Thank you very much Wouter, but I can not use 1K for
the bootloader.

I have made one for a customer, but it uses a very peculiar protocol,
because it is meant for a string of 10's of chips, with 74HC04's as line
drivers, using a pulse width encoding so timing is not critical (uses
internal oscillator). And it is (of course) written in Jal, and it takes
1k code. If you are interested I could ask my client - he is often very
generous in contributing to the open source idea.
