    If I wanted to use a MCU or clocked PLD with a protoboard, what would be
    the maximum frequency I could work at without the protoboard's stray
    capacitance mucking things up?

    If I were to use a chip (PIC) that had an internal timer rather than an
    external crystal or ceramic resonator, would I be able to work with higher
    frequencies (> 4MHz)?

    20MHz works? That's great. I was under the impression that if you wanted to
    go higher than 4, you had to use a PWB. That'll save me some money.

    Regularly run 20Mhz PICs on protoboard with no problems. Faster logic and
    the protoboard has been good to 100MHz.
    Analogue stuff is usually OK to say 20-30MHz. It's the wire link
    connections that's the main killer of performance.

    To be clear, we are all talking about

    and not

    Right?

  6. The may be relevant to the postion of your cranial cavity. Located so
    close to your rectum, as opposed to its natural alignment, probably
    causes interference with more than just your machine.
