Abstract: HYFOC is an extended version of FOCAL-8 to operate the

EAL 580/PDP 8-e system in hybrid mode. It retains all the features of

FOCAL and has additional subroutines to control the 580 computer. The

additional commands are: FDVM - To read and store all the addressable

amplifiers of 580; thus the address selection system provides a sort of

multiplexing. FPST - To change the settings of servo-set potentiometers or

to provide two channel bi-directional DAC output. FSAM - To control

the modes of the 580 computer. FSTR - To store large amount of data in

field one to provide data logging facility. FOCAL-8 user area is undisturbed

as the HYFOC overlay resides in field one.
