep another Univac running. Also got a card punch, which I got home by partially disassembling it, to make it fit in my car. When I opened it up, I found a three ring binder labelled "Univac Servicing Documents" - schematics, mech drawings, all sorts of good stuff! So, anybody know anything about 9200's? A web search didn't turn up much. Introduced in June 1967, 8K of memory, that's about it. Bill. (Man, this is awesome!)

Dayton Hamvention report

As has already been mentioned, Dayton is _not_ the place to go to look for used DEC parts. I only spotted a couple of table-top uVAXen. I did get a Kaypro 2 for $25 (and the kid dragged to my car!), a $2 VIC-20 with $1 C2N and some modern stuff. I didn't spend anywhere near as much as I usually do. Not all that many things lept out at me. There were scads of $5 and $10 Pentium boards, crates of ISA NICs and lots of stuff that just isn't all that interesting. I did make the T-shirts, one from the photo of a working PDP-8/e and one >from the scan of the marketing literature.

Acorn RiscPC 600 (OT - only 5 years old)

It has a label identifying it as "Adapter/Eliminator" or similar. They're *very* rare, partly because Acorn tried to recall them, and partly because not many were sent out before the problem was spotted. There's one fairly common one, which *isn't* particularly prone to go "phut", and that's probably what you have. The only thing wrong with that one is that it doesn't have much spare capacity, and therefore has no connector for a disk (or w.h.y.). -- Pete Peter Turnbull Dept. of Computer Science University of York

sun mice

You will know that you've reached the bone-us level when you have in front of you a type 3 mouse with the pins in its RJ-11 plug and a type 3 keyboard with a standard RJ-11 jack that won't accept the pins. I have a type 2 mouse here. It's black with gray buttons, and has a Sun sticker on top with the purple, on-its-corner Sun logo and black "sun" text. On bottom there's a Mouse Systems label with the following dot-matrix imprint: MSC 900783-002/01 SN MSC BQ00226 MADE IN USA Type 2: keyboard and mouse both have RJ-11 plugs The 2/120 can have RJ-11 jacks for this combination; both devices get plugged separately into the CPU cabinet (but I think the connectors go to the bwtwo or other framebuffer). Type 3: keyboard has RJ-11 jack for mouse and DA15 plug to system; mouse daisy-chains through keyboard The 2/50, 3/50, 3/60, and I guess most Sun 3s excepting the 3/80 use this DA15 connector. The 2/50 came with an adaptor box that plugged into the DA15 socket on the back of the CPU and brought out two RJ-11 jacks. The adaptor box works on Sun 3s too. Type 4: keyboard has mini-DIN plug and socket(s) for mouse; mouse daisy-chains through keyboard There's also an adaptor box that plugs into the DA15 socket that brings out a mini-DIN socket so you can use a Type 4 keyboard and mouse on your Sun 3 -- I guess Sun ran out of Type 3 keyboards before the service life ended or something. Or maybe people with Sun 3s just wanted to use Type 4 keyboards? (Ewww, but then I don't like the Type 4 keyboard.) Somewhere along the way (I think midstream Type 4, or maybe when the Type 5 keyboard was introduced?) the mice changed to a high-resolution flavor with a denser grid on the optical mouse pad. Predictably, old and new mice and pads don't work with each other. -Frank McConnell

IBM 286 Help Request

by snegri＠azstarnet.com

A friend gave me his old IBM 286 which I'd like to revive for my wife's use. When I power on, a red light indicates the machine is looking at the 5.25 floppy drive, then I hear two beeps, and nothing at all appears on the screen. I'm thinking that maybe the BIOS somehow got trashed but I don't have a clue what to do about it. I don't think there's anything wrong with the monitor. I think the computer just doesn't seem to know it has a hard drive and monitor connected. Any advice would be sincerely appreciated. I tried removing and reseating all the cards because that's sometimes solved problems when I had my own 286, but it didn't do any good with this machine. Thanks in advance.

Tiara Arcnet LANCard AT??

Size, weight of a PDP-11/83?

by gregorym＠cadvision.com

Hi all. Through a lovely bit of serendipity, I've just been offered a PDP-11/83 that's local to me. Before I accept, can anyone help me with the following questions: How big is this classic likely to be? Most PDPs I've seen were refridgerator sized, with washing machine sized disk drives, tape drives, etc. Is that about what I can expect, or is the 11/83 one of the later, smaller 11s? How heavy might it be? Would it be a lifting job for 2? 4? 8? Does it require special power? My home isn't wired for anything beyond household current. Any help would be much appreciated. I'd love to save this machine, but there are limits to my space/money/housemate's patience. Alternatively, if anyone else is in or around Calgary, AB, and would be interested in this machine, e-mail me off list. If I decide not to take it, I can put you in touch with the owner. Thanks in advance.

Of the microprocessor version of the PDP-11 (11/03, 11/23, 11/53, 11/73, 11/83 and the 11/93) it's one of the faster ones and a good catch.

It can run RT-11, RSTS, RSX-11 and most of the *nix versions with 2.11 being a good fit. The PUPs list (pups(a)minnie.adfa.oz.au) can set you up with a license for all PDP-11 unix for 100$ and also has an archive. Allison

PDP-8/e frontpanel pictures

by cmcmanis＠mcmanis.com

Hi Ethan, Good luck, I've scoured the Flea Market twice (once on Friday and once today) and there just ain't any DEC stuff here. One guy had a box of Q-bus boards with a uVAX-II CPU plus some 8MB memory boards. If I had need of them they might have been a deal at $10/each. And the guts of an 11/34a. Neither looked like it has been treated well. I did find a PDP-8 core stack but it was in a display case at my friends office where we got some free tickets (sigh.) I did pick up some Nifty LCDs though for $7 that I'm going to use to create a "disk bay console" ala the Linux stuff. --Chuck

IBM PCs

by mbg＠world.std.com

About a week or so ago, I asked about IBM PCs... I had received a few when we saved the decsystem-10s (they had been used as consoles). I wasn't sure what they were (and hadn't really looked at their model numbers) and asked how I might identify IBM PCs... I got lots of good info... and today (while cleaning the museum, er, my apartment) I put them together and powered them up. They both work... One is a 5160, one is a 5150. The 5160 has what I think is a 10Mbyte hard drive and a full height 5.25" floppy. The 5150 has again a 10Mbyte hard drive and a half height 5.25" floppy. Are the floppies what account for the difference betweeen the 5160 and the 5150, or is there something else? Otherwise the monitors, keyboards and units work fine... I think I may put one up on ebay... L@@K!!

sun mice

by lemay＠cs.umn.edu

Is there a sure-fire way to determine if a sun mouse is a type 2 versis type 3? It looks like the mice for type 3 have little side-pins on the connector, so is it reasonable to assume that mice without this feature are for sun-2 series computers? I figured i'd go through the box of old sun mice at work, since they are all so old as to predate any hardware we still have in operation. Looks like there are quite a few sun3 mice, possibly a few sun 2. -Lawrence LeMay

HP-HIL mice (and some questions)

Hi! does anyone have any HP-HIL mice? I recently got a keyboard for my Vectra RS/25c, but now I need a mouse for it. Anyone know what drivers I can use for it? Also - are there any drivers for the [HP-HIL] keyboard? There's some keys on it that don't appear to do anything (such as "reset" and "menu"). There's also some blank (programmable?) keys. When I boot, it says "keyboard connector not functioning" I'm assuming this is the 5-pin DIN AT connector, but when I hook a keyboard up to it, it won't function correctly (F-keys and number pad won't work). The HP-HIL keyboard works fine, but I get the error. ThAnX, ///--->>> -Jason Willgruber (roblwill(a)usaor.net) ICQ#: 1730318 <http://members.tripod.com/general_1>

GRiDCASE 1520 back together

by ds_spenc＠alcor.concordia.ca

The GRiDCASE 1520 is back together. I think it was easier to reassemble than to disassemble. Condition: exactly the same as when I started, but with a little less black paint (from where I used a screwdriver to try to pry the case apart). I even left the battery in there. Hard drive's still not spinning up, clock is still not set. Oh, and the Compass still has a crazy clock, too. -- Doug Spence ds_spenc(a)alcor.concordia.ca http://alcor.concordia.ca/~ds_spenc/

Compass clock?

by ds_spenc＠alcor.concordia.ca

Hi, When I was using the GRiD Compass yesterday, I noticed that the system clock was frozen at 17-Nov-1985, 9:01 p.m. I tried setting it for 14-May-1999, 9:46 a.m. I thought it would b frozen again at that time, but when I powered the beast up again to make this call I was surprised to see that the clock had advanced to 9:56 a.m.! :) And instead of the 15th, it says it is the 25th! Is this an early Y2K problem? :) Is there an evil battery inside, about to leak all over my precious bubble memory modules? Oh, and BTW, how much bubble memory am I supposed to have? Currently it has "334 in use, 52 free". That's 386 units. It says "Usage (in 1000s of characters)" beneath the system memory report (I can look at these things from inside GRiDVT100, luckily) but I'm not sure if it applies to bubble memory as well as normal system memory. After all, the bubble memory is where the filesystem lives, which is a bit different. My system mem is currently "System: 153 Application: 51 Data: 18 Free: 40". That's 262,000, which is about 256 when divided by 1024. Is GRiD-OS eating most of my memory? What a hog! ;) I found the little blurb in Popular Science, August 1982, p.42, and it says that the machine comes with 256K each of bubble and normal memory. And for $8000. Was there an expensive option to get more bubble memory? Or is that what differentiates the 1100 from the 1101? Oh yeah, where is the OS stored? And applications like GRiDWrite and GRiDVT100? The VT100 emulator seems to load slowly enough, which implies that it's in bubble. So, like, if I reformat my bubble memory, I'm toast, right? I would very much like to have some sort of backup of everything in bubble memory. I don't seem to have XMODEM or any other transfer protocols on this thing. Argh. -- Doug Spence ds_spenc(a)alcor.concordia.ca http://alcor.concordia.ca/~ds_spenc/

I must remember to engage brain before putting keyboard in gear ;-) Especially when short of sleep. I've worked on literally hundreds if not thousands of the things, so I should have remembered a bit better! > I know that darn linear PSU.

If you draw too much from one connector, on Issue 3 or earlier PCBs, you can end up with a significant voltage drop. It's OK on later ones. -- Pete Peter Turnbull Dept. of Computer Science University of York

Semi-OT: MacOS 8.5-8.6 and Sherlock

by healyzh＠aracnet.com

This is mainly off topic, but deals with some interesting ways to find info on the Internet. Plus I've got some cool classic computer related links. After sitting at MacOS 8.1 on my PowerMac for around a year, thanks to 8.5 causeing some problems for me when I tried to upgrade when it came out (these problems haven't been an issue since December), I went ahead and went straight to MacOS 8.6 last night. I've been hearing about this great new search tool that was introduced in MacOS 8.5 and has been updated in 8.6. Last night briefly I gave it a try and was impressed, so this morning while working on my morning pot of coffee, I've been playing with it. I used PDP-11/44 as the seed, and have dug up some really cool classic computer related stuff. If you get a chance to try it out, I'd recommend running a few searches on computers that you're interested in. Here are a couple interesting links. http://www.tec.puv.fi/~s99137/index1.html An interesting page of old computers, including a PDP-11/44. This page led me to the next link. http://www.tuxedo.org/~esr/retro/ is "The Retrocomputing Museum", at first I thought it was one of the listmembers pages, and then I found out it's maintained by Eric S. Raymond (yes, of Open Source fame), and someone else. http://www.vaxarchive.org/compmus/kees/garage.html http://www.vaxarchive.org/hw/index.html Nice page of links about VAX Hardware http://www.telnet.hu/hamster/dr/ Akos Varga has been busy it looks like! http://www.telnet.hu/hamster/dr/ka630.html Didn't someone recently want info on the KA630 this page looks worth a look! Or for the KA650 http://www.telnet.hu/hamster/dr/ka650.html OK, I'm done wasting everyones time, please forgive my enthusiasm for something new and cool from Apple that is a cool way to find Classic Computer stuff. Oh, and yes, I realize there is probably some web site out there that will give you simular capabilities. Zane | Zane H.

Upcoming Haul: DEC Gear and Documentation

by mcquiggi＠sfu.ca

Hi Gang: I learned recently of a number of pdp-11s and Vaxen going surplus in the Vancouver area. Looks like various LSI 11s, spare parts, boards, docs. Peripherals include 9 track and (likely) DAT tape, RD53 and RD54 drives, some SMD drives. Vaxes are of the Microvax III type. Full set of VMS docs, version 4.x. Also an optical disk drive, unknown make/model, WORM type, about 18" platters. A total of about 4-5 systems. More info will be posted as I get it. Kevin --- Kevin McQuiggin VE7ZD mcquiggi(a)sfu.ca

Acorn RiscPC 600 (OT - only 5 years old)

It's a pity some dealers were not inclined to be more forthcoming, because Acorn did make a lot of documentation available, and would often provide it to users who wrote in; but dealers were always able to get it for customers, and even had a system (SID) to obtain lots of information, upgrade software, etc, via dial-up. They also had a large 2-volume set of 2" ring binders with diagrams, info, etc (that's where those System diagrams I gave you came from). -- Pete Peter Turnbull Dept. of Computer Science University of York
