Hi Sudhir. Hope you get a result, there, Mate. I should imagine that a suitable "generic" hub may be pressed into service (although I don't have the details to hand myself, unfortunately). But, if the hospital can't afford to support equipment like this, I can't help wondering (and please forgive me for wondering) why they bought it in the first place?
PS: what's the name of that place in the S.E. of Nepal where
everything electronic is available at bargain basement prices?
