+
+ These addresses each read a 16 bit register. These in turn
+ are loaded from the MDAT serial stream and are clocked in on
+ the rising edge of SCLK. MLD output is used to parallel load
+ the external parallel-to-serial converter.This in turn is
+ loaded with the 4 quadrature inputs from each of two game
+ controller ports (8 total) plus 8 miscellaneous control bits
+ which are new for LISA and can be read in upper 8 bits of
+ LISAID.
+
+ Register bits are as follows:
+
+ - Mouse counter usage (pins 1,3 =Yclock, pins 2,4 =Xclock)

+ 0=LEFT CONTROLLER PAIR, 1=RIGHT CONTROLLER PAIR.
+ (4 counters total). The bit usage for both left and right
+ addresses is shown below. Each 6 bit counter (Y7-Y2,X7-X2) is
+ clocked by 2 of the signals input from the mouse serial
+ stream. Starting with first bit received:
+

+ | Serial | Bit Name | Description |

+ +--------+----------+-----------------------------------------+
+ | 7 | M1VQ | JOY1DAT Vertical Clock (quadrature) |
+ +--------+----------+-----------------------------------------+
+
+ Bits 1 and 0 of each counter (Y1-Y0,X1-X0) may be
+ read to determine the state of the related input signal pair.
+ This allows these pins to double as joystick switch inputs.
+ Joystick switch closures can be deciphered as follows:

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