''[[Face Hugger|A. Stroiczek]]''
== Notes and Differences between v1 and v2 ==
Both versions are doing more or less the same (and are compatible at software side). Both versions produce linear D/A conversion (though in v1 the conversion is glitchy, v2 is more accurate). Also, in v2, the 470 Ohm POT is replaced by a normal 470 Ohm resistor plus 22uF capacitor.
v2 1K 2K 4K 8K 16K 32K 64K 128K
Where v1 uses standard E12-series values. Whilst v2 uses less common values like 2K (which you may not have at home), and even totally non-standard values like 4K (which aren't manufactured, and need to be produced by using two 2K resistors).
== Notes ==
* '''Caution''' Both schematics connect GND to Pin9, which works on the CPC's (unmodified) [[Connector:Printer_port|7bit printer port]], but not on (upgraded) [[8bit Printer Ports]], so better connect GND elsewhere (eg. Pin19).
