The original M-Series machines were the 2105A and the 2108A (9-slot), which
sound like what you have. The early machines didn't say "M-Series" on the
front panel, and had a different lock than the later models:

Early models had the power switch on the back panel, while later models had
it behind the front panel.
It sounds like you might have a later model M. It would be helpful to see a
closeup of the read card cage (with readable labels), as well as the front
card cage. The front card cage is accessed by unlocking the panel and
removing the cover on the right side over the card cage. That's where the
memory boards live.

I can tell the front panel appears to be the same as any of the other HP-1000
series.
What I?m trying to figure out is what the actual CPU configuration is without
disassembly (which I still need to figure out) so that I can actually examine
the boards.
Thanks.

Can you provide a picture of the front panel?
2113 implies a 21MX-E; the nine-slot version is a 2109 while the fourteen-slot
would be a 2113.

Subject: Identification of an HP minicomputer
Hi,
I have sitting in my pile of stuff an HP minicomputer that I?m trying to
identify (at least in terms of exactly what it is and what sort of
configuration it might have).
As far as I can tell, it?s an HP-1000 M-Series minicomputer (that should
hopefully get us *some* details). The ?asset tag? lists the part number as
2113023-108. Looking at the back there?s space for 9 I/O cards (5 are occupied).
So my question is which of the several CPUs could this be and how do I tell
(for example) what the configuration is (e.g. how much memory, etc).
Yes, I have looked on bitsavers, but short of disassembling the box to look at
the (at least) 2 boards that are below the I/O slots, I can?t tell what?s there
and I?d like to see if there?s a way to determine what this is without
resorting to disassembly.
Thanks.
