Interesting to note about Altairs...

by edick＠idcomm.com

Since it's the GUI that attracts the idiots, I'd get behind an os that has features which would defeat any attempt at GUI operation. The real problem is that the people who buy the desktop systems don't use them. They specify them and then collect a bonus, quit, and go to work for the vendor of those systems. Back about 15 years ago we started seeing some really decent engineering software for DOS. You could buy a VERY good schematic capture package for $500 (I still use mine and have yet to see anything better, even at prices > $500k) and a serviceable PCB router for $1200. Today you can easily spend $2e6 and end up with something which does NOTHING useful at all under UNIX and does little more under NT. It's the GUI, stupid . . . that's the excuse. Today you routinely pop into the GUI, run the help and find there isn't any. Many of the software vendors of the mid-80's have taken their fairly decent products, reduced their capabilities, introduced countless bugs and octupled the price, relative to inflation. We need some really stiff legislation making it an unconditional, immediate, and irrevocally hanging offense for ALL employees of any corporation any employees of which endeavor to sell software which is not fully documented. That means that documentation must predict the behavior of their software precisely to a depth of all of 2^32 inputs. That will certainly eliminate the use of a generalized GUI! How many times have you been told " well . . . that's interesting . . . we didn't know that it does THAT!"

Said term wasn't around when the CD32 was. But this WAS there era, was it not, of the CD-Interactive? That also might qualify. Also Apple's abortive "Pippen" would qualify as a proto-set-top device (and something I wouldn't mind having.) I always thought of a "set-top" box as having several qualities: It was coming out of the stereo-system/VCR/video game consumer orientation. Which means, among other things, that the remote control comes first and the keyboard is an option. You as user are some distance from the device, not seated in front stabbing at buttons. (Commodores and Apples get disqualified for this reason.) Second, there's some sense of not "turning it on and watching it boot" which has come to pervade computers.

vax behaviors

by cmcmanis＠freegate.com

I installed an ESDI disk in my uVax. It didn't work. I took it apart and discovered that the cable had been caught in the door and had ripped (flat cable). Disconnected it and the drive and the system doesn't come up to a prompt anymore. Sometimes the display on the back goes to 'F' and sometimes to 'C'. I've also noticed that my DC-OK light isn't lighting up. Is is possible I've toasted some aspect of the pwr supply? (perhaps just switching it on and off has done this) --Chuck

PDP-11 (Qbus) disk question

by mbg＠world.std.com

>How embarassing... my 11's are Qbus - NOT unibus.... Just trying to keep you honest... :-) Seriously, the comment still stands. The RQDXn controllers won't handle ESDI. When you go looking for a controller, make sure it is fast enough to handle the disks. About a year ago, I got an ESDI controller for some disks, but it wasn't fast enough (at 10 Mbit/s) to handle the disk I had... But the Andromeda ESDC (at 15 Mbit/s) worked just fine. Oh yeah, I just realized I screwed up too... the KFQSA is DSSI, not ESDI (so many TLAs, so little time)...

Interesting to note about Altairs...

by CLASSICCMP＠trailing-edge.com

>This is the point isn't it? Finding an Altair at a garage sale or swap >meeting in Bloomington Indiana would be like finding the Holy Grail in a >pawn shop, not friggin likely. Really? I managed to scavenge up a half-dozen IMSAI'S and almost as many Altairs in a couple of years in Southern California in the early 90's. Then again, I didn't just scout around at garage sales - I hooked up with the owners through local clubs, business associates, etc. Or I frequented places that do industrial-type surplus. I wasn't particularly targetting IMSAI's and Altair's, these acquisitions came about mainly in the course of looking for other stuff. There's a few lessons here, I think: 1. Never define what you're looking for too narrowly. There's lots of interesting stuff to play with out there - you don't need any particular brand/model/serial number of computer to enjoy them. 2. Be willing to call or visit anywhere in a 50-mile radius at a moment's notice. 3. Be dedicated, don't give up, and get lucky :-) I honestly don't think anyone can complain that there aren't interesting things out there to collect. In the past decade, I probably averaged 8000-10000 pounds of stuff a year (then again, I'm mainly interested in minis and industrial controllers.) Tim.

HP-85 belts/Capstan repair

by msg＠computerpro.com

Greetings to all: Since I've been absent for about a week, 800 messages have piled-up >from the list; reviewing them will take awhile so I'm posting this to report on the HP-85 belt/capstan issues status globally. The belts have arrived and are being mailed-out early this week. I installed a set in our HP-85 and they work well. I tried a new approach to capstan repair which I find works very well. Clean the capstan of old rubber down to a minimal amount of residue with isopropyl. Obtain a can of dipping vinyl (for coating tool handles, etc.); most hardware stores should have it. Remove the capstan/encoder wheel ass'y from the motor shaft. Prepare the vinyl properly according to directions with the product. Dip the capstan (inverted) at the rate of about 5 seconds for its length, being careful to just dip just above the bottom rim of the capstan wheel so that the vinyl creates an overlap of 90 degrees. Withdraw the part at the same rate as insertion. Immediately invert the part and place on a level surface in a warm place to dry for four hours. During the drying time you will note that any vertical asymmetry evens out. Repeat with another dip and 4 hour dry. The results were very good and tests with an old tape containing an 84 record program produced no errors (reading or writing). Attached is a small jpg which gives an idea of the appearance of the results (max mag. avail with the camera lens). Michael Grigoni Cybertheque Museum

What classic equipment was rebadged?

by CLASSICCMP＠trailing-edge.com

>Rebadging was more prevalent earlier when everything had to appear to come >from the same company, but these days it is accepted that pieces come from >here and there. Since the advent of the PC-clone industry, it is accepted that lots of hardware items are "no-name", with no indication of who manufactured it, where it was manufactured, and usually minimal or zero documentation about the product. (OK, some of this no-name stuff predates the PC-clone industry. Apple ][ clones in the Lasnerian mid-80's are also examples that comes to mind.) Tim.

>IIRC, the DSD drives _can_ format floppies. Absolutely, in both RX01 and RX02 modes. If you have the DSD-440 hooked to your PDP-11, you can just boot the utility floppy that came with the DSD-440 and it gives a menu letting you select from several different diagnostics and format utilities. You don't even need a computer hooked to the drive to do it - you just set the hyperdiagnostic DIPswitch pack on the in-box controller to format the floppies, and let it rip. Never, ever, lose the hyperdiagnostics section of your DSD440 manual!

PDP8/e /l music compiler

by lemay＠cs.umn.edu

I have a listing (green bar) of the PDP 8/e and /l music compiler. Is this something of value to someone, or has this already been archived someplace? As far as I know, this may have been written here at the U of Minnesota. I assume the Pascal Compiler that was written here is already available someplace (it was once distributed by Decus). I have the original floppies that were submitted to decus and returned by decus. -Lawrence LeMay

Anyone want a Kontron?

by kyrrin＠bluefeathertech.com

Somehow, I have doubts that I'd be able to sell this at the local swap meets, and I'd rather it go to someone who may be able to use it anyway. I've got an old EPROM/PROM programmer, built into a nice Zero/Haliburton aluminum briefcase. It's a Kontron MPP-80, comes with a couple of adapters and its manuals, and it also has a built-in UV unit to erase EPROMs with. When I first got it, it would not fire up. After some intensive troubleshooting, I found and fixed a couple of problems in the power supply. It seems fine now, but I have absolutely no use for it. If there's no interest here, I'll post the thing to Haggle. I wanted to check with you lot first. If you're interested, drop me a note with an offer. Thanks in advance. -=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=- Bruce Lane, Owner and head honcho, Blue Feather Technologies http://www.bluefeathertech.com Amateur Radio:(WD6EOS) E-mail: kyrrin(a)bluefeathertech.com SysOp: The Dragon's Cave (Fido 1:343/272, 253-639-9905) "Our science can only describe an object, event, or living thing in our own human terms.

Most recent haul

by jpl15＠netcom.com

Saturday evening I went to a friend's business who was subleasing part of his shop to a gentleman doing 'surplus' here in Southern California. The gentleman regretfully passed away suddenly around New Years, leaving a lot of Stuff behind, which we are liquidating for the man's estate and widow. So: here are some DEC/classiccmp related items, a few of which might be of some interest to list-members. I bought these items as a lot, and will indicate which are available to the Community. (*) Two Siemens System 300 desktop card readers, still set up for 230vac/50htz. * Some kind of DEC test box, in a large blue alum. case, marked only model 93-07402, containing an RX02 disk and a printset; the disk is marked DGSBA.A11 (S/X REC.) and the printsets are marked SX TRANSLATOR.* Three nice leather shipping cases containing RL01/2 disks: in one, three disks RLO1K DX-T502K-MC CZZLDK0 DLDP V2 RL1 DIAG Pkg 1 Pkg 2 Pkg 3 in the second, 2 disks RL02K BC-EH95I-MC CZZLOTTO DLDP V2 R2 DIAG Scratch In the third, 2 disks RL02K BC-FI18S-DE 000MUB9526 VAX 8600/8650 CNSL W/DIAG (Both disks marked the same) * A PMK05 Unibus Exerciser w/doc and two paper tapes marked: MAINDEC-11-DZKUA-C-PB 6/3/76 nr Unibus Systems Exerciser Diag. MAINDEC-11-DZKUB-A-PB 3/24/76 nr Unibus Exerciser Module Diag. A Wilson Laboratories SX-530 Disk Memory Exerciser, set and cabled for SMD devices (wooo-hooo!) With doc and adpaters, and a supplement for FUJI units. A Pertech card-sized laminator with a hundred DIGITAL logo cards and plastic carriers for them, waiting to be laminated. A Digital portable fiche reader w/two lenses (24x and 42x) [Visidyne]* A Massbus T.D.R. adapter for the PDP-10... hooks up to a Tektronix 1502 Time Domain Reflectometer to diagnose Massbus continuity and signal integrity. With docs and adapters. (No Tek 1502, though... damn!) Manual says: "TDR testing of Massbus I/O bus, Memory BUs, and Channel Bus. * A VAX 8600/8650 Backplane Repair kit and manual marked "Backplane Repair Seminar Manual" This kit is in a nice Halliburton case and is full of all those wierd and wonderful tools, all made of unobtanium. * A TU58 dual external drive with cables and M8043 and Pocket Service Guide. A PRS01 portable paper tape reader with service docs, many cables, and DLv11 card... geared for slow speed. A Digital-badged Termiflex handheld data display/entry device... looks brand new... two lines of about 24 Alpha LEDs. A Fluke 8020 Dig Multimeter in a leather case w/Dec markings. A T.I. Silent 700/707 Very Tiny terminal... about the size of an EPSON HX-10 or Radio Shack 100... in a well-worn heavy cloth carrying case, complete with detached acoustic phone coupler, power brick, and one unused roll of thermal paper. There is more DEC-related stuff still at the place, including maybe 6 or 7 temp/humidity circular chart recorders... more of the Termiflex units.. about ten more suitcase-type testers and exerciser boxes, and about a ton of non-list-realted test equipment I'm going to sort thru in the next few weeks. Any interest.. please e-mail and I will forward further info. Cheers John

18 Classic Computers Delivered, a beaut day.

by guerney＠uq.net.au

For so long on this list, I have been reading about peoples "good days", "lucky days" and so on. Now at last, I can talk about my "real beaut" day! A local collector, not known previously to me, put a post on one of the "aus.forsale" newsgroups saying he wanted to thin out his collection, and he preferred a person take the "off-load" as one lot. Thanks to a "heads-up" >from Andrew Davie, I got in first (as it turns out, no one else offered to take the lot) and the previous owner even volunteered to bring it all around in his van. The delivery consisted of: EACA Genie III, an all-in-one 2x5.25" and monitor (TRS-80 compatible and CP/M) CPT 8525, an all-in-one 2x8" drive and page-view monitor Spectravideo 328 with 605 Expander containing 2x5.25" drives and 80 column card Hitachi MB6890K ("Peach") with Hitachi MP-3550 dual floppy and Hitachi monitor Hitachi MB6890K (another) with 3rd party dual floppy unit and two other expansion cards IBM 5150, made in the Wangaratta plant in Australia that IBM ran for a few years, with a 64K-256K board and cassette connector IBM DisplayWriter (Model 6580) with 2 x 2 x 8" drive units (ie 2 lots of double 8" drive modules) Digital Professional 350 but without its hard drive (but a double floppy) and 2 x VR201 monitors TRS-80 MC-10 with 16K expansion TRS-80 Model III 16K with no drives TRS-80 Model III 48K with 2x5.25" drives TRS-80 Model 4 64K with 2x5.25" drives TRS-80 Color Computer 1 TRS-80 Color Computer 2 with NEC PC-8032B dual 5.25" disc unit and TRS-80 Line Printer VIII VIC-20 Dick Smith System 80 cassette system Microbee Series 2 Colour Microbee Series 3 128K with Microbee Disc System (5.25" in large shoebox) And all the previous owner wanted ... a swap for my Apple ][+ which he needed for a project he was working on now. Thanks Chris, if you are reading this, much appreciated and valued. Shouldn't be too hard to find another ][+. Of these computers, the CPT is the least known (to me). I can find only one mention of it on the Web and that guy didn't even have a boot disk for it. At least I have some 8" disks (don't know if it works yet, still got to do the preliminary check-out before applying power). One of the floppies says "Tandon CPT" on it (hand-written) and a sticker somewhere suggests it was built in Ireland. I'd appreciate some more info on it. Hardly anything on the net about this chunky IBM Display Writer either, its not even on the Comprehensive Computer Catalog as far as I can see ... Anyone got a spare monitor cable for the Hitachi Peach's? (Luckily, they also have B&W monochrome output so I can see that this system works). Now, I've got plenty to do for a while ...

disassembling a monitor

by yakowenk＠cs.unc.edu

Okay, this is stupid. It should be a simple thing. But, as I always say, better safe than dead. So... Can anybody give me pointers on disassembling an IBM 5151 monitor? I rescued one from a dumpster, but it seems to have something metallic-sounding loose inside. Since it sounds like metal (and not glass, for instance), I want to remove it (or properly attach it wherever it belongs) before powering up. I can imagine all sorts of bad things that a loose bit of metal could do inside a monitor with the power on. I know enough to avoid the high voltages once I get inside, but would much prefer to get inside without breaking the CRT's neck. The enclosure is made of two parts; the front that fits around the face of the CRT and the front half of the bottom form one piece; the remainder is the second. When I set the thing on its face and remove all screws in the second piece, the front half of the bottom flexes inward under the weight of whatever is attached to it. It does this enough to worry me - any attached innards must be getting closer to the CRT's neck when that happens. Help? Thanks in advance. Bill.

AMSOFT on DISK

by jim＠calico.litterbox.com

*nod* Ours were well into the million pages throughput. This was a college housing department, and we were running ALLIN1 desktop on our vaxcluster so an obscene amount of printing fell to our 2 LN03s (one per floor of the admin building). And yes again, the one that overheated DID have a fan motor problem. The fact that they stood up to this constant abuse speaks well of them, to be honest. And actually since I know the vaxcluster is still in place at that site (I ping it from time to time out of curiosity) I shouldn't be surprised if those printers are still there, 6 years later. ><Nice enough laser printers for their day, but they tend to overheat, if ><memory serves. If you get one, make SURE the fan works. Check. I seem ><to recall we had problems with those on a Vax site I worked on once. > >Only if the fans are missing or dead. I was part of that design team and >overheating was never a problem. The most common problem was a printer >designed for an peak use of 5,000 pages a month being used as a line >printer.

historical question - paper tape vs. punched cards

by jlwest＠tseinc.com

Just a curious question: Which came first, paper tape or punched cards? I'm not concerned about "invention" dates, I'm more interested in "came into very common use" dates. Actually, I'm not concerned about dates either - just which one came into very common use the first. Always wondered - thought people here may have an idea. Jay West

OT? Tek Scopes

Visiting a surplus shop today, I found a small herd of Tek Oscilliscopes. Some of them looked pretty old to me. They want real money for them too. Details: Model Mod 1 Mod 2 Cart ----- ----- ----- ----- 564 3C66 2B67 564 3A74 2B67 Y 504 Y 561A 3A72 2B67 5111 5A20N 5B10N 515A Y 549 1a1 Y D11 5A14N 5B10N Y 504 564B 3A9 3B4 Prices were originally $200 for most of them, except the 549, which was $400. Some of them had been marked down to $100. They have some kind of automatic decrease in price based on how long things stay in the store (1% per day?), but most of them have been there only since late February. And I don't know how that effects the ones that were "manually" marked down. I suspect these prices are outlandish. The same place wants $25 for 2400 baud modems. :-) Anyway, the age-based discount may eventually make the prices more reasonable. At least for the scopes, if not the modems. The ones marked "Y" under "Cart" had a "Scope-Mobile" cart with them. But I didn't think to get model numbers from those. Oh, and I can't guarantee that these work. I didn't ask if they would allow me to test them, and at present I don't know enough to be able to test them anyway. I also can't guarantee that they'll still be there when I next visit. Questions: 0. How old are these guys? 1. Are any of these potentially useful for computer work? Can they handle the frequencies used in old machines, say, up to a few MHz? (Judging from their apparent age, I wouldn't hope for much more than that.) 2. Anybody want one? Be aware that in addition to the price tag, I wouldn't expect these guys to be easy or cheap to ship. (At least one time in the past I have had to back out of a deal because I couldn't arrange shipping within cost & safety constraints.) And the carts are probably too big to go through UPS or USPS. Given all that, if you want one, let me know. Cheers, Bill.

Computer education

by max82＠surfree.com

Hi folks, Today was the first day of my free networking course at school, at the end of which I will have received a certificate 'n stuff...anyway, the guy was trying to explain layered protocol stacks, and data abstraction. It occured to me that the concepts have no meaning outside the realm of developing the protocols or applications that use these protocols. And it's almost impossible to explain without referring to these realms. The guy was telling us how 'everything in the computer is in binary' but you need additional network layers 'because Word can't understand the binary and needs it to be translated'. At this time, I was thinking about my recent experiences with the PDP-8. I wonder, wouldn't it make everything so much easier if every computer in schools had a PDP-8 emulator on it, and students had to learn to make simple programs in PAL before learning concepts like the OSI 7-layer model, etc? Because, it was obvious that the guy was being forced to avoid saying the word 'function' or 'subroutine' since people didn't know what it meant.... --Max Eskin (max82(a)surfree.com)

It's unfortunate that the course was so top heavy with out a foundation to hold it up. FYI: I have a copy of a pair of articles going back to the only MicroSystems (1983) That explains it fairly well in only a handfull of pages and then even provides a workable example wthat did not require rocket science to make useful. However the idea of data encapsulation, abstraction and arrays of data as objects are important concepts that need to be learned between adding two number on a PDP-8 in PAL and the higher level application of 5GL languages and networking. It's the side effect of knowledgeless people prescribing course goals and content. Allison

The TI 34010

Most VRAMs (certainly the ones in use when the 34010 came out) seem to be nothing more than DRAMs with a second address port that transfers one row of data into a shift register. The bitstream from the S/R is fed to the video circuitry. No bit-blit operations. The 34010 has instructions for raster operations (bit-blits) using data anywhere in the address space, and they don't appear to depend on features of the RAMs used. -tony >> There is in fact both: the processor can do it, but at least the VRAMs I looked at have some provisions for (simple) versions of that.

Saturday Auction fun and finds

by mikeford＠netwiz.net

Sorry to repeat this, but I forgot to change the subject and didn't want to have start some thread of confusion (which it will I am sure anyway, but sorry). Once about every three weeks a place in Huntington Beach Ca has an auction of computers, its not what it once was, but it still is entertaining. Main course today was 1150 old 486 computers along with 500 other lots. I didn't buy any of the 486's (just 10 macs), but I did see and buy some interesting items. Epson HX-20, circa 1983 portable computer with a microcassette for storage and a builtin printer. This one has a expansion unit bolted to the side, and a nice slim plastic case the whole thing fits into. It must have some internal NiCads, but I haven't opened it up, and it didn't come with a AC adapter (but 6 vdc isn't too tough). Looks extremely clean, including all the rubber parts, like it spent much of the last 16 years in its case. Skiwriter word processing software is builtin, so is basic, but the only manual is for the former. Display is LCD 120x32, or 20 characters and 4 lines. Printer I suspect matches that. Almost forgot, one of its main features are the ports, serial and full RS232 via 1/2 inch diameter round connectors on the back. Texas Instruments silent 700 terminal. Looks like a typewriter, with a thermal printer and a acoustic coupler on the back. I toted one of these around for a couple years in the earlier 80s with a pager, and I remember a plastic suitcase, but this one is open. A&J Micro Drive, date on the back is 12/6/85, this is some sort of tape drive. The unit is small 1.5 x 3 x 5, runs on 4 internal AA batteries, and has a cable with a DB25 shell and 6 pins in it. Tape sticks in the front, slightly narrower than a audio cassette, and a lot thinner. Front reads SYSTEM 100, A:, and a active/low battery light. Things I didn't buy (and if somebodys wants requires quick action) A pair of Digital LN03 laser printers Xerox (I think) 645 S Memorywriter Three boxes of circa 1988 full and half height drives, most with some sort of card edge connection, others look very much SCSI. The HX-20 looks too neat to part with, but if someone wants the 700 or weird little drive I am open to it. The latter three big heavy items I am willing to facilitate, but not get in the middle of.

OT? Tek Scopes

by edick＠idcomm.com

To be down around $125, they've got to be in really sorry shape. I've seen junkers sold for that. The 465B might be lower in price than its older cousin the 465(A) because it's reputed to trigger less accurately than the (A) as a result of the compromises made in that model update. I've never seen proof of this, however. The 465's I've seen seem to sell around $400. If they're in need of work, which would make them go cheaper, they don't sell . . .

OT? Tek Scopes

by danburrows＠mindspring.com

Bill: FWIW The only to get them to come up with a realistic price is wait until after 90 days but before 120 days. Then talk to Van and make him an offer. I have dealt with them for several years. He has learned that my offers are realistic and 95% of the time takes them. He has dumpstered a lot that I had made offers on and could not get back in before 120 days. The magic # there is 120 days (the last week or the beginning of the first week of the month) That is when the dumpster gets very full. At the old location Van used to let me dumpster dive.

The TI 34010

by rmeena01＠utopia.poly.edu

The Atari Transputer Workstation (ATW) is an example of a computer that doesn't use a host. It is build upon a T800 transputer processor and runs the Helios Operating System. Another example is XTM from Cogent Research (does anyone have a picture and/or docs for this machine) which ran Linda and NeWS-based X-Windows system. It was also powered by a transputer without a host. The transputer only uses the host for I/O and for downloading the initial program. As Tony said, you can also boot from ROM and use different types of TRAMS to handle I/O without a host. For info on the ATW, I suggest you check out http://columbia.digiweb.com/kiffer/ATW/. For general info on transputers, you can see my webpage at http://skyscraper.fortunecity.com/ppp/533/. Cheers, Ram

The TI 34010

by Jgzabol＠aol.com

The TI 34020 is the (principally similar) successor to the 34010, and I have designed in my company our basic bread-and-butter product of that time around that some 7 years ago. This is machine vision, i.e. digital image processing. I do not think it is advisable to emulate anything. If you want to build the Perfect Computer (tm) I would suggest to use Linux as operating system, and write your own driver for whatever display hardware you see fit. The TI 340x0 family is best viewed as a totally general microprocessor, which happens to have a few special gadgets for image / graphics processing. There is nothing you could not do in principle by using any other microprocessor, but some things - in particular drawing graphics - will just be significantly faster on the TI 340x0. The basic thing to know is that in those days people were most concerned about putting graphics display lists on the screen, that is you have a list of triangles, lines, circles, and whatnot, and the hardware primitives (really microcode of course) on the TI 340x0 allow you to do that pretty efficiently. That in other word means, that _ON_ _THE_ _APPLICATION_ _LEVEL_ you must be prepared to hand DISPLAY LISTS over to the graphcis processor; in those times, that was done by people like AutoCad, e.g. John G. Zabolitzky

Space shuttle computers

by edick＠idcomm.com

I don't know what all this stuff means, but NASA paid Martin Marietta, where I worked back in those days, a LOT of dough, and provided documentation labeled Honeywell and showing pictures, though they were not relevant, of a model 516 computer. I spent six months or more poring over schematics, struggling to keep my eyes open, and making note of any potential race conditions, running logic simulations, etc, just to document all the potential single-point failure modes and their potential effect. We found several conditions which seemed to be "bugs" in the system, capable of creating catastrophic failures resulting in loss of lives and billions of dollars' worth of equipment, but those were "ground-ruled-out," meaning that, for example, a power supply failure in the mode wherein it drifts completely out of regulation, is a "normal" operating circumstance and need not be considered . . . but, I digress . . . The fact is, dladies and gentlemen, that the proposition of the time was that the engine controllers were Honeywell 516's, whatever that means. There was talk of installing a 68000-based computer in their place because semiconductor memories were faster, and a system of that type was superior for many reasons, not the least of which was modern read-only memories would allow much better testing. The plated-wire memories in use on the Challenger engine controllers allowed fault conditions which were not detected to be inherited from a previous mission, which risks went completely away with the newer design. It's not hard to imagine that such an upgrade would save on power and weight, as well as providing much more testability. It should also be enough faster to improve the system considerably.

The TI 34010

by Jgzabol＠aol.com

In einer eMail vom 06.03.99 10:25:15 MEZ, schreibt Derek: << > The TI 34020 is the (principally similar) successor to the 34010, and I have > designed in my company our basic bread-and-butter product of that time > around that some 7 years ago. This is machine vision, i.e. digital image > processing. I've read (I forget where -- maybe Micro Cornucopia) that the 34020 is basically the same as the 34010, except that it works with larger amounts of data at the same time. Were there any instruction-set changes? I really cannot tell, I do not recall the 34010 and do not hace any docs about it, though I do have everything about 34020. > I do not think it is advisable to emulate anything.

Then, 340x0 will not help you at all. I think Linux is very good overall. I plan on installing it on my Macintosh as soon as the quarter (school) is over. But there are some other interesting OSs too, and many of them are even relevant to the list. I've heard good things about RSX-11M, RT-11, the various TRS-80 OSs, FLEX, OS-9, SK*DOS, and others. There was also a competitor to CP/M which has been praised (possibly by Allison) because it provided some important services that CP/M didn't. Unfortunately I forget if it was by Northstar, Cromenco, or Ohio Scientific. Admittedly, many of those are simpler than UNIX. But a few are real-time, which UNIX is not. Besides, almost any design is interesting in some way. I also have visions of putting together a Transputer-based system and somehow creating vast amounts of computer power out of thin air. :) From my reading, it seems there are two main drawbacks: 1) Generally, the Transputer depends on a host. 2) Parallel processors are very powerful but they won't solve every problem equally well, and they present some very subtle and nasty traps to the student or programmer. Maybe it's time for Tony to come back into this thread, since he seems to be the Transputer expert. I have done quite some work on parallel systems; the efficiency and ease of programming depends _TRMENDOUSLY_ on the problem you are looking at; some (like Monte-Carlo simulation) just fit perfectly well, others (like running canned software) not at all. Of course, it will be mandatory for high-performance computing in the future, in fact is already today, to go parallel; in all cases I know at tremendous work on the algorithm level parallelization. My personal preference is in shared-memory parallel processing; the transputers are message-passing parallelism, which I personally do not find very useful. But that depends of course on the problems and algorithms I am interested in. > faster on the TI 340x0.

I understand display lists pretty well. Many vector-graphics machines used them; Sketchpad relied on them and Evans & Sutherland continued the trend. (I'd love to play with some of their machines!) Also the Atari 8-bit machines had a limited form, and you could say the Amiga has them as well. This kind of dipslay list relates to memory layout and interpretation, rather than defining objects in memory. But it still makes certain tasks absurdly easy, instead of very time-consuming. > That in other word means, that _ON_ _THE_ _APPLICATION_ _LEVEL_ > you must be prepared to hand DISPLAY LISTS over to the graphcis processor; > in those times, that was done by people like AutoCad, e.g. How does the 34010 do in handling bitmaps? The 34020 (and I believe the 34010 had that as well) deals with that through special bit-blit operations, bit-block-transfer and simultaneous logical/masking operations. This is much supported by VRAM hardware used at that time; the VRAM chips have bitblt features built in. The performance was exactly equal to the VRAM theoretical max throughput, i.e. the TI processor made the best possible use of available memory technology. -- Derek >> John.

Was very easy to develope, because: 1.) the transputer supported DRAM directly 2.) debugging was easy, because you could download the programs via link 3.) pin compatible versions with/without FPU (FPU was used only for postscript) 4.) Lots of application notes & support from INMOS at this time. Just my .0002 cents cheers, emanuel

collectible digital cameras?

by lgroebe＠insidermarketing.com

Having just returned from another depressing First Saturday trip - loads of PC clones and scanners, one nut selling a core memory board for $1000 - and oh yes, a Timex 1500 I bought for $3, I find myself wondering what possible post-Windows3-era stuff can be/will be possibly considered collectible some day. It occurs to me that one candidate would be the first batch of digital cameras. So made the first consumer-level digital camera? Kodak had a hi-end modified Nikon about 7 years ago, but I'm thinking the Apple QuickTake 100 is the earliest digital camera I can think of. And are there other categories of products that might become future collectibles? --Larry

I thought about building a controller, and adding these boxes (about 2 cubic meters each) to a PC in opposite movement to current hard disk evolution. So I will need to wait until some nice 14" drives come around. Some years ago, I indeed DID build a controller for some CDC 14" drives, to add onto a MC 6800 system (6800, NOT 68000 !!). That is not too difficult, since the drives usually contain already some hardware to take care of the servo functions, which is the most critical part, and of course write drivers/read amplifiers.

Mac IIci stuff

by max82＠surfree.com

Hi, Is there any demand for Mac IIci manuals and system disks? I may be able to spread a few around. Also, hypercard manuals. Some still shrinkwrapped. We have a pile of complete IIci systems that we don't know what to do with, since they've been recently replaced by Quadras and translucent blue towers. Any place that could make use of them and _not throw them away_? We might donate a couple.... --Max Eskin (max82(a)surfree.com)

Fullerton CA GSA finds

by mikeford＠netwiz.net

I was roaming the local GSA surplus depot and have the following to report; Pallet lot of DEC manuals about 5 feet high, boxes and boxes of ringed binders, and a bunch of paperbacks still in shrinkwrap. labeled $60 System Industries tape drive, like a VAX used in a 5 foot high 4 foot deep very nice cabinet. label $100 Large box of tapes 600 to 6250 bpi, I didn't notice a price. Pallet of 11 items, including old printers, but also a Tandy 1000, and a commodore Amiga, and other stuff I didn't ID. label $250 The routine discount from labeled price is 60 to 70% off, but they want to get rid of these items, so be creative. GSA surplus depot is listed in the phonebook and has a web page. http://www.pd.dgs.ca.gov/materials/surfull.htm

Reading old SCSI tapes

Hmm, well presumably a Linux bootdisk can be made that'll have dd on it as well as a SCSI-based kernel and MSDOS filesystem drivers, that way no OS needs to be installed and the tape data can be written to one of the PC's hard disks... of course, this assumes that dd is sufficient to read the tape (as somebody pointed out), and that the PC is using a FAT-based filesystem on its disks, not NTFS. cheers, Jules >

Hi, Could someone who is subscribed to the digest version of the list please (compress and) email me a copy of digest #698? I lost it due to problems with my mail software. Somewhat on-topic question: can someone recommend a program, to run under MS-DOS (or maybe Windows) that is capable of reading a file (in the tape sense) from a SCSI tape drive. Not interpreting the file at all, just being able to copy it to disk. -- Mark

'dd' will also throw away all the original blocking information on the tape. Many platforms and OS's will depend on finding tape marks and varying record lengths, and if you just 'dd' the tape all this information is lost. I've made a good amount of money over the years recovering RSX-11M BRU tapes where someone transferred the tape through a Unix system with 'dd' and lost all the blocking information. Most Unix-like OS's come with "tc" or a variation that will display tape blocking information; often folks take the output of "tc" and use this to create a script of "dd" commands that will handle the various block sizes on a particular tape. Under RSX-11M and VMS, I much prefer "TPC" format, which allows exact tape images to automatically be made with all the blocking information preserved. -- Tim Shoppa Email: shoppa(a)trailing-edge.com Trailing Edge Technology WWW: http://www.trailing-edge.com/ 7328 Bradley Blvd Voice: 301-767-5917 Bethesda, MD, USA 20817 Fax: 301-767-5927
