I'd be comfortable with that *if* I couldn't acquire a terminal for the 
system - and I'd prefer to use a period terminal over an emulator even if 
it wasn't necessarily the correct one for the machine. It's all about 
recreating the original 'experience' as closely as possible, I suppose.

Personally I'm planning on keeping period storage around and using it for 
as long as I can. There will come a day when it's not realistic/possible to 
do that, but I'm really not interested in emulating a vintage drive with 
something that uses a CF card (say) if I don't have to.

Hmm. I don't have any problem with using modern hardware for the 
development side of it - but I'm not entirely sure *why* I feel that way; 
logically I fell like I should object to it :-)

I've got no problem at all with modern test equipment; I consider fixing 
the hardware to be a separate thing to using it, I suppose (even though I'd 
be inclined to say that I get far more enjoyment out of restoring vintage 
systems than I do once they're 100% operational).
