Default Re: Yet another MK14 tape interface (ESP32).

So is it better to leave the fast uploader scratch variables at 0FF8-0FFA or move them down into the 'system variables' area 0F00-0F11?

In all cases the use of either area - 0F00-0F11 or 0FF8 - 0FFF for user code carries with it the certainty of corruption of some of the bytes in those areas on return to the monitor - even if the program auto-runs, if the user resets the computer for any reason the monitor will corrupt those areas and it will not be possible to manually re-run the program, it will have to be reloaded and autorun again.

This is just a known hazard of placing user code in either area.
