Found some printer cards for Apple ][ computers

At least it's what they appear to be... Found at a local electronic "computer" store: several printer cards for what appears to be Apple ][ computers. (I'm not an Apple person, so I don't know the bus layout.) The connector is a 50 pin edge-card (25 per side) and there is a 20 pin header on the board, to which attaches a companion flat cable with a conventional Centronics-style 36 pin connector at the end. The cable is 3 feet long, and it looks like it was meant to exit the enclosure and plug directly into a printer. There is an on-board 2716 eprom (I might dump the contents at work to see if there is any manufacturer info inside.) There is absolutely no manufacturer name or info on the board other than what appear to be part numbers (I think): "APL B" and "SP-201-EP-0" in the silkscreen and "H-002" in the copper foil. Parts are all SSI (74LS00 series) with date codes around 1984. They were free, so if anyone wants one or more, let me know. All I ask is shipping or "you pick up." I'm in Corvallis, Oregon. Oh, and I should say for emphasis: I HAVE NO IDEA IF THEY WORK and NO WARRANTIES EXPRESSED OR IMPLIED. Contact me by email if you want them. I don't have any Apples, so don't have a reason to save them. Just didn't want to see them dumpstered. Gary.
