The PC-9801 BA2 is a model in the PC-9800 series. It's the successor to the PC-9801 BA

Hardware

The PC-9801 BA2, like every model in the 98 Fellow line, is basically a lower-grade version of the PC-9821 series models; less RAM and no 256 color mode.

Like it's predecessor. The main difference between the now 3 PC-9801 Bx2 models is the the smaller memory for the PC-9801 BX2, the different processor for the PC-9801 BA2 and the CPU clock speed; 25MHz for the PC-9801 BX2, 33MHz for the PC-9801 BS2, 60MHz for the PC-9801 BA2.
