LUCAS Problems with expansion memory

Myself and a friend are having trouble getting our LUCAS boards to work
with expansion memory.  He owns a starboard, I own a "rambo 2" (an
autoconfig, external, 2 meg memory box made by a company no longer in
business).  We have tried various 74xxx74's for U9 and U8 (including 
the two chip hybrids) and have built bus terminators, but to no avail.
Both our systems freeze just prior to putting up the picture of the
hand holding the workbench disk.

I'm not an expert in amiga hardware, but I assume that something is 
screwing up (how's that for a technical term) in the autoconfig.  

I have the original A1000 hardware manual, and noticed that there is a
section on autoconfig.  I have not yet read it though.  Before I do,
could anyone tell me if it is accurate (or if the autoconfig spec has
changed?).  Since the problem might be something that happens right after
autoconfig (there'd be no way of telling), what happens immediately after
autoconfigging a memory board?

Any help, hints or wild ideas would be appreciated.
