ANN: liblpfk (IBM LPFK driver library), tumble-0.33-philpem1

by classiccmp＠philpem.me.uk

Hi guys, A few of you might remember the IBM LPFK bulk-order a couple of years back, and the ensuing chaos of figuring out the control protocol (which was eventually resolved when Michael Brutman found some old IBM protocol docs which covered the LPFK). I figure I've been sitting on the code for long enough: it's time to make a proper release! Anyone who wants to have a play with this is welcome to do so: the code is on my website, under "Code :: liblpfk", or if you'd prefer a direct link: http://www.philpem.me.uk/code/liblpfk/ I've also uploaded my fork of Eric Smith's "tumble" utility, a TIFF-to-PDF converter. I found a couple of bugs (which haven't been fixed seven months later) and figured it was a shame not to share the patches. After all, it is open-source :) URL for that is http://www.philpem.me.uk/code/ -- click "Tumble". At some point I'll give this a separate page instead of just linking to the version-control repository, and may well document the control file format (which IIRC isn't documented at the moment). Somewhat offtopic, but I've also released a driver for one of the Brother P-touch label printers. I needed labels for my spare parts boxes and really didn't feel like making them with a Dymo gun when I had a perfectly good stock database (which is next on the 'stuff to release' list) which I could use as a data source for said labels. Work smarter not harder and all that ;) These were written for Linux, but should work decently well on BSD too. Forget running them on Windows unless you want to port the serial-line (liblpfk) and/or usb-lp (libptouch) stuff across... I didn't (this be a Linux-only ship, yarrr!) Comments, criticism and so on should be sent to the address below. Sensible patches are, as always, gratefully received 8^) FYI: I'm working on getting a copyright release from university for the DiscFerret software. At the moment most of the Department of Computer Science is on holiday so this is proving somewhat difficult... PCB design is still ongoing, though a lack of funds means it might be a while before I get prototype PCBs made. I'm hoping to release the firmware, microcode and decoder engine under the GPL or LGPL, and the hardware access library will most likely be distributed under a "BSD-with-attribution" type license (I forget, is that 3-clause or 4-clause?). Either way, it'll be GPL-compatible (for obvious reasons!) and commercial-use-allowed. Thanks, -- Phil. classiccmp at philpem.me.uk http://www.philpem.me.uk/

To scrap or not to scrap?

by hachti＠hachti.de

Hi, just followed the thread about ENIAC pieces and went to the website announcing a VCF southeast. There I saw announced sales of Arcnet and Token Ring adapters. That was the inspiration for this posting. * I came across a box of Token Ring and Arcnet stuff. Mostly NICs. * IBM PC AT and around * Sun Ultra 1 (or 5?) pizza boxes * 5.25" and 8" disk floppy drives and HDDs * Philips P4500 computer (or 5400?) Is there any interest in that kind of stuff? Might that be of sufficient quality (quantity isn't the problem) for a dedicated flea market event? Opinions very welcome. And btw I'm talking about stuff in Northern Germany... Regards, Philipp

Data General 6050 Disk Drive

by marvin＠west.net

Oops, I guess everyones esp is not working so well having to ask where this unit is :). It is located in Santa Barbara, CA. I received an email almost immediately from someone interested. If he ends up not taking it, I'll repost to the list. Thanks! Marvin

Data General 6050 Disk Drive

by marvin＠west.net

A friend of mine has a Data General Model 6050 Disk Drive with no disk packs. This thing is fairly heavy (guessing 80 - 100 pounds) and appears to be complete although the top cover screws have been removed and it looks like it might have hit something (the front panel is somewhat bent.) Anyone interested? I can disassemble or whatever to reduce shipping costs. I think he would be happy with around $50.00, or maybe slightly less. Thanks! Marvin

PDP-11/44 mystery card

by pontus＠Update.UU.SE

Hi I've acquired two PDP-11/44 and have just now gone throught the list of cards in the cpu-boxes and the spares. Here is a list: http://www.update.uu.se/~pontus/slask/11-44-kort.txt Nothing special, I've used the field guide to identify most cards. I've only marked one card of each kind. There is two cards connected with ribbon cables that I can't identify. They are made by Data Management Labs in San Jose and are labled DML 750 Board A and Board B. There are some numbers as well (in no particular order) 980-8043 710-1921-001 There are some bitslice chips and a whole bunch of roms. Anything that rings a bell with anyone? Also I wonder what the "M7251 KG11-A U Network interface XOR and CRC block check option" "M3110 DRCSA U Protocol assist #1 w/special character check and CRC (DEC/DLC/DRCSA)" "M3111 DRCSA U Protocol assist #2 w/special character check and CRC (DEC/DLC/DRCSA)" are used for? Cheers, Pontus

OT? Tek 4014 emulator (tying Xterm to ttyS0)

by classiccmp＠philpem.me.uk

Hi guys, I'm building some hardware that spits out debug info on a regular basis, and I figured it'd be useful to have this data graphed on-screen. Making it keep track of the last "N" samples and draw them wouldn't be hard, except adding an LCD display is out of the question (takes up too many I/O pins). On the other hand, I have a perfectly good serial port which runs at a decent rate of speed (115200 baud), and Xterm can emulate a Tektronix 4014 vector terminal. Perfect... except I can't see an easy way to tie Xterm to a serial port instead of having it run an application. There's nothing in the manpage (admittedly I haven't read it all, just grepped it for a few obvious terms) and 'apropos' isn't finding anything useful. I've been told that tip(1) on BSD will do what I want, I just can't find anything similar on Linux... Thanks, -- Phil. classiccmp at philpem.me.uk http://www.philpem.me.uk/

DG 800/1200 questions

by jwest＠classiccmp.org

First on my bench will be a bunch (8 or so) of Data General 800/1200 machines and a few Nova 2's. I can think of several questions so far to get me started down the path: 1) A number of the 1200 machines have broken front panel toggle switches (the switch handle was broken off and lost). Some are spring return to center, some are just two position. Before I take the approach of robbing one of the machines for front panel switches, is there someplace that I can purchase exactly idential (both electrically and cosmetically) switches, or does some one have donor switches available for trade? I am a stickler for completely identical parts, especially for front panel switches :) I was hoping someone had been down this road before and knew the switch model #'s, etc. 2) I have quite a number (maybe around six or seven) of rackmount dual cassette tape units for these machines. I seem to recall that they use cassette tapes that are not identical to the standard common audio cassettes available today. Is anyone aware of where these special tapes can be purchased new? 3) With these machines I got a very large (several crates) library of cassette tapes as well as paper tapes, most appeared to be DG software rather than user data/backups. Are we pretty sure that most software for these machines has been archived somewhere, or should I send these tapes off to Al et. al. to have them read and saved for posterity before I put them in a questionable drive? As old as these tapes are, I wouldn't be suprised if one read was all they will allow. 4) Like #3 above, I have maybe 8 or 10 accounting storage boxes full of schematics & docs for all the circuit cards for the cpu's, interfaces, and peripherals mentioned above. I don't know what the current state of the DG archival project is. Is it likely that all these docs are already archived somewhere? Thanks in advance for any sage advice! Best, J

Mispronouncing acronyms

The cop car terminals looked pretty slick for 1980. Almost like mobile PLATO terminals with their orange plasma display. Maybe it was an actual Motorola product? Of course Motorola and PLATO were also suburban Chicago/Illinois tie-ins :-). And the mall that gets destroyed, I have been told, was (previous to being a mall) one of the Teletype factories in Skokie. Tim.
