Hi,
To get my SX32 to work more reliable, I had to do something in addition to the mods on my website, I wired directly from the CD32s power input to the underside power pins of the IDE interface, this cured all my intermittent boot problems. A poor picture of the mod is
hereI used 28 AWG? (7/0.2) wire for this mod.
I also regularly clean the edge connectors with Isopropyl alcohol.
The SX32 pro is not the most reliable bit of kit I have owned but it is neat :-)
