Here is a link to a document with photos: pgs 3-4 show extraction of circuit boards containing memory chips from the CMSU of a Honeywell 6022 CVR.

The physical outer shape of the 6022's CMSU is somewhat different, but it has similar "circuit boards encapsulated within a thermal barrier substance housed inside a strong enclosure" construction.
