Hi Rhys, just looked at your page. I liked the comment:
Using these libraries, it is possible to port and run the old v7 command-line
utilities. Eventually, it should be possible to run the original PDP-11
toolchain as a cross-compiler and hence be able to build an original v7
system without needing to use a PDP-11 emulator to run the old binaries.
Strangely enough, I took a slightly different tack than you did to obtain
the same result. Have a look at Apout at
