many types of course. Generally speaking do the materials used in pc's from the 80s fall into a single category? Everything is injected into a mold for sure, from largish cases to tiny keytops. Would all this qualify as polystyrene? Whatever the case, what's a good solvent (not necessarily glue) that's useful for repairing big cracks or splits, to tiny hairline cracks. I say solvent, and some glues can fall into this category, because it makes more sense to reinforce the materials from behind to effect a strong bond, and for cosmetic sake meld the item from the front, to obscure the defect itself. Many surfaces are anything but smooth. Has anyone tried, given they were successful in melding the surface, in reproducing the look of the surface surrounding it? Smooth surfaces can be melded then touched up lightly w/ultra fine emery cloth and some sort of lubricant I would guess. But the rough textures are a different story.

[rescue] Tapes, Drives, Libraries, and Arrays Need to Go (fwd)

by dgriffi＠cs.csubak.edu

If someone would forward this to CC-talk and elsewhere, I'd appreciate it. I am preparing to move soon. I don't know how soon, but it's likely going to be the case that I find something in a neighborhood I want, that I can afford, and that I need to pounce on quickly, so I'm trying to be rid of anything I don't have any hope of ever using. I have a huge cabinet (I think it holds either 300 or 500 reels) of full of 2400ft nine track tapes. I no-longer have a working nine-track drive. This cabinet is about four feet wide, seven feet tall, and two feet deep. This pile o' tapes, the cabinet in which they hang so uselessly, and the non-working DEC SCSI tape drive[0] need to go. I don't want any cash for it or the tapes, just please come and get them. If you only want the drive, I'll deliver it anywhere in Austin, but preference will go to someone who'll pick up the cabinet full of tapes. I also have a Sun StorEdge L3500 tape library with six DLT7000 drives. It is mechanically sound, and the drives work, but there's a defective optointerruptor that determines the X position of the carriage; it's a cheap part to replace and shouldn't take a lot of labor, but I'm backing up to disk now. You may either pick this up, or help me load it and unload it, and I'll drive it to your central Texas location with my truck. Photos of the library are here: http://jonathan.celestrion.net/photos/library/ I also have a Compaq Storageworks BA370 24-slot enclosure with dual controllers. This takes SCSI Storageworks "storage building blocks", and I may actually have enough of them to fill the unit (not necessarily with disks in the blocks). I have spare batteries, controllers, and other bits. Need a fiber switch? I have gigabit Brocade Silkworm and possibly enough GBICs to fill it. Feel free to make an offer on the BA370 or the switch. I'll mail the switch or deliver the BA370 in central Texas, but I won't ship the BA370 anywhere; it's just too hard to crate reasonably. [0] I don't recall the model, but it's vacuum-loading, SCSI, and 5 or 6 rack units tall. The failure mode is that it fails to load the tape (or loads, fails to notice, and then unloads), so hopefully it's just a sticky sensor. -- Jonathan Patschke ( "They don't have the right to read a book out loud."

Open source, stand alone, ASCII terminal project, UPDATE

by bob＠jfcl.com

Back in December I posted about an open source, stand alone ASCII terminal project for old computers - http://www.classiccmp.org/pipermail/cctalk/2008-December/265312.html The VT6, a simplified single host port version, is available now - PC boards, partial kits and full kits of all parts. It was actually available back in March, but the first run of parts sold out just on the Spare Time Gizmos group and I never got a chance to announce it elsewhere. The second, much larger, run of parts is now available and hopefully there should be plenty this time around. The VT6 is a small PC board, about 2.5" by 4", that uses a VGA monitor and a PS/2 keyboard and is able to do pretty much anything a VT220 can. The firmware is about 95% written in C (with about 5% assembler) and is open source and GPL licensed. The tool chain used for development, including the SDCC C compiler, is all free. The microprocessor is flash based and firmware updates can be downloaded from any PC over an ordinary serial port. If you need a terminal, it's just the thing to stick in the back of your classic computer. The hardware for the other version of this terminal, known as the VT5 is also finished and really only needs the firmware to be ready. The VT5 supports multiple host ports and sessions with split screen displays, downloadable fonts and (if we can get the firmware written!) ReGIS and/or Tek 4010 type graphics. The firmware is really the limiting factor for everything (isn't that always the truth??) and we could use help with the programming. There's a Source Forge project for the firmware here - http://vt4.sourceforge.net and the Spare Time Gizmos page for the VT6 parts and PCBs is here - http://www.sparetimegizmos.com/Hardware/VT.htm There's also a manual (unfinished - we could use help with that too!) - http://www.sparetimegizmos.com/Downloads/vt.pdf Bob Armstrong

9-track BOT/EOT markers?

by derschjo＠msu.edu

Hey all -- Got myself an HP 7980S 9-track drive (always wanted a 9-track drive...) and accidentally mangled my one and only 9-track tape just after the BOT marker (not sure what caused it, maybe the drive needs a bit of adjustment...). So I have two questions: Where can I find a reasonable replacement for the marker, and where does it go? I see the sense foil on the part of the tape that got mangled, but I don't know what side of the tape it was originally on... Thanks! Josh P.S. The magical tape autoloading thing this drive does is the coolest thing I've seen in a long time :).

Collection to go in San Antonio, TX - repost, now free/pick-up

by mtapley＠swri.edu

All, My friend John Gold has still got a respectable collection in San Antonio that needs to not be his. Surely somebody with a storage shed and a van wants to come by and collect this? He'd like it to all go at once, and not to the dumpster, but I think you can work with him on partial deals. I think at this point the price is "come get it". John can be contacted at: jhgold at stic.net Sorry to pester y'all again with this, but some of the gear in here really looks to me to be worth preserving, and John hasn't got the space to do it. ---------------- Computers IBM 5324 large old work station/main frame HP Pavilion 7370V IBM Power Server 320 Type 7012 Macintosh Power PC G3 M4405 233MHz w/ keyboard & mouse Apple 3 CompuAdd 212 Model A002 Leading Edge DC-3010 PC Clone Tall Tower Eltech desktop clone PC Clone mini tower CompuAdd 325 Desktop Dell Dimension XPS M200S Dell Optiplex GXi Sanyo MBC 550 NEC Power Mate V466 Toshiba T1000 Laptop (2) w/ parts Toshiba T1000SE Laptop (2) NEC Multi Speed Laptop Laser 128 Laptop/Portable Computer IBM PC single 360K w/ HDD 5150 w/ keyboard IBM AT clone NEC Ready 466ES NEC Power Mate 286 AT&T Complete system w/ monitor & keyboard AT&T Box (2) Model 6300 CPU1Z & CPU2 w/ 1 keyboard Compaq Presario 4550 mini tower Atari 400 w/ Cassette drive 410 IBM PS-2 Model 30 8530-001 IBM PS-2 Model 30 286 8530-U21 Packard Bell Legend 300SX 386SX-16 Compaq Prolinea MT4/66 tower GTE Government systems desktop Gateway P4D-66 Monitors IBM terminal 3151 RS-232 & printer ports (2) Atari SC1224 IBM 8513-001 SVGA Zenith Data Systems ZCM 1450DT IBM 5153 CGA Apple 3 monochrome XTRON RTB Technologies CM147E CompuAdd MCH 4095N (1989) WYSE WY50 terminal w/ keyboard Dell VM1 mono (1990) Samsung MA2565 (1989) Packard Bell PB1272A (1988) Standard MCH4095N (1988) IBM 5081-16 Composite Video (1990) Sysdyne CGA (IBM clone) AES SVGA (1996) Samtron SVGA (1989) IBM Terminal 3164-11 (1992) NEC Multisync XV14 IBM 6405301 Serial monitor in box IBM 3164 serial terminal w/ base CompuAdd SVGA 51086 (1990) Magnavox Computer Monitor 80 video only Visual 120 Serial terminal w/ keyboard NEC MultiSync JC-1401 P3A 13" (1986) NEC MultiSync 3D NEC MultiSync 3V Printers HP Desk Jet 500 Star NX-10 Dot Matrix Panasonic Quiet KX-P2180 Epson LQ570 Dot Matrix Star NX-1000 Multi font w/ box Texas Instruments Microlaser Pro E Epson LQ-1000 Wide Carriage Dot Matrix Qume Daisy Wheel w/ extra wheels and print cartridge Kodak Personal Portable Diconix 180si Miscellaneous IBM Keyboards (5) Canon Personal Copier PC-3 w/toner cartridges Seiko Digitizer Tablets (3) IBM SCSI drives 7204-001, 7207-001, 7210-001 EXABYTE SCSI tape drive CI Designs SCSI peripheral box / in box IBM PC case 5150 IBM XT case 5160 Musek scanner (no photo) Memorex scanner (no photo) IBM Keyboard??, 5015715, in box, never opened BK Precision 2040 CB Signal Generator Arnet serial expansion board, with software and cables HP 1611A Logic State Analyzer for Z80?

VCF East 6.0

by evan＠snarc.net

Hi all, Go here:http://www.vintage.org/2009/east/exhibit.php to register for VCF East 6.0 exhibits. It's okay if you only have a general idea of your exhibit right now. You can always fill in some more details later. However for the VCF's advertising / marketing purposes, it is MUCH better to sign up sooner rather than later! People who sign up sooner will also have dibs on the best booth locations. The event is Sept. 12-13 at the InfoAge Science Center in Wall, New Jersey. We're still in the process of arranging lecturers and special events. Please contact me off-list (evan at snarc.net) with any questions, notes about mistakes in the web site, etc. - Evan (& Sellam)

receptacles (was IBM 029 Keypunch has arrived)

by roger.holmes＠microspot.co.uk

Thanks for the info, "receptacles" got hundred of items, though few seem to be on plates UK style and none in boxes like a UK 'metal clad' socket, but I can cut suitable holes in a few project boxes so not really a problem. There was a splash proof socket in a box but I don't really want a flip up cover on a permanent installation. Thank again.

Emulex SCSI Controllers available...

by lbickley＠bickleywest.com

I was chatting with a DEC broker recently regarding SCSI controllers for DEC gear - when he mentioned that he had a quantity of Emulex UC07's available. UC07's are QBUS cards which have a single SCSI port and support either MSCP or TMSCP (in RT land, that would be either DU or MU devices). The manual states that the UC07 is compatible with RT, RSX, RSTS/E and Ultrix versions which support MSCP or TMSCP. The dealers initial price was high (as expected). However, he then added - "I'd be willing to do better for hobbyists - as long as they commit that the boards will only be used for hobby purposes - and not for commercial use". So here's the "deal": $235 per UC07 plus shipping from Mountain View, CA (FedEx Ground). I've paid MUCH more for SCSI interfaces for my DEC QBUS and UNIBUS systems - so IMHO, this is a great deal. The broker said he did not want to deal "individually with a bunch of hobbyists" - so he asked if I would be willing to consolodate a single order of UC07's to him. I reluctantly said "yes", as this is not my business and I'm not interested in making money on this deal - only covering costs. To get a sense of interest, please reply to me privately if you'd like one or more if these "critters". The manual for the UC07 is available on bitsavers. A link to a bitsavers mirror is below: http://bitsavers.vt100.net/pdf/emulex/UC0751001-F_UC07_Feb90.pdf Regards, Lyle -- Lyle Bickley Bickley Consulting West Inc. http://bickleywest.com "Black holes are where God is dividing by zero"
