ZX-Uno

Is it possible to add in the SETUP the option of connecting the generator SAA1099?

Software for SAA1099 for the ZX Spectrum: http://micklab.ru/ZXMSoundCard.htm . Basically the software uses 128k, some programs uses 256k for D7 #7FFD.
Used decoding: CS_SAA#FF/ = A0/ + A1/ + A2/ + A3/ + A4/ + A5/ + A6/ + A7/ + A14/ + A15/ + IORQGE + WR/ + TRAP
CS_TIMEX#FF/ = A0/ + A1/ + A2/ + A3/ + A4/ + A5/ + A6/ + A7/ + IORQGE + WR/ + TRAP/
To differentiate Timex and SAA uses the trap command code IN/OUT nn, A .

The SAA is a little big, but I will try to fit in the core.
