Advanced BASIC ROM Replacement Mode (OPTIONAL)

*** this functionality is beta currently. It will be fully supported in the near future, stay tuned ***

For users with the do-it-yourself spirit, an optional feature of REX can be enabled.

With a single wire soldered in place, REX permits BASIC ROM replacement!

This means that you can disable the built-in BASIC/TEXT/TELCOM ROM on your motherboard and replace it with a specific block of REX flash memory. Typically, this will be the same BASIC/TEXT/TELCOM ROM image we know and love, with a few changes. So, you can upgrade your Model T with little tweaks like Y2K, the lomem patch, new character sets, put your name on the main menu, etc.
