Roughly what length are the cables? And do you know if they do anything 
special internally regarding shielding of the data lines?

I think I should probably wire one up, and I have various old printer 
cables etc. laying around to use for donor parts, but I expect that data 
skew is a problem over any significant distance.

(I'm not sure if a clone of intersvr exists for Linux, but I *think* I can 
run dosemu and map it to the native parallel port anyway)

cheers
