Hi!
Does anybody know the pin-assignement of the RAM plug-in cards of the HP-48sx?
 
Does anybody know if there exist books about "Inside HP-48sx" and where to
order them?
 
Has anybody ever tried to open one of these plug-in cards? Is it possible
without doing any damage to it? (breaking the case, the sliding
connector-protection,... )
 
Do there exist any similary plug-in cards which could be used to avoid making
a PCB by myself? (I heard about Smith-Corona cards...)
 
                        Thanks in advance
                                Kaspar & Jean
