Also, the circuit main boards for scanning electron
microscopes used to be boards over 2ft in width and length. I know
now, that many of those same boards are scaled down to much smaller
sizes to be rack mounted next to other scientific gear in labs.
My brother received one that was determined to be defective
beyond repair from his professor when he was at college for
microprocessor design and engineering at R.I.T. in Rochester, NY. He
unfortunately lost it in his move to Buffalo, NY after he lost
interest in microchips (I know, sacrilege) and took up Linguistics at
SUNY Binghamton, NY and now on to Buffalo University, NY. I think he
still has some various odds and ends, but nothing significant because
of storage (or lack thereof).

I think the largest PCB I've seen is that for the
Whitechapel workstation -
tho' the boards for the Gould 9000 and Honywell L66 come fairly close.
I suppose some old mainframes might have their entire "engineers panel" on
one PCB.
I suspect that very few boards were made that are wider than a standard 19"
rack.
