[Simh] Who Remembers Data General RDOS

[Bob Supnik]

I remember RDOS very well, as I used it to build a mass spectrometry 
system for AEI in 1972-75.  There was a usable Fortran compiler, but I 
don't know if it's on the disk image you have.  All the analytical 
software was written in Fortran; however, the real-time code was all 
written in assembler.

I have the sources for that system, but only on paper, so there's no 
useful way of bringing it back to life.  I also have electronic sources 
for a "memory-only" version that ran under RDOS's smaller brother, SOS. 
This kit has RDOS command files to assemble and link the source code, 
but it won't work under unmapped RDOS 7.5, as there isn't enough user 
memory available.  I haven't tried it under mapped RDOS.
