Re: Devpac QL

What I asked in my email was:

Is it possible to have Devpac QL binaries released as public domain, or even, open source - if the source code is still available somewhere.

Norm.

Yes, back in college in 1982-83 I was taught that. I was on the National Computing Centre Threshold Scheme at the time. The correct spelling never looked right though.
