Made an offer to someone for the handheld version... he wanted too much, so I skipped out on it. Next day, I see the auction for the full machine one, mentioned in this thread from almost three years ago. Made an offer on that one, and then I see the original mention in this thread. Guy accepted the offer, so it would be rude to back out.

I figure this way, Rik doesn't need to sacrifice his for dumping needs, if dumping it requires destructive methods. Would Sean still be the person to send this to? Or someone else? Would also need the backdrop scanned, and the front face of the machine scanned.
Rik sold his handheld collection a while ago.
uCOM-75 isn't dumped by anyone yet, and AFAIK hasn't been decapped before either. So it's unknown if the bits will be visible, and rom row/col layout is unknown.

I bought a couple of upd7508s a few months ago since that one is used in the IXO TC101. I just bought a upd7502 and decapped it. I can't see the bits on either of the dies. I haven't tried removing the top metal layer on either chip yet, but on all the other NEC chips I've decapped, I've been able to see the bits with it in place. I'll try to get these cleaned up, take pics, then remove the top metal layer and see if the bits are visible.
