Just had a phone call: Bernd came up with a better and more elegant solution to make our operating system functions ISR-safe: **We need the ability to have a "clear...

@MJoergen and @bernd-ulmann Now that #139 is done, I stumbled over one more thing: In the operating system functions such as `mulu` that we want to make ISR-safe, we need...

For me, user/mode kernel mode is a very big project and not just something we would do just like a small thing. Always think in terms of an overall stable...

P.S. Another solution for V1.7 could also be to make the programmers of ISRs responsible for either not using Monitor functions at all or for exactly knowhing what they are...

## Solution for V1.7 1. We introduce in monitor/sysdef.asm a BLOCK bit in the CSR of the interrupt controller: bit 1. Bit 0 stays the interrupt enable bit. 2. We...

@MJoergen Can you take over this issue and finalize it? The following tasks are left to be done and then this issue can be closed: - [x] Update the documentation...

@MJoergen great observations. Thank you! It is cool that there exists now a test program which can be used to "visually test", if everything works. > So I think we...

@MJoergen One more thought / addition to my comment above: We might want to change to code emitter, so that C uses the monitor functions `mulu` and `muls`, `divu` and...

Cool stuff! There is a challenge: Volker is not using GitHub and his local copy of VBCC must not have dependencies but needs to be stand alone. I think we...

@MJoergen I am currently knee-deep in making MEGA65 work again with all the changes we made in V1.6 :-) (so I am working on issue #69 right now). While doing...
