Controls related: (added by Mirko Mattioli)
=================
When optical wheel is selected (via dipswitch), then gear shift (low/high) is enabled.
On the real PCB the optical wheel encoder is connected to 74LS169 ICs (@A16 and @A17)
via a flip-flop IC mounted in the steering wheel assembly. As a result, the output
of the flip-flop generates a signal that contains the information about the steering
direction; this signal is routed to pin #1 (U/D) at ICs A16 and A17 (high when turn
left and low when turn right). The second signal of the optical encoder goes directly
to pin #2 (CLK) at ICs A16 and A17 and it is a clock for the 74LS169 ICs; this clock
frequency is proportional to the movements of the steering wheel: fast movements
produces a high clock frequency, slow movements a low freq.
PCB: REF.930217
The PCB has a layout that can either use the 4 ROM set of I7, I9, I11 & I13 or larger
ROMs at H8 & H12 for graphics as well as the ability to use different size sound sample
ROMs at C1 & C3
