An accelerator which plugs into the trapdoor slot of the A1200. An optional Fast SCSI-II controller is also available.
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.
