The RomPLUS card was to be used to allow custom ROMs to be developed. 
The ROM provided added , among other things colored text. I don't think 
many additional ROMs were ever developed, the 16K language cad came out 
and everything from that time on was done in ROM.

One additional ROM chip that plugged into a special card (the ROMPlus 
made by Mountain Hardware, or the ROMBoard made by Andromeda) was made. 
One function was to manage disks in both the 13 and 16 sector formats. A 
call to a memory location would switch between DOS 3.2 and 3.3, making 
file conversions quite easy. Soft Ctrl Systems, the company that sold 
this Dual DOS ROM also sold ROMs that gave instant access to an 
Applesoft renumber and merge program, an Applesoft editor, and a 
specialized disk command menu and disk map
