Jut looked up MOS (later CSG) and I think they were stuck on some pretty old technology... My guess is that the Amiga chips are probably even 3000nm (3micron)...


Wasn't some parts of AGA fabbed by HP? Presumably because CSG couldn't fab what was required.

Anyone decapped an OCS chipset to see the die sizes and get some sexy images online?

Wikipedia says that an 8500 transistor chip (Z80) on 4um was 18mm^2 (just over 4mm by 4mm. The 8086 was a 3um chip and had 29,000 transistors on a slightly larger die. The 68000 was a 4um chip, but it looks like it had denser logic than the Z80, partially offsetting the extra transistor count (or it doesn't contain 68000 transistors).
