The GM812 intelligent! Video Controller card features an
on board Z80A processor fo provide independence of
the host processor and the ability to redefine the
functions and parameters of the display.
Normally used in an 80 x 25 mode the card contains
a programmable character generator allowing
three additional modes of operation — inverse
characters, 1460 x 75 biock graphics, or user
Akeyboard socket allows buffered character
input, and a light pen socketis provided for
specialist applications. Being /O mapped the
card does not occupy any system memory space.
The GM802 RAM board provides a full a
&4K of dynamic memory. The 80 BUS ao
RAMDIS signal istully supported so
ROM in the system is given
priority over the RAM, preventing any
possibility of bus contention. Page
Mode is also supported by the card
which, with the appropriate software,
allows up to four memory boards fo

includes Editor/Assembler; Text Editor!
Pascal and Comal-80. These packages
can also be run under CP/M.
Anumber of manufacturers are busy
working on additional 80-BUS boards
which will progressively increase the
potential of your MultiBoard system.
