HP Portable Plus ... until 2039?

[Michael Fehlhammer]

Power consumption really seems to be a major problem.
If I understood data sheets correctly, the 8087 5 Mhz takes 2.4 W, whereas the PP CPU ( Harris 80C86 ) needs only about 50 mW. A CMOS version of the 8087 is not available.
( There are rumors about an 80C87 from Cyrix, but nobody has ever seen such thing ).
Certainly a reason for HP not to provide an FPU socket.
