'Twas PC Plus.
A little story of my adventures with OSs:
I originally got into Linux because I couldn't burn CDs from within Windows. I tried it to see if GoCombust (or whatever it's called) would work. It didn't, so I thought 'Hey! Since I'm on a roll of trying different OSs, lets give this QNX a go'. I installed it, found that nothing else would install, so got rid of it again!
The only reason that I'm thinking about it agin is that I thought I'd try something more adventurous. Since QNX is a UN*X bases OS aswell, I thought I'd try 'porting' something to it. Just for my own amusement, not for any real gain! Haven't got very far as I still can't install any software. It's not a vital thing - I'm sure I could be doing some Uni coursework or something
. Cheers though.
