you can accomplish rudimentary masking and etching by using cheap packing tape.
Encapsulate the board then slice and remove portions of the board you'd like to etch
away. No copper sulfate IIRC (the etchant) won't eat your fingers. Just DON'T pour
it down the drain, protect your clothes and be careful of animals.
(and if you do etch your own board, it's non-trivial
to gold plate it).
Well plating can be accomplished in the home shop but where are you going to get the
gold. Wait for a meteorite?
But it brings up an interesting idea of mine. Couldn't you reverse plate the gold
right off of pins and whatnot? No nasty chemicals, no mess, no fuss.
it is, however, quite easy to get header plugs of
various sizes, including ones with wire-wrap pins.
If I ahd to make such an adapter in a hurry (== no time to make the
PCB)_, I'd probably put 34 pin and 50 pin wire-wrap headers ont a bit of
square pad board, wire-wrap approrpraity, and fit one of said adapterso
nto the 34 pin header to conenct to the edge connector on the cable.
If I'm following you, couldn't you cut the card edge from a busted drive, solder
that to an appropriate board (I would have to assume the spacing is identical), solder a
header connector, preferably right angle, to the opposite side of the board, then solder
jumper wires where appropriate?
