Is anyone here interested in buying a Symbolics MacIvory 2 with 16mw of RAM? I bought this directly from David Schmidt of Symbolics a few years ago and haven't had much time to do anything with it. It came with a Macintosh Quadra 650 and a keyboard with a Symbolics overlay as well as documentation. It is all in working order. I'd like to find a good home for this. If you're interested, please contact me and make an offer. David says that the MacIvory 2 with RAM (maybe only 8mw) costs $999 from him right now so I don't expect to get that much. If you already have a Macintosh that will accept these boards (only the Quadra 650 or 900 I think) we can discuss buying just the boards and not the Quadra 650. That would make shipping much easier and less expensive. Thanks, David

OT: F/S: Lots of books about the history of science and tech

by evan＠snarc.net

I need money. Selling 53 books. These are all books about the history and impact of sci-tech. It's massively time-consuming and tedious to put a value on all of them. So instead I want to sell them as one giant lot. Most of these books are only a few years old and most are in excellent condition. Most of them I bought new. Some of them I bought used, and some have a few notes in them. I could probably make more by selling them individually, but as I said, I need $$ now (and I'm way too lazy to ship all these one at a time!) If anyone wants an instant library of history-of-technology books, this is a great starting point. Asking price: $350. (That's an average of just $6.60 per book. Some of these are worth a LOT more.) - 1491 - ISBN 1400032059 - Best of 2600 - ISBN 0470294191 - AC/DC: The savage tale of the first standards war - ISBN 0787982679 - Age of reconnaissance: Discovery, exploration, and settlement, 1450-1650 - ISBN 0520042352 - American telegraphy and encyclopedia of the telegraph - ISBN 1559181931 - Ancient inventions - ISBN 0345401026 - Blood: An epic history of medicine and commerce - ISBN 067941875X - Clean tech revolution - ISBN 006089623X - Miller's Collecting science & technology - ISBN 1840008490 - Crypto - ISBN 0140244328 - Does technology drive history? - ISBN 0262691671 - Edison: A life of invention - ISBN 0471362700 - Electrifying America - ISBN 0262640309 - German Enigma cipher machine - ISBN 1580539963 - Greatest inventions of the past 2,000 years - ISBN 068485998X - Ham radio's technical culture - ISBN 0262582767 - History of mechanical inventions - ISBN 048625593X - Information appliances and beyond - ISBN 1558606009 - Lincoln the inventor - ISBN 0809328976 - Longitude - ISBN 080271529X - Maps & civilization - ISBN 0226799743 - Map that changed the world - ISBN 0061767905 - Marconi's magic box - ISBN 0306813785 - Meaning in technology - ISBN 0262661209 - Measuring America - ISBN 0452284597 - Nothing like it in the world - ISBN 0684846098 - One good turn - ISBN 0684867303 - Pencil - ISBN 0679734155 - Power to the people - ISBN 0374236755 - Readings in cyberethics - ISBN 0763724106 - Riddle of the compass - ISBN 0151005060 - Science and the founding fathers - ISBN 039331510X - Science of measurement - ISBN 0486258394 - Science in nineteenth-century America - ISBN 0313331618 - Science of Star Wars - ISBN 0312263872 - Scientific instruments - ISBN 0520217284 - Scientific renaissance: 1450-1630 - ISBN 0486281159 - Social history of American technology - ISBN 0195046056 - Steam - ISBN 1422364402 - Structure of scientific revolutions - ISBN 0226458083 - Telephone gambit - ISBN 039333368X - Thread across the ocean - ISBN 0060524464 - Victorian Internet - ISBN 0802716040 - Voodoo science - ISBN 0195135156 - Visions of technology - ISBN 0684863111 - What Einstein didn't know - ISBN 0440508568 - What Einstein told his barber - ISBN 0440508797 - When old technologies were new - ISBN 0195063414 - Why people believe weird things - ISBN 0805070893 - Why things bite back - ISBN 0679747567 - Wilbur and Orville - ISBN 0486402975 - Wireless - ISBN 0262082985 - Writing implements and accessories - ISBN 0810320177 Obviously it would be expensive to ship these, so I prefer a seller in the northeast US.

Need help with Project Northstar/Data I/O System-19/ADM, Terminals (dwight elvey)

by trebor77＠execpc.com

Message: 15 Date: Sat, 18 Dec 2010 06:46:57 -0800 From: dwight elvey <dkelvey at hotmail.com>RE: Need help with Project Northstar/Data I/O System-19/ADM Terminals (dwight elvey) Hi It is unlikely that there is a problem with the 2708s If the programmer said they were good, I'd expect them to be fine. The places I'd look are first the RS232 connection. The fact that the canon book works on one machine doesn't mean it will work on another. As well as the data lines, there are handshake wires that need to have the right levels. He said that he'd single stepped the code, what were the results of that? what did it do or not do right?? Dwight It just goes crazy as the Prom was not burnt correctly Bob Turns out that the Problem is that the Data I/O System-19 I am using doesn't want to load the Hex file as INTEL. It will only load a File if it is flagged as BINARY and that doesn't give a proper code Image. I am trying to get a fellow to see if his System-19 will load the file and burn the 2708 Properly then I can get mine Fixed I HOPE. I also have been Re-Erasing the EPROMs as I go along. Bob

6809, 6502, or 6802 computer

by lynchaj＠yahoo.com

_____ From: Andrew Lynch [mailto:lynchaj at yahoo.com] Sent: Friday, December 17, 2010 6:42 PM To: 'cctalk at classiccmp.org' Subject: 6809, 6502, or 6802 computer Hi, I just received some PCBs for a 6809, 6502, or 6802 computer. The ECB host processor can either be a stand alone computer with the IO mezzanine board Alternatively it be connected to the N8VEM backplane and rely on the N8VEM SBC for IO or do both simultaneously. The computer board supports 6809, 6802, or 6502 CPUs depending on builder preference. You set configuration jumpers for the CPU you select. The 6809 CPU configuration supports the CUBIX, the 6502 CPU supports DOS65, and for 6802 and/or the 6809 there is a FLEX port in the works. More information is available on the N8VEM mailing list and N8VEM wiki. Please contact me if you have questions or comments. Thanks and have a nice day! Andrew Lynch Hi! I've gotten some questions on the N8VEM 6809/6802/6502 computer. There is additional information available on the N8VEM wiki. Over time it has spread out over several folders as the project has evolved. http://n8vem-sbc.pbworks.com/w/browse/#view=ViewAllObjects Please look in these directories for information http://n8vem-sbc.pbworks.com/w/browse/#view=ViewFolder <http://n8vem-sbc.pbworks.com/w/browse/#view=ViewFolder&param=6502%20Host%20 Processor> &param=6502%20Host%20Processor http://n8vem-sbc.pbworks.com/w/browse/#view=ViewFolder <http://n8vem-sbc.pbworks.com/w/browse/#view=ViewFolder&param=6809%20CUBIX%2 0-%20Stand%20Alone> &param=6809%20CUBIX%20-%20Stand%20Alone http://n8vem-sbc.pbworks.com/w/browse/#view=ViewFolder <http://n8vem-sbc.pbworks.com/w/browse/#view=ViewFolder&param=M6802> &param=M6802 http://n8vem-sbc.pbworks.com/w/browse/#view=ViewFolder <http://n8vem-sbc.pbworks.com/w/browse/#view=ViewFolder&param=m6809> &param=m6809 If you've got questions on the N8VEM 6809/6802/6502 computer please either ask me or better yet ask on the N8VEM mailing list. There is a lot of information on the mailing list in the archives. The 68xx/65xx hobbyist community seems rather sparse these days so hopefully this will spur some renewed interest. Thanks and have a nice day! Andrew Lynch

Need help with Project Northstar/Data I/O System-19/ADM Terminals

by trebor77＠execpc.com

I am trying to restore a N* Horizon,. So far I have got the ZPB-A2 CPU card working. I added the Prom Option and am using a 2708 EPROM with Monitor Code by Dave Dunfield. A Friend burnt the Prom for me but I has a problem and doesn't get the Keyboard Input. I have tried several times to Burn a new Prom with my D/I Sys-19 but they don't behave as they should. I have a SOL20 System/Bus Probe Card that single steps from the get go and I can step through the Code and see how it behaves in relation to the .lst listing. I have been using my Canon Book 10 running "TERM" to talk to the N*. It talks OK to the Sys-19 as well as other machines. I lost both of my Televideo 920/25's. I had three ADM LSI's in the Shed/Barn but the Field mice made their nests in two. The one that was untouched I brought in the Other day and It lights up the Mini-Tracker showing that the ADM is setup as DTE. But I get no response >from the Keyboard. Tried looping back 2-3 but no display. Don't see any Raster but the tube POPs up a spot when turned off. I am going to try to pull the Mother board out of the Other Micey ADM. Maybe I can swap the M/B's and see if that CRT is working. Same for the One still in the Barn. What would my chances be of soaking it and getting all the CRAP off it and having it WORK????? probably ZILCH. The third one is still in the Barn but Maybe it can be cleaned up. These terminals haven't been run since 1992. I also have a IBM 3101 a but so far all I found was the Base and CRT. The Keyboard must be in the Barn. Has anyone a spare Terminal. I'm thinking that maybe the Monitor code will work when attached to a REAL Terminal I bought about 5 2708's and If I can find someone who might load the New Code for me I could send them a 2708 and E-Mail the .HEX file.

3B1 emulator: IT BOOTS! (sort of)

by classiccmp＠philpem.me.uk

They say "A picture says a thousand words"... well, here's a screenshot of the current version of FreeBee booting the System Loader and Diagnostics disc for the 3B1: http://i162.photobucket.com/albums/t242/philpem/Screenshot.png And for those who don't believe anything unless they see it moving: http://www.youtube.com/watch?v=Y0sRkJty6wo :) To make this work... * Install the LibSDL (Simple DirectMedia Layer) development libraries, and a C compiler. On Debian/Ubuntu, you want to 'apt-get install' build-essential and libsdl*-dev. You'll also want make, sed, awk and grep, which should auto-install when build-essential installs. On Windows, you're on your own (though a homebuilt SDL and mingw32 should work... in theory). * Grab the FreeBee source code: http://hg.philpem.me.uk/3b1emu/archive/tip.tar.bz2 And the ROM images: http://philpem.me.uk/code/3b1emu/3b1_roms.zip * Grab ImageDisk from Dave Dunfield's website, and the Version 3.51 Diagnostics Disk (.IMD file) from Bitsavers * Use Dosemu, DOSBox, or a conveniently located DOS or Windows box to convert the .IMD into a .BIN file: IMDU 01_DIAGS.IMD 01_DIAGS.BIN /B Copy the BIN file onto the Linux box. * Untar the tarball, and cd into the directory it creates. * make * Copy the disc image in here, and rename it to 'discim'. * Create a directory called 'roms', and unpack the 14C and 15C binaries (.bin files) into there. Rename them to '14c.bin' and '15c.bin' respectively. * Run: ./freebee * Watch the fun. No, the keyboard isn't emulated (yet), no the hard drive isn't emulated yet, and no, it doesn't boot past the RAM test screen... Keyboard is next on the hitlist, followed by interrupts, masking and the MMU/pagefault traps. I'm looking for other folks to help out with this -- a reasonably experienced 68K coder would be useful, or folks who know how the WD 1010 and 2797 Winchester and FDD controllers behave in 'real life' (unfortunately I don't have a 2797 to breadboard with). Enjoy! -- Phil. classiccmp at philpem.me.uk http://www.philpem.me.uk/

PDP 11/24 and VAX 3500 available

by silvercreekvalley＠yahoo.com

I'm thinning down my collection and have a PDP 11/24 and a VAX 3500 available - free but collecton only (UK). The 11/24 could do with a clean, but it looks to be complete and has the often missing power key as well. Internally there are several cards. The VAX 3500 is in a desk side pedestal style case. It has wheels so can be moved. In nice condition cosmetically. No idea what cards etc are installed. Both units have never been powered up by me, and would need to be carefully checked, etc before powering up. Given away as is - for spares or repair. Collection only. Contact me by email if interested.
