 I have a VP280.
When I test SN74191 comes a false "wrong piece".
Testing the same device, but selecting 74190, gives "OK"!!!

How I can fix it?
Or is a new Software for download?
I am using the first (original) Software.

Thanks.
Jean.

 74190 and 74191 are synchronous，reversible up/down counters.74190 is BCD counter. 74191 is 4 bit binary counter.
