The problem may well be that the Tanzania on-board video doesn't do 
composite synch above 640x480.[1], and the adaptor probably just 
takes CSYNCH through and ignores H and V synch, merely emulating the 
17" multiscan monitor sense codes. 

I had a really rather wierd time getting an old fixed frequency workstation 
monitor working with my 4400[2], but finally cracked it by using the 'Mac 
Composite Adaptor' from Griffin (http://www.nashville.net/~griffin). They 
told me what I needed promptly and put me in touch with a UK distributor. 
The adaptor takes the Mac H and V synch signals and makes a CSYNCH. It cost 
about 20 quid.

[1] Not, as it happens, the whole truth. If you boot with the 14" monitor 
then switch to a higher resolution using the 'Multi Resolutions' contol 
strip module(highly recommended for this sort of faffing about) , then plug 
the bigger monitor in to the mac you may find it happily cntinues to do 
CSYNCH at the higher resolution. Not a good long term solution though.

[2] And all dur to be repeated now I have pulled a 20" Hitachi out of the 
skip.
