thanks michael,
i've looked at the cygnal developers kit.
it's not excatly what i'm looking for now.

it's a good idea to step over to ISP, i searched for some flash uC's of philips.
and i found the 89C51Rxx uC's.
this one looks fine to me. and i want to use this one.

now i want to know what i need to program ISP.
i also read the tutorial about flash programming, but i still can't figure out what i need.

i think i need an ISP programmer and ISP software (flasgmagic??). do i need more, or are these things unnecessary?? and how do i connect this to my uC??

and what is the best ISP programmer, is the epsilon5 MKII from equinox good enough. i don't mind to spend some money for these things. what do you suggest??

thanks in advance,
Hans
