Some things seen

by maxeskin＠hotmail.com

It just looked odd. It was like a regular PC case but smaller. It was two shallow plastic tubs. At front, all there was was two 1/2 height 5.25" drives. The whole thing was about as tall as 1 full height. In the back, it had the standard MB connectors (RS-232, Parallel), composite RF, and a 9-pin video (I don't recall what type). It had one horizontal expansion slot with the little cover missing. I peeked inside but couldn't see the ISA connector. >Could you elaborate on "peculiar" (and what is a Heathkit kit XT?).

Ethan, The z80 believe it or not is still in production and has to be one of the most common 8 bitters along with the 6502. It also has one of the bigger resources for tools, code, and knowledge around. < I gave away a couple of 68K S100 boxes to a friend a couple of years ago. < Since then, I've gotten that Z80 Starter Kit with the S100 connectors. Wh < sorts of boards might I be able to find for which there is Z80 code? Coul Unlike PCs the z80 world doesn't really revolve so closely around boards or one vendors word of how the OS is implemented. So... it sorta makes the question open ended. < I find/build a floppy controller and get some sort of CP/M BIOS ROM and < turn it into a CP/M machine? I guess I'd need a serial port for a console Getting a bios rom would be near impossible, as most cpm systems did not do rom bios like PCs do! The bios was loaded at boot time. the loader was a minimal chunk of code (as small or smller than 128 bytes) that loaded the bios which then loaded the rest of the OS. That made the bios very changable as the users discression. Writing your own bios and putting it an eprom(or EEprom) is very doable. The book you need (or the chapter in) is the CP/M alteration guide. that can be found at the site listed. Finding more boards (assuming S100) is also not that hard. there are people here that can help right here on classiccmp. One development platform is to get MYZ80(it's on the web at the SIMTEL site) a z80 and CP/M emulator that runs on 386 or higher dos(or win 3.x, maybe w95) platforms. With that on your PC you can surf the web for tools and apps needed to run languages, assemblers, debuggers and what have you to develop code. < at least a 5.25" controller, and BIOS source (with a cross assembler). Any disk size/format you may want is doable from old single density 8" to IDE or SCSI. You might find hardware for any or all, but 5.25/8" was common. FYI: if your writing the code, most 8" double density controllers with 765 or the more commonly used in that time frame WD179x can also do 3.5" formats. < Anything else? Is 32K reasonable for CP/M, or should I go for 48K? The For CP/M 32 is the minimum to do useful work even though you can run the assembler and debuggers in 20k. A good system is 48 or better 56k with some setup to switch out the eprom to get access to all 64k. < only copy I happen to have, BTW, is an original CP/M distribution disk < for the Commodore 128. Will that be adequate, or should I dig for somethi < more generic? The C128 is furthest from generic IMHO, but if you have a c128 it's a good place to start as a development platform. FYI with notable exceptions CPM (primary componenets are CCP, BDOS and BIOS) is generic for all 8080/8085 and z80 system and only the bios code is different as that's where all the IO work is done for terminals and disks. There is a CP/M website on the net where you can get binaries or even sources as well as manuals. I'd look here if I were you: Visit the "Unofficial" CP/M Web site. MAIN SITE AT : http://cdl.uta.edu/cpm MIRROR AT : http://www.mathcs.emory.edu/~cfs/cpm Applications, look at the FTP site at OAKLAND.EDU and SIMTEL, I'd guess there are 20-30,000 programs out there and most with sources. Good luck, Allison

VM/SP

by Philip.Belben＠powertech.co.uk

> The question is, what was VM/SP? I know it was IBMs, and it ran on large > mainframes. Where can I find information about it? The only info I can find is in a couple of glossy brochures from IBM. One is about the 9370, the other about the 3090 series. Respectively, IBM Virtual Machine/System Product (VM/SP) This is a multi-user, multi-processing operating system for interactive processing. It provides productivity tools for commercial and engineering/scientific environments, decision support and program development. With its connectivity enhancements, this system is particularly suited for remote sites that have little or no programming staff. and Simple end-user interaction with VM The VM/XA Systems Facility and the VM/SP High Performance Option both provide a virtual machine environment. Together with the Conversational Monitor System (CMS), they permit each end-user to access the IBM 3090 system independently, with the perception that he or she is the sole user. Communicating with the IBM 3090 via VM/CMS, Vector Vacility users can develop, test and execute vectorised applications online, using a comprehensive range of IBM Assembler and FORTRAN compilers, libraries and productivity tools. VM also provides guest System Control Program (SCP) support, not only for other IBM SCPs but also for IX/370, IBM's implementation of UNIX. Sorry I can't be of further help. Philip.

PDP-11 info needed.

by cfandt＠servtech.com

Last night I poked a little around the RA60 and the 11/34A that I want to keep. I saw a cable ass'y attached to the RA60 which had two black cables (about 7/8"wide x 3/8" thick) and relatively small plastic 8-pin connector recepticles within a comparatively hefty backshell. Inside the 11/34A cabinet there were a group of four of the same small mating connectors which had four flat, red cables running from that group into a Unibus board in the the BA11 (forgot module number). A 12-foot long cable with two 8-pin plastic connectors each within a large backshell was laying inside the 11/34A box. I extrapulate from a couple of other private msgs that this is probably the UDA50 interface. True? Please tell me about this disk I/F. Any FAQ on it somewhere? Also, I would like to find the same tech info or descriptions on the MSCP interface which I understand the RL01s and RL02s have. Can anyone give me any info on the TS03 tape unit? It is the only one I can keep so I plan to lash it up to the 11/34A or maybe the 11/730 if I indeed keep that (or both by swapping cables?) Looks like a J-11 chip on the CPU board in an 11/23 chassis that was buried in the pile (darn little thing was so small compared to the 5000+ pounds of other boxen that I forgot to mention it in my first msg.) That's basically an 11/73 isn't it? More questions to come.....

New Acquisitions, H8 Question

by cgregory＠lrbcg.com

>1 - Heathkit H?? (like the Z89) No doubt an H88. Generally there will be a Heathkit sticker on the back with the model number. The Heathkit 88 and Zenith 89 are virtually the same machine with differing name plates. >there are two cards marked H8-4 >and H8-5. The H8-4 is a multi I/O card, and I have no idea what the H8-5 >is yet except that it has what appear to be audio cables coming from the >card. The H8-5 is a serial I/O and cassette interface card. I have the complete documentation including the assembly instructions. From the Introduction: "Your Heathkit Model H8-5 Serial I/O and Cassette Interface Card provides you with two input/output ports to the Heath H8 Computer. One port provides a cassette tape interface while the other port provides a serial I/O port.... The Cassette tape interface, along with the H8 front panel monitor, provides you with a fully automated Load and Dunp facility. This greatly increases the system's usefulness by enabling you to store programs and data for later use. The interface will automatically compensate for variations in tape speed and will accept a wide range of input levels. Both high and low level outputs are provided to match any tape unit you wish to use.... The serial I/O port normally operates with the system console. It provides serial communications at speeds from 110 to 9600 Baud at either 20 mA or RS-232 compatible levels...." >1 - Heathkit Dual Floppy >1 - Heathkit H-8 w/ H17 dual Floppy Drive I you ever wish to part with either, let me know.

Intel bubble memory modules

by ddameron＠earthlink.net

Hi all, I went to a surplus store today and they had, I think, 2 Intel bubble memory modules, about 4 x 4 cm x 1cm thick. Would anyone like me to look at or buy them? They also had a Commodore 64, beige with dark keys, modified with 2 BNC jacks on the back. I could find no documentation that went with it. Their price was $10 USD. -Dave

I will let you know if I find any more. I plan to go back to look more anyway, there also appeared to be a cabinet with a 8 inch floppy drive in it (horizontal). I couldn't really get at it to examine it closely. (There was a bunch of bad UPS's around and on top of it). -Dave

That's weird! Yep, darned annoying if you like the graphics symbols. The 4000/8000 series also extended the line height by a pixel or two (thanks to the new VDC) which left a gap between lines, can be gotten around by printing CHR$(142) -uppercase, no gaps- and then poking 59468,14 -set back to lower case-. It was a routine in the screen printing code doing it. I think three or four graphics symbols were readily unavailable, (you would have had to print them out with CHR$()s and then build your program lines around them) two of which I really liked to use, that PET (at school) did't get used much by me...

They do indeed. I have a set somewhere. I was given them by another PET owner who had bought them but never used them, being afraid he'd damage the machine by so doing. I don't recall anything in the PET circuit diagrams etc that suggested you could damage the PET with these, but then again... Philip.

Kaypro10 manuals needed

by bsittler＠nmt.edu

First, get a book on CP/M (the operating system used by the Kaypro 10.) If you need more detailed technical information or have trouble finding a CP/M reference, send me e-mail. Essentially, the Kaypro10 is a 4MHz Z-80 based CP/M machine with a 400Kb floppy and a hard disk (I think.) It was often used for word processing, usually with MicroPro's WordStar. It has a *slow* modem, a serial port, and a parallel port. I'm working on compiling some information on the Kaypro so it can be emulated; once I do this, emulators may serve as "active documentation" for this fine but somewhat obsolete line of computers.

What I do remember is that their services were incredibly lame in terms of user interface, speed, national network, etc. compared to Compuserve.

Looking for VAX FAQs

by cfandt＠servtech.com

Hi folks, Still busy rummaging through the truckload of PDPs and VAXen and peripherals and manuals, etc. I'm looking for any info sources to learn more about a VAX 11/730. FAQs are what I need. Web searches using Metacrawler and DejaNews yield rather meager results. Sites like the excellent PDP site: ftp://sunsite.unc.edu/pub/academic/computer-science/history/pdp-11/ are what I really would like to find. I know I have probably found a good home for the 11/750 but I am considering keeping the 730. First I need to do a heap of studying to check the completeness of the box and to more fully understand what peripherals and accessories I that should keep (which are already setting in the garage) or to search for. Could any of you folks help point me in the proper directions? Thanks for all your help and support so far. --Chris -- -- Christian Fandt, Electronic/Electrical Historian Jamestown, NY USA Member of Antique Wireless Association URL: http://www.ggw.org/freenet/a/awa/

Amiga Software.

by maxeskin＠hotmail.com

Workbench is the Amiga Graphical Operating System, the synonym of Windows on a PC or Finder on a Mac. Kickstart is a low-level piece of software, that could be on ROM or floppy. I'm sure you can guess what Amiga BasiC is. I don't know about TV/Text. Were there any books? BTW, don't put them on the web, the copyrights still hold. I mean, go ahead if you want to, but Amiga has not made the stuff PD and doesn't intend to (Workbench is still in development and 5.0 is coming up) > I ran across a box of 300 disks that were used on a classroom of Amigas >(for an art school.) there's alot of unlabeled stuff, but also cryptic >things like "TV/Text" etc. also, 4 disks that are as follows: > >Amiga Workbench v1.2 >Amiga Kickstart v1.1 >Amiga Extras / Amiga BasiC v1.2 >Amiga Kickstart v1.2 > >can someone give me an idea as to what these are? especially the TV/text >program. if anyone is interested, i could create disk images of these and >dump them someplace on the web. > >-Eric > > ______________________________________________________ Get Your Private, Free Email at http://www.hotmail.com

VM/SP

by DSEAGRAV＠toad.xkl.com

This started as a joke, but turned into something interesting. Someone posted on alt.os.multics about setting a UNIX to pop up the VM/SP logo from /etc/issue. I did one better and crocked up a way to make UNIX actually act like VM/SP at the logon (Mutilated copy of telnetd and a new login program). The question is, what was VM/SP? I know it was IBMs, and it ran on large mainframes. Where can I find information about it? Oh, if you want to see the results of my screwing around (And my first hackery in C that ever worked!) telnet at ubani.umtec.com. -------

PET 2001

by Philip.Belben＠powertech.co.uk

Right. Lets hope my mail software (Lotus Cack-Mail) doesn't crash just as I get near the end of this reply, as it did last time. First, all concerned should glance at Larry A's PET faq, the address of which he posted a few messages ago. Pete Turnbull wrote: > On Jul 7, 6:29, Doug Spence wrote: >> On Mon, 6 Jul 1998, Olminkhof wrote: >> > 8" screen >> >> Or is it 9"?

Blue trim, blue-white phosphor, mangled and rebadged cassette (I can't remember whose) that you open by lifting the lid. Then: 2001-4 and 2001-8 get Black trim and C2N cassette deck Then: Green screen. Next was the ROM upgrade. Usual models were 2001-8N, 2001-16N, 2001-32N, 2001-8B, 2001-16B and 2001-32B. These had full-sized keyboards and external C2N decks. In the UK, 2001-8N with tiny keyboard and built in C2N was common. This was not a new motherboard in an old case - the case was a different shape (slightly less tall). Larry has suggested that these might be the 2001-8K, K standing for Calculator (-style keyboard) (sic). All of these had small screens. >> PET 2001B-8 8kB, Business Style, no Graphics on Keys, 12" screen >> PET 2001B-16 16kB, Business Style, no Graphics on Keys, 12" screen >> PET 2001B-32 32kB, Business Style, no Graphics on Keys, 12" screen >> PET 2001N-8 8kB, Home Computer, Graphics on Keys, 12" screen, Num.

Same as 2001N, just rebadged I've never heard of 2001NT. AFAIK, N = Non business keyboard. The top row of keys was !"#$%^&'() like the tiny keyboard machines - numbers were only on the number pad. B = Business keyboard. Top row of keys was 1234567890, shift gave you !"# etc. This meant you couldn't get some of the "graphics" characters that came from shift-! etc. Hence the reference to "Num.

Was it? That's weird! Even weirder, though, was the lower case implementation. Take a couple of steps back and get a wider view: PET had two internal character codes. Screen codes and "ASCII". Screen codes went from 0 to 127, and didn't include control codes; they then went from 128 to 255 in "reverse field" (inverse video). Bit 6 (the 64s bit) told you whether it was a shifted character or not. 0 to 31 were @, ABC...Z, [\], up arrow, left arrow. 32 to 63 were conventional ASCII. 64 to 127 were the graphics characters you got from shifting these. First problem - nowhere for lower case. PET, in translating ASCII (or PETSCII as it became known) into screen codes, didn't bother to implement lower case. First it checked for control codes (0 to 31 and 128 to 159) and then it ANDed the ASCII code with 63 and stuck it on the screen. Well, sort of. The ASCII codes for the shifted characters were displaced from the unshifted ones by 128 instead of 64. Now, lower case mode. Early PETs kept the bottom 128 ASCII codes exactly as they were. Lower case went in the top 128 - NOT where you'd conventionally put it (those who followed the algorithm above will have worked out that the conventional ASCII codes for lower case would display space, !"#$ etc.). Since lower case was implemented in the character generator only - an I/O pin went to an address line on the character ROM - you had to use SHIFT to get LOWER case. And that was the second problem. Later PETS swapped lower and upper case letters. So now ASCII codes 65 and up, which still mapped onto screen codes 1 and up, gave LOWER case letters, but you pressed SHIFT for upper case. However the OS and BASIC (one and the same, really) treated unshifted as letters, and shifted as meaningless graphics characters, whichever mode you were in. Confused? It is, isn't it! >> Note that at least the early PET 2001 machines came with a white display. >> I think some of the 'newer' ones came with green phosphor instead.(?) > > My 2001-8K is white phosphor.

POKE 59468, 12 (UC/graphics) and POKE 59486,14 (LC) are INDEPENDENT of ROM version. On 8032/8096, 8296 and Fat 40 you can use PRINT CHR$(14) and PRINT CHR$(142) (CTRL-N and CTRL-SHIFT-N except that PET never had a control key) to change between the modes. These codes also change to wide line spacing in LC mode, which the pokes don't. Hope this clears up some misconceptions. Philip.

VM/SP

I'll have a look thro' my IBM junk at home this evening, but I don't think I've got much on it. IBM draw boundaries in different places, but under VM operating system (CP, Control Program) usually ran CMS Conversational Monitor System - a bit like a shell, hence my pun above... The first scripting language for VM/CMS was CMS EXEC. I never used it but I understand it was awful. Later came EXEC2 - lots of & characters (I think - or were they % characters?) to identify names, or reserved words, or something. This was still the official scripting language when I encountered VM, but I, like everyone else, used REXX. This has exhausted my memory - I'm off home. Philip.

I don't see why it would be >impossible to make an SDI controller that used some other command set. Sorry, I was talking at a different abstract level.. just like the RQZX1 talks MSCP on the host side, and SCSI on the disk side, the UDA50 talks MSCP on the host side... I've never worried about what it actually talks on the disk side... >IMHO the RL11 is dumber than the RK11. For one thing the RK11 supports >spiral reads/writes. And to move heads you load the disk address register >with the cylinder you want to go to, not the number of cylinders you want >to move. With the RL11 you've got to remember where you are. Not just that, but the driver is responsible for trying offsets from the center track in case a read fails... Back when we first added support for the RL01/02 to RT-11, it was explained to us that with the RL11, some of the smarts are moved out to each disk unit. This way the controller doesn't have to have all the smarts... supposedly more cost-effective (?!) Anyway, if you lose track of where you are, you have to reset to track zero and re-seek. There are several offsets (positive and negative) that the driver is supposed to try when it fails to read (and maybe write) a block. As already mentioned, the driver has to take care of track to track changes... which means that the driver has to take a user request and process it as multiple single-track operations until complete... Where the RK driver was simple, the RL driver was a PITA... and the convolutions in the MSCP handler are even more impressive...

ISC Intecolor 8051 Circa 1978

by Marty＠itgonline.com

I recently rescued an Intelligent Systems Corp. model 8051 Intecolor terminal/pc, s/n 5013 from the side of a road (there were several printers which first caught my eye, this unit has a wood grained plastic cover which first made me think it was an old window air conditioner as it was face down and covered with other junk). I saw this advertised in the February and December issues of Byte Magazine as a model 8001. The December 76 Byte ad states this is an intelligent terminal that can be upgraded to a personal computer by adding Basic and extra ram (this appears to have been upgraded). I had never seen one of these in person before and didn't realize how massive they are: 17" high by 19 1/2 " wide by 22" deep, weighing at least 50 pounds (although I haven't weighed it). The tube is a 19" color. There are 9 slots inside with a CPU/I/O/Keyboard board (Intel 8080A), memory, additional memory board, prom board (with Basic and others) plus a floppy controller. Ports (DB25) are J1 Modem, J2 Floppy Tape, J3 Keyboard, J4 24 Bit I/O (this port is blank actually),J5 Floppy Disk, J6 USART (port is blank). Unfortunately there was no keyboard or documentation and outside of the Byte ads I don't know anything about this. Does anyone know where I can get a keyboard and documentation for this? Also the power cable is non-standard, per a friend of mine it was used by typewriter manufacturers and is known as a AC Victor cable. Thanks, Marty

That's correct. Now, the interesting thing is that according to pinout charts, the keyboard cables are the same (clock, data, not used, ground, +5). However, the keyboards are not compatible.

Amiga 2000

by jfoust＠threedee.com

I intended a very gentle guiding message for Max, and in no way said anything about censorship except self-restraint in the form of editing recommendations (endlessly requoted messages with one-liner replies drive me up a wall). I gave general advice to search the net before posting, as opposed to treating the mailing list as a magic oracle that answers all your questions. Save the list for the truly obscure questions, not the stuff that's on hundreds of web pages. - John

I don't think Jim's list is quite correct. For a start, there were lots of 2001 PETs with 9" screen and the graphics keyboard, without the cassette-beside-the-keyboard. I've got one here. And the /B and /N series were called 3000's not 2001 everywhere except the USA. The 12" versions didn't appear in the UK until later. According to my (USA) manual, the 2001/B (aka 3000 here) was a 9" screen too. IIRC, the 4000 was the first with a 12" screen, at least in the UK (USA might easily be different, of course), and that's borne out by my manuals. The 12" screen version was eventually called the 8000 series here, and had different firmware (and up to 96K RAM I think, bank-switched). One of the differences between the business and home versions (apart from graphics symbols on the keytops) was whether the machine powered up in upper- or lower-case. > Note that at least the early PET 2001 machines came with a white display. > I think some of the 'newer' ones came with green phosphor instead.(?)

Well, they do, sort-of, but a bug in the IEEE routines prevents it from working with anything other than a printer.

Maybe I used the wrong words - poor english language skill - Of course a regular Serial I/O chip is still needed, the 8089 has no serial (or what ever) I/O of its own. But instead of the main CPU, the 8089 will respond to all requests for data transfer - shure, you could use two DMA chanals for input/output data, but in difference to an ordinary DMA the 8089 could also handle the status lines and drive a non hardware protocoll - from xon/xoff up to HDLC. Same for any other kind of I/O hardware, not only serial, since the logic is software not hardware. Gruss H. -- Ich denke, also bin ich, also gut HRK

Amiga 2000

I just pulled an Amiga 2000 (I don't think it's >10 yet) from the trash. It didn't come with anything else, just the system unit. I looked it up, and I pretty much came up with the specifications. COuld someone tell me a little more about it? What kind of video can I use with this? All it has is a composite RF jack. Also, are the keyboard and mouse PC-compatible? ______________________________________________________ Get Your Private, Free Email at http://www.hotmail.com

Stuff for trade in UK

by mark_k＠iname.com

Hi, I have some junk which I would like to trade for other junk... - Two Wangtek tape streamers. One is 5125EN, the other 5099EN24. These are not- quite-SCSI devices; they require the correct PC interface cards -- PC-36 for the 5099EN24, and probably the 5125EN too. I don't have the interface card. I believe they work; before I figured out that they are not SCSI, connecting them to a SCSI controller allowed me to rewind tapes, at least - Commodore PET 8050 disk drive, in bits. I took this apart years ago to clean, and forgot how to put it back together again. Never had the right cable to test it out anyway. Could be useful for spares if you already have one of these drives. I would like to get hold of a Wangtek 5150ES or 5525ES tape streamer. Or make a suggestion. I live in Wiltshire, England. Bye, -- Mark

I've got a dozen-plus antique rolls that I got from someone on the Greenkeys RTTY mailing list, if you just need a pair. If you search the net for "paper tape", you'll find several suppliers to the computer-controlled machining market, with options for paper tape, mylar tape, oiled, etc. I've said it before, the Greenkeys list needs to meet the classic-comp list.

Tandy 25-1011 Plus Memeory Card for T1000 FS

by rhblake＠bbtel.com

I have a Tandy Memory Plus Expansion Board, tandy catalog number 25-1011 that brings the base memory of the machine from 128k up to 640k RAM. It came from a Tandy 1000 (no suffix) but will work on a Tandy 1000A and 1000HD. Full information documents are contained on line at http://support.tandy.com/support_accessories/2460.htm Not sure if your model works with it? Check the docs for your model 1000 at http://support.tandy.com/support_computer/2512.htm and look under the memory upgrades page to see if it will. I know for sure it will NOT work on the EX and HX models. The card is populated with the full 512k RAM to bring your 128K basic machine up to full DOS RAM. I need $15 for the card which includes shipping to you in the 48 lower US states. AK and HI should inquire to see if any additional shipping applies, probably won't.

Hey, English blokes...what's an Apricot?

by franke＠sbs.de

> There's a mainboard flat in the bottom of the case. It contains an 8086, > between 128K and 960K of RAM (there are 2 versions of the board...), > optional 8087 copro, and an 8089 I/O processor One of the vew designs, that (tried) to uitlize the fill power of the 86-family. In faxt: today everybody is moaning about the 'crude' x86 structure (but using it) and nobody temembers that the CPU was only one single part of the design. A design ready to build high efficient and fast computers for multi programming operating systems (Unix et. al.) > (very fancy DMA chip). Thats like naming the Newton a fancy post it thing. The 8089 was a full featured CPU, just with an special command set suited for I/O operations. Anything from serial I/O via disk I/O up to code translations could done in a very smooth and genuine way. Just imagine that the HW depending part of any device driver would run on a seperate CPU - including all the time consuming puffer/unpuffer, notifications, polling and what-ever operations. The 86, 87 and 89 are three independend microprocessors suited for special tasks (asymetric multiprocessing). Today the x87 is reduced to an additional fp register set, the 89 is forgoten and everybody aplaudes the symetric processing hype :( Just think what kind of computing could be possible if this sceme had worked out - need more float ? just add some FPUs! need a lot of I/O ? add anoter IOC... Need huge 3D power? Add some 'MMX' processors and not just some new commands for the same old FPU. Think I should stop.

Old story, But never true. Everything about copying was done on the Apple ][ years before the C-64 (remember Locksmith or Nibbler ? :). And everything is still the same - easyer than ever (Buy a CD-Burner at USD 100 and get an idot proof copy programm for free) - so the home software market is dead ? Come on, be serious - it's still the same - if one wants a software and it is availabe (in difference to the early Apple ][ age when a pirate copy often whas the only trace about the existance of a special soft) one still buys it, if the price is right - but if the shop asks USD 500 just for a pop up util, one might look around for a copy - everybody wants new soft NOW - and don't want do search weeks just for a pirate. I still belive that most copys are no harm to the manufacturer. Example - I spend something like USD 150 per month on games (just one or two new games - they are horrible expensive in Germany). Same with two friens of mine - some- times we but a game 3 times - one each, since noone wants to wait one day for the copy. Gruss H. -- Ich denke, also bin ich, also gut HRK

ZDS planar type memory board FS/Trade

by rhblake＠bbtel.com

I have a memory board for a planar type ZDS machine, came out of a Z248. This one is the newer type that has four SIMM sockets on it, uses 30 pin SIMMS. There is no memory installed, just the card itself, works great. Goes into the special 32 bit type slots like the CPU, IO and other type memory cards do on planar units. Not sure how many types of ZDS units this will work in. Need $15 for it which includes shipping in the 48 conus states. Will consider trades of equal value cards for ISA, VLB, PCI or even MCA slots, but please no network cards. Will also trade for one or two Microsoft InPort mice, without the cards since I have them. -------------------------------------------------------------------- Russ Blakeman RB Custom Services / Rt. 1 Box 62E / Harned, KY USA 40144 Phone: (502) 756-1749 Data/Fax:(502) 756-6991 Email: rhblake(a)bbtel.com or rhblake(a)bigfoot.com Website: http://members.tripod.com/~RHBLAKE/ ICQ UIN #1714857 AOL Instant Messenger "RHBLAKEMAN" * Parts/Service/Upgrades and more for MOST Computers* --------------------------------------------------------------------

DECmate III

Infos Draco - what is this?

by ekman＠lysator.liu.se

Hi! I chanced upon a strange thing in a thrift shop today. A hand-held terminal of some sort called Infos Draco. It was rather expensive (SEK 250) so I never considered buying it, but I wonder what it is. The case is mainly blue with some yellow and red details. Keyboard is in ABCDE (rather than QWERTY) fashion. The longest side is approximately 10" and it is shaped like an L turned up-side-down with a 40x8 character LCD screen on top. There are no manuals but the box seems to indicate Italian origin. It seems to run on batteries but can be plugged into the wall as well (standard Swedish 220V plug). There is also a phone connection and what appears to be a parallel port. I tried to start the thing, but only succeeded in a red light coming on and a happy beep when I pushed the ON button. What is it? What can it be used for? Does anyone want me to buy it for you? /F

Apple & Commodore questions

by rcini＠email.msn.com

Hello, all: I'd like to do some assembly language programming on my Apple //+. What program was generally used to do AL programming? Did you typically use the built-in Monitor, or was there an "Apple Assembler" program? Also, can someone point me in the direction of a listing/description of the Apple //gs Toolbox commands. I'm picking up an original Mac Portable this week on my way to get more PDP11 stuff at Temple University (in Philly). The Portable is missing a hard drive. Which drive goes into this unit? I seem to remember a 40mb unit. Second, has anyone heard of a Commodore C64k?? I found a news post where a guy had two of these available, but I don't recognize the "k" suffix. Thanks!

All I can say is that it doesn't hurt to tell everyone you meet that you're interested in old, junky computers, the kind that you're about to throw out, the ones that can't run Windows. :-) Tell everyone in the store. Tell them three times, three different ways. Leave your card. Leave an extra six cards. Write "Likes Old Computer Junk" on the front of each. This will at least improve your odds of avoiding this depression in the future. In their defense, they exist to attempt to sell the stuff they get. If it's not selling, what else are they supposed to do? If you want to be sad, ask to see what they cull at the start of the pipeline, when they perform triage as items are donated. I get similarly upset at the triage performed at the my favorite local junk spot, the University of Wisconsin -- Madison Surplus sale, as judged by what I find in the dumpster, and the condition and organization of what I see in the sale area. The almighty PC reigns, but are stripped and separated into bins: keyboards here, monitors there, cases here, spare cards here, manuals over there. I've found two of my Teraks in this shape: main unit separated from extra disk drive separated from monitor and keyboard, and any ancillary docs are long-gone. In the dumpster goes anything not easily identifiable as PC or office equipment, but they're quite lax about that, too - I've seen laser printers and faxes only a few years old tossed, along with desks and chairs that aren't stylish enough to sell quickly.

Old Catalogs & Equip.

by Ferock＠aol.com

I am interested in old (1980-1987) computer catalogs. I'm especially interested in BlackBox catalogs. I also am interested in acquiring old (1980-1987) computer connectors. Specifically, connectors that have their own housing and are used to connect two external devices. These connectors have circuity that converts the data, e.g. serial to parallel conversion or changing signal voltage. The VicModem is an early example of such a device. Any information would be greatly appreciated. Glenn Ferock(a)aol.com

Video game crash

by dcoward＠pressstart.com

Tom Owad said: >What ever happened to The Source? When did they shut down and why? I don't really know. >Video game crash of '83? Would you please explain? I sure you can find a better explaination in any of a half dozen books that are out about the video game business but here is my condensed version for what it's worth: Prior to 1983 Atari was making ALOT OF MONEY selling 2600 units and cartridges (remember PAC-MAN fever). It was the Microsoft of the 70s and early 80s. Many other companies, not wanting to miss the boat, saw this happening and jumped in with their their own systems. Some of these companies were betting the farm on this craze. And it seem like everyone and their kid sister was coming out with cartridges for these systems. (At one point you could send in to the makers of Gravy Train (or was it Chuck Wagon) dog food to get a cartridge called "Chase the Chuck Wagon") I have heard that black market copies of the programming manual for the 2600 cost $10,000, which is a small price to pay if you could possibly make millions making and selling cartridges. Some programmers made 1 million dollar bonuses on a single game and that was back when one programmer by himself would write a game in 6 months. It was a time of madness. BUT, 1982 was one of those years when computers just exploded. Machines like the C64. Easy to set up, cheap, better graphics and sound. People started putting their Atari 2600s in the closet and going out and buying computers. Parents were complaining that kids were playing video games too much. The fad was over. Almost overnight 2600 cartridges when from $20-$30 to $3-$5 each. Atari was the head domino and when they fell, they all started to fall. Some very large companies almost went lights out when the prices fell. Atari was split up into Atari Games(coin-op) and Atari Corp.(home computers) Other companies just faded away. Home video game systems did not come back into fashion until 1986 with Nintendo.

I don't know >>> if they'll actually let me do this repair anyway. >> You counted 120 cycles per second with a _stopwatch_? > Yes, I wondered about that. 120 per minute is understandable, but 120Hz? > No way. Shure - take a 60 (or 50) Hz clock feed the signal and stop the time neded to show a minute (or 10 minutes to get fractions) - or take any other steping device and look at the stepping speed - This way you could even use an old Apple DISK ][ as a counting device - put it on track 30, hook up the signal and wait until it reaches track zero - you'll get an acustic feedback - now its just finger calculations.

Apple & Commodore questions

by maxeskin＠hotmail.com

The Mac Portable uses a special kind of hard drive. A normal SCSI won't work, and I don't think a powerbook hard drive will either. There is a company that sells Mac Portable upgrades, but their prices are ridiculous. Everything is in the triple digits. I'm not sure if they had any original parts. Their hard drive solution was an adapter board for more common drives. You should be able to find it via newsgroups or something. As for the C64, they may have confused it with a 'c', which is the later beige model. > I'm picking up an original Mac Portable this week on my way to get more >PDP11 stuff at Temple University (in Philly).
