Processor: EC030@40Mhz, or 030@50Mhz
FPU: Optional (both PGA and PLCC sockets)
Max Ram: 64MB
Ram Type: 2x72Pin SIMM slots.
Fast SCSI-II: Optional
The memory on this board is configured via jumpers.
Aswell as a connector for the SCSI-2 there is anothe expansion connector on this board. The purpose of this connector was for future expansions but I do not know of any that exist.
Also contains a MAPROM jumper for copying the kickstart into fast ram to speed up machine performance.

MAPROM If memory is installed on the Blizzard 1230-II you can load Kickstart into the faster RAM to speed up the execution of operating system functions. If the MAPROM jumper is removed, Kickstart will be automatically copied over to the RAM. If the jumper is installed Kickstart will be executed on the ROM.
In position 2-3 the co-processor is operated synchronously, with the central processor clock. If you want to use a co-processor with another clock rate this jumper must be set to position 1-2. For asynchronous operation a second oscillator must be installed.
