I have other 45/70 drawings that i haven't pdf'ed
I need to see if they are different revs than what I already have
Ohh... I'd be very, *very* interested to see versions of the /45 drawings other than
the two sets that are commonly available!
I've been collecting/compiling detailed information about ECOs and board revs for the
KB11-A (for example, the one that launched this thread!), and looking at diffs between the
two available drawing sets has been a valuable technique for shaking out hints and clues
about things otherwise undocumented. Having more to draw from here would be *super*
helpful.
A fairly complete summary of things puzzled out so far, for those of you with /45s who may
be interested, is here: https://fritzm.github.io/ecos.html
