ASDG Twin-X

> Company: ASDG, US
Date: 1988
Amiga: 2000, 3000, 4000
Interface: Zorro 2
Autoconfig ID: 1023/255

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
