Hi Sven
I can't help feel that you've missed the point of wanting to port UNIX
edition 6 or 7 to the PC. Its a challenge, nothing more, nothing less. I have
run both editions on Bob Supniks excellent emulator (now with PDP-10 support
BTW) and they're great, but it'd be ultra cool to boot it directly on a PC.
I would guess that VMWare would be a great host, or maybe its open source
equivalents (Plex86 or Bochs) so that you could save the reboot cycles. I
would also try porting V7 instead of V6, at least initially. With so much
open source code out there, it'd be a relatively simple task to find C code
for IDE disc access and such like. I would even suggest getting older Linux
code from the 2.0.x days as its likely to be a little less complex, while
still being stable.
Just my 0.02 EURO.
