Check http://home.hetnet.nl/~tshaj Click on the 11/35 console. Click on the uPDP-11/93 link. There is a simple page about the 11/93. The only interesting part (?) is the description if the DIP switches. That's all I have on the 11/93. - Henk. > -----Original Message----- > From: Doc Shipley [mailto:doc@mdrconsult.com] > Sent: vrijdag 12 april 2002 4:45 > To: Classic Computers > Subject: PDP-11/93 Console Pinout and model rev. > > > Does anyone have the pinout for the db25 console port? > Assuming that > the 25-pin bulkhead connector marked "Console" is a serial > console port? > Also, I understand that a M8981-AA is a 2M board and a -BA is a 4M > board.

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. The only reason I didn't get one instead of the Sony drive I finally settled on was that they didn't answer my email, and I really didn't feel like playing telephone games trying to find the right number ;) Chris Christopher Smith, Perl Developer Amdocs - Champaign, IL /usr/bin/perl -e ' print((~"\x95\xc4\xe3"^"Just Another Perl Hacker.")."\x08!\n"); '

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.

While it's possible that he's a bit put off being called 'Tom' instead of 'Tim', which is his name, I doubt it...

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.

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
