Components
==========

U1		PIC16LF88, or similar (see below)
Q1, Q2		Generic NPN transistor, e.g. BC337
R1, R2		1k, any tolerance
R3, R4		10k, any tolerance
CONN1		100 mil header, 5 pins
CONN2		DB9 connector, female

If low-voltage operation (down to 2V) is desired, use a 16LF87 or
16LF88. Otherwise (4V or more), a 16F87 or 16F88 will do, too.
The programmer uses no special features but the UART, so it
should be possible to build an equivalent circuit with other
PICs, e.g. a 16F688 (which is smaller, cheaper, and also works
with 2V - and just happens to be missing in my junkyard).
