Inside
The inside is divided into three portions, the substrate, the drive, and the
slot.

Uses Panasonic MN50000
Series gate arrays.
Many LSI tips have appeared in the huge substrate.
A memory is 256KB in total in 64Kbit LSI tip x32 piece.
Although CPU is usually called 8086, since it is 8MHz, it is 8086-2 correctly.
The TEST switch and LED for a system test are attached.
Although there is a parallel port, but there is no serial port.
Since a planer is inserted in the slot of a case, there is no connector of a power supply.

It is the personal computer of IBM too that the display board is another.
Although the difference between a color model and a monochrome model is based
on this display board, it is needed.

Mr. Tahara's Machine
The 2nd set of Multistation, 5551-G06 came to hand on 2003.5.1.
I received the computer of having been due to discard from a certain man.
There were no less than 5577 printers with sheet feeder in fact. However, since
there was no place to set, it was not able to obtain. Although starting from a
hard disk is possible, a data error occurs, and even if it is going to read
from a diskette drive, can generate an error and it cannot be read. It may
become a huge ornament immediately...
