I'm working towards that, anyhow.
I was just looking at some smaller PCB's pricing, and I hope you got
a good deal
on the PCB since on the same page they listed the prices for
proto-type multi-layer PCB's.
They an't cheap -- 8 layer board QTY 2 $500 each -- they don't do 7
layer boards.
Price is probably down to $50 when you buy 1000, but this isn't a board
that we could find 1000 customers for at $50 apiece.
It could be a realistic candidate for a two layer board that does the
worst/most repetetive of the busses and power with the holes sized for
wire-wrap sockets. But that's a huge engineering project just to
recreate something, and there'd still be huge amounts of wire wrapping
to perform.
I once in my naive youth bought a 'bare kit' unpopulated PC-XT clone
motherboard (this was from a Canadian company, btw.) It was only a two
layer design, and I never did get it populated. It probably wouldn't
have been stable, with the deficient power and grounding inherent in a
high chip count two layer layout.
(okay, somebodys turn to say it can all be done in an ASIC)
