by JRichardson＠softwright.co.uk

a couple of questions: does anyone have a spare 16MHz 68k CPU (or a source in the UK who may sell them - Maplins don't). There must be lots somewhere gathering dust since everyone moved to the later 68k family chips (all I have spare are the stock 8MHz versions). Lots of non-home-computer stuff seems to use them (phone exchanges, network equipment, video processing boxes etc.). also, does anyone know of anything that used 68450 chips? (they're 4-channel DMA controllers for the 68k apparently). I found a couple of these amongst the piles of junk I have and am curious as to where I might have got them - I can't think of anything I've ever stripped for parts which may have used them! :-) cheers Jules

New Acquisitions

by jss＠ou.edu

Well, all, I'm happy to report a few additions to my small collection. (1) DEC LA120 (DECwriter III). I bought this on eBay for a steal a few weeks back. It looks to be in decent condition. The shipper packed it very well, but neglected to wrap the LA120 in something before adding the paper-strip packing material. Thus, the thing is filled with paper strips, and I've still not taken the time to disassemble the LA120 to vaccuum/pick them all out. (2) DEC VT102. There was (and maybe still is) a lady selling what is probably a whole room of VT10xs on eBay, at the rate of one unit every week or so. I contacted her directly and asked if she had any units for which I could make a direct offer. She did, and I bought one. It was handled very poorly by UPS, as the top part of the case came off and now won't go completely back on and the case had several pieces chip off. It's not as pretty as it could be, but it *is* functional, so I'm satisfied with the purchase. In other news, I found some LA36 ribbons, LA120 ribbons, a box of teletype paper, 1981 PDP-11/04/24/34a/44/70 processor handbook, and a 1973 PDP-8/e/m/f small computer handbook, all for great prices on eBay. -- Jeffrey S.

Sears SR/2000 (Nakajima AR-30) information ?

by SUPRDAVE＠aol.com

In a message dated 01-04-27 23:26:23 EDT, you write: << My wife wants to sell this printer in a yard sale, but the collector in me is telling me to hide the printer in a safe place. Does anybody have an owners manual for this thing? I'd like to know what the 8 dip switches control. I'm willing to bet that they have the same functions as whatever printer Nakajima licensed the design from (Epson FX?) I know that it emulates an Epson of some sort, because I used it on a PCjr a long time ago. It has a Centronics parallel interface, and some sort of weirdo serial interface (Commodore?). According to Nakajima, it might work using Epson FX or IBM Proprinter III drivers. The printer is interesting to me because I've never seen another one, and Nakajimi is not a household name for printers here in the US. ;-) >> I wouldnt call it collectible, really. I have the SR3000 and it's a epson fx80 compatibile i think. It is good if you have an apple // and run GEOS. There are no drivers for the SR3000 that I had but it did support the SR2000.

Super Star Trek Source

by jim＠calico.litterbox.com

Since it's come up, I've re-added the scans of the Super Star Trek sourcecode in Basic from David Ahl's "More BASIC Computer Games". There's no link from my home page, but the inside link will work. It is: http://www.litterbox.com/jim/trek/ Be advised the scans are quite large - 300dpi - to make OCR work better. -- Jim Strickland jim(a)DIESPAMMERSCUMcalico.litterbox.com ----------------------------------------------------------------------- BeOS Powered! -----------------------------------------------------------------------

Apple //c compatible

by ken.keller＠sk.sympatico.ca

I recently got my hands on a Laser 128 Personal Computer, but no way of finding out if it works, as it's missing a power cable, or possibly an external power supply? It has DC 15V marked on the case over where the power cord is supposed to go, and 7 pins arranged in a circular pattern. I need to find either pinouts, an actual cord, or the external power supply for it. Anyone have an idea as to where I can find any of these? Thanks, Gen

Needed: TRS-80 Model II Keyboard & Boot Disk

Does anyone have a spare TRS-80 Model II keyboard, boot disk, or manuals? I got one of these wonderful systems today, along with the disk expansion cabinet, but no keyboard, disks, or manuals. It seems to work fine, but without a keyboard or software, I can't do much with it. Any help is greatly appreciated!

Shutting down cleanly ... sync; sync; sync;

by mbbrutman＠chartermi.net

I remember hearing what is probably an urban legend about the proper way to shut down a Unix box. The console operator is supposed to enter the sync command three times by hand (and not on one command line like the subject shows it) to ensure that the disk writes got out. Now these were older boxes, and the drives may have been slow, but this surely had to be an exageration. The story has a great punchline though: sync; sync; sync three times if you want to stop me .... Mike

Yes, these machines do have a reputation for being a service nightmare, but assumedly since this is a refurb system it will have been checked out, and Sun would offer some warranty on it as well. It is a PowerPC based system, so you'd end up with even a little more power than the '040 machines that you were searching for.

TRS-80 question

by rdd＠smart.net

Greetings, A while back, I purchased a TRS-80 Model III with 48K of memory, but I can't access the BASIC interpreter... that is, if it has one as I was thinking it did. Do I need to use a boot floppy in order to do anything with this machine? Also, weren't some TRS-80 systems able to use a hard drive? Funny thing, I still have the book that I purchased from Radio Shack about 20 years ago (doesn't seem possible that it's been that long) so that I could use a TRS-80 in a computer lab in college: _BASIC Computer Language: It's easier than you think!_. Five dollars and ninety five cents... wow, try buying a new computer-related book at that price now! -- Copyright (C) 2001 R. D.

The version is David Ahl's book isn't Apple-oriented, though it must be close to the Apple version (which, if I recall correctly, was in Integer BASIC). I do have a copy of that somewhere. However, at the moment my machines are strewn (I think that's about the most descriptive word I could use!) all over the house and workshop as I'm in the final stages of "sorting out the junk". I doubt if the Disk ]['s are even in the same room as the Apple ][ or //e, and i'm sure the floppies aren't. Nevertheless, if you care to remind me in a week or two's time, I should be able to dig it out and kermit a copy across to something net-enabled for you. [5 mins later] Aha, I've found the disks. What you're looking for is called "APPLE-TREK", and it's 53 blocks of INTEGER BASIC. -- Pete Peter Turnbull Network Manager Dept. of Computer Science University of York

A few PDP11 questions and FREE Cipher tape drive

by fernande＠internet1.net

Hello, Before I continue with my Vax 3400, I want to get my PDP11 put together, physically. I have a few things I would like to find, and a few questions. My 11 came with a 3 4-port serial cards. They are M8043 boards. I can't see myself using that many serial ports. Does anybody have the little blank steel plates to put in a BA23 chassis so I can remove the plates that have the 4 db25 connectors? Also, I need the plate that fits into the space below the serial ports. It looks to be slightly larger than a centronics 50 SCSI connector. Would anybody have the dip switch and jumper settings for a M8190-AE, that's a KDJ11-B from a 73 or 83. My 11 was upgraded from a 53. How about memory? If I use the memory that came with it, and do a "map" it tells me the memory is parity. I bought a few surplus boards and one appears to be ECC memory. I don't know anything about ECC, is it better than parity? I have a 2-meg ECC board and 2.5 megs worth of parity memory between 2 boards. One of my parity boards says "Mos RAM" What is that? It is a M8067 LJ. I am thinking that I would like to keep the chassis out of the tower. Does anybody have a spare plastic bezel for a rackmount setup. I don't have a rack, but it would take up less room if I keep the tower in storage. What to call this thing? It has the cpu board from an 11/83, but it doesn't have the PMI memory of an 83. I would like to upgrade the little square badge to reflect its current config. Also, does anybody want a big Cipher tape drive? I also have a Emulex TCO2 (I think that's it) to drive it, although I don't have the cables to hook the two together. It would be free for the taking. I don't think I want to ship it.

TrackStar E usage - Update

by RCini＠congressfinancial.com

Hello, all: I'm muddling through this a bit. I found an old CGA monitor up in the attic that I attached to the TrackStar. I'm able to boot the TS into Integer Basic successfully. I still don't know if the composite output works since I think that there is a problem with the Apple Composite monitor I have (it displays only a yellow background). I think that the updated FAQ mentions that it's a video level problem. Using the TS utilities, I was able to create a DOS3.3 disk image in the TrackStar format. the TS will not "boot" that image, nor will it boot the image included with the drivers. I still can't get it to boot. I just checked the Apple2 FAQ and the TrackStar page was updated about 1 month ago. It mentions that some TS disk images are available from the GSWorldview archive, a link which doesn't work. Does anyone have a link to the working archive? As a result of this experimentation, I think that I'm going to do a TrackStar Web page this weekend. Rich

Although if you stripped either of those > machines for parts, I would feel justified in stripping _you_ for parts :-) hmm, strip away :-) It's possible... I never had a complete XXX system, but Torch used to be my local source of PC bits (around 1990 or so) and I knew the guys there via a friend of mine. I remember piles of XXX machines on the shelves gathering dust, not sure what happened to those (are Torch still around? Unlikely). Occasionally I used to get other odds and ends from there (I have a set of XXX floppies someplace) so may have had a dead XXX system board or something >from them which I pulled the 68450's from. I used to work for a place up in Cambridge that was primarily a PC repair shop, but they used to sell anything computer-related so long as it was mainstream-ish (ie. lots of Amstrads etc. too). Occasionally we'd get oddities in, which is where a couple of my bigger systems have come from. The boss always wanted such machines stripped for useful parts (typically just memory and disks, workstation monitors if they were there) and then the rest was scrapped :-( Unfortunately he always wanted a ridiculous amount of money for any of these systems complete, otherwise I would have saved whatever I could (anything with SCSI disks seemed to automatically command a tenfold price increase!). I have a vague memory of at least one XXX system which passed through there, an IMP system, several big Apricot towers, and some Acorn Unix system of some sort. It's possible I scavenged the 68450's from the bin awaiting disposal, although I have no idea what I thought I was going to do with them :) I seem to remember a big white cabinet on wheels (3' high, 18" wide by maybe 4' deep) which we used to ride around the warehouse on :-) No idea what the innards of it were though! Oh, for some reason video memory was never saved - if we had a dead PC SVGA card it just got thrown out as-is. I had a nice little scam going pulling memory off these dead boards and selling it to people wanting to upgrade their PC video cards from 512KB to 1MB.... the video memory was usually intact even if the boards were toast. cheers Jules

The information I've seen suggests that SGS-Thompson parts were 12MHz and Motorola-badged ones would run at 16 (even if they were badged as 12's).

MicroVAX 3100 booting question...

The OS intercepts the sinal from the switch and does a clean shutdown. (Unlike the Sun Ultras I've used, where the soft power so rarely works when we want it to, that we've often ended up yanking the power cord because nothing happens). > NetBSD and OpenBSD boxes seem to boot fine, albeit slowly.

What do you mean by "proper", anyway? Even a journaling file system like XFS can't preserve data that was being written when it was interrupted, and you WILL get some data corruption, even if it doesn't corrupt the structure of the disk (making a bad block). Just because some systems silently deal with most problems next time they start up doesn't mean you've not done some damage. One day it won't be repairable without intervention. -- Pete Peter Turnbull Network Manager Dept. of Computer Science University of York

Rapport PCjr expansion chassis

by mbbrutman＠chartermi.net

The PCjr in question with the expanded memory is only counting up to 128 when it POSTs, so I am pretty sure that the expanded memory isn't getting any power at all. If the memory would appear during the POST, my life would be wonderful. My other extended PCjrs POST past 128KB. So are there any Rapport Drive II owners out there that want to tell me what the external power supply looks like? Does it output the same as the PCjr power brick, or is it a different beast? The Rapport looks like a pretty neat device. The standard PCjr diskette controller can only support one drive. They use the standard controller, but they "borrow" some of the lines on the floppy cable and run it through some additional logic to add two drive support. It also looks like it has a parallel port and a clock/calendar on it. It's also got a switch labelled "PC/PCjr" - it either disables all of the addon crap, or it adds a feature that I'm unaware of. Any guesses? Mike

Hello, all: Well, I've finally gotten around to playing with the Diamond TrackStar board. Has anyone gotten this to work successfully? I've downloaded all info that I can find relating to the TS, but it only includes the "hardware" portion of the install manual. Does anyone have the "software" portion of the manual? Anyway, here's where I am so far: The board's installed and the software that I have seems to recognize the board and allow me to do certain things, like configuring the drive slots and assigning PC ports to the virtual Apple ports. I was also able to create a 10mb ProDOS volume on the C drive of this test system (a 486/66 with 16mb of RAM). I have a genuine Apple ][ floppy drive connected to the TS. I can "boot" the Apple ][ drive, but it does not seem to recognize the disk. I've tried ProDOS8 and DOS 3.3 disks, neither one of which works. I did have the cable upside down initially, and then reversed it. The drive light comes on at the right time, so I'm hoping that I did not trash the drive. The TS has a composite video output, so I figure that I can connect it to the Apple Color monitor I use for the ][+ I have. All I get is yellow streaks. I don't have a generic 9-pin RGB monitor to try the direct video output. I also noticed that the TS has an empty 16-pin socket at position U63. Since I have an incomplete manual, this may be for Apple Paddles or something else. Any info on this? As always, any information is greatly appreciated.

TRS-80 Mod 12 for sale

by nerdware＠laidbak.com

Hi, gang. A couple of years ago, I dove headlong into the old computer collecting thing, thinking naively that I was doing something unique. I was going to build a great online museum, and have all these neat machines displayed thoughout my house and possibly at the local university. Then I discovered this list, and realized that not only was I not alone in my pursuits, but that I was also small potatoes compared to some of you. Plus, the collection started to take over the basement, as they are wont to do. I also design theatrical sound effects, and I'm trying to build a small project studio here in the basement. That endeavour has taken over most of my free time. So, I started paring down the collection to a few choice pieces plus those with sentimental value to me. I did a entire display at the local library of Tandy equipment last year. I realized, while setting it up and subsequently taking it down, that I should keep the Model 1, the 100 & 200, the Pocket, and the Micro CoCo and jettison the rest of the Tandy collection. Rather than put this sucker on ebay, I thought I'd give first shot to my extended cyberfamily here on the list. I'm going to start with a Model 12, with two 8" floppy drives, keyboard, and two external 20mb hard drives. Don't know how well it works, but I was told that it booted last time it was powered up. I don't have any software other than what's loaded on the hd's. I've realized that I just don't have the time and no longer have the inclination to mess with all of this stuff, so it should go to someone who does. As I said, this is going in the kitty to finance the purchase of a synth or two for the studio, so I would like to get something out of it. This one wasn't a freebie for me. Also, if you know what one is, you know how bulky and heavy they are, so I would like to limit it to pickup in the Northwest Indiana/Chicago area. Valparaiso is about halfway between Chicago and South Bend, Indiana. Actually, I don't care where you live. If you're willing to drive to Valpo, that's fine with me. If you have problems with this email address, as my provider filters based on ORBS and sometimes things get stuck, use my work address pbraun(a)olivellp.com. I'll take the best offer as of Tuesday May 1st at midnight. Depending on how this goes, I have more Tandy pieces that I'll put up here first instead of ebay. I also have a mess of Bytes from the early 80's on that I'll offer as soon as I get 'em sorted, hopefully this weekend. Thanks.

se/30 disk weirdness

by red＠bears.org

I brought home an external FDHD for my SE/30 last night, to facilitate retrocomputing tasks. Plugged it in, switched on the Mac, tested it out, shut the Mac down, and unplugged the disk. Now, when the external drive is unplugged, the system somehow still thinks it's there. I get a disk icon with an "x" in it at boot as it tries to boot from this external drive which is not there and finds (surprise!) no system folder on the disk. The system then goes on to boot more-or-less normally from the internal SCSI disk. Once finder starts loading, I get a dialog box that (depending) says one of two things: "This disk cannot be read by this Macintosh. (Eject) (Initialize)" with the icon indicating the (non-present) external floppy. ~or~ "Initialization faild: disk is locked. (OK)" Dismissing these dialogs result in processing resuming normally for a second or two, and then another identical dialog being thrown up. Repeat ad infinitum, et ad nauseam. The internal disk drive continues to work normally (within the above constraints). As soon as I reconnect the external disk drive, everything is happy again. As soon as I disconnect it... bang. Nose demons. I am utterly baffled. What's wrong? How do I fix it? ok r.

Motorola 68000-16 and 68450 chips...

Ethan Dicks wrote: >Was the MC68000-12 rated to 16Mhz, or did people just run >it that fast? I remember it was an issue for people who >tried to clock-double their A500s. Motorola made a version of their MC68HC000 that ran at 16MHz. Back in the late 80's I was doing processor design for Nortel switching equipment and we had some applications that were written for the 68000 that would have taken too much work to convert software over for the 68020 (a lot of our stuff ran in supervisor mode, not user mode). SGS-Thompson was a licensee for the 68K family, and was the first company that produced a 16 MHz 68000. I think theirs was NMOS, not CMOS (it sure got warm). One day the Motorola guys brought in one of their sales managers to try do drum up business for their 68020 and I showed them the SGS-T part and asked them if they had anything like that. The answer was "we'll get back to you on that", which was then followed up with "you can use our 12 MHz 68HC000, run it at 16 MHz at room temperature for development, and soon we can provide screened parts that will run at 16 MHz". Eventually they did provide MC68HC000-16 parts. Regards, Alex The Calculator Museum Web Page http://www.calcmuseum.com

MicroVAX 3100 booting question...

I wish more machines had this feature. My old DEC 486 laptop did it even better: you hit the switch, it goes off instantly, and when you hit the switch again it came right back up where it was, no rebooting, no scratching on the disk, just instant on.

not a DEC video cable?

by red＠bears.org

Yesterday, I picked up what I thought was a VAXstation colour video cable at a recyclers. I had nefarious reasons for doing so, and ended up being disappointed to find out it didn't work with my VAXstation (3100m76, GPX). What other systems used DA15 (socket) <-> 3 BNC video cables that also featured mid-cable breakout for keyboard/mouse? The give-away should've been that the keyboard connector is not an RJ-style jack. Instead, it has mini-DIN6 (PS/2-style) keyboard and mouse connectors. ok r.

On what a 8050 drive can work on Every PET/CBM except the ones with the original ROMs, and the CBM II series (B128, P500, B600, 700, etc.) The 8050 is a dual 1/2 megabyte (per floppy) drive using quad density (96tpi) single sided disks (not to be confused with high density, I have read double density disks can be used in a pinch), usualy more common to find 8050 software disks used in the CBM business line or the CBM-II (B1-28) line then in the mass consumer PETs. Unfortunaltely it cannot read 1541 or 2040/4040/2031 disks.

DEC RRD40 CDROM Drives

by dittman＠dittman.net

I recently acquired some old DEC equipment that that two RRD40 drives with SCSI adapters. I quickly replaced them with some real SCSI CDROM drives. Now, I enjoy classic equipment and like to see it preserved, but I draw the line on the RRD40 drives. They deserve to die. However, there may be some people that may actually want these oddball drives and SCSI adapters, so if you want them, they are yours. All I ask is that you pay for shipping, and I really only want to ship these in the US. There are no caddies available, and if you aren't familiar with the RRD40 drives they don't use the standard caddies. Also, one of the drives has a CD in it, and when I booted the unit before removing the drives the CD was labeled as an OpenVMS V7.1 doc disk. However, I don't know if that is accurate, since I didn't bother taking a look at the contents. I also don't know if the CD or drive will survive shipping with the CD in place. Also, the SCSI adapters are only for the RRD40 drives and I've removed the three ICs that are useful to me from each board. So, if you want them let me know by Friday, or I'll just trash them, without honor, and without dignity. Can you guess that I've had to install a VMS upgrade with an RRD40 drive and had to swap several CDs to load layered products with only two caddies? I really, really, really don't like RRD40 drives. -- Eric Dittman dittman(a)dittman.net

Repair techniques ... I/O pins and power supplies

by mbbrutman＠chartermi.net

I've always wanted a PCjr with an expansion chassis on it, but they were pretty expensive, and I got by without one. 15 years later I have found one on Ebay and bought it, but alas it's not a happy ending. There are at least two serious problems that I need to fix. The first problem is a broken I/O pin on the expansion bus that comes off the motherboard. The pin is in a 60 pin rectangular connector, and spacing is tight. he broken pin is a data line pin, so if I don't fix it, I can't add any sidecars to the machine. How does one go about replacing a pin? Is it possible? Or am I going to have to desolder the connector and try to replace the entire connector? (And I'm not good with a soldering iron ... I can't even tin wires.) The second problem looks to be a bad power supply. The expansion unit has it's own power supply because the PCjr power supply is only about 33 watts. The expansion unit has extra memory in it that is not being seen by the system unit; I suspect that is because the +5 output on the power supply is reading about 1.8 volts. (According to a digital multimeter.) I measured this with everything connected, so there certainly is enough load. (I don't think that this is even a switching power supply, so the load issue is moot.) The power supply has a "pick" line that is probably activated from the main unit, so that it doesn't have to have an independent power switch. How does such a pick line work? Is there a way to fool it on? What does it use for a ground? (I didn't see one clearly labeled that belonged to the pick line ... perhaps it was the same ground as the +5v line?) How can I confirm that this power supply is truly toast? And it is, then how do I replace it? (I'm willing to scab in a reasonable substitute - it probably can't be a switching supply though because there won't be enough load - it's probably only 512KB of chips on board. The expansion unit is a Rapport if that helps anybody. Thanks, Mike

VAX 6000 3-phase conversion (was: Re: Three Phase)

by gunther＠aurora.regenstrief.org

Robert, you are awesome! I would very much appreciate if you took some pictures. I did some more experiment today and had quite strange results. Now that I understand that the two black and the brown wires are the three phases and the blue is null, I hooked up brown with P1, the two black ones with P2 and blue with null. When I plugged in, I saw the power line controll lights 2 and 3 flash up real quick and then they were out. When I turned on the main power (T-switch) I could measure 110 V at the auxiliary receptacles as it should be. However, I could not find any 220 V at the round plug. I tried two variants: with leaving protective ground open or closing it at N (I know, this was only temporary ...) When I had protective GND on N I would see the PL1 controll light flash tooo. But I never got any 220 V between any of the pins on the round connector. Now this may be because I tried with the power unit from the VAX that has some (unknown) power problems. > The cable that connects the round > connector to the `power & logic box' has only six wires, two from each > phase. There are a number of other connections available on the round > connector, which leads me to believe it's a standard part for anumber of > different power schemes. >From the inside it looks as if each lead goes to at least two of those pins. This would seem reasonable as the pins themselves look pretty small for 800 W full power ... > Here's the fun part! Inside the `power & logic box', all three phases ( > no neutral!) follow a simple path thru a 20A 600V fuse, and then into a > full-wave bridge rectifier, DEC part number 11-26520-01.

It should be 100% reversable. My plan is to buy a receptacle box for the original power plug and wire that box near my extra circuit-breaker box in the laundry / computer room in the basement. Given that the stange behavior of the power control lights are explained and my mistake in measuring the round connector's voltage output is discovered, is there anything to rewire inside the AC power box? I wonder, are we the first ones to fire up their 6000 in their private dwellings? BTW: has anyone noticed major interference with radios or TVs (the label on the machine talks about it ...) regards -Gunther
