HP 9845B possibly available in Australia

by dan＠ekoan.com

Hello, There may be a Hewlett-Packard 9845B computer coming up for sale in Queensland, Australia. As much as I'd like this machine, it would be too expensive (for me) to have it shipped from down under to the United States. If anyone closer, or better funded, is interested in this classic machine, contact me off list and I'll give you the details. Cheers, Dan www.decodesystems.com/wanted.html

(Fwd) A 4331 in MA, USA

I just got news about a nice 4331 to be scraped in MA. ------- Forwarded message follows ------- From: "Dom Rodriguez" <dom(a)calldrw.com> To: "Hans Franke" <Hans.Franke(a)mch20.sbs.de> Subject: RE: Ausstellungsidee Date sent: Fri, 7 Mar 2003 14:30:13 -0800 > > We have an IBM 4331 System with peripherals that would like to sell > I assume the Computer is lovated in the US? > Unless it's in Germany, I can't realy do anything. > I took the Producer of the US VCF on CC, maybe he > is interested or knows someone. > Best Regards > H. Yes it is in Massachusetts, if you have any referrals please let us know. It includes tape drives, disk drives, 1401 printer 2540 card reader punch etc Thanks Dom Rodriguez ------- End of forwarded message ------- The 4331 is (in my opinion) eventualy the single most desirable classic /370 Machine for a proivate collector. It's reasonable compact, but got all the bells and whistles of a real IBM of the early '80s. Ok, the odd I/O chanels are a minus, but beside that it can't co better for the spacewise challenged amon us. It looks almost as if he thinks he may still get money, but he might learn soon that he should be happy if someone is willing to pick it up without having him to pay for that service.

MITS Altair 8800a for sale on eBay

by dgari＠msn.com

Joe, The RQM Systems Power-Start boot loader board has 16 'load address' switches (set to C000h), 8 'sense' switches, and 8 each called 'IN 376', 'IN 375', and 'IN 374' (obviously octal representation). There is a 'Board Enable' paddle switch on the right, tons of basic TTL and a 74S472 PROM (512x8 bits) with room for one more. Probably loads the disk controller start code... >Message: 19 >Date: Thu, 06 Mar 2003 19:34:44 >To: cctalk(a)classiccmp.org >From: Joe <rigdonj(a)cfl.rr.com> >Subject: Re: MITS Altair 8800a for sale on eBay >Reply-To: cctech(a)classiccmp.org > >David, > > I looked at your auction.

Dragon 64

Good point. But, I need to know which chip goes in which position... Using your idea, it looks like the two missing chips are the 6809 and the 6883 (which would make sense, as Bob sold those as spare parts). But, I don't think it would be a good idea to put the wrong one in the wrong place, and I still need a set of ROMS. Al

fair price for apple articles

by cb＠mythtech.net

>Apple //gs - $20 each Wanna buy some from me?!? At that price I'll be happy to sell you a few. >Apple //c new in box - $50 If it is really new in box, then yeah, I could agree with that price. But I have seen MANY things claimed as "new in box" that are really "we used it for 12 years, and before throwing it out realized we still had the old box so we repacked it". I have seen very few really new in box items, so I am sceptical to those claims. >Mac Plus - $5 >Monitors - $5 each >Misc. drives - $10 >"scads of software and manuals" - I'm assuming "scads" is worth about $25 I consider all of the above to be "Thanks" prices. ie: they really aren't worth anything, but you feel compelled to give the person something for being nice enough to save you the effort of digging thru the trash to get it. In my opinion, Thanks prices don't really add up. Kind of like coupon actual value prices. Its worth $1.00 during the transaction, but if you add the value up, you find it is worth half a cent. So 10 monitors @ $5 each would not equal $50, but rather maybe $10 if you were feeling good. >Including a "new in the box" //c and "scads" of software? That's what I >would value most in the lot mentioned. Got about 3 moving boxes full of assorted software just a few months ago. All that was headed to the dumpster (I intercepted it on the way). About half Mac, half PC. I also got 2 paper case boxes of IIgs software not much before that, probably 20 or so titles, most in their boxes. All free. >> are large (20" monitors, and 10+ gig drives). The software and manuals, > >We're talking Apple ]['s here. 20" monitors and 10+ gig hard drives do >not even come into the equation. I went under the assumption that it could refer to Mac monitors and hard drives since there are Macs included in the list. Actually, now that I think of it, if we are talking about Apple II hard drives (regardless of size), then those are worth something as they are much tougher to find. >That's where you are completely wrong and why you don't understand my >pricing. The software, as long as most of it is in original boxes with >original disks, is the real prize. Your opinion may vary on this of >course, but the fact is that original software in the box is harder to >find than the machines themselves. And without the software and manuals, >the computer is just a pretty object. Yes, we differ here. You fit into the exclusion that I mentioned. That is, you care about having real copies of software. So to YOU the software might be worth something. There are lots of people like me that could care less about original copies, vs getting an "abondonware" copy off an FTP site or so. To people like me, software is of no real $$ value. What's interesting here is I see your point with your pricing. You consider some items to be of value, that I don't. And vice versa (I find some value in a Woz IIgs). So it just goes to show, when pricing things, you can't rely on one source for info, and you should shop around to figure out the best place to market stuff. Maybe this is why eBay prices are always so high... with the wide audience, they increase the odds of hitting someone that lays value on the item. And I'm still amazed that you would give a decent price. I had thought of you as a person that will always claim things are worth far less than they are just to keep prices down. I miss judged you... it must just really be a pure hatred of eBay instead. :-) -chris <http://www.mythtech.net>

Locating older systems & parts... (was: RE: making disk image s)

by Robert_Feldman＠jdedwards.com

The thrifts I go to here in Chicago are not too bad about desktop systems ($10-$20 for 386/486 boxes, $5-$20 for monitors), but any laptop _starts_ at $50, even XT or AT-class ones. A marginally useable 486 will most likely be $150. I usually don't even bother with the hardware -- I go looking for old MS-DOS software. -----Original Message----- From: Robert F.

PDP-11/34 PSU Yet Again

by jss＠subatomix.com

Well, I finally got around to testing the PSU on my 11/34. I measured at the backplane connectors with no backplanes plugged in. Everything checks out except for the -5V and +20V. Accordingly, the LED at the bottom of the H745 brick (regulator 1) does not light. However, some of the other voltages coming from the H745 (according to the BA11-K FMPS) seem to be OK. Does anything in the machine even need -5V or +20V? If not, can I leave the bad brick in place? I have: KD11-EA, KY11-LB, DL11-W, MS11-JP, M7850 parity, DZ11-A, RK11-D. I'll be adding a RX11 at some point. Someone enlighten me, please. :-) I'm pretty sure I have a spare brick. Also: what are these signals on the 6-pin backplane mate-n-locks? - AC LO - DC LO Something I learned: If you have a H785 brick in your 11/34 BA11-KA cabinet, ignore what the 11/34 and KY11-LB manuals say about battery backup and the rotary power switch. You can indeed have a battery backup with a BA11-K, and the switch on the KY11-LB works as you think it should. You must connect the ribbon cable from the H785 to the corresponding connector on the KY11-LB, or the H785 won't work. You must NOT connect the one-wire connector from the H785 to P4(?) of the AC input box, or else your machine won't turn off, regardless of the rotary switch. Clear as mud? -- Jeffrey Sharp

WTD: AMD or Intel 80387 Math Coprocessor IC

by philpem＠dsl.pipex.com

Hi all, I'm trying to track down a 387 math coprocessor IC for an old 386-based Linux box that's going to be doing a bit of numbercrunching for me. Has anyone here got an AMD or Intel (AMD preferred) 387 coprocessor rated at 40MHz (-40 part number suffix) that would work correctly with an AMD Am386DX-40? No, before you ask, the 386DX does *not* have a built in mathco - the 486DX was (IIRC) the first DX-series chip with a built-in coprocessor. Thanks. -- Phil. philpem(a)dsl.pipex.com http://www.philpem.dsl.pipex.com/

Northstar Single Density Controller info MDC-A4

by melamy＠earthlink.net

Hi all, I have put my Intel MDS system on hold while I await some hardware information in the mail. I am resurrecting the second half of my project which is to get a Northstar system up and running so I can develop the ISIS-II code again. The problem I have at the moment is that I need the schematics for the MDC-A4 controller. I have two manuals on the double density controller but nothing on the one I am using. Does anyone have the manual available with troubleshooting info or at least the schematics. I am more than willing to scan docs I have in trade. I am off troubleshooting the controller because it will not write properly. I can load a fresh copy of DOS, customize the I/O and actually run DOS now, but I can't update and make a new copy because of the write issue. I did manage to fix an Applied Microsystems EM180B Z80B emulator today so I could enter the console code and run things. Thanks! best regards, Steve Thatcher

PCjr 1.44 floppy controller

by nampcjr＠yahoo.com

I am curious if anyone ever had one of the Legacy Enhanced Floppy Controllers for the PCjr, was ever able to duplicate one, or know if it was ever possible to modify the current controller to take on a 1.44mb capacity. I have a Racore unit with a modified 3.5" 1.44mb drive that acts as 720kb, and is fantastic, but would love that extra storage space if available! Brian

Dragon 64

by alhartman＠yahoo.com

oops! Guess that was wrong. I can remember using a Tandy Controller on a Dragon 32 once. But, I guess that one had hacked Coco ROMS. That might be what I do with this unit, hack a set Coco ROMS to go into it, just to get it working again. With a new unit at $35.00, it might not make much sense to try to get this one working again. My Coco III is also dead. Green box with no text. I think the 6809 is bad. At least, that's what I've been told about these units. So, I'd have to desolder it and put another one in just to diagnose it. I may do that some weekend when I feel adventurous. Suddenly caught the old computer bug....

As you say, it never made it to the online catalogue... Also, the plotter I'm on about has definitely been saved now. He's possibly going to give it to his son's school, possible eBay it, or possibly sell it to one of you lot for ?pittance, provided you take it away (from Norfolk). Personally, I don't need/want it, and have no means of transporting it anyway, but the offer is there for the taking.

Dragon 64

by alhartman＠yahoo.com

I've decided to try to get my Dragon 64 running again. I got it from Bob Rosen of Spectrum Projects. He stripped all the socketed chips from it, however. So I need to find a set of Dragon 64 ROMS, and identify what chips go in U19 and U15. I'm pretty sure that the one closest to the ROMS is the 6809E, but not sure of what the other chip should be. What makes this more difficult is that this is not a British Dragon. This is an American one made by Tano Corporation. I wish I had just offered him some money for the original chips way back when... I can buy a whole new Dragon for $35.00 + S/H, and if I can't get a set of ROMS and the missing chip cheaper than that.. I may just do that and keep this one as a spare... I wish I still had the Dragon disk controller also... I know I can use a Tandy Controller, but I think I'll need a different Disk Basic ROM for it. If anyone can help with that, I'd be obliged... Regards, Al Hartman P.S.: On the Apple II pricing discussion in a different thread. I agree with Sellam re the pricing. The buyer could easily resell the items he didn't want on eBay and get the prices that Sellam quoted. And who knows if those IIGS's contain RAM boards or even Super SCSI cards that would be work $15.00 for the RAM card, and $40 and up for the SCSI cards.
