While searching for odd MSX-DOS versions I came across this COM256 program. It seems to offer some bank switching / multitasking system for machines with 256K or more. I don't have any clue on how to operate this.

When viewed in a hex editor it turns out to be a modified COMMAND 1.11 (Hal-F edition, the one with the bug), with some extra code at the end. There are no extra commands. I tried renaming it to command.com but that wasn't a success. It starts twice and then hangs.

I found it at the MSX Nostalgia site as disk 174. Who can tell me more about its origin and purpose?
