Narrative:

Due to poor visibility and bad weather [at destination] we departed approximately 1 hour late. After takeoff from runway; we were assigned right turn 110; climb to 3;000. Before reaching 250 knots or 110 heading; and before 3;000 altitude (approximately 2;700 feet) we got a triple chime; overspeed clacker continuously (until just prior to touchdown) and lost the captain's airspeed; altitude; aoa; and vertical speed. We also lost auto cabin pressurization; and the heading presenter showed dashes and the altitude pre-selector showed 9999. We elected to return to [departure airport] because we were in VMC and under landing weight and we could still see the field. We transferred controls to the copilot's side because all those readings were still accurate. Once we swapped the autopilot from left to right; the heading preselect and the altitude pre-selector came back. The captain's side remained red X's and never returned. We completed a normal landing without issue.
