There should be a spring in there - have a look here:

thanks for this! looks like a nice way to fix it - assuming I can find a good spring.
So all there was in there originally was a spring connecting the "flap hook" and some broken anchor point on that rectangular hole?
I thought there was a mechanism to keep the cover up, do I understand correctly that the cover always wants to go up and you are supposed to hold it down while switching disks?

I've repaired a few of my RiscPCs with this issue.

I drill a small pilot hole at the back of the panel (just behind the rectangular cut-out) and use screw-in eyes like this:

The spring needs to be fairly strong and about 1-2cm long when coiled.

It should stay in place when opened if you do the repair properly. It only really springs closed when the cover is near the top.

That looks like it puts the attachment point for the spring a bit high. Alternative method - http://www.jrmiller.demon.co.uk/rpc/mods.html (at the bottom of the page)
I've seen it done with a cable-tie through a hole in a similar place to attach a spring.

To be honest, I've just made a small hole behind the gap and hooked the spring through there but that was the first one that came to hand.

I've used pliers to bend the eye over the rectangular cut-out once it's screwed in place to ensure that the anchor point is roughly where it should be.

Haven't always done this though - it has depended on the size of the spring.
