Repairing dead 800xl spacebar

Recommended Posts

Hi all,

 

I have successfully repaired the motherboard on my 800xl to the point where it will boot to the ready prompt.  I am in the process of putting the machine back together and realized the space bar is always in the depressed position.  If I flip it upside down or lift the keycap it comes up, but gravity pulls it back down to a fully depressed position when I let go.  The keyboard mechanism was made by Mitsumi, if that matters.  What are my options for fixing this?  I'm not seeing an easy way to remove the spacebar.  Thanks in advance for any help.

First of all... is it a mylar based keyboard, or a keyswitch (ie alps) type keyboard where each keyswitch is soldered to a pcb?

 

Usually the spacebar can pop off if pried upwards carefully and evenly, with metal bracket that keeps it balanced...
