Although the LP120 has the potential to program nearly every programmable device in existence, the current list of devices it can do is rather short. If you have experience in hardware design and are familiar with Motorola assembly code, then you have the skills to design your own programming modules and write drivers for them.
If you decide to design a programming module you should read the Notes on Building your own LP120 Programming-Modules on Data & Documentation page. If you find you need some help please contact me. Email me with any questions you may have.
