Re: A83: Shells on the 83+
You don't need a multi-tasking kernel to implement a crash protection.
You can do it with a mere interrupt routine, like I did in Zac and Ion86.
Btw, writing such a multitasking kernel is definately possible on TI calcs,
since I wrote one for the Ti-86. The main problem is screen sharing,
because if you want to allocate a full screen to each task, it will take
lots
of memory (not really a problem with the 16k free page on the Ti-86).
