In a similar vein to byuu's SNES Preservation Project, but just focusing on emulation instead of archiving the software (people already do that for the PC,) I have become determined to create IBM5150, in the hopes that it will one day preserve the PC, clones and descendants, in the best possible manner. My 2-man (so far) team has made quite a bit of progress so far. However, for the future, we'll need more.
