Re: CoCoVGA upgrade

Re: CoCoVGA upgrade

So got both D32 and D64 and only one CocoVGA - which one to upgrade and to make it more interesting to the D64 I also have the Dragon 200E lower-case daughterboard which haven't mounted yet. While it's two totally different boards, would it make since to have both cards in the D64?

So just a matter of where...

Re: 4:3 Monitors which support Composite video

Right, finally got the missing screws to mount the VESA monitor stand so the D64 got it chance to show of again even if it has significant more banding issues compared with the D32. So that something I'll need to see if this can be improved. While the Beetronic screen has some various pre-settings m...

Re: 4:3 Monitors which support Composite video

As mentioned, I've been looking at this Beetronics screen as I really wanted to have a true 4:3 screen and I finally came around to fix the Dragon 32 that I have. So with this unit working and getting the right cables from Retro Computer Shack it was time to plugin the system and as well I also test...
