I've been scanning the web in search of any code listings for these processors.
Intel once had a library for some of these but it seems most is lost.
I've found reconstructed listing for the Intellec4/40. I've seen just about
all that existed in Intel's manuals.
I even found an interesting listing

Ah, so it has, under both the BMC and the OKI names. I was going to
try it with imgdisk and 22disk eventually, but I was in a KF
experimentation phase.

From the various comments,
Interestingly(?) both my RK05 and RK05J had an assembly of 3, not 4, 2/3rd
AA NiCd cells for retract, completely decayed of course. I replaced them
with 3 discrete tagged NiMh AA cells (plenty of headroom) soldered and
shrinkwrapped. They work fine, lots of retract force. The clip which holds

Yes, the HP 7905/7906 does this for example.
