I'll leave that decision to you :-) The publications page isn't overly crowded, so I don't see any big problems with leaving them there for the time being.

Currently, this repository only contains VDKDUMP, a program that reads a DragonDos diskette and dumps it to the serial port in the VDK virtual diskette format. The program is really small and the code...

Re: Hello from another new member

Jedie, Do you have any experience to share for any of these converters? I'm using Grand Video Console from Grandtec with decent results (composite to VGA). I've also tried other solutions, but some of them introduce a latency close to one second. Suitable for video playback, but not for interactive ...
