a voltage regulator with 2 pins (is it 2 or 3 pin)?
perhaps the 2 components are the same... diode / resistor?
one mounted horizontaly, one verticaly one needs to be jumperd the
other pins, different brands, different spacing?
please tell me which codes are on the parts? T1? F1? A1?
and again: trace the pcb - where does it start - where does it ends @U1?
X1/X2 is this a quartz? switch? jumper?
does the "jumper"@ the left side of the pcb just determines:
M3simply or R4 "hardware found" ?
