Hi Toth, I saw your demand for any Parts of the uA78MGU1C. I have a few of them. 10 or 20 pieces. Are you interessted ? Keep in touch Oliver Your Demand from Thu Dec 19 08:04:13 2002 I've been looking for a replacement uA79MG negative voltage regulator for awhile, but so far haven't been able to find one. It is for a custom power supply for an embedded system made in the early 1980s. Fairchild's part number for the device is uA79MGU1C, which they call a 'Power Watt' package. It actually looks like a TO-220, but has 4 leads. The regulator bolts to a heat sink on the supply's board. I need at least one of these parts, but could use a spare or two if someone has a bunch hiding away in their parts cabinet. I could also use a couple spare uA78MG (uA78MGU1C) regulators too, but they would just be put away as spares for these power supplies. -Toth

Mac G5 / Moving to OS X

by sml49＠comcast.net

> Hi Seth, > > I'm curious if you bought those upgrades new, and what they cost? > > --tnx > --tom Tom.. The G3/800 was about $298. The Maxtor 200 was $199 after a rebate, the Acard controller around $86 and the Radeon 7000 another $105 and the Lite-On 526 around $40 over the counter locally so around $725 or so total. I had done this incrementally - I needed a larger faster drive long before I decided to go to OS X. And yes, to respond to another poster, the machine would indeed run OS X w/out all this and in fact it did for awhile but it wasn't as responsive as I'd have liked. I bought the Radeon - it's the fastest non-AGP one - with the idea that I would be able to move up at some point to a large digital LCD display; my old FD Trinitron is showing signs of age and I don't figure on buying any further CRT displays. This is my mainstream machine, the one I keep my digital life on so I pamper it; besides, I like it's blue front panel :-). Its FireWire ports are a little funky - all Blue G3's are reputed to have flaky FireWire - so a few years ago I put an Adaptec PCI FW card in there; found it on the discount table at the local Micro Center. There's also the dozen or so assorted older 68000 and early PPC Macs I have around here, most working and a handful of them online. My source of supply is the local town disposal area; very fruitful. Need a Iisi or two? A small to medium sized SCSI drive? I've got a few tubs full of 'em..

Digi-Comp I re-issue viability; recent auctions; friendsofdigicom p

by TMcNerney＠chipwrights.com

On the topic of the viability of a Digi-Comp I re-issue... In the past three months, two kits have been put up for auction on eBay. One fetched over $421.50. Most recently, an usassembled kit went for $148.50 after 22 bids by 10 distinct bidders. I personally have always wished for a "version 2," with tighter tolerances, smoother action, and perhaps even 4 "flip-flops" instead of the standard 3. Brass or aluminum instead of plastic would add an especially nice touch. After all, who's wife is going to let her husband display a plastic computer in the living room? On the other hand, a nice polished brass model in a glass case... FYI, there is a YahooGroups group named "friendsofdigicomp" with 178 members. Oh, right.... So why am I posting to the Classic Computing mailing list? Because a ClassicCmp member wrote me to say: "One person I know has taken molds from his example and is planng on re-issuing it as a kit." Whoever you are, I thought you'd be interested in the present supply-and-demand situation. A limited run of 100 at $50 a piece would probably sell-out without too much effort. My impression is that the vast majority of the friendsofdigicomp group members -don't- have one anymore. (Mine got thrown away when we moved in 1971...) Regards, --Tim McNerney Newton, MA Postscripts... Recently someone submitted a schematic of the Digi-Comp I electronic equivalent to friendsofdigicomp. I believe you need to join the group to view this: http://groups.yahoo.com/group/friendsofdigicomp/files/DC1-PLA.pdf BTW, I have DXF format CAD models of all the plastic parts, but only in 2D. There are scans of the plastic parts and manuals at the YahooGroups site.

Decwriter II available

by holmberg＠tiac.net

Hi, I have a Decwriter II that I want to pass along to whoever is willing to pick it up (my home is in North Andover, MA). This Decwriter II hasn't been used for years. This is a relatively heavy impact printer with a keyboard, on a metal stand, that takes wide continuous folded paper. It worked when I last used it, but has been sitting in the basement for a long time - no guarantees. There is a (headset) modem that goes with it. If there are no takers, I may have to junk it. However, if it is of use for anyone, I'd rather give it away. I'm not a member of this list, so please respond directly to me ASAP if there is any interest. Thanks, Carl holmberg at tiac dot net

Recent scans of my collection of 17"x22" PDP-8/I schematics are now available; many are different (newer) revision than others available on the web. http://www.parse.com/~pdp8/pdp8i/drawings.html There's a tarball so you can download the whole thing (11 Megs). Spozedly, these are 400 DPI scans, so they should be pretty reasonable quality. Cheers, -RK -- Robert Krten, PARSE Software Devices +1 613 599 8316.

scanning booklets for archive

by cb＠mythtech.net

I finally have a scanning system setup here for archiving documents. Does anyone have a good idea of how to deal with booklets? That is, items that are printed on 8.5x11 paper, then folded over and stapled. RIght now, I have been opening the booklet to the center, removing the paperclip, then cutting the booklet in half down the spine, and scanning the first half as double sided then the 2nd half as double sided in order to keep the pages in order. (obviously I'm concerned with multipage booklets) This is fine, for things that are headed to the trash after scanning, but for things I might want to hang on to, I don't really want to cut the booklet in half. Is there any recommendations on how best to keep the pages in order? What do others do? Or does everyone either leave them in printed bound order for later reprinting (which means in the wrong order for reading in a PDF, booklet printed order for a 12 page booklet would be 1/12, 2/11, 3/10 and so on) or do things the hard manual way by scanning to image, and cutting the image up into the right parts before going to PDF (right now I am doing things the lazy way and scanning directly into Acrobat so I'm never touching the raw image). Suggestions? -chris <http://www.mythtech.net>

Is the drive getting a head load signal or is the controller waiting for some status line from the drive? That would be the first place to look. There may be slight differences in the gating of these signals at the drive. I wouldn't think that the index pulse would cause troubles but you never know. On either drive, you should see index pulses. I'd have to dig out my manual to be able to help any more than that. Dwight

They don't seem particularly rare to >me. > >Jay West > Hi Rare and valuable are two different things. I have some rare computers that many would just grunt at if they saw them for sale at some swap meet. Things like Apple-1's have significant history as well as being rare. This enhances value ( way beyond any reasonable level ). Still, if you are one of those that is making a complete set of a particular type of machine, tracking down the unusual ones can be an issue. Just don't tell the seller he has something you really, REALLY, need. Some Beany Babies are quite rare. I wouldn't give you 10 cents for any of them. Some computers are quite rare. You'd have to pay me to take some of them away. Some rare machines are interesting because they are unusual. Others have no special attributes like some of the Cromemco S-100 work horses. There must be hundreds of variations of these, making each rare. They are still fine machines and worth saving but they have no special monetary value even though rare. Dwight

Plustek scanner manuals

by cb＠mythtech.net

Anyone want the manuals from a pair of Plustek scanners? These are from a pair of sheet feed scanners that I tossed a while back. I lacked the interface card for them, and couldn't find one, nor a taker for the scanners, so they went into the trash. I now have the two manuals from them. I also have a single floppy disk marked Scanner Utility that is in the bag with one of the manuals. Anyone want them before they get tossed as well (although now that I can scan manuals, they will get split in two, scanned, THEN tossed. And the disk will be imaged and archived... but before I ruin the manuals by cutting them down the spine, I want to make sure no one wants them intact) -chris <http://www.mythtech.net>

Canon Cat (was: Cannon Cat

by dwightk.elvey＠amd.com

Hi I did a search for "canon cat" with google in the news groups and found the trick to enable Forth on the Cat. There was a note from Derek Peschel that discribed it well enough that I was able to figure it out. It has two Forth modes. One uses the Forth engine to calculate things from the text of on the page. The next level of mode drops you into a Forth interpreter. It seems to take most Forth commands but I tried things like vlist and words but these were not part of the vocabulary. I'd like to see what its vocabulary is but it may not have a word defined to do this. It does have such words as C@ and @ as well as it compiles new words. This means I can do some exploring. I didn't try it but I think I can even use the text input as source from the first level. Dwight

scanning booklets for archive

by RCini＠congressfinancial.com

If I need to do this, I make a copy of the book using a copier at work. Many better copiers have a "book copy" mode where the spine is centered along the center line of the scanning bed and the copier automatically copies both pages.

Fujitsu (Fuji) Eagle manuals

by cheri-post＠web.de

Hi, Al, thanks alot to you as well ! I was still searching for the manuals of the M2333K drive, when I found them on spies.com . Two Super Eagles are waiting to be connected but I need some manuals of these either. My question: Are there essential differences between the Eagle - and the Super Eagle drives (M2351 vs. M2361) ? Could I use the docs for the M2351 to set the jumpers or should I wait until I get the correct manuals ? By the way: I got the service manual for the PRIAM V130/V150/V170/V185 drives 4 months ago and manuals for the CENTURY DATA Trident T200/T300 and T25/T50/T80 drives (I'm not sure, if the numbers are correct, I'll have to look it up the next weekend). Currently, I do not have the time to scan them as I'm writing exams but if anybody is interested, I could scan them in the comming months.

FA: Motorola Powerstack E PowerPC

by florit＠unixville.com

Hi everyone, I've got a rare, almost borderline classic-cmp system that is very interesting up for auction on ebay. I'm hoping a gentle soul will take it in and give it some play time. Pictures of the boombox stereo looking system: http://www.hudat.com/~florit/20030624-MotorolaPowerstack/ Getting to the mid-90s there was a lot of evolution in processor designs taking place; there was a question as to which company would lead the way into the future; some big players at the time were MIPS, Digital's Alpha, The IBM/Motorola/Apple consortium led PowerPC, and of course, Intel's x86 line. There was plenty of doubt at the time, because Microsoft, who was just then putting out Windows NT 4, supported all of these processors! We all know how the face off ended up. The system I have here is a Motorola Powerstack. It is super rare, I've only seen one other on ebay in 3 years. Its in great shape. I can run a myriad of operating systems: IBM's AIX, WinNT 4, Linux PPC and aparently a beta version of Solaris 2.5 for PowerPCs. As I understand, this system runs the PReP Openfirmware (replaces functions of PC's Bios is a more clean manner). Its called a PowerStack because you can add drive chassis by stacking them on top and adding power and scsi chain cables. In effect, you can make this a low profile computer by removing the section that contains the dat drive, currently. Motorola PowerPC 603e, 100mhz, 64MB ram. SCSI is onboard SCSI-2, with two one inch high removable media device bays, one one inch high non-removable bay for disk, and the scsi expansion enclosure. This particular model is loaded with a thin profile CDROM, floppy drive, 4 gig harddrive, and DAT tape drive (unknown size; 1 or 2g?). It has all kinds of interesting ports on the backside. Video is on a PCI card (Cirrus Logic?), and audio is onboard. There are three PCI slots on a riser board. This system is in distinguished company: It has an actual removable key to start and stop the system. I'm including the system manual, very useful to find out how to assemble/dissasemble the system to get to the insides. Included are the cables to connect the expansion bay scsi. I will also ship the original copy of Sun Solaris 2.5 Beta that was inside the Powerstack when I got it and the CDs with the debian linux ppc I was planning to install. I did not complete the install of debian linux, so it does not boot into the OS; there are some configuration issues to work out- I'd recommend a fresher and newer version of Debian anyhow, as this one is at least 3 years old. Here's the auction link, if you think you're interested: http://cgi.ebay.com/ws/eBayISAPI.dll?ViewItem&item=2742423893&category=4610 If you have any questions, please ask away.

help! shugart 801

by rigdonj＠cfl.rr.com

I have several systems that use Shugart 800-1 SS 8" disk drives. I've got several defective drives plus I've been wanting some spares. Last week I picked up 10 Shugart model 801 SS drives. Today I tried to use them on the same systems but I can't make them work. I've set all the jumpers and straps exactly the same as in the 800-1 drives but the 801s aren't working. The system knows the drive is there and detects the disk being in place and rotating and that the drive door closed but the drive never gets the head load signal. I'm using the same system, cables, power supply, etc with both drives so the only difference is the drives themselves. I've tried a couple of 801s and gotten exactly the same results with all of them so I don't think that it due to a drive failure. Anybody have any experience with these or have a good idea of what's wrong? Joe

eBay rescue

by classiccmp＠vintage-computer.com

I hope that there is a list member in the area of Sterling Virginia who is willing to "rescue" the IMS 8000 machine being sold in the auction referenced below. The seller states that "If there are no bids, the machine and disks will be taken to the Loudoun County, Virginia landfill." Here's a link to the auction: http://cgi.ebay.com/ws/eBayISAPI.dll? ViewItem&item=2743455193&category=4193 Considering the volume of stuff it would be a shame to see it lost like that. For those not interested in hitting eBay, I've copied the auction text below: IMS 8000 S-100 computer system This computer has a Z-80 processor, 64KB (128KB?) of RAM, and dual half- height 8" DSDD floppy drives. The 8" drives were replaced about 5 years ago; the machine has seen little use since then. Some assorted spare boards are included, as are about 500 floppies including master disks for CP/M, CP/M Plus, MP/M, PL/I, and lots of other software. A manual is included, and notebooks containing BIOS listings and notes on drivers. Industrial Micro Systems made systems of legendary reliability, and this machine, over 20 years old, is no exception. I used it a couple of months ago, and it worked perfectly. However, I'm short of space, so this piece of equipment needs a new home fast. It is large and heavy, with wooden sides and a steel chassis. I will not even attempt to ship it. The auction winner must pick it up in Sterling, Virginia. If there are no bids, the machine and disks will be taken to the Loudoun County, Virginia landfill. Please note: I have nothing to do with this auction, the seller or the merchandise. I am just trying to prevent the loss of an interesting artifact. If someone is local and can pick it up but isn't interested in keeping it, I _might_ be able to pay for shipping (at great risk to my health - my next computer might be my last if my wife follows through on her threats! :) Erik Klein www.vintage-computer.com/vcforum The Vintage Computer Forum

Tektronix storage display/terminal manual

by mhstein＠canada.com

Seems to me I read about someone acquiring a Tektronix storage display terminal; I had one of those years ago with ambitious plans to turn it into a storage scope which never came to anything, so out to the curb it went. However, a friend who worked at Tek at the time was kind enough to obtain a service manual and some spare boards for me (alas, the CRT was defunct) and, although the boards are probably gone, I believe I still have the manual somewhere, so if anybody needs one, send me the model number off-list and I'll try to find it and see if maybe that's the one. No promises though :) Also a binder of TekNotes from the 70's somewhere. (I think I promised it to Sellam many moons ago, but I'm sure he won't mind if I make a copy; besides, this would give me extra incentive to look for it). Almost two years ago I sent a stack of IBM unit record equipment manuals and wiring diagrams to someone (who shall remain nameless - you know who you are :) with the understanding that he would make them available on the Web; if they are, I haven't found them (and my apologies), but now I'm reluctant to give away fairly rare original manuals. m

What > percentage >> will upgrade to a current OSX running machine anytime soon? That's not quite the case. Macs have a considerably longer useful life than PCs, generally, and are indeed upgradeable. I just took my January 1999 model Blue G3/400 desktop, swapped the 8.5 GB Ultra2Wide SCSI disk subsystem for a fast 200 gig Maxtor and an ATA 133 card, slipped in an 800 mhz G3 CPU daughtercard and installed a Radeon 7000 instead of the OEM Rage 128 and a LiteOn 52x CDROM instead of the old Matushita 24x (I already have an external 1394 burner) and a Kensington 3-button Studio Mouse. Runs OS 10.26 like a charm. Sure a G5 would be faster but this setup handles a heavy duty OS10.26 without any strain, web pages render in a flash etc. Plus this one will still boot OS9 directly and I can use my old ADB keyboard of which I'm fond. I figure on getting a year or two more out of this machine by which time I may just buy a laptop and use the G3 for a file and web server. I would've LIKED a new machine, but didn't NEED one. Of the four households in this immediate family 3 are on OS X; only my 87 year old father in law doesn't want to upgrade his 1998 rev A iMac and install it. That's 75% penetration. Also the G3/400 daughtercard I removed is now installed in what was formerly a Beige G3/266 I keep at work as a scanning station. That leaves me with a spare ZIF G3/266 daughtercard. Anybody need one? Seth Lewin

OT-- need plans for a wireless switch

by nerdware＠ctgonline.org

I'm posting this here because, on the average, you guys are pretty smart. I'm trying to put a push-to-talk switch on the steering wheel of my car so I can key the 2-meter ham radio while keeping both hands on the wheel. I've got a little boom mic and have built an interface box, but how to mount the switch has me stumped. I picked up one of the velcro aircraft ptt buttons, which mounts nicely, but even with the relatively short turning radius of my Subaru it's still a good number of turns lock-to-lock and the coiled cord has a tendency to get snagged in the space between the wheel and steering column. My next thought is to use the aircraft button, but with a tiny transmitter/battery mounted on the wheel, with a receiver mounted under the steering column with a keying relay. Hit the button, the relay turns on, let up, the relay releases. I've been Googling for a while, but most tiny transmitters are either for "spy" audio apps, or are multi-button jobs for garage doors and things like that. All I need is a simple on/off fm transmitter that controls a simple relay on the receiver end, preferably powered by a couple of AA cells or similar, and the transmitter needs to be hackable so I can connect the wheel-mounted ptt switch. Any suggestions? I know this isn't directly related to Classiccmp, but it IS related to ham radio and electronics, and ham radio and electronics are related to hamfests, and hamfests attract computer collectors, so there. I just made the connection. Thanks. Paul Braun Cygnus Productions nerdware(a)ctgonline.org

Why is it that it's so easy to kill time, yet so hard to make it?

by ian_primus＠yahoo.com

Argh! I have had almost zero free time as of late. I have been busy with work, and on top of that, I have been sick. I have way too many things going on at the moment and nothing seems to be getting done. I'm trying to get caught up on email and various other things. To all the people that wanted to buy something from the basement sale, don't worry, I haven't forgotten about you, although your request may be buried in several feet of spam at the moment. I have been attempting to get my workshop to a point where I can actually work, and get things ready to ship out. In the process of cleaning, I have found many interesting things, like, for instance, my workbench. And the floor. Also, I have another heap of things that I really don't need, and I'll post that list once I get previous requests taken care of. Also, I have acquired a couple of new things for my collection, but I haven't had the time or space to play with them yet. Anyway, sorry for my apparent disappearance from the face of the 'net, I'm trying to get caught up... Ian Primus ian_primus(a)yahoo.com

Future uncollectable computers...

by Robert_Feldman＠jdedwards.com

In the business sector, the depreciation schedules written into the tax codes provide an incentive to replace hardware every 2 or 3 years, whether or not said hardware needs replacing. Back on the topic of this thread: wouldn't _ANY_ computer become collectable at some point, even something like a Packard-Bell, as, say, an example of an early-1990's commodity PC? Not that everyone would want one in their collection. Among the slide rules I own and have used are nice laminated bamboo K&E and Post examples, but I also have a plastic "clone" and a simple wooden no-name model. Perhaps the thrust of the original question should be "future inoperable or unrepairable computers..." Bob -----Original Message----- From: R. D.

Cannon Cat

by dwightk.elvey＠amd.com

Hi Al I finally got time to play with the Cannnon Cat. It powers up just fine and seems to run the disk OK as well. The battery is dead but that doesn't seem to be an issue. I fiddled with it some and found that if I hold the button in the back down during power up, it goes into the diagnostics. I know there is a way to cause it to go to the Forth prompt but I don't recall how it was done. If I can find a fellow named John Bumbgardener ( sp? ), he knows all of the tricks for these. Dwight

Old 7181 terminals

by Fred.Allen＠fujitsu.com.au

G'day Guys, just came across your query about 7181s. If you're still interested, here's some info:- These were an ICL-manufactured 2000 character text video terminal used for a variety of purposes in the early seventies. They were a replacement for the Cossor DIDS units. While later modules used new-fangled MOS memory, earlier models used a circular wire accoustic delay-line as the data storage element. In theory, this unit was in synch with the CRT scanning such that, as the electron beam reached a particular spot on the screen, the data for the character at that spot would just be appearing at the delay-line output. The speed of the data through the delay line was notoriously temperature sensative - a real problem in Australia if the air-conditioning broke down in summer! The spot scanning method was a little bizarre also - there were only 25 horizontal scans per frame but there was a small high frequency vertical scan component superimposed on the normal vertical scan, such during each of the 25 horizontal line scans, the beam 'painted' each character in that line character-by-character as it traversed the screen. ( Very different from the ~500+ pixel-line scan universally adopted by just about everyone else!. ) The keyboards were a parallel data design, and those fitted to the early 7181s were fitted with Hall-effect switch key modules ( I have a logic diagram of one of these somewhere! ) - a real "find" for the hobbyist! The 7181s on which I worked ( around 1972 ), talked across a synchronous V24 link to ICL System 4 mainframes. They used ICL's proprietary C03 protocol where multi-dropped terminals on one comms link could be individually polled for outstanding messages. Thus the operators were effectively entering data 'off-line' until they pressed the 'send' key, whereupon the next poll to that terminal would result in the date being transferred to the mainframe. Cheers Fred

Apple Clone

by ptremewe＠bigpond.net.au

I have one of these Plastic cased Apples. One question I do have is what sort of keyboard they use. The keyboard conector on the mother board is wited directly to a nine pin serial socket on the back of the machine. Does it use the standard Apple II keyboard in a special case?? I seem to remember seeing info on how to wire an IBM keyboard to an apple some where. Can this be done for this machine?? Or am I mistaken. In spite of my small collection of Apple II parts I have never really taken much notice of these machines until recently when I have decided to do a "clean out" so advice on how to get this Apple in a more useable state would be apreciated...... Peter T. > Looking at the motherboard it looks like a generic Apple ][+ clone.

Hello I have a Osborne 1b and when a boot up to CP/M everything on the A: disks works .But when I try to switch to the B: drive I get a R/W error. But If I format a disk on the B drive or A drive it formats it then B drive works with the floppy I formated and all other software disks work. But when I turn the osborne off and unplug it. after about 20 min unpluged I get the same error with drive B: and I have to the same thing. Is there a any fix for this? Thanks Casey.

Motorola Powerstack E PowerPC

by florit＠unixville.com

Hi everyone, I've got a rare, almost borderline classic-cmp system that I found very interesting up for auction on ebay. I'm hoping a gentle soul will take it in and give it some play time. Pictures of the boombox stereo looking system: http://www.hudat.com/~florit/20030624-MotorolaPowerstack/ Getting to the mid-90s there was a lot of evolution in processor designs taking place; there was a question as to which company would lead the way into the future; some big players at the time were MIPS, Digital's Alpha, The IBM/Motorola/Apple consortium led PowerPC, and of course, Intel's x86 line. There was plenty of doubt at the time, because Microsoft, who was just then putting out Windows NT 4, supported all of these processors! We all know how the face off ended up. The system I have here is a Motorola Powerstack. It is super rare, I've only seen one other on ebay in 3 years. Its in great shape. I can run a myriad of operating systems: IBM's AIX, WinNT 4, Linux PPC and aparently a beta version of Solaris 2.5 for PowerPCs. As I understand, this system runs the PReP Openfirmware (replaces functions of PC's Bios is a more clean manner). Its called a PowerStack because you can add drive chassis by stacking them on top and adding power and scsi chain cables. In effect, you can make this a low profile computer by removing the section that contains the dat drive, currently. Motorola PowerPC 603e, 100mhz, 64MB ram. SCSI is onboard SCSI-2, with two one inch high removable media device bays, one one inch high non-removable bay for disk, and the scsi expansion enclosure. This particular model is loaded with a thin profile CDROM, floppy drive, 4 gig harddrive, and DAT tape drive (unknown size; 1 or 2g?). It has all kinds of interesting ports on the backside. Video is on a PCI card (Cirrus Logic?), and audio is onboard. There are three PCI slots on a riser board. This system is in distinguished company: It has an actual removable key to start and stop the system. I'm including the system manual, very useful to find out how to assemble/dissasemble the system to get to the insides. Included are the cables to connect the expansion bay scsi. I will also ship the original copy of Sun Solaris 2.5 Beta that was inside the Powerstack when I got it and the CDs with the debian linux ppc I was planning to install. I did not complete the install of debian linux, so it does not boot into the OS; there are some configuration issues to work out- I'd recommend a fresher and newer version of Debian anyhow, as this one is at least 3 years old. Here's the auction link, if you think you're interested: http://cgi.ebay.com/ws/eBayISAPI.dll?ViewItem&item=2742423893&category=4610 If you have any questions, please ask away.
