Technical Specs.

The clock frequency (passed to the speech chip) is fixed, the exact frequency is unknown (?)

Uses I/O port: #FBEE, of which (according to the manual) only A10,A4,A0 are decoded.

Port FBEEh READ: 

 bit7   Status 1 (0=Speech Busy, 1=Ready/Halted)   (SBY Pin, Speech Busy)
 bit6   Status 2 (0=Ready to Receive Data, 1=Busy) (/LRQ Pin, Load Request)
 bit5-0 Not used (garbage, probably usually highz)

Port FBEEh WRITE:

 bit5-0 Allophone number               ;data can be send when Status.Bit6=0
