If one of the Math PhDs @bernd-ulmann and @MJoergen would like to do me a favor, then you could implement these `SHL32` and `SHR32` stubs in `monitor/math_library.asm` (and maybe even add a test progr…

This is a nasty edge case that is **not** "urgent" in the sense that it is not happening too often in real life: I can only reproduce it from time to time when I **really** stress out the system 😈

Changes to programming model:
The print character at VGA$CHAR will be extended to read/write a full 16-bit value instead of as today an 8-bit value. The lower 8 bits will remain the same as before, i…

As mentioned in our last meeting, adding software emulated floating point is a first step before implementing hardware support. That way we can gauge the speed of the floating point calculations and b…

**IMPORTANT**: As of time of writing, this only works on **branch** `dev-vbcc-vasm-fix`
VBCC supports ISRs: Test the ISR feature and write a timer interrupt/ISR test for VBCC and put it to `c/test_…

The benefit promised by this change will be:
* Increasing CPU clock frequency to 100 MHz and beyond.
* Roughly halving the number of clock cycles per instruction executed.
In total, this rewrite …

I stumbled over the following situation in the context of the refactoring of the timer module to use our new daisy chain module. Consider this situation:
1. The timer fires and therefore requests a…
