Nope, definitely cannot fit SOJ sockets. The PCB would need to be a good deal larger. Unfortunately, the swap around of modules will take quite a bit of effort without the sockets.

I wish I knew if these were clones. Below, you can see that on one of the SRAM chips, I whipped a little isopropanyl on it, and the wording faded quite readily. This is a little suspicious. Reference the bottom right corner, and up one IC. On the 3rd module, I'll be taping the IC tops before cleaning the flux off. It is not all that uncommon for lettering to fade from surfaces, so I wouldn't put too much weight on this, but the fading felt a bit quick for just one gentle wipe.

Below are the photos of the black module. I think it looks better on the motherboard compared to the green unit.

I have nine more black PCB's that I've notched out already. I found that this jumper notch helps with alignment when I go to place the module onto the DIP sockets.

In these photos, I used solder paste. But when the system couldn't do 1 ws at 66 MHz, I figured there was a marginal connection, and decided to hit each pin with the iron and some solder wire. It didn't help the situation though.
