Darn, there was a mistake... so I had to redo it...
- - - - -
Let me answer like this...
In a BA123:
o The Qbus passes direct from slot1/ab to slot4/ab
o For slots 5-12, it does the serpentine (5/ab, 5/cd,
6/cd, 6/ab, 7/ab, 7/cd, etc...)
o All dual boards must be placed at some point in the
serpentine. For slots 1-4, this means AB. For
slots 5-12, this can be either AB or CD.
o Quad boards which may not go in CD must go in slots
5-12
o For quad boards which can be either CD or Q/CD, the
jumpers on-board must be set for the slot you are
placing it in (there should be a couple of jumpers
which are removed if the board is placed in a Q/CD
slot, 1-4, and installed if it is placed in a Q/Q
slot, 5-12)
o For quad boards which can only go in Q/Q, they may
only be placed in slots 5-12.
o If you follow the serpentine, there should be no
empty Qbus slots between the processor and the last
board in the bus (there are exceptions, but for now
regard it as a hard and fast rule).
o For any gaps in the serpentine, you should install
a M9047
o The RQDX1 is a mutant, since it doesn't pass any
grant signals, it must be the last board in the bus
o The RQDX2 tried to correct this, but didn't quite -
it must be the last DMA device in the backplane...
Non-DMA boards *can* be placed after it
That's it in a nutshell. For a BA23, the critical numbers are
slots 1-3 == Q/CD, 4-8 == Q/Q. There are also some backplanes
with Q/CD in all slots, and some which are Q/Q in all slots.
Know thy backplane!

My mistake, I was misleading in saying that the cricket is in a separate
enclosure; actually it is in it's own box with only a cable coming out with
a connector that could fit in the modem or printer connectors (Serial device
comes to mind)
I'll do more web search before posting on the comp.sys.apple2
Thanks for the answers

Commodore going bust cut the CD32 down in its prime. In the UK it sold the
most CD-based software from the time of its release until around August
1994. Admittedly CD sales were not what they are now and it was up against
competitors such as the Mega CD, CDi, and PC-CD ROM.

It was not the first time such an idea was proposed for the Amiga. When
Escom bought the Amiga in 1995 they licensed the OS and chipset to an
American company called Viscorp (now known as US Digital). They hired a
number of Amiga personalities, including Carl Sassenrath, to create their
"Amiga ED" system. From what I have seen the machine was in a semi-complete
stage at the time of Escom's liquidation. There is a brief description of it
on my web site- http://www.onlyamiga.freeserve.co.uk/amigaed.html. I've also
got some interesting pictures of the machine in action that will be uploaded
sometime in the future.
Yesterday I mentioned the Siamese PCI card. I've just checked one of my
other email accounts and have been told that development has stalled. From
what I have heard Amiga Inc have stopped backing the project and there are
major concerns about the state of the "Classic" Amiga market (as always).

I guess by this you mean the constant flow of new COM interfaces/controls
and extensions... The Win32 SDK itself has been immutably around for quite
awhile.

RQDX1/2/3 support MFM not EDSI. It's of no help to you. Two possible
choices, find a MAXTOR2190 or find a EDSI controller.
