PDP-11/34c website?

by GOOI＠oce.nl

Hi Jonathan. Check out http://archives.decdocs.org Click the link "print set archive" There you find, among others, the Print Set of the 11/34. The folder "manuals", down the list, contains all you need. KD11, FP11, KK11, M9312, etc. Especially look at the KK11 manual. It describes the step you must do to install the cache next to the FP taking into account the power distribution. It works, I did this at home with my 11/34A. BTW you need a special "over the top" connector to connect one CPU board + cache + FP board .... Sorry, I do not have a spare one. Does an 11/34A with FP and cache become a "PDP-11/34C" ? Good luck with the conversion, - Henk. > -----Original Message----- > From: Jonathan Engdahl [mailto:jrengdahl@safeaccess.com] > Sent: vrijdag 12 april 2002 4:20 > To: classiccmp(a)classiccmp.org > Subject: PDP-11/34c website? > > > Is there a website somewhere that will tell me exactly how to > put the boards in an 11/34c?

Any interest in ROM 00 Apple IIgs?

by r_beaudry＠hotmail.com

Hello all, I have in my posession, three tested, working, Rom 00 Apple IIgs machines, complete with monitor, 3.5" and 5.25" floppies, keyboards, and mice. I am wondering if anyone would like them, for a nominal price + shipping. Before anyone misunderstands me, I am not asking for tons of money for these beasts, as I realize they're pretty crippled (They had defective video chips, and the ROM version doesn't allow you to run GS/OS). They do run most Apple IIe sowftware, and could be considered as an accelerated IIe. Not the best example of a IIgs, however, if you are looking for a machine to complete your collection, they are available. Note that NONE of them are the "Woz" variant. I got these (along with several "ROM 01" and "Rom 00 upgraded to Rom 01" IIgs machines) from a local school. I would like to save them from the dump, and help the school out as well. Therefore, I will take offers on these machines until Thursday 04/11, 11:59PM Eastern US time. ANY AND ALL proceeds will be donated back to the school the computers came from. I will separately notify the highest bidders that they have won.... Your chance to own a small part of Apple II history, and help out a local school as well.. I will ship anywhere, worldwide, that the US Postal Service allows me to ship, and I will consider shipping just a CPU (i.e., no monitor, or no drives, or whatever combination you want), as it will cut down on shipping... The units will be shipped from US ZIP code 01473, and to give you an idea, a monitor weighs about 25 lbs boxed, and a CPU weighs (I think) 8 lbs. boxed... I will quote actual weights and shipping charges to anyone who asks.... Thanks!

For what it's worth, you can get them refurbished from Plextor, supposedly, for about US$95 for a SCSI cd-rw of some sort. That's probably the best price I've found on them.

Amiga 2500 questions

by doc＠mdrconsult.com

Hi. I'm looking at an Amiga 2500, with a 5M hard drive, unknown ram, a lot of boards in it (the owner knows as little about it as I do), and no keyboard, mouse, or display. He wants $30 for it. He has a display >from a Commodore Colt hooked up to the composite video port, and the 2500 will boot to a screen with hand holding a WorkBench 1.3 floppy shown. Are keyboards as hard to find as it seems? That's the showstopper so far. Is $30 reasonable for a partially tested A2500? Will the kbd/mouse from the Colt work? Aquiring minds want to know. :) Doc

> -----Original Message----- > From: Douglas H. Quebbeman [mailto:dquebbeman@acm.org] > To capture an existing CD-ROM into an image file, most > likely, Chris is correct, but I haven't gone that direction > yet. I have. It works as long as the block size isn't odd. Generally any cd will take a block size of 2048 bytes, however, if the CD is "bad" (scratched, or what not), a smaller block size (1 ;) may help you get more good data at the expense of some speed. You can also use the conv=noerror option to ignore read errors if you really want whatever data you can get. As somebody else mentioned, cat works too, but it doesn't have an option to make it ignore read errors and keep going. Otherwise, you're right, use mkisofs, or mkhybrid to make a filesystem from some of your files, and then use cdrecord to burn it. There is another program (cdwrite?), but I don't think it has nearly the same level of device compatibility, not to mention that the number of systems cdrecord will build for is very impressive.

Semi-OT: Power supplies

by pat＠cart-server.purdueriots.com

I am looking for some sort of service manual or something on two Power supplies I picked up yesterday at Purdue Salvage. The first one is a HP 711A 'adjustable AC/DC power supply', which is fairly old and tube-based. After plugging it in, nothing happens - no filaments light up, etc. I haven't had time to go through and 'probe' it to see if the transformer is still OK yet, that's my next step. If anyone has any info on it, please drop me a line. BTW I've checked the fuse. The second one is fairly new - a HC Power Model HC10-1A switching 5V, 200A power supply. I think it was manufactured in 1992, making it 'just classic' as far as electronics go. I've taken it apart, and the line-side smoother caps are charging up, so I'm guessing a control problem. I'm going to try and contact Power-One (they aparently bought out HC Power) tomorrow to try and get info on it. I would really like to get this working so that I could try and use it for my new SSI/MSI (perhaps a few PALs if necessary) minicomputer I'm designing. [Aside: If they'd only give me some sort of course credit towards my BSCompE for doing this, I'd be really happy.] -- Pat

Gould 9540 PSU

by red＠bears.org

I've recently inherited a Gould 9540 (8 MHz MC68000 CPU, Multibus) which would appear to run some sort of UNIX variant (System III, if I had to guess) I'd like to check it out, but the system sports a rather large sticker on the back panel which states it was wired at the factory to run on 240V. Before I spend a lot of energy trying to figure out whether it's still true and how to strap it for 120V operation, I thought I'd ask if anybody knows how to tell, off the top of his or her head. ok r.

OT: BLAME WHO????????? (Warning: Possible Humor)

by rigdonj＠cfl.rr.com

BLAME WHO????????? Let's see if I understand how the world works lately... If a man cuts his finger off while slicing salami at work, he blames the restaurant. If you smoke three packs a day for 40 years and die of lung cancer, your family blames the tobacco company. If your neighbor crashes into a tree while driving home drunk, he blames the bartender. If your grandchildren are brats without manners, you blame television. If your friend is shot by a deranged madman, you blame the gun manufacturer. And if a crazed person breaks into the cockpit and tries to kill the pilot at 35,000 feet, and the passengers kill him instead, the mother of the deceased blames the airline. I must have lived too long to understand the world as it is anymore. So, if I die while my butt is parked in front of this computer, I want you to blame Microsoft and Bill Gates ...okay?

NEC Multispeed boot error... what now?

I am hoping you can send me in the right direction for restoring this very old laptop that my father gave me. It is posting a message that reads as follows: Fixed disk setup (1701) incomplete. Trying to boot from A drive: Warning!! Fixed Disk Controller is bad or Low Power, Can not boot up from fixed disk, insert system disk drive A or B... Press any key when ready.... What precisely do I need to look for when getting a system disk for this computer? It didn't have anything in the original bag it came with. The screen reads as follows when I turn on the computer: Phoenix ROM BIOS Version 2.51 Copyright (c) 1984,1985,1986 Phoenix Technologies, Inc. NEC Multispeed Please offer any guidance you may have!

Questions regarding Tom Shoppa.

by Antonio.Carlini＠riverstonenet.com

>Why is 212992 magic? OK. I'm an idiot :-) RT-11 has a limit on disk size, and my (poor) recollection is that this might be in the region of 64K blocks (512 byte block ... i.e. 16MB per disk). This would be 16384 2048-byte sectors. 13*16384=212992. So my guess is that when you use this RT-11 CD on an RT-11 system, you tell it to map partition 13 (and 14 etc. onwards to the end). In which case writing an image would be a breeze. Create your ISO file system as a binary (ISO9660) image file and overlay onto an image of a full 650MB or 700MB CD. Create images of however many RT-11 "disks" you think you can fit onto the end. Determine where the next 16384 2048-byte boundary is and drop your first RT-11 partition there, then keep overlaying further partitions until the end. OK. I don't know how to do this on Windows 98 with the available tools, so you'll either have to do it on Unix (or OpenVMS) or knock up a quick tool in C for Windows. Or you could ask Tim how he did it (but I bet W98 was *not* part of the answer!). Antonio

Of course, I want to be able >to do this under Windows 98!! Does anyone know if that is >even possible, let alone how it could be done? I don't know the specifics of RT-11s requirements for the CD. I expect that RT-11 sees it as though it were a hard disk of exactly that many blocks (well 4 times the number of CD blocks because of the 2048<->512 byte thing). Many (many) years ago when I used an LSI-11/23 under RT-11, we had a 40MB drive that emulated 4 RL02 drives (or some such). I don't recall if this was done in software or hardware - quite possibly it was a software driver that came with the disk. Why is 212992 magic? What do you do to make this CD visible as 7 (or whatever) disks under RT-11? Essentially your CD is a stream of N 2048 blocks and is presumably seen by RT-11 as such (at a sufficiently low level) and then given meaning by some software layer. A typical method for generating a layout with both ISO and "other stuff" in logically separate areas of the CD would be to start by generating a binary ISO-format file with just the ISO data in. The first 64 2048-byte blocks (or is it 32?) are ignored by the ISO9660 standard - they are deliberately not used. Now create an empty image file, the size of your CD. Overlay the ISO image file onto this. Now you slip the PDP-11 boot block in there and add whatever else you need at the end in whatever format you want. The ISO file structure will be unaffected (so long as you tack things on after its logical end). What you need to find out is RT-11s requirements in this area. Actually doing this under W98 may not be that easy. Typically, when I've done CDs that have both ISO9660 and ODS-2 on them, I've generated the image on OpenVMS and burned the image to CD using a PC.

Well, assuming you really mean DA15 (not DB15 :-)) then, yes, all you need is a transceiver. The miniature type that fits straight onto the AUI connector is best, and usually cheap and easy to find.

>Does anyone else have copies of the RSX-11 set of 2 CDs? At one point the RSX, TOPS and RT11 CDs were all available as binary images. I know I downloaded all of them and burned them to CD with no problems. (Well, maybe a slight issue with the RT11 one IIRC - I used W98 and whatever burning software I used was not too happy verifying it ... seemed usable though). Tim does not seem to have any problems with people downloading large amounts of data so rather than ask for a CD, just burn one. Antonio

You are probably thinking of "ex". But "ed" is a proper subset of "ex". The classic answer to the question "point me to a guide" is $ man ed executed on any Unix or Unix-like system. If you don't have one of those running, you can try, with your favorite web browser, a Google search with the key words: unix man ed carl

Info on Bill Godbout

by bobbeleh＠earthlink.net

Hi I'm new to this forum and I'm looking for info on contacting Bill Godbout. I worked for him and Mike Quinn back in the early/mid 70s, testing ICs in the back room of Quinn's. Any help would be appreciated.

Anyone Care About RT-11

by IVIE＠cc.usu.edu

> Even if you don't have any bugs to contribute, please comment > if you think a central location is a good idea so that everyone > who uses RT-11 can be aware of the current list of bugs. FWIW, I think a central bug listing is a good idea. Caveat on my opinion: I do not currently have any PDP-11s operational, although I have several that could, conceivably, be put into working condition on short order. I.e., I'm not currently running RT-11, although it's on my List of Things to Do. Roger Ivie ivie(a)cc.usu.edu

Very Old Texas Instruments IC's

by rigdonj＠cfl.rr.com

I found a TI data book dated 1971 and it doesn't even mention 12xx ICs. It appears that by 1971 TI had switched entirely to the 54/74xx series.

Getting Unix to run on a PDP-11/34

by hans＠Huebner.ORG

Hi, this weekend, we have been unsuccessful trying to get one of the ancient Unix versions (V6 or V7) to run on a PDP-11/34. The plan is to have an ancient PDP-11 on the VCFe in Munich running a proper version of Unix. THe machine has two RK05 drives, RX01 floppy and a TS03 tape drive. Our first problem is that we have been unable to find or make up a TS03 bootstrap. We considered using RT-11 to transfer disk images to RK05 drives, but we could not figure out how to get the image straight to the disk without having to store it in an intermediate file and writing a RT-11 program to access the disk sector-by-sector. We have a lot of hardware at our disposal, so we took a Emulex TC12 Pertec tape controller from a 11/44 (the 11/44 would also be nice as demonstration CPU, but it has a SMD disk controller for which we have no drives). Not having any documentation on the TC12 we just put it into the 11/34, but it did not work (bus error LED lit). So we're kind of stuck. Any ideas, hints or pointers (especially to a TC12 print set) would be greatly appreciated. Thanks, Hans -- finger hans(a)huebner.org for details

TTL computing

by Lee.Davison＠merlincommunications.com

The point is, I can't see a real difference between a ROM chip and a decoder + gates. Electronically they're much the same thing. Physically, to change the program, I have to use a soldering iron. It is _not_ clear to me why one is called firmware and the other called hardware. How about .. Hardware is the physical part(s) of a design that can be seen, touched, crushed, thrown, weighed etc. Firmware is the idea statically implemented in that hardware.

HP 88780 / 7980XC Interface Question

by fmc＠reanimators.org

"Douglas H. Quebbeman" <dquebbeman(a)acm.org> wrote: > I see lots of references to these drives... > > Do they possess multiple interfaces, or do you get > one that has the interface you need? You get one that has the interface you need, but I think you can swap interfaces; e.g. I've swapped a single-ended SCSI interface board into one that I got with a differential SCSI interface. Note that the interface board is screwed to the back plate which has the cutout for the connector, so if you get a different interface board you may also want to get the appropriate back plate for it. > I've seen one with an HP-GPIB interface connector > on the back, and was wondering if I pull that rear > cover off, will I find a set of Pertect interface > connectors hiding there? Or is that simply a different > model? I haven't looked inside one with a Pertec interface, but the SCSI interfaces expect to plug into a flat cable that is in the base of the drive and I expect the Pertec interface would too. There's also a four-slot card cage in the right side of the drive, accessible by removing a top cover. The boards installed in this cage make a difference too. Later drives have only three cards installed (the read/write/PLL boards and formatter board were replaced by a single board). 7980A and 7980XC are HP-IB-interface drives sold into the HP minicomputer markets. The XC suffix means the drive was sold with a variant board that supports data compression (meaning you can write tapes that are only readable by other 7980XCs). 7980S is the same drive with a SCSI (single-ended I think) interface, sold into the HP minicomputer market. At one point HP offered a field upgrade kit to change your HP-IB drive to a SCSI drive. There is also a variant board that supports 800 BPI (in addition to 1600 and 6250). I believe that 800 BPI and XC compression are mutually exclusive (you can't have one drive that does both). 7979A is an HP-IB-interface flavor of the drive that supports neither 6250 BPI nor data compression. I'm not sure but this may simply be a different-variant board as well. 88780 are drives sold outside the HP minicomputer markets, including OEMs like IBM, Sun, and Tandem. Of course the OEMs came up with their own model numbers. I have some notes that say data compression was option 400 and 800 BPI was option 800, but I'm not sure whether this applied to a 7980 or 88780. -Frank McConnell

I've used it under Solaris. That depends on what he meant by "make ISO images of cd roms." I read that to mean "I want to make a raw copy of the disk, and I'm just saying ISO out of habit." You obviously read it to mean "I want to make an ISO image out of some files I've got so that I can burn it onto a CD." So which was it?

No; assuming you've got files on a Linux filesystem, you use mkisofs to create the ISO9660 image file (with Rockbridge extensions). Then you use cdrecord to burn the image onto the CD. To capture an existing CD-ROM into an image file, most likely, Chris is correct, but I haven't gone that direction yet. -dq -Douglas Hurst Quebbeman (DougQ at ixnayamspayIgLou.com) [Call me "Doug"] Surgically excise the pig-latin from my e-mail address in order to reply "The large print giveth, and the small print taketh away." -Tom Waits

should I take RM03's ?

by GOOI＠oce.nl

Hi all. I need some advise. In 3 weeks time Edward and I drive to Italy (some 1100 km) to pick up several PDP-11/70 parts. I have the oppertunity to drag 2 RM03 massbus drives and some packs back home. Now I know already that these drives weigh about 200 kilo, have a disk capacity of 67 Mb and are really power-hungry: at 240 V/50 Hz. stand-by is 3.5 A. running they consume 11.5 A. and rush-in current is 22 A. My experience is that DEC tend to give high numbers for the power consumption, but do these drives eat that much current? Are they worth preserving? Or should I leave them where they are? Next to the 11/70 is looks great (IMHO) but I would love to hear some opinions from other collectors. - Henk.

HP 88780 / 7980XC Interface Question

I see lots of references to these drives... Do they possess multiple interfaces, or do you get one that has the interface you need?

Or is that simply a different model?

Dear ClassicComper's. I've a HP9845b, which run for a long time, but now it's dead. I think, it's caused by the powersupply, because there are no voltages to be measured at its testpoints. Does someony has experiences in reparing this powersupply, or much better some schematics. Greetings from Germany Andreas

I have (finally) received my first piece of Big Iron but it has death of the 2.5v PSU, and all the PSU bricks were removed and handed to me before I could note their positions.

I thought about setting them flat against a board and using the small (half-inch long) "glass tube" inline fuses. If I can get those to smoke the glass dramatically enough when they blow, it would be easy to replace the blown parts with fresh fuses for a new program. Not to mention that it may be fun to be able to re-arrange the fuses ;) Chris Christopher Smith, Perl Developer Amdocs - Champaign, IL /usr/bin/perl -e ' print((~"\x95\xc4\xe3"^"Just Another Perl Hacker.")."\x08!\n"); '

Half on, half off -- New CD-R drive and 512-byte blocks

by csmith＠amdocs.com

Hi everybody. This isn't strictly on topic, but I think the intent of the question makes it close enough. I just bought a new CD-RW drive -- a Sony CRX145s -- and am curious about whether it may read the 512-byte blocks necessary for using it as a backup boot device on my VAXen, Sparc, SGI, etc. Does anyone know whether this, or just for information, some other CD-RW unit, will do such a thing? Note that I do know that discs are written in 2048 byte blocks, and the answer won't affect its performance in writing disks on these systems. I am also aware that doing this for the long term may needlessly shorten the life of the drive. As I said above, it is more for curiosity, and eventually I would like to know that in case my RRD42 dies, I have a backup. :) Chris Christopher Smith, Perl Developer Amdocs - Champaign, IL /usr/bin/perl -e ' print((~"\x95\xc4\xe3"^"Just Another Perl Hacker.")."\x08!\n"); '

It doesn't get more simple than this. You used to be able to get registered EPROMs; using those, the state and output registers are built into the EPROM and all you have to do is wire it up. And write a grundle of microcode, of course... The Firefox QBUS Adapter was implemented this way. Some of the outputs ran back around to control a mux to select which input was being examined by the microcode for a given state. Hmm, I'm going to have to turn your drawing sideways, I think: > INPUTS > ||| > ||| > VVV > +----------->\MUX/ > |+-------+ | > || | | > || V V > || +--------------+ > || | ROM | > || +--------------+ > || | ||| > || V VVV > || [State and Output reg] > || | ||| > |+--------+ ||| > +----------------+|| > || > VV > OUTPUTS Since this was done using registered PROMs, the only parts are ROMs and the mux. And a synchro register for inputs; I don't recall whether I synchronized the inputs before or after the mux. Am I the only person who sees registered SRAMs intended for cache and things "Hey! A huge microcode store that can run really fast!"? Some of them even have JTAG inputs you could use to load the microcode. Fundamentally, a state machine consists of inputs, outputs, a state register, and a next state decoder. A microcoded system just uses a ROM for the next state decoder. Roger Ivie ivie(a)cc.usu.edu

New MV-II boots! And, of course, Questions....

by doc＠mdrconsult.com

I'm quite tickled. Also inordinately proud of myself (for figuring out the BA23's slightly different connections & stuff and not letting loose any Magic Smoke). First thing: Thanks, Terry! I really like it. Terry's rackmount MicroVAX II has been condensed into a single BA23. For the nonce, I'm running a single RD54 and a TK50 on their respective controllers, and a DELQA ethernet board. The KA655-A with 32M is a LOT faster than the KA630 with 13M. The TK50 is slow as ever.... I was hoping the BA23 would be quieter than the BA123. It's not. Questions: Does the KA655 CPU make this a MV-3800, a MV-III, or a MV-II with a KA655? Terry, looks like you were right: The memory board, which is a DataRAM 63016 C0. Listed online as a 16M board some places and 32M others. The system sees it as 2 16M boards. Is this kosher? The 3-position CPU-RAM ribbon cable is plugged at one end and at the middle connector. Does it matter? I'd _really_ like to run the RX50 instead of the TK50. Unfortunately, I don't have a cable. Can a PC floppy cable be modified to work? It looks like, from reading past posts, connecting on the "B" connector - i.e. no twist - ought to do the trick. Not quite brave enough to just plug it in and see. Last (not really applicable in the BA23), I see references to terminating the last RD5x on an RQDX3. Is that termination effected at the distribution board (M9058 in the BA123) or on the drive? Drive 1 and Drive 2 don't look any different. Which may be why they're, um, terminally off-line. Doc P.S. - I've always wanted to say "For the nonce"....

Decitek 262 info wanted...

by jos.mar＠bluewin.ch

I obtained a cheap (10 USD) Decitek papertape reader from Ebay. ( A tip for those who believe that to be impossible : try .de instead of .com ) However it has a seemingly exploded IC on it : IC "I" below R5 and R4, has had it top half blown off..... Anybody with a similar reader could look up what kind of IC it was ? And if anyone has the pinning for this reader handy... I just saw that Decitek still exists. Do they react kindly to hobbyists ?

some items sorta conspired to drive cpus to multiples of 8bits.

Does anyone have a live VT52?

by celigne＠celigne.freeserve.co.uk

Does anyone have a live VT52 to hand? I'm working on a patch for xterm, and I have a query about its behaviour that could be answered by having someone type five characters in local mode and reporting the results. Unfortunately my VT52 is dead and I haven't spent the time to discover why, yet. I promise that these five characters won't kill yours!

Yes - and I doubt that the VT52 emulator makes *any* attempt at emulating the VT52 quirks. In fact, it's quite possible that noone knew all the VT52 quirks and so the VSRM may have required only adherence to the published VT52 information (which admittedly may have had internal-use-only enhancements). When I wrote that VT102 emulator, way back when, the customer for whom we were implementing it had requested VT103 emulation on the basis that it was a higher number than VT102 and so must be better. I never saw one in real life but the manual documented it as a VT100 + LSI bus (no, I did not implement the LSI bus ...). I suppose I should just count myslef lucky that they didn't happen to know about the VT105 or VT125 or VT131/VT132! Antonio

I have a V20 PC-XT in working order. Do you still have those tools. I'd like to try out CP/M on it. IIRC, the German c't magazine once had such tools. Back then I already had this V20 PC-XT, but didn't want to mess with CP/M. After just having made the transition from C64 to PC (MS-DOS), CP/M was "old stuff" back then :-) regards, chris

It's early days for me on NeXTs, so I don't know a whole lot about the development environment yet :-) Looking at the developer docs on channelu I got thinking that since the libraries are already there all I *really* need to start hacking about are the usual cc/ld/gdb tools (I could live without make, ar, nm etc) and the includes for the APIs. In theory I should be able to make all of these myself - I've got lots of versions of the GNU tools source lying around, it should be easy to build 68k versions of the ones I need, and I could cobble the includes together on an "as needed" basis using the developer docs and example code on the net as a starting point. Painful, but - here's the question - possible? Al.

I went in over lunch to see what was new/old, and discovered they are closing for inventory for a few weeks, but when they reopen in May, they will only be open one day a week. The idea is that they will post stuff to a web page so you can see what's worth a trip down on the single day they do business. The guys who work there seem to think that management doesn't understand that stuff won't flow out as fast and they'll have a backlog. They figure the new hours will last as long as the floor space does. In the meantime, they had PowerMac 6100s for $5, 7100s for $10-$15 (I left them there; already have a 6100; just got an AV monitor from them for $5) I also saw a couple of A-sized HP pen plotters, a bunch of free 14" VGA monitors (probably to clear them out before inventory) and the usual desks and IBM Selectric typewriters and $10 laser printers. I did pick up a few things... Tektronix 502A dual-beam scope *with* Tek tilt cart Heath ES-600 function generator (q. 2) DEST PC SCAN 2000 (free) NEC Multisync 2A (free) (would have been two, but the second one let out the magic smoke). Apple 20MB SCSI drive (old Mac or late Apple II) Misc Sun SCSI, video and serial cables (free - being a regular customer has its benefits, like knowing they allow you to take a dip into the large box of assorted cables when purchasing items (no sign above the box); they don't require a one-to-one match-up of cables to items, so I get a lot of Mac and Sun goodies that way. They just don't want to price the cables or keep them with the items for sale, so they all go in a big box if they are not attached to things). I must have missed some SGI stuff - they had a couple of SGI keyboards on the keyboard shelf. Their new hours are going to be a pain.

AS/400 and DATA General Stuff

by jrkeys＠concentric.net

At a auction today I was able to get a IBM AS/400 Advanced 36 for $37.50 but no terminal or keyboard with it. The black case is in pretty good shape and it powers on and gives a number code in the little reader on the front of the case. Got a Data General terminal model 5220 but no keyboard was it for 6.99 at a thrift. At the auction a also got Tandy VMT monitor and IBM mono monitor both for free. Got a MAC (128) kb and mouse both in the designer boxes with their foam containers. This is better good since someone jut paid over $500 for these same type of boxes with nothing in them on eBay. I got both for $4.98 at the thrift.

Looking carefully I see that it has 5 pairs of configuration jumper pins. Three for setting the SCSI ID, one for termination, and one "test block do not jumper".

Half on, half off -- New CD-R drive and 512-byte blocks

If it's an IDE type, you'll probably best forget it. I should have mentioned that -- it's SCSI, of course. > However, I'm not a CD-RW fan because of the media cost. BEGIN off-topic-moment The only reason I'm particularly interested in the RW capability of this drive is for some experimentation with Linux on a Sega Dreamcast. I have it booting from CD-R, but if the Dreamcast will use an RW disc, it may save me money and coasters in the long-run. END off-topic-moment Perhaps it may also be useful for transferring data between two systems with these drives (...or mine is an external, so the drive could be carried), in the absence of a better removable media solution. I must admit that last time I saw them, they were megabyte-per-megabyte cheaper than any other common re-useable removable storage. > If the drive manufacturer can profide the command set and you > can figure out > how to create a driver for it for the target environment, you > can do what you > want.

I think that I should have been clearer here too -- what I'm wondering is not whether it will work with the environment, since I'm sure that cdrecord will compile and drive it in nearly any environment I'm likely to need. The question is -- in the case of my other drives going out, would it be possible to use this drive as the primary boot device for one of these systems. That, of course, requires the slightly odd (for a CD) block-size. It's likely that I'll just plug it into the VAX and try booting VMS from it -- that would answer the question pretty quickly. :) I was just hoping that somebody knew right off...

need the use of a scanner with sheet feeder (near Seattle if possible)

Sheet-fed scanner for most stuff, he does use a hand-scanner for bound stuff. Like Eric, I'm pretty sure he does most pages as 600dpi line art. I just got doing the same for a section of a CDC manual that's in hot demand; then used Kodak Imaging to create a multi-page TIF from the individual TIF pages. Then print to PDF using Adobe Acrobat 4.05's PDF Writer. Yields a 367kb PDF, whereas multipage TIF was 2.1MB. > I don't see any taint on mine -- all the holes look the same > shape to me.

DWBUA woes

Judging by the diags I see for the XMI<->BI equivalent widget, my guess is the diags do something like: "test I can see the VAXBI side", "play with the VAXBI side a little", "test I can see the UNIBUS side", "do data transfers". Since that's roughly the order the tests are numbered in for the XMI widget, if the same logical sequence is true for the VAXBI widget, I would guess that 0E means an "earlier" test failure that 12. >Anyone with any substantial DWBUA experience? Not me. I never broke mine :-) >I have the tech manual, Is it scanned - it may help :-) >but in the past, I just plugged it in >and it worked. Didn't have to >go at it step-by-step. Remind me what processor you are running this on. A Scoprio of some kind IIRC? Which backplane: 12 slot or 24 slot VAXBI? What exactly do you have in which slots of the VAXBI? The 8200 Owner's and Installation Guides are available at: http://208.190.133.204/decimages/moremanuals.htm (or they will be when it comes back up ...) Nothing obvious leaps out at me from the Installation Guide. There is a bit in bold that means "plug the cables into the M7166 the right way round, and mind they are delicate". There's another bit that says M7166 in first slot, UET in last slot and grant cards all the way along. And another bit that says "don't snag the cables when closing the UNIBUS cab" It doesn't say "make sure the four cables go to the right places" but the diagram on p4-28 shows how they should go. The DWBUA needs a transition header installed (but I presume you would not even have got this far into the tests without one!) Finally it says read the Tech Manual if the T1010 yellow LED does not light!! Antonio

DWBUA woes

by erd_6502＠yahoo.com

So... the 8200/DWBUA saga continues... I got a replacement T1010 module. It passes internal tests unlike its predecessor. It does not pass all diagnostics (no yellow LED). The two error codes I see in GPR0 (General Purpose Register 0) are 12 and E. Code 12 means that the DWBUA could not cause the M9313 UET to respond to an interrupt cycle. Code E is a register-communications issue. The DWBUA won't pass diags unless an extensive set of conditions are met, including full communication with the UET. Before anyone asks, there is nothing on the Unibus except the UET and a full boat of double-grant cards. At this point, I suspect the DD11DK, the M9313 UET and/or the cables. I have three M9313 modules. One consistently generates a 12, two generate an E. What's not clear to me is if the tests are performed in numerical order - i.e., the "12" UET is working "better" than the two "E" UETs. I cannot guarantee that any of the UETs are fully functional. I have no Unibus VAXen (out of storage and set up) to test an M9313. I could set up an 11/04 to tweak at the registers, but that's simple CSR poking, not full diagnostics. If there's anything related to XXDP and a UET, I guess I could try that (I'd have to either dig out my RUX50 or get XXDP onto 8" floppy somehow, unless I can get it on an RL01 or RL02 pack - I have an RL02 and RL11 right here). Anyone with any substantial DWBUA experience? I have the tech manual, but in the past, I just plugged it in and it worked. Didn't have to go at it step-by-step. Ideas? Source of working UETs?

NeXTstep 3.3 minimal developer setup

by alan.pearson＠cramer.com

I'm looking into ways of setting up a "poor mans 3.3 developer toolkit" up on a NeXT slab which currently has 3.3 user installed on a 100Mb hard disk. Before I get too into the idea I thought I'd better ask if anyone on the list has already tried and failed :-) I'm guessing that all I *really* need are the includes - the libraries are already installed, and IIRC I can cross-compile GNU tools on a Linux box (any idea what versions of compiler etc were supplied with 3.3 Developer?). I'm happy to archive apps to floppy to free up a bit more space if required. Any thoughts, NeXT fans on the list? I know it's probably easier to trawl for a copy of 3.3 Developer and just install a bigger hard disk, but this way seems a bit more fun :-) TIA Al.

probing HP-IB devices on the HP-IPC

by vp＠mcs.drexel.edu

Hi, For those of you following the saga of my attempts to resurrect my HP-IPC here is the latest update. I have managed to create diskettes that the IPC can read by using an original 720kb PC compatible diskette drive and original double density diskettes. I used OpenBSD (any Unix-like system should also work) and the command dd if=IPC-IMAGE of=/dev/rfd0c to copy the images I downloaded >from the network to the floppy. Although some of the images did not work first time (and OpenBSD refuses to write to IPC formatted diskettes) I eventually managed to get most of the usefull files to IPC formatted diskettes (by going through the IPC). My next step is to see how to address HP-IB peripherals from the ROM BASIC. I tried to use the following Series 80 program from the SERIES 80 HP-IB Interface Owner's Manual Original program: 10 S=7 @ ! Variabe S is select code 20 SET TIMEOUT S;500 30 ON TIMEOUT S GOTO 100 40 FOR I=0 TO 31 50 DISP "SPOLL DEVICE # ";I 60 S1=SPOLL(S*100+I) 70 PRINT "DEVICE ";I;" PRESENT" * 80 NEXT I 90 STOP * 100 ABORTIO 7 110 PRINT "DEVICE ";I;" NOT PRESENT" 120 GOTO 80 130 END To get it to run on the IPC I added the following 2 lines 12 MASS STORAGE IS "/dev" 14 ASSIGN 7 TO "hpib" Now the program runs but reports all 32 devices as present(!) I only have an HP-9122D dual diskette drive at address 1 and an external printer at address 5. Any clues? Thanks **vp
