Mystery (RE: Altair prices)

Who Bought It (RE: Altair prices)

by peacock＠simconv.com

>But did she actually buy it? She placed her bid 6 mins before the close of the auction when the high bid was only $3000. Right at the end of the action, someone else placed a $12000 bid forcing her bid to $12100 and the reserve still hadn't been met! In casinos it is a common practice to have employees sit at card tables and play conservatively to fill out the card table till enough regular players are seated. This is so the games (usually poker) can continue if there aren't enough real players to make it interesting. This is a legal practice (here in Nevada) but their playing is limited and they must leave the table as soon as enough players are there. They are called "shills". There is also a type of shill in auctions. They are usually friends of the auctioneer and are briefed beforehand to make a minimum bid on certain items, to ensure the item does not go for too low a price. The auctioneer doesn't sell to the shill, just puts it back for another day. In this case the legality is dubious. Caveat Emptor, it appears shills are at work on E-bay (I'm shocked, shocked to discover price rigging!) Jack Peacock

Here is the purchaser. NOT what I would have expected! http://www.lne.com/lemay/ OK, pop quiz before you look at this site. Which of the following did you think just paid $12,000 for an Altair? A) A 60-year-old ex-Byte Shop manager B) A retired aerospace engineer and ham radio operator with nothing else to spend his money on C) A Ferrari-driving vested-option veteran of a huge software company D) A museum curator E) An antique dealer/speculator F) A 30-year-old female author with a nose piercing Kai -----Original Message----- From: D.

I haven't looked at the URL but I'm sure I don't know anyone involved. It IS depressing, isn't it? I've been thinking about this aspect of computer collecting for a while. Someone on alt.folklore.computers said that he had verified the authenticity of an Apple I system (complete with original cover letter receipt signed by Steve Jobs, etc.) just before it was shipped across the country to a new buyer. As I drooled over this, I realized that it's an extremely desirable thing to have (and this one in particular sounded rare) but the economics are just too warped. There are only a handful of these machines, right? And they just change hands and the prices go up. Also, it may be desirable to have, but not to USE. The RAM is expandable to almost 64K (though I've never heard of this being done) but there's only one slot and the only card built for it was a cassette interface. The display is slow because it uses a shift register. I'm just too practical, I guess. I believe in collecting things to use them/ have fun with them, and the rarity of the Apple I is at odds with this goal. I too have to wonder at the motives of the buyer of this Altair. There IS the possibility that this is an elaborate "sour grapes" argument, given that I have neither an Apple I nor an Altair. :) -- Derek

> $12100 for the world's flakiest S-100 box: I've just been dumbstruck dead. Did you look at the card list? It has one of the old Ithaca Audio CPU cards in it. The early IA Z80 cards were a poor second choice to a Cromemco card, but probably a step up from the original TDL Z80 card (that was the first Z80 CPU out). I had one of the IA cards, threw it away when they switched to Ithaca Intersystems and started making real class boxes and boards, got one of the XPU cards instead. Those were nice, 20 bit memory addressing with an MMU, very stable, it's what I use in my IMSAI now. And not even original MITS memory to go with it! Now if it had a working (!) 4K dynamic MITS RAM board I would be impressed. That was a truly rare commodity, because of design flaws the memory usually didn't (remember, that is). Jack Peacock

Lisa battery leakage??

by dastar＠ncal.verio.com

Ok, what are all you other Lisa owners talking about? I pulled my Lisa down to check to make sure the batteries haven't spilled out all over the place and didn't find any anywhere, and niether did I find any terminals where batteries would go. I've had this for 6 years now, and last year I featured it in the VCF exhibition and it booted right up, so it makes sense that I don't have a bettery leakage problem, but I'm wondering what other people have in theirs? Maybe mine is a later model Lisa with a different motherboard. Sam Alternate e-mail: dastar(a)siconic.com ------------------------------------------------------------------------------- Ever onward.

< >believe it was also available for the IBM PC, PDP11, Sage, etc. I've run it on Apple][, NS* Horizon(z80), and PDP-11/23 and all worked the same and fairly well though a bit slow. it was honest pascal and I used it to teach many people the language. < As for Sam's childhood trauma disk injury, should we discuss < which systems didn't have a hardware-based "disk changed" indicator, < and which relied on software methods to prevent that sort < of disaster? All of the systems I used DIDNOT have disk change logic, nor was it needed. the P-system does volcheck on a disk before writing or reading to make sure it's the right one. Likely the volume was of the same name or the kernel was corrupted. I know this as the NS* was only 80k per drive and three drives and I'd often put the wrong disk where ever. Also Most version had dupdir so if one directory was munged you could copy the other and use it. Allison

UCSD Pascal's directory structure is absolutely elementary. It's FAT has room for a fixed number of files, and each is stored contiguously in logical blocks. If you've still got the disk, you can easily recover your files. I'm not sure why it would decide to zap the directory structure - are you sure it wasn't your fault? :-) There's a volume label, and I thought the OS at least checked this before it assumed the right disk was in the drive - unless your program was working at a low level, and asked for a specific (#4:, #5:) drive. - John

Free 11/04 System

by jpl15＠netcom.com

S'funny. I thought there might be more interest in a working PDP system, because everyone complains there are (relatively) fewer of them left in the Southern California area. So just a reminder to my esteemed ListDwellers.. I have a big 11/04 system that is free to a good home, details can be read in the archives under a siliar heading, or e-mail me for details. If there is no interest, I must part out the system to make room for Other DEC Stuff. And also, Thanks to all who have written with advice to my last round of novice system config questions.

Philips XT with 768K

by pb0aia＠iaehv.nl

It is not a BIOS trick. The extra 128K appears in the upper memory area, >from D000 to EFFF. There was a special device driver available, USE!UMBS.SYS, that turned this memory into UMB's if you were running DOS 5. Great for parking mouse and network drivers in. The driver was written by a hobbyist as a memory study project, it was available with the machine code source so you could modify it for other computers. IIRC it should be on Simtel. I also have a copy around here somewhere. I used to admin a network that had lots of Philips XTs, NMS9100 and P3105 were the ones that had this extra memory.

Quick question: what's a DEC DS200? (I'm assuming it means DECstation 200, but I'm also guessing it's x86-based and has no relation to the larger MIPS-based systems). Another question: what would be a reasonable offer for a stripped DECsystem 5500? The guy seems to want a (IMHO) ridiculous price for it (somewhere around US$900 as far as I can tell). He seems to think he can sell it to someone that will use it to it's full potential, pitting it against modern high-end machines. My offer, needless to say, was no where near what he wanted! From what I can tell the DS5500 would be not much more than a rare novelty (it IS a Qbus-based MIPS, after all), let alone a competitor to modern servers.

Denver finds

by sinasohn＠ricochet.net

Well, all I can say is if you're going to Denver from San Francisco, (or vice-versa,) fly. We spent 24 hours getting there, with only food/bathroom stops, and a 1/2hr nap somewhere in Nevada. 8^) Anyway, We went to the Mile High Flea Market which turned up a Magnavox Odyssey 2 (+ 7 games) and 2 APF TV Fun machines. (And some Fisher-Price cars/people.) Then we hit a number of thrift shops where we found 2 different versions of a VTL/VTech learning computer, ca. 1980+ (I already had one, the oldest of the three.) We also came up with another Odyssey 2, an Alphie II (learning toy in the shape of a robot), and an Atari Pong game in the box. We passed up an NEC APC (vt-100 like machine, with 2 8" floppies,) a Commodore PC-20 III, Franklin Ace 1000, and a few others at the ARC about 10000 E. Colfax, and an Amstrad PCW 8256 at the ARC on Florida and S. Broadway. The keyboard and main unit were there, but separated, I reunited them and told the guy to keep them together. The last one we stopped at, on the way out of town was on W. 74th(?) near Wadsworth. There we left behind an apollo monitor (labelled "Domain") and a PCjr Monitor. What we did get was an IBM 5155(? The suitcase one) and a TI ProLite laptop, with powersupply and "drive box" (additional disk drive that attaches to the back.) The former was marked at $12.99 and the latter was $24.99. I took them up to pay and asked the gal if she could reduce the price on the TI (it never hurts to ask!). She called the guy from the furniture department (computers are furniture, btw) and asked him. He looked at what I had, crossed out the price on the TI and wrote "2pc" on both computers. I got 'em both for $12.99. We also got, over the course of the week, about a dozen pairs of tap shoes, but not much Donald Duck stuff. Anyway, if you're in the area, you should keep any eye on the ARC stores. They seem to get a lot of stuff, and regularly have 1/2 price or even $.99 sales. --------------------------------------------------------------------- O- Uncle Roger "There is pleasure pure in being mad roger(a)sinasohn.com that none but madmen know."

DECserver

by afritz＠delphid.ml.org

Well, I got bored tonight and pulled out a DECserver 200/MC that somehow ended up with many months ago. First thing was take a scredriver to it (it was quite noisy and I figured I should probably figure out what the obstruction was). Well, the obstruction was, well, dust. Although I'm not writing this message to talk solely about dust, this was some interesting stuff. From the looks of it either this thing had been in/near a fire or it's administrator smoked at an unhealthy rate. Very black and very plentiful. Also very difficult to remove (extremely fine). Removing most of it made it quieter. Anyway, what can I do with this thing? I don't have the boot images for VMS, nor do I currently have a running VMS machine. When I turn it on, the D1 light turns on, followed shortly by the D2 light, and the D3 flashes when it's transmiting. And there's MOP packets on the ether, so I must assume it's in working order. Eventually, the D3 light starts flashing constantly and D4 starts flashing every half-minute or so. I don't suppose there's any way to do IP, is there? One thing I was suprised to see in there was the face of a big original package 68k. It might be interesting to write a custom boot image. :) In any case, does anyone have a copy of the boot image for when I get a VMS machine back to being functional again? af ------------------------------------------------------------------------------- Adam Fritzler | afritz(a)delphid.ml.org | Animals who are not penguins can afritz(a)iname.com | can only wish they were. http://delphid.ml.org/~afritz/ | -- Chicago Reader http://www.pst.com/ | 15 Oct 1982 -------------------------------------------------------------------------------

Warning: Teac FD-55BV-16-U

by healyzh＠ix.netcom.com

I thought I'd put out a warning about the Teac FD-55BV-16-U 5.25" floppy drives. They seem to be totally unsuited for anything other than reading MS-DOS floppies. I bought one a couple months ago, for a project with my Amiga, since they were what the developers of the Catweasel board recommended. Spent about two days trying to get it to work. Finally I pulled the drive out of my 486 (an older Teac drive) and it worked immediatly. Assuming the Amiga part of the equation was the problem I put the new drive in the 486. Well, yesterday I needed to make archival images of some RX50's. No dice, it absolutly would not read them. I'd picked up some older Teac's at the last swap meet, so I got them out, and after two that only semi worked I found one that works just fine, and was able to make my images, copy them back to new floppies, and boot my PDP-11/73 off of them. Note, I tried using the Teac FD-55BV-16-U drive with both 'putr' and 'teledisk'. Neather would work with it. Zane | Zane H.

Another choice is a '125. A '242, '243 only have the data inverted from each other, so if one's the correct chip, the other won't cause logic conflicts, just wrong polarity signals. -Dave

PDP-11 Update

by healyzh＠ix.netcom.com

Well, thanks to the answers I got on my questions I've got a bit better of an idea on how to proceed with getting the newly built from parts /23 up and running, and I understand why I was having difficulties (as I thought, the path through the backplane). Since I'm using a RQDX3 for the drive controller, it sounds like my best bet is to forget the RX50, and go straight to RX33 drives. However, based on my taking an additional look at the RX50 drives I'll probably try to get them up and running. What can I say, they're just too cool looking :^) The QD614 board for emulating RL01/02's sounds pretty cool, to bad I don't have the software for formating the attached drives. Zane | Zane H.

Why not just run... What's that DOS program that fakes out apps to make them think they are running on another version of DOS?

Plus/4 Power Supplies

No, that's NOT what I said, to make it easier to understand: 1. remove the round PC mount power socket from a dead 64 curcuitboard 2. remove the Plus/4's square power socket from the Plus/4 curcuitboard 3. solder in the 64 socket where the Plus/4 socket was (the pin locations are the same) Then plug in any 64 power supply to the Plus/4 and fire it up.

1.2Mb floppy as RX-50?

by healyzh＠ix.netcom.com

I don't really trust the one RX-50 drive I've got, and I seem to recall that it is possible to hook up a 1.2Mb floppy from a PC drive as 1/2 of a RX-50 drive. Is there anything special that needs to be done, or do I just plug it in? Zane | Zane H.

Q-Bus 18-Bit to 22-Bit wirewrap?

by mbg＠world.std.com

Please pardon if this has already been answered... I've been away for a week at the Worldcon (world science fiction convention) >I have a really compact "PDP-11/23S" chassis that has an 18-bit Q-Bus >backplane (4xQuad) in it. Although the circuitry for the Q-Bus is on >traces of a PC card, there are also wirewrap pins extending out from >the backplane. Am I naive to assume that I can convert this to a >22-bit Q-Bus by wirewrapping four or so lines? Any pointers on how to >do this or on technique? Not naive at all... I've done it on at least one of my H9270 backplanes at home... I know of many others who have as well. If I remember correctly, you need to buss the BC-BF lines (and for Q-Q backplanes, DC-DF), but I would have to verify this...

Dunno the CSR), it should work fine. It needs a different PROM to switch the address/vector. The standard PROM at U38 is labelled 91265D (according to my old notes) and the alternate-address PROM is labelled 91578A (old notes again). YMMV :-) > > What kind of Hard Drives will work with it? > > The one I have used to have a Rodime 10 Mb 5.25" full-height MFM drive > attached to it. I'd love to hear if an ST-251 would work. Again, it should. It should be capable of using up to two ST-412 interface drives to emulate up to four RL02s, though I never tried mine with more than one. IIRC there's a small overhead, so you need slightly more than 20MB to emulate two drives. > > Is there any kind of setup for it?

It would use the regular DL boot ROM on your system. It does have a bootstrap, but I think the emulation is RLV11 (it's to old to be RLV12, I think). You can switch the bootstrap off, though. The code will boot either a DY or DL device. > > Any idea on how well it would co-exist with a DQ606? > > No idea. Me neither. I don't have the full docs, just a pair of layout diagrams, switch table, and a few bits about formatting. Unfortnately, all the formatting stuff seems to use a program which I don't think I have handy. At the back end of the board is either a 34+20 pin connector, or two individual headers. As Ethan said, the 34-way is the control bus (daisy-chained like floppies for multiple drives) and the 20-way is the data. J3 is the second 20-pin data connector (for the second physical drive). Pin 1 of the 34-way connector is the end nearest the LED, and the other connectors are fitted in the same orientation. There are five switches: S1 ON = ECC used to transparently correct errors where possible OFF = ECC ignored; used for diagnostics S2 ON = bootstrap enabled OFF = bootstrap disabled S3,S4 Identify the last logical RL unit on physical drive 0. So the settings are as follows: S3 S4 Physical 0 Physical 1 off off DL0 Dl1, DL2, DL3 off on DL0, DL1 DL2, DL3 on off DL0, DL1, DL2 DL3 on on DL0, DL1, DL2, DL3 S5 ON = use secondary address for bootstrap ROM: 175000 OFF = use primary address for bootstrap ROM: 173000 Factory setting is all switches off. There are 10 jumpers: JP1 (near U22) removed (etch cut) allows data loopback for diagnostics. JP2 (near U32) removed (etch cut) aborts controller pre-comp logic when writing, for diagnostics. JP3,4,5 (near U70) sets interrupt levels: level JP3 JP4 JP5 4 B-C B-C B-C 5 B-C B-C A-B 6 B-C A-B B-C 7 A-B A-B B-C JP6 (near U22) "Must be removed" JP7 (near U22) "Must be removed" JP8 (near U5) "Must be removed" JP9 (near U32) "Must be installed" JP (near U32) "A-B must be installed, A-C must be removed" There's also a socket for a special (customer) bootstrap at U38. That's about all I can tell you, I'm afraid. I'll have a look for a copy of the formatting program (which came on an RT11 floppy, I think) but I'm not hopeful... I don't have the controller any longer. -- Pete Peter Turnbull Dept. of Computer Science University of York

Tandy 1000 HX

by higginbo＠netpath.net

I saw a Tandy 1000 HX at a local once a year flea market friday and was wondering if the expansion cards it uses (non-standard) are hard to come by. I'd like to get it and use it as a dial-in terminal with either a 300 or 1200 baud modem, whatever is available. This is one of the one-piece 1000s, and there's no RS-232 port, or DIN serial port connector on it, just joysticks, ext. floppy, and printer connector, the last two are edge-type connectors. Maybe I'll pick it up tomorrow. I love these yearly Hospice Flea Markets: Everything starts off at full price, Friday and Saturday. Sunday, all the prices drop by 50%, Monday, you give them a few bucks, and they'll let you cart off anything that is left. I hope the tradition still stands this year. I saw a Timex Sinclair 1000 (black, mebrane keyboard) along with some cassettes and mem expansion boxes for $5.00. If it's still there, I might pick it up if someone wants it. (What?!? He's not putting it on ebay to get $500.00 bucks for it? Is he crazy???) Yes I are! - - john higginbotham ____________________________ - webmaster www.pntprinting.com - - limbo limbo.netpath.net -

Altair prices!

by altair8800＠hotmail.com

No, I'm not talking about Ebay prices. Instead I thought you might be interested in seeing an original Altair Price list >from July,1976. Here's the link to a jpeg of it... http://home.att.net/~rwood54741/25.jpg We have heard that the 680 was a failure because the 16k memory card for it cost more than the computer. Take a look at this list and you will see it in black and white. The 680 computer kit cost $466 ($625 assembled). The 16K memory card cost a staggering $685 as a kit and $865 assembled. That is a whopping $43 per 1k of memory. Bob Wood ______________________________________________________ Get Your Private, Free Email at http://www.hotmail.com

DQ614 and other Q-Bus questions

by healyzh＠ix.netcom.com

Hmmmm, now this sounds ponentially very cool! According to the Field Guide this is a "Dilog ST-506 emulation of four RL01/02". Any one have info on this, and will it work in a system that has actually RL02 drives attached? It would make it a lot easier to get data on to the Hard Drive if I can just copy it from a RL02 to a fake RL02. What kind of Hard Drives will work with it? Is there any kind of setup for it? There is a funky 20-pin connecter marked J3 that might be for jumpers or a ribbon cable though I don't really want to try to attach a ribbon cable to it, as it's rather wierdly attached. Does it have any kind of boot ROMs? Any idea on how well it would co-exist with a DQ606? How well do Boards with Boot ROMs co-exist with systems with another set of Boot ROMs? I'm threatening to throw the DQ606 in the 11/23 that I'm working on, so I can access the rack of drives that go with the controller. Well, I'm off to work on archiving some RX-50 floppies prior to actually trying to use them. Hopefully they're readable! So this should be a break in my steady stream of questions :^) Zane | Zane H.

Wyse terminal modes

by afritz＠delphid.ml.org

This is probably not a 10yr thing, but I don't know any other list that's got this many people that know what they're talking about... I've got a Wyse WY-50 terminal. From the menus, it's got four modes: FDX, BLOCK, HDX, H-BLK After reading (on this list) that the old HP terminals had something called "block mode", I was wondering what it meant here. Also, what's FDX and HDX? The first thing that came to my mind was Full Duplex and Half Duplex, but I don't know how those would apply. Also, are these terminals just really lacking features or are Linux and *BSD just not running it right? It seems that tabs get ignored, for one. And it is just generally awkward looking. (And the arrow keys don't work in pine, but that's not terribly critical.) It doesn't act in a logical way at times. What were these terminals meant to be used with? I got this one from a AS/400 installation, though I don't know if it was ever actually used for the AS/400 (they had a whole mess of IBM twin-ax terminals for that). af ------------------------------------------------------------------------------- Adam Fritzler | afritz(a)delphid.ml.org | Animals who are not penguins can afritz(a)iname.com | can only wish they were. http://delphid.ml.org/~afritz/ | -- Chicago Reader http://www.pst.com/ | 15 Oct 1982 -------------------------------------------------------------------------------

SMD Interface Drives

by karlm＠blitzen.canberra.edu.au

Hi Again, The Sun currently has 2x Fujitsu M2322K drives which appear to be SMD interface drives (on a xylogics 451 controller), is there any way to interface ohter kinds of drives into this interface? Also, I spotted an Apple IIGS for sale in a second-hand place down here, it looked complete but it was labelled "parts only". I asked why and the response was "It doesn't have a startup card", I assume this means disk. They want AUS$60 for it, I was thinking about offering them AUS$30, is this reasonable?
