Re: MZ2TAPE: Fast transfer 100ko / min through the tape socket / MZ2TAPE : Transfert rapide 100ko/min par la prise casse

Bon je vois que tu as fait à peu près tout ce que je voulais faire (inclure le code dans le commentaire du header, etc.) - à un détail près - n'avoir que 2 signaux au lieu de 3.

Arduino side, you must connect P-12 with : 1 - N.C 2 - N.C 3 - N.C 4 - MOTOR (Arduino input, the same value as MZ input PC4) 5 - SENSE (Arduino output, MZ has no direct access through a PCx - but toggling it reverts the MZ input PC4 under the condition of not using PC3 as output to toggle the value ...

It won't work. MOTOR signal can only be input for Arduino. This signal is to trigger on/off the motor mechanism on MZ-1T01 - on Arduino, it is used to determine if the transmission should be resumed (motor-on) or paused (motor-off).

Re: [SD2MZCMT] GitHub link

But the original mzf2wav has a weird way to build its WAV file by issuing first a low value, then a high value instead of the expected high one followed by a low one. Example: If you want to issue "SP LP LP SP SP" with mzf2wav, you'll get: | 0 | 1 | 1 | 0 | 0 | _3__ _5____ _5____ _3__ _3__ _2_/ \_3_...

Re: [SD2MZCMT] GitHub link

For a 44.1 KHz frequency: - In legacy mode, a short pulse (0) is taken 22 cycles (11 high + 11 low) and a long pulse (1) is taken 42 cycles (21 high + 21 low). - in turbo mode x4, a short pulse (0) is taken 5 cycles (2 high + 3 low) and a long pulse (1) is taken 8 cycles (5 high + 3 low). 1) if your...

Re: LISTING ROM SFD-700 VERSION 2

It may take a little time to translate. Hope you aren't in rush.

EDIT: huh? I was answering to sharpmz post but I cannot see it anylonger.

Re: [SD2MZCMT] GitHub link

In fact, I saw you only need to read 100 short pulses for a GAP preceding a TAPEMARK. Same as the MZ monitor does: A GAP contains up to 22,000 short pulses but the monitor reads and counts only the first 100 pulses ( see the subroutine GAPCK at location $0FE2 ). The remainig pulses are not counted ...
