Didn't early Vaxen (11/780) also execute PDP-11 code?? I would imagine
there would have been a PDP-11 assembler, but it might have been a
(RSX?) PDP-11 based one hosted on VMS.? I also (briefly) used the VAX
assembler.? Anyway, there would have been no need for a cross assembler.
The IBMSPL product for Tops-20 came with PDP-11 source code for the
DN60.? I remember building images for execution, typically for simple
things like tweaking the EBCDIC/ASCII translate tables to make somebody
happy.? What would have been nice would have been to change them on the
fly, but we never bothered.? I also fixed a small bug for HASP.? Or at
least I think I remember I did...
All I have now are the DN60 (simulated) JSYS? files, which give an
interface to communicate with the DN60 over the DTE.? These are in
MACRO-10.? No IBMSPL, not front end stuff.? Maybe I'll stumble over it
one of these days.
