100        These addresses each read a 16 bit register. These in turn
101        are loaded from the MDAT serial stream and are clocked in on
102        the rising edge of SCLK. MLD output is used to parallel load
103        the external parallel-to-serial converter.This in turn is
104        loaded with the 4 quadrature inputs from each of two game
105        controller ports (8 total) plus 8 miscellaneous control bits
106        which are new for LISA and can be read in upper 8 bits of
107        LISAID.

146         Bits 1 and 0 of each counter (Y1-Y0,X1-X0) may be
147         read to determine the state of the related input signal pair.
148         This allows these pins to double as joystick switch inputs.
149         Joystick switch closures can be deciphered as follows:

215         With normal (NTSC or PAL) horiz. line rate, the pots will
216         give a full scale (FF) reading with about 500kohms in one
217         frame time. With proportionally faster horiz line times,
218         the counters will count proportionally faster.
219         This should be noted when doing variable beam displays.
