I think, with my capability for pushing the wrong button at critical 
moments, I might be safer to stick with ext2 then.

Quite true.

My motherboard is a 350MHz K6.    If I have to upgrade it, I won't be too 
upset, but the 350's fast enough for what I need so I there's no point fixing 
it if it ain't broke.   And I guess one big advantage is, I can afford to 
risk breaking it     ;)

Btw, I initially set up that DOS/Windoze drive I was talking about on my 
spare machine - a 75MHz  AMD  K5.     So what, it still works!
