I am glad you managed to sort out issues with the other clone. :)

A small update, because finally I assembled my board and tested the modified audio in circuit. It works fine and the simulator can record (in BAW & TAP) singals generated by a genuine ZX Spectrum or...

The prototype of the AY replacement in SMD works fine and I've tested it up to 30MHz :) Great work Evgeniy.

Hi,

I've been trying to force the ZX Taper to record anything from a genuine ZX Spectrum 48K (Iss2) for a few weeks and finally I manage it with a huge support from zipp @ speccy.pl. Now the input...
