I found a pile of cards, and sorry in advance for the poor memory, but I am
curious about them.
They are long ISA cards with a single nothing special (maybe DB25?, I
forget) connector on the metal card end bracket. They have an NCR 80186
chip among others, and APL 186 may be marked on the bracket. Franklin
Networks is on the card too (I think). I sorted them out of a box of cards,
then put them back since I didn't have a clue about them.
