  • 64 DIP sockets accept up to 8 MB RAM
  • accepts DIPs in groups of 16 giving 2, 4, 6 or 8 MB RAM
  • AutoConfig does not support 6 MB configurations, so it is represented as two cards (2 + 4 MB)
  • uses 1M×1 (411000) DIPs
  • no waitstates
  • memory autoconfig
  • recoverable RAM disk (rrd.device)
  • the Zorro I version (8M) fits into any Zorro I expansion chassis, such as ASDG's Mini-Rack
  • the Zorro II version (8MI) was licensed to Progressive Peripherals

    • reliably transfers data at speeds up to 76800 bps on one port or 38400 bps on two ports at once
    • can communicate at 31250 and 76800 bps but not at 57600 bps
  • 8 MHz version:
    • reliably transfers data at speeds up to 115200 bps on one port or 57600 bps on two ports at once
  • uses siosbx.device
  • supported by Linux

    Ethernet interface
  • DP8390 controller IC
  • LAN Rover:
    • 10Base2 (BNC) and 10Base5 (AUI) connectors
    • two 8 kB SRAM buffers
  • EB920:
    • 10Base2 (BNC) connector only
    • two 32 kB SRAM buffers but uses only 16 kB of each
  • buffers are accessed with DMA
  • adjustable interrupt settings
  • network address ROM - some boards shipped without it and needed manual hardware address configuration
  • SANA II compatible
  • supported by NetBSD and OpenBSD
  • 10-20% slower than the Commodore A2065
    Jumper Settings (LAN Rover only)

    GPIB (IEEE-488) interface
  • a cheaper successor of ASDG's Twin-X iSBX GPIB daughterboard combo
  • 16 kB static RAM
  • the board cannot DMA on the Zorro bus but there is an option for DMA to/from the GPIB controller and the onboard static RAM

side expansion port
    Zorro I expansion chassis
  • two Zorro I slots
  • connects to the A1000 side expansion port
  • 85 watt internal power supply
    Mini-Rack C
  • does not implement all Zorro signals, most importantly it lacks +12V and -5V
  • unbuffered slots
  • works well with RAM cards (such as ASDG's own 2M and 8M), but not with HD controllers
  • one exception for HD controllers is the Expansion Technologies Escort ST-506 controller card, which does not need the missing signals
    Mini-Rack D
  • implements all Zorro signals
  • buffered slots

    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
