Is there any open source/freeware TSO/ISP clone for PC?

Question

Free as in beer. I can live without the source code.

About 10 years ago I saw a commercial product. Is there anything free now?

I found Gispf on SourceFOrge, but there are no downloads. Otherwise I Can't find a thing.

Edit: I'd prefer something approaching the whole system, but could manage to live with the editor

Edit" TSI is "the old Time-Sharing Option on IBM mainframes"
