I've been checking the connections detailed in the schematic and also in the reference manual of PS2 PMOD:

https://reference.digilentinc.com/_media/reference/pmod/pmodps2/pmodps2_rm.pdf
Is it correct the numbers of pins 5, 6, 8 on J1 PS2 connector?
In other references I found that they are numbered 4, 5, 6 respectively.
