Apparently you have before you an RKS8E. Here are mentions
of the one by CJL, as quoted by Andy Valencia in 2011:

There also seem to be some diagnostics and stuff floating around.
I gather the word count board lets you read without interleave for
faster performance. There's also a change to support PDP-11
style drive addressing (i.e., more drives).
It's all news to me -- I had never heard of it.

Subject: DEC RK8E
So I have this DEC RK8E board set - and it has an
extra card. The
normal set is M7104, M7105, and M7106 - but this one has M7107 (called
"WORD COUNT" on the etch) attached to a very official DEC looking
cable harness with the connecting blocks.
I thought the M7107 went with the RK07, and I thought the RK07 was
never attached to PDP-8 systems.
Does anyone have any thoughts on this?
And I still want a couple of RK07s.
