Re: MIST C64 core

... but is it mechanically separates the motor, too? I don't see any switches. I don't have a Datasette at home, but if you say so, I believe. Yes, when no button are pressed on tape deck the tape doesn't move even if motor is actually rotating. It can be observed when the play button is released w...

Re: MIST C64 core

But I've checked the 1530 schematics, and the buttons are not connected to the motor at all: it's always started by the CPU. So it can decide to start the tape even if the tap_play is not active. For sure you are right but it is more sure that the tape is not advancing and that there is no (useful)...

Re: MIST C64 core

I think it should be useful to add directly tap_play to the equation of c1530 play input. real c1530 act this way, motor can be set to ON but cassette doesn't advance if play button is not depressed. It is obsious to be said, but it has been more obvious to me during my last test with real c1530 to...

Re: MIST C64 core

Yeah, it would be nice (EAR IN without more additional components, but I'm not sure if it would work or not...) You can ignore the motor control, and start/stop playback manually, but the button sense must be connected (controlling from OSD like with TAP files is enough, but handling both manually ...

Re: MIST C64 core

Sorry I didn't get that you were speaking about using a real c1530. As said by someone it will required a few external circuit to adapt sense and motor signals...

No need for ear input because wav mode is already done, read speed may be adjusted if necessary.

Re: MIST C64 core

Also added safety checks to not read if the FIFO is empty (maybe it's not needed, the DCFIFO can protect itself) I understand you want to prevent reading empty fifo. But in any case reaching an empty fifo before end of tape will end at 99% to a load failure because the next timer timeout won't wait...

Re: MIST C64 core

At the end I was successful. I've restructured the code a bit, I wonder why didn't you use the fifo reset signals? Also added safety checks to not read if the FIFO is empty (maybe it's not needed, the DCFIFO can protect itself). And finally, it was more convenient to use a 8-bit interface on MiST. ...

Re: MIST C64 core

@slingshot, thanks for your interest in that work. I first start with tap mode and divider by 32. It works with simple tap (I use a 1 single line basic program saved from vice). Then I try some game tap which works ok until I try crazy comets. This game uses very short pulses. I didn't succeed with ...

Re: MIST C64 core

Just release a c1530 wav/tap loader for FPGA64 on DE10-lite board with zpuflex control module. It should be possible to adapt to MiST/MiSTer. It requires a simple 32bits width I/F to push data into fifo. Wiring to FPGA64 is quite strait forward. Good cia6526 requested on irq clear management (don't ...
