Timings different? My video card was always held on a tight rein to support the monitor :-/. There's a Radeon 7000 (mine) and Nivida 'Peeforce'(form the dump), and funniest of all at this stage, another Nivida belonging to the other kid who has just paid €400 for a box without _any_ trappings (Monitor, mouse, hd, keyboard).

I no longer count a smpsu as a challenge, because they throw on a chip (uPC494 or MC33068), transistor, diode, inductor, and the odd electrolytic and they just work - they _hardly_ever_ blow. Some boards have 5 and I have to point them out to people, they are so small. The board with the sits (remember those?) has + and - 7.5V from 48V or 80V with up to 400V load dumps. Use the uPC494 (or TL494), a fet (e.g. IRFP450), a diode (schottky if you're brave), 150 - 330uH, and a capacitor. That's their recipe - all voltages, all currents. Or you could just buy a heater transformer - there must be 220V around somewhere. They use the MC33068 for 15V - 5V, btw. -- With best Regards, Declan Moriarty. -- Author: Declan Moriarty INET: [EMAIL PROTECTED] Fat City Hosting, San Diego, California -- http://www.fatcity.com --------------------------------------------------------------------- To REMOVE yourself from this mailing list, send an E-Mail message to: [EMAIL PROTECTED] (note EXACT spelling of 'ListGuru') and in the message BODY, include a line containing: UNSUB CHIPDIR-L (or the name of mailing list you want to be removed from).
