For the Trinity, space in the ROM would only have to be found to fit in a very small routine to see if the Trinity is connected and then if it is load an extra chunk of code from the onboard 128K EEPROM into memory. It would then execute what it fetched from the EEPROM to load the full DOS into memory. Although, why not then just go the whole way and store the DOS in the 128K EEPROM to save having to fetch that from the SD card. >From what I remember back when I was changing ROM3 for the Mayhem - removing the copyright message and coloured bars would possibly be all that's required to get enough room for the tiny chunk of code to fetch stuff from the EEPROM.
