I found my top of the line Wizard (nee Zarus) the other day and fished out some batteries and turned it on. So quaint, so challenging to read. What I liked about it is that it worked for years (and still does what its supposed to) for years without updates or upgrades.<p>I think if I was going to do a CPU swapout I&#x27;d try to use an ARM chip, that said construction was not designed for remanufacturing :-)
