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>

I live in Rockwall (20 minutes from downtown Dallas) or I would take them to my office near Baylor hospital. I won't ship; it I was going to ship, I'd sell it on ebay. If it's not picked up by 3/16 or arrangements made for pickup, it's going on the curb for the landfill. -- http://webpages.charter.net/jrice54/classiccomp2.html

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! '...shows ya how much the 'rank-and-file' really know about computers down here... Cheers...

If you are VERY familiar with your home city, you can also scout out the garage sales in communities which were "new" in the 1970s I see things like Mattel Intellivison's, original Apple II systems and such but they always seem to appear in areas which were newly built in the early 1970s. My wife and I attend garage sales all through our city, but only certain neighbourhoods seem to have the classic computers. Still looking for a working Exidy Sorcerer... Thomas
