MODEL M2000 (9"—CRT)
GENERAL INFORMATION
The models described herein are fully transistorized (except
CRT) and applicable for displaying alphanumeric charac-
ters. The four models are as follows:
M1000—1SC (Б" CRT)/M2000—1SC (9" CRT) — Oper-
ate with composite video inputs only.
M1000—1ST (5" CRT)/M2000—1ST (9'" CRT) — Oper-
ate with separate TTL level vertical/horizontal sync
and video inputs only.
The CRT'S employed are of the magnetic deflection type
with integral implosion protection.. An operating voltage of
12 volts DC @ 650 mA (typical) is required from an ex-
ternal power supply for the M1000 models. The M2000
models require an external 12 volts DC @ 900 mA (typi-
cal).
Input and output connections for the monitor are made
through a 10—pin edge connector on the signal circuit card.
Inputs consist of video, horizontal/vertical sync, +12 volts
and ground. Output connections are provided for an op-
tional remote brightness control.

MODEL M1000 (5"—CRT)
Two plug—in etched circuit cards are utilized, a signal cir-
cuit card and a deflection circuit card. Components are
mounted on the top of the circuit cards and copper foil on
the bottom. Schematic reference numbers are printed on
the top and bottom of each circuit card to aid in the loca-
tion and identification of components for servicing. All
standard operating/adjustment controls are mounted in a
convenient manner on both circuit cards.
Circuitry consists of four stages for video amplification,
six stages for horizontal/vertical sync and deflection pro-
cessing, and one stage for video blanking during retrace.
The M2000 models also provide dynamic focusing, which is
a function of the horizontal output circuitry.
