Fujinet C64 hardware interface?


Recommended Posts

 

 

Greetings,

 

First of all, Happy New Year to all readers!

 

Second, congratulations for this great device!

 

 

Third,

 

Recently I saw a video of a Fujinet operating in a Commodore 64 system;

but currently there is no hardware information regarding the components and ESP32 I/O used for C64 interface

 

Will be this information available soon?

 

 

Thanks in advance,

Can you share a link to the video? I suspect you saw the Meatloaf project from @idolpx who is working to port Meatloaf functionality into FujiNet.

 

Yes, I think so

 

 

 

 

 

 

 

 

 

Surpringsingly, from schematics, is the IEC interface a direct one?

There are no transceivers or another level converters...

Correct, the connection is direct in the basic example there.

 

@idolpx has a FujiNet 1.6 with breakout board and has been testing with that on c64. 1.6 hardware has 74ls07 b/w the esp32 and the bus so that will probably be used for the c64 hardware also. You can find the current pinout for fujinet c64 and code in the github repo

Thank you so much, a very useful information;

its a clever idea reuse existing hardware driver ics
