Hi guys,
I remembered the old days with RVPC. It's a nice toy...
I discovered a small bug during testing. RVMON 1.0 changes the idle state when beeping after the signal ends. So after every second beep, current continues to flow through the speaker. If you ever modify RVMOV again, it would be a good idea to fix it.
When I was thinking about RVPC, it occurred to me that if instead of CH32V003J4M6 ...A4M6 were used, an I2C bus could be brought out. The user could solder an I2C EEPROM to it. Then it would be possible to save the work done on a "cassette recorder" (or floppy disk?)  :)
Even if it were a 2 Euro computer, everyone would be happy to add 1 Euro for a floppy disk drive  :D
And implementing Tiny Basic would be perfection itself.
Good luck with your future work. Stan

Hi
CH32xxx is too low end, the new RVPC-II will be with RP2350 and will have HDMI with 80 col display, USBx4 hub for keyboard and joysticks, Audio codec, and 16MB Flash 8MB RAM.
Then there may be CP-M, BASIC, PASCAL, etc etc.
It will not be 1 EURO but still will be quite affordable ;)
