This device allows you to connect your Apple IIGS to a VGA monitor that supports 15 kHz. Have beautiful sharp graphics on a modern monitor. To find what monitors support 15kHz go to: https://15khz.miraheze.org. Find one that is fully compatible. Mine is a Dell P2214Hb. I bought it on for about $30 and it works great. It's the one shown in the pictures. There are many listed on at this time. Again, this is the VGA adapter only, monitor not included. Just connect it to the RGB output on your Apple IIGS. The circuit board may differ in color from the pictures such as purple.
