AI - applied inginuity drive IIgs help!

[thomas@pathlink.com (thomas)]

the power supply on my rom 03 is finally going silent (i.e. most of
the times it does not turn on - and when it DOES NOT turn on, when I
unplug the cord I hear few clicks from the psupply - anyhow - went
into my 'toy box' for another power supply and found this thing called
AI APPLIED INGINUITY disk drive that looks like a power supply with an
attached drive card (sort of a vulcan drive I suppose).

couldn't find alot of info on it so here go the questions - lots of
them! (if these have been answered somewhere, then please point me to
that direction!).

Q: how can I tell how large the drive is? looking at the labels,
nothing seems obvious - later I'll explain 'why' I'm a bit worried
about plugging it in...

Q: is this scsi or IDE? the connections look IDE and the card looks a
bit 'simple' for it to be scsi - i.e. no id jumpers, very few chips -
4 I think - etc.

Q: is the power supply a good replacement for the stock 03 psupply or
will I be 'loosing' something to gain the internal drive?

Q: will I need any drivers/etc. to get GSOS/prodos to play with this
puppy and what's the appropriate slot for this (the slot is 'short'
enough to NOT touch my memory card if placed in slot 7) and I assume I
can still use appletalk by setting that slot to appletalk in
conjuction with the drive (I'd be using this with a voc, zipgsx, some
audio extension on top of (not in it just on top of it) slot 1 that I
have not figured out yet, and a memory card I can't remember the name
right now - it's red, and only long enough to fit 4 1 meg simms)!!!!

Q: can I open the supply and swap out the drive (the labels warn me
left and right NOT to open it - what should I watch out for) - and if
I DO make it alive past opening the case, what's an appropriate drive
replacement?

the supply currently has a few 'white' spots on the case - not sure if
this is a 'warning' to not plug it into my one and ONLY 03 motherboard
or not.

lastly - if I can't use this psupply - would a psupply from an 01
mboard suffice in an 03 motherboard? I have a much better chance at
finding an 01 board and using it's power supply than to hunt around
town looking for another 03 board - well at least the gas prices are
cheap in the bay area - NOT!!!!!

thanks a bunch,
