Changes

The clock frequency (passed to In the SSA-1, the SP0256-AL2 speech chip) is fixed, clocked by a 3.12MHz ceramic resonator (unlike the exact frequency similar dk'tronics device, where it is unknown (?clocked at 4MHz).

Uses The SSA-1 uses I/O port: [[I/O_Port_Summary|#FBEE]], of which (according to the manual) only A10,A4,A0 are decoded.

Port FBEEh READ- SP0256-AL2 Status: bit7 Status 1 (0=Speech Busy, 1=Ready/Halted) (SBY Pin, Speech BusyStandby)

bit5-0 Not used (garbage, probably usually highzhigh) Port FBEEh WRITE- SP0256-AL2 Allophone: bit7-6 Reserved (must be zero) bit5-0 Allophone number ;data  Port FAEEh WRITE - Accidently used in the included RSX driver cassette (the driver sets BC=FBEEh and executes OUTI, which pre-decrements B, so the OUT accidently goes to FAEEh - the driver works despite of that bug since FBEEh is mirrored to that address). * A new allophone number can be send when Status.Bit6=0.* The allophone number should/must be in range of 00h..3Fh (6bit).* However, the whole 8bit databus is connected in the SSA-1. For details on the speech chip, see:
