What is RAMDrive?
 
RAMDrive is a new approach to RAM expansion for the Commodore 64 and 128  computers. RAMDrive may be used as a  stand-alone RAM expander or may be  combined with RAMLink for a more  flexible RAM disk system. RAMDrive  plugs directly into the C-64/C-128  cartridge port and provides a RAM disk  drive system which, when used with the  supplied DOS, is compatible with  standard Commodore DOS commands.
RAMDrive greatly enhances the  capabilities of your system by  providing high-speed loading, saving, and many other standard DOS functions.

The RAMDrive hardware/software  interface provide a high degree of  compatibility to allow vast amounts of  current software to utilize RAM as if  it were a disk drive. RAMDrive is  power-backed to protect the contents  of RAM when your computer is switched  off and has a built-in battery and  recharger to protect data when power  failures occur. RAMDrive will also  work in conjunction with a Commodore  REU on an appropriate multi-slot  cartridge port expansion unit.

Performance
-----------
RAMDrive uses RL DOS to give you the speed you expect from a RAM disk.
Unlike Commodore's RAMDOS, RAMDrive is  not bogged down by constant memory  swaps. This enables RAMDrive to  perform up to 20 times faster than  RAMDOS for most types of file access. In addition, RAMDrive's version of RL  DOS has built-in JiffyDOS Kernal  routines to provide greatly increased  speed and other features when  accessing serial drives equipped with  JiffyDOS.

Compatibility
-------------
RAMDrive's specially-designed hardware  interface combined with the RL DOS  operating system give it the ability  to work as a RAM disk with almost all  commercial software.  RAMDrive's DOS  is active immediatly upon power-up  after the initial setup procedure and  does not require the use of any RAM or  vectors in the computer. As a result, RAMDrive's DOS cannot be accidentally  disabled or overwritten by software. RAMDrive's version of RL DOS also  supports all Commodore DOS commands  (including block reads and writes), enabling it to be compatible with the  many programs that utilize these  commands.

Why Choose RAMDrive?
--------------------
RAMDrive, with its extensive DOS and  power-backed features, is an obvious  choice over any other standard RAM  unit available. For those who don't  need the extensive capabilities of  RAMLink, RAMDrive provides an  affordable alternative without  sacrificing compatibility or speed.
RAMDrive may also be used in  combination with RAMLink to  battery-back a portion of RAM without  RAMLink's optional battery backup unit.
