er.,.,. sometimes we get a bit rough. If we get too rough, just tell us.

The 10F200 will be hard to ICSP because every pin is needed for ICSP, and
you'll have to disconnect stuff in order to get it to work (generally 
speaking). I
would start with a higher level device, where the ICSP pins are "extra" 
and won't
interfere with your circuit. At least a 14=pin device, like the PIC16F630.
