The Lynx is off the endangered species list and to judge from last week's Lynx User Show in Birmingham it's getting the most attentive of intensive care.

Owners of the 48K and 96K models of the ex-Camputers home micro have put their heads together to give Lynx users something to look forward to, and the first results of this self-help movement were on view at the show.

There was a full RS423 interface, a sideways ROM unit, a trackerball, a prototype speech synthesiser, and a range of brand new software to run under CP/M.

This is only the beginning. In the pipeline are a rehashed Basic ROM, a user-defined scroll routine, an advanced technical manual, and various graphics developments. Some may be seen in London in the summer - the User Group (contact RB Jones, 209 Kenton Lane, Kenton, Middlesex) plans another show later in the year.

"The main aim at the moment is to get everything on a very sound business footing," said Jones. With Anston Technologies concentrating on the 128K model, his group has permission to develop the smaller Lynxes on a kind of co-operative basis and the approach is working well. "By releasing circuit diagrams over the last three months we've got more interfaces and add-ons than Camputers ever produced," he said.

Each member of the group is sent a questionnaire, so that Jones can pin-point their strengths in various areas. The most ambitious project involves the Lynx's graphics - "The Lynx has enormous untapped potential buried in its depths," Jones said. "We're attacking the video side very heavily."
