Steve, if the heat is a problem on your setup, there are drop-in replacement switching mode regulators for the 7805 that can significantly reduce the oamount of heat dissipation. I used to have a super-Q-board that became so hot I ran into problems in summer - dropped in such a regulator and the board worked fine even without the heatsink.

Ah, that's version I've inherited, which used the old Sinclair plastic case.
