====== JP5 ======

^  JP5  ^  SBC V2.1 Boot ROM Select ((SBC V2.0 has two jumpers for ROM select.))  ^
|  1-2  |  normal  |
|  2-3  |  ROM A14 inverted  |

In the normal position, the system boots from the top of the 32K EEPROM

In the inverted position, it boots from code at the top of the lower 16K of the same EEPROM.

This control bit originates from the latch, so it can be changed by writing the latch, regardless of pos
ition.
