HELP!!!

I have some data for a really urgent project trapped in files with these extensions. I have found out that .TD is a turbo debugger configuration file for DOS and .SP is a splint compressed archive file (UNIX) but have not been able to find out how I go about opening them. My computer appears as confused as me (traitor!) and it's on-line programme search came up empty handed.

I really need this data so If there is any bright spark out there who can help me please please do!

Many thanks !
