Dwight ----------Reply: And, just to make the GI list complete: AY-3-1014A* (1) CMOS, 480kHz/30kb, AY-3-1015* (1) NMOS, 480kHz/30kb, Input pull-ups AY-5-1013 (2) PMOS, 480kHz/30kb AY-5-1013A (2) PMOS, 640kHz/40kb AY-6-1013 (2) PMOS, 360kHz/22.5kb * = 1 1/2 Stop bit capability PMOS = +5 and +12V, NMOS = +5 only Two sets of basic characteristics (1) & (2), pin compatible. m
