unebonnevie Posted May 5, 2019 Share Posted May 5, 2019 Hi, Would like to know what is the maximum current an Apple II/IIe slot can draw on? I read in the past somewhere on the net that it would be 500mA? Thanks for any info on this! Quote Link to comment Share on other sites More sharing options...
ChildOfCv Posted May 5, 2019 Share Posted May 5, 2019 There is no individual maximum. The power supply rates at 2.5A available for the system. The onboard stuff takes about 2A of that, leaving about 500mA for the TOTAL of the expansion slots. They list the driving power of each bus pin by number of LS-level gates that they can drive, in an attempt to be helpful. See page 172 of the IIe Reference Manual. http://www.applelogic.org/files/AIIEREF.pdf Quote Link to comment Share on other sites More sharing options...
