Compaq Portable III fails POST?

by Watzman＠neo.rr.com

I have a Compaq Portable III here, worked the last time it was powered (years ago), may or may not still work. I also have a file called "SP0316.ZIP" that contains "SP0316.exe" which, I THINK, is a utility (service pack) that makes the setup disk for the Portable III. However, it needs to run on a PC with a 360k 5.25" floppy drive. I THINK.

bad keyboard wires

by rtellason＠verizon.net

Just a thought on this subject -- do pretty many of these boxes have that _fuse_ that I've seen mention of in some contexts, which would kill the +5V to the keyboard if the old one had that bad of a cable? Something that may end up needing to consider here, depending o how bad that original cable was. -- Member of the toughest, meanest, deadliest, most unrelenting -- and ablest -- form of life in this section of space, a critter that can be killed but can't be tamed. --Robert A.

Compaq Portable III fails POST?

by spectre＠floodgap.com

I think this one is on-topic. I got a Compaq Portable III dumped on my doorstep (more or less literally, actually), and while I don't really collect PCs, this one's form factor fascinated me. However, it seems like it's failing POST or its equivalent -- when I turn it on, the caps lock light on the keyboard (literally hanging on by a few threads) blinks, then the three lights on the front bezel and the 5.25" floppy light blink three times accompanied by three beeps from what appears to be the power supply?, and it just sits there, doing three beeps pause three beeps pause ..., until I turn it off. Nothing else spins up and nothing shows on the screen, even with me messing with the contrast. Any suggestions, or is there a troubleshooting manual to give me some starting points to see if I can refurbish this? Is the fact that the keyboard is probably incompletely connected to blame? -- --------------------------------- personal: http://www.armory.com/~spectre/ --- Cameron Kaiser * Floodgap Systems * www.floodgap.com * ckaiser at floodgap.com -- Klein bottle for immediate occupancy; inquire within. ----------------------

Anyone have an Apple Modem 1200 or 300 manual?

by darin.lory＠gmail.com

Ray, There is a good list of AT commands at http://docs.kde.org/stable/en/kdenetwork/kppp/appendix-hayes-commands.html The ATI9 will return the Apple product code and firmware version of the modem. Check out http://www.tidbits.com/iskm/modems.html#aa7 for the Apple/Hayes AT commands. -Darin Date: Sat, 19 Aug 2006 13:15:16 -0400 From: Ray Arachelian <ray at arachelian.com> Subject: Anyone have an Apple Modem 1200 or 300 manual? To: cctech at classiccmp.org Message-ID: <44E74724.2040706 at arachelian.com> Content-Type: text/plain; charset=ISO-8859-1 I'm wondering if this was a Hayes compatible modem, and if so what the result strings were for various commands such as just "AT" by itself, and "ATI", "ATI0" and so on.

by dm561＠torfree.net

I'm hoping someone can ID this interesting board (sorry, no pix avail). 16Bit ISA (full-length) DB25S Connector 20pin header socket 10 pos DIP SW 10 seg green LED bar graph 3 sets of jumper pins 80186 CPU 2 x XC2064 XILINX FPGAs Pair of IDC 7130/7140 (1Kx16 dual-port memory) 2 x 256x8 SIPPs C8208 DRAM controller 2 x 27256 EPROMs 2 x DS1225Y BBU SRAM 2 x LH0033 Fast FET buffers (12 pin metal cans) Misc 74LS & F glue chips Nothing recognizable in the EPROMS or SRAMS; 1 EPROM is blank (erased/defective?) Ring any bells with anyone, or time to scrap for parts? mike

Properly. >> > can you elaborate, or point to a web page? thanks I wasn't aware that Intel had anything to do with the AS/400 architecture :-) The iAPX432 was an interesting Intel failure of the '80s which provided the tools to layout subsequent Intel devices. <http://www.brouhaha.com/~eric/retrocomputing/intel/iapx432/> is a good read on the beast.
