I would recommend to everyone on this list to check out the web page at
http://www.wam.umd.edu/~ltduck/ti92/ti92.html
because that has had a huge amount of info. on the internals of the '92 as
far back as Jan. of this year. I'm amazed that noone bothers to look around
on the web, 99% of the questions asked on this list can be answered with a
few minutes of searching.
On another note: didn't anyone think to just try different keys in Ftris?
Takes about 20 sec to figure out that C and STO> are the ones you want.
