At one point I acquired a 486 Magnavox with identical MOBO and DB. Different BIOS (logical: 80486). Instead of a 486SX as indicated on the case it had a 486DX installed. Performance was very poor for a 486 though (286 MOBO really and early VGA). It died so I recycled it. The chances of finding another one are very slim: 486s did not sell that well yet in the early 1990s (extremely expensive). Good luck.
All Magnavox computers and peripherals are really Philips products BTW. Philips was a pioneer in optical media.
