The "Replace RAM, Press ON" feature discovered when a RAM card falls
out, is knocked out, or is pulled out of an HP48SX  IS  documented.
It is in the paragraph marked Caution on page 644 of the HP48 manual, in
chapter 34 on RAM cards.
Mind you, this is clearly not a paragraph that is well-known. When I
read about this feature, I mentioned it in the HP-41 Emulator card
manual that I was writing. I was told that they would have to check
whether this could be in the manual, as it might be a non-standard
feature. I protested it was standard and in the manual, so thay looked
it up and left it in the emulator manual too.
As Roy Smith says, this is the sort of feature that leads to fanatical
HP loyalty !
