The A20A 86-89 Accord/Prelude PJ0 ECU had many revisions in different countries. Some of them will lack an O2 sensor or EGR control. However, they all use a vacuum advance distributor.
Most those ECUs were made by Matsushita. Some of them (86-87?)use an external 128k ROM.
The California Emissions PJ0 were OKI 80C154 based and always use a 128k External ROM
