Dayton, here I come!

by zmerch＠30below.com

I'm actually going to make it to the Dayton Hamvention this year, taking off Friday morning, for about a 9.5 hour drive... staying until Sunday morning/noonish, I believe. Any good things to see/do/visit/eat/drink whilst I'm there? Thanks, and who knows? Maybe I'll finally meet someone else on the list "like, in person, eh?" ;-) Laterz, Roger "Merch" Merchberger -- Roger "Merch" Merchberger | "Profile, don't speculate." sysadmin, Iceberg Computers | Daniel J.

IEM HP-IB devices (was Cool stuff!)

I have an IEM HP-IB tape drive (a 4400 series). I posted a similar request for info on cctalk a couple of months ago, but nobody responded. My box has an HP-IB to SCSI motherboard and an HP 4.0Gb DAT SCSI tape drive. > [...] It has a LCD > display on and it [...] There are also three buttons on it > marked Select, Next and Previous. Mine has the same panel and buttons. I tried your trick with the select button and it gave me a similar demo (nice trick, thanks). It claims to work with MPE and HPUX and to be compatible with the HP 7978 tape drive (and the C1511 whatever that is). Unfortunately, my Integral PC does not recognize this drive. I suspect that the motherboard for the tape drive is the same as the one in your optical jukebox, but with different ROMs. There is also a DIP switch in the back (for setting HP-IB address and various options) and a bunch of jumpers inside. I have no idea what they are supposed to do. If you want I can take a photo of the motherboard and send it to you. **vp

FA: Collection of Otrona Attache Parts -- Complete System?

by patrick＠vintagecomputermarketplace.com

I collected a number of Otrona parts over the years with the intent of reassembling them into a working system, but that hasn't happened, and I think other interests are going to keep me from ever spending the time it needs. I think almost everything you need to build a basic working system is here. I have the following items available, up at auction on the Vintage Computer Marketplace... http://marketplace.vintage.org/bid.cfm?ad=727 All items are completely and totally untested. Links to photos are on the listing at the link above. * Six CPU boards, "pulls"... Most with parts on them, one bare board. The ones with parts all have some parts missing that I think are relatively easy to find: 765 floppy controller chip, Z80 PIO or SOI, or 5027 video controllers, etc. Only one board has a 5027 on it, but I also have a "loose" 5027 that I will include. I have EPROM images for the CPU board EPROMs. * Three floppy drives loose plus two in their chassis components--the special not-quite-half-height drives the Attache used; * GPIB cards in various states of assembly, rework, or disassembly. I believe there is also an 8086 card, but it's stripped of parts. * Case and chassis parts that I believe are enough to build (or reface) a complete unit, include outside cover, two rear bezels (one with PSU attached to it), a front bezel still wrapped in foam, keyboard shell top and bottom halves, handle; * Additional keyboard assembly, dirty, but usable; plus three keyboards without case. * One video/CRT field replacement unit (tube + boards + mounting hardware), plus an extra video board, extra yoke, and another incomplete video assembly. I think I also have a third partial assembly in a box; if I find it, it will be included. * A number of expansion/daughter cards for 25th line, graphics, and high-res graphics; some are loose, but some are mounted to CPU boards (see photos). * CP/M boot disks in unknown condition (images also available from Don Maslin, I believe). * Binder with schematics.

DEC vt100 terminal stuff / parts available

by jwest＠classiccmp.org

I have 2 VT100 terminals plus a vt100 plastic shell that I'm parting out. They are VERY yellowed cases, obviously a smoking environment. Definitely some screen burnin too. On at least one of them the fasteners that hold the top of the case to the bottom of the case are broken. I don't think they are worth much more than the junk heap. They all power up and go into setup mode just fine. They are all true VT100's, not 102's, etc. Some or all of the keyboards are missing some keycaps. I think one keyboard may have all it's keys. In addition, I have a vt102 without the top or bottom case. It is in perfect working order, clean, and no burnin with one major flaw. The metal band around the front of the tube has slipped, meaning two of the L brackets that are held down by that band have slipped back so the monitor is about 1/2 inch forward of where it should be. Thus it won't fit into a plastic case quite right. The band is too tight to push the L brackets back into place, and I'm not comfortable cutting that band and trying to put a new one in place (something about working with a large glass object under pressure scares me a bit). So far my plan is to keep the vt102 chassis as spares, and ditch the 2.1 vt100's. If anyone wants me to scavenge parts (logic board, power supply board, flyback, transformer, keycaps, crt tube, etc.) I would be happy to do that. Total price for each shipment will be shipping cost + 5 bucks (unless you just want a keycap or something)...negotiable. The only stipulation is you must let me know in a day or two, I'm itching to get them out of the house and gone. Jay West --- [This E-mail scanned for viruses by Declude Virus]

opinions on very long term storage and references from Google search

by msokolov＠ivan.Harhan.ORG

The best long-term storage method I know of is to inscribe the information on a tablet of wet clay and bake it in an oven, after which it becomes hard as rock. Sumerians did this 6000 years ago and their writings are still perfectly readable. MS
