Modified C64G (LCD, SD2IEC, built-in speaker)

[Vermes]

It is a project of modifications to C64G. The video shows working of LCD.

List of changes:

• SD2IEC (home-made)
• built-in LCD
• built-in amplifier with a speaker

The LCD display was taken from a cheap monitor for the car backwards camera. It has AV input, so it was easy to connect C64. The screen is powered directly from the computer. All unnecessary elements were removed, leaving only the LCD panel and driver board mounted inside the C64.
Here is a small photo and details of home-made SD2IEC. More information can be found at Firmware.

NOTE! When assembling, legs should be bended and changed in stabilizer 3,3V, because there was a mistake in the distribution of terminals.
