W93 - 0,1 - 82

WC0 - 0,1,2,3 - 82 - SBM3

Rosewood AF (Janus) - WDZ, ZDZ

WBZ - 0,1 - 82 - ????
WDZ - 0,1,2,3 - ??? - EB01
ZDZ - 0,1,2,3 - 82 - EB01

Note: it was just noticed that when reading the Preamp directly from ROM on one drive (ZF5), the preamp shows as 82. Yet, via ctrl-l in terminal, it shows C2. This seems to reinforce the idea that the preamp versions are likely interchangeable.

• This has happened 2X, thus far - Using a Rosewood AF (ZDZ) set of heads on a Rosewood A5 (WDZ) patient allowed to read, but could not write SA.
• As noted below by @arthur, AF-WBZ donor heads worked for A5-WBZ patient, including the ability to write to SA.
