addresses controlling character generation for Apology
Caption Generator. Power requirements 5V d.c. CH1/64.
Parent equipment GE8M/1. DD 1978.
Timing Generator. This unit is a modified version of the
GE7/4 and is used to provide the necessary timing pulses
for the GE8M/1 Apology Caption Generator. It will provide
a greater spacing between the caption rows than the GE7/4,
but with a reduced number of rows displayed. Power
requirements +5V d.c. 4U BMM unsupported card. Parent
equipment GE8M/1 and GE8M/504. DD 1980.
