But, there isn't too much traffic on this list about PC hardware, and that's not going to grow as the PC market share declines (it can hardly increase). And the thing is, as you say, little can be done for PC hardware. If it's dead, it's dead. > Personally, I'd include the IBM PC (5150) and maybe the XT (5160), > portable (5155) and AT (5170).

'Classic' carries some connotation of class or of being nostalgic, etc. Hardly any PC clones do that. Also, a generic ISA machine is hardly a collectible item, so, again, I doubt they will generate much traffic as time goes on.

FA: Panasonic 200U. Be the first on your block!

by manney＠hmcltd.net

Panasonic 200U with 32K memory, Instruction book, box (pretty beat up). Nothing happens on the screen when it's turned on, and beeps each time a key is pressed. The unit is on fine shape (cosmetically), though. It;s a flat CoCo-looking thing, with rubber chicklet keys. I can send a pic to anyone interested. Following the current practice, I guess I'll ask $8,500 on eBay, but I thought I'd offer it for a discount (say, $8,499.95) to the group. Anyone interested for the price of shipping and a few bucks? manney(a)hmcltd.net (please note address change)

OT: Need info on a PCI board

by mbg＠world.std.com

Yes, I know, this is way off-topic, but the board I recently obtained is unique... I was hoping someone on this list might be able to give me an off-line pointer to info... I obtained a PCI board produced by Evans and Sutherland which is labelled 'RealImage 1000' and appears to be VGA compatible. In an Alpha 600au, it identifies as Eclipse 4D30T... it has an angled slot for a DIMM module, and I know the board comes in 20 Mb and 32 Mb configurations. I apparently supports (or is supported by) OpenGL... I'd like to get as much bits 'n bytes (tm) level programming info on this board, as well as information on what sort of DIMM I need. The 32 Mb Dimm I have doesn't look anything like the one I see in a picture of the board, so maybe some of the 32 Mb is already on-board. Anyway, anyone with any information on this board, please contact me, I'd like to see if I can get it running on my Linux box. Thanks in advance...

It was an 80-track drive, but the disk was formatted to 40 tracks originally -- there just happened to be two sets of 40 on one of the sides. The second set was probably recorded on a double-stepped 80-track drive, so the track width was only half as wide as a real 40-track would have written, and becuse of the offset between upper and lower heads, just happened to fall in the right place. It would be an awfully complicated way to get 80 tracks out of an 80 track drive :-) -- Pete Peter Turnbull Dept. of Computer Science University of York

2002 (was:: Looking for pointers to old Control Data software)

by Jgzabol＠aol.com

Hello Hans, you are certainly welcome to it - after all its only bits and not a single atom, so it can be copied easily. However, there is no documentation apart from source code comments - it's a (hopefully) portable C program plus some ASCII data files, so it should run on anything that has a C-compiler. Since your address makes me believe that you are affiliated with Siemens Munich, and since I live in Munich too, maybe we just get together and discuss this ? I will send you my coordinates in private email. The simulator maps core and drum to RAM arrays, papertape input and output to File I/O, and the console to keyboard/screen. It would be neat to interface to a real S2002 console - there are at least two in Munich, one at the Siemens museum and one at the Deutsche Museum; maybe that would be a fun project to try one of these to agree to that proposal ????? The compiler I have is in fact the Alcor Triplex Main S2002, the result of a thesis (not mine) done at Mainz University in 1968, extending Algol by the data type TRIPLEX which is an interval representation of a floating-point number: [lower-bound, standard-f.p., upper-bound] Any operation on triplex numbers will produce the min/max values resulting >from possible roundoff, so that the error propagation of roundoff may be studied. This is theoretically nice, but in practice you can invert a 10x10 matrix only if you are lucky and it is conditioned extremely well, otherwise some pivot interval will include 0 resulting in a divide error. In those days there were fears that one could not do any calculation involving millions of f.p. operations because of roundoff - that turned out to be really academic. John G. Zabolitzky

FS: Add-in 2 Serial/2 Parallel cards

by rhblake＠bigfoot.com

I have a bunch of DFI serial/parallel adapters for sale for $7.50 each ($20 for 3) plus shipping, with docs. They have the Winbond chipset that includes 16550 UARTS and gives you 2 serial and 2 parallel ports. Better than an A/B switch if you run more than one printer, or great if you have a parllel port device like scanner. No more worry about conflicts. Works great under DOS through Win98. I have one in everyone of my 8 bit and 16 bit machines and one in my EISA server. This one is excess and needs a good home Totally setable to whatever you need. The docs (if you want to look at them) are available in PDF format at ftp://ftp.dfiusa.com/multi_io_cards/DIO222/d220830.pdf Full spcifications are shown. Includes 2 9 pin serial and 2 25 pinprinter ports, one of each on the card and one of each on an addtional slot filler, but you can move these to case openings if you desire. Shipping is minmal, probably $3.25 for a couple of them. Also have a couple Intel (and other brands) 14,400 baud internal faxmodems. Windows 95 and 98 see them fine and they work great with Win 3.1 and DOS too. All clean and in great shape. $6 each or 3 for $15 plus shipping. Again, a light item. These work great for someone with an occasional need for internet, send/recv faxes or to use free email or call BBS systems.. These items are for sale to US and APO/FPO addresses only. Shipping to other countries is not cost effective and is a real pain in many cases. I use USPS parcel post, insured unless priority is real close to the same price. Drop me a direct email if interested. Payment by money order only. Ships the same or next day as payment is recieved. These are items I have picked up for other projects and ended up with way too many, these are not connected with a business and are personal sales.

Well, hearing an error on an audio CD might be difficult. If cost is no object, you could have the data pressed to a mastered CD, as opposed to burning a CD-R at home. The "real" aluminum mastering process entails a "glass master" that might last longer than the aluminum foil version.

I personally *hate* e-bay for No Good Reason, and choose not to participate... not the least Bad Reason of which is my own financial health. I buy enough Stuff via the Net as it is. But that's just Me. Philsophically... E-bay is Capitalistic and Darwinistic. One can rail against the concept or embrace it. C'est la Vie. I spent some years in the Electronic/Aerospace surplus business, and I have been in thousands of auctions of every type. It's like This: Ya win some, an' Ya lose some. I know exactly, precisely how it is to have counted every penny one has to put on something Really Really desireable, only to be outdone at the last moment by some schmuck with deeper pockets. And of course, I've been that schmuck, too. E-bay is a 'public' forum, ie. access is not restricted. This is a 'private' list (sorta), and is (lightly) regulated; I am violating those regs right now. What the crux of Dougs' and Marvin's contretemps [where's all this Francais coming from...?] is the Morality of providing a 'heads-up' to this List of an item on e-bay which might be of interest to one or more listmembers. My tuppence: If I find a nice juicy PDP-11 system for sale, I will either buy it myself, and crow about it here afterwards, or pass on it and announce it here for others to consider. Then, IMHO, the same situation obtains: someone will be successful and the others will be dissappointed. C'est la Vie X2. I see no difference if the Item is languishing on a lonely loading dock or represented on a public auction forum. Private Note to Doug and Marv: Could you please patch this up prior to TRW Saturday (the 30th)??? I'm buying lunch for everyone in the group (after the T-hunt) and I'd like to eat peacefully... ----> ;} <----- Cheerz John

catch of the day & CPM disk format

by rigdonj＠intellistar.net

I found a box of old computer stuff today. I didn't think it was much till I cleaned it up and looked at it. Boy, appearances can be deceiving! Here's what I got: Qume Sprint 9/45 and 9/55 terminal service manual, operator's instruction manual and intefacing information. THREE BRAND NEW WordStar 3.0 packages with disks and manuals in the original MicroPro binders. THREE BRAND NEW SuperSort 1.6 packages with disks and manuals in the original MicroPro binders. One BRAND NEW CalcStar 1.2 package with disk and manual in the original MicroPro binder. THREE BRAND NEW SpellStar 1.2 packages with disks and manuals in the original plastic bag from MicroPro. THREE BRAND NEW MailMerge 3.0 packages with disks and manuals in the original plastic bag from MicroPro. One brand new package of WorkSheet Wizard with disk and manual in the original plastic bag. The docs for this one state that it's for a North Star Advantage. The manuals HINT that all of this is for a CPM system. All the disks are hard sectored 5 1/4" disk with 11 index/sector holes. Q: What system other than North Star used hard sectored 10 sector disks? Joe

Is again re: PDP-8 on e-bay

by joe＠barrera.org

>I hate to bring this up again, but has anyone seen the present bid compared to the >start bid, and where the high bidder is from, Association for Computing Machinery >(acm.org)?? I must have missed the original thread on this but it seems a bit high >for a :kind of beat up and working condition unknown" machine. How "rare" are the >PDP-8's Seems I see a lot of traffic about them here, they can't be *that* rare. I'm joebar(a)acm.org. I know, I'm stupid, but it was just sort of an impulse kind of thing. I don't know what the start bid was, but I just somehow entered a bid a little higher than the reserve. I was thinking, "how much did I spend last year on that dumb P5-166 box", and used that as a figure, given that the PDP-8 undoubtably has greater long term value than the P5-166.

Heath H/Z 19 terminals

by Watzman＠ibm.net

The keyboard encoder in the Heath H-19 terminals (also the Zenith Z-19) was a National Semiconductor part. It was discontinued in late 1981 or 82, while the terminal was still in production. Heath bought tens of thousands of them in a "last time buy" both for ongoing production and for future service. I don't know the current availability of this item from Heath (Heath does still exist, and does sell SOME parts), but it hasn't been available from National for a decade and a half. It WAS a generic part at the time. Note that every H/Z - 89/90 has an imbedded H/Z-19 terminal and therefore uses this part. I'm not sure of this, but I think that the ROM was required because the encoder only generated a "key number" and not ASCII, and it wasn't easily possible to arrange the keys for the key number to correspond to the ASCII value (Carl Goy was the designer, and he's still around out in California somewhere, he worked for Mouse Systems and Headland Technology after leaving Heath). I know all of this because for 5 years I was the Product Line Director for the entire Heath/Zenith computer line. Barry Watzman

OT: Alien Media (was Disasters and Recovery)

by Philip.Belben＠pgen.com

> It was thus said that the Great Philip.Belben(a)pgen.com once stated: >> >> I'd like to define it in terms of SI units, but the Kilogram is not too >> easy (yet). > > Really? The meter is defined (certain frequency of light from a certain > element for so many waves yada yada). Sea level is defined (don't know the > SI unit, but 780 millibars of pressure). Celcius is defined (0 is freezing > point of pure water at sea level, 100 boiling point of pure water at sea > level) and that's all you need to define the gram: one cubic centimeter of > water at 4C at sea level. That also gets you volume (liters). Well, sort of. The definition of a metre is actually 1/299792458 of the distance travelled by light in vacuo in one second. Wavelengths of the orange-red line in the spectrum of Krypton-86 went out long enough ago to qualify for this list at least! The definition of the kilogram is _still_ afaik "the mass of the international prototype kilogram" (or kilogramme, I suppose). And FWIW sea level pressure is 1013 millibars. 760 millimetres of mercury. But kilogram = mass of 1 cubic decimetre of pure water is probably accurate enough for most purposes as long as you don't have too much deuterium or oxygen-18. BTW Celsius isn't an SI unit. SI unit of temperature is the [degree] Kelvin (K, written without the degree sign), defined as 1/273.16 of the absolute temperature of the triple point of, oh no! It's water again! Again, specify hydrogen-1 and oxygen-16 and it's probably accurate enough... See. Not as easy as it sounds, but still possible. If you allow non-SI definitions, start with: Second = 1/86400 mean solar day (that changes only by a couple of percent every million years - enough that dinosaurs had a 400 day year, and ancient Babylonians observed eclipses a few tens of miles from where modern astronomers predicted them or at the wrong time of day) Metre = 1/40000000 circumference of Earth. Originally 1E-7 distance from N Pole to Equator through (I think) Paris. (Longer than SI metre by 0.02%) Then proceed as above with Celsius and volumes of water... Philip.

Looking for pointers to old Control Data software

Gary Oliver wrote: > Does anyone on this list have pointers to old Control Data software, > specifically 7 track tapes (yes I can read these) and possibly > documentation (though I do have many of the old user manuals.) > I've tried contacting the lastest version of CDC and they offer no help > whatsoever. My guess is that Control Data Systems doesn't have any 3600 software, anyway. When I worked there in the 1980's, there were no 3600 systems left in the building (although the prototype 7600 was still on the test floor). It's also been a long time since they were supporting any 3600 customers. There might be some software in a corporate archive someplace, but Ceridian is as likely to have ended up with it as Control Data Systems. In either case, they'd probably only pull something from the archive if it was for company purposes. You might have better luck with universities that had 3600 machines. Michigan State was one of them; email me privately and I'll pass on a contact there. Purdue and Northwestern are other possibilities. Re reading old tapes, the following is hearsay, but it sounds plausible to me. Old tapes have a tendency to shed bits of oxide. If that oxide lodges on the heads or tape guides, and if the tape speed is high, friction may generate enough heat to permanently damage the tape and also the heads. Thus, it is prudent to carefully clean the tape before trying to read it. ---- John Dykstra jdykstra(a)nortelnetworks.com Principal Software Architect voice: +1 651 415-1604 Nortel Networks fax: +1 612 932-8549

RS-6000 external cables, new - no second mrtgage req'd

by rhblake＠bigfoot.com

Dalco has RS-6000 cables that have the IBM mini 60 centronics to an SCSI 50 centronics now for $18.50 instead of the usual $45 each or more. You can see the item at http://www.dalco.com/cgi-bin/nph-tame.exe/dalco/conpin.tam?cart=99A20yke.ha… or use the search and search for item 57520. My understanding is that they are a slight backorder though, but worth the wait if you want to use that PS/2 with external SCSI units. I may actually get my 8595/XP server online again, this time with my cdroms.

PDP-8 on e-bay

by dogas＠leading.net

<rant> Ok, maybe its just me. I'm a conniving, sniviling, wheez who would probably step on my own mother to get at a cool computer (on my good days) and I spend alot of time raking though the ebayish trash to come across something tastey in a dark passed over corner of the sale. And just when you think you got a line on something, some damn smaraitan decides to post a billboard.... (no offense) </rant> I certainly don't mind those posts when they fall into the context of a discussion somewhat beyond 'Hey, everyone look...' I can understand publishing/reflecting a sale post that didn't come from public arena like ebay but I think anyone interested is capable of investing their own time searching for the things they want to aquire from that venue.

Looking for pointers to old Control Data software

by Jgzabol＠aol.com

Dear Gary: This is marvellous! I used to work quite a bit on a 3600 in 1968, and it is good to hear that there is some form of revitalization for that machine. Unfortunately I have not retained any software from that time, so that I cannot help you there. However, I would be very interested in hearing any information about the simulator you wrote. Is there / will there be a report on that project somewhere ? Could you send any description ? How do you simulate the console ? What do you do in hardware / in software ?? Interested in swapping ? I wrote a simulator for a Siemens S 2002, and I have a copy of the Algol compiler that went with that machine (no operating systems at that time, ca. 1960). The S2002 was a binary-coded-decimal 12 digit machine, the one I worked on had 10 K words of core and 10 K words of drum, and all of that is in the simulator. I have compiled and executed Algol programs on it - the simulation on a PC runs of course faster than the original hardware at that time; do you have some timing estimates for your simulator ? Very best regards John G. Zabolitzky
