Looking for a UH7 and UB10 replacement for Mac SE30

[ComputerCompulsive]

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:

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

Use ATF16V8 instead

I had an extra SE 800k that I took a 3430045A off of... they only have one of course since they're not stereo but it's there in case you have an extra SE board by chance.

One like this?

Assuming this is also compatible with an XGecu T48 programmer.

Could do for now, would still want replacements longer term but this would let me get the board sound sorted at least.

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