Below is a draft of a possible sensible formal request we could make to Philips with regard to bootloader enhancement. It is simple and practical. If Philips agrees we can use interrupts by copying interrupt instructions and constant addresses to the start of RAM and setting MEMMAP to RAM mode. We can still use IAP features of the bootloader. There is no sense in replacing the boot...
