TC5514APL-3 SRAM tester done

My SRAM tester is finally done!

I've finished a project!
This is an important milestone :)
This is probably of more importance to me than anyone else, but I still thought it might be worth writing about, since I've already posted about building this thing...
Now I can test TC5514APL-3 ICs :)
It should also work for uPD444C, M58981P and HM4334P since they're the same thing, but I don't have any of those.

TC5514APL-3 SRAM tester

Ok, this may seem a bit silly...
I recently purchased a tube with 20 pieces of TC5514APL-3 1024x4bit SRAM.
That's 4kbit, or 512 bytes if you will... Access time 300ns.
It's an 18-pin DIP chip.
Why would anybody want an old crappy memory like that?
Well because it's used in some old synthesizers of course!

As far as I know, it's used in the Korg Polysix (that I own) and the Korg MonoPoly.
Probably more machines than that. Or at least it might be possible to use it as replacement for other similar memory chips in other synthesizers.

Aaanyway... How do I make sure they work?
I don't want to open my Polysix, remove my chip, put a socket in its place and use the Polysix as a testbed for them. Also, that's not a fun way to test them.
Now I have an excuse to start yet another project: The TC5514APL-3 tester! :)
