Hello, just a correction to myself: I myself wrote: > SEI/CLI is not more readable, it is also more reliable! "SEI/CLI is not *only* more readable, ..." Another idea: Why not provide little IRQ and NMI handlers that don't do anything but mapping the I/O in, executing the original interrupt handler (with PHP/JSR, of course), after returning from that one restoring the port 1 and doing the RTI? This way, one would not loose one IRQ/NMI on the most portable and reliable way. This is something I always wanted to tell the people who just poke the CIA 1 to disable the IRQ.
