Yeah, I'd actually really like to save this Micro 11's power supply but
I'm so bad at electronics that I feel hopeless trying. It'd be really
good, though, because I could then just neatly slide the micro into the big
cab when I feel like having it connected to all the other stuff, or keep it
in its little deskside cabinet for typical day-to-day stuff. It has to
stay very neat and presentable because these machines are actually part of
the decor of our den (and with my better half's enthusiastic approval,
which I realise is quite amazing of itself and don't want to blow)!
