I'd concur with that correction. I used to work for a high street Chemist chain who had a dedicated photographic shop and when Cine was in decline they employed me to run their new 'Computer' section. It was mainly BBC, Sinclair, Dragon, Oric, Amstrad etc. but the first 'IBM' clone that I bought in was a Ferranti. I did eventually sell it but I remember that it had a serious problem inasmuch as it had a 'daughter-board' which fitted below the main board and with the showroom being on the first floor, the vibration occasioned by passing traffic caused that to drop out of its slot !!
