Hey Folks,
I've been reloading some more SE30 boards and have finally come across a board with some bad chips. I'm on the hunt for a UH7 replacement and found the files to program a replacment using a GAL16V8. Just wondering if anyone has tried programming with this chip from digikey:

https://www.digikey.ca/en/products/detail/rochester-electronics-llc/GAL16V8A-15LVI/12133900

I tried UT source but they don't appear to have these in stock atm.

I'm also on the hunt for a Sony 3430045A (UB10/11) but I don't think there is an alternative to this chip. Found some on UTSource but of course it's 8 dollars in chips 30 in shipping. So if anyone knows of an alternative I would appreciate it :)

Thanks

DosFox on the TD discord reverse engineered the SND chip, check there, the schematics and gerbers may be open source.
