In David Ornstein‘s premier issue article (SQ Winter 82 p. 29) Using Extra Keys on Big Keyboard, add a symbol A atop the D1 lead toward the right-hand edge of the page. The list of connections refers to this symbol. Also, the D3 (ANODE) legend applies to ZX80s, use D6 (ANODE) for ZX81s & TS1000s. Finally, change Jun.81 to Mar.81.
