This is a luggable IBM-PC compatible system. It tends to offer an all-in-one solution for the perfect 80's business man. Back in 1983 it was the first Japanese computer completely IBM-PC compatible (hardware & software).
It has a built-in thermal printer (80/132 columns, 8.5'' wide) using paper-rolls. This was quite useful where you were on the move, but the weight of the whole system is also quite impressive. It is maybe transportable but surely not portable !
It was also possible to connect a more sophisticated printer through the Parallel port.
There is a 9'' CRT green display built-in along with a brightness control.
An interesting feature is that you can also connect the Sr Partner to an external color monitor, thus unleashing the fantastic power of this ultra-modern laptop...err. Maybe not, but you can at least enjoy CGA color graphics (640 x 200 with 4 colors, wow).
Apparently there were several models with different storage configurations : one 5''1/4 disk-drive (360k), two 5''1/4 disk-drives, one disk-drive and one hard-disk (10Mb, 20Mb)...
On the original disk, the MS-DOS ver 2.0A and Basic v2.0 were delivered.
Presented at the Las-Vegas Comdex in november 1983, the Senior Partner was proposed for 2495$ with Wordstar, Visicalc, PFS-File, PFS-Graph, PFS-Report and GW-Basic.
Panasonic, along with National and Technics were brands owned by the Matsushita japanese group.

I am looking for a cable to connect the keyboard to the computer on my Sr. Partner. I’m the original owner and it kills me that I can’t find the cable.
Any advice as to where to find one would be appreciated.
Thanks in advance.
