Colour Classic Y1 Crystal replacement? - Battery leak almost madness

Hello everyone! - Long time reader, first time poster :)

On Monday I rescued a Colour Classic that's been sitting on a shelf for a while, and had (surprise, surprise) a battery leak (the previous owner tried to clean it, hence the marks on the board).

In the past two years I've become pretty comfortable with recapping, diagnosing, and fixing boards, but not very good at finding replacements for this kind of specific parts.

My question is: Is it possible to find that Y1 crystal anywhere? For the battery I reckon I can come up with some sort of solution with a MacBatt.

The corrosion damage doesn't look that bad under the microscope, I'll definitely have to fix some traces and give the rest of the board some recapping love, but if the Y1 crystal is hard to come by then I may archive the project for another moment.

And here's another board I managed to fix in the past for reference

Thank you so much in advance for any responses :)

Welcome!

Y1 is a 32.768 kHz radial can crystal, plentiful and extremely cheap on places like Mouser or Digikey. :)

You're welcome! Sounds like you know what you're doing, but I'll drop my two cents anyway: long road ahead for this board.

Probably going to need to replace J4 and J5 and possibly their controllers. U11 looks highly questionable too. F2 probably works but I'd swap it just because aesthetics.

Egret chip and U8 look OK, good news. Suggest you clean IC legs thoroughly, scrape back corrosion. Battery goo turns solder into a hard, resistive, crystalline lump, so I clear and replace anything that looks blackened and dull, with particular attention to IC legs and vias.
