Parallel Portion of the Card
The parallel portion of the card provides a parallel port to attach
devices that accept eight bits of parallel data at standard TIL
levels. It includes programmable printer control such as: automatic
initialization, printer select, auto linefeed, and data strobe.
Parallel Jumpers
There is one parallel jumper block on the HP24540A card. The
physical jumper block represents two jumpers. The address select
depends on the jumper configuration. One jumper selects the
address and the other jumper selects the interrupt being used.
The following diagram shows the port selection by placing a
jumper cap over the appropriate pins.
