The hard disk drive (HDD) has a capacity of 100 Mbytes (T5200/100
model) or 40 Mbytes (T5200 model)
The floppy disk drive (FDD) can support 2DD (720 Kbytes) and 2HD (1.44
Mbytes) floppy disks.
The standard memory has a capacity of 2 Mbytes, expandable up to 8
Mbytes maximum.
The plasma display supports high resolution video graphics (VGA
compatible) with 640 by 480 pixels (dots) and 16-levels of gray scale.
The display mode is three mode, CGA mode, VGA-color mode, and
