AT and Baby AT Motherboards – are they still around?
Once the mainstay of Personal Computers in the 80’s and 90’s, AT and Baby AT
motherboards have been left for dead by the average computer user. Even the
technology oriented think of them as nothing more than museum pieces. Yet they
are still around.
In the 1980's and early 1990's, most PC motherboards were AT motherboards.
They only had a large 5 pin DIN connector for connecting a keyboard. All other
ports were supported on the motherboard through headers. Ports like serial and
parallel were available on metal brackets that slid into the slots on the back
of a computer case and were connected to the motherboard headers via cables.
As miniaturization got better, the larger AT motherboards got smaller and were
called Baby AT motherboards.
AT and Baby AT motherboards started with the 80386 CPU's and stayed as a
mainstay through the 80486 and then Pentium CPU's. Some Baby AT motherboards
were made in slot 1 to support Pentium II and some in socket 370 to support
Pentium III CPU's. That's where they pretty much ended.
Are Baby AT motherboards still used? Very much so. There are many legacy
applications in which these AT motherboards are used to run computers that
control expensive machinery. Industrial machines quite often are used for 30 -
40 years or more and while computer technology changes very rapidly, these
machines don't need to re-tool. Such industrial users continue to seek these
legacy motherboards but there are very few vendors left that still stock these
motherboards. Interloper.com is one of the few that does.
