How to test a Glue chip?
Posted by: smrieck511 on 2025-07-02 16:05:41
What would be the best way to test a glue chip from my sadly battery bombed SE/30 to see if:

A) the corrosion which has been cleaned off was enough to destroy it. Looks OK visually..

B) I didn't kill it with my heat gun trying to remove it.

Thanks for any help. All I have is a multimeter but no oscilloscope.

install it in a known-working se/30 🙂

i'm being pretty serious though. there really isn't many other ways other than testing in-circuit iirc.

If you are doing a Reloaded board, then add sockets for all rare ICs. If it won‘t work, you will easily be able to swap in a known good GLUE if the board is not working…
