The PC can't do PET disks, either. But you MIGHT be able to interface one of the aftermarket IEEE488 drives to the Pet with some trivial hardware, and then interface it to the PC, and just write a file system for it. Well, no, I wasn't thinking disk-to-disk: >But, if you have a serial port on the Pet, then it'll be easy. I do; as well as Centronics parallel & a P-S converter. As a matter of fact, I archive PC BIOS settings this way when setting up a new system: Plug a P-S converter into the printer port, connect the serial to a laptop, press PrintScreen on each BIOS page and suck it up on the laptop; format, print & save. And speaking of kludges, how's this: I have a client who periodically needs to get data off the network to a standalone separate computer; trouble is, the data is only available on an inquiry screen and corporate guidelines do not permit any foreign S/W on the NT client nor any attachments to the network. So what I did was connect serial-out of the standalone to a serial to PC keyboard converter, serial-in to the client serial-out, and direct client printer O/P to the serial port. The standalone goes through its list of accounts, sends out each account number and the code to bring up the inquiry screen on the serial port (which the client sees as keyboard input), waits a second for the screen to come up, sends a code to print the screen and sucks it back in on the serial port for de-formatting and storing. Slow and ugly, but kind of elegant in its kludginess... >Or maybe you could program the cassette port of a 5150?

Somewhere around here are a few of them. I patched PC-Write to run on it, but never came up with anything else to do with it. Eventually I gave one to Toshiba's MRI division, because they couldn't get one throught their main corporation. Well, it runs dBase II and 123 quite nicely, and I used something called SED for text editing, but even with those excellent expensive 640K 96TPI diskettes one does get used to hard disks. Mind you with all the CD-ROM swapping these days it sometimes seems that we've gone back to the dual-floppy days; thank goodness there is software to put those CD-ROMs on HD. Hate to toss it, seems like the 96TPI drives might be useful some day, it certainly is well built and I happen to have lots of docs, but alas...

Anyone got a spare DSSI terminator?

by classiccmp＠knm.yi.org

Hi, I post about this occasionally, get a response or two, then hear nothing again :&) So here goes again.. I've got a MV3300 here in my kitchen/dining room, and it's missing a DSSI terminator... so if there's anyone out there with a spare.... :&) (Sad state of afairs - the guy I bought this MV3300 from scrapped the second drive enclosure and obviously never took the terminator :&/ So not only do I have a VMS install that expects 3 drives when there are only two there, but I'm also short of a terminator) -- Matt --- Web Page: http://knm.org.uk/ http://pkl.net/~matt/

Folks -- Please pardon the newbie.... I'm trying to track down resources for IBM System/36 and the model 5362. I just Ebay'd one (momentary insanity) and I need to start putting together all the apocrypha to go with it. All I'm getting is the system unit. I need to try and track down software, manuals and a display station first. Any pointers or assistance would be just lovely, and greatly appreciated.

Well, if you're using 18-bit addressing -- which you must be if the DRV11-B responds to 772410 rather than 17772410 -- then all the I/O addresses begin 77.... rather than 17.... 17.... in ODT would address the memory. I/O addresses are often given as 17.... for older QBus devices, because the original LSI/11 used 16-bit addressing. You have to mentally add two or six more '1's on the front for an 11/23 or later processor. > My printer card that I tried to use as a fake ADV11 has jumpers on pin 12 > and pin 8, with the rest removed. Is this correct for setting it to > 170400? No, 'fraid not. This is an LPV11, M8027? The jumpers that go between the two pins in each of the pairs labelled A3 to A12 set the address, a jumper inserted makes it a '0' and "no jumper" sets a '1' in that bit position. You can't control address bits 13 or higher, nor can you control A0...A2. A0 doesn't matter, A1 distinguishs the CSR address from the buffer address (one word higher), and A2 is fixed at binary '1' -- so this card can never be set to anything that doesn't end in octal '4'. If all the jumpers are out except A8 and A12, that would set binary 1110111011111100 as the base address, which is octal 167374. Not quite what you wanted :-) The closest you can get is binary 1111000100000100 (the leftmost bits are already set, A12 should be out, A11...A9 in, A8 out, A7..A3 in, A2 is set to a '1' and can't be changed, and the other two are "don't care") or octal 170404. > I noticed on the DRV11 card that it says jumper in = logic 0.

The jumper sets address bit 12 to 0, so you get binary 1110111111111000. > Are my jumpers on the printer card the opposite of what they should > be? Is 177777 what is returned for a missing board? If I have the > jumpers reversed on the printer card, that would explain that situation, > but it doesn't explain the DRV11, unless its bad. Yes, you have the jumper sense wrong on the printer card. What you get back from a non-existent address depends on the bus termination, but all-ones is plausible. Maybe you have a bad DRV11, or maybe you've overlooked a jumper. At least some of the CSR bits should read as zeros. -- Pete Peter Turnbull Network Manager University of York

Let me try this again

by mranalog＠attbi.com

Hi All, Last week I was looking for someone to host some Data I/O manuals. Sorry about that, I had no idea that they were already on the web. I thought they were created by the person that gave them to me. So now I have some scanned pages that someone might want to host. I believe that these are pretty rare and kind of historic. And again I want to get them out there to be a part of the Great Record and not be misplaced here in the Great Pile. And as before, let me know if these are already available somewhere else. Now the story. Well about 8 years ago I was in my favorite Bay Area electronic surplus store - Mike Quinn Electronics. At the time, they were still in the Quonset hut at Oakland Airport. I bought a pile of books and manuals. And when I got home I discovered among the books 3 handwritten and xeroxed, double-sided sheets stapled together entitled "MINI-MINI COMPUTER". The six pages described the design of a computer built using four core planes from an IBM 1401. At the time it was written, these core planes were available from Mike Quinn's for less than $9 each. The pages had no date on them, just the author's name and address. In 1999 I decided to track down this Hal A. Chamberlin Jr. Hal (I learned) is the author of the well regarded book "Musical Applications of Microprocessors". And I DON'T KNOW, but maybe the same Hal that started "The Computer Hobbyist". I contacted Hal in 1999 (at the time he was in Korea) and this is some of what he said: ---------- Start Quote -------------------------- > I'm searching for a Hal Chamberlin that at one time > lived at 123 Ashe Ave. Raleigh, N.C. > I'm trying to track down information about the > "MINI-MINI COMPUTER". > Thank you for your time, Hi, you've reached me. Where in the world did you find that address? That's where I lived when going to North Carolina State University junior and senior years! Right now I'm living in Korea but will be back in the 'States in a bit less than a year. The "MINI-MINI COMPUTER" is a paper design I did shortly after graduating in response to requests from hobbyists around the country about how to make a core memory unit function. It was a slimmed down version of the computer I had successfully built and run year earlier called the HAL-4096. MINI-MINI was described rather completely on 2-4 (don't remember exactly) hand-printed letter-size pages which I reproduced via blueprint machine. I filled about a dozen requests for copies but never heard of anybody actually building one. I have at least one set of the original blueprints in my archives in America. I take it from your by-line that you have a museum of sorts that concentrates on analog computation. MINI-MINI was strictly digital with 4000 (not 4K) 4-bit words of core memory. Each word could hold one octal digit plus a "flag" bit which was used to indicate the boundaries between words and whether a word was negative or positive. Thus it was a variable word length machine like an IBM 1620. Instructions were 10 digits long and consisted of 2-digit opcode and two 4-digit addresses. There was no accumulator; everything was memory-to-memory so one instruction could do a lot. Although MINI-MINI was probbly never built (at least not by me), HAL-4096 WAS built and ran from around 1970 until around 1979 when I moved from New Hampshire back to Raleigh (it was retired then and didn't make the move because wires in the core memory were corroding and breaking). I have some photos, a newspaper clipping, some of the homemade boards it used, perhaps a memory plane sample, and some software listings. It was a pretty complete system with full console, Selectric typewriter (and later a line printer), card reader, card punch, paper tape reader and punch, and modem (300 baud). Software included a full-featured assembler and BASIC interpreter, a version of which was remotely accessible via auto-answer modem (Bill Gates, eat your heart out - I beat ya by more than 2 years). There were tons of utilities and some experimental music synthesis software (the real reason it was built). I've still got much of the software on paper tapes, card decks, and printed listings. --------- End Quote -------------------------------------- I just contacted Hal again to nail down the date that these pages were written. And he said: --------- Start Quote ---------------------------------- > I was wondering, in what year the handout was written? I graduated with a BS in the Spring of 1970 so that would have been the Summer of that year. I believe that Mike Quinn had suggested that I write some plans for using IBM 1401 core memory planes which he had in abundance at the time and that was the result. It was really based on the then running HAL 4096 which used a larger IBM 1620 memory unit. >Did you know that there is a page at: >http://www.mtu.com/basics/mtufounders.htm that states: >> In 1966 as a college freshman, Hal designed his >> own digital computer (the HAL 4096) using scrap >> IBM magnetic core memory planes and logic cards. >> .... The HAL4096 was demonstrated publicly at the >> 1968 NC State University Engineer's Fair. That web site is run by my former business partner at MTU. The HAL 4096 wasn't really begun until 1968 (beginning of Junior year) when I got the core memory unit from Mike Quinn and some logic boards from IBM where I had worked the immediately preceeding Summer. What was shown at the Engineer's Fair was the core memory and ALU doing "something useful" (don't remember what it was) but the CPU didn't execute the full instruction set and have any useful software until 1969-1970. > Thank you for your time. Many people today are > interested in this kind of history. And your > design is a good indication of the type of serious > projects that were being attempted at the time. Again, feel free to do what you want with the MINI-MINI plans. --------- End Quote ------------------------------------ If these pages are not already available and someone would like to host them, let me know. Like I said before I'm not sure what the effect of many people trying to download this file would be, so I will give the filename to one person. And that person can make them available to anyone interested. The scans are a little rough but then the originals are 30 years old and copies from a blueprint machine. The 6 pages are 8.5x11 scanned at 300 dpi stored as .JPGs and zipped together for a total file size of about 15.5 MB!! Oh! and I'm on digest. Regards, --Doug And if I still have anyone's attention, does anyone know where I can find program to do Group 4 fax compression under Windows 98?

It might work with one, though. > There are no switches at the front of the box, unless you mean the > control panel > which contains the thumbwheel switches and a few other switches? Yes, that's what I meant. The three thumbwheel switches on the left set the start address of the box, in 32KW blocks. That's the smallest size you can have in a box, and since the arrays are either 16KW or 64KW I think you need to have at least two (but you can have an odd number, eg 3, after that -- it just won't do any interleaving). Anyway, set these three to zero. The other thumbwheel (?) switch sets the external interleave; it has to be set to zero unless you are interleaving between multiple boxes. Then the cards have to be in the correct slots. Looking from the front, slot 1 is on the right, and slot 26 is on the left, PSU regulators are at the back. The address buffer (M8158) must be in slot 13, the data buffer (M8159) in slot 15. The #0 Control A board (M8160) must be in slot 11 and the #1 Control A board in slot 16. The #0 Control B board (M8161) must be in slot 10 and the #1 Control A board in slot 17. The #0 controllers handle the even-numbered arrays, in slots 2...9; the #1 controllers handle the odd-numbered arrays, in slots 18...25. Slots 1,12,14,26 are not used. You must set the power-fail jumpers on the M8158. The manual says W1 out, W2 in; W3 out, W4 in. I'm not sure if that's always true. I don't know what you do if you don't want the battery backup! You must also put terminators on the outgoing connectors on the address and data buffers of the last box (the only box, in your case). These are H873 terminator packs, four altogether, one for each BC06R cable. The incoming cables go on J1 and J3 (nearest the long edge of the board), and the terminators go on J2 and J4. You MUST put the screws in the terminators, as that's how they get the power. The first array, #0, must go in slot 9, and the next, #1, in slot 18. Then work out from the centre if you ever add more. There must not be any gaps. If there are some 16K boards and some 64K boards, the 16K boards must all be before the 64K ones. > Do you have documentation on the data buffer board? This one does have 2 > switchbanks, and all are currently 'open'. Those 2 boards are the > only one for which I do not have any docs. I didn't see anything about switches on the data buffer. The address buffer is described as having three switches to set the CSR address of the box. For the first box, set address 17777100 by setting S1, S2, and S3 all closed. For the next box, open S1. For the third, open S2, close S1. And so on.

The MK11 logic checks the address on the bus to make sure it's between the limits set by the size register in the CPU, and it's start address. If the address on the bus is less than the box's start address, or higher than the size register, it will not respond. > > Why do you think address 777644 is the diagnostics ROM start address? > > That was a mistake, I did mean 765744, which is spoken about in the > documentation. That's not an entry point! It's not even executable code, it's the ROM Identification word. It contains the ASCII characters "B0" to identify the ROM. The only entry points are: 773x04 to boot without diagnostics 773x06 to boot with diagnostics aaaaaa address dependant on the bootstrap ROM version, which jumps to 765564 in the diagnostic ROM 765564 JMP to start of diagnostics 765000 start of disgnostic code Obviously there are other points at which you could enter the diagnostics, but you'd need to set some things in memory and registers first. BTW, I discovered you can disable the cache by setting 000014 in the status register at 17777746. If the cache is faulty, but enabled, the memory box won't work properly, apparently. I don;t think that's your problem, though. More like a start address error. The first part of the troubleshooting flowchar starts by saying that you want to boot XXDP and run the MK112 diagnostic program :-) Well, obviously you can't do that, but it does say that if you can't boot, then first check ALL the power supplies (sound advice anyway). The next part of the flowchart goes like this: 1) Can you boot XXDP? If "no", is the memory box ON LINE? If "no", put it ON LINE and go back to (1) If "yes", is MEM PWR READY lit? If "no", "ZAP 200" [I have no idea what this means!] If "yes", suspect (in this order): BA11K regulator 7014251 battery backup regulator 11/70 Unibus problem If "no", reverse or replace the grey box control cable If "yes", is "UNCORR ERROR"? If "yes", go to next sheet [which is too complex to type] If "no", is there an "ADDR ERROR"?

Compukit UK101

by Adrian.Graham＠corporatemicrosystems.com

Hi folks, After the cap questions I got the new ones put back on my bare-board machine last night, re-socketed all the chips, resoldered the power connections etc (they looked a bit iffy) and switched on..... ....and got a screenful of garbage. Hmm. Then I hit both RESET keys..... and got a boot prompt! Woo! At this point I know I can either go into the Monitor or Basic or whatever (ROMS are on the board) but none of the keys would do anything apart from RESET. This made me connect up my other UK101 (with the lovely injection-moulded bright orange case :) and that one gets as far as the screen of garbage and won't reset. I'm suspecting keyboard problems on both machines, but if anyone can remember how they booted that'd be smart. I'm off to check the official UK101 web page to see if there's any tips there too. cheers! a

Ceramic capacitor question

Actually, a lot of these caps will be between the +5V > supply and ground, so the Mapl 0.1uF 16V ones would do as > well. But I'd use the 50V ones. Yup; certainly all of the broken ones were between +5V and GND and I got them swapped over last night - 104Z 50V ones 'cos I found a parking space just round the corner from the shop on my way home, and I got 12 english pence back too :) This brings to mind a separate question that I'll post in a bit. cheers! a

"Locking Connector Kits" for LocalTalk

by mythtech＠Mac.com

>Not necessarily; the C64's video port comes in an 8-pin variety and they >call that DIN-8 also. Much larger, however, than Mac Mini-DIN. I meant isn't the Mac din size (the one I thought you were refering to since you were talking about building an adaptor for a mac telenet connector), isn't THAT a mini-din. I always thought the mac serial size (as well as things like ADB, PS/2, S-Video...) were Mini-Din, and things like MIDI, AT Keyboards, stuff like that was just plain DIN. It always made sense to me, since the two styles are very different in overall size... but then, I always thought a D shell 9 pin connector, as found on things like the Mac Plus mouse port, was a DB-9, where it is really a DE-9... so maybe the mini vs large dins have two different names too. I am fairly sure MCM also sells female DIN connectors in various pin counts, as well as the mini-din ones. -chris <http://www.mythtech.net>

eMag Solutions LLC announces end of life plan for open reel (9-track) tape

by bill_r＠inetnebr.com

Maybe this has already gone through the list. If not, I thought it might be of interest. Seems like the end of an era... http://www.emaglink.com/Articles/17Dec01.htm Atlanta (December 17, 2001) - eMag, the last manufacturer of open reel (9-track) tape, is announcing its end of life program for users of this product. eMag, which has produced open reel (9-track) tape in its Graham, Texas facility for over 30 years, has determined that the significantly decreased demand for this once dominant magnetic media format mandates an organized end of life announcement and program.

If you need to drive logic with CMOS input levels you could run into difficulty. Pull-up resistors may be required. I couldn't drive logic level mosfets and some Analog Devices parts with MAX3064 using 3V3 supply. The 'byteblaster' parallel port JTAG programmer can be a bit erratic. I had to decouple some of the JTAG signal lines with 47pF caps to make it work. Atmel's free software is really easy to use once you get used to it. Also, don't forget to tie un-used input pins to ground or Vcc. Because I was never happy with Atmel's MAX3000 output stage I switched over to using Xilinx Coolrunner. The Xilinx parts have a true complimentary output stage and you get proper rail to rail drive levels, they're also lower power too. On the downside, you have to buy a Xilinx JTAG programmer and their software leaves a great deal to be desired. Good luck Chris

WTB: Tandy items

by jhellige＠earthlink.net

I was wondering if anyone might have any of the following Tandy catalog numbered items in their piles: TV/Joystick board (26-5142) Vianet networking board (26-1220 or 26-1221) DCS interface kit/board (26-5147) All of these boards are for the Model 2000 and have the 96pin euroconnector. The DCS is the interface board for the early Iomega Bernoulli drives. Truth be told, I wouldn't be picky if someone had anything related to the Model 2000 to offer up!

"Locking Connector Kits" for LocalTalk

by mythtech＠Mac.com

>And here is my follow-up question... Is there an *easy* way to get the cover >off of a DIN plug without making anymore new scars in my fingers? At least the ones I've worked with, there is a small locking tab on the casing (kind of like a finger that drops into a hole). I stick a small flat blade screwdriver under that, and then push the cable (and connector by proxy) out. If there isn't a cable attached already, then I stick a screwdriver (usually philips) into the end where the cable would go, and push the insides out. -chris <http://www.mythtech.net>

Almost On-Topic: DEC AHA1742B Firmware

by doc＠mdrconsult.com

Hi, again. I just tripped on my Jensen box looking for the dial calipers, and that reminded me. I have a DEC 2000/150axp, working, and a copy of Digital Unix v4.0, licensed, that I want to run on it. The problem is the EISA SCSI firmware. The OS wants firmware version G2, my AHA1742 has version G1. I tried the firmware images from Adaptec, but the DEC installer hurls on that too. Does anyone know where I might find DEC firmware upgrades for the SCSI adapter? Burning the EEPROMs isn't a problem. This box is only 9-and-a-half years old, so you'll all please excuse me. ;) Doc

eMag Solutions LLC announces end of life plan for open reel (9-track) tape

by steven_j_robertson＠hotmail.com

Haven't looked recently but, they show up on ebay quite often. Prices are typically in the $2.00 - $5.00 range per tape. About two years ago, I bought 30 boxes of new 2400' tapes. As I recall, I paid $3.00 per tape (with shipping). I'd be willing to part with some but, since I'm recently unemployed, I gotta make some money on the deal.

Toshiba T3200SX Question

! From: Tothwolf [mailto:tothwolf@concentric.net] ! ! ! You can remove NiCad leftovers from the boards/parts with ! vinegar after removing the battery.

Apple disk -> MSDOS

by RCini＠congressfinancial.com

I believe that the Diamond Trackstar can use a PC floppy drive to read an Apple II disk by using a special passive cable between the Trackstar board and the floppy. For me, I use a real Apple drive connected to the Trackstar. Otherwise, I use ADT to get apple disk images into and out of the Apple<=>PC. For preservation of BASIC listings I would get a super serial card for the Apple, null-modem connect it to the PC, do PR#2 and then "list" the program to a terminal program (with screen logging ON) running on the PC. This same trick, console redirection, is used to get the Apple portion of the ADT program into the Apple (except using IN#2 I believe). Rich ========================== Richard A. Cini, Jr. Congress Financial Corporation 1133 Avenue of the Americas 30th Floor New York, NY 10036 (212) 545-4402 (212) 840-6259 (facsimile) -----Original Message----- From: M H Stein [mailto:mhstein@usa.net] Sent: Tuesday, January 08, 2002 11:28 PM To: 'ClassicComputers' Subject: Apple disk -> MSDOS Do I gather from previous discussions that it's a problem reading an Apple II floppy disk on a PC? I'm about to get rid of my last Apple II clone (No, Ernest, I haven't forgotten you) but there are some Basic programs on Apple diskettes that I might want to port to GW-Basic some day.

VTech Laser 50?

by doc＠mdrconsult.com

Does anybody know anything about this thing? The local thrift shop has one that they claim works (but they don't know how to work it), with everything but an AC power supply. It comes with a very broken box, or pieces of it, instruction manual and a Basic tutorial. The sticker on the back says 1985. The console itself is cosmetically perfect. I didn't get it yet, because there is a compartment at the back that appears to take some kind of cartridge. Is that part necessary for use? It also has a narrow male card-edge connector at the back, maybe 18 or 20 pins. What's that? Not surprisingly, there's not a lot of information about it on the web. Mostly Google turns up old posts to classiccmp mailing list.... Doc

Astronautics ZS-1

by auringer＠tds.net

Hi William, > What kind of window are we dealing with? A week? A month? I think I need a commitment this week or next at the latest. Our HQ is in a hurry to get this stuff taken care of. I found out this morning that they are sending maintenance people here tomorrow (tuesday) to pick some stuff up. I am in the process of stripping three "spare" ZS machines so they can take the chassis and power supplies. I know these three would never be viable as complete systems, so I want to get all the usable stuff out of them. > Quite interested, by the way. I think I know people that worked at > Astronautics.

Ceramic capacitor question

by Adrian.Graham＠corporatemicrosystems.com

Another question from me :) The Compukit UK101 has several ceramic capacitors, all marked 104Z 25V, which judging by what I've found on the web so far makes them .1uF. My local Maplins (sorry, that seems to be a swear word in some parts) only has 224Z at 25V (I'd guess .2uF?) and 104Z at 50V, half the size. What can I get away with? Or am I right in assuming I need to match exactly?

Back to board washing for a moment

by Adrian.Graham＠corporatemicrosystems.com

Having read all the threads relating to board washing I've got a question. What are the panel's thoughts on video boards? I'm thinking of flyback transformers and the like......got a PET 8032SK here that I'm picking up on fixing again after a couple of months layoff - it's taken up smoking...... Anyway; it's been turned off since early november time, and since the board has a thick layer of greasy grime all over it I want to give it a wash since I can't see where the smoke's coming from apart from 'close to the front at the right'..... Any help appreciated -- Adrian Graham, Corporate Microsystems Ltd e: adrian.graham(a)corporatemicrosystems.com w: www.corporatemicrosystems.com w2: www.binarydinosaurs.co.uk (Online Computer Museum)

CCITT G4 compression in WIN98

by djg＠drs-esg.com

>> It turns out that Windows comes with a program that >> does CCITT Group 3 and 4 compression. >well what was it! > Since I didn't see the author answer, I think is is the windows imaging program. Also called wang imaging and kodak imaging in various versions. Start->programs->accessories->imaging Use menu page->convert->compresssion and select CCITT Group 2(2d) Fax. I think this choice moves around some in the menu structure for the various options. You can also make that the default for scans under another menu. Didn't work properly with my sheet feeder though. Can do simple cleanup on the scans. Very fast for displaying and paging through the tiff files and doesn't have the display artifacts that Adobe PDF viewer sometimes has.

The simple > Windows telnet client provides only VT52 and VT100 emulation. This is one of those things that is poorly understood and apt to be implemented incorrectly and/or differently by different people. Telnet tries to provide a "network virtual terminal" abstraction, and one of the bits of that abstraction is encoding a "newline" across the Telnet connection. This was important way back when a terminal or host might send CR, LF, CR LF, or some other character sequence to indicate newline; and there was some thought being given to how to make it so you could use any terminal+host as a network virtual terminal to another host. The Telnet RFC provides two encodings: CR NUL and CR LF. When I worked on WIN/TCP for MPE/V I tried to make the Telnet server use CR NUL to mean "return the carriage to the left margin" and CR LF to mean "return the carriage to the left margin and advance to the next line" (there were MPE FWRITE carriage-controls that needed to be mapped to these). What I can't remember right now is whether that worked or whether I later changed the server to send CR NUL LF in some cases to appease clients that turned CR LF back into "return the carriage to the left margin". If a Telnet negotiates binary mode (sends IAC WILL BINARY and receives IAC DO BINARY) then it is saying that it will send raw 8-bit data and not do this NVT stuff. And of course some Telnet clients just do whatever, so just send CR when the user presses RETURN or ENTER. This is Wrong, but "be liberal in what you accept", so what you need to do for the NVT (non-binary) case is to run received data through a state machine: when you receive CR you enter a state for the next character where a NUL or LF is discarded but other characters are treated as received data. -Frank McConnell

QBus IDE Controller

by doc＠mdrconsult.com

Most of y'all have probably seen this thread, but considering the rarity & price of medium/high capacity storage controllers, I thought this worth posting. There's a thread ongoing on alt.sys.pdp11 about a working QBus IDE adapter. The designer has a working prototype, 2.11BSD drivers, and a NetBSD driver in progress. He's asking for input as to interest in developing & producing these, and has docs, schematics, and I think drivers up at: http://www.chd.dyndns.org/qbus_ide/ Doc

TCP programming question

by RCini＠congressfinancial.com

Hello, all: I'm having trouble tracing down an intermittent problem with the Altair32 Emulator which as you know uses a telnet server to simulate a console. I occasionally seem to get two command prompt lines after hitting <ENTER> wich would lead me to believe a translation issue? Does anyone know if there is CR/LF translation across the telnet channel? For example, if I hit <ENTER> in the telnet client, does that produce <CR> or <CR><LF>? Is it dependent on the client settings? The simple Windows telnet client provides only VT52 and VT100 emulation. A quick search of the MSDN does not reveal any mention of CR/LF translation in bind, listen, accept, connect, recv, or send. Any thoughts? Rich ========================== Richard A. Cini, Jr. Congress Financial Corporation 1133 Avenue of the Americas 30th Floor New York, NY 10036 (212) 545-4402 (212) 840-6259 (facsimile)

VAX 11/780s - Masscomp - Valid equipment available

Hi Pat, > From: Pat Finnegan <pat(a)purdueriots.com> > How big is your smalled 9track tape drive, where are your located, and > would you be willing to ship? Also, how big/heavy is a DECWRITER III? The smallest 9-track would be the slot loading Cipher F880640-90-1025U from the Valid systems. It fits a standard 19" rack and is about 8-9" tall and probably 24" deep. A quick hefting of the drive feels like 70-90lb. The front load StorageTek units are also rack mount, but are about 24" tall. After removing one yesterday I would say it weighs about a ton, but more likely about 100lb. Two people would be a very good idea. A Decwriter is like an oversize typewriter with its own table. The Decwriters are the consoles for the VAXEN, so I would think they should stay together, unless the new VAX owners don't want them. Later, Jon Jon Auringer auringer(a)tds.net Madison, WI

That's an excellent starting point; 6 & 14 volts is ringing bells with me, and there are some caps on the motherboard which could be part of a regulating circuit. Pinouts match too, I think.

There are no switches at the front of the box, unless you mean the control panel which contains the thumbwheel switches and a few other switches? Do you have documentation on the data buffer board? This one does have 2 switchbanks, and all are currently 'open'.

That sounds more logical to me, but I can only substantiate that when I have the memory being available at address 000000. As a tryout, I'll swap all the other boards in the cpu (I have a complete spare CPU) to see if this has some effect as well. I didn't do this before, as the machine was in operation until about a year ago, so it is likely to assume that this could have worked. I do not know if the MK11 is the original one, or is from another 11/70. I'll let you know tomorrow.

VAX manuals

by doc＠mdrconsult.com

No, it's not yet another Gray wall... I have 2 packages of VMS installation docs, "VMS Installation and Operations VAXstation 8000" Order Number AA-LB33A-TE "VMS Installation and Operations VAX 6000 Series" Order Number AA-LB36B-TE Both are 5-ring insert sets, maybe 20-30 sheets + tabbed divider & end divider, and both are "new", in shrinkwrap. They were lurking in my Gray Wall. Anybody want them? Doc

11/53 - DELQA question

by GOOI＠oce.nl

Thanks everybody for the clear replies. I removed the bus expansion card (for the external box) and when I powered up the system again, it just ran fine. The next step I did was move the RQXD3 to the location where that bus expansion card was and where the RQDX3 was I inserted a DELQA (M7516). I connected the bulkhead cable and mounted a 10Base2 transceiver on the AUI connector. The 10Base2 transceiver has the bare minimum network: just the T-connector with on both sides 50 Ohms terminators. The system still boots and runs fine, but I expected to see the XE: (?) device listed with the $SHOW DEVICES command. (The system runs Micro/RSX 3.1). Current config: slot 1 A/B-C/D : M7554-02 KDJ11, 15 MHz, 1.5 Mb slot 2 A/B : M3106 4 line EIA MUX slot 3 A/B : M7546 TQK50 slot 4 A/B : M7516 DELQA C/D : M7555 RQDX3 all other slots are empty. Must the system with the new DELQA interface be sys/generated? Am I doing something wrong? TIA - Henk.

Seeking classiccmp email solution

by acme_ent＠bellsouth.net

Greetings. I would like to use one of my classic machines to handle all of my email. Currently, I'm using a Win95 PC. Because it contains classic gear (Voyetra V-24S 64 port MIDI i/f) as well as brand new stuff (Audiophile 2496 hard disk recorder), it contains a strange mix of DOS, Win 3.1, Win95, and Win98 drivers. This weirdness is the only way to enable *all* of the stuff in this box to work together. After four virus attacks in December alone, I have decided to move my email capability *off* of this box before some virus catches me off guard. It takes about four hours to wipe and reload this system and massage all of the drivers until all the hardware is happy; I would rather avoid this painful task. So -- how hard would it be for me to handle email on a small, classic micro? I'd like to use my Z100 running CP/M-86; second choice is my Kaypro 10 (2.2, of course); third choice is the Z100 under ZDOS. My BellSouth dial-up account does not provide shell accounts, but I see that there are plenty of free providers out there. Is it possible to get my classic machine to first connect with my BellSouth dial-up, then log on to a shell account, and then send mail or retrieve my incoming mail for offline viewing? I'd prefer to cobble together some sort of system using other people's software, but I am a programmer and can write stuff in C or assembler if need be. Please bear in mind, though, that I have no knowledge of the internal workings of TCP/IP, Telnet, POP3, etc., and I don't really want to spend three months learning the protocols and writing and debugging the code -- but I will if I have to. Feedback from the list members concerning this idea would be greatly appreciated. Glen 0/0

Strange and Possibly Wonderful Cable

by doc＠mdrconsult.com

Hi. I picked up a 35lb load of mostly Mac-related cast-offs last night, and scored many cool objets de junque. The 2 things I can't really identify are a Panasonic Easa-Phone, KX-T1225 which seems to be a speed-dialer of some sort. The other is a cable with a (Doc ducks & prepares to rub) 36-pin Centronics connector, plus eyelet ground, on one end and a female card-edge connector on the other. The shrouds are steel, squared, and embossed "TANDY" on both ends. While I've never seen one, I'm guessing it's a Tandy printer cable. The rest of the haul is mostly OT, but see gimme list below: working SyQuest 88MB drive & some cartridges cordless 3-button mouse a whole bag of the fabled 800K floppies 2 copies of FWB's Hard Disk Toolkit (one is even on-topic, I think. System 6.0 bootable disk) The newer version came with docs CharisMac Anubis that I can't date, but there's NO version info in the docs, copyright is 1989-1996 Astarte Toast CD-ROM Pro v3, in original box but no docs Adobe PageMill v2.0, no docs no key Adobe Photo Deluxe no docs Adobe Illustator v6 no docs no key (Waahhh!!!) A couple of NuBus ethernet adapters, one with its right-angle adapter A loose right-angle NuBus adapters with *2* female connectors several Apple-AUI/10B2 transceivers 14400 (no AC adapter) SupraFax modem (needs 9V AC PSU) 33.6 SupraExpress modem with all its parts GeoPort Telecom Adapter - first one I've found in the wild 2 28.8 SupraExpress modems, intact 1998 revision of the "Mac Upgrade and Repair Bible" with its CD. Not bad for free. The transceivers, the 14.4 modem, the Tandy cable and all the NuBus cards are all up for adoption; the rest is probably available for trade if you need something. All this because I gave $35 for a PowerBook 145B I didn't want and the QuickTake 150 (with all its docs, disks, and a NIB Battery Booster Pack) that I did want last week. Yee Haw. Doc

The software probably checks for the presence of a device at the address(es) it expects for the ADV11; that's very easy to do (just set up a trap handler in case it causes a bus timeout, then try to read from the address. If it doesn't cause a trap, the device is there.) The standard adresses for an ADV11 are 170400 for the CSR and 170402 for the Data Buffer Register. The standard addresses for a DRV11 are 167770 for CSR, and 167772 and 167774 for the OUTBUF and INBUF registers. If you haven't got an ADV11, I can think of three options open to you: 1) get an ADV11 2) get a 3rd party equivalent, such as an ADAC card 3) use some other device, set it to the ADV11 addresses, and hope you fool the software -- Pete Peter Turnbull Network Manager University of York

Manual available - Heathkit ET3400 trainer

by west＠tseinc.com

Greetings folks; Someone was kind enough to copy a manual for the Heathkit ET3400 microprocessor trainer for me. NOT complaining, but it was single sided copy, and I'm anal so I went and copied it from single sided to dual sided 3 hole paper for myself. As a result, I have a single sided copy left over that is free to anyone that wants it for the cost of mailing. It is not a 100% complete manual, but the pages that are missing were skipped intentionally as they were far from essential. I'm a stickler for that sort of thing and I can assure you the missing pages won't dissapoint you. If someone wants it, speak up or the duplicate will probably go into the trash. Regards, Jay West

Trailing-edge compute farm seeks gainful employment

by Golemancd＠aol.com

This is becoming a pretty silly thread because there can be understanding without proper grammer ; if we are being technical here. Sure there is meaning, u just dont understand it. The real story here is this is pretty much a none issue since what i am saying and pretty much what everyone is saying here, is just to enjoy a hobby. To worry about someones ideas to the point that it bothers u defeats the purpose of a hobby; to have fun or to enjoy yourself. If you cant understand something ; it doesnt matter. This is not a business or the F.B.I ; it is just a hobby. I get your point. I do use a lot of shorthand and because this is a hobby i dont focus very much on my grammer. If u see me post then dont read it. That is all that i have to say about this matter. joee P.S i hope the grammer helps you understand this.

If you know its address, try to access the CSR from ODT. For example, if the CSR is at 772410 (which is the default) then if you type that address at the ODT prompt, followed by a '/' (without the quotes), you should see the contents of the CSR. If there's nothing at that address, trying to read it will cause a bus timeout, and all you'll get is a question mark and a new prompt. > Also, can anyone point me to a document that gives a good overview > of the LSI-11 bus, so that I can understand what I'm doing when I change > these settings (such as base and vector settings)? Probably the Microcomputer and Memories Handbook 1982 is your best bet, as it covers the 11/23, LSI-11 and 11/2, various memory boards (including your MSV11-D and MSV11-L), and has sections on the processors, architecture, and so on. You sometimes see them on EBay. I think that was the last (or 2nd-last) QBus CPU/memory handbook. There are at least one or two earlier editions that would have the same general infomation, but not the specific bits about 11/23 and contemporary memory, or 22-bit operation. There's a companion volume, PDP-11 Microcomputer Interfaces 1983-84, which you'd find useful. It has all the information about the BA11-M/N/S backplanes and many peripherals, including your DRV11-B. Apart from that, have you looked at the Micronotes at http://www.ibiblio.org/pub/academic/computer-science/history/pdp-11/hardwar… ? -- Pete Peter Turnbull Network Manager University of York

And to be honest, if you are running anything other than RT11SJ, you probably have a lot more than 28KW of memory anyway, so the saving is minimal. My advice would be not to bother trying to squeeze another 2KW out of the system. -- Pete Peter Turnbull Network Manager University of York

PDP-11/23 upgrade paths

I've found info in the micronotes about upgrading a Micro/PDP-11 to use the KDJ11-A CPU, but I've been unable to find out anything regarding the new versions of this board. In particular, will a KDJ11-BF drop into a Micro/PDP-11 that currently has a KDF11B-BH CPU? The box also has a Clearpoint 1 MB RAM board; any idea of this will work as well?

Astronautics ZS-1

by auringer＠tds.net

Howdy, Is there anyone here that would be interested in rescuing an Astronautics ZS-1, or maybe a couple? I am currently the Systems Admin for the Astronautics Technology Center in Madison Wisconsin. Our facility has been sold and our staff may, or may not, be relocated. Either way, the plan is to scrap the several ZS-1 mini-supercompters that we designed and built here. If I can find someone who has the resources to pick up these machines, I may be able to persuade our management to OK it. Unfortunately, the time window for doing this is very limited. Our headquarters wants to come dismantle these machines ASAP. These machines are are large, they require a lot of power, and will _NOT_ be supported in any way by this company. Each machine is a tall double-wide rack with a third rack for a Storagetek 9-track tape drive. If you need more information on what these machines are, or are capable of, I suggest searching Google. If you have any specific questions, please feel free to e-mail me. Later, Jon Jon Auringer auringer(a)tds.net

Sequent Symmetry S2000-450

by spedraja＠ono.com

Hi, Christopher. Mine is one Sequent Symmetry 2000 with four 486 processors and 256 Mb of memory. I comes with one extension box with over 10 Gb of SCSI disks. It uses Dynix like OS. I'm in treats to get one Sequent Symmetry 5000, with 4 Pentium processors, 1Gb of memory and 10 Gb of disk. Both systems can be take with OS, Tapes, Documentation and so. The best of all os the possibility to get another one Sequent 5000 same than the other but... with one 65 Gb storage Extension box of 180 cm high. Good find if reliable. Don't think so ?

Sequent Symmetry S2000-450

by csmith＠amdocs.com

Hi Sergio, Sequent was/is relatively stingy with information. They are now owned by IBM, who wouldn't even talk to me about my old machine. That said, the Symmetry series may be the closest thing to a real parallel computer that was ever done with Intel CPUs. They're very cool machines. I don't know the exact models you're seeing. Mine is a Symmetry S81, which accepts up to 30 386/16Mhz CPUs and accompanying Weitek co-processors. It is in a coke-machine sized cabinet, and impresses people even without the CPU cards ;) Regards, Chris Christopher Smith, Perl Developer Amdocs - Champaign, IL /usr/bin/perl -e ' print((~"\x95\xc4\xe3"^"Just Another Perl Hacker.")."\x08!\n"); ' -----Original Message----- From: SP [mailto:spedraja@ono.com] It's possible I could obtain one Sequent Symmetry S2000-450 in a relatively short place. A similar system can be viewed in this eBay address: http://cgi.ebay.de/aw-cgi/eBayISAPI.dll?ViewItem&item=1311505028&ed=1009557… The system comes complete, with software, hardware and documentation. It need three pallets to be transported. There is another opportunity to get one Sequent Symmetry S5000 that uses 4 Pentium processors and 1 Gb of memory, but this is in private negotiation. Do Somebody has information about these systems ? They appears to use Four processors 486, a Numa architecture to share memory, and one version of Unix named Dynix. Is there some porting of the Gnu utilities to it ?

7/01/97 ClassicCmp FAQ - Part 1

by marvin＠rain.org

With so much OT stuff going on, this FAQ might be interesting reading for some of the newer members of this listserver. And just for the sake of curiosity, who has been on the list the longest? I joined sometime around June 5, 1997. NOTE: This is an OLD FAQ and the contact information is OUTDATED!!! I do not know if the listserver commands still work, Jay??? ============================================================================= DO NOT DISPOSE OF THIS PART OF THE FAQ. THIS IS THE PART THAT EXPLAINS HOW YOU CAN SUBSCRIBE AND UNSUBSCRIBE. IT WILL TAKE ME MORE TIME TO DO THESE THINGS FOR YOU THAN IT WILL TAKE FOR YOU TO DO THEM YOURSELF ============================================================================= ClassicCmp - The Classic Computers Discussion List Part 1 in the ClassicCmp FAQ Trilogy Mail/Internet Basics FAQ (Frequently Asked Questions) v1.2 Last Update: 7/01/97 ----------------------------------------------------------------------------- This FAQ is written with the primary purpose of making readily available answers to the more common questions appearing on ClassicCmp. It is Maintained by Bill Whitson <bill(a)booster.u.washington.edu>. The infor- mation in this document has been gathered from a variety of sources but, in general, the members of ClassicCmp should be credited for all contain- ed herein. I have, of course, endeavored to be as accurate as is possible and often failed ;). This FAQ is Part 1 of the ClassicCmp FAQ Trilogy. The information presented deals with the use of mailing lists and internet-specific tools. If you have questions, comments, or corrections (always welcome) please contact me at the address above. A current copy of this FAQ is available on the web at http://weber.u. washington.edu/~bcw/ccl.html or via anonymous FTP at 140.142.225.27 in the directory /pub/classiccmp/faqs as classiccmp.faq. ---------------------------------------------------------------------------- Updates: New Sections: 2.1, 3.1 ----------------------------------------------------------------------------- 1. Mailing Lists ---------------- 1.1 Mailing List Basics 1.2 How to Talk to the Robot How to set to Digest How to Subscribe How to Unsubscribe 2. FTP ------ 2.1 FTP Basics 3. World Wide Web ----------------- 3.1 WWW Basics ============================================================================= 1.1 Mailing List Basics A mailing list is a simple device which takes an e-mail and redistributes it to a group of people. People can add and remove themselves from the distribution list by Subscribing and Unsubscribing. When you send a message to the list, it is first examined by the robot for key words that tell it to process an automatic funtion (like help, subscribe, unsubscribe, etc). If the message does not contain a keyword it is sent to the distribution list. 1.2 How to Talk to the Robot There are a few List Processor commands that you might want to use. To send a command to the list processor, write a message to listproc(a)u.washington.edu (Do NOT send the message to classiccmp(a)u.washington.edu). In the body of the message (not the subject line, that is) write one of the following commands, then send the message. SET CLASSICCMP MAIL ACK Tells the robot to send you a copy of messages you write to the list. This is the default. SET CLASSICCMP MAIL NOACK Tells the robot NOT to send you a copy of messages you write to the list. I don't recommend this. SET CLASSICCMP MAIL DIGEST Tells the robot to send you a digest of messages rather than each as it is posted. With this option you will get a weekly bundle of messages and keep a nice, tidy in-box. SUBSCRIBE CLASSICCMP Your.Address Subscribes you to the list. UNSUBSCRIBE CLASSICCMP Your.Address Removes you from the list. [][][][][][][][][][] 2.1 FTP Basics FTP is a protocol by which files can be transferred over the internet. You can use FTP to connect to a remote site and retrieve files. The commands you use with FTP depend on the software you use. In general you must make sure that you are in BINARY mode before transferring a program file or compressed files. The process of downloading a file is usually termed GET and the process of uploading a file is usually termed PUT. Your FTP program will require an address to connect to. For the ClassicCmp site that address is 140.142.225.27. You then may be asked to log in (unless your program assumes an anonymous login). When asked for a name, use anonymous. When asked for a password enter your internet e-mail address. [][][][][][][][][][] 3.1 WWW Basics The only complicated thing with the WWW is knowing what bells and whistles your web browser supports. You don't really need to know much other than the address for ClassicCmp. The web site is all text which means just about any web browser from the oldest Lynx to the newest Netscape or Microsoft browser should support it. The ClassicCmp site is http://weber.u.washington.edu/~bcw/ccl.html. =============================================================================
