You can enter commands. - If you have a floppy mounted, it will boot from the disk. - - The system could support 1 or 2 5.25 or 3.5 floppy drives, although 3.5 - was the recommended hardware. Format is similar to the PC 720kb, except - it has 5 sectors of 1024 bytes, giving 800kb total. We only support the - 3.5-sized disks. - - TODO: - - Cassette interface (coded but not working) - - Use kbtro device (tried and failed) - - Optional serial device Z8530 Z80SCC - - Optional SCSI controller NCR5380 and hard drive (max 40mb) - - Joystick - - Audio: it could be better - - DAC output is used to compare against analog inputs;
