ISTR having to get the side covers off a HSC50 some years back, which I
think is the same cabinet as the 90 (certainly the same as the 70) and it
wasn't real easy. I don't recall offhand how I did it now,
I've never had any problems moving them so the necessity has not arisen.
I'll have a look at one of the 50's I've got here and see if I can remember.
