more on ibm paradise card

Ok, took a closer look at the paradise card in my IBM 5150. It's actually two full length boards, stacked together with standoffs. The "main" board has on the back bracket (from top to bottom), a two position slide switch, a DE9, an RCA jack, and another DE9. Has a sticker saying "DM104338", I'm guessing a serial number maybe. Etched on the board is "Assy 15100". On the second board in the stack, it says "Paradise Systems, Inc." and "Multidisplay card". Silkscreened on the board is "Assy 15200", and "CADAC M01". Also has a sticker, "DM504338", and here's the kicker... hanging off this full length "daughter card" is a ribbon cable that goes to a 2nd bracket with a DB25F connector, I would guess parallel port. may be a combo MDA/CGA card. Can anyone fill in any more info? Jay West
