Not just in principle, in fact the Master Econet module and the
Archimedes one are the same module. Same length of pins. Same part
number. Yes, they do foul podules, which is why the multi-I/O podule
was made the size it was -- so it didn't interfere with an Econet
module. However, HCCS solved that problem for their own modules, still
using standard length pins; they re-laid out the PCB and mounted all
the components on the underside, thereby getting just enough clearance
:-)
