I acquired this Motorola 68xx ASM source code quite some time ago
but for those people that want to get down and dirty and do your
own Megasquirt computer EFI it might come in handy some day.
The ASM Megasquirt source code is also available and attached.

IMHO The problem with software is the bugs are proportional to
the number of instructions cubed. Also the higher the level
of the programming language the more the possibilities for bugs.
For example C verses assembler language. There are potentially more bugs
in the C compiler than there are in the assembler.

Another problem with the high level languages like C is you never know exactly
how long it will take to execute a section of code. That is absolutely
essential when you are programming real time devices like EFI.  For this reason
alone I recommend assembler.

BTW many people have been killed by computers flying Airbuses :)
