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.

Modifying a B&W TV for composite video input

by Robert_Feldman＠jdedwards.com

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.

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.

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 :-)

Things are really starting to fall into place around here.

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

by nedry＠mail.bedlambells.com

I'm new to this fine place, but not so new to retrocomputing... I had a question... I wonder if any of you know the answer... I'm trying to relive my misspent youth, spent hacking into the RSTS/E system at Arizona State Univerisity. 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...

by healyzh＠aracnet.com

> 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.

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

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
