Apparemment il y a des différences quand même :

But under the hood, the Mk II series had several improvements. The VCO design was improved for better tracking. The power supply was improved. The sample+hold memory was improved. The keyboard current source was improved allowing for CV and Gate control to be added. The rotary pitch bend knob was also replaced by ARP's own PPC (Proportional Pitch Controller) - three pressure sensitive buttons, either by factory modification kit on earlier models, or from the factory on later models.
But the biggest change in the Mk II was in its filter. Early versions of the 2810 model still had the 2-pole model 4023 filter used in the Mk I but were soon replaced with a beefier 4-pole VCF (model 4035). This filter used a ladder design that was very similar to the Moog filter.
