The DayStar Turbo 040 is a MC68040 accelerator for 68k Macintoshes. The socket is designed for a IIci Cache slot and a number of adapters were created to adapt the IIci slot to work with other Macintosh models. The adapters covered here are for the IIsi and SE/30 PDS slots, which are mostly compatible with each other, except for cases where the clock speed of the host machine matters.
WARNING: DO NOT CONNECT DAYSTAR 120 PIN ACCELERATOR BOARDS WITHOUT THE PROPER ADAPTER BOARD. IIci machines generally do not need an adapter board if you see IIci written somewhere on the board.
