OK... thanks to one and all for tips... I will probably go with Digikey or
the supplier in Christchurch (since if I order from them, it will arrive on
one of the first flights in October). I do need the thru-hole variety for
this 22-year-old board. The input voltage shouldn't matter - it's a +5V-
only design anyway. I have no +12V or similar to feed it.
