I have a problem with an Atari 1030 modem. While I can receive everything correct on the Atari modem I am not able to receive anything transmitted from it to another computer correctly. All I get from the Atari modem is binary garbage. Can anyone help me? BTW dose anyone have any spare Atari cables remember they have 13 pins. On another note I've noticed that flea markets are a pretty good place to find classic computers.

Cleaning up classic books

by dastar＠wco.com

Many of the old computer books I get from thrift stores have the price of the book written in grease pencil on the inside cover of the book. I'd like to remove this safely. Can someone point me to the right place to find this sort of information? Thanks.

More: Irreverence to irrelevance

by dcoward＠pressstart.com

I have to admit that I'm flame virgin, but it looks like fun so I'll give it a shot. I can't believe so many on the ClassicCmp List don't subscribe to the digest! That was the first thing I did.(Change over to the digest) I can't be sorting through 40-50 messages to find the work related one that need to be answered right away. And frankly, collecting computers is a hobby for me, one of many, and this is not the only digest I subscribe to.(Even though it's the one that takes most of my mail reading time.) Yesterday's digest came in SIX parts. In the last year thats nearly the record. Page after page of the same e-mail quoted again and agin. BUT I'm not complaining, instead I suggest that MAYBE the ClassicCmp List should default to digest when subscribing. I think that a digest allows people the time to think out their responses. Many of you are the CP/M-List, this is a good example. You may have to wait 24 hours for a response, but usually it a very thoughtful one. And I think its because (as I remember) CP/M-L defaulted to digest and it just become a slower paced discussion. Also with a digest there is no reason to quote someone in entirety (You just read the other message). You do have to cut and paste, so you're more selective. It true than I'm sometimes 24 hours late on a computer for sale. But then again everybody want to auction off their computers anymore. Well that my humble opinion. ========================================= Doug Coward dcoward(a)pressstart.com Senior Software Engineer Press Start Inc.

It was a pretty cool :little unit. ditto the sinclair microdrives, which were about the size of an old 50p piece (oh, erm... about one and a half times a quarter?) and stored 100k in a ql. they were 2 track, 1/16" tapes - does anyone know the magnetic format in which they stored data? was one track datat and one track clock, or...? they were *sooo* cute :> it's just a shame they were also rather unreliable. most qls have disk drives and ours is soon to acquire one. -- Communa (together) we remember... we'll see you falling you know soft spoken changes nothing to sing within her...

Northstar got its start, I think in late 1976, with one of the first affordable and reliable floppy disk systems for S-100s. It used the then brand new 5.25" floppy disk Shugart had just started making, matched to an S-100 controller board. Up to that time all the floppy systems were based on 8" floppies, which went for, oh, around $1000-$1500 for a drive (and weren't very reliable either). The NS drive was very cheap in comparison, I think around $500, but bets of all you just put it in the box and it worked, very rare for S-100 machines in that timeframe. The drive was single density, single sided, hard sectored with 10 sectors of 256 bytes each, total around 90KB. Paltry compared to the 243KB on an 8" drive, but infinitely better than a Tarbell cassette interface. The drive came with a crude operating system (CP/M didn't work right away because of hardware problems with the boot ROM on the NS controller) and Basic. Eventually Lifeboat got a version of CP/M working with the drive. After the floppy subsystem, NS came out with a unique S-100 floating point coprocessor board. This was actually a sort of bit slice state machine that did BCD arithmetic. A very clever design but somewhat difficult to use. It was fast for it's time. The only software that used it (to my knowledge) was the NS basic and I think one of the CBASIC or PASCAL compilers (Sorcim?). NS made enough from their floppy systems that they started making whole machines, the Horizon and later the Advantage. As with all the S-100 companies, PC's killed them off. Jack Peacock

More List Operation Stuff

by bcw＠u.washington.edu

Well, pretty soon you're all going to get sick of hearing from me, so this will be the last listop stuff I post for a couple days. I read back through a couple weeks of archive and I'm still letting thst digest. For the time being, I've decided not to make any decisions ;) It seems a little common sense and courtesy would go a long way in bringing this list back on track. I'm not so sure that hard-core officiating would make any difference. It would probably just spawn arguments defending the honor and freedom of listmembers (heads up aspiring list operators - that's a lesson I learned the hard way). Even when I was actively moderating this list, all I looked at was whether or not subjects were about classic computers or not. If it goes a little off track, all right. If that continues for too long, a polite message to the parties involved usually retires the thread to private mail. If you think about what you're going to post to the list for a minute or two, you'll know whether or not it will be well received. Spend that time. This list is for recreation. You should be on it because you think classic computers are fun. All of you are people with a common recreational interest - there's no reason to get nasty with each other. If you don't like certain people or topics, just delete them and focus on what you like. If you can't find anything you like, maybe this is not the list for you. I'm getting off my soapbox now. Thanks to all who have sent me their input. Keep it coming. I will lecture you more next week ;) -------------------------------------------------------- Bill Whitson bcw(a)u.washington.edu Network Administrator (425) 352-5209 University of Washington - Bothell Help Desk: 2-5275

VAXStation Terminal Help Needed

by aaron＠lafleur.wfi-inc.com

Hi, Can one of the vaxheads help me with this one.... I have a 3100 who's monitor just died and I want to use a terminal emulator for it until I replace the monitor (should be here in a few days). I know that I have to change one of the dip switches inside but which??? And what's the pinout of the serial printer port (that *is* also the terminal output, right?) ??? I'd kill to get my hands on some original documentation/manuals for either my 3100's or 3200. BTW, the 3100 in question is a 38. Thanks, Aaron

I'm surprised that it took so little time for this list to get to this point. Another list I'm on took about two years for it to reach critical mass before it exploded into three additional mailing lists, all covering the same topic (with the result of many hurt feelings, a list that only lasted about six months before it imploded, with the original list still going strong). As I said to Sam in some private mail I sent to him: I'm not sure what can be done, but if the topic of a mailing list is held too tightly, eventually it'll die (like one of the mailing list I host now, although there are some other reasons for that as well) as there is little or nothing new being added. ... I don't want to seem overly pessimistic, and yes, perhaps the topics have drifted off a bit too much, but actions like yours (and I'm not trying to blame or pin anything on you, this is just my observations from about 5 years of being on several mailing lists (almost all of them high volume)) tend to do more harm over time than good, by splitting the community up, causing confusion, ill feelings and political overtones. And yet it continues (and Sam, in your reply to the above you appear sane and rational, yet your diatribes on the list show a completely different side, and one that isn't very flattering). Bill may "own" the current list, but that still doesn't prevent anyone >from starting up a new list dedicated to the same topic, only time and resources. And perhaps against my better judgment, I'm doing such a thing (Lord help me), and so let it be. If Sam feels that he can run a list better than Bill, or even I, then he is certainly free to start his own and see who signs up. Much like I am doing now. It's there. If no one subscribes and this list continues to flurish, so be it. If, on the other hand, my list takes off and this one dies, so be it. Currently, the only person subscribed is me. I'm not going to add people, it's up to you. To subscribe, send a message to classiccomp-request(a)lists.armigeron.com with a subject line of 'subscribe' (you might want to put this on the first line of the body as well). That's it. You'll then recieve a welcome message describing the rules and regulations of the list, as well as the unsubscribe rules. If you don't like the rules, we can talk, or you can walk. Simple, eh? -spc (We shall see ... )

Northstar S100 compatability

by simon＠nenevr.demon.co.uk

Hi there, guys. I've been lurking on this list for a good long while now, and some of the recent talk of Northstar crates actually prompted me to dig one out that I had aquired a good few years ago and promptly forgotten about...! Does anyone have any idea what sort of RAM cards the Horizon likes to play with? My system already has an (albeit flakey) RAM-16 card, and I have the remains of an old Godbout Econoram-II card, sans about half its chips. I have *no* idea whether this card was ever used with the N*. The machine is not in great condition, bless it; it seems to have been robbed of a couple of voltage regulators at some point in the past, and the full-height 5.25 drives are, I fear, past their best, and shall be retired gracefully. I think that the PSU could do with some adjustment, too; if anyone in the UK has schematics for any of these bits, and would be willing to make copies in exchange for money or eternal gratitude, please let me know! Still, despite it's problems, I suppose I should at least be grateful that I have at least found a manufacturer of hard-sectored diskettes! [1] Thanks.

If they are from a 704, 705 or 709 or ancillary equipment I may have module diagrams. Look for a 4-digit number rubber stamped on the metal on the tube side, also there may be a 6-digit part number. To get an idea of what machine they might be from list the tube types. For instance, the higher performance 704/709 modules used mostly 5965's in the processor. Also look at the parts on the sides, logic modules have resistors and lots of diodes and maybe a few inductors. Other modules will have few or no diodes. One common module from card equipment has a small double row of core memory in the middle near the connector. Paul Pierce http://www.teleport.com/~prp/collect/

Running Classiccmp

by bcw＠u.washington.edu

Yesterday I began talking to people about taking over list functions. The response has been amazing and overwhelming. Before making any decisions, I am going to go over the list archives and attempt to read the list for a week or two to get a feel for what's going on. If you have strong feelings about how the list should be run, or by whom it should be run, please e-mail me directly. -------------------------------------------------------- Bill Whitson bcw(a)u.washington.edu Network Administrator (425) 352-5209 University of Washington - Bothell Help Desk: 2-5275

Robots again

by SUPRDAVE＠aol.com

:::cautiously leaving bomb shelter in order to post::: back in the 1980s, i came across a book that also had a design for a robot dog but i think this was a different book. it was built around a 8085A and 8155 support chips, totally wire wrapped and included schematics for building a programmer to program the robot dog itself. i never did get around tuit, but would have been fun to build. why didnt robots catch on as big as computers did? i remember robots were the thing back in the 1980s like the web is now but never really gained critical mass. there were a few models made, ( hero 1 and 2, rb5x, et al) but nothing really caught on. ::returning to bomb shelter, continuing to delete 97% of classiccmp messages for the moment::: In a message dated 98-03-18 21:28:38 EST, you write: << > >I have here a book from the Philips Technical Library called 'Practical > >Robot Circuits' published in 1960.

To keep it simple there's no 'learning by experience' (the book does mention this in passing) or large memory stores (using only valves and relays, that's not suprising). Looking quickly at the book I can find : 1) Detecting/following a light source (turning its 'head' towards it, moving towards it). 2) Detecting a sequence of 2 tones (its 'name') and coming towards the sound source 3) Detecting that it's walked into something and backing off. 4) Detecting a hot object ('food'), turning its 'head' towards it, licking it. 5) Using a sonar (accoustical radar) system to detect objects and avoid them OK, trivial compared to what can be done with even a PIC microcontroller. But I'd still like to make one one day.... >>

Osborne OCC 1 Drive C:

by adept＠mcs.com

I just acquired a couple of Osborne 1's and one of the two of them has a Drive C: in it. I got some docs with the boxes but nothing describing this exciting little add-on. I've scoured the classic computer mailing list archives and I've found a previous question (from may of last year) on just this topic, unfortunately nobody really knew anything then. Any help or pointers would be greatly appreciated. Cheers and thanks, Dan ps -- I'm currently in dire need of a CRT for a TRS-80 Model 12.

Symbolics 3650..

I know of them from the computer graphics market. (I'd love to get one, if you have two. :-) I think the 3D modeling / rendering software was sold off to various other companies (Triple-I / Autologic) and these days at least the concept of a Lisp-based modeler can be found at www.nichimen.com . The symbolics.com domain is still registered, and by reading between the lines of some messages I found, I think it's owned by some Symbolics enthusiasts or employees in Princeton Junction, NJ. There is/was apparently a related newsgroup or mailing list. Go to www.dejanews.com and search "info.slug" (with the quotes). I found a message that said that Symbolics had laid off its last three employees just this past January, and that the lawyers are fighting over the assets. Good start on your Lisp history page. I have one for UCSD Pascal. - John Jefferson Computer Museum <http://www.threedee.com/jcm>

Web page lists

by kyrrin＠jps.net

Hi, folks, Like most of the list subscribers, I'm a scrounge. To this end, I've placed on my web page listings of electronics and computer-related surplus stores and swap meets in Washington and (northern, Bay Area) California. Oregon (Portland and Vicinity) will be added as soon as I can swing a survey trip there. Hoping these listings may be of use to at least a couple of you, the URL is: http://www2.jps.net/~kyrrin Or... http://table.jps.net/~kyrrin Enjoy... -=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=- Bruce Lane, Sysop, The Dragon's Cave BBS (Fidonet 1:343/272) (Hamateur: WD6EOS) (E-mail: kyrrin(a)jps.net) "Our science can only describe an object, event, or living thing in our own human terms.
