I also think someone has attempted a conversion job on this machine. Some thins that you could try: - There is a frequency adjustment near the clock crystal that can be used to tune the color frequency. Adjusting this can bring the color back. - Is the 1084 monitor configured correctly? If the composite video out of the C64 is used, the 1084 has to be set to CVBS video with a switch. If it is set to LCA, it is possible that it will only display b/w. The picture quality would be better if a video cable with split luminance/chrominance signal is used, and the 1084 set to LCA video. - As Nick said, the modulator type is to be checked. Using the NTSC modulator with a PAL video chip can lead to strange results. The DIN video output will be fine, though. - the slow startup is not a problem: Old versions of the 64 took longer than new versions, this is a change in the Reset timing circuit around the NE556 (which is not there in new versions anyway, I think). You might be used to a newer version. To Nick: A whole batch of "Aldi" 64s were 'made in USA', with a production date of 1987 and the small version E board inside. They all were sold in Germany and of course they were PAL machines.
