[QUOTE="easysat, post: 1840, member: 175305"] I had a look in some old Amstrad DRX100s. The really old ones have the ST20TP2 channel decoder chip and a socketed chip marked "BSkyB". The newer ones have the ST20TP3 chip which has the Videoguard access module integrated (according to the ST Microelectronics website) and no chip marked "BSkyB". This seems to confirm what the Sky insider said. The BSkyB chip must be the Videoguard descrambler. Curiously it is just a MACH215, a type of standard programmable logic chip made by AMD. (Although Lattice Logic has since taken over this part of AMD's business). The other thing I noticed was a socketed chip from Integrated Silicon Solutions Inc which seems to be some sort of secure EEPROM memory. I wonder if this contains the serial number of the Digibox?
