I have been given a PDP 11/04 (at least that is what the front panel says and it does have an M7263 CPU board) to look after for a few years while the owner is away working and am quite keen to try getting it operational. I have no idea when it was last run so will be going through the full capacitor reforming process/etc. I am not a DEC expert (they are not really common down here in New Zealand) so am relying on a lot of the info on the net. Everything I have read suggests that 11/04's are in a BA11-L chassis with an H777 power supply ( http://www.brouhaha.com/~eric/retrocomputing/dec/pdp11/chassis.html). This unit is in a BA11-K chassis with an H765 supply. Is this normal or is it possible that the machine has been repackaged at some point in it's life? Regards Andrew
