- World of Commodore VII (Toronto, Nov 30 - Dec 3, 1989)
- ------------------------------------------------------
-
- Once again 8-bit owners were forced to face an overload of Amiga hardware and
- software from dealers, manufacturers, and Commodore. However, there were a
- couple of notable exceptions in the hardware arena.
-
-
- GEORAM from Berkley Softworks
- -----------------------------
-
- Berkley unveiled GEORAM, their 512K RAM expansion board for the C64/128.
- This unit was "developped exclusively for GEOS-equipped Commodores" and
- is used much in the same way a Commodore 1750 REU would be used with GEOS.
-
- Like the 1750, GEORAM isn't true RAM expansion. The RAM is NOT available
- directly to the microprocessor. Code and data must be brought into computer
- memory to be used.
-
- A disappointement is that GEORAM is *NOT* 1750 compatible, and so it can't
- currently be used in place of a 1750 for non-GEOS applications. With the 1750
- out of production, this leaves the SSI 1764 upgrade as the only source of 1750
- compatible units.
-
- Berkley *IS* currently debating whether to release programmer's information
- on the GEORAM unit, so non-GEOS applications can be developped.
-
- The suggested retail price for GEORAM is $124.95.

- Creative Micro Designs Hard Drive and RAMLink Interface
- -------------------------------------------------------
-
- The *BIG* news for C64/128 owners is CMD (the JiffyDOS people) unveiled their
- hard drive, and RAMLink compatibility interface, and they are both
- spectacular!!
-
-
- CMD Hard Drive
- --------------
-
- The hard drive is an intelligent external peripheral, which appears to
- the computer as a normal Commodore disk drive. It contains its own
- microprocessor, and uses no RAM inside the computer.
-
- A great feature is that the drive doesn't contain a DOS ROM. Instead,
- it contains 64K of RAM, and the DOS is loaded off the drive into this RAM.
- This will make DOS upgrades a snap (just run an installation utility).
- Currently only about 32K of this RAM is used by the DOS, leaving plently
- of room for future DOS expansion.
-
- All standard Commodore DOS commands are supported, plus many new ones.
-
- The drive can be interfaced with the C64/128 three ways:
-
- Standard serial: The standard disk serial cable between the hard drive and
- the C64/128. Slow serial on the C64 or C64 mode, and fast serial on C128
- (including burst mode support).
-
- JiffyDOS serial: CMD is well known for their JiffyDOS ROMs which provide
- amazing serial speed improvements. Once again the standard serial cable is
- used.
-
- RAMLink: A multi-purpose expansion device that plugs into the computer
- provides a custom parallel interface to the drive (and much more. More
- on RAMLink below).
-
-
- Transfer speeds:
-
- Standard or JiffyDOS serial: 10-20% improvement over 1581 floppy speeds.
-
- RAMLink (hold your breath): 32K per second on the C64, and 64K per second
- on the C128 (at 2 MHz). These speeds are available for all transfers, of
- any filetype and any operation, unlike Xetec's Lt. Kernal which is DMA and
- only fast for LOADs and SAVEs.
-
- Of course only machine language programs or subroutines will attain these
- speeds.
-
-
- Visually the CMD hard drive is slightly taller than a 1581, with
- about the same footprint, and in an attractive C128/C64c colour all-metal
- case.
-
- The front panel has power, activity, and error lights as well as two
- special SWAP buttons (SWAP 8 and SWAP 9) which interchange the drive's
- device number with any device that currently has device 8 or 9. This
- clearly maximizes software compatibility since the drive can be device
- 8 (or 9) whenever you need it to be.
-
- The rear of the unit has many connectors:
-
- - The power connector to an external power supply (it looked identical
- to the Amiga 500s power supply. How's that for ironic?!)
-
- - Two standard Commodore serial ports.
-
- - A third Commodore serial port for "future printer applications"
- (eg. direct from drive to printer streaming).
-
- - The custom parallel interface to RAMLink.
-
- - An industry standard SCSI connector for hooking up other SCSI devices
- (other hard drives, tape streamer, CD-ROM, etc.)
-
-
- The damage:
-
- Remember, these aren't cheap IBM hard drives, but quality SCSI units.
- You'll be able to move these drives onto any future computer you get, so
- they represent a good long term investment. Nevertheless, the prices are
- excellent considering that no Amiga or Mac user could get a SCSI drive
- of comparable quality for any less.
-
- Standard configurations:
-
- 20 meg: $599.95
- 40 meg $799.95
-
- Custom sizes are available all the way to 700 meg. At the show, several
- BBS SysOps purchased 100 meg versions for $1200. Prices include shipping
- and free DOS upgrades up to version 2.0
-
- First units will available for shipping in early January 1990.
-
-
- RAMLink Interface
- -----------------
-
- CMD also unveiled an exciting expansion device called RAMLink. It
- stands as a valuable device on its own, and also happens to be the interface to
- the CMD hard drive. It doesn't require the hard drive to use.
-
- It's main use is as a 1700/1764/1750 RAM expansion enhancement device that
- offers you some amazing things:
-
- - Built in RAM disk software in ROM (tentatively named RLDOS). It supports
- all standard Commodore disk commands, takes up no RAM inside the computer, and
- provides all the standard Commodore DOS commands. Thus it's far more compatible
- with software than Commodore's RAMDOS. In fact, any software that doesn't play
- with the inside of a drive (fast loads, copy protection, etc.) should work
- with RLDOS.
-
- Since RLDOS is in ROM, and doesn't need to be constantly swapped into
- memory. RAM disk usage is up to 20 times faster than RAMDOS!
-
- - Power, RLDOS activity, and RLDOS error lights (just like a real drive).
-
- - SWAP 8 and SWAP 9 buttons, just like the hard drive.
-
- - The CMD hard drive parallel interface
-
- - Built in JiffyDOS (in case you want to upgrade your floppies)
-
- - Two expansion connectors (one on top, one out the back). One is for the
- REU, the other is a pass through connector for cartridges and other
- expansion devices.
-
- - Internal RAM expansion capability that allows up to 4 meg to be added
- to the RAM disk (it's put in the RAMLink, not the REU).
-
- - It's own external power supply that keeps the REU powered even after the
- computer is turned off, and a battery backup that will maintain the memory
- when the electricity goes out for short (day and less) periods.
-
- Expanded fully, the RAMLink brings up the tantalizing possibility of
- being itself a 4.5 meg silicon hard drive, which would be faster than any
- traditional hard drive on any computer.
-
-
- Price (tentative): $100 for basic RAMLink unit. REU, and RAMdisk expansion
- modules not included.
-
- Projected release: March 1990
-
- No price, or release information is currently available for RAMLink
- memory expansion option(s).

- If you have any comments or questions, please feel free to leave me a
- message.
