Let's put this question to the >test. >I can think of one, so I'll start: > 1) GECOS / GCOS / GCOS 8 > for the GE 600 / Honeywell 6000 / DPS 8 series Here are two very well known ones: 2) MVS/XA for IBM S/370 series 3) VM/CMS for IBM S/370 series There are some similarities between these two operating systems, but there are major differences too. There is a Japanese workalike for MVS, but let's ignore workalikes. The S/370 range can run System V (Amdahl's UTS) and SunOS, but they haven't got this linker problem (:-). There was a C compiler for TOPS-10 on the DEC-10, but I guess we can regard TOPS-10 as dead and not count it. One more, and we'll be there! But the question is not the number of _system types_ but the number of _implementors_. I know of four C compilers for VM/CMS, and I'm sure there must be more in progress.
