Motherboard

Micro ATX
Model: D1000

The Dyno Computer Motherboard is the foundation of the project. It provides all of the functionality of a complete computer and allows for expansion via its Dyno•Bus slots. The motherboard features:

  • A Zilog Z180 CPU running at 18.432 MHz,
  • Two asynchronous serial ports accessible via TTL-levels or RS-232,
  • ROMWBW-compatible memory with 512 MB of ROM (Flash) and 512 MB of battery-backed up RAM managed by the Z180 MMU,
  • Real-Time Clock with support for CPU reset at power-up and watchdog monitoring,
  • Support for 8- and 16-bit IDE storage devices (i.e., Compact Flash, Hard Drive and Disk On Rom),
  • Uses ATX power supply with soft controls,
  • A system register that controls SPI addressing, a beeper and software-control to reset or shutdown the computer, and
  • Six Dyno•Bus expansion slots.

The Dyno•Bus provides access to:

  • The 8-bit data bus;
  • The 20-bit address bus;
  • The Z180 control signals: (RD, WR, MREQ, IORQ, M1, WAIT and RESET;
  • The Z180 bus mastering signals: BUSRQ and BUSAK;
  • The Z180 DMA signals: DREQ1 and TEND1;
  • The Z180 clock signals: PHI and CLK;
  • The Z180 interrupt signals: INT0, INT1, INT2 and NMI as well as the interrupt cascading signals IEI and IEO;
  • The Z180 CSIO signals: CKS, RXS and TXS as well as the slot selection signal: SEL for SPI emulation; and
  • I²C signals: SDA and SCL.
