'''Alignment of HSYNC Interrupt''' : a button of starter kit display HSYNC loopback lines, it's usefull to compare to a Maxam test that alternate color on them
'''Sniffing of a real Amstrad''', I listen to some wires of my Amstrad CPC 6128 plus, but I can't access VSYNC/HSYNC output of CRTC, so I have to buy another model in order to do this test. In fact you can listen at clock of Amstrad and transmit it to FPGA DCM component, resulting a accelerated clock sequence, that's it, with FPGA DCM you can overclock output Amstrad clock signal in order to insert more operations, I use this tips tip for listening signals and save them inside starter kit asynchronous RAM (write, stop write, write, stop write... i'm a perfectionist paranoid...)
