  • 68EC030 @ 25 MHz, PGA
  • 68882 @ 25 MHz or up to 50 MHz with separate oscillator, PGA
  • eight 30 pin SIMM sockets accept 32 MB RAM
  • supports 1 or 4 MB SIMMs, 60 ns or faster
  • accepts SIMMs in groups of four giving 4, 8, 16, 32 MB RAM
  • two feature connectors intended for A2630 memory expansions
    • Access32 needs some rework, otherwise the SCSI controller does not work
    • for DKB 2632 compatibility the Extas (external address strobe) jumper has to be set to external
  • in 68000 fallback mode up to 8 MB of RAM remains in use - 4 MB (or all) can be disabled for BridgeBoard compability
  • burst RAM access can be disabled by jumper or software
    SCSI controller
  • the same electronics as the Trumpcard Professional
  • 53C80 controller IC
  • uses polled I/O, not DMA transfer
  • 50 pin internal header
  • 50 pin Centronics external connector
  • a 3.5" hard disk can be mounted on the card
  • autoboot ROM - autobooting requires at least Kickstart 1.3
  • when booting from floppy disk, the hard disk is not mounted automatically in order to prevent virus infection - but pressing the left mouse button during startup forces the HD to be mounted
  • pressing the right mouse button during startup brings up the Vector Boot Options Menu
  • SCSI share networking - Vector's SCSI ID can be set with jumpers
  • in 68000 fallback mode the SCSI controller still works
  • autoboot disable jumper and SCSI disable jumper
  • if run on an A500, the 7 MHz clock has to be fed to pin 9 on the board and the appropriate jumper has to be set
  • supported by NetBSD
