Ok I opened up a Legend Large Processor, FM2 (which means Release 2.0, It has two batteries rather than the Tolkin capacitors. The first battery jumper is HDR3, the second is way to the right by the same type of battery (PMB 3.6B). It is not marked with a number. Your processor is probably an older generation tahn mine - and you are getting out of my knowledge range. Travelling Tom may be right in that you will need to use a DOS version of SPM - and the WinSPM versions you downloaded will be useless. I don't know where to get a copy of DOS SPM - I don't have one.
