First off, if you don't have a little connector at the TOP of the display
card (it is a FULL LENGTH) card, then you have neither one (or you are
missing some connectors... ;-) ).
If you have ONE little connector at the top, bridging the cards, then you
have the All Points Addressable adapter. It is part number 8654390,
according to the info I have.
If you have TWO little connectors at the top, bridging the cards, then you
have the Programmed Symbols adapter. It is part number 8654381, according
to the info I have. The PS adapter was designed for use in emulating the
original 3270 graphcis displays, which were not all points addressable, but
instead used dynamically downloaded character sets. (Yes it is possible to
do bit image graphics this way -- up to a point. It is butt-ugly to program).
Of course, if you had a diagnostics diskette for the beast, that would also
tell you what you have. Un
