-===== X68000 Hard Disk =====
-==== External HD connector ====
-All X68000s (even the SASI-based models) seem to have standard pinouts for the external hard disk connector:
-*Original model, Ace, Expert, Pro: [[http://www.gamesx.com/hwb/co_ScsiExternalCentronics50.html|Centronics 50-pin]] with /ATN, PARITY and Termination Power unconnected.
-*Super, XVI: Standard [[http://www.gamesx.com/hwb/co_ScsiExternalCentronics50.html|Centronics 50-pin]].
-*Compact XVI, X68030, X68030 Compact: [[http://www.gamesx.com/hwb/co_ScsiExternalHiDSub.html|High-Density Centronics 50-pin]].
-==== Internal HD connector ====
-All X68000 machines have a custom internal hard disk connector.
-The pinout for the SASI-based machines is as follows:
-^Pin^Description^Pin^Description^
