Kits vs ready-made (was RE: Rebirth of IMSAI) - test-drb@ccmp.vtda.org

Your commment below about  production is true enough, but such arrangements
built sloppily will suffer from day-to-day use in an environment where cards
are being move about.  I'd say one should glue the part down and keep the
haywires as short as possible.

By the way, in the aerospace industry, 25 pieces is a long run.  Almost
everything is built in small quantity because you're only building one or
two of those rockets or satellites, and by the time you do it again, the
design requirements have changed.

 The classic example is an IC suspended over a PCB by means of the little
 pieces of #40 wire which connect it to the circuit.  They're not always a 
Well I'd probably stick the IC down to something, and use thicker wire
(stander wire-wrap wire is quite good for this), but I really don't see
the problem with doing this for experimental/prototype circuits, even
ones that are going to be used. I've done it many times and it's never
given any trouble.

   OK, but to use
it repeatedly? . . . 
Well, obviously you don't want to use it in production (far too
labour-intensive), but that should be the only problem if it's properly done.
