I have one somewhere. Been a while since I've used it. IIRC, there are a few different modes. One for running programs, one for writing them (in basic), possibly also some more standard calculator modes. I got a sharp portable computer, and liked that a lot better, actually, but my LCD screen cracked :( Basically you find the right mode for what you want to do, and just go. It's a pretty simple machine by common standards.

1771 floppy controller questions

by tothwolf＠concentric.net

I have a complete TRS-80 Model I that has a dead Western Digital FD1771-01 chip in its expansion interface. Does anyone know if a National 1771-B01 is a suitable replacement? What would be a fair/reasonable price for a new 1771 these days? -Toth

OT: Moving, must sell....

by DAW＠yalepress3.unipress.yale.edu

Sorry about the OT, but some of this may be close to 10 years old... Here's the deal. I need to get rid of this stuff, before I move. It's located in New Haven, CT, ZIP 06520-9040. Make an offer. Trade is possible, but only for DEC Alpha, Vax, Sun Sparc, that kind of parts & stuff. If you want the whole pile, I can meet you somewhere, in CT, to hand the stuff to you. Easier than shipping. This will end in one week... Send me an offer, I'll reply to let you know I got it. If there are multiple bids on something, I will do a random draw next Tuesday... Let me know if you have any questions...

Computer Technician's Handbook (1971) and Computer Automation PDC 808 (1968)

by guerney＠bigpond.com

At a charity book sale I turned up this book* which promised to "turn an ordinary electronics technician into a computer maintenance specialist". And what a wide open field it was - as it says in Chapter 1: "as of some recent reckonong, there were in the neighborhood of some 50,000 computers currently in operation in some capacity or other" The book used as an example of a "Typical Small Computer" the Computer Automation PDC 808. The picture of the roughly Altair/Imsai sized box was actually labelled "PDC 808 Controller". The CCC list says this box was released in May 1968 (4K of 8-bit core) and there are just a couple of references to it on the Web I can find, and none from recent years. The book contains over 200 pages covering this device to the minutest detail. It seems a shame that such an apparently rare machine was chosen so we do not have a chance to work through the exercise today - it is rare sin't it? *by Brice Ward, published by Foulsham-Tab Ltd (the English version of the American TAB books) Phil

One of the 3rd party TCP/IP apps was reputed to do this - possibly Multinet.

To be fair it was never touted as an enforcement method. It was only there as a minor hurdle or tripwire to warn you that you were not allowed to run some software or to limit your usage of said software. This meant that you had to take deliberate steps to get past the LMF. Presumably a defence of "I didn't realise" would have been somewhat harder to use in court! Antonio

Well the "new" Encompass site is updated and guess what, no "free DECUS" memberships anymore, now its $79.99 "early bird special" and $99.99 regular membership. No doubt when they become HP it will be even more irrelevant to the cause of preserving old DEC gear. I sure hope they offer lifetime VAX licenses at some point. --Chuck

IBM 5394-01B 3 1/2" diskette controller

by dtwright＠uiuc.edu

There are two of these available near where I work, if anyone is interested. They're about 2/3 the size of an IBM 5150 PC and each has 1 3 1/2" drive in it. They also contain disks labeled "IBM 5394 SYSTEM DISKETTE". If anyone's interested, please contact me off-list. There's no guarantee of availability as these things are not actually in my posession, but I doubt they're going anywhere :) You'd pay shipping & handling but that's it. - Dan Wright (dtwright(a)uiuc.edu) (http://www.uiuc.edu/~dtwright) -] ------------------------------ [-] -------------------------------- [- ``Weave a circle round him thrice, / And close your eyes with holy dread, For he on honeydew hath fed, / and drunk the milk of Paradise.''

Some of the above is more worrying than the rest. It would be interesting, though, to see what would have happened to VAX had it not been discontinued.

by CordaAJ＠nswc.navy.mil

If I remember properly, the licences issued on behalf of the hobbyist VAX/VMS effort were good for 1 year only (from date of issue?) and needed to be re-issued every year (please correct me if I'm wrong... I am not very VMS literate :-) At the time I remember reading of this, someone indicated that it wouldn't be a problem, since all you needed to get a new licence was a current DECUS membership (which was free)... we were told not to worry....

FS: Victor Technologies Computers, Software, Documentation

by victor9000us＠yahoo.com

Please respond directly to victor9000us(a)yahoo.com The Victor 9000 was an impressive early generation 808x based PC designed by Chuck Peddle. With a (for the time) high resolution green screen no glare monitor, large 1.2mb 5 1/4" floppies, and built-in sound capabilities, it was an excellent machine. Indeed, Victor scored many early sales wins with large companies such as Ford Motor Cars. I have a considerable stash of Victor Technologies equipment, software, and documentation that I must part with. Read on... Victor Technologies Vicki Portable System ----------------------------------------- Rare Victor 9000 compatible portable (well, luggable, though smaller and lighter than the original Compaqs) >from the early 1980s. This system has dual 1.2 mb 5 1/4" floppy drives, 640KB of memory, keyboard, built-in small green screen (8" or so I think), and built-in serial and parallel ports. (Floppies are NOT PC/AT compatible, as Victors use a variable speed floppy system to achieve 1.2mb.) System is in full working order (I booted it yesterday to make sure), and comes with MS-DOS 2.11 and MS-DOS 3.1 for Vicki and diagnostics diskettes. Victor 9000 System with PlusPC IBM Compatibility Kit ---------------------------------------------------- When Victor realized that PCs and PC clones were going to become the standard, they created the PlusPC kit to retrofit Victor 9000s to become PC compatible. PlusPC systems can boot in either "V" mode, which is fully Victor compatible or "I" mode which is fully PC compatible (with the exception of not being able to format 360K diskettes). System can read and write both PC 360K diskettes and Victor 640K single side or 1.2mb double side diskettes. This Victor 9000 system has had the PlusPC kit installed. It is a dual double-sided floppy system (the PlusPC was installable only on double sided floppy machines) with 512K of RAM and built in serial and parallel ports. It comes with power cables, MS-DOS for PlusPC, MS-DOS for Victor 9000, monitor, keyboard, and manuals. The system works-- I booted it yesterday. Also included are a set of customer built, foam lined, hard sided carrying cases for the system. I also think I have the original controller board that will let you turn this back into a pure Victor 9000-- if I have it, I'll include it with the system. Victor 9000 Networking Equipment -------------------------------- I have a few (4 I think) Victor 9000 Network cards. I also have the network interface boxes, some cabling, software for DOS 1.25 and 2.11, documentation, and device driver software. The hardware was all taken >from a working network a few years ago, and I believe it all works, but I won't promise. Just about guaranteed to be incompatible with any other network hardware. ;-) Other Victor 9000 Hardware -------------------------- 1 PlusPC Kit, not installed in a system, with manuals still in shrink wrap. 2 or 3 Victor 9000 memory boards from various manufacturers. May not work (I'm sure one doesn't), but also full of memory chips. 1 Victor clock card. May or may not work. Miniscribe III hard disk. May or may not work. Victor 9000 Software and Tool Kits ---------------------------------- MS-DOS 1.25 for Victor 9000 MS-DOS 2.11 for Victor 9000 MS-DOS 3.1 for Victor 9000 CP/M-86 for Victor 9000 Victor Hard Disk Tool Kit Victor Hard Disk Tool Kit II Victor Graphics Tool Kit Victor Graphics Tool Kit II Victor Programmers Tool Kit Victor Audio Tool Kit with audio amplifier card (Allows voice recording. The victors have a built in voice playback capability.) Victor CP/M-80 system with Z-80 card. Yep, you really can run Z-80 programs on a Victor. Assorted Victor diagnostic disks Word Perfect 4.x (DOS version) for Victor 9000 with manuals Complete VictorPULSE public domain software library- over 70 disks of software, information, and documentation for Victor 9000s. Write Crane RAM disk for Victor 9000 White Crane Brooklyn bridge (PC transfer software) for Victor 9000 Fancy Font (scalable fonts from dot matrix printers) for Victor 9000 Victor Documentation -------------------- Victor Hardware Reference Manual Victor Supplementary Hardware Reference Manual (This is also available in electronic form as one of the disks in the public domain software set.) Victor Field Service Bulletins Valid Technologies Memory Board manual & diagnostics Pretty complete set of Channel 9000 (Victor User Group) newsletters Odds and Ends ------------- US Robotics Courier 2400 (external) modem. (Yes, there is communication software in all that software above-- it's in with the public domain stuff. No, it won't do TCP/IP.) US Robotics Sportster 9600 (external) modem Citizen 120D dot-matrix printer Panasonic KXP1092 dot-matrix printer Large supply of blank 5 1/4" disks. TERMS AND CONDITIONS -------------------- Make an offer. I would prefer to send it all out as one huge load or several large ones, but will consider other proposals. All items are available as is, without warranty. I've powered up the systems to make sure they work. Most other stuff should (and did the last time I used it) work unless I've made a note to the contrary. It would be a real pain to try and install and test it all again now, so I'm not. Shipping from southern New Hampshire is *your* responsibility, though I could probably be persuaded to deliver within a reasonable driving distance (an hour or less). :-) There's a lot here.... if someone wants the works (my first choice), it's probably enough for a small pallet load. You got questions? Just ask. Please respond directly to victor9000us(a)yahoo.com-- not to the mailing list. __________________________________________________ Do You Yahoo!? Yahoo!

PDP-8/E questions

The undercoat is the right one. Keep in mind the color is light gray and can look almost white in a gamma saturated picture. Also over the early years DEC standard gray has never been exactly the same color. It tended to standardize over time.

Finally got a Hayes Chronograph!

by erd_6502＠yahoo.com

After much searching (and missing two that went for auction when I was on vacation), a Hayes Chronograph has finally fallen into my waiting hands. Turns out one of the people I was camping with when I was on vacation had one in the basement that he just gave me. He picked it up 7 years ago for $10 at a Hamfest. I had to resolder the AC jack and it now works great! I was contemplating writing a Perl module to front-end it (and hide the AT syntax for setting/reading it). I was curious if anyone had any suggestions about where it belongs on CPAN (since I was planning on giving the code away). I wasn't sure if it belonged in the "Time" branch or if there were a more appropriate branch for device "drivers" in Perl. I was contemplating an approach were you create a Chronograph "object" and have it set the time to either now or a given time and return the time in text or seconds-since-the-epoch format. A Perl module would also give me a place to document the command syntax for the future - currently the only thing I've seen is a single CP/M program in assembler and the scanned docs on a classiccmp member's site (Thanks muchly, Rich!).

OK, so which? White or gray? I'm inclined to believe Allison, as my RX02 is the same colour as my QBus machines, and that's gray. But my 11/40 is lighter than that (though still not white), and in the pictures on David Gesswein's pages (eg http://www.pdp8.net/pdp8em/pics/topboards.shtml?small) it looks decidely white.... Mine has obviously had a thick coat (undercoat?) of grey, same colour as my RX02, 11/23plus, 11/03, 11T23, 11/34, etc; but also had a thinner coat of white on top. -- Pete Peter Turnbull Network Manager University of York

Multibus I items For Sale

by r_beaudry＠hotmail.com

Hello all, I am trimming back my collection of Multibus I items. I am still keeping some card cages, power supplies, prototyping cards, and other cards, but I need to make room for other stuff :-) I would like to get some small amount of $$ per card, plus shipping, so please make offers. I will take offers until Thursday morning, to give the international and digest readers time to make offers. Stuff goes to the highest bidder, and remember, $0.00 is a valid bid. The vast majority of this stuff is untested, and is sold strictly as-is, so keep that in mind when bidding. I'm not looking for eBay prices, but I did pay for a lot of this stuff, so I'd like to get some of it back. Oh, by the way, MAKE ALL OFFERS OFF-LIST!!!!! I will NOT post updates to the list. Offers made to the list will be summarily dropped in the bit-bucket, and the offender will be summarily dropped into the molten iron bucket. Also, please do NOT email me and ask what the current high bid is. Make your bid, and deal with it :-) No documentation is included, unless stated explicitly below. Here's the list: - Qty. 8 Intel PWA-1000359 (seven are further marked "REV 01B"). These are in fair condition, some scratches on the tops of some ICs, and the ceramic caps are scratched. Also, the rotary switches for address decoding have lost a bit of their "snap", and are mushy to turn. - Qty. 7 Micro Industries BLC-508 I/O Expansion board. Seven of these are still in their original box, with waranty card. The eighth is unboxed, but in equally excellent condition. These are very nice boards, and although they all show light markings on the edge connectors, they haven't been used a lot. Rotary switches all snap nicely. - Qty. 1 National Semicondutor BLC-508 I/O Expansion board. Nice condition, very clean. - Qty. 1 Intel Comm. Expansion Board, PWA 1001197-04 L B F. Looks like an SBC-534, but it's not marked "534", so I'm not sure. Board in good condition. - Qty. 1 Ciprico Tapemaster. P/N 81006101A. 2 50-pin connectors for tapes, board in nice clean condition. - Qty. 1 OMEX Interface/Format Memory board. No idea what this is for, but the board is in nice clean condition. - Qty. 1 SMD 2180. Again, no idea what the board is for. 1 60-pin connector, 4 26-pin connectors. Nice clean condition. - Qty. 3 Multibus bus-extender boards. One is by Prototek, one by National Semiconductor, and the third is a no-name brand. - Qty. 1 Intersil MCB 512 memory board. Again, nice and clean. I believe I also have the manual for this. - Qty. 1 Plessey PSM 512 memory board. Nice and clean. I believe I have the manual for this. The Plessey board, or the Intersil board (can't remember) is not fully populated, and does not have sockets for the missing chips (ie, you'd have to solder in sockets, or solder in the chips). Keep that in mind.... Shipping will be by USPS to anywhere in the world they let me ship.... I will quote actual shipping charges when I know who gets what.... Thanks! Rich B.

PDP11 Processor handbook

by rhudson＠cnonline.net

I just picked up a PDP11 processor handbook. Listed on the front also the pdp11/04/24/34a/44/70. There is a picture of two of the shorter white system cabinets, one i guess is one of the front loading tape driver the other case has two "RL02" unit separated by "somthing" perhaps a cpu with no front panel lights. The book is copyrighted 1981. Has this book been scaned? is it already available on the internet? If not, I will make it available to someone who will scan it and return it to me..

Inaccessible CP/M programs in Altair32

by ajp166＠bellatlantic.net

Zcpr (V1) could be run on 8080 (compiled for) with reduced features. The advantage of this was an enhanced CCP,. There were several other enhanced CCP replacements Xccp being one that could also run on 8080. It was the code efficientcy of the z80 over 8080 that essentially killed the 8080 as many apps could use the Z80 instructions to compact code, sometimes significantly. ZCPR relied on this as did The BDOS replacements (P2dos, Suprbdos, NOVAdos, Z80dos). Allison -----Original Message----- From: Jim Battle <frustum(a)pacbell.net> To: classiccmp(a)classiccmp.org <classiccmp(a)classiccmp.org> Date: Monday, November 26, 2001 3:48 AM Subject: Re: Inaccessible CP/M programs in Altair32 True, but Rich's emulator is of an Altair -- one with an 8080 in it. ZCPR2 & 3 were Z80-only affairs, I believe. I recently picked up Richard Conn's ZCPR book for $10, but I haven't yet had time to do more than page through it quickly.

Remington Rand 409

by egendorf＠mit.edu

I am helping to gather original documents and/or artifacts concerning the Remington Rand 409-series computers for the Remington Rand museum being set up in Rowayton, CT. The models of interest are the 409-2 and the 409-2R. These are tube, punch-card, and programming panel machines from the 1950s. We are interested in documenting the location of all surviving artifacts, but also would like to acquire particularly interesting items by donation or purchase. We are looking specifically for anything related to the programming of these machines, such as the programming panels, programming manuals, or the programming jumper wires. Photographs or drawings of programming panels (originals or reproduced in third-party publications), with or without programs wired on them, also would be of interest. If you have any of the above, or have more general items such as Remington Rand brand computer tubes or punch cards, whether or not you wish to sell or donate them, please e-mail me at: egendorf(a)mit.edu. Thanks.

I have one plugged into my Lisa, but here's the deal with the serial port: It seems that the Lisa mouse setup was a little strange. The port was covered by a plastic "hood," which attached to the back of the case by snapping into two little holes. One hole on each side of the port. This covers the metal "ring" that you're looking for. (I assume the Mac mouse is also looking for it ;) If you've got the mouse plugged in, chances are good you'll yank the hood off when you try to unplug the mouse. Otherwise, you will snap the plastic catches on this hood when/if you try to remove it, AFAIK. You should be able to take a flat screwdriver, and put it in-between the plastic hood and the case, and pry out on the plastic. It should pop right out. This will also make it much easier to plug/unplug the mouse. :) Regards, Chris Christopher Smith, Perl Developer Amdocs - Champaign, IL /usr/bin/perl -e ' print((~"\x95\xc4\xe3"^"Just Another Perl Hacker.")."\x08!\n"); '

Inaccessible CP/M programs in Altair32

by ajp166＠bellatlantic.net

CP/M marks a file delete by changing the first byte of the directory record with E5h to replace a value of 00 to less than 040h. It also does so for every file extent for that file in the directory. A completely empty directory by default contained the E5h mark as formatters back tehn used that as the data fill on a freshly formatted disk.

Inaccessible CP/M programs in Altair32

by ajp166＠bellatlantic.net

Correct save for CP/M only used 0-15 for the V2.x and ZCPR extended this to 0-31. The areas were not protected directly from each other but were logically seperate. It made file management easier on a logical volutme without a heirarchial (non flat) directory structure. FYI: the byte used to carry user is the 0th of the 32 bytes in a directory entry. Values (byte) 0E5h, 0FFh, 0FEh are reserved for erased(e5), deleted(Fx). To add to this the high order bits of the file name 8.3 are reserved for control/ Those bits control RO, system(invisible) and other status items. All file names were 7bit ascii. ZCPR and other utility programs extended and used those bits for things like archive status abd public files(accessable from any user #).

Inaccessible CP/M programs in Altair32

by rcini＠optonline.net

Hi: I'm making progress with using CP/M under Altair32, but I have one newbie question since I don't have much experience with CP/M. The disk image I have shows one program in the directory, STAT.COM. Running STAT tells me that there is about 167k free (on a 330k disk). Looking at the disk image file with a hex file editor reveals that there's more programs on the disk. I seem to remember something about password protection on a CP/M disk. How do I get around this so that I can see what else is on this image? Thanks.

SMC HDC9224 datasheet / pinout

by Antonio.Carlini＠riverstonenet.com

> Anyone know where there is a scanned or web version of the SMC HDC9224 > data sheet and pinout? Try a search on http://www.freetradezone.com for something containing hdc9224 and you'll find the datasheet (four times). The App Notes both look useful too. Note - freetradezone is about to stop being free, so don't hang about! Antonio arcarlini(a)iee.org

Hi; I have posted the rest of the cards, that listmembers did not speak for under my eBay user name Innfosale. Most are cheap, starting at $4.00 Here is a URL: http://cgi6.ebay.com/aw-cgi/eBayISAPI.dll?MfcISAPICommand=ViewListedItems& userid=Innfosale&include=0&since=-1&sort=3&rows=50 I will ship internationally. The Global Priority envelope is $10 and will hold a dual width card. Air Mail is a little cheaper for several cards. Paxton Astoria, OR

Is HSC90 a PDP-11 or what?

by gunther＠aurora.regenstrief.org

Who knows what processor/architecture an HSC90 is? Is it a PDP-11? What's it's bus? Sounds like it doesn't mix with UNIBUS or Q-BUS cards at least not looking at the card numbers "Lxxxx" (HSC) vs. "Mxxxx" (UNIBUS/Q-BUS). The reason I'm asking is that I'm looking for the most multi- use of my big-iron hardware that takes up so much space. I believe I will be able to run the console computer of my future 11/78x as a PDP-11. Would be nice if this is possible with the HSC90 as well. I would like to: - provide a PDP-11/RSX-11 environment for my neighbor to play with without getting a dedicated PDP-11. Probably I can do that in the future with the LSI-11 of the VAX 11/78x that hopefully some day will decorate my garage. - try running 2.9 BSD on a PDP-11. Not knowing much about 2.x BSD, I could imagine making the HSC90 into a UNIX-based file server or something. regards, -Gunther -- Gunther Schadow, M.D., Ph.D. gschadow(a)regenstrief.org Medical Information Scientist Regenstrief Institute for Health Care Adjunct Assistant Professor Indiana University School of Medicine tel:1(317)630-7960 http://aurora.regenstrief.org

Want to be the subject of Christine Finn's next book?

by vcf＠vintage.org

Christine Finn, author of _Artifacts: An Archaeologist's Year in Silicon Valley_ (available for sale on Amazon, more information at http://www.artifactsthebook.com/) is starting on a new book that will cover how people use technology in the United States. She would like to profile/interview a collector in every state of the union, including Alaska and Hawaii. Christine says: "I am about to start on a follow up to 'Artifacts: an archaeologists's year in Silicon Valley'. It will also be published by MIT Press, and take a broader look at technology in America. Central to research will be travelling to as many parts of the US as I can - Hawaii and Alaska included - over the next year. However, I do have very limited resources and would be really grateful if any collectors or classic computer enthusiasts could offer me an overnight stay and/or a place for me to get online. More than that, it would give me the chance to meet more of you, and find out about how you feel about technology in its various forms. I can offer a copy of the book and an Artifacts reading/discussion in your locale, if you'd like to arrange it. "If you can help, do please get in touch with me christine.finn(a)arch.ox.ac.uk". If you would like to be considered, please respond directly to Christine at <christine.finn(a)arch.ox.ac.uk>.
