The connectivity between the transducer and the PC is via the serial port and the application runs in MS Dos if i recollect correctly from what i saw at MG road Petrol punp today. So i recommend a p1/p2 system with 64Mb ram and say a 4GB disk This configration is available at Big Apple for Rs 3500/- (less Monitor +2500) check it out
