A great way to maintain your own data on a hard disk is to put this

"re- image" your drive with the combo image without overlaying the data
stored in the slices beyond the first 6. Just be very careful to use

Also remember to calculate the maximum number of slices your hard disk
will support and do not exceed this number.
**WARNING**: The combo disk image includes a partition table at the
start of the image. If you re-image drive with the combo image, you

partition table (using `FDISK80` or other partition management
software), those changes will be lost if you re-image your disk with a

## Assembly Language Programming for the RC2014 Zed
Bruce Hall has written a very nice document that describes how to
develop assembly language applications on RomWBW. It begins with the
setup and configuration of a new RC2014 Zed system running RomWBW.
It describes not only generic CP/M application development, but also
RomWBW HBIOS programming and bare metal programming. The latest copy
of this document is hosted at
