It is basically an 8088 interpreter, with simulation of the floppy disk, clock
and display (partially).  There is no input.  It interprets a raw 8088, and
knows nothing about DOS or even the BIOS.  It can run MINIX, but it is slow.

The full source is included.

Only with a lot of work.  The tape contains no binaries and does not contain
any C compiler (neither source nor binary).  This means that you need the C
compiler at the very least.  Then you have to figure out what to do.
Since all the sources are there, in theory it should be possible.

There is only one distribution so far, MINIX 1.1.  Someday there may be a 
MINIX 1.2, but not until the Fall, at the earliest.. 

>Can anyone remind me on how to get the compiler sources!
See the preface of the book.  Briefly, they are available from UniPress in
Edison NJ at (201) 985-8000 and Transmediair Utrecht BV in Holland at
(30) 78 18 20.

>Does anyone know if the separation of as and ld has been completed and if
>the new versions will be in the new, updated distribution?
I know.  It hasn't happened yet and won't for months, at best.  The split
I & D asld is almost ready, however.
