RAMLink Info          

RAMLink is multi-purpose interface for  both the Commodore 64 and 128. RAMLink  plugs directly into the expansion port  (cartridge port) of these machines.

RAMLink will allow you to use your  current RAM expander, RAMCard, or a  combination of both as if it were a  standard disk drive attached to your  system. Software for configuring, partitioning, copying files and whole  disks, and GEOS compatibility will be  included. Compatible RAM expanders are  Commodore 1700, Commodore 1764, Commodore 1750, Berkeley Softworks  GEORAM, and PPI/CMD RAMDrive. Quick  Brown Box static RAM units cannot be  used in the RAM port, but may be used  in the pass-thru port. RAMLink will  also contain an autoboot feature for  both 64 and 128 computers which will  allow booting of any file located on  any device and drive. RAMLink will  include a complete users manual for  RAMLink and a JiffyDOS users manual.

RAMLink is compatible with most  cartridges via the Pass-Thru port,
though it may not be compatible with  all functions or features of the  cartridge. RAMLink is not compatible  with the Schnedler Turbo Master CPU or  the Xetec Lt. Kernal Host Adaptor.

RL DOS (RAMLink DOS) Features
-----------------------------
* Supports all standard Commodore DOS commands, including direct access commands and job queue codes
* High speed file access routines, up to 20 times faster than Commodore's RAMDOS
* Supports partitioning of RAM into several logical drives (up to 32)
* Partitions may defined to emulate physical drive types (1541, 1571,
  1581) or may be CMD Native types.
* Native partitions may contain up to 16 Mb and support true subdirectories
* Software command may be used to disable JiffyDOS routines

RAMLink's Optional RAMCard
--------------------------
RAMCard is an internal RAM expansion  board which may be plugged into
RAMLink. This allows you to use RAMLink  as a stand-alone RAM disk without any  other type of RAM expansion unit. RAMCard may also be combined with other RAM expanders to allow you to have  additional RAM. This allows for the  widest flexibility in your system.

If you have, for instance, a 1750 REU  and RAMCard with 1 Mb, you may  configure your system so that when the  Normal/Direct switch is in Normal mode, you have 1.5 Mb of total RAM disk  storage. If you switch to Direct mode you will have 1 Mb of RAM disk and can  use your REU with software which  recognizes it as an REU. It's contents  will still be power-backed by RAMLink's  power supply, or battery-backed by the  optional battery unit.

RAMCard uses industry standard SIMMs  (Single Inline Memory Modules). Four  SIMM sockets are provided and can  accommodate either the 1Mbx8 or 4Mbx8  SIMMs, giving total capacities of 4 Mb  (using 4 1Mbx8 SIMMs) or 16 Mb (using  4 4Mbx8 SIMMs).

RAMLink's Optional Battery Backup Unit
--------------------------------------
The RAMLink Battery Backup Unit will  allow the contents of any RAM installed  in the RAM port or on RAMCard to be  preserved in case of power failure. A charging circuit is contained in  RAMLink to keep the battery charged  whenever RAMLink is switched on. The battery can preserve RAM contents  for short durations only, from 6 to 23  hours depending on the amount and type  of RAM installed.

Warranty on all of these products is 90 days from date shipped.
