Well, the serial number format matches that of Pacific, a Taiwanese manufacturer. It was made in a year that ends in 8 but it\s not 1978 as the logo style doesn't match known samples from that period. Some of those components look like they could be form the late 1990s but they could be replacements and I don't believe the brand lasted that long. I think 1988 is the best candidate. Sorry, I don't know the model.
