=== I/O Port Summary ===
F8F5h - R - read sync signal (bit0)
F9F5h - W - reset 10bit config value to zero
FAF5h - R - read capture data (after capture was invoked and completed)
FBF5h - W - invoke capture
=== Dotclock ===
The dotclock (horizontal resolution) is unknown. For a CPC-like aspect ratio, it ''should'' be 4MHz (for 320 pixel resolution), which could be obtained from expansion port. However, the digitizer includes it's own crystal (the photo isn't clear there, it ''looks'' like 5MHz or 6MHz) (but more probably it's something like 16MHz, the leading "1" being invisible on the photo, 16MHz would be reasonable for splitting a 4MHz dotclock into 4 steps).
