By the way, the page at
http://cd.textfiles.com/crawlycrypt2/ste/dips_e/readme.txt
differs from http://gfa.atari-users.net/TT030/htm/swi.htm in the
definition of the switch 8 - one says that the switch has to be enabled
for DMA sound, the other says that the switch has to be disabled. Did
somebody ever try this on a real TT?
