Absolutely!

1. The width of the board is largely determined by a row of IC's located at
both ends of a 40 pin, dual row .1" spacing socket for additional boards
with that finger stock pattern on the end. IOW the old, 30 year old, stuff
has to fit it, which determines the length of the socket.
2. The length is largely determined by there being 8 such sockets, spaced
on a nominally 1" grid because that is the thickness of the cartridge case
that contains these boards. Traces are thin now, and isolation cuts are
about .004" now, so it just isn't practical to think of a shrink unless we
redo every accessory board ever made for the old girl. As a hobbiest
effort, the cost of that to the potential user makes that a non-starter.
So how much do they charge per sq inch?
They can't work from eagles .brd files?
I'll see if I can get some answers from their site tomorrow late. I have
to put a fresh regulator and brushes in the GMC's alternator tomorrow,
after 120k miles something is getting funkity, I would have today but 2+"
of precip changed my mind for me.
Thanks for the name Jon.
Cheers, Gene
