yes they do - I've been moving around too much the last few years so pretty much everything's been in storage. Hopefully all of my Sinclair and Acorn stuff should be going on loan to a local technology museum at some point for display - I hate the way everything's shut away in a room at the moment (er, actually rooms, loft and with the bigger stuff in the garage :-) nor me. I was given an Apple /// with a couple of ProFile hard drives a few years back and it started from there - I'm not sure what strange cards are lurking in the machines themselves at present. If anyone comes up with anything interesting on these boards I'll let you know; I've posted the same questions to comp.sys.apple2 but I'm not sure how active the group is these days. As far as the Z80 card goes a quick search of the 'net revealed a lot of 'Z80 card' boards but not 'Z80 card II' boards. I have no idea if the different name is significant or not yet :) cheers Jules
