ID these unknown apple cards please.

the first one is a bal-500 eprom programmer. it fits in a slot, but it's too tall to run with the cover on! it's not a pc card either. anyone with info on this? the second is a mpc peripherals ap-32 card. its full length with a language card connector, and empty socket for eprom i guess and 6 leds at the top and a toggle switch at the back. the third one is a full length card called an appli-card by pcpi. the last one is a full length card that looks older than most made by axlon 1981. it has a 34 pin header at the top of the card. lots of 74lxxxx chips. no other identification for this one. i can take pictures of these with my quickcam and make available on my page if need be. if anyone knows anything about these cards, give me a shout please. david
