[Ham-Computers] Re ISA and PCI Slots

[KD7JYK DM09]

I am measuring slots now.

I have a motherboard with two types of ISA plugs.  One is about three and a
quarter inches long, the other about five and a half inches long.

A PCI plug is also about three and a quarter inches long, the same as one
type of ISA plug.

A PCI card has a much higher electrical contact density, about three times
that of an ISA.  If you have two to compare, you will be able to feel the
difference.

Trying to determine a type of card by bay length is near impossible as an
ISA card can occupy space in the computer from about three inches up to
eighteen inches for a full size card.  I do not know the physical
limitations of PCI type cards.  As to which is which in what kind of
computer as determined by age or operating system, I have a relatively new
motherboard with several of each type of slot.  What you get is more
determined by what the manufacturer put on it than anything else.
