Re: mini-FAQ: upgrading TransWarp GS/Zip GS
I have all the parts necessary to upgrade my ZipGS, but I have a
question about the crystal. My ZipGS uses a small, squarish "can" for
the crystal, soldered to the board via two pins. It measures about half
a centimeter on each side. There is a circle silkscreened around the
joints. To its left, there is an empty space on the board for a 14-pin
socket. I assume this is for the larger, 4-pin crystal oscillator.
According to Terry Steeper (the dealer from whom I ordered the upgrade
kit), I need to clip off the old two-pin crystal and solder in a socket
and the new 4-pin crystal. There are also 2 surface-mount capacitors
and 1 resistor (or maybe it was two resistors and one capacitor) located
between the 14-pin socket and the 2-pin crystal. These are extremely
tiny and I'm told I need to desolder these (since they are used in
conjunction with the two-pin crystal). If I'm removing the two-pin
crystal anyway, wouldn't it be safe to leave those three components in?
I don't think I would be able to remove them without damaging the board
or the components around it. Suggestions?
