Home of the original IBM PC emulator for browsers.
NOTE: Disk Optimizer was distributed on a copy-protected diskette. We have created a Kryoflux copy of the diskette in our possession (shown below), and it’s clear that track 16 has some unusual characteristics, but until we have time to analyze the diskette and software more closely, it will not operate in the PCx86 emulator as intended.
