Has anyone had any luck re-inking printer ribbons? I spent a few minutes looking at this Vic 1525 printer that I got the other day - turned out that the carriage was just gummed up and there was a blown fuse in the PSU section (probably related to the former problem). Of course the ribbon is completely dried out. I'd originally intended for the printer to be a static "Hey, that looks neat" item, but looking at it briefly, it's a good example of how to make a printer as cheaply as possible, so I'm wondering if there's a way of breathing life back into the ribbon so that it can print again in all it's noisy, glacially-slow glory :-) I don't care if it's not as black as an original ribbon would have been - it just might be nice if it was able to print something legible. cheers Jules

My reasons at the time: - All equipment was pretty much at its minimum value-wise - It could still be priced relatively highly for tax deduction reasons - I was very space constrained, and not using it at the time - I'd just gotten married (see "Spousal unit", in a later post) None of them good enough in hindsight for the value that equipment would have now, either to me or others. Damn - too bad I pawned that old Colt Paterson - I bet it would be worth something by now... ~~ Mark Moulding

IBM PS/2 Model 70 HARD DRIVE NEEDED

by mokuba＠gmail.com

Got a hard down situation and need to re-install/recreate the BBS system I had running. HDD makes swishy noises when shaken, haven't tried stirring yet. I /guess/ a bootable MCA SCSI card would work too... ;) I had the 160MB drive, but anything above 30 would work - i guess i'll just have to use a SCSI Drive for the file storage area once i get an MCA SCSI card .... -- Gary G.

WTB: PDP-11/03 front bezel

by pontus＠Update.UU.SE

Hi It's a longshot. But recently I aquired two BA11-N. One is just the cage and power supply. Looks just like this: http://www.ricomputermuseum.org/_/rsrc/1300059803599/Home/equipment/dec-pdp… The other came with mounting box but no front panel. I would like to make it complete with the white front bezel seen here: http://hampage.hu/pdp11/kepek/11-03.jpg Does anyone have one for sale? The greyish plastic arround the front panel would be a bonus since mine got a small crack in it. Regards, Pontus.

Another apple II+ repair

by terry＠webweavers.co.nz

For anyone interested, here's another repair writeup. I didn't keep as good a notes as I should have on this one and the memory (my memory!) is of little help. If I'm going write these things up I really should do it straight afterwards! Anyway, the board lives now. It's something I could never have diagnosed just from chip swapping. http://www.classic-computers.org.nz/blog/2015-12-05-repairing-an-appleII+-b… I did learn that it's possible for the machine to boot to BASIC even with faulty RAM in the first row, something that I didn't think was possible. Depends on the nature of the fault I guess. Terry (Tez)

The Structure of SYSTEM/360 (Blaauw & Brooks, et al.)

by pbirkel＠gmail.com

This was the five-part seminal description of the S/360, published in the IBM Systems Journal, Volume 3, Number 2. I've very much like to read all five parts. Does anyone have a copy that might be shared? Thank you, paul

Among the things that I have given away (to Goodwill, or possibly Salvation Army) - all in running condition: - A complete HP-1000 system: A600 processor with internal hard drive, serial card + 8-port serial mux, all floppies, all documentation, a 2631G printer, 7912 13 MB disk drive, and two 2624B terminals - My CP/M "network", with Cromemco Z2-H with two 5 MB hard drives and two 8" floppies, 8-port serial card, connected to three H-19 terminals (the BIOS allowed you to become the console by typing ^C anywhere), HP2648 graphics terminal with tape cartridges, HP 2762 terminal (a re-badged GE Terminet-300), and an H-89 with three external floppies - Ancient SCM TypeTronic system, with the main typewriter console, two 30 CPS optical paper-tape readers, two really nice (re-branded CDC) 30 CPS punches, 2816 main control unit, and 7816 arithmetic unit (with internal fixed-head disk - 9 words plus a buffer, 30 digits/sec transfer rate!) - Abandoned to rust away in a garage: a Teletype KSR-33 with punch and reader, of course, and a built-in modem with acoustic coupler, in perfect condition - Turned down - a complete HP-3000 system, with two Eagle 76936 512 MB drives, 32 serial ports, 2617A 600 LPM printer, and a few 2640 and 2622 terminals Did I mention that *everything* was in perfect working condition? I'm going to go shoot myself now. ~~ Mark Moulding

> From: Brent Hilpert > I threw out a print-only selectric a few years ago ... Regret it now, > just because it would have been fun to figure it out. C'est la vie. I can top that. MIT offered me (as a gift) the PDP-11/45 that I used to run; it included a pair of CalComp 50MB drives, a pair of RK05s, an ABLE ENABLE, 3 H960's, lots of other goodies. I blew it off, I was too busy dealing with other things at the time (I was on the IESG at that point) to deal with arranging to get it shipped down to me. They gave it to someone else, and near as I can work out, eventually it got scrapped. Every time I think about it I kick myself... Sigh! Although I suspect a lot of people here have stories like that... Noel
