************************************************************
The device has active high(!) SO strobes triggered by
- read accesses, which transfer data from the the 8 SI
- lines to the bus. Logically SO0-7 and SI0-7 ought to
- be hooked up to the same input matrix, but this only
- appears to be the case with the Astrocade home systems.
- The arcade games instead channel the SI inputs through
- a quartet of MC14539B (pin-compatible with 74153) CMOS
- multiplexers and connect the SO strobes to unrelated
- outputs which generally use the upper 8 address bits
- as data.
