Clear UV roms

Nope, those 27c010/020 are only 8 bit chips.
You need a pair of 27c200 (128k*16 bit) for the A1200.

27c400's can be used too.. either as a 1MB ROM, or just burn the image into it twice and use as a 512KB ROM.

It's times like this I really wish I could mention a project by another Amiga.org member :sealed:
(unsubtle hint: pin compatible and a lot easier that faffing about with UV erasing ;-) )
Hopefully it won't be long before there's some news.

This way, the 4 kickstarts would have there code staggered every fourth memory location (With a address pin dispalacement of 2).

I'd do it the other way around, Amiga A2->ROM A0 , and use the top 2 address lines to switch between kickstarts. That way, you just have to join all the different images together instead of having to interleave them (plus if you use flash instead of EPROM you can replace a single ROM image without having to rewrite the entire chip)
