Digital Precision Ltd

Digital Precision Limited was a company run by Freddy Vaccha from premises in Chingford, London. According to QL User (September 1985 issue) Digital Precision Ltd was an off-shoot of CP Software. An interview with Freddy Vaccha (then aged just 27) appeared in QL User, June 1985.

They were best known for their large adverts in Sinclair QL World (several pages per issue) and the reputation for good quality software. Although some of their top packages breached the £100 barrier on the QL, with titles such as Perfection and Turbo people clamoured for their latest releases.
