Thank you all for your help with this. 
I actually had EXB, but never got a Floppy drive (too much $$ for a 10/11 year old kid) so all this is 'new' stuff to play with for me 
 
Edit: JOY!! Tex-Hogger, you made my day!! FWEB501.dsk does the job brilliantly ... this will certainly help kill the dead time at work 

 Many, many thanks again.
Not a prob!!  I grew up with the TI as a kid back in the early 80s and still have my original system, PEB etc.  I also have been collecting a few parts and pieces here and there.  When I fond V9T9 I was sold on emulation.  Now with MESS I can do almost eveything I use to back when I was a kid.  If anyone has any questions about the TI-99 I may be able to help, but there is a great online users group on Yahoo that has many good people that can answer all most any question.  Also there is a great FTP site that has a larg amout of data for the TI.  
Now if we can get the Geneve 9640 working on the GP2X I would be truly impressed.
Enjoy!!!
