[Coco] OT: electronics question

[James Dessart]

I've got a 7402 I pulled from a board. I hooked it up to a 5v source 
and ground. When I sample the inputs, I get a lowish voltage (around 2 
volts, unconnected pins), but when I sample the output, regardless of 
how I drive the inputs, I get a really, really low voltage. Do I need 
to do something in particular to drive the inputs? I'm simply using a 
switch to vcc right now. Should I set it up with the switches 
triggering transistors?

It could be burned out, I used a butane torch to take it off the board. 
It's pretty thick PCB, and I can't seem to get the chips off any other 
way.
