Based on modular design.
This is a Grundy Newbrain Hardware Emulation.
- The CPU is running at 10Mhz,
- The system has a total of 96Kb RAM newbrain uses 32KB as Ram and another 32KB as ROM (Non writable RAM to be exact).
- The Tang Nano 9k FPGA implements the logic of the system and the MMU.
- The Tang Nano is wired to the dual port 64Kb RAM and implements the VGA signal and character generation.
- CH376S module is used as a storage device with parallel interface.
- LCD 16×2 using i2c and
- PS/2 interface (Keyboard) (ps/2 or usb socket).
