v0.6 just posted on https://github.com/UKTailwind/FUZIX/releases/tag/pc3-v0.6

This has major internal changes and validates against all the test programs I have used so far. Performance is increased by about 15% for C and MMBasic. Manual is updated. Remember this is Unix V7 so for anything Unix that isn't in the manual just look up V7 documentation.

Many of the programs in the VGA demos thread will now run if they rely on PIXEL and or LINE drawing - try them

I've just got V0.5 running, which has graphics, so I compiled versions of Mandebrot and a recursive Mandelbrot. at the same clock speed I got.
Mandelbrot in MMBasic 15.22 seconds compiled on Fuzix 2.01 seconds
Recursive Mandelbrot in MMBasic 14.04 seconds compiled on Fuzix 2.96 seconds.
Oh bugger in the time I was writing Peter updated it, I'll try again

v0.6
Mandelbrot 1.74 sec.
Mandelbrot recursive 2.58 sec.

To power off, type shutdown (or at minimum sync, then wait a moment). After an unclean power-off
the next boot repairs the filesystem automatically (fsck -a -y).

Would this be something of a concern for an embedded system?

Yes. You need supply failure detection and something to hold up the supply for long enough to shut down. You *can* rely on fsck -a -y to clean things up on boot but it's not good practice really as it delays the boot sequence - sometimes by a lot because it's a full filesystem check.

A-ha. I use a 5V UPS anyway and so I would detect that the machine power is lost and the system can be instructed to shut down in an orderly fashion  

When I try to run BBCBasic, I get



It used to run under 0.4
