Notes:

  1. No official announcement date. The 386-based complexes were shipped with "special bid" machines only - namely the 8590-402 "PS/2 Model 90 XP 386".
  2. According to the FCC records the T0-/T0 applications failed. It's however possible that it passed as an integral part of the ANO8590 Model 90 386 application.
  3. "H" and "L" share the same PCB, external clock, and FCC ID.
