I also have a big Symbolics and supposedly some documentation, but I haven't opened any of the boxes so I don't know whats there. I don't have any experience with these machines and don't expect to be able to try mine any time soon, but other than that would be happy to share experiences. I also have contacts in a shop that ran them fairly recently, but they are a startup (of sorts) so don't have spare time to hold our hands. Corresponded with a fellow who has a complete listing of LISP 1.5, we talked about how to get it into machine readable form so it could run on a 7090 emulator. Definitely something I'd like to see happen. If you run across any LISP on 7-track tape I can read it. > ------------------------------ > > Date: Wed, 18 Mar 1998 14:12:28 -0500 (EST) > From: William Donzelli <william(a)ans.net> > To: classiccmp(a)u.washington.edu > Subject: Toobs! > > I now have sitting on my desk six modules from an IBM 700 series > mainframe, destined for the Mill at RCS/RI.

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/

Confidential E-mail

by bcw＠u.washington.edu

If I send any of you messages, I would expect that they will be held in confidentiality. I will certainly give the list a chance to input before making any decisions. If I wished to communicate to everyone, I would post to the list. -------------------------------------------------------- Bill Whitson bcw(a)u.washington.edu Network Administrator (425) 352-5209 University of Washington - Bothell Help Desk: 2-5275

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.
