Portal "Want You Gone" on Old Computers

This is my halfhearted attempt at creating the portal 2 ending on ancient computers. Please don’t bother commenting on how one of them is out of sync and how it sucks. I already know that. Computers in this video are: IBM PC-XT - 1983 Compaq Portable - 1984 Compaq SLT-386 - 1989 Compaq LTE Elite 4/75CX - 1994 The program used to create this was Microsoft qbasic for ms-dos. The computers were manually synced.
