Hi. There is a guy selling an odd ASR-33 called the "IBM 5028 Operator Station". There was an ebay auction: #190289859981 But it didn't sell. If anyone is interested, the guys email is in the second of the two (short) threads about it here: http://www.vintage-computer.com/vcforum/showthread.php?t=14491 http://www.vintage-computer.com/vcforum/showthread.php?t=14643 Cheers, Pontus.

3B2 install tape woes (or: Wangtek 5125ES docs/jumper info)

by derschjo＠mail.msu.edu

Hi all-- Had a random desire to get my 3B2/600G running again over the weekend (this machine was the first computer I ever used UNIX on, for better or for worse...) after finding a working 300MB CDC Wren SCSI drive for it. (The UNIX install media for this machine only supports a very limited selection of drives -- it's possible to get the machine booting from an unsupported drive, but it requires having a running UNIX on a supported drive first, as far as I know.) Unfortunately, disaster struck halfway through the installation -- the tape drive's roller turned to mush. I checked it out before running the install and it seemed fine -- it was a solid rubber wheel -- but I guess something about actually running it caused it to break down. I managed to fix the roller, but the tape got goo all over it and despite my best efforts at cleaning it, that section of tape is unreadable so I can't reinstall. Fortunately, I have backups of the UNIX install tape files on my PC (several versions thereof, in fact)-- so you'd think it'd be a simple matter of attaching the tape drive to the PC and dd'ing over the files... but I'm not having any luck on any of the machines I've tried. I can only manage to copy over one file; attempting to write subsequent files fails. I have a failing drive w/a partial UNIX install for the 3b2 that boots about half the time, so I tried to do the same from the 3B2 w/this drive installed and it has the same problem writing >1 file, so it looks to be an issue with the drive and not the controller/OS. The drive is a Wangtek 5125ES, a 125MB (or 120MB, if you believe AT&Ts docs) drive. The error I get on from my Linux PC: dd: writing /dev/nst0: Input/output error st0: Current: sense key: Medium error Additional sense: Filemark detected Info fld=0x1 st0: Error on write filemark (I've of course tried different tapes, with the same result.) This is of course the only drive I have that's capable of writing tapes in this format, and of course the 3B2 isn't happy with any other tape drive I have... Anyone have any jumper settings for this drive? Anyone experienced this problem? Thanks, Josh

A trip to the bay area

by pat＠computer-refuge.org

I'm going to be making a trip with a friend out to San Francisco, leaving this weekend for a few days, and am still looking for things to do. I've already figured out the obvious (visit CHM, some surplus places, some hiking), and was wondering if anyone had any ideas, or had a collection of big iron to show off while I'm there. :) Pat -- Purdue University Research Computing --- http://www.rcac.purdue.edu/ The Computer Refuge --- http://computer-refuge.org

is it possible to rebuild old c64 hardware enhancements?

---------------Original Message: Date: Fri, 6 Mar 2009 10:56:44 -0500 (EST) From: der Mouse <mouse at Rodents-Montreal.ORG> Subject: Re: is it possible to rebuild old c64 hardware enhancements? >>> Why are you so intent on STEALING from anybody that you can't >>> easily find? >> Copyright violation - even if that's what this is, a poin ton which >> I am deliberately not chipping in - is not theft. [...] > Ooh, another fun battle. :) Heh. Actually, in an attempt to forestall a reaction I've had when making that point in other places: I didn't say there was nothing wrong with it; I said it is not theft, and that using language based on equating the two merely further confuses an already confused area. (The reaction I'm trying to forestall is the "oh, so you think there's nothing wrong with [...sketch of copyright violation, usually further conflating it with theft...], hmm?" one.) Mouse --------------Reply: It's not just theft; apparently copying a piece of software is equivalent to hijacking a tanker off the coast of Somalia, holding it and the crew for millions in ransom, perhaps killing a few along the way, etc., or the older images of slashing cutlasses, raping and pillaging, etc. No doubt the same punishment will soon apply... m ****

Which is ok in my book (in many instances 20+ year old code is also ok in my book). But you're not suggesting recently developed code should fall into the same category?

Punched cards (Was: 1" paper tape buy ?

by dm561＠torfree.net

--------------Original Message: Date: Wed, 4 Mar 2009 14:39:41 -0800 (PST) From: Fred Cisin <cisin at xenosoft.com> Subject: Punched cards (Was: 1" paper tape buy ? Does anybody object to changing the subject line? My father used to claim that the only reason for existence of the round-hole, 90, 96 column cards was that IBM patented the particular rectangular shape of their holes. He also claimed that IBM patented the whole idea of using a brass roller for card reading, and that that ALMOST worked to cripple the rest of the industry, until somebody finally got photocell card reading working. --------------Reply: IBM did indeed patent the rectangular holes used in their 80 column cards. Whether the brass roller was a major factor is questionable; after all, their competitors also used punched cards. But there's no question that the general acceptance of IBM's card format and their locked-in customers were instrumental in IBM becoming the giant that they did; while their competitiors struggled during and after the depression, punch card sales helped IBM survive and grow. As late as the mid-fifties punch card sales represented 30% of IBM's bottom line; see: http://www.cbi.umn.edu/hostedpublications/pdf/IBMRochesterHistory.pdf mike

Wow! RP06 on Ebay

Actually, two RP06 and one RP07 ran on Magica (one of our 11/70) a little more than 10 years ago. AIDA (2060) ran with one RP07 and three RP06 until 19 years ago. CARMEN (2060) ran with one RP07 and one RP06 until 15 years ago. All the hardware is still around, but only the 11/70 sees some action these days, and then with RA90 disks (as you know ;-) ). I would think that the disk drives and packs are still fine, but we should probably be a bit careful when/if starting them up.
