Compared 0.209 vs current git. Confirmed the change in behaviour.

If you let it do a programming sequence, then quit and start over, the display shows 001, same as the old version.

This new operation may well be correct, but I wasn't able to locate a manual to find out.

Try moving these 3 lines from machine_start to machine_reset

m_digits[0] = s_7seg[(m_addr >> 0) & 0x0f];
m_digits[1] = s_7seg[(m_addr >> 4) & 0x0f];
m_digits[2] = s_7seg[(m_addr >> 8) & 0x0f];

*edit* yeah that was it
