The important pins that controls the SRAM ICs also four 4 pins for ground and VCC remains the same but checking the 3 different makers of 128k x 8 sram chips has different data lines numbering but all data pins are physically same for 32 pin SOJ IC package.

What gives?

it doesn't matter which sdram connector data bit goes to which memory chip data bit.

Right to repair is fundamental. You own it, you're allowed to fix it.

Yeah, I thought that same thing. I learned to read schematics and data sheet for decades till now.

Was not sure.
