I want to post a comment to the Web pages on attached note.
They are well done, but with some errors and only related to 8051 world.
And no EMAIL address to send comments.
I hope that the owner of these pages is "listening" here:
first of all to say TNK's A LOT to him,
second to give him some more info.
HTH  to improve the info on the NET.
Ciao & :-)
