Don't take this personally if you already know all of this, please.
I've never had one, but I'd check for a ROM SIMM on board first, then I'd describe the IC Package size and pin count. Those might be alternate ROM locations, unimplemented VRAM pads or the actual ROM pads if yours shipped with a ROM SIMM.
Just a few possibilities, lots of folks assume pads are for what they'd like them to be . . . they're often not. :-/
Check the DevNotes on the LC for Apple's lamed ceiling limit (comes with the standard "feature package" on all low-mid range Macs
) for the LC. If it's 10 MB, you'll need to use it as virtual memory even if the pads are for additional RAM.
Look for GAMBA in the Peripherals Links Project for the DevNotes.
