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 blog:
https://olimex.wordpress.com/2023/04/21 … r-project/

Here is how AgonLight2(z80) looks like:
https://www.olimex.com/Products/Retro-Computers/BOX-AGONLIGHT2-BLACK/images/BOX-AGONLIGHT2-4.jpg

Website:
https://www.olimex.com/

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.

Je to samostatný počítač 6502 alebo sa dá nejako pripojiť k slotu 6502 v XL?

It is standalone. Like RaspberryPI but will have bus (uext) so will be possible to connect it to Atari for example. Or smart home etc. My idea is to use it as cheap turbocard(16mhz 6502, 256kb ram, 2mb flash for firmware/os, or graphics card 640 x 480 x lot of colors(depends on video ram)).
So like 30euro + 10euro cartridge adapter or so.
Graphics card can be good for text/coding apps or maps inside game or hires pixelart. There can be game using Atari 160x200x4 or more colors and on 640 x 480 will be for example map and items (mmo or adventure or zelda like game or dune2 like game). Or so.
It can be interesting. It will stay 8bit 6502. It will stay as upgrade.

But is standalone computer. So maybe Atari remakes on it too can be possible. He sold 1000 Z80 AgonLight2. So lot of peolple.

There's Agon 65X in the works already:

Not exactly 6502 but close enough...

So Olimex has made first prototype.

The board size is only 80×55 mm but do not be fooled this is complete 6502 computer with:
- wdc w65c02 14mhz!!! cpu
- HDMI output
- USB host for keyboard
- Audio output on 3.5mm jack
- Small speaker
- UEXT connector with +3.3V, GND, I2C, SPI, UART6502 BUS 40 pin connector with all 6502 signals on it!
- RP2040 with 2MB Flash to handle all software defined peripherals and RAM

If You are 6502 or RP2040 coder You can help with development and get board sooner.

I can imagine play some Atari game conversions on it. Or plug it into cartridge port and use it as turbocard / gpu...

Why RP2040 is powerfull:
133 MHz dual ARM Cortex-M0+ cores (can be overclocked to over 400 MHz[9])Each core has an integer divider peripheral, and two interpolators.264 KB SRAM

So it can emulate some Atari chips like Pokey.
And with 8mhz (to 14mhz) 6502 cpu, 320x240x 256colors will be fun.
Price will be good like 50euro.
And via some conversion board can be used as usb, second cpu, gfx, audio, flash eeprom board...

Od samoróbki 6502 to emulacji Atari daleka droga. Nie widzę deklaracji, aby autor sam to chciał wykonać.

It was done with... ESP32 (price 6$):

In few days there will be production version.

Some news:

Graphics test demo:
https://youtu.be/SXrgtiNUdP0?feature=shared

My idea is to have 30euro turbocard + 10euro cpu adapter for XE/XL also plus rp2040
for FPU(emulated something as 68882 or amd, weitek) for example or as 320x200x16 from 512, 640x200x4, 640x400x2 graphics card for example or bios firmware...
Somthing similar idea to PiStorm on Amiga but real cpu.
