The board is marked SHVC-CPU-GPM-X3 with a 1990 Nintendo copyright near the CPU.
Any information would be helpful!

Unknown SFC Board shvc-cpu-gpm-x3
Hi all, I recently came across a Super Famicom unit with no serial number on the shell and an unusual board revision I can't find any information on anywhere..no results on Google at all.
The board is marked SHVC-CPU-GPM-X3 with a 1990 Nintendo copyright near the CPU.

Fascinating variant of the Japanese Super Famicom console -- is it a "single chip" or a "three chip" SFC console? I recall seeing the Super Famicom console up & running Super Mario World back in March of 1991 at the Mikado toy store inside Japantown mall in San Francisco. It costed a dollar to try it out for 15 minutes indeed and it was brand new at that current point in time. The USA region Super Nintendo console hadn't been sold/distributed in the USA back in March of 1991.
Back in April of 1993, my local Software Etc. specialty video game store joint had gotten in a brand new Super Nintendo demo kiosk -- the M80C one with a 14" RGB monitor. The screen was super razor-sharp and had a copy of Super Mario World running on it. I was told that I was the very first one to try it out.

This appears to be a prototype or production test board from circa 1990, representing an intermediate design step that may have informed both the PAL board design and the SNS-CPU-GPM-01. The PAL board was the first to merge the sound module, and this board shares layout similarities with both the PAL design and the final GPM boards. (see the extra osc crystal pads on x4)
