Air carrier First Officer reported multiple system failures during climb. Flight crew referenced applicable QRH items and diverted.

Narrative

Passing through FL290 the captains PFD (Primary Flight Display) suffered a malfunction which caused an uncommanded disengagement of the autopilot. We established control of the aircraft and assessed the issue. We came to the conclusion that the captains PFD had failed so we accomplished the associated QRH items. Shorty after regaining our auto flight capabilities on backup systems; we were informed via atc that our mode C altitude reporting had failed which we then rectified that second issue. Soon after this issue occurred we received another master caution indicating a pack had failed. Associated QRH items were completed. At this time we had already discussed that we were possibly no longer rvsm capable and may have to descend and if we were to do so then we may not have the fuel to continue safely to our intended destination. The captain then gave me the controls since my PFD; autopilot; and all other instruments were the only operable ones while he looked up our rvsm equipment requirements. At this time we got another master caution showing that the speed trim fail and Mach trim fail lights were now illuminated on the overhead panel. The captain ran the associated QRH items. We requested a descent to a lower altitude out of rvsm airspace. The captain then got in contact with dispatch about a possible diversion. After discussing with dispatch we elected that a diversion to ZZZ was not only along our route of flight but an obvious choice for a diversion. Cause: These were known repeat writeups and should have been dealt with at the time of finding.
