A Speech Synthesizer from [[Amstrad]] based on the [[SPO256]] -AL2 Speech Synthesizer

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 Status 1 (0=busySpeech Busy, 1=readyReady/data requestHalted) (SBY Pin, Standby) bit6 status Status 2 (used by 3D Stunt Rider0=Ready to Receive Data, Roland in Space1=Busy) (/LRQ Pin, Glen HoddleLoad Request) bit5-0 unknown/unused Not used (the above status bits are garbage, probably the /LRQ and SBY pins) (unknown which is which one though?usually high)

Port FBEEh WRITE- SP0256-AL2 Allophone: bit7-6 unknown/unused (should be zero) bit5-0 allophone Allophone number

Port FAEEh WRITE - Accidently used in the included RSX driver cassette (the driver sets BC== Supported Games ==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: * [[SP0256]]* [[SP0256 Voice Generator]]* [[SP0256 Instruction Set]]* [[SP0256 Allophones]]* [[SP0256 Pin-Outs]] == Software Support ===== Games ===* [[3D Boxing]]* [[3D Stunt Rider]]* [[Alex Higgin's World Snooker / Higgins World Pool]]* [[Alex Higgins World Snooker]]* [[Darkwurlde]]* [[Glen Hoddle Soccer]]* [[Roland In in Space]]* [[Tubaruba]] === Serious Software ===* [[FutureOS]] (limited) '''Caution''' - Some webpages do (incorrectly) list further games: Gremlins (spanish version),Seablood and Robin of Sherwood (these contain code for using Port FBEC & FBEF for some kind of data transfer, possibly for [[PDS development system]] - but, not for speech).Also, Dragon Gold is listed as speech game (not sure why, it doesn't seem to use any special I/O ports; unless different versions of that game exist?)
