Doug,

Are you perhaps color blind? < gd&r >

>Years ago, when S100 machines were all the rage, there was a company in Huntington Beach called NNC (No Named Computers *g*). S100 computers took 120 volts in and regulated them down to +5, -5, +12 and -12 volts. Well, if memory serves, it was actually + & - 12 volts at the front end. THis voltage was then passed on the bus to the S100 boards which in turn reduced the voltage down to + & - 5 volts where needed.

>When he'd turn on the computer a very loud BANG! erupt, followed by a voltage regulator screaming across the warehose followed by a huge puff of smoke.

>>This weekend I had my first experience with blowing up a printer.
>>
>>I picked up an Epson FX-880 dot matrix to replace an old one at my brother's newspaper business in Alabama. They still use it for special-format printing needs for their subscription mailing system, and the old printer had lapsed into intermittent beeping, sometimes for up to 10 minutes before printing a few more characters.
>>
>>Late Saturday night I arrived, opened up the box, and found the packing materials crushed, the tractor feed bent, and the case cracked in several places, with small bits of plastic scattered throughout the box.
>>
>>But we had a deadline, so I un-bent the tractor feed, verified that the printer head was movable, and saw no apparent problems, other than cosmetic.
>>
>>I plugged it in, and a few seconds later heard a "snap, crackle, pop" and saw a horrible-smelling puff of smoke come out the back.
>>
>>It was really pretty cool!
>>
>>After swapping the printer to a different computer, we managed to coax (not coax) the old printer into one more print job, which it miraculously completed before reverting into a catatonic state of continuous beeping.
>>
>>Of course, this was the only FX-880 on the shelf at CompUSA, so I'll be back there today demanding that they air-freight an immediate replacement.
