Oh, God, I feel another song coming on... But instead, yeah, Louisville KY metro area. Third World. Ten years ago, in a Wendy's, this guy comes in looking enough like Li'l Abner (plaid shirt, bluejeans w/rolled- up cuffs and bare feet) that I had to check to make sure that a Dogpatch musical wasn't playing... it wasn't, this guy had never heard that you can't enter a restaurant with bare feet. Most people with tech skills leave for better opportunities on the left coast. In the music scene, "The Louisville Sound" is the sound of a 727 taking our musicians to L.A. A major local issue is the destruction of roads by steel- wheeled tractors. They're not just for Amish, you know. And the cable company will be the only provider of "the last mile" to my subdivision for at least the next 5 years. I'm 19473 feet away from my CO, so unless a new technology gets deployed, I'll be on 56k dialup for the forseeable future. That ain't smoke signals or talking drums, but it ain't really high tech anymore, either. Regards, -dq

Trinary circuits

by mtapley＠swri.edu

Iggy et al., > This might interest some of <you> out there: http://www.trinary.cc/ Yep. Interestingly there is an alternate formulation known as the *Balanced* trinary number system. (One of the folks around here wants to label it "BaTeNuS".) The idea is that the digits, rather than being 0, 1, 2 for each place value, are (-1), 0, 1, meaning subtract, don't do either, or add the place value in which that digit appears. For convenience I'll write (-1) as "n" below, though in (LaPlace's?) original work it was written as 1 with an overstrike. Decimal Batenus Explanation ... -9 n00 (-1) * 3^2 + 0 + 0 -8 n01 (-1) * 3^2 + 0 + 1 * 3^0 -7 n1n (-1) * 3^2 + 1 * 3^1 + (-1) * 3^0 -6 n10 (-1) * 3^2 + 1 * 3^1 + 0 -5 n11 (-1) * 3^2 + 1 * 3^1 + 1 * 3^0 -4 nn 0 + (-1) * 3^1 + (-1) * 3^0 -3 n0 0 + (-1) * 3^1 + 0 -2 n1 0 + (-1) * 3^1 + 1 * 3^0 -1 n 0 + 0 + (-1) * 3^0 0 0 0 + 0 + 0 1 1 0 + 0 + 1 * 3^0 2 1n 0 + 1 * 3^1 + (-1) * 3^0 3 10 0 + 1 * 3^1 + 0 4 11 0 + 1 * 3^1 + 1 * 3^0 5 1nn 1 * 3^2 + (-1) * 3^1 + (-1) * 3^0 6 1n0 1 * 3^2 + (-1) * 3^1 + 0 7 1n1 1 * 3^2 + (-1) * 3^1 + 1 * 3^0 ... you get the idea. Notice that negative numbers are built in - no need for an additional (-) symbol leading a number. Also notice that to negate a number, you just negate each digit. Fractions, addition tables, etc. are left as an exercise for the reader. This system is great if you have a balance beam and want a minimum number of known weights. To get an (n), you put a known weight on the same side as the object being weighed, while to get a (1), put that weight on the opposite side. With 4 weights, (27, 9, 3, 1) you can generate every integer weight from -40 to 40 - try that with a decimal set of weights (or binary, for that matter). The problem I see with putting either Batenus or trinary in silicon (or gallium arsenide, etc.) is that all the electric technologies I know of are fundamentally binary. On/off, charge stored vs. not stored, current flowing vs. not flowing, etc. You need two binary bits (4 states) to hold a trinary digit (3 states), so there's a 33% loss. Even ignoring this, you only get a 50% increase in information capability and processing speed at best. Would you rather rebuild your computers from the gate level up, including all of the software, or just wait 6 months for the semiconductor industry to get you the 50% speedup in binary? However, I do notice that SQUID circuits, and some other superconducting phenomena, might well be made to work in a trinary fashion (no current, current circulating left, current circulating right). If so, that might make Batenus or trinary pretty interesting again. Am I Off-topic if I'm 10 years into the future? :-) - Mark Linc, >Calculating in binary code is as easy as 01,10,11. Calculating in Batenus is as easy as 1,1n,10

I've got it running on the WGS8150/80 sitting behind me. But Cyberdog could well rise again, under Windows... As you know, Cyberdog was essentially a container for a series of net-enabled OpenDoc components. While Microsoft has still never released the OpenDoc-killing Cairo OS they'd promised, Apple and IBM did stop development of OpenDoc; meantime, Micro- soft continued to develop the Component Object model enough that a certain third-party is going to take advantage of it big-time. The party is Stardock, and the product is DesktopX. The next generation of DesktopX will provide a framework for the use and development of COM objects directly by the user. With DesktopX, it'll be almost trivial to recreate Cyberdog using COM (and ActiveX components) instead of OpenDoc. I'll stop there since I'm drifting OT... -dq

Altair32 Update - 11/22/01

by rcini＠optonline.net

Hello, all: I got another disk image working -- AltairDOS. And again, I have no manuals so I'm running a bit blind. This image seems to boot to a monitor program and a dot prompt. Does anyone have a command list to go with this? I've also gotten some error codes, so I probably need the whole manual. Also, I'm having a bit of a tough time...because of the configuration of the images I'm using, the status bits returned from the console are the exact opposite of a BASIC implementation. So with the emulator one could use *either* BASIC tapes *or* CP/M for example. So, I'd like to put out a call for someone with the code for a CP/M 2.2 BIOS for an Altair with the MITS floppy controller and an SIO or 2SIO serial card. Also, I'm going to need a layout of the floppy format because I will probably have to write some disk image manipulation tools for Windows so that I can regenerate a bootable CP/M image (straight T/S increments). On a positive note, I was able to get the integrated debugger that I borrowed from Jim Battle's Solace project working. This will prove to be a big help later on. Thanks Jim! Again, any help from those with a real Altair is greatly appreciated.

Price guide for vintage computers

Hate to prolong this already too-long thread, but that raises an interesting point; since that's exactly what most of us were doing in those long-ago days, hacking around the insides with our soldering irons, is it really a sin to do the same thing today instead of keeping them on the shelf in pristine condition?

New find : AT&T Unix PC7300

I was given this today. It has a tape backup (and controler board) and the DOS-73 "emulation" board w/ 8087 upgrade (but no 8088... are those NCR chips 8088 clones?). Included is full system software and docs. I wonder if the 5.25 inch disks are still readable. The computer is slightly dirty on the outside and dusty inside (on the expansion boards). I think I'll wait untill i can dust out the insides a bit before powering it. So now I have a Real UNIX(tm) computer! heh. -Philip

Yeah, the keyboard cable is supposed to be straight pinned (or was that cross pinned... no it was straight pinned). A standard phone cable is cross pinned (or was that straight pinned... no was cross pinned... LOL). If you use a standard phone cable, you will fry the keyboard controller chip. I am sure that was the snap you heard. You can always use the mouse and the Key Caps desk accessory, type by clicking the letters, then choose cut and paste to move it to whatever you are trying to type in...

I came across a stash of HardCard driver diskettes today (360K 5.25"). They say on the label that they are for the 20MB version, but I'm sure they would work on the 40MB model as well.

That's a pity. They weren't always like that; the Apple ][ service manuals included complete schematics and diagnostic software, and the service centre package included quite a lot of component spares (though I think we bought those separately, not with the service manuals). I suppose it's not surprising they included the schematics, since some were in the normal user manuals anyway, but the service manual had more information. They were always a bit funny about people doing repairs, though, even out of warranty. We were part of an education auhority, not a comercial service centre, so perhaps that made a difference -- but we didn't find the local Apple Centre much good at that. -- Pete Peter Turnbull Network Manager University of York

Mac SE Sigma Video Card

by mythtech＠Mac.com

I just aquired a Mac SE FDHD (thanks Dave!), and it has a Sigma Designs video card in it. Surprise Surprise, ANOTHER company that seems to deny that they ever made things for the older macs. Needless to say, I can't find much info on it. It is part number 52-000132. It has a DB-9 Female connector for the monitor. Anyone know A: if drivers are needed (probably) and where I might get such (they might be on the computer still, I didn't have anymore space to boot it, nor another keyboard/mouse on hand... so I just opened it on the floor to have a looksee). B: What kind of monitor it connects to? (looks like a CGA or EGA connector, but could be just about anything... from what I am finding Sigma offered a cool SCSI based monitor that had its own custom stuff, so I am fearing that it needed a custom monitor too) C: What kind of video it is... that is, color, greyscale, monochrome... bit depth (if not monochrome), what size it could drive, output freqs... whatever.

Another Old-computer dealer.

by mtapley＠swri.edu

All, Located another dealer (Mike Hancock) of old computer parts in S. Central Texas, this one in San Antonio. This is of interest to me, because this is where SwRI's cast-offs go, so there is likely to be some *unique* equipment there. http://www.ctbicompany.com I think he has the same general M.O. as the previous place I found; that is to say, he gets a *lot* of stuff, filters out and saves what he thinks he can sell, then scraps the rest. I have not seen his warehouse. Have we developed a clear, easy-to-use "wanted" list or website for this group? It'd be neat to be able to hand this guy (Mike Hancock) or other dealers the list or URL, and tell them if they see something on the list, save it, it's worth $xxx. Could we set up a database/bid deal, where anyone can add to the list of "want" items, and what they'd pay for it? - Mark

OT: paging MAC expert(s) --- What's a Performa?

I believe there was at least one MS-DOS browser that didn't (doesn't) require a _separate_ stack. That is, since it is built into the browser. There is also slipknot(slipnot?), which acts as a front-end to a shell-account with lynx. :) (That's an interesting program...)

Mac Restore CDs/Manuals

by mythtech＠Mac.com

>I assume these are boardswapper guides and don't include useful >information like schematics, right? Exactly. They are wonderful when you are trying to do things like open a Powerbook to repair the latch spring or the mouse button (both things that are prone to break on the 190/5300/3400/G3 case design), but totally useless if you want to know how to repair the fried power supply on a 1400 (swapping yes, repairing no). But that jives with apple and the Mac... they have ALWAYS had a board swap approach to repair. Even when the repair is something simple. So if that is all they approve doing, why bother making public (or in the case of these, pseudo public) manuals that cover anything more detailed. I would LOVE to find another good book on actually repairing Macs (The Dead Mac Scrolls was wonderful, but it only covers thru the II IIRC... I want something that will tell me how to get my PB 1400s power supply working again, or repair/replace the fried printer port on my 6500... that is the kind of book I want to find) >Now, I guess I've come to expect that computer service centres can't >trace a fault in a circuit of 4 components. But if they're going to >board-swap, shouldn't they just swap the defective board? And not also >replace an expensive PSU that's got nothing wrong with it? I know around here, it is very hard to find a "decent" repair shop. That is, one that knows what they are doing, won't try to rip you off, and can do economical repairs. For a while, the local CompUSA (big national computer retail chain for those not in the US), had a GREAT tech. He could do component level repairs, and did them on a regular basis. It was not unusual to take a computer in, and find that it was repaired for the diagnostic fee ($65), plus a dollar or two in parts.... guess what... the CompUSA fired the guy... why? Because they could make more money selling new boards then repairing the broken ones. They looked at it in terms of, they can make no markup on a 50 cent transistor, and no additional labor for the guy to spend 5 minutes replacing it... OR, they can make a 20-30% markup on a new motherboard, AND 2 hours of labor (@ $65/hr) for the tech to replace it, and reset the windows installation to accept it... AND they could use brain dead, no training people at $10/hr to do the work (compared to I am sure a much higher rate for the guy that knew what he was doing). And then you just have apple, that doesn't authorize "custom" repairs on its parts... if it is warranty, or an "authorized" apple repair, it is done as a board swap, and only to the detail they specify (which in many cases means far more gets replaced then needed)... the tech mentioned above used to ask, do you want an apple authorized repair (needed if it was warranty, or you wanted to maintain a warranty if the repair itself isn't covered), or did you want an unauthorized, but cheaper and faster repair. Most people I know took the unauthorized repair for all units out of warranty (can't void what you don't have) -chris <http://www.mythtech.net>

Actually, there are tech manuals that give breakdown and assembly, and part numbers for almost every mac, and apple product. They also include basic diagnostic. I believe they are the same manuals the apple authorized repair centers use (which is really sad, since the diagnostics are pathetically simple, so obviously apple doesn't expect their techs to have much of a brain) You can download the manuals from an Apple FTP site, the catch is however, you can't browse the contents of the ftp directory, so you need to know what the manual is you are after. Fortuantly, someone has put up a web site listing many of them (and links to the FTP site for easy download). The web site WAS: <http://www.accesscom.com/~gamba/manuals2.html>, alas as of just checking it now, it seems to be gone. Maybe someone will know a newer site? (thankfully I pulled down copies of everything I own or am after... now I just wish I had taken the time to pull everything available down) -chris <http://www.mythtech.net>

Remington Rand 409-2/2R

by egendorf＠mit.edu

Hi! I am helping to gather original documents and/or artifacts concerning the Remington Rand 409-series computers for the Remington Rand museum being set up in Rowayton, CT. The models of interest are the 409-2 and the 409-2R. We are interested in documenting the location of all surviving artifacts, but also would like to acquire particularly interesting items by donation or purchase. If you have any original documents or artifacts (even as minor as Remington Rand brand punch cards), please e-mail me at: egendorf(a)mit.edu. Thanks.

I knew he had some trouble originally. From the story I heard (well, peiced together), he originally was hosting the manuals directly. Apple complained, so he changed the links to their servers. I figured if Apple complained once, it was only a matter of time before he was shut down entirely. Thanks for the new link... this time I was smart enough to save the page locally, so I can stick it on my web site. I think I will take some time next week to just start pulling all the manuals down (CD-Rs are such a wonderful thing) -chris <http://www.mythtech.net>

Toshiba disk & DSDD floppy

by mythtech＠Mac.com

>DSDD 3.5 drives are rare too, as most dealers threw them away. I have a >small stash, but I'm haning on to them as they are used in Amigas. I have one DSDD 3.5" drive (720k drive). I *think* it works. It is a standard size 3.5" drive, but the face plate is part of the unit, and it is for a 5.25" hole, so you really need a 5.25 half height bay to fit it. I don't really need it if someone was on the search for one (sorry, missed the beginning of this thread) -chris <http://www.mythtech.net>

50th anniversary of the routine business use of computers

by Robert_Feldman＠jdedwards.com

I was looking at the Economist (Nov 17th) at the library last night and saw the following (p. 76) The Lyons Electronic Office (LEO) began use 11-17-1951 in a British catering company. It was used weekly to evaluate costs, prices, and margins for the week's output of bread, cakes, and pies. It was "the first dedicated business machine to operate on the 'stored program' principle, meaning that it could be quickly reconfigured to preform different tasks by loading a new program. It occupied 5,000 square feet of floorspace, contained 6,000 thermionic valves, and its mercury-delay-line memory could hold 2,048 instructions. LEO was built by a team led by John Pinkerton (pictured), and its design was based on Cambridge University's EDSAC computer."

I assume they exist somewhere, but the closest thing I've ever seen to a tech reference or service manual for any macintosh was the Chilton's book on macintosh repair. (Yes, the same people who do automobile repair books...) It have that book, and it's relatively decent.
