So EL-506P, EL-512, PB-110 and PC-1250A all have a logo on the back that looks like the Greek letters Beta and Eta merged together. What does this logo mean?

[My guess: there was an industrial design firm used by both manufacturers and this was their logo.. but who were they?]

You can see it next to "Casio" on the back of this fx-602p:

This is the BM mark as explained very well on the epocalc site.
