Your present card will work fine with adapter cables (20 pin to DB-19)
available from Aplied Engineering, among others.  They might dangle a
little, but you could detach your drives without opening your machine.  One 
advantage to this is that you need not daisy chain.

Almost certainly DB-19 and could be second, but not first, drive in daisy
chain.

DB-19 and can be either first or second in daisychain.

DB-19 and can be either first or second in daisychain.

_Also, the LASER drives:

DB-19 and could be second, but not first, drive in daisy chain.

_  5.25 LASER Daisy chain  ;Please explain
DB-19 and can be either first or second in daisychain.

Note that "IIc" style drives can be second in a daisy chain or be in a
"daisy-chain of one" by themselves.  "IIgs" style drives can be first or
second in a daisy chain. (On the GS, the 5.25 drives go further out on the
daisy chain than any 3.5 drives.)

I reccomend you get two IIc style drives and use them with your existing
card with adapter cables.



A question: can you hook two external 5.25 drives to a IIc+ ?
