Old Type-1 IBM XT keyboard and some of XT clones need Reset pin to starup its controller. Use pin3 of DIN-5(180-degree) connector for Reset.
Connect Reset pin to pin3 of DIN-5(180-degree) connector. This should not harm keyboards which don't require reset,
it is safe and recommended to have Reset pin on AT/XT converter.
Zenith Z-150 XT and Leading Edge DC-2014 are also known to need this. Reset should not harm keyboards even if they don't require it. It is safe and recommended to have Reset pin on AT/XT converter.
