they are the same. the only difference "MIGHT" be whether they came as a kit or assembled.
usually a label on the bottom indicating the latter. both came with assembled PCB boards
with the kit requiring final wiring to switches, etc. there were cable assemblies to facilitate
the signal connections.
the PCB boards came in variations - BIG letter (A, B , …) in the middle of the PCB
with some changes in parts and certain cap locations. as a follow-on to the Dh101
it was totally metal films,
