I've seen a similar system advertised in the past (must be more than 10 years ago - maybe 15) that was basically a computer program that backed just about every runner in the race if odds permitted a profit - however miniscule. This originated from Queensland from memory. The system may have been called TOP or TOPE systems - something like that. It ran on MS-DOS - so it pre-dates Windows too. The 10K price tag also sounds familiar.

This of course was long before the days of Betfair were you can make consistent long term (but miniscule) profits 'trading' a horse that its laying at one price and backing at another.

That bridge sounds more viable................................
