I'm not really familiar with SAGE machines. They were not as well-known in the UK, I think, being upmarket from the Apple ][ and IBM PC, both of which were eye-wateringly expensive by UK standards of the time. Also, they were terminal-based things and even back then I was interested in boxes with graphics. :-) -- Liam Proven – Profile: https://about.me/liamproven Email: lpro...@cix.co.uk – gMail/gTalk/gHangouts: lpro...@gmail.com Twitter/Facebook/LinkedIn/Flickr: lproven – Skype: liamproven UK: +44 7939-087884 – ČR (+ WhatsApp/Telegram/Signal): +420 702 829 053
