Quoting Philip Pemberton <classiccmp at philpem.me.uk>:
The problem is that it has a 400W power supply... the
largest
autotransformer I can get locally is a rather nasty 300VA cheapie. :(
Did you try to post on comp.sys.3b1?
Probably somebody there would know how to convert the 110v to a 220v
power supply ...
