It's recommended to use NEC PC-9821Ra43 with a Celeron CPU @ 433 MHz

Somewhat functional, with difficulties primarily in HDD partitioning, peripherals, and keyboard input. Support is mostly focused on the last of the PC-98s, ones with at least 64 MB ram and at least a Pentium CPU.

This device runs an operating system which is known to emulate various devices with EOPs. See the MSX page.

Whether these emulators support operating systems for these computers is unknown; it must be looked into further. PCs without meaningful OSes are not included.
