Turning heads in London's West End last week were three Prism Topo robots making sedate progress from Bond Street tube station to the new premises of Computers of Wigmore Street. The march of the robots marked the opening of the store's new shop at 104 Wigmore Street; they'll be followed over the coming weeks by demonstrations of the systems on sale or in the pipeline. The shop has a reputation for being first - for example with Memotech systems and with retail Microdrives - and when owner Michael Litvin says he hopes to show off the Enterprise, the Commodore 16 and Plus/4, and perhaps the Acorn Business Machine, there's a good chance they'll be there.
