[Simh] Interdata 16-bit diagnostics

[Davis Johnson]

My background is mostly the Interdata/Perkin-Elmer/Concurrent 32-bit 
systems. I'm really light on the 16 bit iron. I do have a 6/16 with no 
periphials that I run blinking light programs on, however.

I've looked ever so briefly at running 16 bit diagnostics so that I 
could regression test the 16 bit systems after breaking the 32 bit 
systems. I didn't get very far. I've been hoping somebody like you would 
figure it out for me.

The paper tape diagnostics come one to a tape, and were directly 
bootable. You put them in the reader, entered the "50 sequence" in low 
memory and started at address 50. I'll try to provide usable details 
later when I actually have time. Probably this weekend.

The 32-bit assembler that comes with OS/32 will assemble 16 bit code. 
This doesn't directly solve your problem, but you can use it for comparison.

I may be able to find some source code to feed your assembler. Not much, 
unfortunatly. The basic interpreter source would be good. It was 
distributed in source for some odd reason, but I don't have it. The 
FORTRAN IV compiler would also be big chunk of source.
