Radio Shack Wire-Wrapping Tool

by healyzh＠aracnet.com

A week or two ago I expressed my doubt that you could still get Wire-Wrapping tools from Radio Shack. Well, I got one on Sunday, so I figured I'd share the part number since the stores ar clueless for the most part (I was dumbfounded to find someone that more or less knew what I was talking about). Wire-Wrapping Tool P/N: 276-1570A It's one of the little ones that looks a little like a Jewelers screwdriver, and it cost a whole $7.49 so needless to say I was just a little bit happy.

EPROM Folly (was: Re: Discontinued IC's:...

* Basically, it's an FAMOS-based EPROM chip in a plastic package and can be * programmed by a regular EPROM programmer - but as it's got a plastic * package, it can't be erased or reprogrammed (hence the addition of OTP) - * If it can't be erased or reprogrammed, why not just call the damn thing a * PROM?????????????????? Two ways to erase: 1. Just wait a long time. The bits will start fading after a few decades, maybe in a good chunk of a millenium they'll all be set back to the factory state :-). 2. X-Rays.

Another reason to preserve systems

by rdd＠smart.net

Greetings, A short while ago, I just thought of yet another reason to preserve computer equipment, particularly that which is the most durable. While doing some research for someone else pertaining to application service providers (ASPs) - which I don't like, I began thinking of things mentioned by Sun and Microsoft that give me the creeps: the thought of programs, applications, operating systems and, worse yet, one's own data, aacessed by, and stored somewhere on, the Internet, not locally. A user would have no control over one's files. If enough people will be foolhardy enough to fall for the marketing hype, and begin using "network appliances" instead of computers, 10, 20, or 30 years from now, will home computers with local mass storage even be sold, or be legal to own, for that matter? After all, we know what mindless sheep most people appear to be when it comes to following the herd and not thinking for themselves. BTW, what I've been researching is the danger of the use of ASPs for medical claims processing, and when one begins digging into this, one begins to see the commercial and governmental interests involved in people's medical records, and it's not nice. There's the problem with non-objective medical information presented by web sites such as WebMD/Healtheon (which also want to process medical claims as ASPs) due to conflicts of interest who have advertisers and shareholders to consider. For those in the US, some may be surprised when they learn the realities of HCFA and the HIPAA, and how much privacy they stand to lose by laws promoted by certain politicians (including the president) as increasing privacy, when they really do just the opposite - not to mention the temporary moratorium on national IDs for everyone to be used for medical purposes, ...then there's the work towards the creation of a national database for medical records. I won't even begin to touch on such areas as the commercial and governmental influences involved with the A.M.A. (no wonder many physicians don't belong to it!) and conflicts of interests that affect nonpprofit web sites such as Intellihealth (look into its connections with Aetna, and what Aetna has done to people's health with it's HMOs) and Medem. Before anyone flames me, please look into this yourself if you value your health and the confidentiality of your medical records... then express your concerns to your physician. -- R. D.

microfiche and scanning

by jim＠calico.litterbox.com

Since y'all are talking seriously expensive hardware ($50,000 and up), here's a much cheaper thought. Get a photographic enlarger and hack the film holder to hold the fiche, then blow the fiche up optically to 12x17. This quadruples the size and thereby reduces the necessary reslolution from 5000x5000 to 1250x1250, which a top end consumer scanner or midrange pro scannershould be able to do. The scanner may set you back a thousand dollars or more, but the other 49,000 buys a lot of photographic paper and chemicals... -- Jim Strickland jim(a)DIESPAMMERSCUMcalico.litterbox.com ----------------------------------------------------------------------- BeOS Powered! -----------------------------------------------------------------------

Switch-Mode PSU Failure Modes, Repairs, & Parts Substitutions

by dhquebbeman＠theestopinalgroup.com

Good Morning, I hope everyone had a great weekend, I sure did (not Classic-Computer related so I won't bore anyone with the details)... Subsequent to my first post about my Prime PSU, Don Maslin sent me a howto on repairing switchers, that was written by Keith Lofstrom. The howto is fairly comprehensive, but does assume that most repairs are taking place due to bad PSU design. I'm not sure mine failed due to bad design. It was dusty, and after I removed it, I found that the 2455 cabinet has an interestingly-design set of airflow guides that's above the cage; it's basically a sheet of thick plastic with holes in it, so that the dual-squirrel-cage blower dumps air into the cage through these holes. While there was some airflow, once the PSU was out, I could see that many of the holes were clogged up with dust and lint, and thus I think the PSU simply overheated inside the cage. One additional data point that I thought I'd mentioned, but may not have, is that: The system was up and running fine, no evidence of any problems. I shut the system down that night, and then the next day when I turned it on, I got nothing. I did not see any evidence that the PSU briefly came on and then died; it simply never came on. >From what I've gathered from the comments posted about switcher operation, and from Keith's howto, it seems like something failed that is part of getting the secondary supplies "jump-started" to an up-and-running state. So, as long as it was powered up, it would continue to operate. But once I turned it off, the portion of the PSU (something between the primary and secondary supplies? Something like that big power resistor, maybe?) that gets the secondaries going, couldn't get them going. So, has anyone else been in a similar position? Do I have a fair chance of simply replacing the parts I've found that failed, reinstalling it, and being successful? There is a 5v adjustment that needs to be made before bringing the system up all the way, and while I hate to use the system itself as a dummy load, I don't have the Prime bus pinout, so I can't easily determine what's what. One of the things Keith discusses in the howto is about parts substitutions. Most of his comments are w/r/t transistors and the like, and he suggests using as replacements devices that have voltage and current capacities that are increased over the part that failed. He goes on to say you need to test each such substition with a curve tracer before finalizing each such substition. However, I don't think any semiconductors failed for me. He says that in a good design, there are some power resistors protecting the switcher transistors, and from my examination to date, it appears that Prime did in fact put these in the design. I'm going to remove the other 3 of the 4 that are in that area to be sure whether any did or did not go open-circuit, as there is significant thermal discoloration of the underside of the PCB in that area. How reasonable a course of action is this? What's likely to happen should a problem still be present? I'm thinking that worst case, the parts that failed will just quickly fail again, putting me back at square one. As always, thanks in advance for any help y'all can give me! regards, -doug quebbeman

Whatever happened to the Flat-Pack (was Re: Discontinued IC's)

TI has previously sold the IP and remaining dies for end-of-life > parts to other firms who then either continue production or package the > dies to meet military needs -- which is great if you need something in > a flat-pac... Whatever happened to the flat-pac? It seems to me to be a package that has many of the same advantages of modern SOIC's, but maybe 30 years ahead of its time. Was it a manufacturability issue? Was it a "proprietary" issue? The flat-pacs I worked with were ceramic or ceramic/gold, but it seemed pretty straightforward to me to do the same thing with plastic. Am I wrong? Besides, many of the flat-pac pinouts were different than the DIP pinouts, and this was actually a good thing in the case of many TTL IC's which had power and ground pins in weird places... It seems to me that in most cases SOIC IC's follow the DIP pinout (though I'm sure there are exceptions.) Tim.

Scanning microfiche?

by CLASSICCMP＠trailing-edge.com

Not so much related to classic hardware directly, but instead the *documentation* for classic hardware *and* software: OK, let's say I've got a couple thousand sheets of microfiche, 4" x 5". Each sheet contains ~200 paper pages of text and drawings. I want to digitize at least part of this, possibly OCR'ing it too. Each 8.5" x 11" printed page on the microfiche is about 0.15" x 0.2", so the magnification factor is about 50. That means if I want the equivalent of a 75 DPI scan of the full-size version, that I need to scan the microfiche at about 4000 DPI. The el-cheapo (i.e. a couple hundred $) scanners I see on the shelves here seem to top out at 2400 DPI. And 4000 DPI is the "minumum acceptable" number in my above calculation. If I can do 4 times better than that, so much the better. In my experience most 75 DPI scans of 8.5" x 11" text don't OCR well at all, you need more resolution. So what are my choices for higher-resolution scanners? My *other* hobby happens to be large-format photography, so if the resulting scanner is also good for 4" x 5" negatives and/or transparencies I won't complain :-). It looks like there are 35mm film scanners with 2700 or 3000 DPI resolutions available for a few thousand, but I think I need to do better than that. Of course, I can go in the darkroom and enlarge the microfilm, but doing that for each of the thousands of sheets is going to be tedious. Yeah, I know, it's already a tedious job! Finally, do *any* scanners have documented interfaces? i.e. say I find myself a nice SCSI-connected high-speed high-resolution scanner. Am I going to be reduced to point-and-drool with Windows 98, or can I actually hook the scanner up to a real computer? We're talking about many tens or hundreds of gigabytes of data here, so I'm willing to invest some effort to automate the acquire/compress/archive process. Tim.

I'm a little surprised that some digital casettes were manufactured using the sonic-welding technique, instead of using screws to hold together the shell halves. FWIW, they do make digital cassette with screw assemblies. And yes, as you've discovered, digital cassette tape is the same width as audio casette tape. The differences are in the oxide formulation. Digital casette tape needs little in the way of frequency response, and the response curve should be as flat as possible, whereas (IIRC) audio casette tape tends to bump up the low and high ends. Also, digital tape needs a very low dropout rate, so they end up with a more uniform oxide coating. And, I've never seen them use metal or chromium dioxide for digital cassettes. Lastly, the substrate needs not to stretch, so long tape lengths are out. regards, -dq

SCSI settings HP 7980 S tapedrive

by wanderer＠bos.nl

Does anyone know how to change the SCSI id settings on a HP 9 track tapedrive model 7980 S? It's current setting is 3 but that is conflicting with my disk. There is no thumbwheel and there are no visible jumpers to find.

Need Thermistor Cross-Reference

by dhquebbeman＠theestopinalgroup.com

Hello, I need a cross-reference for a part which Tony has identified as a thermistor; it carries the printed designation MCI 307138 and that's it. I found a company called Midwest Components that makes a line of thermistors they call Thermodisc, but after contacting them, they indicated that this was not a part of theirs and might not be a thermistor. As an alternative... There is an undamaged one on the main board. If I remove it, can someone suggest a way to determine its specifications by use of a test circuit of some kind? tia, -doug quebbeman

I think it would be possible to stick > them together again. How wide is the tape? If it's not too narrow, you could try 1/2" audio splicing tape (thin self-adhesive mylar tape, usually white or yellow). The technique is to butt the two ends together, tape over (the non-oxide side!) with the adhesive tape at right angles to the tape, and trim with a razor blade or fine scissors. For 1/4" or bigger magnetic tape, I usually trim the join very slightly narrower than 1/4" to help prevent binding. I've done this successfully on compact cassette tape (1/8"), microcassette tape, and 1/2" magtape and VHS video tape -- the latter usually to put the leader back on if it's snapped. > No, I wouldn't trust the result for very long, but it might be good > enough for me to recover the few files on said tape that I didn't manage > to read before it broke... -- Pete Peter Turnbull Dept. of Computer Science University of York

Scanning microfiche?

by CLASSICCMP＠trailing-edge.com

* Assuming you're scanning old DEC fiche, might there be a way * to reduce the cost by making the final electronic copies * available for sale to others? It might also make sense to * put the collection online and sell subscriptions or one-shot * looks to view it. Or does Compaq refuse to allow * redistribution of these old docs? There certainly isn't any problem with distributing *existing* fiche. The problem comes with new copies, especially when the copies get distributed. What I'd like to do, as a first step, is to take the fiche with all the pocket service manuals and get those onto CD-R in some form. Then work out a deal with DEC so I can give away those CD-R's just like I give away PDP-10 and PDP-11 DECUS freeware CD's. I don't want to make any money off this, and in fact I think it'd be wrong to make any money off it :-). Tim.

Scanning microfiche?

by CLASSICCMP＠trailing-edge.com

*>As for the $0.07 per page, maybe Tim should indeed buy his own scan/copying *>machine for many thousands of bucks. Well, I already do have a fiche viewer, I was just looking at a way of making it more widely available, and making it digital, with the intention of putting it on modern/denser digital media as time goes on. I can duplicate/enlarge the fiche in my darkroom, the material cost for a duplicate 4"x5" sheet is about $0.50. The stuff prints onto conventional photographic paper really nicely, although at about $0.50 per 8"*10" print it isn't cheap to do even a single sheet of fiche (somewhere between $50 and $100) photographically. Those Xerox-machine based page-printers are the real winner costwise, though I'm not real happy with the printed pages I've had made for me in the past quality-wise. As to the quantities, there seem to be about 250 fiche sheets in a one-inch stack, and my stack is about 18" high. That's 250*18=4500 pieces of fiche. And each piece of fiche is somewhere between 50 and 200 printed pages of text; that's about 450 thousand printed pages, by my calculations, using an average of 100 printed pages per fiche. In my experience, a 300 DPI scan of a page of text or line drawings reduces down to about a 30 Kbyte GIF. As Eric pointed out, there are more efficient ways to compress images, maybe 10Kbytes is reasonable. 10 Kbytes * 450000 pages = 4.5 Gigabytes. So it'd fit on a 8 or so CD-ROM's. As a smaller sub-example: The stack of fiche containing all the PDP-11 related pocket service manuals (CPU's, boxes, terminals and peripherals) is only about 45 pieces of fiche. They're packed pretty full, so that's about 10000 printed pages. They'd all fit nicely onto a fraction of single CD-ROM, by my calculations, even if it was as crude as a 30 kByte .GIF per page. OCR would be nice for keyword searching, too... * I would certainly kick in $1K toward such a project. My experience is that * you _have_ to have an auto scanner, this move/frame/press stuff is just too * hard to keep your brain focussed. I was thinking (I could be wrong) that a scanner could take in the whole 4" x 5" microfilm sheet at once, and then I could write some software that would parse the whole-sheet image into frames, do some automatic cleanup on each individual frame, and compress. Am I walking down the wrong path? Tim.

Tony, if you can't view the JPEGs that Sellam put up, I can tell you that they show: the L-PEN socket is a 180-degree 5-pin DIN the TV socket is a 6-pin DIN the A-CMT socket looks like an 8-pin DIN (same form factor as a 7-pin DIN) the RS-232C socket is a DB-25S the socket on the back of the FDD card is a 34-pin 3Com header, like the ones on a Beeb the socket on the back of the C-CRT card is single-in-line 18-pin connector, looks like about 0.1" pitch, male pins, green shroud with male pins, keyed by having cutouts in two corners (in the same way a 64-pin DIN header is keyed) -- I can't remember what these are called but I've seen them before. -- Pete Peter Turnbull Dept. of Computer Science University of York

Any sources for used raised flooring?

I got mine from someone (in the UK) who clears commercial/industrial buildings before they're reused or demolished. It was very cheap (compared to new prices) but there was a fair amount of work involved in cleaning the glue off the old supports, checking all the screw threads, cutting the supports to the right length [1], sorting out the damaged/warped panels [2] and those that were slighly odd sizes (mine are nominally 600mm square but a few turned out to be 590 x 600 or 610 x 600, presumably for edges). And don't forget that you need different supports for edges and corners, for most types. BTW, the same source I used had lots of fancy lighting fittings, suspended ceilings, air ducting and fittings, electrical fittings (including floor boxes), doors, etc at knockdown prices. Since there's a lot of metal in the supports, and the panels are normally steel-clad, you might indeed find something at a scrapyard, as Sellam suggests. One of my friends got secondhand flooring from a university that was moving its computer room. Ask around -- I've heard of places that take up the floor and fill it in with concrete screeding to reuse the room. If you can make your want known before that happens, you have the opportunity to remove the panels and supports. If you get second-hand flooring, mail me for tips. I now know more than I really wanted to about the do's and don't of secondhand computer floors :-) It *is* worth doing, though, if you can find some. I'm really pleased with mine now it's all done. [1] You might not have to do this -- my floor had originally been raised about 20" high and I only wanted a little over 6". [2] The panels are pretty heavy, and if not stacked sensibly -- mine were in 8' high stacks -- they have a tendency to warp over a long period of time. Warped tiles mean uneven floors or tiles that rock slightly. -- Pete Peter Turnbull Dept. of Computer Science University of York

Yes, some HP scanners, U-Max, Mustek, Plustek, and a few others are documented. You should probably look at the SANE project (Scanner Access Now Easy) which runs on various flavours of Unix (and there was a WinSane project under way last time I looked, but you asked about real operating systems so I won't mention it :-)). http://www.mostang.com/sane/ is the homepage, but it doesn't seem to want to talk to me just now, so you might try ftp://ftp.mostang.com/pub/sane/ or http://linux.com/howto/Hardware-HOWTO-22.html -- Pete Peter Turnbull Dept. of Computer Science University of York

Remote Services Consoles REVEALED!

by cmcmanis＠mcmanis.com

:-) I found DEC document EK-KCRSC-FS-001 "Remote Services Console: Field Service Manual." Sometimes I'm sure God is a computer collector. Connections: Connector Local Console Terminal A1 CPU Conole Port A2 Optional to Comm port B1 Connection to modem B2 Now the way it works is it can use the modem from an existing dial-in line which presumably the customer would already have. So where you would normally have: Console >-------------> Computer Modem >-----------==> Comm port You get +---+ Console >---+ R +------> console | S | Modem >----+ C +------> comm port +---+ This lets the modem be used to dial in the console or on the comm port when not remotely diagnosing issues. Buttons on the front control baud rate, the mapping is: out out out 300 in out out 1200 out in out 2400 out out in 4800 in in in 9600 Baud T is the terminal and should match the console port setting Baud M is the modem (1200 baud preferred :-) The various modes: REMOTE - modem can dial into the console. Light blinks when no one is dialed in REMOTE USER - modem is connected to the comm port USER PORT - all operation is transparent console and modem connect "straight through" to the other connector LOCKOUT - modem can't be used to get to the system. The dial in line uses the DDCMP protocol to insure data integrity. I'm not sure what this means in terms of being able to dial it from a PC. --Chuck

I've seen boot blocks that contain enough code to print out a message that you've tried to boot a data disc. Trying to boot an unformatted disk in such a machine will likely result in the endless seek. Eventually, manufacturers moved that functionality into the ROM/BIOS code, but in the PDP-11 days, you could boot a system by writing bits manually into device registers to initiate a transfer of the first part of the disk into low core. I used to know the exact ODT sequence to boot an RL-11 in an 11/24 because I didn't own RL02 boot ROMs. It was about three or four commands. It worked because it takes a human a finite amount of time to enter in all the commands and that gives the drive time to read the block between, like, the third and fourth steps, removing the need to write a boot block that initiates a transfer and loops until the controller shows that the operation is complete. It all comes down to how smart you want the machine to be at boot time versus how flexible you want the booting scheme. -ethan ===== Even though my old e-mail address is no longer going to vanish, please note my new public address: erd(a)iname.com The original webpage address is still going away.

Scanning microfiche?

by aek＠spies.com

If you have 1000 sheets to scan, there are services that do this for around 6 cents / scanned frame on the fiche (prices vary on resolution). I had some samples made from a few DEC fiche, and 300dpi effective is the MINIMUM scan that is usable. Because of the thousands of sheets of fiche that I have, I'm thinking of buying a Canon fiche viewer/scanner in early fall (around 10K). If you have DEC fiche that you're thinking of scanning, you may want to check with me before spending any money on having yours scanned.

BIT90

by guerney＠bigpond.com

I picked up a BIT90 today. I have never seen one before other than on a couple of computer museums on the web. Unfortunately the unit came into the thrift shop as the bare system unit, no power supply, nothing else at all. I would appreciate any information on power requirements and power pin out (a compatible power supply from another micro?). I know it takes ColecoVision cartridges from www.zock.com/8-Bit/D_Bit90.HTML, which is the best site I have found (out of just a few in all). Thanks Phil (Brisbane, Australia)

Mystery board: 4MB memory marked "GS-2" by DEC?

by cmcmanis＠mcmanis.com

Anyone know what a memory card marked "4 MB Memory Option" built by DEC with the number 5419051-AA and 5019050-01 A1-P2 on its edges might go to? Would anyone care to have it? (it doesn't seem to be a VAX memory board at all) --Chuck

PDP 8/E partially restored

by lemay＠cs.umn.edu

Well, I have my PDP 8/e partially restored. I realized that I had the correct replacement bulbs for the front panel 'in stock', in that I obtained a bunch of used ones in some junk DEC peripheral parts earlier this summer. Is this dumb luck, or just the Computer Gods manipulating Fate again? Obviously, I'm a man of Science, so I'm leaning towards the Computer Gods scenario... All the panel lights are working, except the least significant bit (switch 12) on the lower display. There is some evidence that someone has replaced an IC on the front panel display board sometime in the past. I have 8K of core installed and I'm running the "initial operating check" from chapter 2 of the maintenance manual. So far so good. Does anyone have any small test routines that I might toggle in to futher test the core? I did switch in a different M8310/M8300 set, and that one panel light is still dead (and obviously I tried 2 working bulbs before i proceeded to more complicated stuff). Stuff I still need: 2-3 yellow switch handles, and possibly one switch to replace the EXTD ADDR LOAD switch someday. that switch does work, but it doesnt feel at all right... Also, I need some serial cables, as i dont have a single one... And I still want to find a supplier to buy some new front panel lamps from, at a reasonable price... I think I bought a PDP 8/e,f,m small computer handbook once, so I better go look that up! Anyone with a good suggestion on how to printout the small scans of that book thats on Highgate, so that it wills a Letter size sheet of paper, should contact me ;) -Lawrence (extraordinarily pleased with himself) LeMay

Sad day...Jameco discontinues 6502

by rcini＠optonline.net

Hello, all: I just got the latest issue of the Jameco catalog, and they've discontinued (at $5.95 no less), the stock 6502 processor. Is this the beginning of the end of the '02s availability? I know that CMD produces a C02 version (available in 100's quantities), but it's just not the same...

VAX?PDP cab kit bonanza

by cmcmanis＠mcmanis.com

I was at a store today wading through a relatively large box of cab kits to find one for a VCB-03 and the owner made me an offer I couldn't refuse. I bought the whole box. However, not too suprisingly most of them are for DHV-11's (4 RS-232 ports and a ribbon cable). So I've got quite a few and willing to offer them for cost+ shipping. As follows: $6 gets two DHQ11 cab kits (8 ports total, two groups of 4) postage paid anywhere in the continental US. (Priority mail) $15 gets two cab kits *AND* a DHV-11 (8 port Q-bus board, quad wide) anywhere in the US. $15 get you two cab kits *AND* a UNIBUS DHU-11 (hex wide) (limited qty, I've got 3) If you want to add 8 serial ports to your Q-bus based vax or pdp this is a good deal. --Chuck

CBM 8032 and 8035

If somebody in Socal wants the units let me know, \ > > > no way do I ship the monsters. How about the guts? Leave behind the iron frames and the massive transformers but box up the floppy drives and motherboards? I'd consider paying a few bucks over shipping for the active parts. I have several PETs that I'm restoring and I understand not wanting to mess with those heavy, bulky enclosures. I just had a PET 4016 (9" screen) shipped from SoCal. It was $35, but considering it was from the Physics Department at the college in Santa Barbara, it has this neat Lab I/O device plugged into the expansion bus and Katakana charaters on the keyboard next to the graphics symbols. I've never even seen a picture of one like this, but I digress. How much would you want to pull the good stuff out? Most important are the mainboards. Of secondary importance are the keyboards, and of minimal but some remnant of importance are the floppy drives. The entire lot should fit in a xerox paper box (if there's room to pad the 8032 boards. If it's too much hassle, I understand, but I have to ask. I'd rather see something survive than nothing. Of course, if anyone wants to get them, intact, they should receive preference. I'm only trying to save the good bits.

PDP 8/e memory boards

I didn't know a DEC 16k was available for the 8/E, was this third party?. What are the board numbers? I think I have the 8k prints but they weren't where I though they should so will look further this weekend. Digital numbered the MSB (high) 0 always so EMA 0 is the 0/16k field select bit. On the 4k core when the link is in it selects a 0 for that line. Chapter 9 in the 8/E handbook on highgate documents the omnibus signals and section 4 pg 3-60 of the mantenance manual vol I documents the memory. Section 5 pg 3-93/3-96 documents the front panel. Several front panel schematics are also there. David Gesswein http://www.pdp8.net/ -- Old computers with blinkenlights

I'm about to start making them myself - I have enough to interconnect my -8/e CPU but not any of the core. I've been working with a PDP-8/a hex MOS board (16K and 32K), but I'm not sure if the rev of the timing module I have generates the right signals to work with hex memory (there's an issue with CPU boards with three digits in the handle numbers vs. four; I have some of each from two CPUs) I'd love to remove one odd variable from the mix before I start to component-level debug my -8/e CPU boards. At least I have this late-1970s HP logic analyzer... I can attempt to set up stuff so it looks like the pretty pictures in the three-volume maintenance set. I may just order a bunch of connectors from DigiKey and make some new interconnects.

Tandy/Radio Shack TRS-80 Model 4

by John.Honniball＠uwe.ac.uk

Having just reassembled a TRS-80 Model 4, I must have a quick rant about the way this machine is put together. If anything, it'll be a guide to future Model 4 owners (and the Model 3, presumably). I started off with a working machine but no boot disk. The message I got from the corrupt disk supplied was "ERROR". That's it, no more explanation, just one word. I was lucky enough to find a manual and a boot disk in a secondhand bookshop here in Bristol. So, I decided to try the machine again, but I didn't want to trash the new disk in a faulty drive (see, Tony, somebody's listening!). Take care when opening up the Model 4 because the CRT comes off with the lid, making it heavy and off-balance. The back end of the CRT (with the connector on) is very close to the internal metalwork of the chassis, too, so don't lift the lid off backwards. And don't forget to remove the single bolt from the top of the back of the lid. To get the drives out, you have to remove four bolts per drive. Top drive first, fiddle about with the cables, then the lower (drive 0). All seemed to be OK, so I tried to get them back in again. Turns out that you can't get the bolts back in without removing the power supply PCB. So, with the drives back in, I powered it up. No screen display at all, no "ERROR", nothing. Damn. After a while checking IC sockets and tracing video signals, I put the dud disk back in and got "ERROR", nice and clear on the green screen. You don't get any error message at all if there's no disk in the drive. Now I tried the new boot disk, and sure enough, it worked! First task, set the system date. According to the manual, it only accepts dates up to about 1987! Next, copy that good boot disk before I do something daft to it. I used the "backup" command, followed the prompts and... it failed. The new-looking disk actually has some blemishes on the oxide surface where it's been stored for so long. Oh, and if you try to boot a non-bootable disk, you get a nice friendly message about that disk being a data disk -- now why couldn't they make it say something when there's NO disk?? Finally, the serial port, external floppy disk port and expansion connectors are "convieniently located" on the underside of the machine. -- John Honniball Email: John.Honniball(a)uwe.ac.uk University of the West of England

Lynx and Netscape both objected. I use God's browser, Internet Exploder, er, Explorer. Version 5. With Active Desktop. Active Desktop's desktop-as-HTML sucks, but it imbues Windows with so many other useful features, and since Stardock's Object Desktop relies on Active Desktop's presence, why burden my machine with another browser?

Apple Johnathon & Apple Macintosh II: Seperated at birth?

by netsurfer_x1＠hotmail.com

I have read something at applefritter that intrigued me: that Apple was thinking about marketing a system known as the "Johnathon" (Successor the the Mac, perhaps?). The basic design was very similar to that of an Acorn RISC PC: You bought the base "module" (What OS that run? Mac OS?) as it was called, & you could buy additional modules that would allow you to run other operating systems. Unfortunately, Apple canned this computer because they thought that everybody would just buy the MS-DOS module. My question is: Was this the original concept for the Mac II, or is this something completely diffrent. ____________________________________________________________ David Vohs, Digital Archaeologist & Computer Historian.

Sorcerer Emulator goes freaking haywire

by foo＠siconic.com

I don't know if anyone else has experienced the same problem but I had a difficult time getting rid of the Sorcerer emulator (virus). I believe this was the Java emulator. I went to the website over a week ago and checked it out and then never went back again. However, today it popped up on it's own somehow (from one of my browser windows I think). I couldn't get rid of it. It seemed every window I clicked on, the emulator would try to establish a presence in that window. This included other programs, the toolbar, etc. I couldn't kill it from the program manager (CTRL-ALT-DEL) and closing all the browser windows didn't do any good either. I could still move my mouse but at that point nothing was responding. I did another CTRL-ALT-DEL and the window came up but I couldn't click any buttons. Finally I hit CAD a bunch of times in frustration and rebooted my machine. Someone ought to let the guy who wrote it know that he has a serious bug somewhere.

zenith minisport hd problems

by SUPRDAVE＠aol.com

I read some archived messages about this computer and seems to be the power board in the computer itself was/is dodgy so that's most likely the problem and i've not enough experience to diagnose and fix the problem. 8-( looks like this computer will go with the other nonworking machines like my kyotronic85 and ps2 model 90xp.

Ok... I'm interested. In fact, I've been looking for a copy of OS/2 newer than the 1.0 and 1.2 I've got for some time! How much?

Announcing... Rent a wreck

by Anthony.Eros＠compaq.com

This sounds like a great idea. One caution though -- using UPS between the US and Canada may be problematic. I'm in the process of being bitten on the rear end because of this. It appears that UPS in Canada will not ship "personal effects" to the US, nor will they insure them. According to the UPS claims folks in Canada, personal effects includes any item that is not a new commercial good. If it's used (like an old computer) it's "personal effects" and as such any damage or loss claims will be denied. I'm still hoping UPS will find my missing package from Canada (a DEC Computer Lab), but if not, I'm out $700 (yep, I got _really_ carried away on an ePay auction) and will be really bummed. -- Tony > ---------- > From: Mike[SMTP:dogas@leading.net] > Reply To: classiccmp(a)classiccmp.org > Sent: Wednesday, July 26, 2000 10:56 PM > To: classiccmp(a)classiccmp.org > Subject: Re: Announcing...

Slightly OT: OS/2 2.1 for sale/trade/free

by vaxman＠uswest.net

Hi All, Whilst searching my office for another VGA controller I ran across an un-opened (NIB!) OS/2 Professional Developers Kit (beta version) CD. The sticker reads: includes NEW 3/93 OS/2 2.1 Beta If I recall correctly, this CD has everything you need to setup and start developing an OS/2 machine. Since it's so old, you probably will require a fairly generic 386 or 486 machine. Any offers? Reply off list please... clint PS If the demand is high enough, I'm willing to burn copies...

PDP 8/e memory boards

by lemay＠cs.umn.edu

I'm trying to get my 8/E working. I've installed a basic set of boards: M8330 M8310 M8300 (with jumpers to the previous board) M837 memory extension M849 RFI shield <memory> M8320 bus loads Well, first off, the extended address load switch seems to be broken, so I cant access extended memory (maybe I should yank the M837 board for now). I tried a few core memory sets, but I dont think they are working properly, or possibly they arent configured properly. The memory sense/inhibit boards have jumpers for selecting the memory field, I'm guessing you have to start at field 0 and increment in continuous fields? What about 8K boards, do you have an 8K at field 0, and an 8k at field 2, and the boards would be covering fields 0 - 3? Is EMA 0 the high or low bit on the field selector jumpers (on the memory sense/inhibit boards)? Whats kinda confusing me is that I have a pair of 8K core memory sets that came from one computer a LONG time ago, yet they are configured for fields 1 and 2, whereas I think they should be 0 and 2. I also have a 16K core set, does anyone have any information on that board? The highgate docs appear to be for a hex wide 16k board. I think the majority of lights on this computer are burned out, leaving about 8 bulbs working. Is there any way to verify that using front panel controls and no memory? -Lawrence LeMay

An alternative to UPS

by Anthony.Eros＠compaq.com

I just got off the phone with the shipper. No news yet, but he did confirm that once we've given up hope, he'll refund my money. Of course, what I _really_ want is for UPS to find the box. Aside from a picture on Eric's brouhaha web site, this was the first one of the DEC Computer Lab digital logic trainers I'd ever come across. I hate to think that UPS has somehow managed to lose it. -- Tony > ---------- > From: Eros, Anthony > Reply To: classiccmp(a)classiccmp.org > Sent: Thursday, July 27, 2000 5:12 PM > To: classiccmp(a)classiccmp.org > Subject: RE: An alternative to UPS > > When I talked to the shipper, I confirmed that I wanted the package > double-boxed and said I wanted it insured.

Shoddy UPS service
