> I just sold 30# of aluminum heatsink approx 8" wide x 4" high x 5' long for > $40.00. 9 other identical pieces were scrapped out for about $15.00 each. My > understanding is that they were in the $100.00 + catagory when new. And that sounds like it was for stock extrusions. If you add all sorts of machining so the heatsink actually touches the processor, you can add a bunch more on to the price. Fans are cheap and effective. And the last place *anyone* wants to go is liquid cooling. -- Will

WTD: Copy of CD from "Programming Psion Computers"

by classiccmp＠philpem.me.uk

Hi guys, Does anyone happen to have a copy of "Programming Psion Computers" by Leigh Edwards (published by EMCC Software) sitting on the bookshelf? I've just bought a copy, complete with CD.... but the good ol' Royal Mail have managed to snap the CD clean in two. An ISO image or CD-R copy would be most useful... The publisher has gone bust, and I haven't managed to find any trace of the author either :( Thanks, -- Phil. classiccmp at philpem.me.uk http://www.philpem.me.uk/

Dumping an Intel D8749?

by derschjo＠mail.msu.edu

Short story: Anyone have the ability to dump an Intel D8749 microcontroller's internal EEPROM for me? Long story: I picked up a neat-o keen display unit. (See http://yahozna.dyndns.org/scratch/avtron/IMG_0477.JPG for a picture) It uses two *huge* Panaplex displays (Babcock SP-431's) showing 4 7-segment digits (with 2" digit height) each. It's made by Avtron, an industrial automation hardware company -- I got in touch with their support department and they helped me identify the display (it's a "K885 Extrabrite display" designed to be used with their K885 "Speed / Draw" systems). Alas, they can't provide any interface specifications (which is about what I expected), so all I know is that it uses some sort of two-pin serial interface (with connectors labeled "High" and "Low") I was thinking that if I could get a dump of the microcontroller ROM, I might be able to either (a) decipher the protocol enough to allow another microcontroller/PC to control the display, or (b) decipher the hardware enough to figure out how to write a replacement EEPROM for the onboard microcontroller... I think this thing would make a *really* cool clock... - Josh

Missed an auction... most annoying...

by wh.sudbrink＠verizon.net

In case anyone on the list won this ebay auction: http://cgi.ebay.com/ws/eBayISAPI.dll?ViewItem&item=360303684042&ssPageName=… and doesn't know what that little thin rectangular board with the caps, resistors and coax on it is, it is an original Software Tech Music System board. The docs and software for it are on Jim Battle's Sol website. Not much to it electronically, but I really wanted an original. Rats!
