Bill Gates dies and is at the pearly gates talking with Saint Peter. Saint Peter says, "Bill, you've done some wonderful things in your life and have earned the right to choose where you'll spend the rest of eternity. You can choose between Heaven or Hell, but choose wisely." Bill looks over Saint Peter's shoulder between the pearly gates and sees nothing but a lush green meadow. Deciding to heed Saint Peter's words, Bill asks if he could take a look at Hell. Saint Peter agrees and sends Bill to Hell. The Devil greets Bill at the gates of Hell and he is immediately taken aback. Much to his surprise, there's one heck of a party going on. People are dancing, the alcohol is flowing, music is non-stop and everyone is having a blast. Bill returns to Heaven to again discuss his decision with Saint Peter. He again looks over Saint Peter's shoulder and sees only a lush green meadow. Bill says to Saint Peter, "I've put a lot of thought into this decision and it may sound foolish, but I'd like to spend the rest of eternity in Hell." Saint Peter fulfills Bill's request and returns him to Hell. When Bill gets back to Hell there's been a big change. People are writhing in agony, flames are burning, moans of pain and despair are everywhere. Bill, being quite shocked at the sight asks the Devil, "What happened?? I was just down here a little while ago and everyone was having a great time!" The Devil says, "Oh that... That was just the demo!"

20mA cabling questions

by truthanl＠oclc.org

Ethan, The 20 ma current loop is not always 12 Volt loops - its 20 ma Loops. I have the IBM tech ref for the IBM PC Asynch Port which shows one Cuurent Loop interface implemented on 25 pin D-shell pins 9,11, 18 & 25. (Only when an option jumper block selects current loop.) For Xmit they have 8250 (ttl) S-OUT buffered through an LS125. The LS125 output "fans out" feeding both the RS-232 driver as well as three 7406 inverters in parallel for "ample" 20ma drive. In series beyond the three || 7406 inverters is a 100 ohm resistor routed to pin 11 labelled " - xmit CL out". Pin 9 labelled "+ xmit CL ret" is pulled high to 5V through a 49.9 Ohm resistor. For RX they show an opto coupler, a 20 ma diode anode tied to pin 18 labelled "+ RCV CL data. Its cathode is tied to pin 25, labelled "-RCV CL ret". The switching transistor of the opto coupler drives the input (Low)on an LS04 inverter which is routed through jumper selection to "serial in" (SIN)on the 8250. So you need to determine if your third CL pair drives, or reads, the "reader" relays. Each pair is either a source or a sink for current. Another good source for reference on computer controls interfacing is a Burr- Brown publication called "The Handbook of Personal Computer Instrumentation" I have a spare Fourth edition Published in 1989. Stop by OCLC and pick it up. Sincerely Larry Truthan -----Original Message----- From: Ethan Dicks [mailto:ethan_dicks@yahoo.com] Sent: Wednesday, December 15, 1999 2:03 AM To: Discussion re-collecting of classic computers Subject: 20mA cabling questions The PDP-8/L restoration continues. I have two devices to attach to my -8/L for testing - a VT220 (all have 20mA current-loop connectors) and an ASR-33. One problem: the connector on the VT220 is female and the cable coming from the ASR-33 is male. While this might not seem like a problem, it becomes one when I have to use either device from the same W076 card. Many years ago, I rigged up a working *male* cable from a W076 card for use with this VT220. It still works. I have a quick-n-dirty Switch Register->TTY test program and can emit all sorts of ASCII characters for testing. When I stick a different W076 card in the -8/L, one with a female connector, within the limitations of this particular ASR-33, all is well (the type cylinder doesn't always retract all the way, nor does the hammer always return to the proper position, but I currently suspect that the replacement rubber pad I have attached to the lever arm/hammer does not have the correct resiliency). So... my first goal is to come up with some cables that will solve my W076 problem. Is there a good 20mA primer out there? I have a basic understanding that it's all based on 12VDC loops, send and receive take four wires, but there are six coming out of the W076 card... the extra two are reader-run relay signals, obviously not needed for a VT220, but very important for the ASR-33. A) Is there a color standard for the 20mA connector cabling? I have three W076 cards with three different arrangements. B) When I make a pin-one-to-pin-one male-to-male 20mA cable, it does *not* work with the female-equipped W076 and the VT220. A few moments with a DVM show that the arrangement of a W076 and my straight-through cable do not match the pinout of my long-ago-homemade W076-to-male connector that does work with the VT220. Is there a special wiring trick for male-to-male 20mA cables? C) Somewhere, I have a small box of 20mA cables that have, IIRC, four conductors. Presumably, these are for VT52s. I have no reason to expect that they won't work with the VT220, once I find them. I take it, then, that in the "old days", one never used an ASR-33 as a tape input device except on the console interface? I'm thinking of some of the ancient distribution panels for other DEC serial cards that had EIA (RS-232) _or_ current-loop connectors. Am I missing something? Right now, because my TTY print mechanism is acting up (must press down on the type cylinder between chars, and the line-feed mechanism sticks 20% of the time) I have been testing by inserting one W076 in the backplane for paper tape reads and the other W076 in the backplane for interactive testing. Obviously, this can't go on forever. I suppose I could rig up a *really* bizarre cable that sends the output to the VT220 and takes input from the TTY. Maybe I'll just work that angle. It would save on paper. I don't have much cause to punch stuff right now, and until I get the primary box working I won't even attempt to attach my outboard 8Kw to this CPU (the eventual goal of all of this is to set up for 8K-papertape-BASIC and play Star Trek. I have all the tapes to do this, but I do have to replace the floating-point tape that tore the last time I loaded it (a long, sliver of a tear, not a perpendicular, parting tear). I still know next to nothing about the pr/s01 except that it is *not* 110 baud. Another one of my ancient projects is to replace the M452 variable clock module with a home-made digital baudrate generator. I suppose I'd have to wire a switch on the backplane as well to select the M706/M707 from two stop bits to one when the baud rate was 150 or higher, but I have a prototype module and I have the COM 8116 clock chip and I have the proper crystal to drive it. What remains (besides sitting down and finally *making* it) is to decide if I want to build in the ability to drive transmit and receive at different rates as was common with VT52s. I could receive at 150 or 300 baud and transmit as fast as possible, perhaps 9600 (I'd have to look into the M706/M707 designs to even hazard a guess, but even 150/2400 is an improvement). The goal would be to be able to use the pr/s01 with a TTL -8. -ethan ===== Infinet has been sold. The domain is going away in February.

serial console on VAXstation II/GPX? And backup question.

by eric＠brouhaha.com

I'm probably overlooking something terribly obvious, but is there some way to make a VAXstation II/GPX use the console SLU rather than the VCB02 graphics system, short of pulling the VCB02 cards? And if I do that, will VMS also use the SLU for the console? I'd like to make an image backup of the RD54 in the machine, since I need to wipe it to install NetBSD. Does anyone have any suggestions about the best way to go about that? AFAIK the TK50 drive in the machine probably works, and I do have some tapes. I could probably fumble my way through making some sort of backup, but then I wouldn't know how to restore it later. Or, if anyone has a spare RD54, then I wouldn't *need* to wipe the disk. :-) Thanks! Eric

Qbus slot ordering?

by CLASSICCMP＠trailing-edge.com

>Does anyone know if the CONFIGURE command in the VAX prom suggests slot >ordering in its output? No, it doesn't. The order of CSR's doesn't have any bearing with what cards go where in the backplane. The order of cards in the backplane will depend on interrupt and DMA priority. Generally, peripherals that *will* lose data if they can't get serviced in time get put closest to the CPU. Examples here are serial lines, etc. Next come peripherals that will have to do a retry if they don't get serviced in time, but they will be able to do a retry. Tape drives, for example, might come here. Finally come devices where there's no real penalty for a retry, and maybe the peripheral doesn't care at all if the CPU takes its own sweet time in dealing with it. Something like a real-time clock would come in this category. >I ask because I'm trying to configure my uVAX with an additional 4 serial >lines using either a DHV11 (get an extra 4) or a DZV11.

They're largely historical; the DZV11 is based on the DZ11, which is an "old-time" async multiplexer, and comes early in the autoconfigure rules. The DHV11 came many years later, and comes much later in the autoconfigure rules. If you're interested in knowing where the autoconfigure rules come from and how they're applied, take a look at Alan Frisbie's DECUS presentation at http://metalab.unc.edu/pub/academic/computer-science/history/pdp-11/hardwar… -- Tim Shoppa Email: shoppa(a)trailing-edge.com Trailing Edge Technology WWW: http://www.trailing-edge.com/ 7328 Bradley Blvd Voice: 301-767-5917 Bethesda, MD, USA 20817 Fax: 301-767-5927

DTC 520A - SASI or SCSI?

by edick＠idcomm.com

I'm currently the victim of severe abuse from the significant other . . . she's insisted I put my toys away . . . In the process, I just an hour or so ago had the manual for this controller series in my hands. Having looked at both the manuals, 510 and 520, I find mention of neither SASI nor SCSI. The signal definition seems to track SCSI except for pin 42 which they call TDN, which is a new one on me. The manual doesn't seem to define this signal. Maybe its TBD??? The board supports parity, which, IIRC, SASI didn't. It supports both floppy and hard disks of the 5-1/4" flavor, with MFM on the HD and either FM or MFM on the floppy. It's late and I'm too pooped to sit down and scan the approximately 25 pages of manual for you, particularly since the PC with the scanner is in pieces for transit to the basement. I'll see about getting it scanned in the next few days, but keep in mind it's a really poor Xerox copy, some lines of text in several places being completely illegible. The fact that I have these manuals suggests that DTC was a major competitor in the bridge-controller market, else I'd have probably ignored them. For the last couple of weeks I've been kicking the SCSI vs. SASI thing around with Don Maslin and Allison Parent in the Ampro Little Board context, and, as Allison clearly pointed out to me, the SCSI drivers Ampro provided seems to operate a few of the garden-variety SASI controllers just fine. I'd conclude from my observations in going through AMPRO's code and from Allison's comments, that the hardware differences are probably irrelevant in the early-'80's context. Some controllers have a software reset, but not all, and since you have to option of doing a hardware reset, I guess that won't be missed. They didn't have a standard "common command set" back then, so you'll have to commune with your muse to devise a driver. I have had absolutely no luck with the various ADAPTEC, OMTI, and XEBEC bridges I have in conjunction with a PC-based controller. Other things I've found in the current spelunking expedition: Tarbell S-100 FDC (1771) manual XCOMP manual for ST-R bridge controller to HDD CompuPro Econoram SRAM Board manual (model??? ... 16K of 2147's) CDC 6000-series Assembler (COMPASS) manuals for SCOPE OS.

Hewlett Packard 3265 question

by SeaMasterZ＠aol.com

Hi I realize this is for older computers but I have a question concerning a newer computer ... I have a HP Pavilion with win 95 and a "suspend" feature ... the computer is very sensitive to mouse movement, which "wakes the computer up" ... is there a way to have the Suspend feature be interrupted only by a keyboard entry, basically turning the mouse movement feature off? I don't want to abuse the list, but this is really a pain, sometimes I find myself away for a while inadvertently, and the computer is grinding away ... also, should an idle computer have massive amounts of drive activity? I have powertools for AOL and AOL on, and the drive can suddenly spend 5 minutes grinding away, no apparent reason ... system resources drop into the 30's and 20's which make me wonder about a virus but Dr Solomon came up clean. Thanks for any info Ray Cook SeaMasterZ(a)AOL.COM PS - Right now I have Microsoft Word, Netscape AOL and Powertools open, and the system resources are at 26% ... with 64 MB of SDRAM, is this normal?

IBM 4216-020 printers?

by mrbill＠mrbill.net

Anybody know anything about these? I just picked up six of them for $25 , with two fuser units and no toner carts, and a "4216 Personal Pageprinter Technical Reference". Five of the printers have a strange 15-pin D-sub connector that resembles an AUI or PC joystick port, with a set of DIP switches beside it. The sixth has normal serial/parallel interface connectors. None of these printers have ever been used; some are still in the original plastic "bag" wrappings. They date from around 1988. My question is - whats the strange 15-pin interface, and do I have any chance of hooking it to a PC or similar machine ? I got these so cheap because the guy who had them was going to toss them, and I hate to see stuff get tossed. Hopefully they'll turn into something useful. Thanks.

Mini-history of '@'

by jfoust＠threedee.com

================================================================ BOB METCALFE: "From the Ether" InfoWorld.com December 14, 1999 ================================================================ OPEN-SOURCE SENDMAIL WELCOMES ITS COMMERCIAL COUSIN, SENDMAIL INC. LET'S START this week with some "open source" operating systems history. This will bring us from last week's letter of the week, lambda, to this week's, atsign (@). Then let's check on how open-source sendmail software, which uses atsign, is being leveraged by modern capitalists at Sendmail Inc. Now look, we had open-source computer operating systems in the 1970s. They included MIT's Multics, MIT's Incompatible Timesharing System (ITS), Bolt Beranek and Newman's Tenex, and AT&T's Unix. For example, we ran Tenex at the Xerox Palo Alto Research Center on our two clones of Digital Equipment Corporation PDP-10 minicomputers. But when minicomputers took off in the 1980s, it wasn't Multics, ITS, Tenex, or Unix that won out by freely proliferating their sources. Modern capitalists at Digital won in minicomputers by selling binaries of their proprietary VMS operating system, developed by the same David Cutler soon to deliver binaries of Windows 2000 from Microsoft. If you're an old programmer, you probably used atsign (@) back then to indicate indirect addressing in assembly languages. You wrote @1234 to tell your computer not to use 1234 as an operand address, but rather to use the address found in location 1234. I wrote a lot of PDP-10 atsigns in my day, and so did one Ray Tomlinson, who was working with Tenex in 1970 on early versions of Internet host software. Tomlinson wrote the Tenex software that composed, delivered, and read the first Internet e-mail. He doesn't remember what the first e-mail said, but we all remember what ASCII character Tomlinson chose to separate his e-mail address from the name of the server where his mailbox was kept. He chose atsign (@). Ray@BBN meant Ray at BBN. Over the next decade, name and mail protocols changed, but atsign persisted. And one Eric Allman led the development of sendmail, to this day the Internet's primary (75 percent) mail server software.

Qbus slot ordering?

8" drives and Compaticard / Uniform

by edick＠idcomm.com

If the situation with the TANDON slimlines is any hint at this I'd say it will only confuse one to look at the '801 spec to decide how to jumper an ;860. I'm milling around in the basement today, and will probably find the SHUGART spec's I have, including the jumpeing info for the ;860. It's just a matter of time. I have to find a place to put the stuff I've brought upstairs . . . <sigh> . . . so my significant other can put up holiday decorations. I was raised by the Grinch himself and will probably never learn to enjoy Christmas except (MAYBE) for the period between Dec 24 and Jan12 (Epiphany) which was, in my one-time homeland, Germany, the traditional extent of that particular celebration. I'd vote for anihilation of any person place or thing making even an oblique reference to that celebration outside the time windown in which it belongs. I'm usually holiday'ed out by the tenth of November . . .

8" drives and Compaticard / Uniform

by edick＠idcomm.com

Aside from removing one of the 8" drives from the daisy-chain, the only thing I can recommend is to look very carefully at the way in which each signal is used on the cable. My own recollection of the cabling details as applicable to 8" drives is that the Compaticard really doesn't want you to have more than one of them. That, in fact, is the reason why I owned one for ten years and didn't use it. If you look at the combination of signals used on the CompatiCard and then look at how the various drive types will interpret them, that should help you to understand how the card is selecting the "wrong" drive. As far as jumpering your drives, I'd suggest you use the most restrictive set of qualifiers that you can come up with, in order to avoid ambiguous selects. The PC software is geared to using the signals on the cable in a "strange" way due to the cute fix they (IBM) thought up for their internaly twisted cable. IIRC, the cable was twisted such that each drive will see the "motor on" signal as DS1 (based on numbering from 0) . The '860's have a "motor-on" signal as well, though it shouldn't be used as it is in the PC-style environment. The drives need to be set up such that their activity LED only comes on when the drive is selected AND ready. That way, you will have an external indicator that the READY signal is valid on the cable. The PC doesn't use this as a ready, since some mini-drives don't generate it correctly, but it may help you to see what's actually going on. I don't suggest that you change the jumpering on the 5-1/4 or 3-1/2" drives because they tend to vary too much. If they work, that's enough to contend with for now.

Info on Canadian S-100 Computer

by donm＠cts.com

I have an inquiry from a chap who purchased an Exceltronics S-100 kit, a Canadian make, in about 1982. He still has the machine and would like to resurrect it, but has lost the system disk over the years. Does anyone have any information on this critter or, better yet, a system disk for it? Thanks. - don

8" drives and Compaticard / Uniform

by edick＠idcomm.com

I'm not as "into" the CompatiCard, which, by the way, I just recently sold for a pretty good price, as I might be, but I do recall that there was jumpering information in the manual. What you nave to do is figure out what the equivalent jumpering for an SA850 would have been. I don't think there was 850-specific information, but as I recall, the manual didn't suggest one could use more than one 8" drive, either. There's information on the MicroSolutions web site, as I'm told. Perhaps they can help you. regards, Dick -----Original Message----- From: Bob Stek <bobstek(a)ix.netcom.com> To: Discussion re-collecting of classic computers <classiccmp(a)u.washington.edu> Date: Monday, December 13, 1999 5:43 PM Subject: 8" drives and Compaticard / Uniform >Dick (or anyone else) - > >Would you have the jumper settings (default positions, definitions, etc.) >for a Shugart 860?

Hewlett Packard A2094 Monitor (Standard RGB ?)

by edick＠idcomm.com

Worse yet, they were rewarded! What was really crazy was that I could do all the stuff I needed done on my desktop PC, but the department madated that the HP system be used, which meant that although my design was complete and the boards sent out for wirewrap and returned, tested, etc, while the first-level simulations are still (well the project was cut short ...) in day-for-day slip (for over 10 years now) because HP's simulation model libraries used the same filenames, yet their content was mixed, i.e. different simulation timing resolutions, etc. They had no models for currrent generation (then) parts, so each component had to be ordered separately at HUGE cost. In the time it took the thing to simuate a single flip-flop, I could walk the considerable distance to my office, start up my PC-XT, ( I had to bring my own because the company preferred MAC's, for which no useful software existed) load the software and the files and run and subsequently print my simulation, and still had time to walk back to my diligently running $50K workstation and drink a cup of coffee waiting for it to finish the simulation. A typical simulation that took 20 seocnds on my PC-XT took 15-30 minutes on the HP, and that was only in the rare instance when everything worked. During the year that these guys made their trade study, they didn't consider machines from Mentor, Daisy, or Cadnetix, which were the three leaders in the industry at the time. In fact, neither of them had even heard of those three. Now, I think they should have been fired, not paid multiple tens of K-bucks in "performance awards" for this boondoggle.

Assembly docs for Zenith/Heathkit Z-150 PC compatible ??

by cfandt＠netsync.net

Upon the date 01:17 PM 12/13/99 -0600, Kevin L. Anderson said something like: >I have my original Zenith (ZDS) Z-150 computer, which was their >answer to the IBM 8088/86 PC. This was also offered as a kit >from Heathkit (as the H-150?) in the mid-1980s. > >My Z-150 currently won't start up, with lights stopping in the BIOS PROM >startup sequence. Does anyone have the equivalent Heathkit assembly >manual(s) and drawings for this system? Or are there similar systems >around that board swapping might be possible? Hi Kevin, I don't have technical manuals for the 150's like I do for my earlier 8-bit Heath machines (H-8 & H-89). Perhaps another listmember has one to refer to (Tony?). Chips were socketed on these machines so try carefully pressing them into their sockets in case there is an intermittent connection causing the problem. Place the board onto an antistatic bag upon a firm padded surface which will help you do this. What's the status of those lights (the LEDs on the CPU board)? Have an Operating Manual? I think I recall something about interpreting the LEDs in that book. I've got one somewhere up in the library. I've got a big heap of 150's down in the back garage which I am planning to: (A) Hammer together working systems and maybe sell for cheeeeep, (B) provide parts for folks like you, or (C) scrap that which is not desired/useable. Methinks (C) is the ultimate fate of most of the pile nowadays, (A) is somewhat folly, butcha never know ;-) Seems item (B) is just for you. Email me. I think there's at least 15 Z-150 boxen I've got -all from work when we moved up to 386/486 and later machines.

Greetings, I just picked up a PDP 11/23 in excellent condition from an accountant that was going to dispose of it. It has two RL02 drives and 10 disk packs. My background in DEC stuff is only VMS, so I checked around and found some info on booting the machine, which I did successfully.. once. I was able to get a directory listing and type a few files. The system has RT-11 v4.00 with a runtime package in Dibol for general ledger, etc. I halted the machine and tried to restart it again, only this time it complains. The display I'm getting is.. TESTING MEMORY 0124.KW START? Y 000010 @ I also tried 173000G at the @ prompt, and still get 000010. Is there something I'm doing wrong here? I've also been searching for a FAQ of some type on RT-11 and the 11/23. Found some stuff, but would be very interested if someone has a jewel URL they'd be willing to share. Like I said, the machine is in beautiful shape, been well cared for, one owner. I had to drive 5 hours one way to get it (Houston to Shreveport, LA), but was worth every mile. Any help would be greatly appreciated! Best regards, Mark Honeycutt Baytown, TX

11/44 - RSTS Fun

by jpl15＠netcom.com

Today when I got up I knew it was going to be 'play with big computers' day... I got 24 of the 36 ports up and running on my 11/44 machine... it only took four or five hours of messing around with things. I made good use of the RSTS "Broadcast" untility, and by repeatedly sending long messages to all ports, I was able to work out the loose/upside down cables, DCE/DTE confusions, etc. Thank Heaven for the little RS-232 breakout box and status indicator. I had the console on my PC, a C.Itoh C101 on another port running the DISPLY system status monitor, and an LA120 on yet another port. Even the Kennedy 9100 woke up happy and functioned well. I just shut the system down (after listening to the wonderful roar for about eight hours) and now it's time to run SHUTUP on myself. Nothing like having the OS Docs, either. I certainly learned another big chunk of RSTS/E tonite. More than half the battle was understanding how to manage and configure the system. It took a great deal of study and cross-referencing to find the little secrets and gotchas. I am in the market for a Unibus Ethernet card: will beg/trade/buy. Anyone have such a beast? Now it's time for the 11/44 to talk to the uVax II. Next task is getting one of the old DC03 Modems hooked up and running... then to load a comm program and access this List from a completely vintage PDP system. At 300 Baud. [Woo,Hoo] Cheers John

Hewlett Packard A2094 Monitor (Standard RGB ?)

by edick＠idcomm.com

It might be well to consider that the place that had these HP units and still has the monitors, is a retailer of surplus electronics. What's more, he's located in the Denver metro area. Almost all this stuff came from Martin Marietta from the period when they were disposing of lots of hardware prior to being bought up by Lockheed. The fact that they were prone to BUY this kind of stuff is one of many examples available of the type of behavior which put them in the position to be taken over by Lockheed. This HP stuff never worked properly during the time I was there. It was mostly software trouble, but it never did work well enough that I was able to use it without having to use my PC to do the "real" work. HP got into CAE in '88 when they bought Apollo, and announced it was getting out in '91, leaving everyone who'd bought their hardware/software in the lurch. Meanwhile, Martin promoted and/or paid bonuses to the fools who had bought in to the previously unheard-of and inexperienced CAE/CAD vendor HP turned out to be.

NCR 400 UPDATE

by steverob＠hotoffice.com

Well, I went and picked up the NCR Tower 400 this weekend. The 400 is about the size of a LARGE tower PC. I haven't measured but, it's about 28" inches tall, 24 inches deep, and 7 inches wide. I'd guess it weighs about 75 pounds. As with all new aquisitions, the first thing I did was open it up, remove all the cards, blow out the dust, check for missing or damaged parts, and then reinstall everything. The 400 is a 20MHZ 68020 machine built on a 4-slot multibus backplane. This particular system has 20MB of main memory, 60MB tape drive, 120MB hard drive, 10 serial ports, 2 SCSI interfaces, and 2 serail printer ports (each port will support 4 printers). Based on the date codes on the chips, this machine was probably built in late 1985. I reassembled the system and spent HOURS trying to get it to talk to a terminal. The system has a funky 15 pin connectior for the console and no documentation. I had to trace the connections back to the CPU and was able to determine which were inputs and which were outputs based on whether they went to a 1488 or 1489. After much tinkering, I was finally able to get the system to send data to the terminal during boot. NOTE: It uses a 9600 baud, 7-bit, and no parity. Spent another 3 or 4 hours and was finally able to get the terminal to talk to the system. Whoopee!!! Finally got data going both ways. Unfortunately, the system still won't boot the OS. The sequence goes something like this: ? ? MMU MEM HIO1 HIO2 DK5 The system hangs at the DK5 message. Since I'm not seeing any disk activity, I'm sorta assuming the "DK5" refers to a disk activity. If anyone can confirm this, I'd appreciate it? It isn't a big deal because I'll be getting the 450 in a few weeks and if the 400 doesn't work, I'll have a few spares for the 450. I got a look at the 450 while I was there and it looks more interesting. Physically, it about twice as "thick" as the 400 and probably weighs twice as much. Didn't look inside but would assume it has a 6 or 8 slot multibus backplane. I believe it will support 16 terminals. The good news is that the 450 is still in daily use so, I know it'll work when I get it home. The system will be available in a couple of months and I'll send an update once I get it. Neither machine is really all THAT interesting but, I don't have any other multibus systems and kinda wanted one. Later, Steve Robertson - <steverob(a)hotoffice.com>

Assembly docs for Zenith/Heathkit Z-150 PC compatible ??

by kla＠helios.augustana.edu

I have my original Zenith (ZDS) Z-150 computer, which was their answer to the IBM 8088/86 PC. This was also offered as a kit >from Heathkit (as the H-150?) in the mid-1980s. My Z-150 currently won't start up, with lights stopping in the BIOS PROM startup sequence. Does anyone have the equivalent Heathkit assembly manual(s) and drawings for this system? Or are there similar systems around that board swapping might be possible? What is somewhat unique about the Z-150 is that there is no motherboard as such (unlike all the PCs and Wintel systems), just an ISA bus and the CPU on its own board. A idea similar to mini- and bigger computers, but alas, except for the a few exceptions such as S-100 systems and the Apple-II, an approach that never caught on in the so-called "PC" series that have dominated since the mid-1980s.... Just curious. Thanks. Regards, Kevin Anderson * * * * * * * * * * * * * * * * * * * * * * * * * * * * * * * * * Kevin L.

Tripos on the PDP-11

by healyzh＠aracnet.com

I was just looking up some info in the PDP-11 FAQ, and glancing through the list of OS's, I noticed Tripos. Does anyone have any information on what models it ran on?

Qbus and Q/CD jumpers

by cmcmanis＠mcmanis.com

I've read the micronotes but I'm still confused. I've got a DHV11 in a BA213 which is 12 Q/CD slots. Since the slots aren't Q/Q it doesn't need the jumpers installed for the grants but will having them installed screw anything up? --Chuck

Northstar CPU Card in Regular S100 Bus?

That should certainly be the case with the N* CPU I recently gave to one of the list participants. It had no hardware on board which would prevent it >from working with pretty much any other S-100 hardware, aside from the usual risk, since there were no real standards, even after the adoption of the IEEE P696 standard. With more signals than were needed, it was always possible another maker's card might expect different combinations of signals to do the same job.

Weekend finds - uVAX II w/ SCSI!

by cmcmanis＠mcmanis.com

This weekend I saved most of a uVAX II from the scrapper. It is a configuration I didn't recognize with two BA23's. One "normal BA23 and then a Q22 jumper into a second BA23. The rack "sleeves" were connected across the back with a hinged door that held all the cabinet hardware. Pretty neat. Anyway, in what was a total shock, the thing has a "Transitional Technology Inc, QTD-1" Q-bus SCSI controller! If this thing works I'll be in heaven since I've yet to get a working SCSI disk controller for my Vaxen. This looks kind of like a Viking controller, except it has several key (and hopefully really good) differences: 1) It has a 10 pin header that looks like the DEC standard DLV-11 type serial port (rather than the viking "in the scsi cable" port.) 2) It has an NCR53C90 SCSI interface, and 18 nat'l semi 75176BN chips wired up to the 50 pin connector. (I'm hoping these are differential drivers for FAST SCSI II drives) 3) Then it has a Motorola M68901 a covered 40 pin chip (probably the processor) and one RCA 6264 ram chip and a 27C256 EPROM with the "1.7a" firmware in it. Has anyone used one of these? Do you have docs on it? Would you be willing to FAX me the setup information? (I've got a 9GB SCSI drive just waiting for this type of information :-) Other interesting bits was the KA630 + 2 8MB memory boards (M7609), a DHV-11, an M8020 SLU, and an SDI controller (two board set.) The BA23's suffered some damage when they were ripped from the rack (which I didn't save) but there seems to be a salvagable TK50 in one of them and a Q/Q backplane. (The second BA23 was all Q/Q slots! --Chuck

Good Week

by jrkeys＠concentric.net

Well this week has been a good one in that I picked up a very large number of manuals for all types of hardware and software from Kim-1's to early Packard Bells. I got over 20 - 2600 cartridges plus 10 for the Vectrex. I also added over 15 new mousepads to the collection. I got a NEC StarLet portable computer model PC-8401A that needs work. An HP Integral PC with a HP 82916A 1mb memory module, a HP 82919A option 001 Serial interface module, HP Rom Module UX/RO Rel 5.0 unit turns on both nothing on the screen. I picked up a Tektronic type 576 Curve Tracer that needs work. I also got a Commodore 1351 mouse and an Amiga mouse at the same thrift. I go 3 notebooks that are not 10 years old yet but they were free (1-286 & 2-386's). I also got for free a Sears TV/Monitor from June 1984 that still works. All in all the week was very good for saving items and building more for the museum.

Need a PDP-11/34 operators panel?

by jimw＠agora.rdrop.com

...or two? Trying (yet again, or is that still?) to make some room on the 'Garage' for winter projects, and came across a couple of potentially interesting things which could use a home... Two PDP-11/34 operator panels. These are NOT the panels with the numeric displays and keypad. These panels have three LED status indicators, two switches (boot/init & run/halt), and a power selection dial. I don't recall where/when I picked them up, and my '34 has it's panel, so... If you have a machine that needs a panel, you can have one for the cost of shipping. (unless you feel real guilty and want to throw in something for trade) If you just want to hang it on the wall, it'll cost you $25.00/ea or an interesting (and useful) trade. -jim --- jimw(a)computergarage.org || jimw(a)agora.rdrop.com The Computer Garage - http://www.computergarage.org Computer Garage Fax - (503) 646-0174

Those which are completely passive only work on certain dual-function mice, in which the PIC can detect the change -- by detecting the voltage on a different pin -- and act accordingly, changing the protocol. In general, you can't turn any old serial mouse into a PS/2 mouse, nor vice-versa. To further confuse, there are at least two pinouts for such adapters. However, there are some active adapters, which themselves contain a processor (usually a PIC) which will convert the serial protocol into PS/2 protocol. -- Pete Peter Turnbull Dept. of Computer Science University of York

Weekend Classic Trip Report

by wirehead＠retrocomputing.com

Just wanted to let folks know the results of my Saturday trip. I left Des Moines and drove to Kansas City, where I met Mike McFadden. Mike's an extremely pleasant, helpful fellow who showed me where to find good surplus in KCMO. I'll DEFINITELY be visiting KC more often! I went there to pick up the VT220s he advertised on ClassicCmp. I walked away from one surplus place, having spent only $10, and got (1) M7606 MicroVaxII CPU board (spare for my MVAX II) (1) Cisco IGS Multiprotocol Router/Bridge and a couple miscellaneous bits and pieces. Not bad for $10. Then I drove to Lincoln, NE and visited Bill Richman, who recently posted some items for auction. Another really nice guy. Picked up the Tek 532 and the aluminum cart it sits in. I also picked up some other spiffy items, which I'll describe later. So, the entire trip (including gas) cost me $90 (less than the cost to ship the items), got me out on the road for a few hours of relaxing driving and allowed me to bring home some unusual items that are scarce or non-existent in Des Moines.

Hewlett Packard A2094 Monitor (Standard RGB ?)

by edick＠idcomm.com

Be careful, now! Don't agree to sell the monitor "cheap" if that means throwing good money after bad. My experience with persons wishing to buy something "cheap" means it is supposed to cost them less than it costs you. Here you're asked to risk paying $160 for a $50 video card with what apparently amounts to a customized EPROM. I'd not buy one of these unless you can, at a minimum, (a) return the card if it doesn't work as you expect, (2) ship the monitor to someone elese who wants it with advance payment in the amount of your purchase PLUS the cost of freight, which will be MUCH more than you pay the monitor. The packing task will be enough of a pain that no one should complain about paying these costs. My experience has been that collectors of old hardware won't pay these actual costs routinely, though they might if the item in question is relevant to a specific project in progress. Good luck!

Hewlett Packard A2094 Monitor (Standard RGB ?)

by musicman38＠mindspring.com

I have come to the conclusion that its to costly to use the HP A2094 monitor on my PC, I can purchase a nice 17 inch Monitor at about the same cost to get a special video card which will never be fully compatible with all my applications. However I just realized that this monitor was possibly intended for the HP Apollo 400 workstation that I got at the same warehouse. Can anybody verify this ? Also there was several HP 20 inch mono monitors ready to be tossed in the dumpster, I thought these were Composite video inout because they had one BNC connector on them, but likely some sort of fixed Frequency input..

Hewlett Packard A2094 Monitor (Standard RGB ?)

by musicman38＠mindspring.com

>There are special video cards that can support a fixed frequency monitor >even in text modes, but I'm told that they cost about $200. Thanks everyone for the great information. I have now found a Fixed Frequency VGA Card that supports all Fixed Freq monitors for $139 to $159 in PCI or AGP.. http://www.si87.com/Products/Videocards/saturngl.html This would resolve any problems using this monitor. But the big question now, is this monitor really worth the cost of a new Video Card ? Or does it make more sense to just buy a new monitor ? Good Points: 1. Its a Big 19 inch monitor.. 2. It has an aperture grille, used in high end Sony type monitors. 3. Its an HP monitor its clean and no screen burn. 4. According to specs this monitor will support 3D graphics directly with the right video card. 5. According to Specs it supports an impressive 1158 X 870 resolution. 6. Seems like I get a good working 19 monitor for only $160.00 Negative Points: 1. Its 6 years old. 2. Don;t know how many hours are on it. 3. History is unknown.. 4. The Sucker is Big and weighs a ton.. So Should I do this or Not ? Phil...

FS: VMS 6.2 Distro & Docs

by kyrrin＠bluefeathertech.com

This is being CC'd to both port-vax and the CLASSICCMP lists. I have available a complete (and I do mean complete -- I've even got license PAKs!) distro set for VMS/VAX 6.2 on CD-ROM. This has not only the VMS install, but also a whole blortload of extra software from the 'Consolidated Software Distribution' kit. There's about 12-13 CD's total. Want more? How about a complete documentation set, also for VMS 6.2. This is the new DEC 'White Wall' (paperbacks in those goofy boxes), and I remember taking them out of their shrink wrap so I'm pretty sure everything's there. All the stuff could be shipped, but the books will make it heavy. I guesstimate a minimum of 30 pounds (conservative). I'm open for offers. Best offer with the earliest timestamp on the reply gets it. Be ready to cover shipping as well if you're not local (Kent, WA, southeast of Seattle). Thanks in advance. -=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=- Bruce Lane, Owner and head honcho, Blue Feather Technologies http://www.bluefeathertech.com // E-mail: kyrrin(a)bluefeathertech.com Amateur Radio: WD6EOS since Dec.

Hewlett Packard A2094 Monitor (Standard RGB ?)

by edick＠idcomm.com

You can verify this yourself by visiting the HP web site. HP bought APOLLO in '88-'89 or thereabouts. Those HP workstations that have been selling around here for about $25 work with a similar monitor though I'm not certain whether it's exactly the same number. The fellow who's got them gets $25 per workstation/server and $25 per monitor. I think he's sold only one of these monitors (to me) this past year. $5 would better reflect their relative usefulness.

There were others who worked on the projects, too.

Can you see the core mats or is there an opaque cover? I have some stuff that may be the same thing you have (from an 11/05). Mine is marked similarly, but three of the mats are blank. I suspect that the same PCB could be used in several machines, including an 18-bit machine w/parity, depending on how many mats were wired. -ethan ===== Infinet has been sold.

Motorola 68k family ( was Re: Comparison of system specs. )

by ndiablo＠diablonet.net

Well, I can't say much from the Amiga side, but after playing around with Macs for a number of years, I don't think there were really any instances where instructions were _removed_ that broke software... I do remember there were a few specific issues when features were _added_ and a lot of software broke, like when the 68020 macs were introduced with onboard caches that broke some software that used self-modifying code, and when the 68040 was introduced with its onboard caches, I think it ended up breaking some software as well. This is all mac-related stuff, though, so I don't know if there were ever any similar issues over on the Amiga side. -Sean Caron (root(a)diablonet.net)

M865/M833 questions (and serial cable info)

by ethan_dicks＠yahoo.com

In re-reading the PDP08 FAQs, I came across a mention that the older KK8E cards (three digit handle numbers) are somehow "broken". Can anyone elaborate? I have a couple of KK8E sets, one with the M833 timing module and M865 20mA- only TTY interface. What might be odd about them? I need to be able to use the M865 as I only have one M8650 KL8J interface (with two cables - one EIA and one 20mA, but the 20mA cable is missing the Berg housing - it's a bundle of loose connector pins on the interface end). Speaking of cables, I was attempting to build a new cable for my PDP-8/a and re-discovered a minor detail - the DKC8AA has this interesting feature - the EIA input and the TTL input to the serial hardware are not connected at the board level. There is this loopback wire that must be installed on the Berg connector to get the input data into the hardware. I remembered this after much frustration from the days when I used to get discarded cables from my former employer who made sync serial hardware. We shipped a nearly-fully- compatible cable with each and every one of our boards. All I need to do to convert these to PDP-8/a use is to add that jumper wire. If anyone is in need of a Berg-to-DB25 cable, let me know. I have a box of them that can be converted to PDP-8 use (for a nominal fee, of course ;-) -ethan ===== Infinet has been sold.

We got any 68k pro's around > here? For all practical purposes, the differences with the 68000 and the '40 (and higher) are more related to priv'ed instructions, not missing instructions. There may be some missing ones, but they are not ones that were well used (BCD packing and unpacking instructions come to mind, but I'm not 100% sure of that). Cache and timing issues for instruction-set-dependeng loops are much more of a problem. Because the 68K family didn't change as massively as the Intel x86 family, programmers tended to use cycle-counting loops more often than they should. Who here remembers the first generation of VGA games that didn't run right on the 486 because the loops were running too fast? DOS programmers learned their lesson years ago when poorly-written software broke with every new hardware design. Such things came more slowly to the Motorola world. The first compatibility problem came with the 68010 and the MOVEcc instruction. It's unpriv'ed on the 68000, and priv'ed on the 68010 and up. AmigaDOS provides a call to extract the relevant condition bits that one is supposed to use. The practical solution was to install an exception trap to handle when some errant programmer used the forbidden instruction and emulate the real thing. It's much, much slower, but it's the kind of thing that doesn't get executed in a loop, so wall-time execution speed is essentially unaffected. For the trivial-minded, the AmigaDOS calculator that came with AmigaDOS 1.1 uses the offending instruction and makes a good test that the exception handler is installed. -ethan ===== Infinet has been sold.

I saw that posting. How odd. I have a similar problem with one of my PDP-8/Ls. A retaining nut is loose on one of the three fuse holders. IIRC, the RK05 has an external circuit breaker, but no exernally mounted individual fuses like the power supplies from the late 1960s. I'd suppose your problem is some kind of loose component or connection, but I couldn't suggest where to look. -ethan ===== Infinet has been sold. The domain is going away in February.

Weirdest RK05 problem I have *ever* seen.

by dylanb＠sympatico.ca

I have not even begun to look at the drive yet but I thought I would float the problem here in case someone has actually had something happen as weird as this. PROBLEM: Both drives don't work.. only "Write Protect". Is you tip either drive on it's left side they work fine, (blower starts up, lights, everything..). [not the right side] Looks to be PSU problem but I have not popped the top yet. In all the years I have worked on RK05s I have never seen this! john PDP-8 and other rare mini computers http://www.pdp8.com

It Lives!

I've finally gotten one of my PDP-8/Ls back on its feet - the solution: remove *all* the cards, hose down the backplane with contact cleaner and clean each and every finger of each and every card.

I don't know what's in the contact cleaner, but I have a small case of it I aquired from a now-defunct Commodore Dealer here in town (there are *no* ingredients on the label, nor any references to MSDS sheets, so it must be old). As a bonus, I set up a tripod and an 8mm camcorder and took 1 second shots between each card insertion. I now have a 1.75 minute time-lapse movie of the cards popping in, one by one. What I _don't_ have is a way to digitize the movie. :-( When all was done, I fired up the machine and it ran the following program the first time: 0020 7604 LSW / Clear accumulator and OR in the Switch REgister 0021 5020 JMP 0020 / Do it again Core is fine, power fail/restart is fine, all the front panel switches appear to be fine. This machine hasn't worked right for *years*. A good stiff cleaning is all it took. Now, on to TTY tests and eventually, MAINDECs. One gotcha with this box - one of the fuse holders is loose at the back of the PSU. In its untightened state, it produces an open circuit if I move the box around and don't wiggle it back to its groove. I may need to remove most of the cards to remove the PSU to get to the nut. <sigh>. One down, two to go. -ethan ===== Infinet has been sold. The domain is going away in February.

OMNIBUS LA-180 interface

by ethan_dicks＠yahoo.com

I finally dug out my OMNIBUS LA-180 interface card - M8365, pcb p/n 5011818B. I don't know much about it except that I used a 40-pin cable straight to the parallel input connector on the LA-180, and that whateve IOTs it uses must be the "standard" line printer ones because it took no fiddling with. I plugged it in and OS/8 was happy with it. No muss, no fuss. -ethan ===== Infinet has been sold. The domain is going away in February.

Two PDP-8A questions

The DKC8AA (I don't have the handle number here) - it has two Berg connectors facing front (for the full front panel) and three facing backwards - the one closest to the edge fingers is the serial connector. The other two, for the sake of completeness, are 12-bits in and out. The output port can be used to drive an LA-180, but the data is inverted from normal and the IOTs are not the same. With a recompiled driver, however, you could drive a parallel printer with it. Do you need a copy of the 1977-1978 microcomputer handbook? I have a spare.

Now I'm really subscribed!

by foxvideo＠wincom.net

Friday evening I tried to send a message to CLASSICCMP, and was informed that since I was not a subscriber, I couldn't. Now I subscribed back before the first VCF, so it must have been over two years ago. After several exchanges with "listproc(a)u.washington.edu," I was informed that I was subscribed, and am now getting TWO of each message. Not wanting to tackle that automated system again, I am sending this message in hope that a human being can straighten things out. Regards Charlie Fox Charles E. Fox Chas E.

Apple ][ + but no Floppies

I'm not the original requester, but I have several Apple II systems and no *original* system floppies, just a couple of boxes of bootable stuff from the place I used to write kiddie games at (c. 1984). Given that I do kinda have a working system, is there a way to send Apple II disk images like you can with a Mac? Back in the bad old days, we used to transfer stuff to/from the Apple with a faux-serial cable out of the game port (bit banged TTL to the bit banged TTL port on a C-64, to be precise). I do have an Apple IIc+ that has both 5.25" and 3.5" diskettes, if that helps. Thanks, -ethan ===== Infinet has been sold. The domain is going away in February.

Scary!!! (warning eBay related)

by healyzh＠aracnet.com

I just got a copy of eBay Magazine in the mail today. What a scary thing to have a magazine on. Of course now I'm starting to wonder what kind of list I'm on, that's the second magazine I've gotten in the last couple weeks that I've no idea why I got it. What's really scary is they've got 2-3 pages that are a 'barometer' of how stuff on eBay is doing. The good news is that as far as I can tell, classic computers aren't listed. Zane | Zane H.

If I'm charging a customer $100 an hour to go on site and service their machine, I'm not doing them a favor by installing a heavily-used drive to save a few bucks. And if you want to compare prices, maybe you want to look in the back of a late-70's BYTE, see that a Shugart 801 sold for $350+ back then to hobbyists, adjust for inflation since then, and arrive at an adjusted price today of over $1000 for a new Shugart 801.

Anybody out in the Midland, Michigan area, here's a Heath H89 available. Would seem to be a very good complete system for a person who wants one! It's likely CP/M as it's got the soft-sector H37 floppy drive as opposed to HDOS which typically uses the H17 and 10-sector floppies.

Hewlett Packard A2094 Monitor (Standard RGB ?)

by edick＠idcomm.com

I seriously doubt that the sync signals have any effect at all on the "stereo" vision effect you may observe when playing some games, etc. In fact, at the risk of saying "bah, humbug" about what's obviously a popular feature, the monitor, as far as I can see, can do little to help what's being displayed on it. Of course, being bright, sharp, well converged and linearized, is always better than not. Using a fixed ffrequency monitor on a PC is always a pain in the *ss. No matter how diligently the vendor of these cards calining to make it work have pursued the features, there's always some sort of problem, be it the mouse, the floppy disk, something is going to screw up. I'd advise anyone contemplating this sort of monitor to get an a/b switch as sold by MEI and countless others and use the BIG monitor for WIndows or whatever they want, and use a $10 vga from the thrift store for everything else. That should do the trick with minimal pain. That way they must have a video card capable of supporting their monitor, but don't have to have a custom BIOS rom on it to support the BIG monitor. IF the card you are considering will support the non-interlaced 1280 by 1024 at the vertical rate, or close to it, for which the monitor was designed, you should consider yourself lucky. These won't be cheap, because the video DAC has to be very fast, (run the numbers!) to cough up pixels in 64k colors at 1.12x the product of the horizontal rate and the number of pixels. That $160 card which was mentioned yesterday on this thread was capable, but $160 is not an ordinary price!
