The 4050E01 is a ROM extender for the 4051, 4052, and 4054.
It has eight slots for either ROM Packs or interfaces. The 4050E01 automatically recognizes the type of 4050 series computer to which it is connected. The ROM Packs and printer interfaces used in the Expander must match the computer type.
The 4050E01 uses bank switching. The Motorola 6800 in the 4051 only had a 64K address space. The 4052 and 4054 have separate code and data spaces of 64K each, but still not enough for all the ROM packs in a flat address space.
