IBM PS2 mod. 30. Keyboard feels sluggish. Alley Cat feels sluggish.

I might be remembering it wrong, but on my recently acquired IBM PS2 Model 30 (386sx NOW! upgrade) the keyboard feels a bit sluggish. Have only tried couple of games, but I remember clearly how Alley Cat used to run on my long gone Model 50. The keyboard doesn't register that well, when holding down the buttons. There is some kind of delay, and the repeat feels to slow.

The framerate feels ok, and a Kingston benchmark program register the computer running at 28 MhZ with the 386sx upgrade (which it should and it is normal)

PS/2s tend to default to "slow" keyboard repeat/input unless configured as "fast" via the RefDisk. Unfortunately I can't say if this is so for the Model 30, as that's one I've eschewed.

Most of what "we" know is here:

Yeah, I did change it to fast. And later found out, that other games run fine. It's just something wrong with Alley Cat. When I hold UP or DOWN button, sometimes it just skips a lot of presses. Example (for you Alley Cat fans), I cannot even reach the bottom of the fish bowl in the game, before drowning. The cat just slows down a lot... then speeds up... the slows down again. Weird.

Anyway. Just glad that I got the machine running again.

That's not normal, and it might actually be something wrong with your keyboard (dirty contacts), not the system.

Agreed, sounds more like intermittent contact than a straight clocking issue.

I tried with another PS2 keyboard. Same thing. So it's something else. I´m guessing my 386sx NOW upgrade is doing some weird keyboard stuff.
