[TUHS] Fwd: non-Bell C compiler

Perspective from a friend... Warner ---------- Forwarded message --------- From: Poul-Henning Kamp <phk(a)phk.freebsd.dk> Date: Mon, Mar 11, 2024 at 2:24 AM Subject: non-Bell C compiler To: <imp(a)freebsd.org> I noticed the "non-bell C" thread on TUHS and can add a data point from datamuseum.dk: The Danish Company "Christian Rovsing A/S" evidently had a C-compiler for their CR80 mini computer, and my guess is that they created it in order to qualify for DoD contracts in the POSIX regime. Example C source: https://datamuseum.dk/aa//cr80/80/802c73092.html Listing file from the compiler: https://datamuseum.dk/aa//cr80/ef/ef65339dc.html Listing file from the assembler: http://datamuseum.dk/aa/cr80/32/32ef5456f.html Listing from the linker: https://datamuseum.dk/aa//cr80/17/170304129.html So far we have not spotted the actual compiler anywhere in the media we have read. Mention of C being used for project delivery: http://datamuseum.dk/aa/cr80/1c/1c0b47f0e.html And btw: That one is from a CDC disc-pack which a father+son team has read by building a SMD-USB converter. That project may be interesting in the TUHS domain as well: https://github.com/Datamuseum-DK/pico-smd-controller -- Poul-Henning Kamp | UNIX since Zilog Zeus 3.20 phk(a)FreeBSD.ORG | TCP/IP since RFC 956 FreeBSD committer | BSD since 4.3-tahoe Never attribute to malice what can adequately be explained by incompetence.
