So this is for apple. I have a 512k and I need to replace the CRT. How hard is this or should I just buy another 512k to use. Noted I have a parts one that I use for this one and the CRT is in there and a 128k would be useless to harvest when I'm about ship it off. I also need a new housing as mine fell apart the other day so I might buy a new one and swap stuff. Sent from my iBook G3 Snow that fell apart.
