The Eclipse family took up from where the Nova left off. Whereas the Nova had a very simple and elegant instruction set, the Eclipse extended it to the point of near overkill. Yep, it became "feature rich" and, as a result, the processor is microcoded. An option that was available, which this specimen lacks, was a writable control store which allowed a user to create their own instructions by writing their own microcode.
This machine has a far sexier front panel than the Nova 3 in my collection.
