Thought y'all might be amused by this tidbit from another list: "This reminds me of something I heard about earier this month. It seems some researchers decided to create a breed of super-intelligent lab rats by the simple process of artificial selection: in each generation, only the rats who were the fastest at solving mazes would be bred. Result: After seven generations, the researchers had created a colony of rats who were clumsy, near-sighted, antisocial, and totally inept in their dealings with the opposite sex." -- Warbaby The WebSite.

Curious. I am wondering what would happen if such a thing were actually done. It would probably make a bunch of rats with identical times,at which point the experiment would be over.

Well, score one for Classifieds 2000. I just got a C128 system with 1571, printer, and software (including all the *ORIGINAL* disks that came with the 1571) for $35. If anyone needs copies of 1571 stuff (including a C128 CP/M boot disk) lemme know, I have two 1571s now and can make disk copies rather easy.

by fauradon＠pclink.com

I believe it is relevant to the list for people who might be in the area at the time. If I'm trveling to the bay area and see that there is a get-together going on at the same time I would make sure to attend. This invitation is not reserved to people living in the Twin-Cities but to all and that includes travellers. I used to do quite a bit of travel for work and had nothing to do with my evenings. Sure the chances are slim but still it is worth the added messages. It sure beats IMHO discussiond about guns or other means of destruction.

Looking for parts...

by jimw＠agora.rdrop.com

Picked up a new stack of systems, one of which is an Ithica Intersystem DPS-1. If you have ever seen one, it looks suspiciously like a PDP-11 console. Or at least it would if this one had its dress panel... On the longshot front then, does anyone have a spare (extra, random, looking for a home) front bezel for one of these units? Or even a (more or less) complete chassis looking for a new home? It is also missing a couple of switch levers. The nice bright orange ones. This unit even has a bit of a history. Before it came to me it had been a development system at Digital Research (yes, THAT one) In fact it came along with a great deal of materials most of which have been forwarded along to Tim Olmstead for addition to the CP/M Source Archives. Apparently, they did not have much use for the dress panel on the machine (hardware tinkering and such) and it had been lost for some time before the machine came to me. (darn) So... any help appreciated as always! -jim --- jimw(a)agora.rdrop.com The Computer Garage - http://www.rdrop.com/~jimw Computer Garage Fax - (503) 646-0174

I'd suspect the Gunsmith would possess the tools needed. It doesn't take a larg machine shop to do many of the processes needed to make a firearm same applies for computer. A case can be made of easily machined plastics or even wood and painted for protos. I made a system box years ago out of wood to simulated the look and feel of a quality epoxy glass resin, no majik other than knowing how. Allison

OT RE: BLAM, BLAM, BLAM! ;]

by peacock＠simconv.com

> Oboyoboy! Do these folks have any Barrett Light Fifties? I always wanted to try out a rifle that could remove a shooter's shoes for him! kaBLAMMMMM! ;] Nope, out of luck, all they have are pistol and submachine guns, after all, it's an indoor range, a .50 BMG would go right thru the wall and the building next door too. Indoor ranges don't have the backstop for any rifle rounds, so no AKs, FALs, Galils, any of the good stuff either. BTW a friend of mine makes a printed circuit type card for a computerized chronograph used to measure 20mm rounds for an ammo manufacturer. They actually fire the round thru the card, and use the break in the circuit to control the chronograph. Because of the size and amount of gas generated by a 20mm round, a regular chronograph using sky light doesn't work, not accurate enough. The card is actually silk screened conductive ink on cardboard. Yeah, I'd like to have a Barrett too, but $5K is a bit too steep for me, unless someone would like to trade for a nice IMSAI with front panel? Then there's the cost of dies and a reloader for .50BMG rounds... Jack Peacock

Shame, shame, shame

by peacock＠simconv.com

From: Sam Ismail [mailto:dastar@ncal.verio.com] >Sad. That was probably perpetrated by those Israeli guys in Las Vegas who rent out machine guns for an hour or whatnot so you can blast away at stuff. I'm not kidding, this place exists. Northwest of the strip I think. There are at least two places west of the strip, Shooter Supply (the nicest one) and The Survival Store, that rent out or sponsor machine gun events. Both are close to my office. I think there are a couple more on the east side of town. These ranges are very popular with Japanese tourists. Typically they rent out Uzis, Thompsons, MACs, and the usual generic batch of 9mms.

Driver Needed

by roblwill＠usaor.net

I'm looking for a driver for a "Micro Mainframe Expanded Memory Expansion Board" (yes, that's the actual name of it). The model number of it is EMS-5150-T. The name of the driver is <EMS32.BIN>. It's for a Tandy 1000TL XT-class 286/12MHz. One other question: The processor clocks in @ 12 MHz. The 1000TL is supposed to be 8 MHz. Was there ever an upgrade offered for this computer to make it 12MHz? The chip is manufactured by AMD, and it's a 286-12 (it may be a S or SX, I'm not sure). This is also the computer that I'm trying to find an XTA drive for. Make or model doesn't matter, as long as the heads aren't run by a stepper motor. ThAnX in advance, -- -Jason (roblwill(a)usaor.net) ICQ#-1730318

Altair - A different perspective

by peacock＠simconv.com

> >I'd love to see a manual for the chipset and microcode information. > > I think the burning question would be: How does one debug somehting > like this? For a commercial company, microcode is tested and debugged on software simulators before the hardware is even completed. Once the architecture is defined, software is developed in parallel with the hardware to simulate the components. Microcode is tested on the simulator, much easier than using a scope and analyzer. Course, the component descriptions given to the simulator programmers (these are usually programmers with a good EE background who understand boards at the chip level) had better be accurate. And in parallel to that, an emulator is also done for the target instruction set. This allows systems programmers to develop the initial assembler, compiler and operating system for the new CPU. That's how a completely new CPU design, with no backward compatibility, can appear all at once. By the time the hardware prototype is ready, there is a complete set of diagnostics and an OS to boot up. In theory that is ... Tracey Kidder's book, The Soul Of a New Machine, detailed some of that process when Data General switched from the 16-bit Nova to the 32-bit Eclipse. Jack Peacock

a2 power supplies

by jim＠calico.litterbox.com

Hi gang. FYI Jameco has power supplies for apple2,2+,2e, and 2GS. 49.95 each, 60 watt units, original equipment style. If you're thinking of one of these you might ALSO want to think about something called Bugg power - a guy on the a2 newsgroup (comp.sys.apple2) who takes pc XT power supplies and adapts them to plug into apples. Since the average XT PS is 145 watts, the apple no longer has power problems (and you barely have to run the PS's fan) and it gets the power supply and all that heat out of the case altogether. (it sits on the floor ala C=64 power brick). I've never used one of these things, but the reviews from people who have are glowing. As for heat, I noticed in my GS last night it gets right toasty in there, and the power supply is almost too hot to touch. I expect to be PS shopping shortly. :( -- Jim Strickland jim(a)calico.litterbox.com ----------------------------------------------------------------------- Vote Meadocrat!

Of course, the amount is irrelevant. Particle accelerator experiments have not been able to split lusers up into any constituent parts. In fact, they may be the elemental particles of intelligence. Of course, if Congress funds my new Me^H^H ultra high-powered particle accelerator, we'll be able to test this once and for all.

prototyping (was OT: BLAM...)

by peacock＠simconv.com

>Curious. Same goes for people who aren't in a large company and invent various other things. How did he 'invent' a gun without owning the necessary tools (at least I doubt a magazine writer would own this stuff) to process metal? Also, how did Woz make a case for the Apple ][, etc? Are there companies that take single orders like this? There are companies which will build one off prototypes for you. They are usually listed under something like custom electronics or fabrication services in the phone book. Building a prototype is not cheap, the cases, parts, whatever are usually hand machined. Even plastic cases, since an injection mold would run you over $10K in startup costs. Disclaimer: I'm part owner in a company that does this. We have a substantial investment in machine tools (mills, lathes, welding, plasma table), a glass shop (neon and cold cathode tubes), plastic machinery (ovens and router tables), and a paint booth. It's an interesting business, everything from small computers the size of a deck of cards to 2 ton exhibits for computer companies. As for Elmer Keith, he didn't start from scratch. He adapted existing cartridge cases by milling out dies. It's not as complicated as it sounds, some wildcat (i.e. not production) cartridges can be produced with nothing more than hand tools.

Pascal Micro Engines

Shure, bur the PMS (*G*) utilizes the p-code engine as native Code - at one time the UCSD p-System was a kind of a ruling cross platform and cross language standard. The 'p' of p-System was 'pseudo' not 'Pascal' as most people belive - they had compilers for Pascal, Fortran, Cobol and Basic - all using the same p-code engine to run ans all using the same 'OS'. So to get the system on a new nmachine you just had to write some low level parts of drivers, and, if the new system had a different microprocessor, a new p-code interpreter - whoops, and everything was running. Cross platform development was an easy thing - write one application and let it run on PETs, Tandys, CPM/systems, of coure on APPLE ][s and even on IBM-PCs - oh, did someone say Java ? *grins*.

Which track was least reliable?

Don Maslin wrote: >On the other hand, one of the outer tracks - the one that contains the >directory - is accessed much more frequently than any other. It is there >that I have experienced the greatest number of failures. This is true for many operating systems on many computers. Often in the 70's and early 80's drive manufacturers would put circuitry in the drives that would randomly move the heads off the directory tracks after a certain period of time of non-access. (I have several Kennedy 14" SMD drives that will do this. They have the nice feature of a clear enclosure so that you can see what exactly the heads are doing at any point in time!) Tim.

Tektronix 4052 instruction set

by Philip.Belben＠powertech.co.uk

I have had a look at the TEK 4052 instruction set against that of the Motorola 6800. Most of the 6800 instructions are present - the one exception is DAA. Tek also introduce 43 new instructions, but I don't know what any of them do except NOP2 which presumably doesn't do anything at all. More reading required on my part, but I guess a port of FLEX wouldn't be too hard provided it could cope with the BIOS, which on a storage tube machine is bound to be weird. That said, the Tek 4052 has a far better line editor than many non-storage environments I've met... BTW, I've had one request to provide a write-up of my VCF talk for those who can't get to the VCF itself. Is there any demand for this? Sam, do you want this for imclusion in a "conference proceedings" sort of document? It will be difficult, though, to include all the demo program outputs (must get my plotter working again!), manual pages, etc. Philip.

Sol terminal computer

by bobstek＠ix10.ix.netcom.com

IMHO, the Sol is the next most important early commercial microcomputer after the Altair and IMSAI. Although it had 5 S-100 slots, it really was a single-board computer with built-in 64x16 video, serial and parallel ports, keyboard, cassette tape interface, and ROM monitor which supported its use as a serial terminal supporting VDT escape sequences as well as being usable as a true computer. Cassette-based software included 5k BASIC, 16k Extended BASIC, FOCAL, PILOT, ALS-8 (Assembly Language System), arcade style "real time" games (Target, Trek80) as well as BASIC games and 8080 Chess. Its 8" Helios disk system was expensive and the PerSci drives finicky - which is why so many SOL users opted for a NorthStar controller and 5.25" drives. Contact jordan_ruderman(a)supermac.com - he has been compiling an audio CD-ROM of all the cassette software. You can substitute a portable CD player in place of the SOL's cassette player, or just dub copies onto cassette (to capture that ol' time flavor!). Also, if your keyboard is acting flakey, it may be because the little foam pads inside have deteriorated over the years. Contact Jim Willing at the Computer Garage http://www.rdrop.com/~jimw for DIY replacements or he will do it for you. Jim is very knowledgable about SOLs.

I'm Back!

by Marty＠itgonline.com

I agree that there is no cure for stiction but on the older 3 1/2" FF HDD's I used to gently nudge the spindle flywheel under the drive board. This would free the head of the platter goo and typically the drive would spin up and boot at which point a complete backup was made. ______________________________ Reply Separator _________________________________ Subject: Re: I'm Back! Author: classiccmp(a)u.washington.edu at internet Date: 8/23/98 1:25 PM > certain hard drive of mine won't spin up unless whacked firmly > against a table? Is there anything I can do? This is a laptop drive. >> > > stiction. nothing you can do about it. > Actually an ex-friend of mine had a technique to 'sticky' drives. The theory goes if it's hosed anyway and you need to get data off it, you can do things to it that you wouldn't ordinarily do and what do you have to lose? At any rate, I've used it before and it seems to work on X percent of drives that are totally stuck (especially ones that won't start up even when whacked). You put the drive top-down (circuit side up) on top of a nice toasty monitor and just leave it there for several days or weeks. I don't know if this loosens up some lubricant, expands whatever's sticky or what but if you take the drive off the monitor and hook it up immediately and start it up immediately...occasionally you can get it to spin up and give you your data. The opposite of this is a drive I had (old Miniscribe 20 meg SCSI) that would run for about 2 hours, overheat and 'shut down' (it wouldn't spin down...it'd just start giving errors and was generally useless). I knew it was heat because I could extend the time-till-shutdown to about 3 hours by pointing a small muffin fan at it. I had NO money at the time...except for rent money I was flat broke...and couldn't afford to replace the drive and...seeing how it was 1991 and I live in the backwater state of Iowa, nobody would loan me a replacement. The Mac SE it was in was also out of warranty. At any rate, since it was winter it was cold outside so I wrapped the drive in a plastic bag, sealed it up with duct tape around the SCSI cable, set it on the ledge outside the window, closed the window without squishing the cable and sealed up the crack with duct tape. Left the machine and the drive on for something like 2 months that way (though my memory is a bit rusty there) until I could save enough money for a replacement. I was worried about condensation inside the bag but it never caused a problem. At one point, the drive slid off the ledge and was dangling by the SCSI cable and power cable but the duct tape held it firm. It ran like that for several days until I noticed it wasn't on the ledge. On a related subject, I've seen and had several Syquest 40 meg drives that wouldn't work and wouldn't work and wouldn't work until you flipped them upside and then they'd work just fine. Not the cartridge...the whole drive. Which reminds me...I worked at a typesetting shop once and a guy from another department walks in and tells me he's accidentally formatted his syquest cartridge and is there any way to get the data back? So, with a room full of people who knew better I told him, "Oh yeah...if you just flip the cartridge over, that'll run it backwards so that if you format it again, that'll do the reverse of formatting it and you data will be back." I figured he'd know I was kidding but he DIDN'T and starting walking away to DO IT! I stopped him fortunately and recovered his data with proper tools. Of course, a couple months later he thrashed the innards of a $1500 magneto-optical drive by jamming an 80 meg syquest cartridge into it REAL HARD. I patiently explained to him that when you hear snapping sounds and grinding metal you're generally doing something wrong.

more info on systems....

by poesie＠geocities.com

well, I found out none of the NEC versa laptops are for sale; apparently some VP is holding onto them for some reason. We have maybe 30 7100/66or80 PPC macs; most with 16-32 mb ram, additional vid cards, token ring. IIci's, about 15? with 20mb ram each. 6 Quadra 950 servers with typically 2 300mb scsi drives and between 25-50 mb ram. ummm... maybe 50? or more DuoDocks, both the Duo 230 or 280, and the Dock. don't know the possibility status of selling these. several sony video monitors that are touch screens, accept various inputs, came with weird computerized videodisc systems. we used to sell these things as scrap, and paid! them to take them, and then got rebates for 10cents a pound, or sometimes we ended up owing them. He is actively looking for vendors to buy, so we could probably make an offer for pallet(s) since I'm the only one doing any work with them. I will also do the legwork in my spare time, for this. However, someone else should be the point man, so to speak... I can't really get involved. I've tried, believe me. I'll try to do some more inventory type stuff... But there's alot. Also a whole room full of an IBM 3480? mainframeish type of thing, with disk boxes etc. looks like a room full of washing machines... -Eric

Name this chip

by Anthony.Dellett＠Staples.com

It's a really wacky IC. It's a 68 pin package. Looks kinda like this | | | | | | | | | | | | | | | | | | | | | | | | +-----------------------------------------------+ | +----------+ | | +-----+ | | | | | | R | | | | +-----+ | | | | +----------+ | +-----------------------------------------------+ | | | | | | | | | | | | | | | | | | | | | | | | Both the boxes are ceramic squares (grey ceramic, like an eprom or something). The little R looks like a surface mount resistor or cap. The bigger ceramic square has: SMS300-1 0002624 001 A 7620 on it The field of the chip is white with grey zebra stripe lines running to each of the pins. On the top of the IC is screened: 00020730001C In gold and on the bottom: SMS INC 2075-0001 In black. What the heck is this thing?!?!? I know it's probably an engineering sample, but of what? Tony

Hard drive adapters

by roblwill＠usaor.net

Does anyone out there know of some sort of gizmo that could be made that would convert an old RLL or MFM Hard drive to be used with a parallel interface? I've seen then for IDE, but that's it. I've got a couple of old HD's laying around that I'd like to put to use, but there's no room in any of my computers to put them. By the way, does anyone have any old Apple or TRS-80 external disk drives that they'd want to get rid of for a few bucks? I don't need the drive itself. I need the case and power supply and that's it. If they're TRS-80, I could use the drive itself, too. I'm also looking for disk-based (and tape-based) software for the TRS-80 Model III. I'm especially looking for the TRS-DOS operating system for it (floppy got ran over by an office chair *cringe*). -- -Jason (roblwill(a)usaor.net) ICQ#-1730318

But, compare a 4MB ST with TOS 1.4 (or 1.6?) with "the various add-ons" and I think you'll find they're pretty equivalent. Vastly different footprints, however, something that I find rather interesting.

There are add-ons and upgrades to GEM that do allow true multi-tasking. A quick web search should turn them up.

>On drives that store the same number of bits/track - most floppies apart >from Commodore and Mac ones, most 'raw-interfaced' hard disks (ST506, >SMD, RK05, RL01, etc), the inner track has the smallest area storing each >bit (think about it, the inner track is shorter). So PC disks are less reliable then Mac and Commodore disks, then? Tom -- Sysop of Caesarville Online Client software at: <http://home.earthlink.net/~tomowad/>

Data General

by red＠bears.org

I have recently acquired a Data General Nova and an honest-to-god Teletype---I think it's an ASR-35. My roommate is furious, but that's beside the point. The point is this machine is much older than I am; this is going to be a completely new (and fascinating) experience. I am 21 years old, and if you do the math (and if I've done the math correctly) you'll find that the Nova is 8 years older than me. I don't want to screw this up. The guy who I got it from knew a lot about it; he got it in 1982 and used it quite a lot. He told me a lot of stuff that was important, but I wasn't expecting what I got and was too overwhelmed to think to take notes. At any rate, the first thing I have to do is take an inventory, and after that I think I shall require excruciating amounts of assistence from the list making sure it's ready to be fired up (and after that, making sure I can run it properly)---but I know that you all are up to it. (: Wish me luck. ok r.

Hard drive adapters

by allisonp＠world.std.com

< Does anyone out there know of some sort of gizmo that could be made tha < would convert an old RLL or MFM Hard drive to be used with a parallel < interface? I've seen then for IDE, but that's it. I've got a couple o < old HD's laying around that I'd like to put to use, but there's no room < any of my computers to put them. Parallel interface on what? PCs are the only ones you can count on for a consistant (sorta) interface. Few others are similar. To go from parallel (assuming it's bidirectional) you would need something like a WD1002HDO adaptor and some custom logic and software. VERY NON TRIVIAL! It would be a fair amount of proframming effort and hhardware to pull it together. < By the way, does anyone have any old Apple or TRS-80 external disk drive < that they'd want to get rid of for a few bucks? I don't need the drive < itself. I need the case and power supply and that's it. If they're < TRS-80, I could use the drive itself, too. Apple and trs80 drives are not interchangeable though the case/PS would be. I think I still have one with a drive. Allison

Which track was least reliable?

by peacock＠simconv.com

> "On disk platters," he said, "the inside track > is the least reliable one." > This was true when drives were formatted with the same number of sectors on each track, regardless of position. Because the inner tracks had a shorter circumference, the bit density was highest on the innermost track. Now that drives are not directly addressed by cylinder/head/sector, the number of sectors can vary by track, so bit density is evenly distributed, outer tracks have more sectors than inner tracks. Where you see this limitation was on older MFM and RLL drives where the controller was not integrated onto the drive itself (pre-SCSI and pre-IDE). Jack Peacock

Shame, shame, shame

by peacock＠simconv.com

>However, as a sysadmin, every so often I feel the primal urge to "get even" with the machines that are a constant pain in my arse. Disassembling a semi-functional Wang PC with a splitting maul is very cathartic when things get to that point. Does anyone still have that classic cover from an early issue of Interface Age? The one where the programmer has just buried a fire axe in an ASR-33 teletype. That's one every TTY user can identify with, watching your listing slowly crawl across the page at 10 CPS. Jack Peacock
