Features: Based upon E30/E50 electronics but with a new ``head loading'' mechansim that allows an MD to simply be pushed against the top of unit, whereupon the door pops out of the way and permits disc insertion. Battery compartment accepts either a gum pack shaped Nickel Hydride cell or a single AA cell. The former provides 4 hours playback, the later 5 hours.
