''[note 3]'' In programmable mainframes, A24 is | ''[note 3]'' In programmable mainframes, A24 is clamped to not exceed +3 V, indicating to programmable plug-ins to use TS2-TS9 as GPIB lines and a modified readout logic using only TS1 and TS10, with TS1 being active in time slot 1 as in other mainframes, and TS10 being active in each time slot. Programmable plug-ins source at least 100 μA into TS10 (A29) indicating to a programmable mainframe that the alternative time-slot scheme is to be used. | ||
