It's great to see one so young (going by your profile), so passionate about such old equipment.
As an old fart who remembers doing component level repair on those Power/Sweep boards, floppy drives and motherboards when the exchange price of a Power/Sweep was AU$450.00, it makes me appreciate somebody taking the time to go this far.
At least when I'm gone there will be those who care enough to keep these curios going.
