A fast 16 bit CPU but a weird way of accessing memory made the thing really
...
 slow IIRC 

It had the potential of being a significant first 16 bitter.  The muxing
of the bus
down to 8bits and really cost in speed.

...
 I think it was a costly & painfull venture for
TI... 

Ti was infamous for that.

...
 I am still looking for the expansion box / floppies 
for these...these are
...
 rarer because so expensive back then... 

Yes, but there was an aftermarket that was significant historically.

...
 I have accumulated too many and some will go in garbage
at next
inventory/cleaning...Ill keep the "inbox" ones... 

NOTE: the video chip is extinct and same for a few other bits like the
GROMS so even if you strip them for the boards there are people
that might want them just for that.

My 2 cents...
