* Pretax profit 4.1 mln pounds vs loss of 3 mln pounds

* Resumes interim dividend at 0.75 pence per share

(Adds detail)

LONDON, July 14 (Reuters) - British bookmaking technology company Alphameric (ALQQ.L) swung to a profit in the first half, helped by growth in subscribers for its TurfTV joint venture and an improved performance from Alphameric Solutions.

Alphameric on Tuesday posted pretax profit from continuing operations of 4.1 million pounds ($6.6 million) in the six months to end-May, after a loss of 3.0 million pounds in the year-earlier period. Sales rose 17.4 percent to 19.9 million pounds.

The group, which supplies screens and software to bookmakers in the UK and Ireland, said it would pay an interim dividend of 0.75p per share, after no payout a year ago.

"Given an acceptable environment the group is well positioned to deliver a robust level of financial performance and to sustain a progressive dividend policy," Chairman Peter Bertram said in a statement.

The company said its TurfTV joint venture with racecourse association Racecourse Media Services had increased its subscriber base to about 95 per cent of licensed betting offices in the UK and Ireland after signing up BetFred in April.

Shares closed at 30 pence on Monday, valuing the group at about 68 million pounds.
