It's not the Econet bridge (or at least not in _my_ Econet bridge), that 
has the normal PSU (I forget if it's a linear or switch-mode one) across 
the front of the case.

I've never seen the Pretzel (oops, Prestel) modem. I've got a scheamtic 
for it somwewhere, but that doesn't, IIRC, show the PSU. One day, I 
guess, I'll find one (although old Acorn kit does go for high prices on 
E-overpay...)
