09.007 Will a Duodisk function correctly on my ROM 3 GS?
I have three Duodisks. The one connected to my flagship ROM 3 IIgs has
had the resistor and capacitors clipped out as recommended in a memo from Mitch
Spector. It works perfectly!

A Duodisk may not be entirely functional connected to the usual ROM 3
"Disk" connector (i.e. the SmartPort). Users report that the system may not
start up unless a write-protected disk is inserted in the Duodisk. Apple, in
Tech Library notes #5010 and #5434, mentions these reports and says that there
is some code in the ROM 3 ROM that does not handle the interface to a Duodisk
properly. Apple's workaround is to connect the Duodisk to a drive interface
card instead of to the Smartport.
