I tried that too Wayne.  Also tried...lets see:
Hooking it to a stack of second vendor floppy cards from SCI, Franklin, and
others..
Hooking it to a Laser  128, IIc, and IIc+,
Hooking it to a Liron card
Hooking it to a Superdrive card
Hooking it to as you said, a disk card out of a 3.5 drive, also tried the
Unidisk's card, also tried daisy-chaining it to another unidisk or 3.5 or a
AE 3.5 clone
Hooking it through a PCTransporter

None of the above worked.

I took a HD20 apart and looked at the chipsets and if you look back on the
other thread you can find both my description of the chips and several of
the more techie member's response.
As I recall, the concensus was that this looked a lot like the setup on the
liron card in terms of the chipset, but, that the firmware of the HD20's ROM
was such that it woudl not allow a Apple II to access it.  now MY theory
here was that if one could snarf the ROM from say..the Laser 128 or some
other A2 like   board and re-flash/burn the HD20 with that info you could
get it recognized.  But hey, I have not a clue what I am talkin about ;)
