[HELP/REQUEST] bq20z90 Legacy Software (bqEVSW) or .bqz file for bqStudio

Hello everyone,
I'm a technician currently servicing a medical battery for a Mindray monitor that uses the bq20z90 chip. I'm using the EV2400 interface, but I've run into a dead end: the official TI links (SLUC080 / SLUC141) are down and I can't find the legacy bqEVSW or the .bqz configuration file for bqStudio.
​If anyone has these files archived or could share a working link to the software, it would be a huge help for my medical equipment repair shop. I've already checked the standard TI repositories with no luck.
​Thank you very much in advance for your time and assistance!

 NLBA1 software supports this chip. 

 Unseal, Clear Permanent Failure Flags, Read and Write eeproms. Also parameters could be edited in the integrated Eeprom editor.

@tracker135n9 Is this software compatible with the EV2400 programmer?

Our software is compatible with the EV2400 programmer; however, certain functions—such as charging, discharging, and calibration—are currently not operational.
