FEATURE: Video support for VAXstation 4000 series #407

It looks like the VAXstation 4000 VLC and VAXstation 4000 Model 60 emulations don't have video support yet. It'd be neat if someone implemented this.

Feel free!

Where I come from, feature requests are welcomed by projects even if they're not something someone wants to specifically take on at the moment because it's better to keep track of what people might like than to just drop it on the floor. They can even provide good fodder for people interested in doing something useful for the project but who don't have any specific ideas to start with.

As I have said many times, if I were allowed to by my employer, I would just do this myself. However, doing it on my own will have to wait until I retire.

They are welcomed by the project. Note that Mark's comment is not a statement from the project. I didn't know about your employment difficulty, but I understand that. Some employers consider everything done by employees their property, while others take the sane view that this doesn't apply if it's outside the scope of the business and done without company resources and time. I'm lucky enough to be in that second category. In any case, I'm hoping that someone with relevant knowledge and time can take this up. I don't know who that might be.

If it's helpful at all, NetBSD includes drivers for both LCG and SPX graphics as part of its VAXstation 4000 series support. There's at least enough information in that code to get something working with NetBSD, which would be my own first step in implementing support.
