Anyone know how to interpret Makino BB numbers? We're lookin at:

0302
50

your best bet is to ask Makino-san himself.

Nah, but these people do. https://www.cc.rim.or.jp/~mackino/

I tried a few times to find their website, and never had any luck. Thanks.

Edit: That's a lie. I think I was on the site just the other day. But I lost the link and didn't remember.
