E30/E50 guts, but with new loading mechanism. EP10 and EP11 are pretty much identical with just a slightly different exterior panel design.

Can load a either a single AA or a NiMH "Gumstick" into the battery compartment.

Slot-in design, rather than pop-out.

MD Mechanism Type: MT-MZEP10-129
Optical Pick-up Mechanism: ODX-1A
System Control IC801: RU6715MF-0004
ATRAC IC: UPD63730GC-9EU - Shared with the MZ-E30 it does not contain an ATRAC encoder, making version identification difficult. Based on the MZ-R30 released around the same time as the E30 it is most likely an ATRAC v4.0 device
