I have terribly fond memories of them... I just let Doug Gwyn beat me on one of the 9764? (the larger 300MB drive that's somewhat similar) on e-Bay... thx, -dq

>What's an LED flashlight? Do you mean one of thelaser pointers? No, they now make flashlights that rather than using a traditional incandescent bulb, use a super bright LED instead. I have one on my keychain that is this tiny thin black plastic thing. You squeeze it, and the LED on the end lights up. It is REALLY freaking bright (bright enough, that if I shine it out a car window, I can read house numbers across the street), and is powered by two fairly standard replaceable button cell batteries. -chris <http://www.mythtech.net>

Yeah, there is the old 7400 series arithmetic unit... But in my experience, most pre-micro computer equipment used fusible-link ROMs for truth-tables; a transitional item, the Processor Tech SOL's keyboard, is a good example of this. -dq

One of the two I bought was still under 3 year warranty! it's a 486slc class machine and uses a thinkpad floppy drive and 2.5 IDE laptop hard drive. nice and quiet too. takes 16meg max. OS/2 runs fine on it, just like it would on any PS/2 or you can use win 3.1. -- DB Young www.nothingtodo.org
