Compaq Deskpro Part 2: More exploration and fixes

Part 2 of my Compaq Deskpro series. Following up, I get the floppy subsystem working properly. I add a custom made upper memory ISA card to the system. I take a deeper dive look at the No-Slot-Clock and get that working. I explore the capabilities of the Compaq video card in this machine and I respond to some great viewer comments on controlling the speed of the machine.
