At double waveform frequency, the output changes at double speed; there are no irregularities. The cycles of the waveforms were 512 bytes, unless I remember wrong. This information is for the 6581; I haven't tested the new SID. So, there's no need to have a REU to measure the waveforms. Marko - This message was sent through the cbm-hackers mailing list.
