Like the MK9 before it, the MK10 refers to various PC specifications used for Pump it Up. As of 2023, this is the latest boardset.
These are all standard off-the-shelf PC parts with a custom USB IO board to interface with the cabinet lighting and dance pads. The IO board, unlike the one used between the MK6 and MK9, is only compatible with Pump it Up PRIME 2 and newer.
Specific board compatibility varies from version to version, but the game is generally lenient on which parts work provided the game's OS supports the board's chipset, sound/Ethernet controllers, and the installed GPU.
Known compatible motherboards:
ASRock H81M-DGS R2.0
H310M-based motherboards (XX and up only)
Gigabyte H610M-K (XX and up only)
Known GPUs:
GeForce GT 710
