Sega Tera Drive
| Preliminary Information | |
|---|---|
| Release Year | 1991 |
| Leak Risk | Medium |
| Batteries | None |
| Capacitor Types | Through Hole |
| Destructive Entry | No |
The Sega Tera Drive is an early Japanese DOS/V computer which consists of an IBM PS/55 (the Japanese variant of the IBM PS/2) and a Sega Mega Drive on the same motherboard. The two systems can communicate with one another, in contrast to the Amstrad Mega PC. At this time, only two commercial titles are known to use this capability: Puzzle Construction and The Manhole. Puzzle Construction has a game editor on the PC side, which runs games on the Mega Drive side. The Manhole is a PC game which uses the Mega Drive's Yamaha OPN2 for FM synthesis.
The power supply commonly fails, and its capacitors are listed on the linked wiki page.
Known Issues
MD/PC or Video Mode Switches Are Glitchy / System Randomly Resets
Causes
- The switches have failed
- The switches have cracked solder joints
Solutions
- Replace switches with new ones
- Resolder switch pins
Video Glitching / Unable To Maintain Horizontal Refresh
Causes
- Out-of-spec capacitors
Solutions
- Replace capacitors
Noisy Mega Drive Graphics
Causes
- Bad PCB Design
- Low quality custom chips
Solutions
- None yet. The Mega Drive Triple Bypass needs to be adapted for this system.
Disassembly Notes
The board is somewhat tricky to get out the first time you try. Also, the front face plate requires an unreasonable amount of force to remove, and must be done carefully to avoid breaking the tabs.
