one of the boards i recently got from barry had all 6 reeds, resistors, diode, qc on it. missing was the chip, trimmer, sc, and one complete digit. i soldered in a chip from one of the other pieces, put the power to it and it lit right up. with the old original qc. one of the segment transistors was not soldered down good so i was missing a segment. before replacing the transistor, i pushed down on it and the segment lit up[trick i learned from jeff t], so i resoldered it down. now everything works except i am missing the far left digit. among all my stuff i have numerous single digits of the dot type. installed one of them and now i have all 4 digits.
. next will be the trimmer and it should be done. workers can still be put together from barry's stuff. thx. barry. i think tho' he may not have any mkII's left. all i have are mkI parts. i think jeff has had the same experience. anyway i do not have a dot display mkI up until now so i am quite happy. peter
