Miscellaneous TeraDrive Information

The material below is a rough machine-translated excerpt from a Japanese blog entry by nyanonon, dated 27th April 1994, about miscellaneous TeraDrive information. Some lines are clearly awkward, so I am preserving them as translated source material rather than rewriting the author’s claims into polished modern English. The original entry...

Sega TeraDrive Tidbits

The IBM Personal System/55 5510

While looking into the Sega TeraDrive Model 2, I came across a fascinating Japanese look inside IBM’s PS/55 Type 5510. It is one of those machines that looks familiar at first, until you start paying attention to the motherboard and cables. There is some wonderfully peculiar hardware in here!

Sega Saturn Sophia SIMM CART DIP Switch

Here’s a test of the SIMM CART switch on SW2 at the front of the Sega Saturn Sophia Programming Box. My first interpretation was that it simply selected between the internal SIMM memory and the Saturn cartridge slot. Sega’s development documentation shows that it is more complicated than that.

Sega Saturn Sophia 171-6692B SH-2 Power Cable Adapter

Any other console, I probably wouldn’t bother mentioning this, but since it is Sophia, she gets a mention. My 171-6692B SH-2 CPU cards are not quite the same as the better-documented 171-6692D boards.

Sega Saturn Sophia Programming Box Mainboard Repairs

After the A-Bus capacitor replacement failed to improve Sophia’s condition, I moved on to the mainboard. I’ve now replaced most of the electrolytic capacitors there, and the result is considerably more promising. The Hakko 808 works wonders on these old boards.
