Central Processing Unit Circuit Card.
The CPU (MC 6800) card contains the
microprocessor and RAMs with associated IC chips to control the digitizing
operation.
h. ASR-33 Teletypewriter.
The teletypewriter receives the digitizing
information via the TTY interface circuit card for the printing of information and
for punching of the numeric control tape.
The ASR-33 teletypewriter used with the
Model 102K only receives information.
3-3.3 DSP Machine Controll
dedicated microprocessor
functions.
It consists of
er.
The DSP machine controller contains a machine
with interfaces to control the various automate drafting
two basic units:
Operator Console
Controller Cabinet
a.
Operator Console.
The operator’s console is microprocessor controlled and is
designed in a keyboard fashion.
It has a full set of alphanumeric ASCII characters
plus eight additional machine function keys.
These keys are used to program
drafting information or can be used to override the punched tape program (paragraph
3-4.1).
A 16 digit alphanumeric display shows all operator’s entries or shows
present machine status.
(1) The keyboard on the operator panel can be used to directly control the
movement of the X and Y carriage system and provides for the input of manual
drafting commands.
(2) The operator console
controller with a single cable
is freely movable and is connected to the machine
and uses a RS232C serial interface.
