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.
Please consider donating your old computer / videogame system to Old-Computers.com or one of our partners.
If anyone has the original disks for this system I''d love to get in contact with you and archive them for upload!

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.

The description says this supported 640x200x4 colors, but the specs say 640x200x2 colors (CGA standard). I assume the later is the correct spec. What was the video standard and resolution for the built-in screen? Was it 640x200 or was it Hercules or something else?
