Data Monitor. This equipment consists of the data decoder
part of the 13 channel PCM decoder BA1/S, with four extra
units to enable it to give a teletext-type display of the
status of the data part of a 13 channel PCM coder BA1/4.
Power requirements +28 V at 60 mA, -16 V at 80 mA, +9V at
4A. 3U CDX frame. Sub-units UN26/23, UN26/24, 0027/9,

Single-step and Breakpoint Monitor. This unit forms part
of the Designs Department Z80 bus system (ZEUS). It
moni tors the microprocessor's address bus and asserts a
non-maskab1e interrupt when a predetermined address is
detected. In conjunction with suitable software, this
allows single-stepping of, or insertion of a breakpoint in,
a user's program. It is designed to be mounted immediately
to the right of a UN26/31 CPU, behind the (A-width) front
panel of this unit. Power requirements +Sv at O.S amps
max. (approx). Short 4U unsupported card with doub1e-
sided S7-way edge connector. DD 1981.
Supervisor. Supervisory equipment for EP1 S/ 42 HF control
system. Two of these equipments are used to monitor the
operation of the EP1S/42 and act as the data network
manager. Power requirements 24V d.c. PN3/S4. Parent
equipment EP1S/42. DD 1984.
HF Station Monitor. Part of the EP1S/42 Rampisham
Transmitter Control System, this equipment provides input
interfacing for 128 digital monitoring points and an IEEE
488 interface to other data gathering equipment. Power
