DivIDE JUMPERS
DivIDE interface contain two jumpers. - Left jumper is on board signed as "E" or "JP2"(on old PCB versions) and is used for enable divide memory+write enable to EEPROM (for reflash system). Onwards 2007 is in DivIDE interfaces use new R GAL chip signed as R"GAL. This versions support also new allram mode 16kB paging (if jumper E is open) !!! - Right jumper is signed on board as "A" and is used for ZX128+2A/+3 computers only.  |

| JUMPERS INFO |
Jumper E (JP2) must be closed: - for enable DivIDE memory automapper - for write protection EEPROM memory - for disable allram mode ( * ) |
Jumper E (JP2) must be open: - if you reflash EEPROM - if DivIDE memory must be disabled (only IDE ports can be used) - in 16kB allram mode ( * ) |
Jumper A must be closed: - if DivIDE is connect to ZX128+2A or +3 models |
Jumper A must be open: - if DivIDE is connect to ZX models ZX16/48/128/+2(grey) |
( * ) - This features is available
only on DivIDE interface with new R"GAL chip. DivIDE with this GAL is
possible buy at DIVIDE
SHOP. Old DivIDE interface can be also upgraded if you replace R-GAL
chip with new R"GAL (possible buy in same shop)
