Trilogy & Vision Factory Copyparty 1989 was held in S-Hertogenbosch, The Netherlands. Trilogy's co-arrangers were originally to have been Quiver (which soon after disbanded), then BTW (which also disbanded), before finally Vision Factory became their partners. Police visited the party and shut down the phone lines, as well as the bar that was running without a proper permit.

First mentioned in the Cracker Journal 13 (march 1989) news section, "Trilogy & Vision Factory & BTW (?) on 1st April".

Party reports followed in Business #3 (1989), Cracker Journal 14 (may 1989) and P.E.N.I.S #2 (may 1989).
