fuse bits TINY 12 default is "52" as from the factory (use internal 1Mhz RC oscillator)

don't change the high nibble - keep always "5" or 0101 
for the low nibble,use "2" or 0010 for the internal 1Mhz clock (no external crystal needed) eg for CWID.ASM
or for external crystal (eg DTMF.ASM) set the low nibble to "A" or 1100

so low nibble and high nibble is
"52" or 01010010 for CWID - default; don't need to progam fuse bits
"5A" or 01011100 for DTMF - external crystal (no Capacitors needed for 8Mhz)

Always keep the high nibble as "5" or you might get locked out of programming mode

to load the CWID.HEX into the Tiny12 via the sp12v3 DOS LPT port, type
sp12 -iT12 -wpfC CWID.HEX

if the sp12v3 version you get don't include Tiny12, then include the following in the _sp12dev file
