Also exist a minimum AY clone chip from Yamaha named YMZ284-D with only 16 pins, because the I/O ports have been stripped out from the architecture.

There are on Ebay for about 9$ P.&P. included per unit.  From China of course, but new.

The CPC series of computers acccess the AY with an intermediate 8255 PPI chip, but the MSX do it directly  by Z80 port like the Spectrum.

In the production are 10 pieces of PCB for ZX Spectrum Emulator and 10 pieces of PCB for BusBridge.
More I do not plan.

After many hours of printing ...
Housing fits both for the original Busbridge, and to my clone.

It would be great if mixed with the Gosh Wonderful ZX Spectrum ROM, at least the keyboard parsing.
