Convert MDA, Hercules, CGA, and EGA video signals to VGA for use with a modern monitor.
Run your vintage PCs with their native video cards for best old software compatibility.Compatible with actual digital CGA, unlike other cheap "CGA" devices like GBS-8200 which are providing a lag-free conversion.

Monochrome emulation in classic amber or green.

CRT scanline emulation in CGA and EGA-low-res modes.

Composite CGA mode, for many more colour possibilities in supporting games.

On-screen-display controls for image position and EternalCRT

2m EGA Cable (supports MDA, Hercules, CGA, and EGA)

1m USB Power Cable (Wall adapter not included; use a phone charger or USB port)

Tested with an IBM PC 5150, IBM MDA card, IBM CGA card, Genuine Hercules card, IBM EGA card.This is meant for vintage PCs. Industrial machinery often uses MDA-like or CGA-like signals, but the frequencies are sometimes off, and won't work with the EternalCRT. Some video cards also output odd frequencies or resolutions that aren't fully compatible, which could cause a shimmering image, or no signal.No, not all scenes in 8088 MPH will work :p

The current stock of EternalCRT has been upgraded with a USB-C port for power. The product photos don't show this.

Support for your video card, VGA monitor, or capture device, is not guarenteed. I have yet to come across a VGA monitor it doesn't work with however.
