I installed NeXTStep onto my 712/80, but it can´t detect my mouse. So I tried several different mice, but none is working.
Which mouse is known for working under NeXTStep?
The 712 can only use PS/2 mice. Any PS/2 mouse should work.
I can assure you, that not all PS/2 mice work! I have tested 3 PS/2 and 2 USB (used with a USB->PS/2 adapter) mice and none of them could be detected by NeXTStep.
Do you have hpux? Perhaps the ps/2 port is bad?
Also possible, but I´ve got no other os to test. Maybe I can test OpenBSD or something like that.
