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. =20

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.
