Perhaps you should try some spelling variations:
developing microcomputer » developing computer, developing microsoft, modelling microcomputers
microcomputer https » microcomputers http, microcomputers gtt, microcomputer books
activation streams » reactivation stress, activation state, activation states
activation steps » activation sets, activation systems, activation states

You may be able to get more results by adjusting your search query.

• The words AND, OR and NOT may confuse the search; try adding quotes: "processing ((activation steps) OR (activation streams)) developing microcomputer https~".
• Adding a wildcard symbol may retrieve word variants: processing ((activation steps) OR (activation streams)) developing microcomputer https*.
