I always wanted a Memotech back in the day, but never saw one anywhere except Your Computer magazine!<br /><br />I'm also having big issues with T80 - to the point where I'm going back to using a real Z80. the issues I've had were related to timing, and the way t80 seems to handle interrupts differently. <br /><br />Sorry I probably can't be much help :/SJBhttps://www.blogger.com/profile/01893701778281575461noreply@blogger.comtag:blogger.com,1999:blog-7607885452172131382.post-39227748250912974882012-02-03T09:09:56.195-08:002012-02-03T09:09:56.195-08:00Hi.

As it seems not to work like a true Z80A!<br /><br />I wondered if it was possible to ‘pick’ your large Brain and get some hints on what may be the problem ??<br /><br />Any guidance and help would be much appreciated.<br /><br />My Website is :<br /><br />One Chip Memotech MTX512 Computer<br />sites.google.com/site/onechipmemotechmtx512computer/<br /><br />Andy Key's site<br /><br />Andys Memotech site - Links ReMEMOTECH<br />www.nyangau.org/memotech/links.htm<br /><br /><br /><br />Kind Regards<br /><br />LezLez Andersonhttps://www.blogger.com/profile/01656405533836958175noreply@blogger.com
