I thought that's what " having same 8051 core" is all about. so, do
they all have different assembler instructions? and even if I create
small app which uses only 1 I/O port and timer - I'll not be able to
move it to another mcu without a lot of changes?


No they all have the same 'core' with variations in additional bits. The
other posters misunderstood, they did not realise the AT89S... is just
another 8051 MCU.

You keep going with assembler. It will give you an excellent grounding in
the nuts and bolts of embedded systems. IMHO it is essential to understand
this first before using any HLL.
