'ICE' Apple /// cards

This Apple /// I picked up today has two boards in it: 1) Labelled "ICE KONAN ADAPTOR", with a ROM and 6116 RAM chip on it + a few 74xx logic chips. It's got a 26 pin header on board. 2) Labelled "ICE multiplexor host adapter". Has a 20 pin header on it, plus two (empty) 24 pin IC sockets (and a handful of LS logic). Any ideas what they are? The first *could* be a clone Profile controller I suppose - the owner swore that the Profile I got went with the Apple /// and not the Lisa. I get the impression he hadn't looked at either machine in years though so I suppose he could be wrong. The system itself has a large RAM expansion board in it, but otherwise looks to be stock. cheers Jules -- "We've had a lot of loonies around this place, but you're the first one who thought the sunrise was made out of stale beer.
