This is what happens. I turn it on and the standard
"Welcome to Apple IIGS" screen comes up. The progress
thermometer moves to the end, but the hard drive
isn't accessed since the screen comes up. Then
nothing. The odd time that it manages to actually
load something it seems to forget the name of the
drive I'm booting from. Booting from a floppy gets me
a little further but not for long.

I haven't even plugged in any more cards than,
RamFAST Rev. D, TransWarpGS, DP RamPlus 4MB card.
That's it. Bare bones. I've run more than that in the
past. And this is using a ROM 3 mother board as well.

Also I'm using the power supply from a Vulcan Gold.
Though the original power cable that came with it was
a little skimpy, and yes it had a burnt mark on the
+5V end of the connector, but I got a heavier one
from my older Vulcan drive and still the same result.

I was already considering this but am having problems
finding proper sized pins for the connectors. With
the Vulcan PS there is an extra set of leads for the
hard drive. And before you ask, I'm not using it
anyways, but want to keep it as an option. For a
number of years I've been running the HD off of a
separate PS from a Mac LC.
