Someone from C/A care to correct that?

Being up at odd hours, and tired of not knowing who had done what, I called MetaComCo (England, not CA), and asked. I was wrong, Jim was right. The file system & some other misc. parts are MetaComCo; the exec (message passing and etc.) are C/A. The exec was written and the OS on top of that was not finished. The C/A exec and the MetaComCo exec were enough alike that there was little trouble putting Tripos on top of the C/A exec. I also took the opportunity to ask for tech information on Tripos. Supposedly, they've put stuff in the mail to me. Be interesting to compare that to AmigaDOS. Finally, the original Tripos (as done at Cambridge) is PD. Not sure what it takes to get a copy, but you should be able to if you want. For those interested in chasing this, the number is 011-44-272-428-781.
