There was a mention of a Pennine Radio set in The Radiophile magazine a
few months back. I assume it's somewhat related :-).

Err, you could always get the purchaser/constructor to drill his own
panel. A large number of kits that I've assembled over the years required
you to do that.
I much prefer thigns to come as kits (toally unsoldered), since then I
can use solder and techniques that have been used for many years and
which I trust, unlike htis lead-free stuff which is certainly not
reliabel if soldered at too low a temperature (which it often seems to be
on commertical boards...)

THis weas an old-ish Epson (An FX-80 or MX-80 or something). It's
actually quite well made. It'll probably end up with an HPIB interface
board in it (which I do have) although I don't have the replacement
firmware ROMs to turn it into an HP82906.

This is a good old-fashioned 9-pin impact matrix printer.
