From the project
WDC 65C02 based computer with a large RAM bank
This computer is currently still deep in hardware development but has a diverse set of planned features like hardware based random numbers and way more RAM than what is reasonable along with an implimentation of the VERA by the 8BitGuy.
This is by far not a finished project as these features awaiting implimentation:
1. Memory bank 2. Proper random number generator 3. Micro SD card 4. Better display or VGA output 5. Easily reproducable PCB's
