'''DEC Alphabet''' is the name given to the cut-down alphabet used by [[DEC]] to number things such as the contact fingers on the edge of [[DEC card form factor|standard DEC cards]]. It runs:

A,B,C,D,E,F,H,J,K,L,M,N,P,R,S,T,U,V

I.e. leaving out 'G', 'I', 'O' and 'Q', which when poorly printed might
be mistaken for '0', '1', etc.

It stops at 'V' because [[FLIP CHIP]]s, and later boards in that system, only had 18 contact pads on the edge fingers.
