Hidden 'staff-roll' in Sony F1-Mk2

Cool, I wonder if any other MSX has "easter eggs" hidden feature like this. Good find!

Thank you for this info I had to test it .
To my surprise my hb f1 did not power on.
needed to find the reason,spend a couple of hours
To find out that C184 was short cirquiting
Thanks again

Looking at a japanese keyboard the hiragana found on the p and y keys are "se" and "n". Now, "sen" can have many meanings, but I think the following kanji might have been intended:

撰 -> anthology (of poetry, etc.); compilation; collection; selection

There are several words that start with that kanji, but again, the most probable in this case:

撰者 (senja) -> author; compiler; editor

So, p and y map to "se" and "n" which is the reading of the first kanji 撰 in the word 撰者 which means "author; compiler; editor".

Just an (educated?) guess though, I might be completely wrong

Makes sense.

Cool. This is also present on the HB-F1 II, and at the end of the credits it plays a voice sample which sounds like "It's a Sony"
