A lot of money. However, considering that I paid north of two bucks for
a SN7400 back then it was not outrageous at all. Also, you got a dang
reliable and sturdy computation machine for that and not some flimsy
foil keyboard like with the Sinclair.

ISA won, big time. To this day it is heavily used in industrial
applications and you can buy new PCs with numerous ISA slots. When the
ICT on one of my projects croaked (after humming along for almost 15
years ...) the client simply bought a new ISA-PC and it was humming
again. Except now they have a CD-writer in there which makes backup easier.

PCI isn't used so much in automation. Sometimes, yes, but a lot is still
ISA.

AFAIR they kept it proprietary. That was the cardinal mistake.

Nah, see link above. Most ISA mobos and cards are in the $200-$300
range. Peanuts if that makes a production line stop situation go away.
If someone is really hard-pressed for money they can get stuff from China:
