At the moment the kludge already supports what I most want to do with it: test my own software. The transfer speed increased due to some final touches all the way from 5 kcps to 8 kcps, mostly because of using <em>phi2s<\/em> instead of <em>phi2<\/em> for sync. Surely there&#8217;s room for improvement \u2013 next I&#8217;ll probably try halting the CPU when updating the latch \u2013 but as the speed is already more than 30x compared to the cassette port, there shouldn&#8217;t be too much to complain about.
