[sdiy] DAC Emulation

[MTG]

I find this odd:

http://www.alyjameslab.blogspot.com/

"The VLINN use DAC AM6070 emulation to decode the EPROMS content in real 
time, a specialized DAC back in the days that was able to encode/decode 
µ-Law companded data. A form of compression enabling a 12bit range out 
of 8bit storage."

I mean, this conversion can be done mathematically quite easily or even 
using a look-up table. I wouldn't exactly call that "emulation".
