Hello, folks -- My first computer, a portable Sharp PC 4502, needs a substitute battery, now that its original Yuasa battery is no longer manufactured. Other batteries exist almost identical in power specifications, but not in dimensions. The Yuasa battery had the following specifications: NP4.2-6H 6V, 4.2Ah -- dimensions: 1 7/8" x 2" x 4 5/8"; sealed lead-acid. The AC adaptor (which still works fine, luckily) has the following specifications: IN: 120V AC 60Hz 23 W; OUT: 10V DC 1.2A. (The computer has two 720k floppy drives, no hard drive, a back-lighted 640x200 LCD screen, V20 CPU clocked at 7.11 MHz, and the only peripheral I've used with it is my Okidata ML 182 Turbo 9-pin printer that I still share with three other computers on a data switch. I bought this computer in 1989 through DAMARK when it was already close to being obsolete; it was manufactured around 1987.) I still have the original dead battery, and it's stamped with 8710281 on its side; the second (nearly identical) Yuasa battery is stamped with 9410211, and I'm barely able to keep it charged for any meaningful length of time anymore. Does anyone know of a suitable substitute battery that would satisfy the above specifications? This has been a very interesting machine from an important era in pioneer portable computers that I think would be worthwhile preserving in working condition. Although I can run the machine with its AC adaptor, it would be a pain to keep that constantly plugged in to avoid the setup screen that pops up when turned on without a battery (and always have to reset everything). And it would be odd, too, to have an oversized battery connected to it from outside of its case, and inconvenient (to say the least). Thank you for any suggestions!

Netbooting Apollo Domain [34]x00

by obsidian＠panokratie.de

Hi! Does anybody have information about how the Apollo Domain xx00 series goes about netbooting? I didn't recognize any standard boot protocol... Is it possible to teach it to user BOOTP/TFTP/RARP stuff or maybe the HP remote boot thingies? Thanks, Kevin

Rescue of Four Phase Systems mini-computer from Tampa (long)

by xds_sigma7＠hotmail.com

Blech, brown recluses! I have a computer that was a home for them... My uncle lives in Colorado Springs, and his old house had a seperate, free-standing shed/garage type of thing (much too big for a shed really). Anyway, that's where he kept his tractor, camper, etc. And his garage was infested with the things... And back in the far corner was my Honeywell DPS-6/54, and the previous owner had thoughtfully coiled up the cables in the bottom of the cabinet, creating a nice hiding space.. Needless to say, my uncle and I were wearing thick gloves and long shirts when we put it in the truck..

Offering HP 200LX palmtop

by azog＠azog.org

This is not necessarily off-topic, because the device is interesting enough to qualify, even tho it is less than 5 years old. I recently picked up an HP 200LX "palm-top". This is discontinued from HP, in favor of their PocketPC products, but the details can be had at http://www.hp.com/jornada/products/200/. In short, this is a palm-sized PC, with a slightly-less-than 8MHz 80186 processor, 2mb of RAM, and embedded DOS. It has your slew of familiar PIM type apps - calendar, contacts. It also has an embedded version of Quicken and cc:Mail. It has a PCMCIA controller, but I dunno what devices it supports. I tried a Lucent WaveLAN 803.11b Silver card in it, but, as I suspected, it did not work. According to HP docs, you can use flash-ram, modems, and other devices. I have the recharger, but it's fitted with alkaline batteries right now. You'd obviously need NiCad to use the recharger unit. Includes a fairly thick users guide. I'm offering it here first, just because I find it a "gee-whiz" type of device, if not exactly "classic". If no-one here is interested, I'll try to offer it on e-bay. It works, except I get error messages that the backup battery is low, even tho I replaced it. Perhaps something is wrong? I'll trade it for pretty much anything of interest (but I'd really like a VAX 750 :) so let me know please.

ID a keyboard please ?

by lgwalker＠look.ca

I usually pick up any old uncommon keyboard that I see. I recently acquired one that has no Logo or company name on it. Opening it up gives some #s and the name Handaman on the PCB. The connector is a right-angle 5pin DIN. It has a plastic silver-gray case and a metal bottom-plate It is qwerty with grey and black keys. There is a reset button on the upper-left side. There's a row of 5 function keys on the left labelled PF1 to PF10. On either side of the space key are LOCK on left side and GRAPH on right side. On the left side of the qwerty are ESC, a tab-key,CTRL, and SHIFT. It has the >< keys between the l-shift and Z.and double periods and commas where those usually are. Some others are also differently placed- INS/DEL are one key. It has a numeric keypad with a RED break key and a double 0 next to the regularly placed 0. Anyone recognize this beast ? thanks larry Reply to: lgwalker(a)look.ca

computers in movies

by jim＠calico.litterbox.com

I was just watching CircuitryMan the other day on cable. Amusing to find that even in the distant future when jacking into someone's brain is common place and the environment has been so despoiled as to be uninhabitable (and we get the environmental lecture from Plughead, the bad guy) that the tools the police use to scan someone's brain for information are driven by a Kaypro 2. :) -- Jim Strickland jim(a)DIESPAMMERSCUMcalico.litterbox.com ----------------------------------------------------------------------- BeOS Powered! -----------------------------------------------------------------------
