More likely superceded by the 4052, which used a bit-slice processor
rather than the MC6800 that the 4051 used. There were some other minor
improvements also, as I recall.

The 4051 might also qualify for the race of an early personal computer if
its $10,000 cost doesn't put it out. It was programmed in the nicest
BASIC that I have ever run across! Marvellous vector graphics. But
SLOOOOOW! The real queen, though, was the 4053 with its 19" (17"?) screen!
