I have seen several references that supposedly the 55/65xx Gazelle boards have an onboard 3.3v regulator which allows them to be installed into an older chassis (Quadra 630, Performa 588, 52/62/53/63xx and similar machines) without supplying 3.3v from the power supply like the Alchemy boards (from 54/64xx machines) require. However, upon trying this, I have had no luck: the boards either refuse to boot, or something doesn't work properly; for me they'll only work in machines where they're supplied 3.3v from the power supply.
I have tried a couple different Gazelle boards in a few different non-3.3v chassis and had the same results: no boot, or weird problems with disk access or something that disappears when these boards are used in a proper 3.3v chassis or the original boards are reinstalled.
Does anyone have experience of installing a Gazelle board into an older (pre-54/64xx/6360) chassis without modification? Or is this just a misconception?
