help with VIA test prog needed

[nbla000]

About my original curiosity about locations $9116 and $9117, I've tested 3 different unexpanded PAL Vic-20 and results are all different.

My tests was, PEEK 37142 and 37143, Power OFF/ON, PEEK, Power OFF/ON, PEEK

VIC1:
PRINTPEEK(37142) = 255,255,255
PRINTPEEK(37143) = 255,255,255

VIC2:
PRINTPEEK(37142) = 171,175,191
PRINTPEEK(37143) = 191,255,191

VIC3:
PRINTPEEK(37142) = 91,195, 91
PRINTPEEK(37143) = 245, 81, 91

I don't know if results are normal, in any case the only certainty is that after a Power ON, reset does not change values on $9116/$9117 as expected.
