Saturn:Super Prologue 21 Model SKC-3000
Super Prologue 21 Recommended Maintenance
Super Prologue 21 is a Saturn built into a Kareoke machine with a VA0 Saturn motherboard. There is a messy wiring harness system inside the Prologue unit with total disassembly required to access the CD-ROM drive which is a common failure point. It is recommended to take photos on your phone overdocumenting your disassembly process in order to reduce pain in reassembly. It is also recommended to unplug, from wiring harnesses, ONE card at a time for recapping.
Main motherboard is a normal VA0 Saturn motherboard with modification to the cartridge slot; the cartridge slot is modified to accomodate the kareoke scsi card subsystem. FRAM modification can be applied. However a region free bios replacement is not recommended as the Saturn uses a unique EEPROM module compared to standard VA0-VA0.5 Saturn motherboards.
