Jay: Saw your message dated Oct 1, 2003 about the TI system. Did you get it running? I too, have some TI hardware and I've written some cross support software that may be of interest (cross assembler, cross linker and a simulator). You can access the stuff at: http://www.cozx.com/~dpitts/ti990.html Good luck. -- Dave Pitts PULLMAN: Travel and sleep in safety and comfort. dpitts(a)cozx.com My other RV IS a Pullman (Colorado Pine). http://www.cozx.com/~dpitts
