The P8X180 Computer System
Presenting the P8X180 Computer System.
This is a Single Board Computer (SBC) based on the Zilog Z8S180 8-bit microprocessor, with the help of two Propeller 1 microcontrollers driving the onboard peripheral interfaces.
The main board includes the device interfaces needed to run stand-alone such as VGA video, USB or PS/2 keyboard, mass storage, and others. Four slots allows to expand the system with additional peripherals such as modems, printers and hard drive controllers.

- 512 KB flash ROM
- 512 KB static RAM
- 256 colors VGA video
- USB and PS/2 keyboard
- Dual channel audio
- SD Card Storage
- 1 Full TTL serial port
- 1 Simple TTL serial port
- I2C and SPI interfaces
- Battery-backed Real Time Clock (RTC)
