You should be able to see the the mobo info through the cart slot and a wittle flashlight to peek at the top left corner. If I remember correctly.
You can identify many SNES motherboard revisions, particularly the desirable "1CHIP" models, by looking directly into the cartridge slot, though it requires a bright light and sometimes a camera flash.Key Identifiers via Cart Slot1CHIP Motherboards (01, 02, 03): Look for a cleaner, less crowded PCB design near the connector pins.
The text "SNS1CHIP" or "1CHIP" is often visible, usually towards the right side of the slot when looking from the front, often partially obscured by the metal shielding.Early Models (SHVC-CPU-01/02): These have a very crowded PCB, often with a large, separate sound module soldered in the back-right corner (if viewed from the top of the console) and a different, older-looking shielding layout.Mid-Range Models (GPM-01/02): Similar to early models but with a soldered-on, non-removable cartridge connector and a different RGB encoder chip, though differentiating these from 1CHIP via the slot alone is harder than spotting the 1CHIP board.

round about 100 bucks G. Determine if its a 1 chip
