I am NOT interested in another, but, 
If you are there again soon, start with a quick look at the connectors in 
back.
It should have an FDC board, with a DC37F
It should have a video board, either:
     CGA: DE9F, RCA F 
or  MDP: DE9F, DB25F (printer port)
Any other external connectors are added board, maybe IBM, maybe 
aftermarket.

That's almost all that you can tell without opening, unless it has certain 
other deviations from usual, such as a DB25 block-off and/or a round 
block-off on the back panel, or a white power switch, etc.


If/when you open it, the first step would be a detailed inventory of any 
OTHER expansion boards, followed by a glance at the on-board memory - 
early machines had four rows of 16K RAM; later used 64K RAM.  Original 
drives were Tandon TM100-1, followed soon thereafter (DOS 2.00) with 
TM100-2.  Original power supply of 5150 was 63.5? watts.  Some of the 
early power supplies were black.
