@knc1: That's basically KT3+, right? i.e., anything that was originally shipped on >= 5.8.x (KT3, KOA2, PW4, KT4, KOA3).
The "final" "friendlier" model being the KOA.
Or did the KOA2 slip through the cracks? (I seem to recall those being hard to open without killing 'em, anyway...).
TL;DR: In which case, yeah, I can point that out that when the serial approach is mentioned, good point
