Tips needed to repair Apple color composite monitor

by dastar＠ncal.verio.com

I just bought an Apple color composite monitor that needs some work. It comes on fine, and the screen goes to a bright white if I turn up the brightness. When I plug it into the computer the picture doesn't change a lick. I tried messing with all the settings to no avail. The picture stays a field of white. Any tips on how to proceed diagnosing this thing? I've got it opened up, the digital VOM is on and the soldering iron is hot.

The Amiga was a great machine for Graphics, Video, AND music during it's time (which is still ongoing). It was very easy to attach a midi interface and there were alot of really killer sequencers available. Plus, the Amiga bore the MOD music file format!

I agree with Anthony. (Why is smashing pottery always such a popular sideshow at the fair?) I have noticed a similar trend in other areas, such as sponsored events to raise money for charity. People always want to be sponsored to do something useless like walking 1000 miles or jumping out of an aeroplane (airplane). If it's a worthwhile cause they are supporting, I'll go ahead and sponsor them, but why can't we have sponsored events like "Pick up all the litter in the neighbourhood - sponsorship per bag collected"? The worst thing is, no-one would sponsor people to do something useful because "Aren't the council supposed to be doing it anyway? Why am I paying council tax? [Rant, Rant]" Sad, but that's human nature for you. Philip.

What it does have that other machines in the same class (early Mac's, early Amigas) don't have is built-in MIDI ports for connecting to musical keyboards and synthesizers. That's what I (would) use in my studio (if I had it all set up) for composition and sequencing. (Doncha just hate moving?) The 800XL is an updated version of the venerable 800. Has BASIC built-in and only one cartridge. Nice machine.

Shame, shame, shame

by maxeskin＠hotmail.com

Well, I don't necessarily see anything wrong with once in a while destroying a useless piece of junk, like a PC or a C64 (despite popular belief, third world countries will _not_ be better off with more computers). In general, moderated violence is vital in society, so that unmoderated violence is not as common. Singing and dancing is good too, but remember that Cain is the one who was a vegetarian. Of course, I have no idea why people showing off technology would want to do it by smashing stuff. Ah, that's life... >The whole exercise is such a Beavis and Butthead thing to do. > >It never ceases to amaze me that, when offered an opportunity to >celebrate in a positive manner, groups of people will choose to smash, >burn and destroy things instead.

I thought the only difference between the logic boards was the PROMs/PALs. Of course, not owning a Lisa, I can't be sure about this, alas... --- end of quote --- This is what I've heard, too. In fact, one of the newer Lisa gizmos sold by Dafax is a "ROM switcher" so you can use both the original Lisa H-roms and the modification 3A-roms without further tinkering. (I guess you'd just put up with oval circles and whatnot in Mac apps, since the ROM switcher doesn't do squat about changing the video.) All these repair manuals say "hang onto your old ROMS so you can run Lisa stuff in the future" which seems to indicate that it's feasible to revert the change. ??? -- MB

Have a Memorex Telex model B7000000 286 machine in a slim line case and a 3.5" floppy on a riser and a Quantum Prodrive 40S hard drive.

Does anyone know if this machine is a software setup or keystroke started CMOS and where to get the setup program or what the keystroke(s) are.

TOPS for PC, from sun

by peacock＠simconv.com

>Well, it says that it is a full networking OS that allows mac's and PC's to communicate, etc. seems somewhat along the lines of what francois has. also has a "secret proprietary etc etc" program disk called "RTERM", circa 1985. Daniel A. Seagraves wrote: > > If it is what I immediately thought it was, (Which it can't be, > DEC owned TOPS, not Sun...) *I WANT A COPY!* > > (TOPS-20 on a PC! The horror!) > ------- Seems there is some confusion here. TOPS-10 and TOPS-20 were DEC operating systems for the 36-bit DEC-10 and DEC-20 mainframes, circa late 60's (DEC-10) thru late 70's (DEC-20). TOPS dies when the VAX came out, thought there are vestiges left in VMS. The TOPS networking cards were essentially Appletalk cards for PCs. It was a low speed network using a Z80 SIO (or SCC?) serial USART and RS-422 drivers instead of RS-232. IIRC the speed was around 230Kbits/second (I have one in the back of a closet, haven't looked at it for a while). No relation to the TOPS operating system at all. Jack Peacock

Parallel-IDE interface for CP/M

by bobstek＠ix8.ix.netcom.com

Allison - IIRC, you were about to write some code to hook up one of these parallel-IDE HD kits to a CP/M machine with an EPP. Could this be made into a more generic project to allow file transfer over any CP/M parallel port? I for one would like to be able to transfer CP/M files from a variety of old systems to a portable IDE drive which could also be read on my PC in order to make archival copies of software for CD-ROMs. And I think there would be other interested parties as well. On another matter, thanks for the RAM 17 manual. And I'm sending you 2 unopened boxes of Dysan 10-hole hard sectored disks for your N*, plus another dozen of used, but perhaps not as used as some of yours, N* disks.

Strange MITS ad.

by rcini＠email.msn.com

Hello, all: While in the process of examining my old P-E and R-E magazines, I came across an ad for MITS from mid-1974. The ad was for a 4-channel digital handheld memory scope (model MS416) for $189. It seems to be a simple digital logic analyzer. Does any one have info on this?

In yet other backplanes, you find that it is Qbus in the AB slots and CD bus in the CD slots for part of the backplane (BA23 = three slots, BA123 = 4 slots) and then it switches to Qbus in both the AB and the CD sides. Bottom line -- make sure you know what backplane you are plugging boards into before you do so.

Shame, shame, shame

by peacock＠simconv.com

>It never ceases to amaze me that, when offered an opportunity to celebrate in a positive manner, groups of people will choose to smash, burn and destroy things instead. If it were some kind of demonstration against a particular company for some kind of social violations, it least smashing a computer made by that company would have some kind of symbolic purpose (albeit still a negative one). But to just smash something for the hell of it. How odd, seems like a natural thing to do. Many's the time I'd like to have taken the PC under my desk, loaded it into the trusty old trebuchet and slung it across the countryside. As for wanton destruction, don't knock it till you try it. Last month I had the opportunity to fire a 75mm cannon at some cars, wasted a really nice Subaru. Then I got to watch as the rest of the cars were strafed by a .50 Browning from a helicopter. It's a great feeling to watch a Lincoln being blown apart. We surely do live in the best of times. Jack Peacock

Odd Q-Bus questions 18/22bit

by allisonp＠world.std.com

< Well I'm not really a Qbus person. I never got into PDP-11s much and apa < from adding and removing boards from a uVAX-II didn't get to play with Q < much. The sort of thing I'm looking at is a little more sophisticated th < "a bus is something that connects cards together" but a little less bori < than a dry description of arcane features of signal timing and decay < (although I've read plenty of these in my time). let's see if I can do a little on this. Q-bus DECs compaction of Unibus. Qbus is a time multiplexed, asychronous, 16bit data and depending on age of the system 16, 18 or 22 bit address. It has termination and controlled loading to allow operation at high spped using open collector drivers. While a 16 bit bus it also supports various byte transfers. Q-bus is compact and fairly sparce in signals but supports memory, device, interrupt and DMA transfers using the bus data lines and a set of 10 control signals. There are other signals present for processor control such as RUN, PowerOK and Binit are examples. There are more pins than actual signals, some are redundant power for example. There are lines for bus mastering, DMA and interrupt grant/ack are examples. Most devices fall into several loose catagories, IO and memory. The lower 16bits are multiplexed on the bus before every transaction using the same lines data will be transferred on. Cards use BSYNC to capture address and start any bus cycle that pertains to them. Memory is fairly straight forward in that its timed off bsync and will use the other 9 signals to synchronize it's operation. Transactions will be read (word/byte) or write (word/byte). One of the characteristices of PDP-11s is they always read before write (a read modify write cycle is the normal thing). IO devices are identical to memory and by convention and use of BBS7 are located in the top page of the 32KW address space (1 11x xxx xxx xxx xxx). The remaining transacions of not are interrupts and DMA. Interrupts are posted via a request line that can be superceeded by another board physically (buswise) closer to the CPU and will be granted by the CPU to the higest(closest) requestor then and acceeding requesting modules. When an interrupt is granted the board will place a byte(7 bits lowest set to 0) VECTOR on the data bus that the processor will use as a pointer to a table in the first 512byts of ram (interrupts vector table PSW and interrupts service address is located in two words). DMA also has a grant acknowledge and positional priority. Once granted DMA may proceed with byte or word transfers of any length, though generally restricted to short bursts to avoid hogging the bus. The basic signals are: BDAL 0->15-L -L denotes active low signal BSYNC-L BBS7-L Predecoded bank 7 signal (IO bank) BAIKO-L Bus interrupt acknowledge BWTBT-L Bus Write Byte BRPLY-L Bus Cycle reply (must be supplied to continue the cycle or a bus time out error occurs) BDIN-L Bus Data IN toward CPU BDOUT-L Bus Data OUT -> to module Bus cycles have a distinct protocal (sequence) and timings. < Does this narrow it down a little? I'm sort of surprised that there isn' < nice description on the web somewhere.... Me too, though trivial it's not. I tried to avoid a description of each line as that is quite lengthly. Allison

Lisa 2 coversion from Mac XL

by bobstek＠ix5.ix.netcom.com

RE: the discussion on converting the Sun Remarketing Mac XL back to a Lisa 2 - I called Sun Remarketing and spoke with their most knowledgable Lisa person (thanks Marion!) who was less than encouraging about the project. According to him, it is not just replacing a few ROMs and PALs, and removing a transformer from the CRT yoke - it requires replacing the main logic board >from an original Lisa, and unless you have a wrecked Lisa, that item may be a little hard to find. On the other hand, this group always seems to have someone who, not knowing a task was impossible, did it anyway! I you're out there and have "done it" - please make yourself known!

>Two, not one, two Imsai's with Imsai disk units up for auction on ebay. Imsai disk unit as in the original 8" Calcomp floppy? Hmm, from '76? Be careful if it is, those drives had an extremely short lifespan (we experienced a 300% failure rate, every drive ordered failed, and replacements failed too).

They sent us a cardboard baffle to try to get it to work but the only real solution for us was to use a different brand of 8" drive. Did anyone ever have a good experience with Calcomp floppy drives? The controller was pretty sophisticated for it's day, used a channel type design, you sent it basic info and it read the data into memory.

Ataris

by kaikal＠MICROSOFT.com

The 800XL (circa 1983) is a streamlined version of the Atari 800 (circa 1979). Although the 800XL has 64K RAM standard, while the 800 could only support 48K, the 800 had an expansion bus that the 800XL lacks. The 800XL is a 1.79 MHz 6502 machine with 24K ROM including BASIC. It accepts most of the same peripherals as the 800, including software (mostly game) cartridges. It has 2 joystick ports that accept 2600-style joysticks. Floppy drives are available, which run Atari DOS. See http://www.geocities.com/~compcloset/atari800XL.htm. The Atari 520ST (circa 1985) is a 16 MHz Motorola 68000-based machine that was created to compete against the Commodore Amiga (Atari almost acquired Amiga Technologies before Commodore did, and was always jealous of that fact). It indeed runs a GEM-based GUI and the TOS operating system. The STf version has an internal floppy drive, and the STfm version has a floppy drive and RF modulator. See http://www.geocities.com/~compcloset/atari520stfm.htm.

TOPS for PC, from sun

by fauradon＠pclink.com

Right but the original post was about the PC-MAC network and not the DEC OS thus the path the thread is taking. There was also a TOPS for UNIX (Sun 386). Also TOPS could work through Ethernet (used mostly when UNIX was involved) wich would allow for more that just PC-MAC networks. According to the Book "Networking with TOPS" the original version was made by SUN. -----Original Message----- From: Jack Peacock <peacock(a)simconv.com> To: Discussion re-collecting of classic computers <classiccmp(a)u.washington.edu> Date: Monday, August 24, 1998 12:18 PM Subject: RE: TOPS for PC, from sun > >>Well, it says that it is a full networking OS that allows mac's and >PC's >to communicate, etc. seems somewhat along the lines of what francois >has. also has a "secret proprietary etc etc" program disk called >"RTERM", circa 1985. > >Daniel A.

Parallel-IDE interface for CP/M

by bobstek＠ix6.ix.netcom.com

Allison - IIRC, you were about to write some code to hook up one of these parallel-IDE HD kits to a CP/M machine with an EPP. Could this be made into a more generic project to allow file transfer over any CP/M parallel port? I for one would like to be able to transfer CP/M files from a variety of old systems to a portable IDE drive which could also be read on my PC in order to make archival copies of software for CD-ROMs. And I think there would be other interested parties as well. On another matter, thanks for the RAM 17 manual. And I'm sending you 2 unopened boxes of Dysan 10-hole hard sectored disks for your N*, plus another dozen of used, but perhaps not as used as some of yours, N* disks.

What I picked up from the ebay auction

by Anthony.Dellett＠Staples.com

Well, not only did I win the Ebay auction for all the 70's electronics parts (he didn't even want my winning bid), I went over this weekend to fill up my car (a 1990 Ford T-bird). I am going back to get the rest next weekend but I was able to fill my then empty trunk with 74lsxxx parts, all brand new in tubes (the guy believes there is at lease one tube of every part in the series in there). My back seat is full of 3M ribbon cable (various wire counts) and tons of din and card edge connectors. I think I grabbed a box full of 68K and Z80 processors also. What I'm nabbing next week; A NEC Spinwriter with a bunch of spindles, a box full of 10MB Priam hard drives, a box full of Shugart 8" floppy drives, more din and card edge connectors and (if I can get Allison's help) a 19" 6-foot rack :) Once I can go thru and sort all this stuff, I'll probably be offering them online for people that need them. I'll probably just charge for shipping, maybe a meager fee to offset the cost of storage. Tony

It's available for just about every computer platform there is (or was), and can deal with communications channels that X/Y/ZMODEM will just stare blankly at (for example, one-way-at-a-time async channels common on IBM mainframes). Even better, it can be just as fast or faster than ZMODEM. I use it just about every day to move data between RT-11, RSX-11, CP/M, VMS, Unix, MS-DOS, OS/8, etc... ----- Tim Shoppa Email: shoppa(a)trailing-edge.com Trailing Edge Technology Voice: 301-767-5917 7328 Bradley Blvd Fax: 301-767-5927 Bethesda, MD, USA 20817

Odd Q-Bus questions 18/22bit

by mbg＠world.std.com

>It's definitely hardware only. See my other reply to Daniel as to why I >don't know exactly what's on it.... Is there any service which duplicates fiche? (and produces something readable?) I remember making fiche for listings of various things back when I worked on some DECsystem-10s at the PK1 (parker St, Maynard, MA) facility. The fiche was produced by some device which read magtapes with machine-readable listings, produced on the -10... At one point, I did what was required to produce a set of fiche with the RT-11 listings on it... this was RT V2C.

OK, I've got the RX02 virtual disk images I want on my 486 (it's the one with the 1.2Mb floppy, booted into DOS, and started up 'putr'. I made a RX50 using putr, and go to copy the smltcp.dsk image to the RX50. Unfortunatly it complains that there isn't enough room. I take it that a RX50 is less than 500k? I think the image is 492k. Is there some way that I can split the disk images and then recombine them once I've got them copied over to the /73? I'm just not feeling energetic enough to want to move a RL02 drive around and juggle the controller between my MicroVAX and /73 to get the files transferred tonite. Zane | Zane H.

The only thing I can think of which might affect whether they are readable is whether the disk images you have are sector-by-sector image copies, or block-by-block image copies. If they were copied using one technique, but read using the other, then you'll actually be mixing unrelated sectors together to form a block. I would have to check the source (or ask Bob) which technique is supposed to be used to make image RX01/02 copies so that they work. >I'm wanting to use them on my SMS-1000.

I've experienced that with monitors before and the man who gave it to me (yes, you heard that right) said that it had been working but the monitor was not coming on anymore. He also added that he was able to get it up if he gently wiggled the circuit board at the back.

Colan --- end of quote --- Re: wiggling the circuit board. Perhaps the card's contacts are dirty -- try rubbing alcohol with a lint-free cloth, you might get lucky. The chirping sure sounds like a power supply thing to me...though for what it's worth, that was a real common problem (easily fixed) with the old compact Macs (128, 512, Plus) that used the analog board power supply. There was a distinctive ring of solder points, visible from the non-component side of the board, where the flyback transformer was attached (the blocky part with the little suction-cup connector that sends high voltage to the built-in CRT). Over time the solder would crack from repeated heat expansion and contraction. The symptom was either no video, or a more-or-less chirping sound. Often the solution was as simple as resoldering those points -- maybe there's some similarity with the Lisa's internals? Dafax Processing has replacement power supplies for $250 (gouge! Sun Remarketing sells a entire Lisa for that, I think. But it's Mac-modified, bummer.) Maybe there's a discount if you trade in your old one, I don't know. Dafax's number is 718-746-8220, and Sun Remarketing's is 1-800-821-3221 (maybe they have parts for less?) Good luck! -- MB

It's technically reversible if you have the old parts -- where to get them, I don't know. You'd need the voltage and screen-size specs to get it just right (and avoid blowing the power supply). Sun Remarketing still sells the mod kit, so perhaps they have the parts that were removed to do modifications? -- MB

TCP/IP for RT-11

by healyzh＠ix.netcom.com

OK, I've found the TCP/IP distributions on the Kent University web site. The thing is, they're on RX02 disk images of some sort. How on earth do I deal with these? They obviosly aren't compatible with Bob Supnik's Emulator, at least I couldn't access them. I'm wanting to use them on my SMS-1000. It is a PDP-11/73, 4Mb RAM, Ethernet, and a funky drive controller which in the case of the 5.25" floppy I believe is able to emulate either a RX50 (how it currently is set) or a RX02. I'm wondering if the RX02 mode requires the model with the 8" drive, which I just happen to have in a shed out back (obviously not as decked out, and with a dead hard drive, but still a /73).

Obviously, somewhere along the line, he was able to make the images from the original Lisa diskettes, but I don't know the details of this -- Disk Copy must be able to make images from weird disks (I know it can do ProDos ones.) Incidentally, there is a way to de-serialize LOS diskettes using FEdit -- I don't know where your set of disks came from, or whether they've been used. (The LOS install disks have to be un-write-protected because the first time you install the software, the installer reads the Lisa's unique hardware serial number and writes it to the disk for piracy prevention. If you ever try to install the software on another machine, it won't let you.) What's the matter with your Lisa? -- MB

Lisa II operating software

by bobstek＠ix7.ix.netcom.com

Let me make an offer (without knowing exactly what I'm getting into...) I haven't been following this thread too closely because I've never had a Lisa or even a Mac...until yesterday. I now am the proud (but ignorant) owner of a fully working 1 MB Lisa 2 (the Mac XL variety) with the 10 meg HD and 3.5" disk. If given explicit instructions on how to de-serialize, I'd be happy to make copies of whatever disks you would like. And since I've been short of time (and I'm lazy!) I'd appreciate a few choice URL's with solid info of all sorts on the Lisa - less on its history and more on hardware and software, operational hints, etc. Bob Stek bobstek(a)ix.netcom.com

Apple ///

by tomowad＠earthlink.net

I just purchased an Apple /// and noted some interesting differences between the new Apple /// and one I've had for a while. Upon turning on the new ///, it displays some garbage, then beeps and shows "Diagnostic RAM" on the screen, along with a square pattern of '.'s. Not until I press "Reset", does the comptuer dead the floppy drive My old Apple /// (which, BTW, I beleive to have some bad RAM) immediately starts reading the the floppy drive with no "Diagnostic RAM" or need to hit "Reset". Also noted: The new Apple /// has darker keycaps The older Apple /// has a shielded "Color Video" Port On the tags on the bottom of the units: The older has a place to check off either 64k 96k or 128k (128k is checked) The new has a place to check off either 128k or 256k (128k is checked) I understand there was an upgrade to the Apple /// dubbed the "Apple ///+". I was under the impression the '+' was actually written on the case. Is this the case, or is it possible my newer unit is a ///+? If its not, what causes the discrepancy in startup procedure? Just minutely different versions of the Apple ///, or does the older units bad RAM have something to do with it? Thanks!

[Fwd: Old plasma display]

I'm looking for some info on old Panasonic plasma displays.

Mac Portable problems (was Re: Mac Portable batt charger)

by rcini＠email.msn.com

I'm in the process on restroing one of these now, so I've had the same problems. I think that you can substitute a PB100/140 adapter for the stock MP adapter and have it work. The MP adapter is 7.5v at 1.5a. I think that the minimum for startup is north of 2a. I also just got a replacement CP3045 hard drive, and brand new batteries. Now I need to bring it up...

This Week's Haul

by ds_spenc＠alcor.concordia.ca

This'll seem insignificant to most Californians. :) I've hauled all this stuff home this week, even though I wasn't really looking for stuff (just lucky!): IBM PCjr (no power supply) Timex/Sinclair 1000 TS-1016 RAM cartridge TS-2040 Printer (no power supply) Dynalogic Hyperion VIC-1906 'Alien' game cartridge for VIC-20 'Tennis' cart for CoCo, with box and docs Carts for the Atari 2600 (yes, I know it's not a computer): Grand Prix, Gyruss, Jungle Hunt, Keystone Kapers, Mega Force, Skiing, Sky Jinks, Sorcerer, Star Wars: Return of the Jedi, Star Wars: The Empire Strikes Back, Vanguard, Zaxxon. All from the same Salvation Army store I cursed a few weeks back for tossing out all their computer junk. Well, they keep doing it, but I'll take back my curses because I understand why they'd do such heinous things. With the way stuff has been pouring in in the past couple of months, they must get innundated with this stuff! I have a feeling that if I visited every day or two, instead of every week or two, I'd be hauling away a lot more stuff. I'm still pissed off about the potential Wang monitor tossing, but these folks are clueless about what's worth keeping. Anyway, some notes about the stuff mentioned above... The Dynalogic Hyperion isn't in nearly as good shape as the last one I hauled out of the very same store. This one is _very_ yellowed, like it's been sitting directly in the sun for a few years. Which is probably why someone installed a wire mesh in front of the display. I figure it must've been an anti-glare measure, though it's still quite shiny so maybe it was just to ease the fears of a radiation-scared employee. Anyway, whoever installed the mesh cracked chunks of the case off here and there. They also neglected to replace several screws. The internal screws they left out would've been hard to put back, though, with that mesh in front of the display. Anyway, the front panel is kind of loose. At least the ports are all labeled on this Hyperion, so I'll have to revise the poor guesses (ahem) on my web page. :) Also, there aren't any knock-out panels on this one. I did notice that there are two EPROMs in the machine. I'm definitely going to have to get an EPROMmer of some sort. One of the EPROMs in this Hyperion is soldered directly to the PCB, though, which makes things difficult. (I haven't checked the other Hyperion.) This 'new' Hyperion has some 'display issues'. :) The display on the monitor isn't square, and it jumps inward and back out frequently. Something I found interesting about the Hyperion is that the cover comes off identically to that of an old Macintosh. Undo the screws under the handle, pop the rest of the case from the front face, and pull the case off. I was scared to try popping the case on the other Hyperion, but this busted up one just begged to be looked into. On to the TS-1000. Or at least, what I assume to be a TS-1000. The label is missing, as are three of its four rubber feet, and some gummy tape had been affixed to its top. Anyway, it's got "Timex Computer Corporation" printed on its underside, and it has 2K of RAM (verified with a PRINT PEEK 16389). The motherboard says "ZX81" on it. The Sinclair ZX81 was the first computer I really wanted to buy. (Note that this is VERY different from wanting to OWN - I could actually almost afford a ZX81, I definitely could NOT afford the Northstar Advantage in one of the local shopping centres ;) ). So finally getting my hands on one is pretty special. And I was even introduced to its innards right away, because the damn thing had dead keys on the keyboard. :) It just turned out to be cracked plastic contact strip thingies. I just trimmed the contacts with scissors and shoved them back into the sockets. Hopefully I won't have to do that again or I'll run out of slack. :) It's kind of neat that I can actually SEE how the keyboard is wired, without opening the keyboard. :) The big metal ground thingy on the bottom of the board also broke off at one end. Bad solder job, I guess. :) I'm just using my Atari 2600 power supply at the moment, because the ZX81 supply wasn't there. Man is this thing slow! :) Up until now the (unexpanded) TI-99/4A was my slowest, crappiest system, but the Sinclair thing beats it for that title so easily it's not funny! But it's got nostalgic value the TI will never have for me. And besides, TIs are like earwigs around here. The Salvation Army has put at least 50 in the landfill that I know about. But this is the first Sinclair machine to turn up. The RAM cartridge has a broken, wobbly connector, and bent pins, and I can't get it to work reliably. The printer doesn't have a power supply (anyone know the specs?) or the roll of toiled paper, so I don't know if it works yet. I also don't know if the PCjr works. The external transformer was missing. I got the better keyboard with the thing, too, instead of the original button keyboard. I actually have the Tech Ref for the PCjr sitting around in a box somewhere, so it'll be cool to go poking around in it as soon as I know how. I haven't tested the VIC or CoCo carts yet, but the 2600 carts all work with the exception of Jungle Hunt, which I think just has dirty contacts. It's an Atari cartridge, though, so the contacts are 'protected' and I haven't bothered to find something to stick in those slots yet. Other recent acquisitions include an IBM-PC (5150) with 64-256K motherboard (damn!), an Atari 400 with several books, magazines, and cartridges, and some cool toys for my Amigas. The collecting has been pretty good this summer. Doug Spence ds_spenc(a)alcor.concordia.ca http://alcor.concordia.ca/~ds_spenc/

looking for...SYQUEST 270

by allisonp＠world.std.com

Can anyone help me I was just given a parallel port syquest 270 external cartridge disk. I don't have the install disk... well I do but it's hopelessly munged. I need that so I can do transfer media to PC from... More importantly I want to try and hang it on one of the CP/M systems that happens (by my design) to have a EPP compatable port. So, I need the gory details of how to talk to such a critter so I can write a CP/M bios. And you thought it's all non classic! Graft new technology to old and keep it crankin. Allison

Macs, IBM systems, roms, etc etc...

by poesie＠geocities.com

Ok, after a few more days of scoping things out, here's the deal: I started working for GE Capital, at Blue Cross/Blue Shield of Minnesota. They are disposing of alot of the mac systems, and I figured that I would be able to pull the ROM's out of the old ones that I knew were never going to be used again, ever. (Just so you know, I would probably lose my job due to that but it's a shame to let such things go to waste. If someone reading this is from my new employers, I haven't done anything!!!!!) Anyway, one of my bosses, the asset manager, is actively trying to dispose of pallets of stuff. So if someone out there can actually buy quite a bit, that might be nice... apparently last year he made 300 bucks selling all systems to scrap dealers that melted it all for the metal content. bummer.) We have lots of old IBM mainframe systems, Quads, CRTs, etc etc. also, a good lot of those macs were all used by the Graphic Design dept; so they are chock full of cool stuff (tons of ram, souped up video cards, yadda yadda.) lots of hard drives, all have token ring cards. (I reiterate: LOTS of token ring cards. I'm swimming in them.) I currently have a large pallet of mac 14/15 inch monitors; a pallet of IIsi, IIci, IIcx's; Quadra 700s, Quadra 950 servers(awesome machines), PowerPC 7100/66, 7100/80's. also other random ones. also, *several* pallets of Duo Dock 230's and 280's. tons of NEC versa V/50's and 4000c's. quite a few 21 inch mac color monitors (definitely not for sale, unless you made an attractive offer to my boss!) alot of this stuff is earmarked for employee sales, but alot of it is also headed for disposal. If anyone is truly interested, I will print out and give serious inquiries to my boss. emailing the head of a large national corporation won't do much, but I can give your requests to the right person. in Minneapolis, Minnesota. -Eric (PS. - I only offered to grab roms or small chip components because they wouldn't be used where the machines were headed, and they wouldn't be missed. I cannot personally recover systems or anything of that nature. I am sure however that my boss would be very reasonable if you made an offer!) PPS- we also have several sony trinitron touch screens. anyone know of a use for these?

Sounds like a complete IBM 4381 installation (the 4381 was known as the Chest Freezer when I was there in '86) If I (a) had space and (b) was on the same side of the Atlantic, I'd grab it.

There was nothing else remotely like it at the time, and it >was even reasonably priced (around $5000, I think). In addition to the pictures I have on my Web site, David Hicks' Museum of HP Calculators has a bunch more info on the 9830 and the available peripherals (including things like printer, plotter, paper tape reader, digitizer, etc.). I was surprised when I got my 9830A and it had aftermarket ROM and memory cards in it. The ROM is a "Fast Basic" card and it and the memory were made by Infotek. The 9830 has a bus architecture for it's main ROM and memory cards, and it has an I/O bus on the rear. I don't know if HP ever published the specs for these buses, perhaps Infotek reverse- engineered the timing/functionality to make their cards. Also curious about the Infotek cards was that the markings on all the ICs on their cards had been intentionally rubbed off. I wonder if that was to make it harder for others to clone their design. At any rate, it predated the Apple II by about 5 years, it has built-in BASIC and storage, and you could add stuff to it. What more could you ask ;-) The darned things are built like a tank, too. Extremely heavy and rugged. There is also a 9830B version, but from what I can tell by comparing the guts they are the same except for the memory cards (the 9830B supports more RAM). It looks like the Infotek memory card in my 9830A was used to upgrade it to the same amount as would be in a maxed-out 9830B (16K, I'm not sure if this is words or bytes). > >-- Doug At Wed, 19 Aug 1998 19:12:22 dave dameron wrote: >At 05:41 PM 8/19/98 -0500, Doug wrote: >I found a book I would recommend if anyone finds a copy, although I am still >getting used to it.

Text (and some/most of the photos) from the HP Journal articles about the 9100A (and a lot of other HP calcs) can be found on the Museum of HP Calculators in the "HP Journal Articles" section. These make for very interesting reading about the machine's architecture and how it works. I have a copy of the original patent on the 9100 (unfortunately the quality isn't good enough to scan and I haven't found an on-line source yet), this gives some real insight into how the machine operates. The Olivetti Programma 101 was apparently targeted more for the business market than the scientific market, the pictures of it that I've seen show that it's basically a programmable, four-function calculator with several memory registers. Like the 9100, it used a magnetic card to store programs. >-Dave > At 12:38 AM 8/20/98 -0500, Doug Yowza wrote: > >Somebody with a better sense of calc history should chime in here, but I >think Monroe, Olivetti, HP, and Wang all had programmables in the 60s. As far as I know, the Mathatron, HP9100, and Wang calculators were the only scientific-oriented programmable machines available during the 1960s. I don't know if the Wang LOCI series was programmable or not. The 300-series (300, 310, 320, 360) Wang machines used a separate keyboard/nixie display unit and an electronics box with the actual calculator (on some of the models four keyboard/ display units could be attached to "time-share" the calculator electronics). The electronics box itself wasn't programmable, but one of the keyboard/display models (I think it was the 370) could be programmed to execute a series of key sequences, which were then sent down to the electronics box to do the math. In the early 70s (late 1970 or early 1971), CompuCorp developed a pair of programmable calculators (one printing, one Nixie) that were marketed by Monroe (the Model 1655 is the Nixie one) and Dietzgen. Rick Bensene's Web page has a lot more info about the Wang 300 series calculators. In the 60s, there were business-type programmable machines from Monroe (EPIC 3000), Olivetti (Programma 101), Smith Corona Marchant (Cogito 516 PR), and Canon (Canola 164P). There is also the Burroughs C3660 business programmable, but I don't know if it's a 60s machine or not, and Sony made a programmable Sobax but I'm not sure when. All of these machines were very large and were probably either transistorized or used early Small-Scale integrated circuits. > >I have an HP9100A manual and the first HP _Keyboard_ that describes it.

Punch cards (again)

by peacock＠simconv.com

>She said that they were invented by Hollerith at the end of the last century for use with the census. Was I drunk or did we just go through a whole discussion about the cards being invented for the Jacquard loom? Different types of punched cards. Hollerith invented the modern computer punch card. The Jacquard loom used punched cards in a linked belt type arrangement, similar to a player piano, to control the shuttle of his loom. Jacquard had more in common with pianos than computers.

Someone Looking for Help

by rax＠warbaby.com

Is this iron old enough that someone here could help Vicki? To: silent-tristero(a)world.std.com From: Vicki Rosenzweig <vr(a)zebra.acm.org> Date: Thu, 20 Aug 1998 17:01:18 -0400 (EDT) Subject: help--trailing edge equipment Sender: silent-tristero-approval(a)world.std.com Precedence: list Reply-To: Vicki Rosenzweig <vr(a)zebra.acm.org> Status: U I'm not sure this is relevant to tristero, but I can't think of who else to ask. I have a network of three Sun Sparc IPXs, plus an Annex II terminal server and a bunch of dumb terminals hanging off the Annex. Xylogics, the company that made the Annex, is no longer supporting that model, at all--the last time I tried calling them about something, the only suggestion they were willing to make was "we could sell you something more modern." It may come to that, but I hope not. Here's the situation: for Reasons Too Complicated To Explain (in other words, I'd start frothing at the mouth), the cables that connect the Annex to its dumb terminals and to the Ethernet are in the open, under a desk. Thus, they get kicked semi-regularly. Someone kicked the cable connecting the Annex to the Ethernet transceiver loose this afternoon. The first I knew of it was when someone came to find me, and asked why all the terminals were dead. When I tried to plug it back in, I found I couldn't--a couple of the pins on the transceiver had been bent out of shape. I replaced the transceiver (with one of a different model, but which I know is good--it worked elsewhere in this network). Nothing. I rebooted the Annex: it gets as far as a set of lights that translate to "trying to reach the Ethernet to download software." I got desperate, pulled the only other cable of the same kind off the network (which involved undoing about eight NFS cross-mounts), and plugged it in instead. Nothing. So, basically: I tried replacing the transceiver, I tried replacing the cable, and the Annex box insists that it's fine, it just needs to download software. Does anyone have any idea of what might be going on here, or of how I can fix it? (I do know where to buy a live chicken, but I suspect management would look askance if I brought it into the office.)

This was most likely due to condensation inside the drives. ---- Actually, it's Dartmouth College (NH) but I'm telnetting in from Miami, FL because I'm home for the summer. As far as I know, these drives haven't seen cold weather, but it's certainly possible. ---- If I read your post correctly the drives aren't spinning up at all, but they emit noises which make it sound as if they are trying to - in this case they are most likely stuck. I have convinced old hard drives to become 'unstuck' by whacking them on the side. I know it sounds cruel but if the drive isn't working there is nothing to loose. ---- Yeah, I tried that -- it's worked many times before, but not now. (The technician I worked for six years ago used to fix Mac SE's with sticky hard drives by picking up the whole computer and giving it a quick half-spin with a sudden stop -- the torque loosens the lubricant.) ---- Also, when the death chimes sound, is there a picture of a sad mac on the screen with an error number? The error number (if I remember correctly) may be a key indication as to what is happening. If your mac is repeatedly sounding the death chimes it is in some kind of endless loop and you are most likely not getting to the error #. ---- When I let it go long enough, I get a sad mac with error codes which I haven't looked up in the TIL yet. They all translate to some hardware (occasionally software) problem diagnosis. ---- I have also opened the drives and lubricated the 'spindle' or whatever it's called - however doing so allowed dust particles inside the drive. The end result though was a reliable, non sticking drive that works to this day. Perhaps I was lucky... --- end of quote --- Huh, I always thought that opening up a drive would wreck it -- maybe I'll try that with one of them. Thanks. But wait, there's more! New problem. I have an external hard drive attached to the least messed-up Portable, which boots nicely, but anytime I insert a floppy disk, the machine restarts over and over. What triggers it is pushing the tiny white button just inside the floppy (it gets pressed by the disk usually, but I was trying to see what exactly was setting the restart loop in motion, and when I pushed down on that button alone that did it). It WAS working fine with floppies before. Guess the logic board is having problems handling both at once. Aaargh! Three bad drives and now *two* fouled-up motherboards. -- MB

Update on Mac Run

by jrkeys＠concentric.net

So far I have heard from 12 people wanting a total 35 cpu's and 4 monitors. I would have liked to make them a offer this Friday but this is not enough units to purchase it all. This what I will do now, I will connact a scrape dealer I know and offer to buy it all with him only if he allows me to pull the units you guys want first and he gets what's left. This way we all can get our units at a low price with a bulk purchase by the pound. I have not heard back from Eric if his boss is willing sell and the date of the employee sale. I will until Monday to see how many more people want in otherwise the 12 of you will get your items if the sale is a go.

here's a Lisa/Apple /// resource

I'm posting some info I already sent to someone privately. I wanted to get permission from Mr. Craig first, in case he was trying to keep the volume of requests down or something. My apologies for wasted bandwidth if y'all already knew about him -- just trying to help. - MB --- awhile ago, Sam Ismail wrote: Ok, so I'd like to make use of the recent discussion we had concerning hard drive repair and attack the "widget" drive in my Lisa 2/10 to see if I can bring it back to life. Does anybody know where I can find technical info on this drive? A web resource that I don't know about perhaps? --- end of quote --- David T. Craig, email 71533.606(a)compuserve.com, has just about EVERYTHING ever written about/for the Lisa. (Even the Product Introduction Plan!) There's a list of his stuff at http://www.atomicnet.com.au/simon/lisa/LisaLegacy/References.html. While you're there, check out his Lisa Legacy paper. He sent me copies of Lisa repair stuff from Apple, Sun Remarketing, and Larry Pina's "Mac Repair Secrets" book, as well as some historical info and a set of Lisa Office System 3.0 diskettes and LisaTest diagnostic diskettes w/ instructions. He copied the written stuff for ten cents a page and the diskettes for a buck apiece, plus shipping. He also has some stuff for the Apple ///, but I don't know what. Email him for info. If anyone wants Lisa help right away, I can look up error codes and other stuff in the manuals he sent me, and email an answer usually within a day. My 2/10 displayed error 84, which means the boot blocks had been erased, but luckily LisaTest reported no damaged blocks, so all it needs is a low-level format. Sun Remarketing will reformat Widget drives and send them back (which is, according to the manuals, your only hope if LOS installer refuses to do it, as was the case with mine). It costs $75 to have them do it, which includes return shipping. They will install the OS of your choice (LOS or MacWorks, maybe Pascal Workshop but I don't know for sure). Sun Remarketing's phone number is 1-800-821-3221. If you get someone who's never heard of the Lisa or some such nonsense (which happened to me the first time) ask for Brian, ext. 340. He seems to know what's up. -- MB

Clock speeds may not be comparable. 6800 and friends (including 6502) often do more per cycle than 2901s. That said, the 4052 is a 16 bit system, despite its 8-bit instruction set. The data path is 16 bit throughout, it fetches two byte instructions in a single memory cycle, etc. And Tek do claim some quite impressive performance boosts upgrading from 4051 to 4052 (average gain they claimed was ten times, I think) > Yikes!!

Bear in mind Tony Duell's comments - 16 bit systems based around 4 2901s used to be common, but may now be worth grabbing anyway. I must do some more research into the relationship between 4052 and 6800 instruction sets. P.

Actually, according to Apple Service Source docs (found 'em after I posted the question) the charger puts out about a volt less. The power adapter itself is fine, but the external charger seems to be fried. I have a more pressing problem now. Basically, the computer has a grand mal seizure whenever the internal hard drive is connected. I've got three semi-functional Portables, and am hoping to wind up with at least one that works. But they all seem to have bad hard disks (Apple 40SC internal) -- if the drive is connected at power-up, it makes a tick-tick-tick noise, the screen flashes, and it repeatedly plays interrupted Death Chimes until I turn it off. The drive never actually spins up. I'm not familiar with that hard drive model. Since there's no separate power cable, I assume it's some sort of funky low-power-combined-with-SCSI thing. So, anyone got any ideas about what to do with them (besides drop-kick 'em into a swimming pool)? Is there some goofy reset I can do, or a bad fuse somewhere to replace? If there's no repair possible, then is there any other kind of hard drive that will work in a Portable? Or does someone have a spare they'd sell/trade? -- MB

Is the mail Lead-Acid battery any good? If the battery is discharged or shot, the computer won't power up at all. This may be your problem. I believe it is a 6V battery. If I'm correct, then one out of a power wheels thing should work to find out if it's a battery, or a bad computer. -- -Jason (roblwill(a)usaor.net) ICQ#-1730318 ---------- > From: Marion Bates <Marion.Bates(a)Dartmouth.EDU> > To: Discussion re-collecting of classic computers <classiccmp(a)u.washington.edu> > Subject: Re: Mac Portable problems (was Re: Mac Portable batt charger) > Date: Thursday, August 20, 1998 3:19 PM > > I checked the backup battery and it read 8.7 volts or something, which I > figured was adequate...maybe not? > > > -- MB

Not that I know of. TSC went under some years ago; we all assumed that it took the source to its grave. Rumour has it that some former employees of TSC *may* possess some sources, but they have not stepped foreward. FWIW: A co-worker of mine was approached some years ago with an offer to sell the FLEX sources. My co-worker wasn't interested, and the guy went away. Don't know who he was. For all we know, it ended up in the dumpster. :-/ Jeff At 02:33 PM 8/20/98 -0500, you wrote: > >< For years, it was *THE* disk operating system if you had a 6800/6802 bas >< system.

Hmmm... Seems that if a Mac Portable battery is dead, you cant power the machine even with the AC adaptor. I'm certain this has something to do with my problem. It also seems that if the Mac Portable battery ever gets discharged below 5.4v it becomes a doorstop. Tony

MCA ethernet cards

by rhblake＠bbtel.com

Still in need of a few microchannel (for PS/2) ethernet adapters with the BNC 10base2 setup. Doesn't matter if they have AUI or RJ45 with it as well, as long as it has the BNC/10base2 setup. I don't need 3270 cards so check any cards you think you have with the BNC connector to see what they are. Looking for donations, trades or reasonable priced cards for a parochial school network project that's overdue. I've gotten a few good reponses and have a couple on the way but I'm going to be about 4 or so short yet. I've also gotten one or two ridiculously high quotes for used cards. This is a project on a shoestring budget so no $30 or $40 cards please. Russ Blakeman Harned, KY USA

Kaypro 4 for trade

The machine itself is complete and working but I do not have any diskettes for it. On power up it displays a "please insert system diskette in drive" type of message.

Cleaning RL02 Packs

by healyzh＠ix.netcom.com

Question of the day, how do you go about cleaning an RL02 pack. I'm not talking about the "Customer" cleaning that the user manual talks about. I'm talking about the "Dec Certified Tech" six month cleaning or however it was they put it (read it last night). The six month cleaning sounds like it includes cleaning inside the pack, which is what I"m interested in. I know someone, Tony I think, mentioned taking apart and cleaning RK05 packs. Well that's what I'm wanting to do with this RL02. It's called the pack is visably dirty inside, with a thin film of grim. Any suggestions, recommendations, crys of "are you out of your freaking mind"? Zane | Zane H.

Save for your limited to the 1meg of ram (no CD) and the power is limited. the vt103 was designed as a small system and if you smoke the PS you may have a time finding another. Allison

Mathatron & other stuff

by aknight＠mindspring.com

Hello out there in classic computer land, I'm new to the list and wanted to introduce myself and my Web pages to the rest of ya'll. My name is Alex Knight and my Web page, the Calculator History and Technology Archive, is located at: http://aknight.home.mindspring.com/calc.htm My interest is primarily in early-model electronic calculators, but there are some crossover machines that seem to fit the bill as classic computers, and in my searching for old calculators I sometimes turn up some interesting old computer stuff. One of the more interesting machines that I have written an article about for my Web site is called a Mathatron, which was advertised as a desktop calculator/computer and sold as early as 1964. The Mathatron is a very large and heavy (24" x 24", 80 lbs) machine, but it will fit on top of a sturdy desk. I believe it to be the first programmable calculator, and some other people I've talked to consider it to be the first desktop computer (because of it's programmability, available peripherals, etc.). So ya'll take a look and let me know if you have any additional info. on this unit that I may be able to add to my article. Another "crossover" machine that I have a little info (mainly pictures) of is the HP 9830, called a calculator but in fact a computer with BASIC. Also on my Web site is a list of things that I'm looking for and things I have for trading, as I find classic computer items that I put on the trading block I'll send a message to the list to let ya'll know. Have fun, Alex Knight Hillsborough, NC

Of course, there were lots of new things added although sitting here I can't think of what - it's been a while since 5.5 was released!

Charging batteries

by tomowad＠earthlink.net

I have an Outbound Notebook which takes a camcorder-style 12v 2 Ah battery. The Outbound's power adapter, which is used to both run the unit and charge the battery is 22v, 0.82A. Unfortunately, I don't have the adapter or anything similiar. What I would like to know is how forgiving the Outbound and its battery would be if I used an innapropriate adapter. I have an adapter that puts out 14v and 1.2 amps. Am I correct in assuming the 14v would suffice for charging the batter (not running the unit)? What about the 1.2Ah, though? Will the extra amperage do any harm? Thanks. Tom Owad P.S. Anybody have a 22v, 0.82A adapter for sale? -- Sysop of Caesarville Online Client software at: <http://home.earthlink.net/~tomowad/>

Speaking of New Aquisition....

by cfandt＠servtech.com

I got a VMS ver. 5.4 "Grey Wall" myself with the 'Great Haul' a while back. I took an inventory of all the manuals based on the first several pages of the Introduction to the Master Index (found in General User vol. 1) I discovered at least four binders are missing. Not too bad considering there seems to be a total of at least 29 grey binders in the whole of the three manual subkits. They probably were left on somebody's desk at the southern college from where the previous owner obtained my VAX 11/750 back in '90 or '91. Would anybody have just odd parts and pieces of the VMS 5.4 manual collection? If so, would any of you be willing to part with several to help complete mine? Here's the manuals/binders I'm missing: General User Subkit Volume 4, "VMS DCL Dictionary" (may consist of vol. 4A and 4B in one _or_ two binders as hinted by a footnote.) System Management Subkit Volume 3, consisting of : "VMS Access Control List Editor Manual", "VMS Audit Analysis Utility Manual", "VMS Authorize Utility Manual", "Guide to VMS System Security" all in one binder. Programming Subkit Volume 7A, consisting of: "VMS I/O User's Reference Manual: Part I" and "VMS I/O User's Reference Manual: Part II" both in one binder. Programming Subkit Volume 7B, consisting of: "VMS Delta/XDelta Utility Manual" and "VMS System Dump Analyzer Utility Manual" both in one binder. Later, I may ask for help in completing my RSX-11M ver. 4.1 'Orange Wall" when I get around to doing a precise inventory. Seems to be several of those binders missing. (At least my RT-11 ver. 4.1 manual set seems quite complete :-) ) Thanks loads for the help! Regards, Chris -- -- ======================================================= Christian R.

Will the extra amperage do any harm? I don't know the outbound, but I can offer the following thoughts: To charge a 12V battery with a 22V power supply suggests some internal regulation, in which case 14V probably wouldn't work. On the other hand, it probably would do no harm. You don't say whether the 22V is dc or ac - if it's ac, dc might work, but if it's supposed to be dc, ac could damage your machine. Most power adapters are constant voltage, and quote a maximum current. So the requirement is for 22V, capable of at least 0.82A. A power supply that can put out 1.2A (not Ah) would be ideal. > P.S. Anybody have a 22v, 0.82A adapter for sale? I could build you one, but shipping it to the US might be expensive :-) Philip.
