b. Controller Cabinet.
The machine controller is the main unit of the automatic
drafting and scribing operations.
The controller contains a machine dedicated
microprocessor with interfaces needed to control these operations. The controller
houses the FACIT 4031 tape reader which reads the punched tape from the teletype-
writer for automatic drafting/scribing operations, two D100 boards which are the
motor drive circuits for the X and Y carriages, and the pen drive/tangential tool
control circuit board.
The +5 V, ±15 V and +24 V power supplies which provide the
voltage for proper operation of the DSP machine controller are also housed within
the controller cabinet.
