tonewheel,
thanks, interesting i was gonna put in an old 40gb
then AJ said for that, i'd need to upgrade my EPROM chip as well
so i then found a Travelstar 5gb drive on an old laptop with Win95
i think this is plenty room for my midi, styles, registrations etc.
i have ordered the original mounting plate, ribbon, screws (no HD)
so i think i'm all set now..... thanks for your suggestions
