Re: Clock Signal: back again for the Mac and UNIX-ishes
Welcome back Thommy! I've actually been keeping an eye on your most impressive work for a long while now. I'm often found over at *. and seeing as I like my emulators minimal and potentially seizure-inducing - well there was only one choice really. As a Mac owner I've built from source a few times a...

Re: Problem with my new ZXpand+
Please start a new topic in Development to discuss the serial transfer. That way the information will be easier to find for others wanting the same thing.
