Wow...that was easy :-))
At the step where the technical note says "NEXT, NEXT, NEXT, f1, 4, 0, 0, 0"
then you actually set the start address...you could just press 3FFC....to switch over to enter the data itself...just press "f2" (it actually shows you on the display ;o) and then press twice "F"...then exit with twice "f4", power cycle the bastard et voila...options 01/03/05 are displayed :-))
