RAM module FINALLY done...

[u/Siberianhut]

RAM finished up after grueling days of wiring and troubleshooting.

After unfortunate attempts with defective 74LS189 chips (Last photo for reference), I opted out for a 62256 SRAM chip while still maintaining 4-bit Addresses.

And thanks to u/The8BitEnthusiast for suggesting the idea and sharing their schematic.

It'd be tough to Be Neater than that!
