Yes, but IIRC the 8048 series (common in classic computer stuff) doesn't...

My fractional portion of currency is that the 630x is a hitachi varient of the
680x (6800 single chip mpus). I've seen and have some them from older hard
disks and DC300 tape drives that had mechanically expired.

If
you're lucky, eitehr th microcontroller is old enough not to
have any
security features, or they're not used. In which case you remove
the chip
from the PCB and stick it in a suitable programmer.
Even the original Intel 8051/8751, circa 1980, has security
bits. :-( There are ways to get around (at least) those, though.
