RAM chip source

Hi all.
This is just a quick post regarding a source of 41256AP-12 ram chips.
I recently bought 50 of these: https://www.utsource.net/sch/KM41256AP-12
Last night I upgraded one of my STFM mainboards, a C070789-001 REV .F to 1MB on board RAM using these, and it all went great, so I thought I'd let everybody know that it seems to be a good source.
I ran it for some time with Yaart (Attached to this post) to test, and had no issues. I'll be upgrading a C070789-001 REV .D soon, so will post how that goes.
If you're doing this, then you'll need 3x 33r resistors to enable the RAM banks and 8x 10nF capacitors. I used sockets, but they are optional.
Installed it looks like this:
