Here's a nice starting point for assembly language programming. There's 
an interesting "High Level Assembly" link.

That was the Question... Simulators and Emulators.

Hi all,

to get back on topic, I toyed around a bit and I managed to compile 
emu51 (http://emu51.sourceforge.net/) under GNU/Linux.
This emulator is very early alpha but better than nothing and free 
software, free as in freedom and not as free beer ofcourse.
As it comes as sourcecode + Windoze binary only, I altered the Makefile 
so it now compiles under GNU/Linux as long as you have a working 
installation of the Allegro library.
I've attached the altered Makefile to this posting.

I know this is not a commercial grade emulator but I hope this proves 
useful for hobbyists and students like me who cannot afford commercial 
grade software for 100EUR and more.

HTH,
Matthias

Employer wan to use them, so it is not a waste of time to learn them.  The
architecture is much stranger than the 8052.  But I think the newer 18F
stuff is a bit better.

Provided you have the right fonts installed it runs fine. I have the free
version of uVision 2 on my Linux box right now. I should have included it
in the list.

Tasking tools have been available under Linux for several years. No
simulator though. See http://www.altium.com/tasking/news/pressrel0040.html

So how does the Keil sim run on linux?

No because it is the most widely used, suported and produced MCU on the
planet. There are more 8051's appearing all the time.  Also all 600+
variants will run the same core binary.

ARM yes but not PIC. PIC does not even have a common word size across
the range.

Arm is a good move as it is "the 8051 of the 32 bit market"  but I am
not sure I would bother with PIC. The Philips LPC900 range of 8051 cover
much of their functionality and runs standard 51 binary.

PIC's have different architecture and tools across the range.

AVR is a possibility though.

What does the IDE do? I meant 8051 compilers and simulators.
