An alternate solution might be instruction emulation.
There were DOS TSR's that emulated missing instructions
using the processor's invalid instruction interrupt.
The TSRs I was able to locate are listed below. I've
never used these, so I'm not familiar with them. I think
there was one for 486 too, but I'm not able to locate it.
It's possible Rugxulo or someone else might be familiar
with some emulators for 486. You might try a post to
comp.os.msdos.programmer and comp.os.msdos.misc, etc,
in case someone remembers.
It's also possible that you could find enough support
in those listed below, although unlikely...
Also, these are from old and obscure DOS websites like
Garbo, Simtel, Hobbes, Funet.fi, so do a virus scan
before using.
