Features

  • Includes VGA, PS/2 and USB-Serial converter
  • Enough Internal SRAM to make small (16KB) BASIC computers

Limitations on MultiComp compatibility

  • Very limited I/O
    • Most of the I/O pins are shared with the 16-bit Video
    • Would require removing R-packs to gain I/O
  • Driver for PL-2303HX USB-Serial doesn't work under Windows 10 (painful workaround)
  • No SD Card storage
  • No external SRAM but very large SDRAM (not supported yet in our builds)
  • Would require a mod for serial hardware handshake (there's a pin or two free on the I/O which could at least do RTS)

Additional Features

  • On/Off switch - nicer than plugging/unplugging DC power cable
  • 4 pushbuttons
  • Four digit 7 Segment Display
  • IR LED
