Looking at previous posts, it looks like it's the Gateway Anykey. I'm assuming that this keyboard stores the macro in hardware, which appears to be a difference between it and the current macro keyboards that I'm able to find on Amazon, which seem to indicate that they still require software to be installed on the computer in order for macros to function. I don't know if this is a distinction that matters in practice. The other difference is it seems that all current keyboards that tout macro capability are hideous gaming keyboards that look like they have terrible ergonomics.
