ALS "The CP/M Card" trouble

- Summary: I can't get it to start.
In my quest to learn about as many different Apple-hosted CP/M
systems as I can, I recently purchased an Advanced Logic Systems
(ALS) "The CP/M Card" from a fellow via 'comp.sys.apple2.marketplace'.
The seller says that he tested it in his Apple IIgs the day he
shipped it to me and it worked just fine.
I have been unable to get the card to start up in any of my Apple ][
machines (A 64K Apple ][+, a Franklin ACE 1000, or my enhanced
Apple //e).
Usually the card starts to run but then just puts some garbage on
the screen until it hangs someplace. Sometimes it gets as far as
activating my 80-column card (with or without garbage). Sometimes,
the software can't even find the card at all.
Specifically the card says:

The CP/M CARD ^tm REV B [along bottom edge under DRAM]
(c) 1983 ALS 005138 [on circuit side, 005138 in felt-tip]
Although Apple-CP/M'ers seem to be few and far between (especially
here), I'd appreciate any feedback from anyone who's ever used an
ALS "The CP/M Card" to help me locate the trouble and solve it, if
possible. I'm also missing disk #4 of the distribution set. I
would appreciate a copy of your disk #4 in any event.
For those who are unfamiliar with the ALS "The CP/M Card". It is
a coprocessor card co-developed with DRI which runs CP/M Plus
(v3.01b) on Apple ][-series machines. It carries 64K on the card
for transient programs (and minimal OS) use while the OS resides
mostly in the Apple's main memory and the Z80 is free to execute
code from either bank, just as if it were a native two-bank CP/M
Plus machine. Either the Apple's 6502 CPU or the Z80 may do I/O
through the Apple's I/O ports and the Z80 may load 6502 subroutines
and pass control to the 6502 for execution.
Thanks for listening.
