Sprinter AY-3-8910/12 hard emulator

The 3rd version of the AY emulator on Sprinter is coming out.
Regarding what was there, an envelope generator has been added, the ability
reading from AY ports, the noise generator has been improved.
Plus, in the firmware with AY there is an expansion to 512 Pentagon.

The differences from the real AY at the moment are as follows:
1. The amplitude regulator is linear, not logarithmic.
2. Tone generators use the full 16 bits of master registers as a period.
3. The noise generator uses the full 8 bits of the master register as a period.

Points 2 and 3 are not for bravado (I consider this a drawback and a source of glitches when running one music program). They are a consequence of the new coprocessor architecture, using an 8-bit nanoprocessor.
Point 1 will be corrected as soon as I “shrink” the circuit.

Wow! The Protoss are attacking my Zerlings! It's time to get going. Ivan... data-saferedirecturl="https://www.google.com/url?hl=ru&q=http://www.atlant.ru/peters&source=gmail&ust=1785433335124000&usg=AOvVaw0TWA_Agc1YtL2WAF76PBEw">www.atlant.ru/peters *
