Using ASCI2STM in conjunction with a real SH204

[galumph]

Spent this morning trying to build a ASCI2STM on a breadboard. Haven't finished yet but I was wondering if it would be possible to daisy chain an original SH204 drive to the ASCI2STM board? To complicate things further I did modify my SH204 by adding a 2nd HD (34MB 5.25" full height drive). Would I need to add the SD cards as socket 3 & 4 as the SH204 would be 1 (c:) and 2 (d:) or am I being overly optimistic?
