Press HOLD/Next HOLD - check inbound track and turn direction is correct (eg 272/L) - engage L NAV - sip coffee - watch in wonder - try to remember when you could track NDBs and do NDB holding patterns on a DG and fixed card ADF - shudder - sip coffee
Forget about the hold exit time you were given - depart hold 60-90 seconds late - receive feeder fix time from ATC - complain to ATC that now you have to speed up to meet that time
Ah good times.
