I've been able to run both Alex's card and a real Applicard in any slot without problems. Every once in the while it seems like the Alex-Card fails to reset properly, but an OA-Ctrl-Reset gets things going again.

Interesting. I never saw that happening on my 2e but I'm sure I didn't
turn it on as often as you did.
There is no "active" reset on my board - it relies on a reset coming from the Apple slot. IMHO a good assumption because the Disk ][ card
drives this live low for a few milliseconds. In addition the first thing
the PCPI boot software does is sending a reset command to z80. Of course
that is a "soft" reset.

I won't swear that there isn't a problem with the machine, however. Haven't had the energy to drag another one out of the garage yet.
