Re: Unknown Dragon Star Trek Game.
This looks massively like a type-in Star Trek game I spent a lot of time with too, though I'm not sure if I still have a copy. Will check my basic program disks.
Update: Sadly no joy. Have tried to recall what magazine it might have been from. I would guess Your Computer or PCN?

Re: Dragon 32 RGB SECAM and video tests

Re: Dragon Meetup 2021 - November 27th/28th
If people can do Lateral Flow Tests before attending that would be helpful. Yes... they are more than a bit flawed in terms of sensitivity (about 1/3 for asymptomatic individuals) but it's still a bit better than nothing. A friend held an event where LFT's were required for attendance, and they put ...

Re: Anything OS9 level 1 data retention time
Oh, looks like I made a bit of an assumption there.
Just because a list of modules exists, doesn't mean that list corresponds to the contents of any available archive. Ah well, back to thinking about the stub mechanism!
