<<Were you able to successfully run online diagnostics, both on the HP-IB peripherals and on the HP-IB card itself?>> Yup. I didn't do exhaustive testing, but HPIBDIAG, CIPERLPD, REELDIAG, and HPIBDDS all seem happy, including device identification, self test, and (where appropriate) read or read/write tests.
