TI 99/4a It  Lives! but extended basic?  acts   bizarre...
 
Great  got the  video cable 5 bucks   from the  UK  - -SOLVED!
 
Works  and fires up with out the extended basic  plugged in
but when I pluged it in and  selected the option  for  extended basic at 
book up just hangs  no
prompt on screen  etc.
 
I have the  screed  that TI had that was more of an  industrial  display 
rather than the  
screen that was converted TV that may have been earlier.. Heavy little  
monitor!   
It has a  strong mesh looking internal mask on the screen   compared to 
modern   color CRTS/
 
We also have  a  Epson looking  printer  with TI logo  to pair up
 
The  goal of  course is to  set  up as a display  at  SMECC Museum  with  
some of the other micros 
where it  can be demo'ed  I have the speech  module   too but have no idea  
what to do with that.
 
 Have a disc with cable but need  some  sort of an expansion  to plug it 
in. 
 
The adventure  continues... as  always   drop any  ideas  hits  etc  to 
us///
Learning as  we  go As I never used or  sold any of these  when in the biz 
back then!
