  • Commodore 64 and 128
  • MS-DOS on whitebox x86 hardware

At random:

  • Domain/OS on Apollo workstations
  • HP/UX on HP 9000 workstations

There may be (read: probably are) a few other things I forgot at the time I was writing this page, so if you're looking for a Dan Birchall who has done something entirely different in technology, it may or may not be me.  Please contact me to be sure one way or the other.
