Inside

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

17 HM6116LP-2 (8513)
18 Parallel port (36-pins)
19 D7261AD (8443E9)
20 D8259AC-2 (8506K3)
21 D8253C-2 (8514E7)
22 SED9420C
23 Keyboard connector

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.


Display Board P/N 6342396, EC 865251-3 [P]

5551G06 D/A

1 CX0-043C 40.0000 MHz
2 MN50015SPG IBM6343870
3 HM6116P-2
4 HM6116P-2
5 HD46505SP-2 HD68B45SP
6 MN50007SPF IBM6343869
7 Monochrome display connector

Uses Panasonic MN50000 Series gate arrays.

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...
