      Nope. The P/370 card is 8-bit XT bus. The PC Server 500 is MCA. It's
      a MCA P/390 card. That's a standard configuration for an MCA P/390.

      Yes, but the P/390 is much newer and much, much faster. The P/370 was
      370/XA architecture while the P/390 is ESA/390+. The P/390E, which came
      later, is 31-bit z/Architecture.

      I actually have three of these mainframe-on-a-card machines. Two P/390
      PCI's and an R/390E (the last generation of P/390 technology in a RS/6000).
