I'd probably use Veroboard and a "wiring pen". I bodged one using an expired
Berol "Handwriting" pen (the red things), a chunk of thick copper wire from
one of the cores in an offcut of mains wiring cable (the stuff that's
designed to go inside walls) and a small reel of "Roadrunner" green 38swg
enamelled copper wire. The tip is the standard Berol tip, drilled out with a
0.8mm tungsten carbide drill bit. Much fun.
I think I got the idea from one of the pages on <
http://www.elm-chan.org/>;
plenty of good stuff on there, even if most of it is in Japanese.

Microcontrollers. See <
http://www.microchip.com/>. I use them a lot - they
make nice little protocol converters, LED flashers, basically anything that
doesn't need to do a great deal of high speed numbercrunching. Yes, the
banks/pages/locations architecture is a bit of a pig, but it's not (that) bad
once you get used to it.
Now, if anyone REALLY wants to flame me, I used a GAL in my "pre-prototype"
6502 computer (really just an LED chaser thing that could do basic math). A
GAL as in "generic array logic", a reprogrammable PLD. Well, it saved laying
out half a dozen 74LS chips on the breadboard 8^)
Later.
