FYI OG Cherry APL is outdated
I'm not surprised, it seems like a lot of Cherry's regional layouts/languages were incorrect or outdated in some way. What's actually outdated on them, out of curiosity?
Is it any more out of date than the Hammer layout? From what I can tell, the differences between the two are very minor, and in some cases Hammer took legends from entirely different keys to adapt from the DE ISO of the originals to ANSI. For example, the APL legends on \| are from the German >< key next to left shift.
I figured it might be a better source for tracing, since Hammer's legends are traced from these to begin with - taking them from the source should be ideal. Any modernisation would have to be done with the Hammer traces anyway. If it's not needed or wanted, no problem though! Just thought I'd make the offer.
