EXPERIMENTAL DISK CONTROLLER: Developed for Microsoft (1996)
For
several years of my consulting activities I was involved in floppy disk
controllers, and their design. Microsoft was in the process of
distributing their software on CDs, but they wanted the security of
some kind of dongle, or other means to control the
installation. A floppy
disk was going to be the key. I made a proposal to produce
a diskette that was impossible to copy, yet was readable by the PCs of
the day and designed this experimental disk controller using two Altera
FPGAs, allowing for custom designs to be quickly implemented. I
wrote all the software, designed the FPGA logic, and did the PCB layout
as well. While the system worked as desired the decision was made
to not use it.
