Re: Private Messages stuck in Outbox

As long as the receiver doesn't read it (or connect here - not sure which is correct), the message won't move to Sent items.

Re: MZ-700 tape not loading software

Putting 5V at READ signal shouldn't be so harmful - the chip will read a high signal, not much.

Re: MZ-SD2CMT - correct wiring?

Marcus Lausch told me he was able to load several Basic programs using .WAV and .MZF files. But you must do it in normal mode. Binary program can be loaded in ultrafast mode (~20s for 48KB loading - I modified the firmware so you can see in which mode you are on the screen now). Note that I added IR...

Re: [MZ-SD2CMT] GitHub link

I noticed I needed to plug USB because LCD16x2 was getting too more power and prevented SD card from working properly without the USB powering. For this reason, I decided to try the I²C 128x64 OLED since the input was solved by using an IR remote. After removing LCD16x2, now the MZ-700 can power the...

Re: MZ-SD2CMT - correct wiring?

Pin 3 was in used when there were some play algorithms still using a simple bit toggling. When all algorithms started to use OSP, ...

But I got a better result with TO8 keys as I could refine the experiment.
