5150/5151 Video Card??

[Fred Cisin]

That one has a lightpen connector, which his dorsn't.
Not usually important, but it might have other differences, such as 
different functions for the switchrs.

There were some MDA boards without printer.

Plugging 5151 into CGA could damage the 5151.
Even plugging it into EGA with wrong switch settings could.
