Seems there is another version of the edge connector available.
I think it's easier to get, and cheaper, so maybe you could make another branch for this?

Hello!
Soldering SOJ-Chips is not easy. So I made a hack:
I soldered some Female PCB connector, like this one:
https://www.atd-shop.com/qx22B3-en/female-header-rm-127-mm-smt-single-row
on the PCB, bended the pins of the RAM-Chip into shape and put the pins in the
connector. Its like a socket, but much easier to solder. It works without Error.

HI Mr Sukkopera
Ive noticed all of the Data lines are switched and don't follow the Amiga Schematic, D0-15 and UCAS/LCAS.

Received this PM from AmiBay user go0se:

Hi SukkoPera,

I just wanted to report that I had success with the ICSI IC41C16257-35K chips with your A600 Chipmem expansion:

If you want to update the GitHub 'Tested' column for this chip

Cheers.

Just want to let you know, that I couldn't get Epson RTC62421 chip, but I found a pin-to-pin equivalent: OKI MSM62X42BRS, and it works perfectly in your design
