The data sheet in PDF format is not available, I managed to obtain an old copy
and have scanned it in - sorry about the quality! The original character set
is missing from my copy so I interrogated the chip and produced an excel file
as a "Font table".

PCBs are available at £8.00 each.
A kit of parts is available which includes all PCB mounted components - please email me for information.
I will post any corrections / or modifications here.
In the published article I list SK1 as an 8 pin socket, this is incorrect; it should be a 6 pin mini DIN. The part numbers below are correct.
Q2 the mosfet may be replaced with a standard NPN transistor, for example a BC548. If using a BC548 fit straight in to the PCB without twisting the legs about with emitter to ground. Making this modification will spoil the sync tips slightly but no problems are apparent in operation.
