Quoting from the manual: * To copy high capacity, non-copy-protected disks (1.2 or 1.44 MB) you must use the TCM program included on the Deluxe Option Board software disk. * The Deluxe Option Board is not capable of copying copy-protected, high density disks. 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

by CCTalk＠catcorner.org

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? Kelly -----Original Message----- From: Owen Robertson [mailto:univac2@earthlink.net] Sent: Tuesday, May 27, 2003 8:13 PM To: Classic Computer Mailing List Subject: XENIX Distribution Disks 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.

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' :-)... And that libraries only need to keep 10 books ('we already have 10 sets of bound pieces of paper with ink on them').

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?

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.
