slightly OT: looking for an HP deskjet accessory

by ghldbrd＠ccp.com

I'm sorry, this is only 5 years old, but I'm looking for the large paper feeder that holds a ream of paper for a Hewlett Packard 1600CM printer. I've never seen one, but I think it is a separate unit the printer sits on. Maybe in your travels you might see one in a dusty corner somewhere. Thanks. Gary Hildebrand St. Joseph, MO

honeywell manuals

by Fritz_Chwolka＠t-online.de

Hi.. I got some documents about honewell GCOS6 and other. The computers were used in the 8ths in an powerstation for collecting informations for the management. I don't know what models were used. Untill I own no hardware from honewll I'll scan the documents and put them onto. After scanning they go into the dumpster as I have no place left. http://oldcomputers.dyndns.org/public/pub/rechner/honeywell/manuals/ Greetings from Fritz Chwolka <collecting old computers just for fun> > www.alterechner.de <

Soroc was: new finds

by yakowenk＠cs.unc.edu

Hey Joe, How sure are you about IQ-120's having 1802's? ISTR doing a class project on that, studied the schematics (wish I had those now!), and concluded that the design was very much like a microcoded CPU - some PAL or PGA controlling register transfers, with a state register acting as a kind of micro-program counter... Now I wonder if that was some other terminal. It was 20 years ago, and my memory aint what it used to be. I may be interested in that IQ-130; I'll e-mail you off-list. My IQ-135 is actually in pieces (courtesy of UPS ten years ago). But there's a happy ending: I've found somebody with an ailing IQ-135 that needs parts. I'm packing it up for shipping now. Bill.

"The Mark-8 was an Intel 8008" was Re: I thought the Univac was expensive

by Innfogra＠aol.com

It is an interesting batch of sales. If you look at their other listings there is an Intel iPSC, a MASPAR and what I think is an IBM 5100 listed with the a strange title "The Mark-8 was an Intel 8008" listed in "antiques." http://cgi.ebay.com.au/ws/eBayISAPI.dll?ViewItem&category=12&item=2542757186 I, too, am inclined that the seller has a problem with decimals. I think they are very unfamiliar with eBay, having just registered. The ads are in the wrong categories. The descriptions are not what would sell a piece of equipment. Also seller in Japan, listed on the Australian eBay site with shipping in misquoted US Dollars. I suspect a Newbie or possibly fraudulent (low probability but worth being very careful) Does anyone recognize the pictures as being from somewhere else on the WEB. Many Japanese are collectors so it could be an original collection. The high valuations lead me to think it might be a collector. If you search their completed sales they are all collectable baseball cards. http://cgi6.ebay.com.au/ws/eBayISAPI.dll?MfcISAPICommand=ViewListedItems& userid=extremejordanfanno1&include=0&since=30&sort=2&rows=100 They brought good money too. The Ford Typewriter is also getting good bids at a price that indicate the decimal places are not misplaced. I suspect a Japanese collector that is a newbie to eBay, and needs to raise money.

Acorn (Was Re: Reading PDP-8 paper tapes)

by gtoal＠gtoal.com

> I have a couple of Acorn Systems (one 6502, the other 6809-based). I am > always looking for any of the more unusual I/O cards for them.... OK, refresh my memory here... what Acorn 6809 system would that be? I was only aware of two - one by Brian Jones which was a large hand- made breadboarded circuit he did as an experiment, and which ran FLEX, and one that I made which was a BBC second processor - *both* of which I have here at home. I don't remember Acorn making any production 6809 systems??? I have the original circuit diagram on tracing paper that Brian drew. My own was so simple (5 packages as I recall) that I didn't bother drawing a diagram :-) [I just worked from an ascii wiring list] I did two versions - the first was CPU TUBE ls139? (some single ttl chip for address decoding the tube) 2*32K 'greenwich instruments' battery-backed static rams I pre-loaded the static ram on a beeb with the boot code, so didn't need an eprom at all! the second was CPU TUBE Eprom 64K dynamic ram SIL (first SIL I ever saw!) Custom dynamic memory controller IC I was working on VLSI design tools at the time, and I designed the memory controller chip as my test piece. It was a PLA and a counter for ram refresh, not much else. [I found a 'work in progress' kernel source for my 6809 2nd proc earlier this year - written in Skimp, which was a compiler I had written myself as a University project; the compiler itself was written in the Edinburgh language Imp77 - Acorn actually had commissioned Imp77 compilers for both the 32016 and the ARM - and we recently found the full sources of the 3L ARM Imp (and Pascal) compilers at Edinburgh as part of our Edinburgh Computer History Project research!] It would have been a tremendously cheap second processor to build but Roger was quite set against the 6809 on the sole argument of clock speed. My argument was that it was a nicer processor and would have more high-level software than the 6502. Probably was true at the time although the 6502 did eventually get a whole slew of high level languages that I never would have thought possible. (I shared a house with the guy who worked on the Pascal compiler who I would occasionally give gratuitous advice to, and I also learned C while doing SQA of the C compiler) (quickly checks the web...) Well! http://www.stairwaytohell.com/atom/adverts/FLYER_Acorn_6809.png Never seen it in my life. It must have come and gone before I joined Acorn (I forget the year but it was post Beeb but pre-Electron) Other obscure Acorn kit that I have: the "Prophet" - a version of the Atom targetted at businesses. Never seen a single mention of it on the net. I have the Z80 second processor, various ARMs, I think a 286, a few 32016's - and a working ACW although it was having Beeb-side problems last time I tried it. Some day I'll photograph my acorn goodies and let you know what's available. Any cards I can put in a padded envelope and mail to anyone are fair game; the larger systems like the System 4 filestore and the ACW I'll be hanging on to. The atoms and electrons I could be persuaded to part with though they're easy to find anyway and I doubt you'd want mine. If anyone in the US has an Amercian Beeb (110V and NTSC) I'll be all over them to trade :-) - it would be a real boon for recovering the data from my boxes of 5.25" disks... Another project I did at Acorn was design a system for backing up hard discs to video tape. It used the teletext video chips (SA5050? - one of those SA chips anyway) to generate/decode a video signal. The actual board design was done by a new engineer who had been hired (Martin Gilbert) and was being broken in gently before being given any serious work. Hugo (file-system author) did the software. I believe the prototype actually worked but like most of my stuff at acorn it never made it to market :-/ Despite not contributing greatly to the financial success of Acorn, I have to say however that good times were had by all... it was definitely the best place I ever worked. G PS My main 'beeb' project before I transferred to VLSI CAD was the Teletext adapter. I found the source code recently if anyone wants it. I can't see Acorn giving me a hard time over releasing it after all these years...

PDP-11 Freeware CDs for RSX-11 and RT-11 (Originally Produced by Tim Shoppa)

by jhfinexgs2＠compsys.to

In regard to the Freeware CDs for RSX-11 and RT-11 that Tim Shoppa originally produced: I am in the middle of finishing a third (very small) batch of CDs and could easily add a few additional copies. I will be making all copies of the CD images from: ftp://ftp.trailing-edge.com/pub/cd-images/ http://www.classiccmp.org/PDP-11/RT-11/ http://www.classiccmp.org/PDP-11/RSX-11/ Since not everyone has both a high speed internet connection and a CD burner, I thought it would be helpful to make them available. If you have both requirements and are using Windows 98 SE / Nero Burning, I can help with the details if you don't know how to burn a CD from an "Image File". I have even been able to produce a label for each CD that is close to the original label from Tim Shoppa, although since they were scanned (THANK YOU FOR THE HELP), they are not perfect. They are available at $ 5 / $ 9 / $ 12 for 1 / 2 / 3 CDs. In addition, I understand that Memorex Black CD-Rs have a longer shelf life and are available at Business Depot. If anyone wants those instead, add $ 1 for each CD that you are requesting. Thus those amounts are $ 6 / $ 11 / $ 15 Please contact me directly for my snail mail address. I picked up some Memorex Black CD-R blanks and started on the copies for those who have already requested that a Black CD-R be used. Please include your mailing address!!!!!!!!!!!!!!!!!!! In general, I will regard any funds you send as a gift so that if anyone really can't afford the CDs, please state why that is so. Outside of the US, probably about $ 2 should be sufficient for extra postage. All amounts are in US dollars. Please ask if you are not in the US. No point in converting twice. In addition, probably most people do not follow the exchange rate between the Canadian / US dollar, but the current rate is MUCH less favourable. If a 4th batch is ever made, the amounts to be sent will need to be changed. I will keep the amounts the same this time, but the $ 12 will become $ US 14 and the $ 15 will become $ US 18 based on the current exchange rate and adjusted at the time if the exchange rate changes again. Sincerely yours, Jerome Fine -- If you attempted to send a reply and the original e-mail address has been discontinued due a high volume of junk e-mail, then the semi-permanent e-mail address can be obtained by replacing the four characters preceding the 'at' with the four digits of the current year.

8250 LP Double disk drive for the commodore 64

by semlj001＠hotmail.com

The drive on http://www.zimmers.net/cbmpics/deieee3.html is what I'm looking for. I've had a chat to my dad who's said that the technician said it could be one of 2 things. 1. The head moves & is attached to a wire. A connection in the wire could be faulty. He said that fixing the wire was niot an option for some reason or other but I guess we could replace the head. Can I replace the head with one from a different model? If so, which are compatible? 2. There are 3 main chips on the mainboard which seemed to be running hot. The guy replaced 2 but didn't have one to replace the 3rd. I have been chatting with another guy who has said that the 8250 drive is functionally the same as the 8250 LP so if anyone reading this has either for sale please let me know. Lance. ----Original Message Follows---- From: Ethan Dicks <erd_6502(a)yahoo.com> Reply-To: cctalk(a)classiccmp.org To: cctalk(a)classiccmp.org Subject: Re: Fwd: Re: Fwd: Re: 8250 LP Double disk drive for the commodore 64 Date: Wed, 2 Jul 2003 20:03:41 -0700 (PDT) --- Lance S <semlj001(a)hotmail.com> wrote: > Ethan, I'll find out the part that the technician thought was suspect. > If I haven't explained myself clearly enough, the 8250 LP is a double > disk drive that connects to a commodore 64. > > Thanks, > Lance. Looks like this: http://www.zimmers.net/cbmpics/deieee3.html Right? We are all talking about the same thing, but the drive by itself hooks to a PET. Your father must have a cartridge for his C-64 that provides an IEEE-488 port. One possibility is if you can't find an 8250LP is to get a regular 8250 (using the same connection). Dunno if an SFD-1001 would work or not... the DOS is not the same, so if your father's application depends on certain features of the drive itself, it might or might not be a reasonable substitute. There was a discussion about 8250LP repair on the CBM-Hackers list last year. This article is interesting: http://www.softwolves.pp.se/misc/arkiv/cbm-hackers/6/6731.html It suggests that the "fragile" part is a 6530 - a part made by Commodore that was always customized for its particular application. I've seen them on the KIM-1, in many Commodore disk drives and a few other places. Apparently some drives (perhaps the DOS 3.0 ones) used a daughter card in the 6530 socket with a 6532 (which is generic) and an external ROM. Dunno what's wrong with your father's drive, but if you can get in front of it, turn it on and watch for flashing lights. In many cases, that can narrow down the problem to a few chips. If it doesn't flash at all (i.e., it acts totally dead), that helps, too. Likewise if you can power it on, "talk to it" (read the error channel), but not read or write drives. Depending on the fault, it might actually be easier to fix than replace. Most "technicians" these days only know how to swap out entire boards or entire boxes. If it _is_ a 6530, that's kind of a problem... It's theoretically possible to fabricate a replacement, but I'm not sure the CBM community knows enough about that particular model to describe a functional replacement. A 4040? Sure. Maybe even an old-fashioned 8250. Not positive about the 8250LP. Cheers, -ethan _________________________________________________________________ Hot chart ringtones and polyphonics.

The main board is about the only thing that really is hard to replace.

The 1541 has half the tracks and half the heads (and less than 25% total space per diskette) Good luck in your search. All of my PET hardware is older than that.

It's possible to build your own with a VLSI I/O chip (6520/6522/6526) and a couple of buffers. That plus a ROM is what's on my VIC-20 IEEE adapter. IIRC, the drivers are a 75160/75161 pair, but there are a couple of options. AFAIK, there is firmware for _some_ IEEE adapter on funet. Not sure which one without looking. > I'd just get a couple of 1541's and daisy chain them together on the > port, along with the printer or printer adapter.

"The Mark-8 was an Intel 8008" was Re: I thought the Univac was expensive

by cb＠mythtech.net

>I have used other pics to sell something identical but I always mention >it. I >don't think that a problem generally. I agree that the simple fact of reusing pics isn't a huge issue. But he ALSO reused text... which also isn't a huge issue by itself (I bought a very nice Netopia router that simply used the info page from Netopia's web site, photo text and all). BUT... this guy slightly modified the text, in relation to the "value" of the unit. The original web site's text claimed the value at $12,000... he changed it to $17,000 on the ebay listing. So right there he is being less than honest. Also, which is the unit for sale? The Mark-8 or the 5100 precursor? The original web site seems to indicate they are two different units simply being displayed next to each other. But the ebay listing looks like it is trying to say the Mark-8 is for sale. All in all... I would have to think this is a bogus listing, or at the very least, a dishonest listing (ie: maybe there is a Mark-8 for sale, but it is probably beaten to peices and totally non functional) -chris <http://www.mythtech.net>

by dwightk.elvey＠amd.com

Hi Not all that use other pictures are trying to be dishonest. I came across one case where I recognized the picture of the item I'd bid on. I immediately wrote the fellow and asked what was up. I said that he didn't have a picture but he couldn't see any difference between the one he had and the picture. He was right, when I got the board, it was in great shape. Still, I told him that if you use another's picture, you should make a statement, such as "Looks identical to this unit" or something. Dwight >From: "Wayne M.

otrona parts?

I finally remembered to pull out my Attache 8:16 last night. There _is_ a serial number on the outside, under the right front corner, below the "Attache" name (mine is 7840). It's stamped on a small metal plate and glued in a shallow recess, so it could have been lost.

Composite video to TV

by r.mueller＠fz-juelich.de

I have tried this twice with some luck in both cases. In both cases the computer was an Atari 800XL. One monitor started as a Black and white TV able to operate from 12 volts or line power. It was easy because it generated 12 volts with a transformer when running from the line. The signal went into the contrast control, not the wiper terminal but the "hot" stationary terminal. If you have enough signal level this will work directly but you can try getting in before the video amplifier or simply put in a small amplifier between the new video input and the contrast control (trivial with today's fast opamps) You can steal the power from somewhere in the TV. The other case was more interesting because it involved one of those nasty TV s running without a proper line isolating transformer. Here I went to an optical coupler based on a fast HP model coupler for analog signals (I believe these reach 10 MHz with some effort.) I needed a tiny transformer to provide drive for the LED on the computer side of the optocoupler (the computer output is not enough). This was setup to use a slight bias current at zero input voltage from the computer and increasing light level (more drive to the LED) with increasing video level. The main trick in all this is some extra frequency compensation to delay the fall-off of the signal at the useful higher frequencies (you should preserve as much as possible at least to 6 MHz and even a bit more if possible). The receiving end of the optocoupler was configured to serve as an amplifier to get enough signal for the contrast control. The B&W version gave a quite good picture containing most of the sharpness you might expect from a proper monochrome monitor and I liked it much better than the green things I was using at the time with other computers. The color version with the optocoupler was fairly satisfactory and I was happy to use it when a color monitor was simply too expensive to justify. Text was adequately sharp at 40 characters per line. Don't forget, the color still had to go through a PAL decoder with loss of sharpness. Incidentally, PAL is inferior to NTSC for this kind of job because the fundamental idea of PAL is the mixing of two adjacent lines to correct for level dependent phase shifts in transmitted pictures. The idea is great for TV but poor for computer work. Narrow horizontal lines simply suffer from this mixing. Still, the overall result was "good enough". HOWEVER; PLEASE OBSERVE ALL WARNINGS IN EARLIER MESSAGES. These transformerless sets kill the foolish. If you live in 230 volt land, the risk is still worse. Bob

Reading PDP-8 paper tapes

by pete＠dunnington.u-net.com

A long-time acquaintance of mine (Graham Toal, whom some of you may know) has access to a collection of PDP-8 paper tape which wants reading. Unfortunately some of it is in the care of the Royal Musuem in Edinburgh, who won't let it out of their sight. Does anyone -- preferably in the UK -- have a paper tape reader that could be hooked up to a modern machine (eg a laptop) to read the tapes in the museum, and which they'd be willing to lend? To see what Graham and friends are doing, take a look at http://history.dcs.ed.ac.uk/ It's worth a look even if you're not interested in Edinburgh. I know Graham reads the list, so replies here or to me are fine. -- Pete Peter Turnbull Network Manager University of York

New finds: enough Torch stuff to sink a battleship

by julesrichardsonuk＠yahoo.co.uk

Hi Tony, > No idea... What (if any) chips are missing from your Stickleback, other > than the Ethernet chipset? I haven't had time to open the case today, but a glance the other day didn't show anything big around the VME bus interface; it looked to all be 16 pin chips and the like. I got an email from the guy today saying the following: [ Not a theory - I know that one is the original prototype. The VME interface [ didn't work on that PCB issue. I've an idea that it's got a prototype EPROM [ in it that doesn't require a key disk. IIRC on that box of Eproms I gave you [ there is a "Simon" eprom - that's a debug boot EPROM that doesn't use the [ key disk system Interesting. I noticed that Simon ROM and wondered what it did :-) > I thought that at least one of the monitors actually started by combining > the syncs to make composite sync (and thus you could feed composite sync > in on one of the pins). I will have to dig out the schematics... that could well be true - what I thought was a sync splitter board in that 725 turned out to just be some buffer circuitry; the output was still composite. How someone managed to blow the fuses for the RGB and sync lines I don't know... > The monitor I am thinking of is almost entirely a Sony chassis, with a > little Torch PCB at the input carrying the 8 pin DIN socket and > connectors to the monitor video board (flat in the bottom) and the speaker. that's what the 10" ones are like inside. I pulled the case the other day to see what the connections were but didn't need to go any further than the small PCB carrying the connector so I don't know what's lurking deeper within (yet) > I think that 'NC' pin is for the interrupt input from the touch switch. there's some bodged circuitry (cut tracks, extra capacitor and a desoldered resistor etc.) in the corner of the board near the video circuitry. Maybe that's something to do with the power-mechanism bypass (or might well be something else entirely) > Watch out -- if the NICd goes open-circuit, then the clock > chip might end up getting 12V.... nice! :-) [SASI controller] > One question?

There's a Torch ROM on the Xebec controller, but the machine was locking up with the Xebec board disconnected and just the SASI board in place. Unless the presence of the SASI board is enough for the machine to think the Xebec board's there too whether it is or not. No idea what would happen then... > The Torch _SCSI_ interface just has a normal sideways EPROM (SCSIFS) in > one of the Beeb mainboard sockets, BTW... Hmm. I need to open up cases again.

Modifying a B&W TV for composite video input

by ian_primus＠yahoo.com

I have read a lot about the SWTPC TV Typewriter, and I am interested in how people modified a black and white TV for a video monitor. I have an old black and white set that I thought would be fun to modify for use as a video monitor. Now, granted, I don't really need another composite monitor, I have plenty of old Apple monitors that will do the same thing, I just thought it would be fun, since it would be a challenge to find where to input the signal and how to do it. I found the PDF of part of the SWTPC TV Typewriter manual on a web site, and it explains the process, although not in great detail, and references a circuit diagram of what needed to be added, but the diagram is nowhere to be found. Does anyone have any instructions or hints that they may be able to give me? Has anyone done this before? Any advice would be appreciated. Ian Primus ian_primus(a)yahoo.com

DSM (digital standard MUMPS) + 9 track tape units

by luc＠e2t.be

If you are looking for a tape drive I might have some... I am just back from my old stuff warehouse, looking for this DSM tape... At the moment I did not find him - I am sure I have it somewhere but the place starts to look like a junkyard... I have to get rid of some old stuff I have in multiples.... Concerning tape drives: I think I saw there: 1 Kennedy 9300 tape unit (could not move, too heavy) 2 Kennedy 9000 tape units (45 inch/sec units 800/1600 bpi) 3 or more Kennedy 9600 units - autoloaders - I am not sure about the density they write plus all the service and maintenance manuals of this units and some alignment tools 2 Pertec autoloaders (I did not saw the manuals) 2 Digital TU10 units (this are real 800bpi dino's) - I am not sure about the controllers for this guy's (what kind of controller need they?) for this 9600 units I seem to have a PC controller too (a least one of them is connected to an IBM pc) As far as I know all units were working the day we put them out of order (somewhere in the early 90ies) (the TU10's might need some maintenance, I am not sure about them) I intend to keep a few units for myself (unless someone makes me an offer I can't refuse...) What's taking up a lot of place are all my decwriters... I have: 3 Decwriter I (output only) 5 Decwriter II consoles 4 Decwriter III consoles They might need some maintenance - I 'll check them and repair them if someone is interested... something more recent?) I found a few very complete looking Q bus systems with 9-track controller (will be Emulex or Dilog I think) They are realtive new (a least for a PDP11) - it are mentec cabinets with mentec processor (11/73) 4MB on board, SCSI disc controllers and a lot of I/O I am sure they all have DSM on their drives. (I never used an other Digital OS) There is an utility in DSM that lets you make new distribution tapes, so if they start I can make as many tapes as I want (if I can find a few tapes somewhere...) gr.

Fry's Nightmares

by big_boy_toddy＠yahoo.com

I have been shopping at fry's for almost 10 years when I used to live in the Bay Area only 2 miles >from the Camino Real store, and also when visiting towns that have one near where I'm traveling. The purchasing experience at Fry's is really about a 8-9, if you don't need help. If however you do in a purchase or return, then the experience goes down to about a 2-3. It really is that simple. I go there, well educated on what I want, I don't have expectations of service (shameful that the world retail experience is pretty much like this, even Nordstroms is rather saddening these days) and I don't waste my time buying anything that has a reputation of bad quality. In other words, do your own research and extensive reading online before you go buy from Fry's. Oh, and if you get that far, you may as well check out www.pricewatch.com and other online street pricing systems, and buy online to save yourself the 30 minutes or more round trip drive and waiting in lines.

Alltronics (http://www.alltronics.com/computer_miscellaneous.htm) has a video-composite adaptor for $5: <quote> TTL TO COMPOSITE VIDEO ADAPTER Requires +12V (or +5V) and video, vertical drive, horizontal drive signals. Produces RS-170 type composite video output. Fully assembled with 74125 sync regenerator, 3 terminal regulator, 2N2222 transistor. Only 2" square. 92C024 $4.95 each </quote> It looks like the adaptor I used to have for my Osborne 1.

Communication error! While you where refering to the common (video game) switch boxes, John did mention modulators! they are usualy the same size (ok, the TI one is a true brick), but do what they are named, modulate the composite signal onto a TV carrier.

Help identifying Mostek machine

by dwightk.elvey＠amd.com

Hi It is always a fun project to write your own BIOS and get CPM running on these kinds of machines. I have brought up CPM on a couple of machines and find it isn't too hard. In some cases, I'll put a Forth interpreter on ROM for that machine. That way I can explore the I/O's for the machine and debug any assembly code before I expect it to work with things like booting a CPM disk. Dwight >From: Joe <rigdonj(a)cfl.rr.com> > > These sound like standard Mostek STD-BUS cards. The cards were available >separately so it may or may not be a Mostek computer. As luck would have it >(your's not mine!) I found some Mostek manuals for some of the cards today >along with some DRI CPM manuals. I haven't gone trough them yet but I'll >post a list after I do.

Info needed on Sun SCSI/Ethernet sbus card plus sun sparc2 FS

by jmd5＠earthlink.net

i recently came across 2 X1054A SCSI/Ethenet Sbus cards. I am having trouble finding info about the Ethernet connector. This is not a standard port configuration. Its quite small (measuring 1/2 wide by 1/4 inch tall) and its *D* in shape. Female. are there adapters? adapter cables? I have 2 of these and only need one at present. If anyone is interested in the other card its free. Just pay shipping. If I cannot use this, then both are free for shipping. i also have a sun sparcstation 2 with 425M hd (w/sled), some memory sticks (one stick is bad for sure) with a dual sbus video card (cg6?), floppy drive. the NVRAM is bad. i think i have a sun keyboard too. ss2 for $5 and keyboard is $10. plus shipping. this is *as is* no guarantees. located in glendale california jeff duncan

I got a HP9000 - now what?

by kd7bcy＠teleport.com

I picked up this huge HP box with half the case(plastics anyway) missing... I picked it up because it had a DomainRing card and other Apollo-like ports. I finally figured out it's an HP9000, but I'm not sure which one yet. The board is labeled A1421-66538. It has a 25MHz 68040 CPU. The HP-IL keyboard port is a neat touch. Does this thing use a normal VGA monitor? Looks like this one has a tape drive(DC600 tapes like my Apollos?), and two hard drives - one is a freaking big 5.25" FH like my Apollos, the other is HP SureStorageDisk 1000S+ 3.5" drive. I see 4 ISA slots, one has a DomainRing card. Will the other Apollo cards work there too? Any pointers to good HP9000 info(I'm still recovering from hauling this huge box in to do much searching right now - this thing is bigger and heavier than the Apollos! LOL, I though nothing could get bigger...) I think my iMac is intimidated by this huge box towering over it on the desk now... -- /------------------------------------\ | http://jrollins.tripod.com/ | | KD7BCY kd7bcy(a)teleport.com | \------------------------------------/

IBM 5285

by aeg＠paradise.net.nz

Hi All Another recent addition to my growing collection is, as the title suggests, an IBM 5285. It has a 12" display and dual 8" floppy drives. The separate keyboard is connected at the front of the machine by a large 25 pin connector. Originally passed to me as "working" the machine fired up to display what looked like a single ASCII code at the top centre of the screen and a column of blocks on the far right. The keyboard is laid out very much like a terminal keyboard and testing the keys the keyboard buffer quickly becomes full. This results in what looks like a series of memory addresses along the bottom of the screen. All the while the two 8" drives are merrily spinning away. I have one disk with the machine which when inserted in either drive fails to read or alter the state of the display. My initial thoughts were faulty connections. I took the covers off to reveal about a kilo of dust liberally spread around the inside. I cleaned each component carefully and replaced the boards. Now I don't get anything on the display and the drives still whirr around oblivious of disk or no disk... So... my questions are: 1. Has anyone come across this model before and is it a dumb terminal? 2. What checks would you suggest to solve the disk access problems? 3. Can anyone point me towards a repository of information about it? Thanks in advance Alan

more intel MDS-800s :-)

by rigdonj＠cfl.rr.com

Things are really starting to fall into place around here. I got my 3rd and 4th MDS-800s running today :-) I posted a couple of pictures, there's no text or links yet but here's the directories. <http://www.classiccmp.org/hp/mds800_3/> <http://www.classiccmp.org/hp/mds800_4/> (Yes those things under the counters are HP 1000s. I have three working ones so far but only two good power supplies. So far I have FIVE bad power supplies for them. I'm going to have to sit down and learn how to fix thm soon.) Here's a link to pictures and description of my first one. <http://www.classiccmp.org/hp/mds-800/mds-800.htm> Got my 3rd Series II machine, a MDS-230, working last week. Tomorrow I start on MDS-800 numbers 5 and 6. Number 3 and 4 MDS-800s had 8088 and 8086 emulators, the first two had 8080 emulators. I got 8x48/8x49 and 8x51 emulators with the last two MDS-230s and had an 8085 emulator with my MDS-235. Does anyone have any of the other emulators such as the one for the 3000 series bit slice processors or the (non-intel) Z-80 emulator? I'm also looking for a personality card for the 1702 EPROMs for the UPP 103 EPROM programmer. Joe

Great Flea Market Finds this wekend

by jrkeys＠concentric.net

While working the flea market this weekend a guy selling items near me came over at the close of business on Sunday and offered me all of this computers items for free. He told me to just pick out whatever I wanted !!! I ended up with 7 large boxes of goodies software (Windows ver 1.03 new never opened box), Apple IIe and related hardware for it, Tandy hardware, printers, and other items. I have not been able to sort it yet for a full list but will update everyone after I have a chance later this week. From another dealer out there I purchased some goodies for the Vic20: 8K Tam memory expansion cartridge by MSD inc., HesWare 5-cartridge module, Vic-1924 Omega Race cartridge, Vic-1212 Programmers Aid cartridge, HES C304 HesWriter cartridge, Vic-1929 Personal Finance, Vic-1920 Pin Ball cartridge. She sold all it to me for $1.75 :-) I picked some other game cartridges for other systems for 25 cent each also and several mousepads. Except for the heat it was a great weekend.

General Automation SPC-16/4x & HP PTP

by pat＠purdueriots.com

I managed to pick up a General Automation SPC-16/40 and SPC-16/45. Aparently, the /40 needs its power supply to be repaired :(. Does anyone have info on these things? Searching google doesn't yeild a whole lot. They've got fairly nice frontpanels, and seem to be 16 bit machines (and have some _real_ core ;-). I got a disk pack drive to go with one (Single platter 14" cartridge, a lot like a DEC RL01), but not too much else. I'd like to get at least one of them 'set up' to play with. Oh yeah, if anyone's interested in one, make me an offer. I *might* be willing to let one go if the price is right. I also picked up an HP paper tape punch that seems to be in less-than- working condition, I haven't even checked the fuse yet, so we'll see if I can get it working. They were even nice enough to leave 1/2 a roll of blank tape on it. Now all I need is a paper tape reader and card punch/reader...

finds

by rob＠indefinite.freeserve.co.uk

While away, I popped in a car boot sale, and picked up an Apple Mac LC III base unit for 50p! Never having had anything to do with macs before, and only having new PC and old BBC kit about, I'm a bit stuck at first base - I think I have spotted the video out (15 way D-type, and have seen converters for them!) but where on earth does one connect a keyboard and mouse? Internally, it seems like it might be complete: 80Mb SCSI hard disc, one ram stick (one free slot) 68030 processor (and an empty socket next to it???) is this right? I also picked up (also for 50p) a compaq slt/286 laptop (missing keyboard and PSU) and a Mitec 3030D, also missing PSU. As both of course have flat batteries, I've not poked at them much yet. If they are of interest to anybody, drop me a line! (collection/shipping at cost from Salford, UK.) Rob

New here... Looking for PDP 11 / RSTS help

I'm trying to set up a system with RSTS/E v9 and the version of Simh that supports DZ0: (DZ11) devices. (on http://elvira.stacken.kth.se) I have no problem building the system from the tapes (images)... that' s all fine. When you look at the HARDWR LIST (when you don't start timesharing) it sees the device (DZ0:) --but-- when I try to connect via telnet, I just get "welcome to the PDP simulator" and then nothing. I'm assuming that you have to set something, somewhere else, to enable the device. I've been though loads of RSTS/E manuals, and I can't figure it out. In my defense, when I was messing about with RSTS/E (and learning to program and such) I was 12 years old, and didn't have access to the hardware. I am the proud *owner* of a PDP 11/23, but my evil wife wouldn't let me transport it to England from Arizona, so it is in the custody of my friend in Phoenix.... Please help, if you can. I'm starting to lose sleep over this one. Oh yes, my wife did fill boxes with all sorts of stuff, like toilet roll and suave shampoo, so why my precious PDP 11/23 (and my TRS-80 Model II) had to be left behind I don't know. Women! Take Care, Mark Firestone

Device to reset power...

by healyzh＠aracnet.com

I'm getting sick of my DSL modem locking up on me. Some times it will be good for weeks on end, other times it needs to be powercycled every few hours. This seems to be one of those every few hours days :^( It is fairly easy to set my Firewall up to monitor and determine if the firewall is down. The question is, what would it take to get that Firewall to powercycle the ()#*&% #(*&% modem on it's own? I seem to recall seeing something that can be plugged into a Serial port, and you can send it signals to turn the power on and off on a receptical. Zane

Omron Programmable Controller

The only Omron plc's i saw used a cartridge to store the pgm. the "programmer" was actullay an eprom burner with cassette ports on it to store an offline pgm. if you plc has a removeable box with a connector on the back of it (cartridge) open it up and see if it has an eprom in it . if it does you'll need the omron burner to store a ladder pgm in it. do a search for Omron on the net and i am quite sure you'll find info on it (omron's web page may still have the plc line on thier webpage, an email to the company will tell if they still have manuals on it). sorry, i have never pgmed an omron - just a ge series 6 model 60 (yes i have the industral hardened ibm luggable and all the pgms) and the westinghouse pc-1100's (yes i have all the accys for those too as well as the star tech serial/computer cassette drive) Bill Message: 10 From: "John Allain" <allain(a)panix.com> To: <cctalk(a)classiccmp.org> Subject: Omron Programmable Controller Date: Fri, 27 Jun 2003 20:34:51 -0400 Reply-To: cctech(a)classiccmp.org I have an older one here, an Omron Sysmac SCY-P5R-30E with control panel.

otrona parts?

by rigdonj＠cfl.rr.com

I've been playing with the Otrana Attache that I found last week. Cute little machine. I think I might hold onto this one for a while but it's missing some parts. Does anyone have a parts machine or parts that they're willing to part with? I need the cross bar that runs between the handles, software disks and manual, hinges for the keyboard and I LIKE to find one of the 8086 processor cards for it. FWIW I took it apart and checked it this morning and I noticed something funny. The no serial number anywhere on the outside of it but inside EVERYTHING has the serial number on it. The INSIDE of the case, the monitor, both disk drives, the power supply, the sheet metal, etc are all numbered 4616 but there's no number anywhere on the outside. Joe

New DEC finds

by erd_6502＠yahoo.com

Latest haul (courtesy of the new 11/750 owner I'm helping)... o Qbus grant cards, including a single-height Intergraph "PCB518" o Dilog DU132 tape controller (Pertec I/O, TS11/TU80 emulation) o M7504 DEQNA (broken handle, no cab kit) o M3106 DZQ11 (dual-height) o M7546 TQK50 o A012 ADV11 (says "A/D for 1103" on the solder side) o M7810 PC11 (with loopback jumper for "punch" connector) o M7608-BP MS630-B (uVAX-II 4MB memory card) o M8639-YB RQDX2 o M7606-AC KA630-A o M9404 / M9405-YB Q22 Cable Connector o M7168 / M7169 VCB02 (QDSS) 4-plane graphics o M8739 KLESI-U ("Aztec Unibus Adapter Card") o M-LSI-DR11 PLUS ... so plenty of uVAX-II parts and a couple of interesting items. I have abundance of VCB02s, so if anyone wants to turn a Qbus MicroVAX into a VAXstation, I'm sure we can work something out (no mice, monitor cables or cab kits, I'm afraid). -ethan

Torch haul pictures...

by julesrichardsonuk＠yahoo.co.uk

OK, got a few captioned pictures of the Torch stuff up for those interested at: http://www.moosenet.demon.co.uk/temp/torchweb/index.html (the non-thumbnail images are around 640x480ish and between 50 and 100KB) I've been inside everything to do some initial checks - no obvious signs of damage and everything was pretty clean and dirt-free. Still need to test PSUs on a dummy load etc. before I try powering anything up though. cheers Jules ________________________________________________________________________ Want to chat instantly with your online friends?

There were a number of misfeatures including a very slow video card and a bus that couldn't handle faster chips than the 68k that was in it. I dumped a pickup truck full of 'em (7350's) in the trash after rescuing a bunch out of Concurrent in '89 or so. Couldn't give 'em away at Trenton. I had all the distribution software including RM/Cobol, Idris, and stuff. Later I wanted to get my hands on a Masscomp 5550 or so to replace it. Concurrent bought up Masscomp but getting the boxes was nearly impossible at the time and FreeBSD and Linux made the 68010/020/030 Masscomps less than attractive in a price/performance/size kind of way. They also needed heavy hot tubes like the early Suns did. There was an attempt to get Concurrent to build a 68020 version of the 7350 for Perkin-Elmer (since they split into two companies) and the 68000 would barely take a 68010... but the Versabus backplane had noise and timing issues when you tried to push it. There was even an XF/200? version -- with 16 (IIRC serial ports). I ran a news feed to the box at home with 2 80 meg MFM ST506 drives... Slow but it worked. Fed it with a Trailblazer Plus and later a T2500. Amazing, but I think the modem had more processing power. Now the video cards have more power than the CPU's did back then. Bill -- d|i|g|i|t|a|l had it THEN. Don't you wish you could still buy it now! bpechter@shell.monmouth.com|pechter@ureach.com

Reading PDP-8 paper tapes

Hi Pete! Just to introduce myself to the folks here; I was an Acorn system programmer for several years which is how I know Pete, and I subbed to this list a couple of days ago - although my interest here is actually in older stuff, I *do* have an absolute sh*tload of old Acorn systems and boards that I've been trudging around for years and I'll be glad to help with Acorn info when I can. Any of the Acorn kit that I have which anyone needs, they're welcome to it - I'll never use it again, I just wanted to save it from the dumper... (for example I have lots of those 32K system/atom memory cards that y'all were talking about earlier. In fact I have one of the System (4?) file servers sitting on our washing machine right now that I've been meaning to run up as soon as I can find my 110-240v transformer again!; I've restored several hundreds of my acorn 3.5" disks but am only very slowly restoring my 5" disks via a raw-read program that's a pain in the arse to use; I think that job will go faster when I get a real beeb set up with a serial line to my unix - again, the bottleneck is a transformer. I have one somewhere but it's mislaid! Oh - that, and no monitor :-) ) Anyway, yes, we have a significant collection of paper tapes which I used to use personally around '76-78, at which point they were donated to the Royal Scottish Museum. Unfortunately the curators won't let us take them off the premises now in order to read them, so we need to take a reader of some description into their warehouse along with a portable PC. Even a serial ASR33 would do, although it would be a heavy lift! We're pretty desparate here... We also have some older paper tapes in the care of the University computing service which *may* have things like the KDF9 Atlas Autocode compiler on them which we also would like to read, but the PDP8 stuff is the current priority. One of our volunteers, Chris Whitfield, went to visit Hans Pufal last year and recovered data from some PDP9 DECtapes, including the full source of Hamish Dewar's operating system for the PDP9/15. Incidental to that - you may be interested in this file: http://www.gtoal.com/grenoble/source3/8tran.000 Which is the source of the utility whose manual is here: http://www.spies.com/~aek/pdf/dec/pdp15/DEC-15-ENZA-D_8TRAN.pdf There's other related stuff in that same directory such as the source to PIP. We hope to return to Grenoble some time and read some more of those tapes. One of the tapes *MAY* be the mythical PDP7 "Decsys" OS. At least that's what's pencilled on the tape, and the university did own a 7 for CAD work... We have an RL01?? (maybe an RK05?) disk pack from the Wavepower Project's PDP11 which we think may contain "GUTS" - Groeningen University Timesharing System - an EMAS-like personal OS written by Harry Whitfield and his students in Groeningen. We're looking for someone in the UK who may be able to read it. The disk format is the same as RSX11 we think, but we'd be happy even for a sector by sector raw copy. We've restored the sources of several operating systems: EMAS - on ICL2900 and IBM/XA PDP9/15 operating system by Hamish Dewar 68000 O/S by Fred King Mouses for the Interdata/Perkin Elmer range by Peter Robertson and Chris Whitfield This is all currently visible on the net but hasn't yet been organised into a web site. I'll be working on the web site over the coming weeks; it'll appear one day at the URL which Pete mentioned above. (WIP is at http://www.gtoal.com/athome/edinburgh/ ) I recognise a few of the names here. To the rest of you - nice to meet you. I hope to stick around, although I'm reading this via the daily digest so won't be posting as frequently as most of you guys. regards Graham

New finds: enough Torch stuff to sink a battleship

by julesrichardsonuk＠yahoo.co.uk

> My guess is that you have normal XXX boards mounted in a non-standard > case. Possibly the case from some other Torch product. Yep, from some of the Torch docs I have, the case seems to be from a Torch 300-series workstation. These appear to have been the getting-more-familiar (!) BBC core with either a Z80 or 68k Atlas board attached and optional seperate disk cabinet. Seems like there was a stage in production where the disk ran via a controller in the expansion cabinet from a SCSI bus whilst the floppy used a seperate cable going to the controller on the BBC - not the 'SCSI floppy' type setup that my XXX has. >> wired to the back of the case though). There's also markings on the board >> for a VME bus connection, but no socket or associated circuitry. > > The VME interdace is a DIN41612 plug and a few buffers. AFAIK all > production machines had it fitted. fair call. Don't know why mine wouldn't, even if it were a prototype - if the circuitry's there on the card why not install the chips and sockets? Strange. > Yes, it's analoge RGB at TV rates + 2 syncs + drive for a piezo speaker. Ok. The Torch monitors I have all need seperate syncs - explains the RGB board in the Torch 725 machine, which essentially seems to be a sync splitter from the BBC's composite output. >> labelled 'video' - but as the case is a hack who knows... > It sounds like this case once took a BBC micro board... yep, that fits with my 300-series theory. > There's an 8 pin power connector on the stickleback. Is is connected to > anything other than the PSU and the battery? The touch-switch circuitry > is on the PSU board, and sends an interrupt over one pin of that > connector (I can dig out schematics/pinouts if you need them). *wanders off to check... Just PSU and battery. Connections as follows: ^- front of board GND o o +5V GND o o +12V BATT o o -5V +5V o o nc v- rear of board The battery is obviously wired to ground too. 12V from the PSU also runs to the battery via a lot of black insulation tape; I haven't looked what's under there yet... The PSU isn't a standard XXX PSU (which I do have one of; I see the touch-switch connections you're talking about) - this machine has a 100W Wier PSU in it, likely stock to the 300 series if that's where this case came from. [Torch "Hard Disc"] >> OK, been inside now - it is a BBC, with a Torch Z80 coprocessor. Torch SASI >> interface hooked up to the BBC's 1MHz bus, with a Xebec interface hanging >> off > > Are you sure it's SASI, not SCSI (not that it makes much difference. Yep it is - says so on the board :) I have the manual for the Xebec interface to which it plugs into and that's definitely SASI / ST506. There's not much to the SASI board as it turns out - see earlier post; most of it turned out to be comms circuitry for driving the modem and nothing to do with the drive interface. Far as the SASI side of things is concerned, it's just some octal buffers, latches and the like; only about ten LSxx ICs. I had some time to mess around with the machine earlier, armed with spare BBC for testing (which turned out to have an intermittant RAM fault so wasn't much use :-) Far as the Torch machine is concerned, it seems to have a power-on reset fault such that it needs break hitting after powering up (I swapped the Torch keyboard for a real BBC one so at least my keypresses make sense). That shouldn't be hard to sort out. Now, without the SASI controller plugged into the 1MHz bus, if I unplug the Z80 board I can at least get the MCP to drop into the 'no Z80' condition where it gives an error message. I can't get that if the SASI controller is present (whether I have any combination of Xebec board & hard drive present or not) - just the MCP test on the screen and a flashing cursor. I'm curious why I don't see any disk activity at all, like it's not even trying to access the hard drive (ditto replacing that drive with a known-working unit, just with no valid data on it). Maybe the Xebec interface is faulty... [ Torch 725 ] > Definitely not a Quad-X nope :-( I'm quite amazed Torch could produce so many different boxes all based around the same BBC / Z80 / 68k choices though :-) >> Information on what exactly a Torch Unicorn was would be useful, to be >> honest. > > I thought it was a 68000 coprocessor for the Beeb.

I do have the programming guide and the spec (which I believe you said that you had), but unfortunately not the chip. I bet the guy I got this stuff from has a whole pile of them! [tape drives] > Oh, it just hooks up to the SCSI bus... It's getting the software sorted > out that's the problem. ahh, fair enough.

Although there are built-in definitions for common drives I get the impression it's all pretty flexible so just about anything can be defined. Parameters can be set for a given drive, including data rate (125/250/500KB per sec), number of heads (i.e SS/DS), bytes per sector (128/256/512/1024), sectors per track (0..244), cylinders (0..245), write precomp, step rate, head settle delay, motor on/off delays, starting sector number etc. There's also a parameter for setting the relationship between logical and physical steps, for e.g. formatting a 40 track disk in an 80 track drive. They actually look like quite nice boards... one of those in the PC could come in handy... cheers Jules ________________________________________________________________________ Want to chat instantly with your online friends?

Fwd: old hardware help requested

by vaxzilla＠jarai.org

DEC used a lot of these on it's systems. Their external TK50 drive: http://research.microsoft.com/~gbell/Digital/timeline/1984-6.htm Their BA123 style enclosure--the nameplates you see next to the power switches are separate pieces of plastic which snap into the plastic of the case, if helps at all: http://research.microsoft.com/~gbell/Digital/timeline/1985-2.htm http://research.microsoft.com/~gbell/Digital/timeline/1985-4.htm Their VAXstation 2000: http://research.microsoft.com/~gbell/Digital/timeline/1987-2.htm The base of their VT-240 terminal is another example, but I can't find any clear pictures of it: http://vt100.net/docs/tp83/full0303.jpg http://www.montagar.com/~patj/dec/ware/GRA_SOF_REF_GD_VT240_241_1984.JPG The one example I have on hand is on my VAXserver 4000-300, though mine's manufacture date is Feb 20, 1991. I can find confirmation, but I believe these were first being built a year or two before that time. http://www.jarai.org/temp/0629_001-sm.jpg http://www.jarai.org/temp/0629_002-sm.jpg http://www.jarai.org/temp/0629_002-sm.jpg There's also the VAXstation 3100 and DECstation 3100 series of computers. I couldn't find a clear picture, but here's a diagram for the back of the case used by those models: http://www.whiteice.com/~williamwebb/Chap2/DOC-2-6.html -brian.

Device to reset power...

> Can you toggle any line on any port (say one of the handshake lines on > the serial port (RTS, DTR) or one of the lines on a parallel port)? If > so, you could use it to drive a transistor and then a relay.. This is pretty much the kind of think that I had in mind, I'm sure I could build it, I'm just not sure how. At least the Sparc 5 I'm using has two serial ports (one is the system console). I've got to admit, I *REALLY* like Jay's idea of the APC Masterswitch, unfortunatly they look to be a lot more than I'm wanting to spend :^( Still, they would be *perfect*. OTOH, your idea, coupled with the 16-port Serial box I've got for the firewall could make an interesting setup. Eight ports for switches, eight ports for console cables :^) Assuming of course my OS supports the box. Zane

New finds: enough Torch stuff to sink a battleship

by julesrichardsonuk＠yahoo.co.uk

> This unit sounds /very/ like a Torch 68000 Hard Disc machine I have, so > definitely production quality. Same ridiculous separate power supply.. ahh - so there's one other out there at least then! :) Looks identical, but mine doesn't have the 68000 stencilling on the front of the case. The brackets securing the BBC board to the drive cage and the mounting for the UHF connector (where it plugs into the BBC board) look very improvised on my machine, but maybe that's the way they all were in production. > Mine appears to be complete - it has the modem (connects somewhere to the > torch boards, rather than the RS423 on the BBC, so makes 100% of all BBC > native communications software useless). yes, I just worked that out too; I'd found schematics for the SASI board which wasn't nearly as complex as what I have, then schematics for a mysterious comms board. Turns out that although it's labelled as a "Torch SASI board", the board also carries the control logic for the modem. Why the modem went walkabout from my machine I don't know. > 68000 board is positioned where the Z80 board is on yours, is just bigger. I don't think mine has the mountings in the right place to take either of the two flavours of 68k boards I have. > The barrel jack plug connector on your modems was indeed the standard "plug > and socket" telephone connector in the GPO days (before they became British > Telecom) and was not a mass-market commodity - you had to pay quite a lot > to have sockets installed; most phones were hard-wired. Hmm, I do remember phones being wired into the little box (typically) just inside the front door on houses before sockets became common. Seem to remember phones could only be bought from the phone company too. > My machine /seems/ to run a 68000 version of CPN - there is supposed to be > a unix for it, but I never found a way to boot it into that, or software to > reload it. I had a quick flick through some of the docs I have. They seem to suggest that you need the later Atlas 68k board to run Unix and CPN from a hard drive, and that the earlier 68k 'Neptune' cards wouldn't allow this. See what card you have (it'll say Atlas if it's the later card) - I've probably got everything needed to do a Unix install against one of those assuming any of the discs I have are still intact. > I got rid of most of my other torch stuff; the communicator tried to sell > for quite a high price on eBay.. makes me cringe to think of so many going > to landfill. I heard they weren't that common and a little sought after. Maybe some more will crop up at this guy's house... Is your machine somewhere where it's accessible? I'm curious as to what disk setup you have in your machine; whether it's a 1MHz - SASI - Xebec - drive configuration, a 1MHz - SCSI - Xebec - drive config, or something else entirely. Knowing what ROMs you had might be useful too in trying to work out how to get my machine to boot as at least I can try to duplicate a known-working configuration. And if you feel like getting your hands really dirty, pull the MCP ROM temporarily so that the machine boots to Basic and see if your keyboard produces sensible characters or not :-) (the keyboard mapping is all over the place on mine, but I don't know if it's supposed to be like that or not!) cheers Jules ________________________________________________________________________ Want to chat instantly with your online friends?

TRS-80 Model III - No Disk Drives

by alhartman＠yahoo.com

When the Model III first came out, it was Cassette only. and 16k and 32k Models (I have a load of the badges I ordered from National Parts that say 16k/32k/48k, because the Coco used the same ones). That is probably the catalog number for one of those. I can't put my hands on a vintage RS Catalog from those days, but I probably have one somewhere... When the Disk Controllers and drives came out, I had a friend that wanted one badly... I worked in a Radio Shack store at the time. We would get the National Parts Catalog every month, which would often list repair parts and kits in advance of the retail release. We ordered the Disk Controller and Drive system before it became available at retail and put it in ourselves. There was no manual, but it was pretty easy. We figured it out in an hour or two. He had one of the first 48k, 2 Disk Drive Model III's in Brooklyn. I had a fun similar story with my Model I Expansion Interface... I had bought it on layaway from my store and I was paying it off each paycheck. Radio Shack wanted an ungodly amount of money for the Ram upgrade to take the E/I from 0k to 32k. Something like $100 a set, plus installation. I found a company selling the RAM chips for $35 a set (I think), and ordered two sets (the amount of $75.00 sticks in my head. That's either the price of both sets together, or I paid $75.00 each for them...) Anyway... I took the E/I home as soon as the RAM came in. Upgraded it to 32k, tested it... And then brought it BACK to the store and put it back on the shelf. I paid it off a couple days later, and then took it home. I'm the only person I know who voided the warranty on a piece of hardware BEFORE I officially bought it... LOL!! Regards, Al

GREAT!!! I've been thinking of you lately. Charlie Hedbring has been asking about you...

He's going to bring his Corvus from NYC to Saratoga and next month I'm going to drive up and set it up for him. I still have a load of Corvus stuff in my closet I got >from Stewart Newfeld to sell for him... I have to inventory it one day and get it into good hands... > Hope all's well with you.

to Jeffrey Sharp Re: Jeffrey Worley

by tedtace34＠netzero.com

I saw your entry that seems to be about a year old about Jeff Worley. I thought it was odd that you refered to him with the handle Technoid. The Jeffrey Worley I knew from High school ('86-'87) in Miami went by "technoid mutant". I'm wondering if this is the same person I know. if so, I might have some disturbing news about Jeffrey. Please let me know if some of the information I have presented here seems to Jibe with who you knew. Ted Hubbart

cctalk digest, Vol 1 #664 - 5 msgs

by sml49＠attbi.com

I've acquired a whole collection of assorted LC-series machines from my town disposal area - and they almost invariably work as-found, needing a little physical cleanout and maybe a new motherboard battery. I had a Performa 475 running as a web server for awhile, figuring it didn't consume much juice and was relatively quiet but it's been replaced with a Performa 6300CD, a dog of a machine design-wise but adequate to serve up a single page of family photos. I've got a tub of LCs now, plus some parts and whatnot from a few I cannibalized; if anyone needs any perhaps I can help out. One of these days I'll network them all and run NetBunny just for a lark - let the bunny march from one screen to the next. (It's been rainy here lately - I need to get out more.......)

Device to reset power...

Eight ports for switches, eight > ports for console cables :^) Assuming of course my OS supports the box. That's pretty much how I've done it in the past. You could also use a parallel port to drive several relays. One slightly simpler method I've used is to employ a photvoltaic/solidstate relay. Something like the Omron GVM series will switch 350VAC and currents of about 0.1A (which should be fine for your modem), or the International Rectifier PVA2352N will switch 200VAC at around 0.14A. The Omron ones need about 10mA drive at 12V, the IR types typically 5mA, so you can normally drive them directly from a serial handshake line, and they come in a DIL package the size of an 8-pin device. Cost about UKP6, so I guess about US$10 or so. They're MOSFET devices so they can be used to switch DC as well as AC. There are some other devices that will switch a couple of amps, or even more, and still only need 10mA drive, but they tend to be encapsulated hybrids and take up more room. They also tend to be thyristor or triac units, so best restricted to AC. I've never used them, but Crydom do some devices at about the same price as the small Omron SSRs, except they switch up to 5A with a control current that could be as low as 3mA; however they're bigger and use a triac. One thing to think about is whether you want NO (normally open) or NC (normally closed) operation. Do you want the power turned off (disabled) if the controller is powered down or removed? -- Pete Peter Turnbull Network Manager University of York
