I recently acquired a Sega ST, She is like new, but the prior owner let her sit ...with batteries installed. There is minor acid damage to the memory chip area. I tried to install a new socket and NVRAM, but it didn't work. My soldering looked fine to my untrained eyes, but non op now. (She was mostly working before.)
I want to send the board out to be fixed and tested. Close to Columbus Ohio would be best, but flexible.
RECOMMENDATIONS?
