While it *can* be tricky, especially with the ICE-86, to feed non-intel
produced OMF into the ICE, it can be done.  For two years we did this:
	Basic-16(on VAX) -> coff2omf -> ICE-86(PC host) -> 8088 target

The biggest problem was that the ICE-86 made some assumptions
(read shortcuts) in processing OMF, expecting that only Intel's
tools would be used to produce the OMF.  As I recall, the 188 ICE
was not as picky.

When Basic-16 ran out of steam, we switched to the iAPXx86 C compiler.

When that compiler ran out of steam, we switched to MSC:
	MSC5.0(on VAX) -> PharLap Link(on VAX) -> ICE-86(PC host) -> 8088 target

(There was a brief time, when the VAX based tools weren't ported,
that a 386/PC was used as a compile server for the VAX running UNIX).

The options we had were quite limiting.  We found that the
target hardware had *critical* timing requirements.  Of the
development systems we looked at, only the INTEL ICE-86 and iPAT
would reliably operate the hardware.  Intel's own C compiler
at that time was MWC, and it was worse than Basic-16 at code
efficiency and size.  Its probably now the case, that the
third party emulators have caught up; I don't know for sure.
