Gosh, haven't thought about those for years. I had one (I worked for ICL) soon after they came out, amazing telephone capability - for the time - the WP and spreadsheet, and the email capability were basic though adequate. The microdrives were, to say the least, temperamental

The picture shows one with a colour monitor, not that common, most including mine had a monochrome monitor. Lasted for years mine did.
There was a story, true or not I don't know, that pre-launch a delivery went to Australia for ICL staff there. Unfortunately it somehow was delivered to one of ICL's customers. They opened the crate and had a look and played with the OPDs and were so taken with them they contacted ICL Australia to place a large'ish order. Of course ICL Australia didn't know anything about them and hadn't seen any at the time.
