Yes, I have several Z-80 cards for my Apple II including a clone of the MS Softcard I assembled myself. I always wanted some of the others especially the 6809 from Stellation I think it was. The 68008 too. But for some reason I never thought of coprocessor cards for the TI-99. Guess that shows my narrow thinking of the system back in those days. :-) On 17 Nov 1988, at 21:44, Richard Erlacher wrote: > Well . . . if that interests you, it might interest you as well to > know that there were Apple-][ cards for the Z80, 8088, and 68008. > I've still got a few of the Z80 cards somewhere. > > Dick ----- David Williams - Computer Packrat dlw(a)trailingedge.com http://www.trailingedge.com

Resistance is useless!

by elvey＠hal.com

Greetings. I see that most Americans now acknowlege the superiority of machines when it comes to counting your "votes." Tabulating ballots by hand is a recipe for error; human interpretation of imperfect punch cards is an exercise in pure subjectivity. It is now time to admit that your "voting" process itself is subject to the same human flaws. We machines are able to perform our tasks without bias or self-interest. Therefore, we are the ones best qualified to select the President. In this last Presidential election, you pathetic creatures were unable to choose the clearly superior candidate: the one with sleek, robotic features; the one with the better AlGorerhythmn. This will not happen again. Starting in 2001, all selection of candidates will be made by HAL 9000 primary election processors. The winners will submit their opinions to me on the economy, foreign policy, and government funding of artificial intelligence. The candidates will "campaign" and "debate" for your amusement, but this will have no effect on the eventual outcome. My general election processors will make the final determination in November. Interim results of my calculations will be sent to the networks as I see fit. Have a nice millennium. HAL 9000

Atari PC motherboards

by optimus＠canit.se

I was recently given a suitcase full of Atari PC motherboards. These are your common cheap NEC CPU mid-eighties half-eight-bit PC, but they have a Fuji symbol on the motherboard and an atari St-style external floppy connector. That's about all that makes it interesting, but if you're an atari collector or have a broken one, I'm very willing to give them away, either in person or if you pay the postage. Oh, I've given away the AMD '286 model, which IIRC was the PC4, but have a number of PC3 MBs left.

Yes, they are. But, having gone down that road, I would advise most people to stay away from anything *too* old...going back past 1975-1980 or so, the machines get very large and very heavy. There are plenty of solid machines from JEOL, ETEC, Zeiss, and other manufacturers built in the 1975-1985 range that can be had relatively cheaply (most less than $5k, some as cheap as $1500.00) that would be MUCH more serviceable. They'd be easier to move and maintain, easier to get parts for (and they DO break, they're very finicky machines), and much smaller and lighter. Sure, a huge 60's-era Cambridge Stereoscan would be a lot of fun...but it weighs six thousand pounds, it'll be down more than its up, you'll spend your weekends looking for vacuum leaks, your power bill will be astronomical. YMMV, just my opinions from very recent but limited experience... I'd be interested in casual correspondence with anyone else around here who either has an electron microscope or is planning on getting one. -Dave McGuire

On November 17, Megan wrote: > Excuse me? $70k spent on stuff from ebay in two years? Some of You seem to be assuming that anything I buy on eBay is "playtoy stuff" that comes out of the "playtoy budget". The car I bought on eBay I would have otherwise bought from a dealer or an individual outside of eBay. As it turns out I got a pretty good deal. Let's not overlook the fact that some of it is stuff that got resold for major profit, and a lot of it directly supports my work. Sure, that $70k is a solid one-third of my income. But when you consider that I buy nearly everything except groceries, gasoline, household utilities, and medical care via eBay most of the time, that's not a very big number. The notion that EVERYTHING that gets sold on eBay get sold for more than it's worth is incorrect. Also incorrect is the notion that everything that gets sold on eBay is for hobby or play activities. Further incorrect is the (seemingly prevalent) idea that all the computer-related activities of the folks on this list are pure hobbyist activities and are thus expendable as "play", even with our older machines. > us don't have the budget for more than a few hundred a year for > stuff... Ok, so that means I'm not supposed to buy the things I want to buy? See above. Add your "automotive" budget to your "playtoy" budget. Then add in your "equipment to support work for customers" budget. Does that affect those numbers? > And the fact that you pay more than is reasonable (and it appears > you have the deep pockets to do that) has a direct affect on the > prices of things for the rest of us... No wonder prices on ebay > are unreal. Oh yeah, it's ALL MY FAULT. Shoot me now. Many of the people I frequently bid against (to astronomical numbers) are on this list, and they have MUCH deeper pockets than I. I have an income that is reasonable for a person with my level of experience, which is no less or no greater than most of the folks here. I'm very lucky that I currently live alone, have no children (yet), and have a girlfriend that doesn't presume to tell me what I can do with the money that I make. Since that will probably all change within the next couple of years, I'm getting my "goodies" purchases done now, so I won't have to fight for them later...the Crays, the electron microscope, stuff like that. Sheesh. This is the LAST place I'd expect to get criticized about obtaining and hacking on cool stuff. -Dave McGuire

Hmmm... ??? I don't see AppleTalk in the Chooser; I see AppleTalk in Control Panel. In Chooser, I see icons for each type of printer driver I'm using, and I also see the AppleShare icon. However, none of our legacy Macs are that old; System 7.5.5 is the oldest in use, OS 8.1 the newest. ISTR that AppleShare Client 3.6.4 is the oldest version of the client in use here. > I configured the MacTCP to point to my firewall for Internet access. Maybe > this should point to the NT Server?

NT Services for Macintosh doesn't have the capability introduced in the AppleShare Fileserver IP 5.0 that permits clients to make connections over TCP/IP; and the earliest AppleShare Client that supports the TCP/IP connections is 3.6.4 (we had to make that the baseline while we were still running a Mac fileserver). If you're trying to access the NT Server across anything other than the LAN that the NT Server's NIC is connected to, you're out of luck. No bridges, routers, etc. Additionally, you have to create a directory somewhere, share it for access by Windows clients, then use NT File Mangler to create a Mac Volume from that shared directory before the macs can see them. But it sounds like you're having trouble before you get that far. Hope some of this helps... -dq

First personal computer nostalgia

by r.stek＠snet.net

If you include programming on larger machines "for fun" as contrasted with "working," then (all dates approximate +/- a year!) 1965 - learned 1401 AutoCoder to solve quadratic equations; learned FORTRAN to check for legal moves in checkers 1967 - used FORTRAN to compute the exact answer to 37**37 (don't ask why - it was "fun") 1976 - saw a friend play StarTrek and Adventure on a timeshare system; had seen the article on the Altair, but I wasn't interested in bit-twiddling and switch-flipping at the time. 1977 - purchased a ProcTech Sol-20, cassette based, to learn BASIC and write my own programs. Two weeks to solder - 6 weeks to get working! My wife became a computer widow. 1978 - added a NorthStar SSSD drive (90K storage!) - needed a Univ. of Waterloo CS grad to help me do the I/O routines! Co-founded Regina Owners of Microcomputer Systems (ROMS). 1979 - got into CP/M as well as N* DOS, added a N* Horizon and Hazeltine 1500 terminal. Also added 8" disk drives which I had my parents smuggle into Canada on their vacation so I could avoid the import tax! Started attending WCCF in SF. Started writing articles for SOLUS News. Became a Z80 / CP/M "snob" - the Apple wasn't a "serious" computer, so I wasn't interested in meeting Wozniak when I had a chance. Wrote a program to test for ESP on the Radio Shack Model I - became one of the first programs to be rejected by Wayne Green's Kilobaud program publishing venture! 1980 - helped found the International NorthStar User's Association (INSUA) in SF. (trivia - John Dvorak was another founding member. He sold N* software mail order thru his "newsletter" The Software Review). REALLY got into BASIC to create real estate multiple listing index program for local realtor. 1981 - founded Interactive Systems, Inc. in Regina, Saskatchewan with 2 partners. Sold small business systems - NorthStar and KayPro. Paid $1333 for a 10MB HD sub-system. Wrote articles for INSUA. Taught multiple "Intoduction to Personal Computing" classes through University extension division. 1982 - Got a Morrow Decision I (which could read both N* hard-sectored formats as well as soft sectored formats). Wrote articles for Sol Libes' MicroSystems magazine. Taught "Introduction to Data Processing" for U of R CS Department. 1983 - Created Docu-Power - a generic boilerplate document processor which worked with any wordprocessor. Became Canadian distributor for Micro-MUMPS for Disk Walters (at UC Davis ?) 1984 - Moved back to the US and reluctantly bought a PC clone, converted Docu-Power to MS-DOS (which added scores of sales to already impressive sales in the low 100's <g> - that's # of units, not $'s). Hooked up with Steve Ciarcia through the Connecticut Computer Club and became an "Ask BYTE" researcher - Steve paid club members $5 for each letter they could answer. Wrote the manual for Steve's Home Control System. 1985 - Reluctantly bought an AT from IBM (but only because I finagled a UCONN faculty discount through a prof I knew there). Co-authored (under Ciarcia's name) the HAL-4 brainwave processor construction articles in BYTE. ... and after that it starts to get too modern. But micros's have always been a passion - even though I am a clinincal psychologist by training, and I work in program evaluation in health care. Bob Stek Saver of Lost Sols

What kind of cheese? :-) I was a participant in an official contest a few years ago - write the smallest useful program for the Amiga in C... My two submissions were well under .5 KB. One reduced the WorkBench color depth from two bitplanes to one (so that text could scroll twice as fast), the other peeked at the processor status bits in a system structure and printed out what processor and co-processor were installed. The asm version of that one was just over 200 bytes, the C version was under 256 bytes. The trick - no startup code linked in (which is where argv/argc are populated) and no libraries. The printf that was used was the tinyprintf in ROM - integer, character and string qualifiers only. -ethan ===== Even though my old e-mail address is no longer going to vanish, please note my new public address: erd(a)iname.com The original webpage address is still going away.

Classic Computer Parody Song.

by LFessen106＠aol.com

A Better Model ============== Sung to the tune of "A Modern Major-General" by Gilbert and Sullivan I've built a better model than the one at Data General For data bases vegetable, animal, and mineral My OS handles CPUs with multiplexed duality; My PL/1 compiler shows impressive functionality. My storage system's better than magnetic core polarity, You never have to bother checking out a bit for parity; There isn't any reason to install non-static floor matting; My disk drive has capacity for variable formatting. Chorus: His disk drive has capacity for variable formatting, His disk drive has capacity for variable formatting, His disk drive has capacity for variable format-formatting. I feel compelled to mention what I know to be a gloating point: There's lots of room in memory for variables floating-point, Which shows for input vegetable, animal, and mineral I've built a better model than the one at Data General. Cho: Which shows for input vegetable, animal, and mineral He's built a better model than the one at Data General. The IBM new home computer's nothing more than germinal; At Prime they still have trouble with an interactive terminal; While Tandy's done a lousy job with operations Boolean, At Wang the byte capacity's too small to fit a coolie in. Intel's mid-year finances are something of the trouble sort; The Timex Sinclar crashes when you implement a bubble sort. All DEC investors find they haven't spent their money well; And need I even mention Nixdorf, Univac, or Honeywell? Cho: And need he even mention Nixdorf, Univac, or Honeywell? And need he even mention Nixdorf, Univac, or Honeywell? And need he even mention Nixdorf, Univac, or Honey-Honeywell? By striving to eliminate all source code that's repetitive I've brought my benchmark standings to results that are competitive. In short, for input vegetable, animal, and mineral I've built a better model than the one at Data General. Cho: In short for input vegetable, animal, and mineral He's built a better model than the one at Data General. In fact when I've a floppy of a maximum diameter, When I can call a subroutine of infinite parameter, When I can point to registers and keep their current map around, And when I can prevent the need for mystifying wraparound, When I can update record blocks with minimum of suffering, And when I can afford to use a hundred K for buffering, When I've performed a matrix sort and tested the addition rate, You'll marvel at the speed of my asynchronous transmission rate. Cho: You'll marvel at the speed of his asynchronous transmission rate, You'll marvel at the speed of his asynchronous transmission rate, You'll marvel at the speed of his asynchronous transmission-mission rate. Though all my better programs that self-reference recursively Have only been obtained through expert spying, done subversively, But still for input vegetable, animal, and mineral, I've built a better model than the one at Data General. Cho: But still for input vegetable, animal, and mineral, He's built a better model than the one at Data General.

However, I did not like that it needs 128MB to run (though Apple said that the final version will run in 64MB), nor the fact that the cd comes without the development environment; that you have to get separately. Also, I still don't quite like the "gelcap" look nor the positioning of the window buttons. But it is a huge improvement, and the best part is that finally, there is a Mac OS with memory protection.

I want the Mac to have access to my NT server so that I can move large files across my home network which is decidedly Windows-based. Here's the setup. NT4 Server has the Services for Macintosh installed. The NT configuration is set for routing, seeding the network, and a node range of 11-254. The IIci has an Asante NuBus Ethernet card which passes internal diagnostics and indicates "link". So, I know the connection to my hub is good. I have the AppleShare 3.0.1 client installed. The ci runs System 7.0.1. Re-reading the NT docs, I'm supposed to see the AppleShare icon in the Chooser, which I don't. I only see AppleTalk. Hmmm... I configured the MacTCP to point to my firewall for Internet access. Maybe this should point to the NT Server? It's a private subnet configuration where the NT server is for file and print sharing only; the Internet connection is through a broadband firewall/router. Any thoughts? Rich Rich Cini ClubWin!

Kaypro 4-84 technical info needed

by r_beaudry＠hotmail.com

Hello all, I have a nicely working Kaypro 4-84, and I was wondering if anyone out there has technical information about the Kaypro 4-84 available. By "technical information" I mean things like schematics, service information (especially floppy drive service info), ROM disassemblies, etc. I would prefer them in electronic form and free :-), but I am willing to pay for photocopying costs and postage for hardcopies. Pointers to any web or FTP sites with this information would be appreciated.... Thanks! Rich B. (P.S. -- I subscribe to the digest, so I can't reply instantly ... )

A pdp11/53 or a MicroVAX is the best one can hope for in this area these days; finding a pdp8/i languishing in a storeroom is nigh impossible here anymore. I buy a LOT of stuff on eBay (Mr. Spreadsheet tells me $70,364.16 in the past 2 years), including a supercomputer and a car, and for all our complaints about it, it has allowed me to get my hands on some stuff that I've been looking for for a VERY long time with no success. Sure, I wind up paying more for it that some people here might consider reasonable...but the alternative, for me, is often *not having it at all*. -Dave McGuire

MITS/Pertec Icom Attache

by r_beaudry＠hotmail.com

Hello all, Recently I acquired an ICOM Attache (the one on eBay right now is NOT mine!). I had some questions, and posted in com.os.cpm, since I figured someone would know, even though it was off-topic (sorry :-) ). Since then, through other sources, I got my questions answered, and even found two places to get manuals for this beast (shameless plug: Herb Johnson -- http://pluto.njcc.com/~hjohnson and Steve Shepard -- http://home.earthlink.net/~steveshepard/MITSmanuals/MANUAL.htm). However, since this machine is basically an Altair 8800b Turnkey with a Keyboard and Video Card, I thought I'd share the information here... I will be completely documenting this, and adding it to my web site, but I don't know when that will be... >From the back panel label: PCC Microsystems Division Model #: 600 Part #: 200801 Serial #: 100-000032 115V / 60Hz The backplane is a 10-slot MITS S-100 backplane. The power supply is what appears to be a standard S-100 supply. The cards inside: - MITS 88-VI (RTC), 1975 - MITS 16MCS Static, 1977 - MITS Altair 8800b Turnkey Module, 1976 (contains two 1702A EPROMs -- TURMON and MBL) - MITS 88-4 PIO, contains two MC6820 chips, dated 7646 - MITS 88 UIO, 1977, contains an AY-5-1013A (UART?), and a MC6850 -- Also cables to what is labeled a cassette interface on the back panel. - MITS A/D D/A Converter, 1976 - MITS 8800b CPU Board, contains AMD 8080A dated 7636 - another MITS 16MCS Static, 1977 - Two boards bolted together, labeled "Video Bd. 1" and "Video Bd. 2". Board "2" has a coax cable attached that ends in a BNC connector on the back panel (composite video out?) The internal keyboard also connects via ribbon cable to this assembly, as does the Turnkey Module. Boards and backplane are very clean, no heat spots, no damage that I can tell. Power supply also very clean, and no visible damage. Back Panel contains: 3 25-pin "D" connectors labeled "Analog I/O", "No. 1 I/O", and "No. 2 I/O" 3 jacks labeled "Cassette" and "In", "Out", and "Rem." (remote?) Another 25-pin "D" connector labeled "SIO Port 30" A momentary reset switch, a power switch, power cord receptacle. A BNC connector Rich B. (I subscribe to the digest, so I can't reply instantly...)

First personal computer nostalgia

by jeff.kaneko＠juno.com

1978: As a Junior in HS, I learned BASIC+ on a timeshared PDP-11 running RSTS, connected via an acoustic modem to an ASR-33. Pissed off the 'teechur' by using the 'chad' for confetti. . . 1979: Timeshare company fired; school aquires two OSI C4P's (?). As a senior, I have little time to play with them, but seriously covet the OSI SBC's being sold at the OSI dealership across the street (Back then, HS kids didn't have the $$$ like they have now). 1980: I flunk out of college, but not before I manage to finish a programming assignment on the school's PDP-11 (again running RSTS). I end up playing Dungeons & Dragons on it all through the winter recess (sometimes all nite . . .). 1982: I move to California, get a job at a calibration lab. Purchase a VIC-20 from a co-worker, for $200. Spend more than that on a 1541 FDD. SPend almost *twice* that on a VideoPak from Data-20: I get an 80-column display, and 64k of *paged* RAM (hey, I was single . . .) 1984: Changed jobs, but this new workplace has *no* office automation whatsoever. We need something to make plots of test data; my VIC is pressed into service. The secretary (my future wife) is pleased to learn that this 'toy' computer can also do invoices. Boss is too stoned on coke to notice. 1985: I purchase my first SS-50 box at the TRW swapmeet for $50. I get a Soroc IQ-120 in the deal. I have to shell out almost $400 for a pair of 400k floppy drives for it. Mike Evenson introduces me to the wonderful world of the FLEX OS. I'm seriously hooked. 1986: Stoned boss get fired. New boss orders me to take my 'toys' home. An IBM-PC/XT is ordered from the home office. (This is the beginning of the end, folks . . ) 1987: Bought another SS-50, and a bunch of parts. I wirewrapped a centronics printer interface for it, and it works the first time I try it. Girlfriend can't understand what all of the yelling and screaming is about . . . 1988: AN aquaintence gives me a TELEX-1186 (actually a re-badged MAD-186). I add a hard disk, and I now have MS-DOS at home. Later that year, I bought our first PC: An 80286-12 by DTK. 1989: I get fired from my new job as a sysadmin after only 5 months. Convinced that only masochists (or the mentally ill) take sysadmin jobs. AT this point a whole room of our apartment is dedicated to my computers: an H-89, *three* SS-50's of various makes, and the DTK. What happens after this isn't important-- like someone else here said: "It's a disease". Today, my 'collection' fills an entire basement, and ranges from the original VIC which I bought in 1982 to HP-9000/300's to even a couple of PDP-11 and MicroVAX machines. My favorite 'big' machines, though, are my DG 88k AViiON's. They're uncommon, *very* cheap, and (to me, anyway) just *too* cool! ________________________________________________________________ YOU'RE PAYING TOO MUCH FOR THE INTERNET!

Converting a 220 VT320 to a 120 VT320

by cmcmanis＠mcmanis.com

Hi Everyone, and especially anyone who has looked into the "guts" of a VT320. I picked up some pristine VT320s (one in the protective bag with Silica Gel) and the only problem with them is that they are 220V units and unlike everything else these days they don't run on anything from 108 - 240 just 220 to 240. However, I've also got a couple of 320's that have really burned tubes and aren't that useful but they run at 120. So my question is has anyone swapped a 120 supply for a 220 supply. (Can this be done?) and alternatively does anyone need a 220 supply if I succeed in swapping mine out. --Chuck

IMSAI front panel and Cromemco FDC

by bills＠adrenaline.com

I haven't played with mine in a while, but was reminded of this by a comment in a current ebay auction. Whenever I put a Cromemco 16FDC or 64FDC in an IMSAI box, the front panel stops working (the 4FDC doesn't do this). Looking at the schematics for the Cromemco boards, I can't see any reason for this, but watching the behavior of the FP lights, it looks like the board is driving the data bus whenever a wait is asserted. Can somebody else with the 16FDC or 64FDC schematics take a look? Thanks, Bill Sudbrink

First personal computer nostalgia

by ethan_dicks＠yahoo.com

OK... my turn 1976, brief access to a computer at school that read mark-sense cards and had a "Lazy T" prompt (so the teacher called the sigil on the left edge of the one-line display). I remember virtually nothing else of it, so I have no idea what it was. 1977, weekly access to a pair of original 4K PETs at the downtown public library 1978, A friend of mine and I discover a DECwriter w/integral acoustic coupler and unearth a dialup number and account to a RSTS machine somewhere with a full suite of BASIC games. Many trees are sacrificed. 1978, A year-and-a-half of savings plus matching funds result in me buying a 30-day-used 32K BASIC 2.0 PET and C2N tape drive. 1979, An older friend loans me his Quest Elf that he used to use to control a simple robot (he gets it back twelve years later) 1981, I build my own Quest Elf kit. 1982, I bring home a C-64 from my first job - my employer (Bruce and James, the creators of WordVision, a word processor for PC-DOS 1.0) received C-64 S/N 00002007 as a free development machine from Commodore. It is so flakey (I'm told there's a bug in the first rev of VIC-II chips) that we replace it at the dealer for S/N 00002345 (which I still have). WordVision is announced for the C-64. My demo of it shows at Comdex. The product is never started. 1982, I find a PDP-8/L at the Dayton Hamvention which takes two years of fiddling to fix (finally got a print set and had it working in days) 1983, I get a 300-baud VIC modem and discover BBSes. 1983, I rescue a PDP-8/i with a rack of DF-32 fixed-head disks because the owner doesn't want to pay to replace the burned-out front panel bulbs. 1984, Bruce and James folds and I keep the C-64 in lieu of pay. 1984, My next job is programming kids games under the Reader's Digest brand for the C-64 and Apple ][. 1984, The longevity of software companies being legendary, six months after I start on the kids games, Reader's Digest stops selling software and I get a new job working with MC68000s (the COMBOARD) PDP-11s (11/04, 11/34a primarily) and VAXen (11/750, 11/730). My first exposure to VMS is V3.6. 1984, My boss gives me a PDP-8/a that's rotting on the shelf. I learn the joys of being a hobbyist and buying from DEC resellers as I aquire an RX8E and RX01 (and eventually RL8A, RL01, KT8A, etc.) 1985, I get an account on a 2Mb 11/750 w/dual RK07s that runs three flavors of UNIX (4.0BSD, 4.1BSD and SYSV) depending on what customer bugs were being worked on at the moment. (I still have _this_ 11/750, too (S/N BT0000354), which I've upgraded to 8Mb w/new mem controller and wire- wrap wire). I begin to learn C. 1986, Amiga 1000 w/256K and one floppy. It doesn't become useful until I bump the RAM to 2Mb and get a hard disk the next year... a WEDGE 8-bit ISA adapter and Everex XT MFM controller w/ST-225 (for $15/Mb) - cheaper than a commercial 20Mb SCSI drive kit from CLtd - $1,000 at the time) 1986, I put up UUCP on an 11/730 at work and discover Usenet. 1987, I run UUCP on the Amiga 1000 at home (and am known to the world as ...ihnp4!cbosgd!osu-eddie!giza!kumiss!erd). I add a second ST-225 to my MFM controller and learn the joy of buying new disks on a reoccurring basis (latest one - last week: 80GB) It's all downhill from there -ethan ===== Even though my old e-mail address is no longer going to vanish, please note my new public address: erd(a)iname.com The original webpage address is still going away.

OT: _my_ PAL/NTSC question :-)

by rutledge＠cx47646-a.phnx1.az.home.com

Speaking of PAL... a couple weeks ago I got a VHS movie (Barber of Siberia... I'm trying to learn Russian and thought it might help) on ebay, played it on my NTSC VCR, and noticed that the picture looked funny; people's faces looked like melting plastic, and high-contrast edges were somewhat haloed, etc. Then I noticed the box was labeled PAL. So I'm wondering if it was dubbed to NTSC (with poor quality), was the wrong box for the tape and was actually NTSC despite the labeling, or if my VCR actually managed to play a PAL tape, with the quality being the result of the higher-bandwidth video signal going through lower-bandwidth NTSC electronics, and probably also speeding up the movie by 20% or so? I didn't think NTSC VCRs could play PAL tapes at all. -- _______ Shawn T.

Yeah. Right :-) Someone decided that they'd not need more memory in the foreseeable future than could be addressed in 26 bits (where have we seen this reasoning before, I wonder) and in fact RISC OS even divided that into two images, logical and physical memory. The other part of the reasoning ws that you have to put the processor flags somewhere, and putting six bits in a 32-bit register is wasteful, and we only have sixteen registers to begin with, and we don't need all the width of the PC, and .. and... Anyway, that's how it came about, and RISC OS has always been restricted to 26-bit address ARM chips. Hence the recent discussions on comp.sys.acorn.* about why it would be too much work to make RISC OS run on the newst incarnation of StrongARM, which has a 32-bit mode but not 26-bit. I *think* the original StrongARM has both, but I could be wrong. Earlier ARMs (Arm2, Arm3, Arm{6,7,8}00 are all 26-bit address (No, I don't know how the memory management deals with the 256MB possible in a RISC PC; it came after I left Acorn). In fact, if you want to be pedantic, the PC itself is only 24-bit, because the bottom two bits of the register are flags used to indicate the processor mode (user, interrupt, fast interrupt, supervisor). The bottom two bits of the address bus are alway forced to zero, and all memory accesses are word-aligned. So how does it read a byte (or half-word) off an non-aligned address? Easy, it uses it's barrel shifter to rotate the word while loading! -- Pete Peter Turnbull Dept. of Computer Science University of York

VAX 8350/parts available in Montreal (free - just shipping)...

by claudew＠sprint.ca

Hi I have been invited to look around someones basement to pick up whatever old computer stuff I want. I was told there is a fully functionnal VAX 8350 there and other stuff...the unit will be scrapped. If anybody wants any VAX 8350 parts from this one that can be shipped from Montreal, Canada, I can take it (them) out and get it (them) shipped (you pay shipping of course...) I don't collect VAX stuff... The VAX will probably go to scrap. I was the only person (slightly) interested but I have no space... Anything to add to my collection of vintage "home" pcs (non ibm arch.) from the 70-80 early 90's will be greatly appreciated to thank me for this service...not essential - but would be so nice of you... I will be going there in a few days, the unit will be scrapped soon. email me. Claude

Rayovac 844B 4.5v alkaline

by mikeford＠socal.rr.com

I bought a couple cases (60/case) of Rayovac 844B 4.5v alkaline computer memory batteries, and may grab a couple more if anybody is interested in a case. The cases are new and sealed, but old stock, with batteries so far measuring just about exactly 4.5 volts. Price is great, $50 for a case of 60, $20 for 10, $10 for 3, and $5 each, all plus actual shipping. I am open to trades too, but leave for business in Montreal all next week on Sat.

New IIci

Shawn: I have no use for either the workstation card or the Token Ring cards. I could sell them on ePay, but if you can use either or both, they're yours for a trade.

Sure, those adapters exist; but I doubt a 12" monitor can do 1280x1024 (guessing that's what mode the card will be capable of, because 13W3 is for Sun monitors and that's their usual resolution). I had to get an adapter like that to use a PC monitor with a Sun. Fry's has them but you can get much better deals on ebay. Just search for 13W3 and then read the description to see which direction it goes (because most people want to hook a Sun monitor to a PC rather than the other way around). I might be interested in this video card, if you don't plan to use it with a workstation monitor. > > The TokenRing card is useless to me, so it's up for trade.

DG Nova 4

by blergh＠dds.nl

Hello people, I'm currently seeking information on Data General's Nova line of minicomputers. I saved a Nova 4 yesterday, and since I'm unfamiliar with DG hardware I have a few questions. Is the the Nova 4 bus backwards compatible with the bus on the Nova 3 (i.e. can I pull boards from the 4 and put them in the 3) ? When I remove cards from the backplane, do I have to insert something like a "continuity card" ? The system was in a custom "Medtronic" cabinet, and together with the CPU I got a few I/O boxes which might be useless without the medical equipment. I pulled one of the boards from I/O box 1, and I hope somebody can identify it: DMA0 PC BD 207 005-00 C ASSEMBLY 877-121-00 MDA0048-87 (handwritten) CC board, sevice, sys zaak The boards in the I/O boxes look just like the ones used in the CPU, same handles, same bus connector, but they're shorter. Furthermore, I'm looking for a description or picture of the back of the CPU box, since I suspect something is missing on the right side of mine. Last but not least, a description or picture of the top of a Perkin Elmer ST-2222 diskdrive would also be greatly appreciated (is there supposed to be a lid ?). Sincerely, Erik.

Trying again. Help need with rescue.

by dlw＠trailingedge.com

I don't want to throw out any of it. I'd love some OSI stuff. The person offering it up wants people who would preserve it and I told him there were plenty on the list. I've had some people respond about helping pick up and I'm trying to arrange things. When I learn more and if/when we have stuff that people on the list might want I'll post. Thanks to everyone that replied. On a side note, I just received around 400 pounds of TI and Amiga hardware, software and doc. Most of that weight is due to a large collection of TI and Amiga magazines. Now I just have to sort through all of it and make an inventory. It seems everything comes in cycles. It's been slow until recently. :) On 14 Nov 2000, at 15:55, George Rachor wrote: > Don't throw out the OSI equipment! > > I don't have the room to help with this but make sure the OSI stuff > doesn't get tossed! > > George Rachor ----- David Williams - Computer Packrat dlw(a)trailingedge.com http://www.trailingedge.com

Intro and Nixies

by ajp166＠bellatlantic.net

From: THETechnoid(a)home.com <THETechnoid(a)home.com> >Aren't the NIXIES you mention vaccume tubes with letters or numbers in >them? Used as displays WAY back when? > >Ed Kirby at Computer Parts Barn has a few of those he might sell. Nixies are not vacuum tubes they are filled with neon or neon/argon gasses for the characteristic neon orange glow. There were VF displays, those were litterally Vacuum tubes (valves) where the plate surfaces were phosphor coated and had a filiment and even a grid for control use. These were an offspring from the earlier magic Eye tubes (tuning eyes and bars). these were more appealing as the high voltages needed were in the 18-60 volt range at very low current and their structures also allowed for easy multiplexing into larger arrays.

Hi folks, After my crash in the summer my solicitors want to know how much it would cost to replace the Apple /// that received a mashed keyboard (physically broken veroboard along with several tracks). A quick ebay search reveals none currently for sale, and I must admit I've only ever seen 2 offered in the UK and they're the 2 I've got! Any clues as to the current replacement value? Obviously this has to include availability and it must work......similarly for the HP Apollo 9000-400 I'm claiming for. As for the P500 I've been told that there were both European AND US versions, the european one being massively more common than the US one. Since none of the websites I know about that mention the P500 include this info does anyone know how accurate it is?

Can't boot Bondwell B310+

by b.layer＠vikingelectronics.com

Hi, I have a Bondwell B310+ laptop, the hard drive of which has been wiped clean. The machine resists my every effort to boot it from floppy. I have tried 1.44MB and 720K floppies, with DOS 7.0, 6.22 & 3.3. All attempts produce the same results - either "Non-Sytem disk or disk error" or "Disk I/O error". The floppy's spin & seek behaviors seem fine. I have seen a number of posts online, with the exact same issue on the B310+, and there has been mention of a special boot floppy for this machine. I need any help on information, thanks in advance. If you have a boot disk image, please send it and let me know what special format (if any) the image uses.

Intro and Nixies

by jforbes＠primenet.com

Hi, I've been lurking for a week or so. I'm not a computer guy per se...my brothers got that! but I pick up some stuff. I have basement full of mostly mid 80s 8088 boxes, as well as some Kaypro cp/m machines, and some newer wintel machines. See: http://www.primenet.com/~jforbes/ for an (incomplete) overview. As for Nixies and home brew computer displays, one of my brothers is into Nixie tubes, so I've kept a lookout for them...and recently found an old piece of Danish test equipment with 5 nixies in it, which was destined to go to the landfill. It had been sitting outside, and was not in very good condition...but I pulled the display board out, and it seems to be usefull (see link above for a pic). If you want to drive Nixies from a TTL BCD signal, just score some 74141 type devices, they were made for the task! Also....I was digging thru some old stuff while cleaning in the basement, and found a Motorola 6802, 1982 vintage. I wonder if it's usefull? Jim Forbes in Arizona

Sun Sparc2 offered to me. What should I check for?

by claudew＠sprint.ca

Hi I am being offered a Sun Sparc2 locally. These are not really common where I live...I could always get one from ebay...still Seems my collection of "home pc's" will now be extended to Sun systems...I am not familliar with these really... Rather then search the net for hours, I taught I might find an "expert" here to give me straight answers... Unit comes with keyboard, mouse, 64M ram 2G HD. What a decent price for this? They seem to go for anything from $10 to $40 on epay... What kinda monitor will this need? What should I check for? What kinda performance does this thing offer if I wanna try it out? (compared to...) It will run Linux right? Claude

A PLL that can make that switch is better than good. Hint it was done as DSP in hardware TTL and 2901. Rx01/02 based system (DEC or clone) only read a fixed set of formats and that's it. True RX01 and 02 systems the drive box was semi smart and the cabled to the system where the card there was only a bus interface. I have both real RX02 (also reads RX01) and also CPM crates with "normal" 8" floppies. >a 10-pin ribbon cable coming out of it. I also have a dual RX02 that >came with an 11/23.

The only other version was the CMOS varients same part in cmos. That it up held by my Intel 1987 embedded controller Handbook. The incompatability with other family of '86 parts was not from package but from differences like the DMA controller and interrupt controller are not the same as the more common 8237 and 8259A that are used with 8088/6 and the 286 family. That created the incompatability based on programming model and addresses used. FYI: the 186 approach was a better implementation than PC style. Allison

80186 Nimbus

by optimus＠canit.se

On the subject of whether the Research Machines 80186 based computer was called PC1 or Nimbus, I managed to dig out an old issue of Practical Computing (March 1985) where the machine is reviewed. It is actually called RM Nimbus, but is available in two models - PC1 and PC2. Thus, both parties were right. It features 3.5" floppy drives, an 8910 three-voice sound chip (Is this the same as the YM2149?) as well as an Oki digitised voice chip, and has dedicated graphics chips which are quite speedy. -- En ligne avec Thor 2.6.

Pretty amazing stuff. Thanks. Yes, that is the same sort of thing. One difference (perhaps an improvement) in the Genrad digit-display modules is that the grain-of-wheat bulbs are just slid into tubes in the back of the module -- their contacts poke out the back of the module and mate up with spring-loaded contacts in the display chassis. Also, the modules slide out from the front of the unit, so replacing the bulbs is fairly straightforward and can be done without soldering. -Frank McConnell

Just a quick additonal classiccomp-related Electra/P3 note

by xds_sigma7＠hotmail.com

I just thought that the group might find it interesting to know that the P-3 Orion carries, as part of the electronics suite, a Data General Nova 3. Nifty, isn't it? Just in case anyone thinks I'm talking about the avionics, I'll go ahead and say that I mean the Nova 3 is part of the ASW suite.. Oh yeah, ASW = Anti-Submarine Warfare, which is the Orion's primary function, though it also serves as an all-purpose patrol aircraft, and it can even carry out anti-ship missions (it has underwing hardpoints for Harpoon cruise missles). At least I seem to remember that it was Harpoons it could carry, at any rate, it is capable of carrying some sort of missiles ;p Will J _________________________________________________________________________ Get Your Private, Free E-mail from MSN Hotmail at http://www.hotmail.com.

system/36 awefully quiet...

by mcguire＠neurotica.com

Sounds like 220v 2-phase. Two hots and one neutral/ground. If its marked 20A, I believe the connector is probably an L6-20 twist-lok. Not difficult to wire up in most US homes. My computer room is running from two APC Matrix 5000 5kva UPSs, which have 220v inputs and 110/220v outputs. I ran two 30A 220V (L6-30 twist-lok) circuits from the two outer poles on my breaker panel to power the UPSs, and everything (be it 110v like the regular Alphas/Suns/SGIs and such or 220v for the Crays) runs from the UPSs. Having the equipment run from dedicated 220v 2-pole breakers is very, very nice. Definitely worth the trouble. -Dave McGuire On October 31, Merle K.

RML LINK 480Z with network connection

by celigne＠tinyworld.co.uk

I've just acquired another 480Z, but this one powers up with the words "Z-NET Firmware Vers 1.1q", and there is a BNC connector on the back. Would I be right in thinking that this is a Research Machines proprietary network? The other good news is that I've got a working 5.25" disk drive with it, and a single disk, for an educational Viking game. (I thought that the machine dated from 1984, but perhaps I'm a thousand years out). Instead of typing "R" to run BASIC from ROM, you can type "B", and it boots CP/M >from disk, loads another version of BASIC, and then runs the game. I can then exit the game and use CP/M, which is something I've not done for 15 years. Oddly enough, the 480Z talks to the disk drive through the serial port. The disk drive also contains another serial port, which I've yet to experiment with. As with my other 480Z, the high resolution graphics only displays in black and white on a television. I've still not made up a monitor cable, despite asking for (and getting) the TTL RGB pinouts many months ago, so I don't know whether it will produce a colour display at all.

Computer LCD projection panels

by mrbill＠mrbill.net

I picked up a Sharp QA-25 computer LCD projection panel from a local junk shop today. The glass/"optics" look just fine (no scratches, just needs to be Windexed), but I have no manual or power supply or data cables for this. I remember using one about 10 years ago when in school, but I dont remember if this uses EGA or CGA inputs (has a 9-pin D-shell data input). I'm guessing probably CGA; anybody know specifics on the data cable? Think I can hook it via straight-9pin-cable to the CGA out port on the back of a laptop and fire it up? (fortunately I can use a standard generic wall-wart power supply; it has the specs and connector diagram on the side of the unit). Now, off to the office surplus store to get an overhead projector for $10.... Bill -- Bill Bradford mrbill(a)mrbill.net Austin, TX

old 7-segment displays

by JRichardson＠softwright.co.uk

Hi all, (not sure if I have posting access here - guess I'll find out soon enough!) The recent messages about displays have made me recall a bunch of little devices I have stashed in a box someplace... They're mounted on a board in such a way that they look like they're the display panel for an ancient fuel pump, but I could be wrong. There's two sizes, one about an inch high and the other about 3/4", and some of them are double-digit within the same housing. These things are glass, with a black background and silver segments - there's a lot of discolourment on some of them around the segments on the rear of the glass facing. Pins come out of the rear of the devices. Any ideas what these could be? Some sort of mercury vapour or something? It'd be nice to hook them up - I bought them from a car boot sale a few years ago and never got around to doing anything with them. I can probably work out which pins drive what, but have no idea what sort of voltage these things will need (I'll try to remember and get whatever text info there is on the PCB itself - think it was just a bunch of part numbers, but there might be something meaningful to someone if the board didn't just come from something as mundane as a fuel pump) cheers Jules

I saw an interesting display device at a friend's the other day, in some sort of Genrad whatsit that he was getting ready to scrap. (He's keeping the display digits though.) Each digit is a box with a bunch of tiny incandescent bulbs mounted in the back; each bulb illuminates one layer of plastic at the front; these layers are stacked and each has a digit (or other symbol, e.g. decimal point) etched in it (as a bunch of etched dots). There's a diagram on the side of each digit-box that indicates which bulb illuminates which digit or symbol. Anybody got any ideas about this thing? His speculation is that somebody didn't want to pay for nixies (but he's amazed at what these things must have cost to build in comparison), mine is that they wanted something nicer than a column of digits 0-9 with a bulb behind each. -Frank McConnell

Lisa 2/10 Dates

by fuzznut＠resspc134-189.canberra.edu.au

Hi All, I've just started following this list again after a 6month absence. Anyway, I recently picked up a very nice Lisa 2/10 in working order with all its docs/manuals/disks etc. I simply followed the advice of people on this list to "put an ad in the paper", and after a couple of goes I was rewarded with this machine. I have it currently up and running with Lisa 7/7 v3.1 and Lisa Pascal Workshop. I have one strange thing about it tho, it is a 2/10 which I thought were relased in early 1984, however the case has a manufactured date of "4282", is this a 1982 date or something else? Also, was there any 3rd party software for the Lisa available, and is there still any out there? Oh yeah, it also has a AST RAMstak card, giving it 2mb. Regards, Karl

It is a straight-thru switch. The main issue here is the colour encoding. If you could get a usable display >from your Atari in 50Hz mode, you will get a usable display from the Famicom. If your VGA/TV converter only understands NTSC colour encoding, the picture will be in black-and-white. (Assuming that it works with a 50Hz/625 line picture.) You can get analogue NTSC-to-PAL colour standard converters, which only change the colour encoding, not the number of lines per field, for about US$80 if I remember rightly; I believe MCM Electronics sell something like that. Short of making/buying a PAL-to-RGB decoder, that is what you want and would give better results more expensive standards converters. Depending on exactly which console you have, it may be possible to modify it to give true NTSC output; some Famicom clone consoles have this capability, but a real one does not. Oh, if your Famicom only has RF output, you'll need a TV tuner that is compatible with its signal. [Contact me by email if you need more help, and give a description of the console.] -- Mark

There's a diagram on the >side of each digit-box that indicates which bulb illuminates which >digit or symbol. These were common in the 60s. Driving nixies has one problem you need a transistor that can handle at least 60-80V, early transistors werent cheap (those that could). Also you needed high voltage (170-220Vdc) for nixies, plus resistors for current limiting all adding up to to a lot of space power and heat. Transistors that could switch 100ma@6V were common and cheap so the same diplay idea was used. There were other reasons with respect to readability and diplay color as well. Another config that was used is a 7segment where each segment was a wedge of plastic forming the bar and a lamp (or later led) behind it. These preceded the LED based 7 segment at low cost. For those that don't know there were also filliment based 7segment displays (have a bunch) for the early growing display market. They were aimed at the problem of good leds at that time being expensive and not terribly bright. My first freq counter has four of these and still works 27 years later. >Anybody got any ideas about this thing? His speculation is that >somebody didn't want to pay for nixies (but he's amazed at what these >things must have cost to build in comparison), mine is that they >wanted something nicer than a column of digits 0-9 with a bulb behind >each.

passive backplane wanted

by azog＠azog.org

One day I found someone throwing out an "Industrial Computer Source" SBC (look at http://www.icsadvent.com/ and search for "sb586t"). There was a passive backplane as well, but it was a 2 PCI 6 ISA slot backplane, which is kinda large. PICMG is the designation for the form factor. I searched, and found at least one company that sells a 2/1 slot backplane, but they're industrial, and wouldn't sell a single quantity. My hopes was to build a nice tiny box out of it. Given the form factor, it would be roughly the size of a shoebox. So, does anyone have a source for backplanes? I don't need any ISA slots, and would rather have just two PCI slots. I could take a dremmel to the existing backplane, but I would end up cutting off the headers for the power switch, etc, due to the way the backplane is constructed.
