Here are some pictures i took doing some preliminary testing of the vdc. The normal picture is a program I created to test the vdc registers. The screens with the garbage is a resolution stretching test which corrupts the programs display but maxes the screen borders until the sync was lost. Its around the same resolution as tokra describes (720 x 700i) but this is without playing with the sync pulses and character sizes which I believe is the key to getting past the 800 horizontal pixel barrier. Unfortunately the monitor I was using to push the resolution limits (a Commodore badged Aydin Ranger multisync capable of 1024x768i/800x600) gave up and broke! So it may be possible to get higher, but be careful as it could ruin your monitor! With that in mind, im sure the reverse sync ega mode with some tweaking could produce some high res displays on a modern flatscreen.

Just wanted to say hi. Ive been reading these forums for quite some time now. I dont have much time to tinker with my 128D as I have a full time job. And when Im not there, Im generally working on a PC game that I hope one day to convert to the 64/128.
With that in mind I was going to start a series on my website involving the experiments I was conducting with the 128 and a Commodore ranger 15" high persistence monitor. I was at the point of realizing some new hi res/low res,high colour modes. However, my monitor decided to pack in. Fortunately, I managed to jot down some fairly comprehensible notes before it all went bad, so I should be able to pick it up again at some point.
Currently, Ive made up a lead that lets me view the vdc output on an analog RGB low res Sony BVM 20" monitor, so I can at least still try some tinkering.
I hope I can try to get involved in the small 128 'scene' and come up with something special that I know the C128 is capable of. I mean, look at the C64 demos coming out lately.. I believe they are better than stuff that was coming out on the Amiga 500 initially! If the C64 can do these things then the 128 can definitely do more.
Watch this space then eh? Lol :-)
