hi all

first thank u too much FoxyRick for your help

i just wanna ask a question is this kit valid for all types of mc68hc11

because i see on it a name 68hc11a1 and i am new for motorolla and i donnot know is that a different type or what

thanks too much for your help
 

Hi again,

The HC11's were made with on-chip ROM, programmable during manufacture. The A1 varient has this ROM disabled, so an external EPROM can be used. Check out the following document for more information (the "pink book")

Hi,

Don't worry, I don't mind you asking.

I don't know the answer though. I suggest you email the dev. board site and ask - they should know.

Sorry I can't help more,

FoxyRick.
