I've just fired up my second Apple IIe PAL and found Im having strange keyboard probelms. There seems to be a delay when I press a key it then displays the text. Sometime nothing comes out. I press like 4-5 keys and then it starts working. Its very intemidant. I've run XPS diagnostics as this is a non enhanced apple IIe and the RAM, ROMS etc are all good. I've run the onboard diagnostics too and I get the KERNEL OK message.
I've removed all cards too and tried a bare boot and same thing. I've removed and reconnected the keyboard to make sure it's connected properly. I've also swapped out the keyboard rom to make sure its not that.
