The flight crew of an HS125 attempted to fly the ruudy SID from teb using a rapid reprogramming of heading and navigation modes in order to comply with the charted heading and fix to fix routing involved. Unfortunately; due to the aged minimalism of their FMS capability; the programming after tasca was incorrect and the jet turned direct to gayel via a heading of 280 degrees after ruudy as charted. Departure control caught the error and corrected their track.

Narrative:
I was the captain flying and departing teb. Our clearance was the RUUDY5 departure gayel transition; etc... I had to manually program our FMS-gnsxls- for wentz @1500 feet; tasca @2000 feet and ruudy intersections; and then the gayel transition. When we departed runway 24 @ teb; I was in heading mode to intercept the 260 degree course to wentz. I switched to navigation to track to wentz and cross @ 1500 feet. Crossing wentz; I switched back to heading mode to track 280 degree to tasca to cross @ 2000 feet. We were cleared to climb to 10;000 feet. The PNF then switched back to navigation (navigation) mode after crossing tasca. Because the FMS had been programmed for the gayel transition; the autopilot turned north to gayel before crossing ruudy because it is a 90 degree turn. We should have been back in heading mode and departed ruudy on a 280 degree heading until vectors to gayel. ATC stated; 'XXX; I don't know where you are going but you should be heading 280 degrees'. We turned to 280 degrees and climbed to 10;000 feet. There was no conflict with other aircraft.after talking to the pilot not flying (PNF) and the other pilots in our flight department; we have decided to not accept this departure (RUUDY5) because of the age of our FMS; the switching of modes 3 times in 8 miles while climbing; cleaning up of the aircraft; running checklist; avoiding traffic; and abiding by the noise abatement procedure for RWY24 at teb.
