Yes, you'll need System 2.0/Finder 4.1, since how much RAM a Mac had was irrelevant prior to the introduction of the 512K.
Physically, If you've had it open, can you describe the board the SCSI cable is connected to? Is it only a small square board connected toward the back, or is it a large board that covers the entire front half of the board? If an add on RAM board towards the front, most of them required a minimum of 512K on the main board. It could have been upgraded by a third party, or a board swap. Check for a blue 512K sticker on the rear of the logic board, or look for two distinct model numbers on the right edge. If none of those markings, and you don't have a board covering the front half, check the two rows of RAM chips for the numbers 256, or 64. If 256, then then it's stock 512K. Any add on RAM boards are likely going to hold around 1-2MB, typical for 512K upgrades.
