Your pics could be a bit sharper, but I read the writing on the TED on 
it as 7360R4A. If you have a working Plus/4 or C16 you could try if it 
still works. :)

About the same as with the C64 and the early VIC-II revisions. From what 
I read the 6567R56 didn't produce a good picture and had different 
timings than the later ones (R8 and up).

It's still the same today, if you get a preproduction model of something 
you're bound to run into problems. If it's a computer or OS, expect 
frequent upgrades and crashes.
