    The purple looking chips are ceramic packages, all the black ones are plastic. Looks like the CPU (Or is that a PIA?) on EK is ceramic, and the ROM on Nugent as well. Everything else is plastic.

    Ceramic packages are where the housing for the chip is actually made of a ceramic material.

    I always thought test lead wire was like that on purpose. The extra-thick insulation is there for safety with high voltage circuits measured in the thousands of volts, and the thin conductor acts like like a fusable link to protect against huge amperage spikes.
