The Philips Pronto line, started with the TSU-1000 in 1998ish. And has ended in 2009ish. All of which had a touch screen, started off as 4 shades of gray, and ended with color, I forget how many.
Nevertheless, the Pronto's are still a good power house for remote controls. Personally I will prefer the Pronto over most universal remotes now a days, including the professional installed ones.
If you have the technical experience in design and small programming. You may want to start off with a Pronto TSU-7500. Or TSU-9400.
