Reading up on the RC Piccoline I realise I misremembered. Each 4 computers shared one drive unit. So not quite terminals as I remembered. Did the UK variants have some of the same quirkiness? I see they have a "network server" (XN20) listed.
I was stuck on the rare 3" size. But lived in a fishing town so I could get them a little cheaper - they where commonly used for plotters on the boats.
Thanks for that hint. That was interesting.
Impressed by writing a website on a CPC. You have been a true die-hard. I first saw "the web" with Mosaic on a SUN Sparcstation in 1993.
