Signals in brackets "(...)" aren't available on all ECB variants; the Schneiderware series doesn't support those signals. Moreover, the Schneiderware pin-outs are somewhat customized: Signals HALT, M1, INT, -12V, RESET are mapped to the "wrong" pin numbers, and some non-ECB signals SOUND, CURSOR, LPEN, EXP, ROMEN, ROMDIS, RAMRD, RAMDIS, BUSRESET are added, and, UBAT is listed as 5V in Schneiderware (normally it should be 2V..3V). Aside from the +5V, +12V, -12V supply voltages, the Schneiderware motherboard also has an "AC" soldering point; it's voltage/purpose and it's ECB-pin number are unknown-- it might possibly refer to the ACCU battery (rather than to a analog current AC voltage).
