For simplicity and compatibility. The original ELF had no ROM and was started by entering the first instructions manually with switches or (luxury!) a hex keypad. A microcontroller could automate that and keep a ROM out of the memory map. On the original ELF this was only a theoretical luxury, but you had all of your RAM at your disposal at all times. With my modest memory expansion a ROM would be in the way even more because it would reduce the physical address space to map my expanded RAM into.

The microcontroller also has a programmable oscillator and could start the computer with several clock frequencies, including precisely the original clock frequency for the original graphics chip, overclocking up to about 14 MHz and anything inbetween. Even single stepping bus cycles or instructions would be possible. At the flip of a switch you can have the old Elf back again and run the old stuff.
I have lived with several Zen masters - all of them were cats.

His last invention was an evil Lasagna. It didn't kill anyone, and it actually tasted pretty good.
