The old school way.

I have access to a EEPROM programmer for anyone in need :-)

For upgrading an Astro Spectra Plus, you'll need to connect thru the mic port... with an unobtainable connector. d-sub pins, shrink wrap, and hot glue were used once with success.

Better method -- 3d-printed connector
