It can be quite confusing when you tack a post onto an expired thread instead of starting a new one.

The simple answer is no. Read the requirement for supporting a Pentium processor. My old Pentium 2 works better as a key fob.Among other things, you would have to write your own custom operating system from scratch with no support tools.

Depending on your requirement, a PIC or AVR microcontroller would be much more likely to work. If you need something more processor-like, then consider a design based on the Z80 or the 8051 core.
