Vintage IBM Model 4707 Monitor CRT Compact 9" monochrome VGA. This was POWER Tested, and when connected to standard VGA computer, it gave unreadable images and text.
See the 5th picture.
When I checked further, this is the reason:
((((The IBM 4707 series (including model E01) is a monochrome TTL digital monitor.VGA cards output analog RGB signals (red, green, blue levels continuously variable).TTL monitors expect digital on/off signals, not analog levels.

The IBM 4707 series was built for:
- IBM banking terminals
- IBM POS systems
- Monochrome workstation environments
It is not a PC color display like the IBM 5153 or later VGA CRTs.)))
Physically there is dent on front plastic. See picture 5.
No manual or extra accessories. Only what you see in pictures.
