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.

I know the port you are describing but on my 128k the port was added
to the battery holder. When I opened the case to fix the floppy and
resolder a broken joint I saw that the SCSI was coming from an add on
card so I'm quite certain this machine has been upgraded. I'm just
trying to figure out if it's a "fat Mac", 512, plus or whatever.
