SUB WriteReg (Reg%, Value%)
'  Purpose:   Writes to any of the SB/AdLib's registers
'  Variables: Reg%: Register number,
'             Value%: Value to insert in register
'              (Note: The registers are from 00-F5 (hex))
OUT &H388, Reg     '388h = address/status port, 389h = data port
  FOR x = 0 TO 5   ' This tells the SB what register we want to write to
    A = INP(&H388) ' After we write to the address port we must wait 3.3ms
  NEXT x

That program will produce a motorcycle engine effect.  I do have code
that will play a frequency (from 0 to 800 I believe) on any of 11

By the way, we've had quite a few people with names that have been tough

give me a hint?  It looks like Zem-ij-ew-sky - am I close?
