capaci ty of 64 kbytes which can be accessed in 8 kbyte
blocks. A bootstrap ROM arrangement works in conjunction
with a dedicated parallel input-output port to support an
intelligent Remex floppy disk drive unit for the purpose of
downloading a CP/M operating system. In addition there are
two serial RS232 ports, a user 8-bit input port and a user
8-bit output port. Power requirements +5 V, 2.5 A. 4 U

CVI Bus Processor Unit. The board is based on an 8085A
microcomputer chip and has edge connections defined by the
CVI Bus. It accepts parallel data in, and reformats to
TELETEXT DATA prior to insertion on TV lines in the field
blanking. Power requirements +5 V, 1 A. 4 U unsupported
board with PNl/29J front panel. Chassis extender CH4/5.
Burn Processor Uni t. This uni t is designed to replace a
number of printed circuit cards, associated with shading
and burn correction, in the Rank Cintel Mk III telecine
machines. It provides improved performance and simplifies
the alignment procedure. The unit accepts the Burn signal
and the three shading correction signals and processes
these to produce Red, Green and Blue correction signals.
Power requirements: t12 V from machine. Chassis: 3 U ISEP
