The latest incarnation with "backdoor" was the most important update to the clamshell series.

We found out about that "mis-design" years ago when my girlfriend's HP-19B started to need a tape to stay closed....

I picked up a back-door version in the meantime but I suppose there is no back-door HP-28?
