	Happy New Year 2016!
	Did you know ... that back in 1885, Wikipedia editors wrote Good Articles with axes, hammers and chisels? Thank you for your contributions to this encyclopedia using 21st century technology. I hope you don't get any unneccessary blisters. – Cullen³²⁸ Let's discuss it 06:49, 31 December 2015 (UTC)

"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)
