Heh heh - well I grew up burning my hands on 240V. You get used to it after a while.

To start with you’ll need a floppy disk controller IC - either an 8271 or a 1770 - and a copy of the Disc Filing System ROM. Different versions supported different controllers IIRC. There may be extra installation work involved if it’s a model A.

 Ian Primus probably has the necessary EPROM or I can burn one for you if I can find where I stashed my EPROM stuff during house moving.
