Contact Graham
Does anybody know of a way to contact Graham of Oxyron/Arsenic, I don't seem to be able to PM him here, and I would like to ask him some questions about the VDC. |

Surely some of the Oxyron members are in contact with him. Check with Yazoo or Axis |

Quoting StrobeDare I ask what you want to know about the VDC?
I've posted my questions here https://c-128.freeforums.net/board/9/vdc-programming
I was originally hoping it was possible to get 4pixel wide attributes while in double pixel mode. However for now I will simply be content with knowing how I can get 40/32 chars working on any colour... as it works, but then I change the background colour and garbled rolling screen.
Any info on clocks per line/screen. When and how it does DMA etc also greatly appreciated. Working out DMA should be simple enough for somebody with a good enough logic analyzer. |
