[Simh] Interdata OS/32 kit

[Davis Johnson]

I find it encouraging that there is interest in OS/32.

My recollection is that the Whitesmiths C compiler requires a 3200 
series other than the 3220. Specifically it uses the commercial 
instruction set and more than 1mb of address space.

I have a modified SIMH that passes all 3220 relevent processor and 
memory diagnostics except for double precision floating point divide. It 
doesn't have enough guard digits so it sometimes rounds wrong. It runs 
OS/32 R09-2 quite well. It is criminal that I didn't offer it to the 
group before I drifted away from it.

Unfortunately I haven't worked on it in way longer than I'd like to 
admit. It needs to be reintegrated with current main line source. I 
think this will be one of my corona virus projects.

I had a road map where the next step would have been to support the rest 
of the non-S bus machines except for the 3205 and 3203.
