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. Unless the Specific Kareoke BIOS EEPROM is region patched do NOT place a regular region free EEPROM in the socket.

Super Prologue 21 is a Saturn built into a Kareoke machine with a VA0 Saturn motherboard. This page covers the SKC-3000 variant. Not other variants. Other variants are different interally but overall are the same; a Kareoke machine using Saturn as a processor.

Common failures include no power, black screen on powerup and not reading discs. Overhauling a Prologue 21 should not be taken lightly and only approached by absolute experts with a very large amount of experience.

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 and then connecting the wiring system back to the card. Rinse and repeat.

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. Unless the Specific Kareoke BIOS EEPROM is region patched do NOT place a regular region free EEPROM in the socket.

Roland 01-HR-SE Harmony Board

Should have a Sega logo somewhere along with "SKZ-0001 835-12275".

For this card you can use through hole capacitors fine provided they're pushed downward and position strategically.

SCSI Card plugs into modified VA0 Saturn board. The HDD connects to this card. On this special 'sandwhich' card is full of RAM and SCSI LSI. It is two cards connected together with a connector.

If using radial capacitors keep in mind the capacitor legs must be very carefully trimmed so the card can be closed together again.
