This is not just a programmer, but a dev. card - but it may 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")

Cheers,
FoxyRick

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.
