this is continental chord notation.

B = H

Bb = Ais or A# = B

# = is so that C# = Cis, D# = Dis, F# = Fis, G# = Gis

b = s or es so that Db = Des, Eb = Es, Gb = Ges, Ab is As

I think that's the lot! now go figure the chords!

On Technics if it's not in fingered, it's in pianist. On Yamaha they have a mode that combines both fingered and single finger chords so you can swap between either.
