Gratop: Top Graphic by Andreas Haschke & Norbert Raschdorf

[ComSoft6128]

Excellent German mode 2 screen editor from 1986 for the 464 (with disc drive), 664 & 6128.
This started life as a type-in in 'CPC Magazin' .
In this video I load the sample screen (provided by Kukulcan at CPCPOWER) modify it and save it. 
After a soft reset I then use the VIDI Rom to display both screens.
