Can you please summarize what changes with the new CPLD? Should people who bought the adapter some time ago upgrade?

The latest CPLD version "1321" improves port noise immunity during serial communication, this may help some machines which may have problems using jiffydos when there is noise on the tape drive connector.

This revision was generated because a jiffydos machine could not load well from disk when a specific tape drive (a clone) was attached on tape port, even if an original MOS8501 processor was installed!

Now this behaviour (present also into original CPU) is resolved with CPLD release "1321".

All revisions are working, but if a user find the same combination of [machine that use jiffydos]<>[port noise present, as a specific clone tape unit] can ask to me for a new CPLD with the last revision....

This is a goal of a socketed CPLD: it's easy to swap!
