I figured enough, you can never have perfect voltage control from the PS 
AC/DC converters, but I didn't open my mouth in case I was wrong since I 
don't have any experience with operating RAM at off-nominal voltages ;-) 
Most SS electronics will actually function ok up to at least +/- 0.3 volts, 
in my experience, but they can be temperature dependent if operating at a 
lower voltage than is standard. I've seen electronics boxes work fine in 
ambient conditions and lower than spec voltages, but when you drop the temp 
to some "magic" point, like -15 or -20 C, they cease to operate because some 
component isn't getting enough juice.

What the heck is a "200Meg 512 Meg Ram stick? I assume it's 512 of RAM, but 
why the stupid and confusing name?

The BIOS in my old PC was stored the same way. You had to open the box and 
short out some pins by moving the connector cap to erase the existing BIOS, 
then you flashed the new BIOS to the EEPROM (I *think* it's EEPROM). Very 
scary process the first time you do it!
