A2osX is designed to work on any "stock" 128k Apple //e, with no additional hardware. As VBL signal is NOT available as an IRQ on //e (it is on //c & IIgs) it makes preemptive multitasking impossible.

Kernel, loading in Aux LC on top of ProDOS provide API inspired from Linux/Unix World to allow writing applications & command line tools on top of it. This kernel provides an advanced "Memory Manager" able to relocate 65c02 code. "Event Manager" makes TCPIP stack able to listen on several ports, manage ARP,DNS...cache expiration and any background processes. "Task Manager" is responsible to "distribute" CPU time to several loaded processes. "Device Manager" handles event collected from builtin devices as well as devices added by loadable drivers.

Rémy Gibert is working on a new multitasking OS for the 8-bit enhanced
Apple IIe and has made *quite* a lot of progress, and also has developed a
TCP/IP stack within this OS that can do DHCP and DNS resolution. There is
also a screen editor and an assembler. Everything is done in assembly
language.

He has put out a call for assembly language developers. If you have an
enhanced IIe, a IIc, or a IIgs, you can also help by running the system on
your machine (not emulator) and reporting what works and what doesn't.

Download the boot disk here and test it out on real hardware:

He will welcome your feedback about what works and what doesn't work.

I have an army of Apple computers. Perhaps I could help out. I will ping them and see what they need.

Thanks!
