Hello, James,

That sounds more like the stuff for caching RAID controllers.
And I seem to recall that some *very old* AS/400s had packs of AA or AAA cells, maybe even in the control panel module itself.
Yes, the P02 for example. And a Fsomething I once had, and needed to scrap because of a defective main planar-or-PSU.
I have limited first hand experience with different hardware specimens, but apparently the AA(A) pack for retaining the TOD clock is a thing for very old CISC machines only. Definitely not a RISC 170. See my remark about looking online for pictures. :-)
:wq! PoC
