No clue...I have hundreds of Apple ][ boards and have never heard of
these (at least according to current memory).

I've got a couple EPROM programmer boards, but I don't know if I have
either of these. I know with one of them I got the software.

Interesting. Again, never heard of them. They sound like some sort of
terminal server system, maybe allowing an Apple to be shared? Naw, that's
silly.

No clue.

A very nice buffered parallel printer interface. Made life MUCH nicer
when you went to print a long multiple page document and didn't have to
wait for the print to end before you could use your computer again.

Probably.

Sweet. Does what it says, let's you link an Apple to a PC. Who is the
manufacturer on this? The only card of this type I know of was the PC
Transporter by Applied Engineering (still looking for one of those BTW :)
