Linux-2.6.12-rc2v2.6.12-rc2
Initial git repository build. I'm not bothering with the full history,
even though we have it. We can create a separate "historical" git
archive of that later if we want to, and in the meantime it's about
3.2GB when imported into git - space that would just make the early
git days unnecessarily complicated, when we don't have a lot of good
infrastructure for it.
Let it rip!

66 | These addresses each read a 16 bit register. These in turn | ||
67 | are loaded from the MDAT serial stream and are clocked in on | ||
68 | the rising edge of SCLK. MLD output is used to parallel load | ||
69 | the external parallel-to-serial converter.This in turn is | ||
70 | loaded with the 4 quadrature inputs from each of two game | ||
71 | controller ports (8 total) plus 8 miscellaneous control bits | ||
72 | which are new for LISA and can be read in upper 8 bits of | ||
73 | LISAID. | ||
74 | Register bits are as follows: | ||
75 | Mouse counter usage (pins 1,3 =Yclock, pins 2,4 =Xclock) | ||
76 | |||

80 | |||
81 | 0=LEFT CONTROLLER PAIR, 1=RIGHT CONTROLLER PAIR. | ||
82 | (4 counters total).The bit usage for both left and right | ||
83 | addresses is shown below. Each 6 bit counter (Y7-Y2,X7-X2) is | ||
84 | clocked by 2 of the signals input from the mouse serial | ||
85 | stream. Starting with first bit recived: | ||

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

130 | These addresses each read a pair of 8 bit pot counters. | ||

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