RE: HP25 RAM
Yes , I have tried to change but I have no results... with the second ram I have a strange result of 40 read in all of the memory program step... but I suppose that there are not perfect contact between chip and socket ( one row of pin is cutted and there aren't a firm stop of chip in socket) I'll try to solder the chip by wire for verify that the chip is broken and then I'll order a ultra low profile socket ...
