Yeah, that is great!
The boys can help me to compare a reverse-engineered old multilayer
layout against the x-rays from the original (no data, no schematics,
no gerbers at all available, but the urgent need for some spare
units....), can coil some dozens RF toroids and last, but not least
(if they aren't allergic against cats) can entertain our tomcats*
(who are not amused at the ugly wet wet thaw here...). I've heard
Clumpy and Kloumpios can meanwhile apparate and disapparate like
Harry Potter, thus there is no need to pick them up from the next
airport (would be MUC)?
Best regards
