+===== ROM-MJS for Multicomp =====
+There are two versions of ROM-MJS for the Multicomp (Z80).
+The first version (version 1) Utilises Grant's existing monitor to boot. The intention was to replace his CP/M implementation with the Extended Monitor to provide more utilities as well as PC partition support.
+The monitor and Hardware Access Code were packaged along with a loader code and copied to the location on the disk where Grant's monitor expected to find CP/M.. The loader then moved the various code sections into RAM and passed control to the monitor. A partition table was also created to allow PC style partitions to be utilised.
+As the monitor grew and additional features were added the memory model Grant used was no longer suitable and a new boot system was created.
+[TBC]
