Jim,

thanks very much for the offer (creative piece of re-use there, too!) but
RJ's got it... they have the damnedest connectors. It's funny, too, because
most of the engineering on these beasts, while simple, is tough, and these
connectors just aren't. (Mine doesn't have flying leads, it has slots that
allow a connector that looks like a modified femal spade lug connector to
slide in and make contact on a solder trace along the edge of the slot.
Dodgy. I think I may have to photograph it and put it up on my page...)

Happy Trakking, all

No ,they do not have anything that nice. Just edge on connectors, similar 
to
a female spade terminal, on flying leads. No plug at all. My remedy is a
trip to Radio Shack®, to purchase Molex® connectors, and solder flying 
leads
on the PC board.You  then have a secure connection, easier to disassemble,
with less chance of damaging the already fragile board. Did that to my E-20
CA, after it's edge connector went splittsville.
