Not a single reference, but these two directories should provide most of
what you need:
http://www.bitsavers.org/pdf/hp/1000/
http://hpmuseum.net/exhibit.php?hwdoc=108
The CE Handbook, Loader ROMS, Interfaces, and Standard Memory manuals will
all be useful.

OK, thanks.
Is there a sheet somewhere that I can use to decode all of these part numbers?

Sorry, I mistyped. 12746A is a 64KB (32KW) memory module.

Except that I don?t have a 12745A memory board, I believe it?s a 12746A which I
think I saw was a 16K board.

Thanks all!
The trick was opening up the front panel (I?m used to keylocks that are only
electrical and not just physical).
Here?s the HP label with the options:
CPU 2103
MEM BP 1713
IO BP 1727
Accessories
12992B
12944B
2102B
12897B
12892B
12746A
In opening the panel on the front card cage, I saw that it only had 16K of
memory. :-(
I?ll see about firing it up and if that goes well (anyone have suggestions for
this type of mini?) I?ll see if I find more memory and suitable peripherals.
Thanks.

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.

It?s a 9-slot variant that says HP-1000 M-Series on the front panel. From what
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.
