C128D - 1571 drive compatibility with demos
Hi,
I just got a commodore 128D, with built in 1571 drive. As far as I read this drive should emulate the 1541 in c64 mode, but... I experienced a few crashes running certain demos. So far Deus Ex Machina and Insomnia both crash right after turning disk side. Risen from Oblivion V2 runs fine in C128 mode.
I thought about a not 100% correct emulation of the 1541 in c64 mode.
Has anybody had the same problem?
thanks,
Ready. |

The 1571 in the C128D(CR) is a bit odd and a bitch when it comes to compatibility. People are aware of that, but keeping stuff compatible is a little tricky. |

Has anybody tried to mount a switch to disable it and work with an external 1541 set as drive 8? Somewhere I read it is possible, but there was no feedback about it.

Putting a switch on the 1571DCR's ATN line should do the trick.

Works here too. Drive misaligned? |

Hi,
I think it might be that I touched the head stop adjustment by mistake. I released the screw that holds the stop mechanism on the step motor shaft. Is there any chance to re-tune it? The drive reads, but with some difficulties.

Uhm drive alignment is quite some trouble. It requires an Oscilloscope or some other suitable measurement device and an alignment disk. |

yeah, I guess that the "turn the screw until it works again" is the cheapest and most reliable method. But before that I'd like to have a look at the canonical procedure on how to do it. I tried to google for it but I haven't found any good instruction. Does anybody have such a thing, please?
thanks,
