A documentation of a popular hardware extension for the Commodore homecomputer floppy disk drives for the C64 and C128 computer.
What's a RAMBOard
Chip Level Design's (CLD) RAMBOards were mostly used for specialised backup tools. Many original game disks were protected by a floppy disk copy protection system, that can only be copied with a full track nibbler (beside sector oriented nibblers). Because an original 1541 Commodore floppy disk drive doesn't contain enough internal RAM, it had to be equipped with additional RAM to let such a full track nibbler work.
Probably the most popular RAMBOard copy tools were the products »Renegade«, »Maverick« and the software of Utilities Unlimited »Super-Card« series since the RAMBOard was built in a compatible way.
Another use of such a RAMBOard is to speed up the transfer rate of the Commodore disk drives by using the additional RAM as a track cache. Hardware floppy speeders of the second and third generation always used additional RAM beside other hardware extensions for that purpose.
