[HECnet] C compiler for TOPS-10

Slightly off topic, but I would love to find the ALGOL68C port for TOPS-20. I believe it may have been on a DECUS tape, but I don't know and I have never been able to find it. Does anyone by any chance have a copy anywhere?

Nothing else, I'm afraid. Once I get a few more things straightened out with disk allocation, I am going to continue my quest to download all the DECUS tapes for Tops-10 and Tops-20 and put them on a dual RP07 structure(s). Lots of interesting stuff. If I stumble across it, I'll let you know. Tops-20 has two C compilers that I am aware of. KCC, which is natively hosted and gnu, which will compile for the PDP-10. I don't know if the gnu compiler is natively hosted; another thing I've been meaning to look at. The integration between C and Tops-10 would be interesting. Make isn't directly possible as there are no forks. I guess you'd write a bunch of files into TMPCOR and then go make COMPIL swallow them. I always thought it would be neat to have Tops-20 have in memory files like TMPCOR. However, with a typically loaded system (60+ users), that probably would have been suicidal.

Was it a DEC product or a DECUS thing? Thanks Bob
