The thing seems a little rusty anyway so I guess the advice is to sack it

Yes, my advice remains the same, don't risk it, buy a new one.

For interest only, did you try operating it while it was broken? (i.e. when one of the two latch prongs was missing)

No! What happened after I snapped the top one was I closed the door and it went on with no programming, on its own and I hit the power fast!

Ok, I just wondered if you'd tried switching it on... the safety system should have what amounts to a self-destruct if certain dangerous conditions exist - for example if the door was forced open.  This would mean if you tried using it with one of the latch prongs missing then it would stop, and wouldn't operate again until it had been professionally repaired.

That the microwave started when you closed the damaged door might suggest there is something fundamentally wrong, because that shouldn't happen.
