MDGFX V1.1 Genesis/ Megadrive RGB bypass LT6557

2 layer board of 2.30 x 1.00 inches (58.5 x 25.5 mm)
Uploaded: October 01, 2020
Shared: October 01, 2020
Total Price: $11.50

Made during the covid pandemic when I couldn’t get my hands on a console SCART cable or THS series RGB amp for a bypass.

The top R/H resistors should be 20 to 25ohm 0805 for .7vpp output

You can get 20/22/24/25 it probably won’t make much difference - Likely to the decimal point on your overall output.

Please note: although developed for VA4 model 1 megadrive (hi def labels) I couldn’t get rid of the jail bars completely. This will be re-attenuated for other projects

Here is an installation guide for VA0/ VA1 model 2 megadrive/ genesis with MB3514 encoder:

These are taken on a Sony PVM-2053MD on a 60hz modified PAL VA1/VA0 model 2 (can’t remember, they’re the same anyway) with all settings centered. It’s a $5 cable. It’s also using the CAT5/ BNC screwdown adapter to convert to PVM inputs which I’ve shared.
