"So I'm not sure what makes something a "microkernel""
"Micro" would imply size, but I'm sure that (alone) isn't the defining factor. However, from memory, RISC OS's ROM (or EEPROM?) was 1 MB, the same size as the 1 MB (in my machine, and I also recall half available) RAM (the framebuffer could easily take half alone..). Both the RAM and ROM are tiny by today's standards.. with everything in that 1 MB ROM: the "kernel" (if you will, that term (or userspace) was never used in my memory, but supervisor mode was, and (and [F]IRQ)), windowing system, outline font system (first in any OS), WIMP (with graphics routines, such as flood fill, ellipses etc.), C library (that could be replaced with a RAM version, like all modules), 8-channel software (and volume control also in software, as logarithmic) time multiplexed sound to one channel, fast functional/Pascal-inspired (or had PROC, not just GOSUB..) BBC BASIC (with included ARM assembler..) interpreter, software sprite support (plus separate handling for the one hardware three color + transparent one used for the pointer), filesystem (including support for additional pluggable ones, such as were implemented for read-only ZIP file support), networksupport (their oven Econet), etc.
While cooperative, but with MMU for protection between tasks, I recall no interprocess communication (that I think is the key to microkernel).
I think we are at least on the same page, thanks for the revert, I saw the deleted stuff, including interesting company info.. :) comp.arch (talk) 19:04, 13 January 2016 (UTC)
