    general purpose I/O board
  • it is a host for two industry standard Intel iSBX (IEEE-959) I/O daughterboards
  • supports both the 8 and 16 bit iSBX modules
  • ASDG offered two modules: a GPIB (IEEE-488) module and a dual serial port module
  • any other iSBX module can be installed: A/D and D/A converters, digital I/O, servo controllers, stepper motor controllers, etc.
  • Twin-X cannot DMA on the Zorro bus but it can be set up in a way that DMA requests from the mounted iSBX modules (which of course support DMA) triggers an interrupt in the Amiga
  • the iSBX modules appear to be standard auto-configuring boards for the Amiga
  • autoconfig status LEDs - when a module is correctly configured its LED lights up
  • two activity LEDs - when a module is accessed its LED lights up
