parallel. It has an
internal memory of 384k bytes for the storage of programs
written in BASIC. These programs can be transferred to the
module either by using an A6GPP/PHP or by using a VT220
compatible terminal.
Up to 8 BASIC programs can be executed concurrently and
independently of the normal sequence program. Real time
clock function and host processor interrupts are standard
features providing user flexibility in creating data
communication and collection capabilities.
