Spring Cleaning - Revisited

by Anthony.Dellett＠Staples.com

Okay, to avoid confusion, I'm going ahead and adding prices to these. Some prices are negotiable, most are firm. $10 plus shipping, the RAM cards alone are worth $10 :) Atari 800 (not working, parts?) $30 each, they work and include cables Atari 1050 Disk Drive (two of them) $30 each Commodore 64 (complete in box, I have two like this) $30 for the working grey one, the broken one is a white one and I'll sell for $10 Commodore 1541 Disk Drive (2 in box, one works, one doesn't) $25 Commodore 1541 II Disk Drive (complete in box) $35 Commodore 128 (complete in box) $25 Commodore 1571 Disk Drive (complete in box) $100, it's in beautiful shape. Compupro S-100 Enclosure (motherboard and PS only, no cards) $600, it works, it needs a DPST toggle switch (whomever owned it before me moved power off the front panel to a toggle switch in back, it broke recently) or you can move the power back to the front panel. IMSAI 8080 With: 8080 Processor Card (IMSAI) SIO4 (Godbout w/docs) RAM64 (Godbout w/docs) PIO8 (IMSAI) $40 Kaypro I (incl. boot disk) $40, this has a third party RTC upgrade in it, it needs new batteries. Kaypro II (incl. boot disk) $40 Kaypro IV (incl. boot disk) Make offer. The cards are in pretty good shape but the disk drives are shot and the power supply needs restoration. NorthStar Horizon (not working) $200. Works perfectly, comes with Graphic CP/M 2.2 NorthStar Advantage (works completely, with boot disk) $20, good for parts. Might actually be repairable. Has the modem upgrade. Osborne I (not working) $50, works great, I have CP/M and P-System boot disks Osborne Executive (incl. boot disk) $300, mostly works, needs a $5 replacement keyboard encoder Processor Technology SOL w/SOLOS personality module $30, cute little all-in-one system Sanyo CP/M System (with software) $30 TI-99/4A Computer (beige model, in box) $60 TRS-80 Model III (with some software) $50, for both 8" DS/DD Floppy Drive (in wooden enclosure) and Controller (Godbout w/docs) 8" SS/SD Floppy Drive (no enclosure) $150, it's a really nice subsystem. 8" SS/SD Dual Drive Subsystem (ICOM) $50 8" Hard Disk Drive in enclosure w/controller (Fujitsu Hard Drive, Godbout Controller w/docs) A couple of things I forgot... $30 Macintosh Portable - Needs a new display cable and battery. Includes carrying case. $50 "Fat" Macintosh - Mac 512K, works great, in original box with original packing. $20 CoCo 2 - Works peachy $30 Epson HX-20 - Brand new, never used.

Why? Because there are a lot more people who want them then there are houses. So the prices go up. You can't fault the people who sell them for not selling them cheaper. Sure, you can lament the fact that there are more collectors out there than there are Apple I's or whatever, but it won't do you any good, and it makes no sense to chastise ebay for creating an efficient way to get those items in front of more people or sellers for using that method to get the most for their items. That's life, my friend. If you don't have the $ to buy on ebay, you can instead work a little harder and find the same things elsewhere for lower prices (our own beloved Sam is an excellent example of this.) If you've got the $, you can be lazy and just bid a zillion samolians on ebay. --------------------------------------------------------------------- O- Uncle Roger "There is pleasure pure in being mad roger(a)sinasohn.com that none but madmen know."

I believe they did it for coins as well. Given IRC or something similar, it wouldn't be hard to do. I don't think web-based live auctions would work; updates wouldn't be live enough. --------------------------------------------------------------------- O- Uncle Roger "There is pleasure pure in being mad roger(a)sinasohn.com that none but madmen know."

Acorn BBC Micros

The Philips 8833 monitors that (at least in Europe) were badged by Commodore and Atari for Amigas and STs work very well. But be warned - the Beeb outputs composite sync, and the centre pin of the RGB connector goes directly to the +5V supply -- which a few monitors don't like. -- Pete Peter Turnbull Dept. of Computer Science University of York

Looking for Sony V7021 IC data sheet and Amiga UNIX questio

Does it actually bear a Sony logo? It absolutely is a Sony part. 28 pin package, pins are on a finer pitch than "normal" DIL ICs, maybe 0.4 wide. On the chip is printed: SONY [the Sony logo] V7021 (C) Asuki [Asuki is in Japanese katakana, not romaji] 142B95K On a related subject, can anyone recommend a cheap IC which I can use for buffering RGB signals, to driving 75ohm-terminated outputs? -- Mark

Do You Have a PDP-11/03L?

You won't do any harm on a genuine DEC backplane; the worst that'll happen is that BDAL18-21 won't be bussed. 11/73S machines were sold in BA11N boxes, which are very similar to the original 11/03 and 11/23 boxes. However, be wary of Plessey backplanes; some of these put 24V or AC voltages onto the "spare" bus lines. > I have numerous BA23 chassis here if you need one but I would > look locally for a MV2 or 3 to save shipping costs.

MicroPDP-11/83s were sold in BA123 cabinets. -- Pete Peter Turnbull Dept. of Computer Science University of York

I have numerous BA23 chassis here if you need one but I would look locally for a MV2 or 3 to save shipping costs. I usually pick up MV2's for $5 to $50 depending on what is in them. Also look for the BA123's. They were only sold for MV's but they make good PDP11 test beds. I have a couple here just for testing PDP11 parts. Dan Burrows
