COM 2 SELECTION IN IBM PC-2 EARLY MODELS
|
|
|
|
|
|
It has been reported that there are a number of IBM PC-2
|
|
motherboards, earlier models, that do not allow COM 2 selection.
|
|
|
|
There are two distinctly physical features:
|
|
|
|
1. The motherboard is brown in color.
|
|
|
|
2. In between banks 02 and 03, the silkscreen "YB" exists (see
|
|
figure 1).
