Subject: Stamp Drive, PCMCIA hard disk, flash, ??

I saw the following ad in Nuts and Volts and wondered whether anyone has any experience:

"DESCRIPTION
-----------

The MVS Stamp Drive (SDRV) is an RS232 to ATA adapter that allows any
controller with a serial port to read and write PC compatible PCMCIA,
Compact FLASH, and Hard Drives. Mounting holes and stacking connector are
compatible with the MVS Credit Card Computers and Single Board Computers. Small size also makes it a perfect match for the MVS Single Chip Computers
and the Parallax Stamp. Lower cost models are available for IDE interface
(PCD1), ISA bus (PCD1a), or PC104 bus (PCD1b).

MVS PLUG-N-GO means the card can be plugged into a PC for testing and works
right away. The PC is used for power and download. No costly development
kits, cables, or power supplies! Single-wire Multi-drop Long-distance
Network (SMPLNET) is available allowing many modules to stack efficiently
and talk on one wire. A standard PC RS232 port can also share the wire.

SDRV works with PCMCIA Flash or hard drives and also Compact Flash (CFA)
using a low cost adapter. This is usually included with the card, camera,
or palmtop or can be purchased separately. The newer and thinner "Smart
Card" and "Memory Stick" types are also supported with adapters.

Reading and writing is accomplished via simple user friendly ASCII
commands. These are easy to produce from a standard comm terminal for
debugging and can be efficiently sent from small microcontrollers that have
limited memory. Only 3 commands are needed: INIT, READ, and WRITE."

The link is at http://www.star.net/people/~mvs/SDRVSPEC.TXT. The ad claims sppeds of up to 115.2kbps and a qty one cost for an eval kit of $95.
I'd be interested in any comments or experience.
