/* Clock sequence : first try (prototype) */
==== Clock sequence : first try (prototype) ====
Original Gatearray of Amstrad is a sequencer (counter plugged with a clock), it manage manages synchronization between video card and z80 and memory access.
Historically there is a link between CU of CU/ALU, and... control bus and... how making your own sequencer. But I will say no more in order to not disturb these text part xD
