Jonathan, I tried to make a 720K bootable floppy with one of the programs here in the libraries, then ran one of the software emulator demos and got the message "Not a system disk or boot error", so that made me unsure of the need for a hard drive. I used a regular double sided double density 3.5 disk to do this, so thought maybe I needed to use a high density disk. I haven't went out and purchased one as yet though. Are you familiar with these emulators and making these bootable disks? Randy
