I've just acquired a Mattel Aquarius 16K ram cartridge but I'm not sure if it's working properly or not. When I type PRINT FRE(0) without the cartridge fitted I get 1724 (bytes - 1.7Kbytes). However, when I type the same command with the cartridge installed I get 11964, which is 11.7K. So does this mean I've only got an extra 10K instead of 16K?! Also, when I run a program to poke a value and then immediately read it from addresses 16384 to 32767, it fails to read the same value before it gets to address 32767 (the top of the memory allocated to the external 16K ram), somewhere in the mid 20000s I think. Any help gratefully received ?

That's awesome Dragonstomper! How much did you want for it, and shipping to the UK?

Hey, I need an Atari 400 keyboard - do you still have it?!

I also need a replacement keyboard for the Atari 400, do you have any left?!
