Bulgarian Olimex manufacturer of ARM singleboard computers similar to RaspberryPi also AgonLight2 Z80 hobby computer is developing 30Euro 6502 computer called NEO6502.
He want use RP2040 for graphics, sound and i/o key/mouse and disk.

Here is how AgonLight2(z80) looks like:

Some specs:
- real 6502 processor.
- 264kb RAM on RP2040.
- W65C02 from WDC can be overclocked up to 16Mhz also slow mode 1-2mhz
- DVI/HDMI so that you can connect it to your home TV or modern monitor.
- support for a modern USB keyboard
- PSG sound synthesizer like the popular C64 SID
- the power supply should be via a USB-C
- UEXT connector with modern interfaces like UART, I2C, SPI.
- disk storage for code.
- the 6502 bus should be available on a slot/connector(cartridge) so that additional hardware can be easily added on
- 2MB of external SPI flash to hold the firmware (firmware/OS/BASIC)
Maybe we can suggest/modding RP2040 firmware:
- use pokey instead of SID (or external UEXT card)
- use ANTIC/GTIA or VBXE type of emulation (or external UEXT)
- somehow port Altirra or ATARI OS/BASIC to boot from flash
- 2x ATARI joystick
To have 14mhz 30Euro hybrid ATARI/NEO6502
Or we can just port games from ATARI 800.
Or connect it to cartridge port use as turbocard/graphics card.
