The VME bus is an old stalwart of military and aerospace applications. Coincidentally the edition of Dr Dobbs Journal, containing my BeRays ray tracer article also had an article on NASAs Mars rover and the MIL-STD-1553 bus and was published at the same time I was working on MIL-STD-1553 on a VME rack.
In these blog entries, I revisit and investigate the VME bus on SGI systems.
