difference between funcard 4 and 6

Hi

What is the difference between a funcard 4 and a funcard 6? I ask because I have tried programming a funcard 6, but it does not seem to work. I have beed searching the forums and I can only see funcards 4 being mentioned

Fun 6 is 1024 and Fun 4 is 256, so Fun 6 has 4 times the memory. I've programmed a Fun 6 and it works fine, no difference. Fun 4's are just as good for the job and are cheaper, which is why they are the preffered card...

even fun 2 r enough 2 do the job

thanks guys

There must be something wrong with hex files I am creating. back to the drawing board!
