Re: Conflicts with floppy? Where do I start?

Ok, so I've removed all cards except the disk ][ IO Card and the AE 80
column ram card in the aux slot. I've verified that the disk ][ ribbon
is not offset, and has the red stripe toward pin 1 (and away from pin
19). I've tried slots 4, 5, 6, and 7. I've used a handful of disks
that came with the A2 when I bought it, and each said Startup (some
for Appleworks, some from ProDos). Same result: Turn power on, card
chunks, then whirs, but screen never progresses past "Apple //e". I
can hit ctrl+reset and get into apple rom and even bootstrap ADTPro,
but that's as far as she gets. I've grounded myself out and tried
gently pressing on all of the chips to ensure they're seated properly.
I've done most things, shy of actually removing each chip from the
socket and re-seating them.

Any other ideas?
