As these disks become more prevalent in the market, we may include this capability. -- end quote -- I'm thinking what this means is that you can use TCM to copy 1.44MB 3.5" media, but there's no guarantee that it will reliably copy media that are copy-protected. -Frank McConnell

DOS/Windows for Wang Professional Computer (not a PC clone)?

by drido＠optushome.com.au

Recently I picked up a Wang Professional Computer. Can't find a model number on it anywhere. It 8086 based, 256KB RAM, 360KB FDD, 10MB HDD. It runs MS-DOS 2.11, but it is not PC compatible. A long time before I got this machine I found some software for it. A box of original disks all marked "Wang Professional Computer". It includes 2 versions of the integrated word processor, MS Chart, DOS3.2 and Windows 1.03. Both versions of the word processor run, ms chart bombs saying I have the wrong graphics card. Neither DOS 3.2 nor Windows 1.03 will install. DOS 3.2 just hangs the machine, Windows 1.03 bombs with an interrupt error. The disks seem to read okay. Anyone know what I'm doing wrong or have working copies? I vaugely remember seeing pictures of this machine in the Windows launch issue of Byte. Though it would be cool to have windows running on something other than a PC clone. I think I've even got a copy Balance of Power for Win 1.x around here somewhere.

Mac Net dummy Q's

by cb＠mythtech.net

> Desktop > +- Apple > +- Control Panel > +- Sharing Setup > ('Start' was selected, reboot) No need to reboot after starting File Sharing, and in fact, rebooting can cause the file sharing to be turned back off. So first step, go back into the Sharing Setup control panel, and make sure the Start button says "Stop" (if it says "Start" then click it again, and wait for file sharing to startup, the button will change to Stop when it is up and running) >Now, where is the remote drive >supposed to show up on the local system? In the remote computer's Chooser, under AppleShare. If you don't see the server there, make sure both computers' AppleTalk control panel is set to use the Printer Port, and that AppleTalk is turned on (and make sure the serial TeleNet connectors are plugged into the Printer port and not the Modem port). Also, on the TeleNet connectors, make sure there is a terminator in the unused phone jack on each. I don't remember if the ones I gave you have termination switches on the side, if they do, just make sure it is set to ON (if it is, then you don't need a terminator in the 2nd jack... I know either they have they switches or I gave you terminators... I don't think I would have been brain dead enough to give you them without a way to terminate them) -chris <http://www.mythtech.net>

Cassette Media revisited

by cb＠mythtech.net

Well... audio tapes don't work as a substitute for a D/CAS cassette. At least not with my TEAC drive. First attempt, drive takes the tape, but starts blinking the access light as soon as the drive is locked, never tries to do anything with it, software says "No Media". After a quick 2nd look at the transport, I see a small finger sensor looking for that notch. 30 seconds later with my pocket knife, my audio tape has the notch. 2nd attempt, drive sees the tape, software reports "Busy" as the drive spins the tape to the end, clacks to the end and tries to spin some more, then gives up, rewinds a bit and stops. Software reports "Hardware Error". My guess is, it is looking for some kind of end of tape marker. I tried both clear leader and leaderless tape, neither worked. I also tried a higher grade tape (Type II, 630 oersteds or whatever that word is). I don't know if the end of tape is a specific magnetic marker like a format, or what. Winding the tape to the end in a tape deck and putting back in the drive causes it to rewind the whole tape until it clacks at the end again. So it is definitly trying to rewind to the start of the tape and is simply never seeing that it is at the end. It is possible that the drive is broken, but since it is seen by Retrospect on the Mac, and gives status updates as it goes, and the transport does its thing... I tend to think the drive is fine and I just can't use an audio tape. So... does anyone know a supplier of these tapes? I haven't been able to turn up anyone that actually sells them anymore. A few people on this list offered to try to locate a spare tape for me for testing... but I'm not going to ask anyone to go thru that effort if I can't get a regular supply of tapes anyway. The drive is a TEAC MT-2ST/N50. The following appear to be compatible tapes: MaynStream 20; Teac CT500 D/CAS; Verbatim ST500; Teac CT-600H; Verbatim ST600; Maxell CS-600HD; MaynStream 60; Teac CT-600N; Maxell CS-600XD; Verbatim ST600XD; MaynStream 150. All in all, it probably isn't worth much more effort. Its only a 150 MB drive anyway. So for normal use, there isn't much I can do with it (at least not when I deal with the cost ratio of Zip disks or CD-R's). -chris <http://www.mythtech.net>

The final 'Garage' sale...

by jimw＠agora.rdrop.com

28 May, 2003 ...and then one day you wake up, and things are just not the same anymore... And so it is with the 'Computer Garage'... As of today, I am with great regret announcing the dissolution of the major part of the Computer Garage collection of classic computers and related materials. First; I will detail the method in which this will be done, and then I will detail the reasons and events that have lead up to this decision. -------------------------------------------------------------------------------- The dissollution and redistribution: With the exception of between six and ten units that have particular 'history' with me, all items in the collection will be disbursed. These items will be specified shortly. Beginning in a few days, and proceeding over the next few months as needed a 'catalog' page will be created on the 'Computer Garage' site. For each item there will be a description, a thumbnail picture when practical, an estimated shipping weight, and a date.

XENIX Distribution Disks

I have the 3.1 or 3.2 system, scriptsit, dev system, mbasic, and filePro or Profile16. How urgent are your needs? I only have them available on 5.25" disks (follow the directions on Frank Durda's site to connect up a 5.25" drive). I can probably get to copying them in mid to late June. Just remind me in a few weeks. Anyone else collect the 6000's?

Unfortunately, when it gets here, I will have nothing to use it for, as I accidentally wiped XENIX completely off my 6000's internal hard disk while trying to format a secondary *external* hard disk. I will never again assume that a program named 'hdinit' will actually ask me *which* disk to erase, nor that it will ask for *ANY* kind of confirmation before wiping the internal hard disk... So I am now in the market for some Tandy XENIX distribution disks for version 3.whatever. I don't know the exact version number of the OS that was for the 6000 specifically. Also, should anyone have the Multiuser BASIC disks, or Profile for XENIX disks, those were lost as well... I didn't have any of the original disks for anything dealing with the 6000. I'd also like to get my hands on something my system never had, whose absence was very noticeable - the XENIX Development System, which contains things like the C compiler, mail, and many other things I don't consider optional in a UNIX-based system.

IMC Portcom II

by fmc＠reanimators.org

Submitted for your amusement, something picked up today while out scrounging (really looking for non-classic bits). It's a luggable. Poking out the front: 5" CRT two half-height 5.25" floppy drives (inserted floppies have extra write protect notches cut for use as flippies) 40/80 switch modular jack (6-conductor) brightness and horizontal hold knobs Poking out the back: GAME (DE9P) RS-232C (DB25S) PRINTER ("Centronics" connector) VIDEO (RCA socket) label, handwritten s/n 1193 and checkmarks for 110V 60Hz The detached keyboard has a modular jack too. It's also bit-paired (shift-2 is '"'), in fact it mostly follows the Apple ][ layout (and has <- and -> keys), and it has what look like BASIC keywords on the fronts of many of the keys, including HTAB, VTAB, GR, HGR, and TEXT. No cable between keyboard and luggable. I'm thinking it's an Apple ][ clone of some sort. It doesn't quite power up: no video display on the internal monitor. Pulling the top cover shows the guts. The top floppy drive is a Teac FD55A. The motherboard has five slots that look like Apple ][ slots; the silkscreen on the motherboard labels them S0 S3 S4 S5 S7. Date codes on the visible ICs are 81xx and 84xx so I'm guessing 1984 at the earliest. Someone's been in here before. The 40/80 switch has a lead to a paper clip that ties it (mechanically at least) to an insulated red lead that goes from the motherboard to the display board; this red lead would appear to be the +ve supply for the display. There's also a loose metal cover over the display section; it looks like it may have been held together or insulated by tape or sticky cardboard at some time but this has been removed somewhat. Powering up with the top off makes a red LED on the motherboard light up solid, but the CRT filament doesn't glow. Anyone ever seen one of these before? -Frank McConnell

PDP-11/34A / BA11-K PSU

by jkunz＠unixag-kl.fh-kl.de

Hi. I got some more parts of that disassembled PDP-11/34A yesterday. I think I have now all PSU parts: - power inlet unit with mains cable, circuit breaker ... and a PCB that looks like a small PSU. - one big transformer - one small transformer - one H785 battery backup regulator module - one H745 -15 PSU module - two H7441 +5V PSU modules - a PCB that is labled "BATTERY CHARGER" - a bag full of screws Some time ago I got the front half of the BA11-K, i.e. a card cage with the system units, all UniBus cards, power distribution panel and front panel. Obviously missing: - back of the BA11-K where the PSU bricks, transformers, ... are mounted - fans - bulkheads for the console serial line, the serial multiplexer, RK07, ... - UniBus extender and terminator. [1] I got the card cage, power distribution panel, system units and all UniBus cards in one piece, but disassembled it to clean it. I know how to remount that, but I have no clue how all the PSU parts fit togeter and if there are some parts missing I didn't list above. It would be nice if someone who knows this machine could give me some hints... I was toled that one of the PSU bricks is broken. I found some manuals on http://www.mainecoon.com/classiccmp/PDP-11-34A/ but I can't read those TIFFs. I tried with xv, gimp, tiff2ps, Netscape 4.7x, Mozilla 1.2. I took the CDR with the TIFFs with me to work and tried to view them on a WinXP machine (puke). The machine nearly crashed when I tried to open the files. My SGI Indogo2 is broken so I can not try some IRIX tools. Where else can I get some schematics of the PSU bricks in a readable form? [1] There is an other, smaler BA11 with a custom UniBus interface from Linotype for some photo typesetting machinery... I have the M9312 bootstrap terminator for the "beginning" of the bus where the CPU resides. -- tsch??, Jochen, who is now heating the soldering iron for the Indogo2...

Categorization and description was RE: Collection policy was Re: No space for vinatge computers in

by CyndeM＠vulcan.com

I'm finding many aspects of this discussion very compelling. It got me to wonder some things. How would you categorize and describe classic computer items? Is there an accepted descriptive benchmark in the collectors discipline? Or better still, how would you *like* to see it done? What would be an appropriate descriptive level of a flip chip, a unibus terminator, a cable, a power cable, a backplane, a cabinet part? If you had a museum or archival collection of these DEC things, what would you want to know about them that would make them useful to you?

This is simply rediculous. A PDP9 is a PDP9 no matter what cabinet it's installed in, of even if it's jsut loose backplanes and PSUs... Mind you, I once saw a list of valves (vacuum tubes) that one museum was offering to another. The list had a column of 'condition'. No, it didn't give the emission and gm figures. It didn't even say if the heater was continous, and the getter silver (not white, which would indicate air had leaked into the valve). No, it described how clean the glass was... > I recently recoverd an entire PDP-9 OS thought long lost from three > DECtapes found in a batch of over 100.

The obvious extension of this is that art galleries should throw out all but 10 of their paintains on the ground that they 'already have 10 pieces of canvas with paint on them' :-)...

Checked voltage regulator pins on CPU card, 12 volts on the lower regulator, nil on the upper :-(. It should be interesting to watch the 8800 on ebay, it's got 4 days left. For almost two days (long enough to get my hopes up...:-(. ) I was the high bidder but now it's up to $1000. I wonder how sick this one will get? Ahh well, someday I will own an 8800!

Hi, I recently picked up a model 4 ver 1 with a problem. The system originally worked and booted, after moving the system it started to display random characters on power up and failed to boot.. I removed socketed ICs and cleaned the connectors. The system now displays a blank screen on power up ( although the drives spin, and it could be booting ). If I disconnect the FD controller from the main board, the system jumps into basic ( with video ) and seems to operate. Print fre(0) returns somthing over 48K with the fd disconnected. Any hints?

> To reduce the time involved in making copies, would you be willing to make > disk images, and put them somewhere accessible? That way those of us with > an 8" hooked to a PC could make 8" disks. OK. I've got an ftp server lined up, can even put them on CD's and duplicate a batch on scrap discs (don't ask, I was trying to calibrate a termal CD printer). The big question: What is the best tool to create the disk images? Rawread/rawwrite? dd? cpio? something else? The easiest thing for me is either dd under linux or raw read under MSDOS (like the linux boot discs). I have lots of 5.25" disc drives laying around. All I have to do is hook one up. I'd rather not create the 8" discs myself. The media on them seems to peel off onto the head if you have cheap ones. Then I have to take the drive apart, clean the head... since I've already copied most down to 5.25 (I still have to do mbasic, multiplan, and Profile 16+), I will make images >from the 5.25" discs as time permits and put them up on a public ftp server for a while.

No, that's backwards. In the case of DEC RX01 or RX02 with a DEC controller, the controller card (in the QBus or Unibus) is fairly dumb, it's just an interface. The "smart" stuff is in the drive enclosure. The controller passes a FORMAT command to the drive, the drive chunters away and executs it, and reports back to the controller when it's done. In the case of third-party controllers with "industry standard" drives, the controller is "smart" and the drive is dumb. The controller does the formatting, and sends control signals and a data/clock bitstream to the drive, so you can't do anything > The same situation occurred with the DEC RX50 floppy media. > The DEC RX50 drive could NOT perform an LLF. It works differently than an RX01/RX02. In fact it works exactly like the third-party RX01/RX02 case above, except that DEC saw fit not to include formatting routines in the RQDX1/RQDX2 controller. The RX50 drive is an oddly-engineered variant of an industry-standard 5.25" dual floppy, with almost exactly the same control/data signals. > However, by the time that DEC allowed the RX33 on the RQDX3, > DEC had switched to industry standard HD PC 1.2 MByte floppy > drives and media with 2400 blocks. Yes, the RQDX3 includes firmware that can do the formatting.

I seem to remember that the answer is NO! Correct. The answer is "no", for exactly the reason Jochen describes, and indeed John's webpage says so. -- Pete Peter Turnbull Network Manager University of York

This should tell you most of what you need to know... I did my password hacking on a 5362, but there should be analagous tools on the 5364 PC console. http://groups.google.com/groups?selm=6m4rat85bf4hi45udaj05u5j6pm48e887g%404… Good luck!

TRS80 mod 4 ver1 video/memory problems

by dwightk.elvey＠amd.com

Hi Jim There is a chance that the first crash also damaged the system info on your boot disk. Have you tried using another disk? You could also try putting the disk controller in but put tape over the select line( not sure what is involved here without a schematic ) and tie this line ( lines? ) so that the drive doesn't access. The idea is to see if something in the controller is loading the bus. If this is the case, BASIC won't boot. You could then isolate a pin at a time until you found the failure. Small pieces of tape work well for isolating edge connectors. That is about as far as I'm willing to make any guesses.

Thinline Floppy Problem

by univac2＠earthlink.net

What does it mean when the light on a thinline floppy in a Tandy 6000 repeatedly blinks to the pattern: <long blink>...<blink><blink><blink> When I put a disk in, the drive makes healthy noises, but the light just keeps blinking like stated above, and the system seems unable to detect that there's a disk in the drive. -- Owen Robertson

Hi As was mentioned, not all controllers do single density. MFM double density is no problem. There are a number of programs out there that handle differing sector counts and sector sizes.

If your disk are single density and you have a controller that handles single density then you are OK. Intel's double density was M2FM and not MFM, for the 8 inch disk.

More Stuff for Auction at SYI

by marvin＠rain.org

I have listed some more stuff for auction over at http://www.sellyouritem.com. I have found quite a few DEC flip-chip and other boards that are being listed there in addition to other stuff of interest to listserver members. The area of main interest for list members is in the Classic Computer section at: http://www.sellyouritem.com/ListAuctions.html?CategoryID=1497 The things I am listing there are for 3 day auctions, and that should give everyone here a chance at them before they head over to (explatives deleted) Ebay. If you think the pricing is wrong, let me know as this was my best guess at reasonable pricing for list members. Again, the main idea behind putting them on SYI is to allow listmembers an equal chance at anything they might be interested in. I'm trying to list about 10 items/day there. Stuff that I will also be listing include a PDP-3L, Microvax, some DEC Disk Drive cartridges R????, and some other DEC cards that I have not identified yet. I *think* there are also several 11/34 cards that I have not listed yet, hopefully later today. ------------------------------------------- ebaY's Security Breach and Coverup http://www.auctionguild.com/generic110.html

This demo ALWAYS gets good reviews.... Exactly what I did with my 8-year-old niece at Christmas. She's really into "sums" and arithmetic at the moment, so when I wanted to play with my 8/E, I taught her a little about binary, showed her how to read octal off the switches and lights, and we added some numbers.

Thanks for the tip on the D Bit FDADAP. I will probably get one as I think it meets my criteria. I am not particular interested in reading DEC RX01 & 02s.

Computer-tourism in Manhattan

by norm-classiccmp＠docnorm.com

Hi, folks. I'm starting a vacation this Saturday with a few days in Manhattan. Are there good classic computing or telecommunications museums, or other interesting sites, there? I know IBM used to have a museum in Manhattan, but I never got to see it -- I'd hate to miss something else just before it closed. Any help is appreciated, and I'll gladly take pictures and/or send postcards for those who are interested :-) Norm

DecServer 700 - WWENG2.SYS image

by alexandre.dulaunoy＠ael.be

Dear All, We have received a lot of old DecServer 700 but we are looking for the WWENG2.SYS image ;-) We have looked around the old digital ftp server, but there is only the pr0801eng.sys (not really useful). Where can we get the WWENG2.SYS image for the DecServer ? What is the software licensing for this image ? Is it linked to hardware or was it a separate product from Digital ?

Interdata Model 74

by toby＠russellsharpe.co.uk

Hi, I recently picked up a PDP11/34 for restoration from a surplus dealer and spotted at the same time an Interdata Model 74 gathering dust. Needless to say, I managed to get this as part of the deal.. I'd like to try to restore this back to working condition, but my various searches for information on early Interdata models seems to have born little fruit. Does anyone have any information, documentation, engineering diagrams for this machine? Thanks, Toby

AV11--Need advice.

by sherrill＠frontiercomputer.com

I ran across your 11/4/02 post about leaking capacitors. We have two (so far) PCs afflicted. What scares the crap out of me is that we have a number of them at customers as voicemail servers. You said you replaced with AV22 and AV18, and we'd like to find out if that'll work for us. I also read at overclockers how to replace capacitors. I believe both the PCs are 700 mhz Celeron running Windows XP. I'd appreciate any advice you can give us. Sherrill Lowrey sherrill(a)frontiercomputer.com

XENIX Distribution Disks

by univac2＠earthlink.net

Well, I found someone with a Tandy 6000 keyboard to sell and it should be on it's way to me tomorrow. Unfortunately, when it gets here, I will have nothing to use it for, as I accidentally wiped XENIX completely off my 6000's internal hard disk while trying to format a secondary *external* hard disk. I will never again assume that a program named 'hdinit' will actually ask me *which* disk to erase, nor that it will ask for *ANY* kind of confirmation before wiping the internal hard disk... So I am now in the market for some Tandy XENIX distribution disks for version 3.whatever. I don't know the exact version number of the OS that was for the 6000 specifically. Also, should anyone have the Multiuser BASIC disks, or Profile for XENIX disks, those were lost as well... I didn't have any of the original disks for anything dealing with the 6000. I'd also like to get my hands on something my system never had, whose absence was very noticeable - the XENIX Development System, which contains things like the C compiler, mail, and many other things I don't consider optional in a UNIX-based system. Any help is greatly appreciated... -- Owen Robertson

The Great Auction (Leaving the Hobby)

by cb＠mythtech.net

>How do you have a url if it isn't listed yet? I've >never heard of a delayed listing. When selling stuff on ebay, you have the option of setting your start date/time to something other than right now. It costs more to do this, but it is an option. So like Jeffrey's post said, the auction starts at 6pm PDT Wednesday. So I would assume the link will become valid as of that time (it would be nice if ebay gave you a slightly better message than just Invalid Item so you know you are looking at a not yet valid item as opposed to a totally incorrect listing ID) -chris <http://www.mythtech.net>

DEC Modules F/A at SYI

by marvin＠rain.org

I've just listed some M series modules and a Quad Extender Board over at Sellyouritem.com. The URL for the classic computer stuff is at: http://www.sellyouritem.com/ListAuctions.html?CategoryID=1497 These are set for a three day auction to give listmembers a chance at them. I plan on listing about a dozen+ items a day, so it might be worthwhile to check over there occassionally. We've had some discussion about First Come/First Serve, and that basically means whoever lives at their computer has the best shot at anything offered to the list. I think this might be a fairer way of doing things without giving the whole world a chance at stuff. SYI has *NO* listing fees, and FVFs are slightly less than on Ebay. My feeling is that a three day auction gives everyone on the list a chance to look at the stuff, and bid if they are interested. ------------------------------------------- ebaY's Security Breach and Coverup http://www.auctionguild.com/generic110.html

The Great Auction (Leaving the Hobby)

by jss＠subatomix.com

As promised, the bulk of my collection will be up for bidding in less than 24 hours. For an interesting twist, I have decided to sell my collection in one large lot instead of several medium-sized lots. This will hopefully maximize both convenience and entertainment. Remember, I'm also accepting items in lieu of cash. The auction kicks off today (Wednesday) at 6PM PDT (1AM GMT). I wish all contestants a safe, enjoyable bidding experience. http://cgi.ebay.com/ws/eBayISAPI.dll?ViewItem&item=2732905006 -- Jeffrey Sharp

IBM 8560

by cb＠mythtech.net

Any value to an IBM 8560? Or more correctly, is it something that someone on the list might be interested in. Its a full height tower 286 IBM ps/2 machine. There is at least one hard drive in it, and I think I have a 2nd for it (not sure the sizes, 20 or 40 MB I think). Last I knew it booted and worked fine. I've had it kicking around for some time, and its taking up space. I think it weighs about 40 lbs, so figure on 50 lbs packed for an estimate, shipped from 07450... anyone want it? -chris <http://www.mythtech.net>

LA 120

by marks＠techprecision.com.au

Hi there I saw your post as a result of my search criteria in google, i am chasing any and all documentation on DEC LA 120 and any other relevant PDP material. I have just secured a position with a company that supports this type of hardware, and am having difficulty wrapping my mind around the sheer immensity of the equipment. So any help would be very much appreciated, as i search and search for any documentation. :) Best regards Mark Setter
