Swapping EC030 processor with a 030 processor

If it's a PGA type: yes.

I only know of the A3630 with a QFP '030 but there may be others. (Of course QFPs can be changed as well, but it'd be a pain to un- and resolder plus making it difficult to find a replacement.) You'll probably want to make sure the '030 is socketed, too...
