Hello friends.

 

Olimex ARM sbc also Z80 AgonLight2 manufacturer will produce 15usd/euro ESP32 board (they want use it for PC and cp/m emulation). But also can emulate ZX, NES, Vic20, Amstrad.

 

 

So what about port Rossum A800 ESP32 emulator https://github.com/rossumur/esp_8_bit on it. Instead of bluetooth keyboard ps/2 and connent real joystick.

Some specs:

ESP32-WROVER
4MB FLASH
8MB RAM
SD card
PS/2 key and mouse
UEXT a SPI SERIAL
LiPo connector
LCD port
Audio out
PCB 105 x 65 mm

How to connect real w65c256 cpu and use it as serial text graphics card similar to XEP80 and use ps/2 keyboard as input.

This is very interesting so in theory we can use it via some serial connection as external text / graphics based gpu card or ps/2 keyboard input.

So for 15usd we can have something similar to XEP80 or low cost graphics card!
