HP41 rom versions

[hth]

The DDD is the most rare thing known to exist.

I said that GFF machines have slanted keys, as I would assume HP used up they tall keys and switched ROMs in tandem, so to speak. I met machines with slanted keys that are earlier than GFF, so my guess was that it will probably not exist.

However, when thinking about it again, my old CV with slanted keys and GFF was made just weeks earlier of another CV that has tall keys, so if they mixed and matched a bit a they factory (factories?) it is possible that GFF tall keys do exist.

To complicate things, machines were repaired back in the days and mine was no exception, it was serviced two times in its early existence. Still going strong after the last repair around 82/83 by the way, now it is a 41CL and my most used machine again.
