Hey John, Thanks for that tip! I don't know why I didn't think of that! I just bought that board (I see he has a couple more). Since I don't need an M8186 board, just the FPU I may be able to sell the board without the FPU. Or put together an 11/23.
Thanks again! - Peter On Fri, Apr 25, 2025 at 2:21 PM John H.
