Just ran across the thread looking for info on the Sanyo MBC
550/555.

I have a complete system that started out as the original 550 (had
one 360 drive). I upgraded it to the 555 by adding the second drive,
then upgraded to the double sided 800k drives. Installed more
memory by piggy backing the memory chips and modifiying the
power supply current limit sensor, added the PC video display card
to make it more compatible with IBM type programs. Total of 512k
memory.

It came with MSDos 2.11 for Sanyo, Wordstar, Calcstar, DataStar,
Pcwrite. It will run lotus 123 vs1.1. I have upgraded the Wordstar to
the Pro version.

I also have a multitude of "freeware" software that will run on it. I
also subscribed to the Magazine that supported the unit and I have
all of the copies that were issued relating to the 555.

I used the monochrome monitor at first but shifted to using a
Panasonic color monitor that had a pc input and ntsc input so I could
use an external tuner and listen to tv while doing computer stuff and
switch to the video if something sounded interesting.

I also have the schematic diagram for the system. I used a Star
Micronics dot matrix printer at the time.

Fun time and learning experience.
