Hello, all: I got a couple of IBM-labeled Tandon drives and a MPI/Control Data drive. The Tandon drive is a standard TM100-2A and the CD drive has the following ID#s -- Part 77711801, IBM Part# 1502060. I'm trying to recycle these in my N* (double density setup). The jumper area is unlabeled on these drives, as is the terminator spot. On the Tandon drive, I found a TRW IC near the floppy connector...it has a designation "516-3-151G"...this seems to be the terminator. Can anyone confirm the placement of the terminator and the jumper block pinout for both drives? Any help appreciated.

Free Computers in St. Louis: PCjr, Apple IIGS and more

by bkotaska＠earthlink.net

I live nearby and may be interested in some of these free goodies if they are still around. I just joined the group so can you contact me? Thanks. Bill Subject: Free Computers in St. Louis: PCjr, Apple IIGS and more I've finally come to realization that I do not need 2 (or more) of every computer I can latch on to. I have a complete IBM PCjr system with monitor and keyboard and several Apple IIGS systems all with keyboard, monitor and floppy drive. I also have some CoCo 2's, TI-99/4A's, some ugly Amiga 1000's and some C-64's. I realize these are aren't the rarest of computers but they are still fun to tinker with and the price is right. These are free for pickup only, I will not ship them. If you're passing through the St. Louis area on I-70 in St. Charles drop me a line and we can arrange a meeting. If you are able to stop by and feel like geeking out I have 300ish computers in the basement including an Atari 1400XL with 1090XL box, Altair 8800, IMSAI 8080, PET 2001 and others that you might like to check out.

HP41 problem..

by jos.mar＠bluewin.ch

My (unexpanded) HP41c developed a strange problem... It still knows how to do the maths, but any value stored inside a register gets lost : i.e. 1234 STO 12, RCL 12 yields 0.000.... Any pointers ( also pointers to a more suitable group ? ) Jos Dreesen

cctech digest, Vol 1 #370 - 5 msgs

by paul.shubel＠verizon.net

> I tend to agree, but I would specialize that even further. As time goes on, > I become more convinced that ALU width should be the determinant of bittedness. > The 6809 requires multiple ALU passes for a 16 bit operation because the ALU > is 8 bits wide. The 68000 is a 16 bit processor for the same reason. > Hi Everyone, I have thought about this topic at length............... This is a much debated issue because microprocessors tend to have 8 and 16-bit instructions, while microcontrollers tend to have instructions that are limited to 8-bit operands. Really, does it matter what size the ALU is in silicon within the chip? I say no! When you are coding in assembly you're interested in what instructions are available to you. For example, the Z8, 8051, 6805, PIC16, etc.. have mainly 8-bit operations with few if any 16-bit operations. Note, please leave 16-bit jumps out of this discussion. The 6502 uses 8-bit operands also. On the other hand, the 8085, Z80, and 6801 are considered 8-bitters in the media but they have 16-bit operations that make them more powerful than the example micro-controllers above. Side note: Since these processors can handle 16-bit operands with ease, pointer arithmatic is very compact. Pointer arithmatic is very important when porting to high-level languages! I consider the 68HC11/6809 complete 16-bitters. Why not! They both have oodles of 16-bit operations, like the ever-useful 16-bit compare immediate! So here is how they stack-up: 8-Bitters: 6502, 6805, Z8, 8051, PIC16, TMS370, ST6 8/16-Bitters: 8085, Z80, ST7 16-Bitters: 68HC11, 6809, 8088/8086, 65816, 80C166, ST9 16/32-Bitters: 68000, Z8000, 80286 32-Bitters: 68020, 80386/Pentium, ARM, MIPS, NS32000 Cheers, Paul

> How was the D-day Museum? I've heard about it and I'd like to see it >some time. It was actually pretty interesting. I didn't expect to enjoy it being as I'm not a history buff (and slept thru most of my history classes). But my wife's grandfather served in WWII and was part of "Omaha Beach" (I'm pretty sure that was the one), so she really wanted to go. I found it to be far better than I expected, and am actually glad I went. It isn't very big, but there are a bunch of videos you can watch, and a TON of stuff to read. You can be in and out in an hour if you want, or 6 hours if you take your time. I think I was in there for about 3 or 4 hours myself. -chris <http://www.mythtech.net>

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

by cb＠mythtech.net

>Except the dumpster is private property. Theft pure and simple, in the eyes >of the law. I'm not a lawyer, but this might be a regional opinion. I know the cops around here at least don't consider it private property unless A: the owner of the land chooses to press charges, or B: the property is some how restricted access or not normally public access. So for example, the dumpster I raided the other day, it was in the parking lot of a publically accessable and open building (a gym, a realtor, and a weight clinic), so the police wouldn't consider that private property unless the owner of the land (unlikely to be any of the tenants) choose to press tresspassing charges. But, the dumpster behind the local good will, probably WOULD be considered that by the police, because it is in the back parking lot of the building (which is not open for customer parking, its only available to the public when they are dropping things off), AND, the entire lot is chained off when the store is closed. And of course curbside garbage is always open season around here. The only time the cops hassle you on that is if you make a mess. But good garbage pickers always make sure they clean up after themselves. -chris <http://www.mythtech.net>

Outbound

by boo＠inksworks.com

Hello, I got your name when I googled for ³Outbound Systems². I have an Outbound Laptop serial# 26700007 that was traded to me by Outbound when I produced their first Œhow-to² video on swapping the ROM. I¹m getting ready to move to the boat and take off and need to trade the computer for $. It is missing the cable that connects it to drive peripherals. It has a unique connector I¹ve never seen and I can¹t find anyone who knows where to find it. I have an external disk drive and the SCSI box. It must have the silicon drive because it needs a disk to boot. Any advice on finding the cable and where best to offer it all for sale? Thanks for your time.

Unibus SMS controller ID help needed

by mross666＠hotmail.com

Hi, Recently bought an 11/04 on epay, seems to be in fairly good shape, it has one mass storage card in it, and it's one I'm not familiar with. Quad Unibus, bright green PCB, made by SMS, model FD1100I. A single ribbon cable, which seems to be identical to a modern 3.5" floppy drive cable, except it's keyed differently - a 'corner' pinhole is filled. Boot ROMs on the M9312 are hand lettered E35-4325 (ROM 1) and E33-4325 (ROM 2). It boots into an apparently standard console emulator. Any clues? The 'FD' part number and the fact that it *looks* like a floppy disk cable might be a bit... obvious! :-) Cheers Mike http://www.corestore.org _________________________________________________________________ Tired of spam?

Power pinouts for Compaq SLT286?

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

by Edward.Tillman＠valero.com

Hmm... And which "Texas" might that be? Sure isn't here... Most of the Salvation Army, Good Will and other similar stores in San Antonio tend to throw away computers and parts. But, you never know when that's going to happen, so ya gotta dive their dumpsters daily. Often, all you come away with is the stench. (Why do they always seem to park these places next to Class-D or 1-star restaurants?!) On the other hand, local pawn shops seem to do a booming business in computers -- and they target an audience of suckers - i.e.: if you want an old 386 or 486 machine, they're available -- if you have no clue about computers, and want to pay similar prices to a new Gateway or HP!! It doesn't make much sense, and a lot of working classic systems just sit around collecting dust, but getting a pawn owner or manager off-center and into reality is an absolute b-tch!

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. Schaefer [mailto:rschaefe@gcfn.org] Sent: Thursday, March 06, 2003 6:02 PM To: cctalk(a)classiccmp.org Subject: Re: Locating older systems & parts... (was: RE: making disk images) <snip> I've heard many Texans on the list say something like `I passed up the quad Xeon box at the salvation army 'cause it only had a half-gig of ram and they wanted 45 bucks for it.' Ok, maybe not quite like that, but the stuff they talked about would *never* be seen in a local store, or priced higher than new. Literally. The local $thrift_store_charities are hell-bent on making a profit, and it bugs the crap outta me to see them selling junk, for obscene prices, to poor people who might not know any better. Whoops-- sorry. </rant> <snip> Bob

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....

HP 5890 gas chromatograph chemstation?

by rigdonj＠cfl.rr.com

Is anybody here familar with this stuff? I picked up a HP disk drive with the ChemStation software installed and I'd like to know more about exactly what kind of computer it was SUPPOSED to be used with. I searched the net and one site mentioned that it used a HP 9000 300 but that's all I've been able to find out. I got the Sw working on a HP 9000 217 but I'm having some problems with the display. Oddly enough, the SW won't run on my HP 9000 320 or 380! Joe

HP 7850B plotter

-----Original Message----- From: Andy Holt >> I know of someone who is looking to dispose of a HP7850B plotter, stands >> about 4ft tall, prints on A0 paper. Located, I think, in Norfolk. >> >There is also one of these in a (live) auction in Southend today. It'll be >interesting to see how much it fetches. Did you see the auction? 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.
