processor
- 68040 @ 28 / 33 / 40 MHz or 68060 @ 50 / 66 MHz
memory
- A4000: four 72 pin SIMM sockets accept up to 128 MB RAM
- A3000: two 72 pin SIMM sockets accept up to 64 MB RAM
- supports 4, 8, 16, 32 MB SIMMs, 60 ns
- accepts FastPage and EDO RAM
- supports the very expensive ED-RAM (not EDO)
- memory disable jumper
SCSI 2 controller
- not Fast SCSI 2
- allows autoboot and supports RDB
- 50 pin internal header
- optional external SCSI connector
- not compatible with Quantum and some IBM hard disks
notes
- the RAM ends up as separate memory chunks unless there are only 32 MB SIMMs on the card or only one SIMM of any size
- A4000: the card functions better if there's still a 4 MB SIMM on the motherboard
- A3000: a wire has to be connected between the A3000 SCSI chip and the Kickstart chips
