That might be a good idea Mark, all us wannabe design engineers would have 
to have a couple of those just to play with if the price was reasonable. 
(there I go again, thinking like a retired old fart on SS, which I am 
these days)  Throw out a price & we'll see if its reasonable.

I especially like the gold card edge as I was the one who got tired of my 
mpi being so intermittent, sawed the 'solder plated' nose off it, and 
sawed the edge off a plated pc card, tacking it in place with a 3% silver 
bearing solder as the bridgeing from the mpi board to that.  Now the only 
intermittent connection is those grounding clips at the end of the side 
port socket.  If I was still using it for the workhorse machine, I expect 
I'd have figured out a way to cannibalize some gold-plated ground plane 
pieces big enough for the ears and did the same thing with the those, & 
maybe even had the clips plated.  I did go so far as ask a jeweler for a 
quote once, but its $ has faded into history now.

But its the shoemakers kids story, I'm not using it daily anymore, which is 
damnation with faint praise for first a full blown big box amiga, and now 
linux on an Athlon XP2800 & a gig of ram in the fastest box & nearly 500Gb 
of drives in 3 boxes.

Actually, such a kit, with gold plated clips and edge/ear  patterns, just 
might be something you could sell to frustrated by bad connections mpi 
users.  I've got another later mpi I'd love to so convert.  There's a 
potential sale of that for every cart the shack ever sold, not just the 
mpi's.  Unforch it will also test the users skill and soldering tools, so 
theres a potential to sell the conversion being done by you since not all 
of the users are fluent in hot solder.
