Sharp MZ

Sorry, I mean it's pretty easy to find Amigaists to buy over €500 accelerators (those I cited above) for their favorite computers.

And I should have probably said: "Sharpists are not Amigaists" in this order.

Mode 2 (one cycle pulse every N cycles): - CNT0 = 1 -> 1.1MHz/1 -> 1.1MHz -> avg(V) = 5V on sound pin. - CNT0 = 2 -> 1.1MHz/2 -> 554KHz -> avg(V) = 2.5V on sound pin. - CNT0 = 3 -> 1.1MHz/3 -> 369KHz -> avg(V) = 1,75V on sound pin. - CNT0 = 4 -> 1.1MHz/4 -> 277KHz -> avg(V) = 1,25V on sound pin. ......

Anyway, I already indicated it cannot really be done. Moreover, there is a thing we call "priming" in psychology: when you type your sentence and let it speak, you believe hearing it. Just make a program which just speaks without displaying the sentence, you won't be able to understand. Au...

I'm experimenting those in-game with my current Space Rally game. But yeah, I'm NOT making any text speech as you need a better resolution than the ones I used.

Yep, Amigaists are not Sharpists. You know stuff like 68060 (warpX60) or 69080 (Vampire)...

it's pretty easy to make PWM with 8253, using mode 0 without programming its counter to output 1 permanently and mode 4 to output 0 permanently. You can even put a variable voltage like 5V/n where n is the counter of mode 2 (instead of mode 3) to attenuate volume programmatically.

This is what I get with my SpaceRally.wav: LONG:1;tick0=10.7;tick=7 LONG:1;tick0=10.1;tick=7 LONG:1;tick0=10.1;tick=7 LONG:1;tick0=10.9;tick=6 LONG:1;tick0=10.4;tick=7 LONG:1;tick0=10.2;tick=6 LONG:1;tick0=10.5;tick=6 LONG:1;tick0=10.3;tick=6 LONG:1;tick0=10.1;tick=6 LONG:1;tick0=10.7;tick=7 LONG:1;...

Le morceau que tu as choisi n'est ni un bloc de donnée régulier ni une entête d'un fichier pour MZ-80 K. De plus il est extrêmement court.

To have an idea how the header starts (it always sounds similar for any MZ-80 K program in a wav file):
I cut the big part of the data so it won't be loadable but at least you hear the wav file.

je n'entend pas le header caractéristique (un espèce de "bouingue") et ça me semble un peu répétitif comme motif.
