Serial port?

Is a serial port on the road map? A standard DB9 serial port would instantly add MIDI output capability. Controlling an old school Roland Sound Canvas with a crazy powerful 8 bit machine sounds like instant awesomeness to me :D

Hello,

Yes, we are intending to implement the C65’s serial port that shares pins on the User port, but is a real UART. From memory, it explicitly supports MIDI baud rates.

So that means homemade User port cable to serial/MIDI, that fine by me :)

Maybe I misunderstood you, that means a real serial port sharing pins with the user port??

Yes, that is our current expectation, that we will implement the C65 UART, the same way the C65 did: When you set the registers to turn the UART on, it takes control of several pins that are normally controlled by the CIAs on the user port.

Nice, are the level TTL or standard serial? Or will it need something like a MAX232 to connect to standard serial peripheral?

I believe the C65 specifies it to be 5V TTL.

So it won't be as easy as I thought it would haha. No big deal.

There is no need to “register”, just enter the same name + password of your choice every time.
