Hi;
I had a look at the Museum pages and I did not find the page were the differences are pointed-out. Externally you just have a different (some think it's a worst) key feeling in the newer halfnuts, and their LCD has rounded corners instead of the sharp-edged ones found in the fullnuts (earlier). Internaly the HW was reduced such the halfnuts do not have an extra mainboard as the earlier fullnuts, and you will find one PQPF-type mainprocessor directly soldered in the keyboard (inner face). RAM/ROM/Display drier are built in the LCD assy, and for the CX, and extra PCB will hold time and X-functions chips.
Despite these external and internal differences, both types are fully compatible with eachother.
Cheers.
