Citizens of Vogonosphere.. I've got a tough one.
While recently testing whether a recently aquired 486/DX4-100 was a good working CPU or not, I noticed my Serial-version classic Microsoft "J" mouse wasn't working in any DOS mouse-enabled program.
I thought it might be due to the new CPU, so I tried my mouse with a known good DX4-100... same thing. Then I tried it with an AMD X5-133... Same thing... mouse no workie. *However*, when I popped my i486/DX2-66 in (the CPU I usually keep in that Mobo) everything is honkie-dorie.
I haven't tried other CPU's yet, but at this point I'm puzzled. The motherboard is an FIC PIO-3. The only correllation between the CPU's is that the ones that appeared to cause the mouse not to work are 3.x volt CPU's while the DX2-66 is a 5volt CPU.
Any ideas? Similar experiences?
