Hi all,

RTM/Z80 is a multitasking kernel, built for Z80 based computers, written in Z80 assembly language, providing its users with an Application Programming Interface (API) accessible from programs written in the C language and the Z80 assembly language.

It is intended to be a simple and easy to use learning tool, for those who want to understand the tips and tricks of the multitasking software systems.

On RC2014, an RTM-Z80 application may be run as a CP/M .COM executable, or may be loaded as a .HEX file under the SCM monitor, or may be stored on EPROM.

RTM-Z80 apps can be executed also on the Udo Munk's Z80SIM.

See https://github.com/Laci1953/RTM-Z80

Very nice, that allows to poke around in a multitasking kernel and study all the inner workings.

Yes, Udo, that's exactly the idea: using the RTM-Z80 manual as a reference, anyone can study the source files to see how the kernel works.

Also, the DEMO folder contains various RTM-Z80 applications, very useful to see how the functions of the system can be used.

I would like to thank Udo once again for the excellent quality of his Z80SIM, which I used extensively while developing my multitasking kernel !

regards,
Ladislau

The September, 1983 BYTE magazine presented a simple cooperative multi-tasking kernel
for the 8080. I Z80-ized it and used in a product I was developing at the time. I currently
use an ARM-based descendant in some of my stuff.
