( 15 kb )

16 kb

This is the European version of the MZ-800 ROM. The ROM is 16 kb and contains the monitor program 1Z-013B from $0000 to $0FFF),
the European characters from $1000 to $1FFF ( 1st character set from $1000 to $17FF,
2nd character set from $1800 to $1FFF ),
the IPL, floppy disk, and quick disk routines in 9Z-504M from $2000 to $3FFF.

The ROM 1Z-013B allows the MZ-800 to simulate the MZ-700. ROM 9Z-504M is the "real" MZ-800 monitor and contains all the QD / FD routines. Therefore the 800 QD interface card MZ-1E19 and the FD interface card MZ-1E05 does not need an EPROM program.

Willy's Monitor

Willy's MZ-800 Monitor is a powerful monitor for the MZ-800 which has a lot of additional functions, commands, and high expanded routines. It replaces the MZ-800 monitor ROM 9Z-504M and the monitor is compatible to the monitor 9Z-504M except that it does not support any Quick Disk drive. The routines for the QD are replaced by routines which support up to 4 floppy drives.
