RE: HP Portable Plus ... until 2039?
Could an 8087 be added to a Portable or Portable Plus? Certainly not easily - there is no provision in its circuitry for the addition. That said, I know that circuit boards that plugged into a CPU socket and had sockets for the CPU and a coprocessor existed for various CPUs through the years. Whether that is possible with the 80C86/V30 and an 8087 and whether such a board would even fit in the given case, I don't know. The power draw of an 8087 (non CMOS) would be a concern as well. Any feedback out there?
