Excellent work, congratulations
Maybe you were lucky, but what matters is that it has started, from there you can make upgrades if necessary to adapt it to your needs.
However, it could also be that the RAM was the problem with the failed startup, I don't know if you had already tried that module, for future (possible) upgrades, I recommend using RAM with identical chips.
AMD 286-16 287-10 4MB HD 45MB VGA 256KB
AMD 386DX-40 Intel 387 8MB HD 81MB VGA 256KB
Cyrix 486DLC-40 IIT387-40 8MB VGA 512KB
AMD 5X86-133 16MB VGA VLB CL5428 2MB and many others
AMD K62+ 550 SOYO 5EMA+ and many others

Excellent news! A New Year's gift.
