Isn't the "tall" front panel board primarily different because it includes a
connector to go to the MPP port on the cpu? I'm not real up on that, but I
think it was only used on the F series, and used to provide high speed
memory access to an external device? Something like that sticks in my head.

Subject: Re: HP 21MX E-series front panel keyboards
Take a look at this doc:
http://www.bitsavers.org/pdf/hp/1000/1000_MEF_EngrRef/
92851-90001_Mar81_8.pdf
There are drawings of a shorter 2105/08/12 front panel PCA 5060-8343
and a taller 2019/11/13/17 front panel PCA 5061-1343.
Does that help at all?

Hi All,
How many types of front panel keyboard were used with the 2113 E-series
CPU?
I have one in front of me that has two ribbon cables that run from the
keyboard PCB to the CPU PCB (one from the top edge of the keyboard PCB
one
from the bottom edge) but I seem to remember having seen other 2113 CPU's
where the keybaord PCB is smaller and a single cable runs from the bottom
edge of the keyboard to the CPU PCB.
