I'd like to use it either for an A4000 (with PS/2 adapter) or for a Elbox towerized A1200. Elbox's keyboard interface works with AT and PS/2 as well as with all the big box Amiga keyboards, so it's really not important what particular model you can test it with. Anything from A2000 to A4000 should do. ;-)
Anyway, as this seems promising, I declare interest in this item, provided the above test succeeds.
