A message to my little brother who grew up playing Bats on one of these computers in the late 70's.<br /><br />The Hewlett Packard 85 used a capstan in the disk drive to move the DC100 tape wheel forward and backward. The original rubber used on the HP-85 computer capstan becomes gooey and soft after 30+ years.<br />I just got this HP-85 running.<br /><br />This link below describes how I fixed the gooey wheel<br /><br /><a href="http://web.archive.org/web/20121221033234/http" target="_blank" rel="nofollow">http://web.archive.org/web/20121221033234/http</a>://www.ideawindow.com/hp-85.html<br /><br /><br /><br />#hp-85 #hewlett-packard #gooeywheel<br />...<br /><a href="https://www.youtube.com/watch?v=EI3OFOaS3Dg" target="_blank" rel="nofollow">https://www.youtube.com/watch?v=EI3OFOaS3Dg</a>
