Bought it from a small independent computer store in Glasgow, Scotland in 1989. Comcal was the name and it still exists!
Bought a vanilla A500, with no extras. Me and my two brothers all chipped in and couldn't afford anything else. They threw in a copy of Photon Paint. :-)
Over time we got a star LC10 colour dot matrix printer. 1/2Mb memory upgrade and external floppy.
Happy times. :-)
