Re: Clock Signal: back again for the Mac and UNIX-ishes

Excellent! If you search the forum for 'hsync reset' there is a lot of discussion about the issue, along with empirical and experimentational data. It might reassure you.

Re: ZXpand-Commander

The file length solution is very clever. It would be a lot of work though. A force load would be much easier. I'd have to check the PIC firmware to ensure that there are no special cases for P files.
