Tall card

<hardware> An expansion card for the IBM PC AT.

These can be larger than IBM PC or IBM PC XT cards because the AT case is bigger.

When IBM introduced the PS/2 model 30 (its last gasp at supporting the ISA) they made the case lower and many industry-standard tall cards wouldn't fit.

This was felt to be a reincarnation of the connector conspiracy, done with less style.

See also short card.
