Way off topic here, and rantish to boot, but just to give y'all a heads up - Don't install Internet Explorer 5. Bunches of reasons, but my big one is this: If you are ill advised enough to uninstall explorer 4, you *can't* get 5 off your system. And at least when I tried it has destabilized my system to the point my desktop crashes about every 10 minutes. I'll be migrating to BeOS as soon as they mail my copy to me. *grumble* On the other hand, and considerably more on topic, the new hobbiest media for openVMS is supposedly going to be available on the 18th of this month from http://www.montagar.com/hobbyist/media.html. -- Jim Strickland jim(a)DIESPAMMERSCUMcalico.litterbox.com ----------------------------------------------------------------------- Vote Meadocrat!

Australia: 8080A chips, eproms, dynamic rams, i/o chips, data books

by davhos＠magna.com.au

I have four 8080 computer systems to dispose of. They were used in a dedicated industrial application - not as a readily reprogrammable system. Some of the chips may however be of use to someone - preferably someone who can collect from Chatswood, Sydney Australia. The main chips are (I am only listing chips in sockets) 4 off 8080A about 200 dynamic memory chips. some are marked 4030, others 4060. they are also referred to as 2107B-4 in the documentation. about 25 eproms type 1702A about 12 off 8212 i/o port chips about 30 off chips marked SN74S412. I cannot find this in my old data book but from the circuit they appear to be doing the same job as 8212 Also available are Intel data catalogues from 1976 and 1977 and a Signetics Bipolar and Mos memory databook dated 1977 David

Yesterday and today I "lived" inside the pavillions of Forli' expocenter where every year take place the Easter Hamfest. I have also picked a Compaq Portable II at 26 Eu (abt.27 U$D) It's a 8086 luggable machine with CRT -> VERY HEAVY! I've also picked: -WISE WY 3216-40 (@ 15 EU no monitor)It's a 386 with the processor and the RAM mounted in two different ISA cards, linked thru a upper connector. The keyboard is the classical WY 160 grey terminal keyboard with mmj connector. The system has a nice LCD retro-illuminated display and a big Megnetic Peripherals MFM (noisy) disk that reached the edge of his days. -C=ommodore PC 20 III (@ only 13 EU, no monitor) mint conditions 3,5 fdd probably a 286. -Some printers (bought not as vintage machines) - HP 320, HP520 (both @ 57 EU) - 2x Epson FX850 @ 35 EU each (they were used by REUTERS somewhere) The man that sold me the Wyse has also a Mannesmann Tally 8 bit optical tape reader @62 EU. I saw a very similar device inside a frontpanel of a automatic plasma welding machine as a numeric controller. I have taken a picture with my digital camera and I will put it on a webpage someday (I just started a HTML/Frontpage course this week) The reader was new inside its carton box and the man told that he still have 15 available. Another couple of yummy think I've seen where a Sinclair ZX 81 and a TIMEX 1000 The bad new where the prices (please seat safetly): 150 EU the first :( and abt. 220 EU the second!!! :o >P.S.: and speaking of today, new members of my junk yard are: snip! >Olivetti CTV 250 Typewriter/Textprocessor (back in the 80s, Olivetti >had the most impressive design, not just grey boxes - I still would >love to get hands on one of these small BASIC able 'handheld' systems >as they where in unse in a lot of Cambio (Money Change) shops - top >notch design and a cute interior) BASIC "handeld"? can you explain more about that? you mean the P.O.S./BANCOMAT small units with thermal printer? In case you like that kind of Oilvetti design, it's possible to contact many wharehouse near Ivrea that stocks also new machines, E.G. the TE550 teletype machine that I've bought new @ 92 EU while 3 years ago it was sold to the National Postal Service @ abt. 2500 EU!! ;D Ciao Riccardo Romagnoli <chemif(a)mbox.queen.it> I-47100 Forl?

Northstar Update

by allisonp＠world.std.com

<I can repair the RAM 16 A3 but I don't have the switch settings and <jumper settings (J) to set it to start at 2000H. What are these? Is that a NS ram 16? I have a mod of the MDS-A3 (SD) controller to put Phantom/ on the bus. However the card has to respect it. The address hole needed for the controller is from E800 thru EFFFh. <Also, I have a RAM 16 A2 board that I can try. Are the switch settings <and the jumper settings on it the same as the A3 to start at location <2000H? Dont ahve them for that card. Never used any of the NS* ram cards. <Finally, will NSDOS run in 16K ram? I see no indication in the manuals <that it won't but it's a good question to ask anyway. NSdos runs fine in 8k! the dos is d00H (DD 3328) or a00(SD 2560) large and starts at 2000. Basic however does fit in 16k but barely. So happens I'm resurecting a NS*Horizon I got a few weeks back. Mine is however working just fine once I set up the serial for my standard setup and to match the Horizon I've had for 21 years. Allison

Mop booting (8) 3100'S ?

by allisonp＠world.std.com

<the /usr subtree. The remaining files under "/" take up around 10-12Megs, <then you'll also need separate swap files which adds another X Megs per <machine. You can probably get by with more of the setup being shared, but Has anyone considered the hack that is done under VMS for small disk impared systems? IE: net or local boot, local swap everything else from the net host. Then the seap drive can be a small 20-40mb drive and the swapping is faster if local even with PIO. that would yeild a fairly fast system that wouldn't beat teh disks to death on the host. Allison

Fancy. I would have loved to have seen graphical LCDs. I've only had the text-mode (with programmable characters) to play with. Have you been to the LCDProc site? (lcdproc.omnipotent.net) It's the one that I'm most familiar with, and is very well along the development chain. > I'm pretty excited.

Acorn RiscPC 600 (OT - only 5 years old)

I once did have a note of what the chopper was -- or rather, I had a part number that worked. I worked for Computer Field Maintenance for a while, and we used to repair them (though they didn't actually fail very often. They seem to be pretty robust). BSR made a copy under license, but the BSR ones don't seem to be so good -- not so well regulated, for a start, so not so tolerant of overloads. > All my Beebs have the traditional Astec SMPSUs.

There is never a number on it. All I can remember is that it's NPN, I think. I'll dig through some old files if I can figure out a way to read the old winchester backups, and see... -- Pete Peter Turnbull Dept. of Computer Science University of York
