A500 Rev3 mysterious timing difference

to all owners of a A500 Rev3 board ...

the following test program gives a different result on a A500 Rev3 board compared to boards with other revisions including A1000

ADF, pictures and source code at
https://github.com/dirkwhoffmann/vAm...inttim/timcpu2

discussion at
https://github.com/dirkwhoffmann/vAmiga/issues/711

the main question is "do all Rev3 Boards exhibit this difference?"

In case you have access to a A500 Rev3 board, could you please run the test and help to shed some light on whether this is a systematic difference of board revision3 or if its just a single machine which has an electric flaw ? Thank you very much in advanceā€¦
