I have a board with uPD70F3554 chip on it. I would like to buy the original UPA USB from elra soft, but first want to confirm that i can find the pins on the board somewhere. I have a pin out from the chip.
Can somebody with original elrasoft UPA USB tell me what pins are required to write to uPD70F3554? I can then check for continuity on board to chip pins to find someway to write. I want to be sure i can find pins on board and not desolder chip before buying UPA USB.
Thanks
