I just used ROMzap to load 4K of code into a 16F877. It took 23 seconds
via the serial port.

ROMzap also has a Turbo Mode and can dramatically reduce the
re-programming time. For example if you change only 1 ROM word, a normal
programmer will reprogram the entire chip. ROmzap will only reprogram
the changed word and this process takes milli seconds.

Turbo mode won't work that fast if you add or subtract words near the
start of the code space. In that case the ROM past the first changed
address will have to be reprogrammed.
