MCDISK-E
USER'S MANUAL
PCMCIA/JEIDA CARD READER/WRITER WITH SCSI INTERFACE
The MCDISK-E (Memory Card Disk) is a two slot card reader/writer for PCMCIA/JEIDA compatible memory cards. Two card
slots allow for simultaneous use of memory cards. The MCDISK-E can handle a wide variety of cards of any size: SRAM, ROM,
OTP, E(E)PROM, FLASH, I/O and PC-ATA disks. To interface those cards to the host equipment it has an SCSI interface. The
SCSI interface is widely used for connecting mass storage devices like hard disks to microcomputers.
A memory card can be thought of as an extremely fast disk storage device, because there are no latencies for moving
mechanical parts like read/write heads. In all other aspects however, a disk device and a memory card are much the same.
The MCDISK-E exists in two versions. The first one is equivalent to a 3.5" Floppy drive which can be easily incorporated into
OEM products. The second one is a desktop case with built-in power supply for easy connection to all computers with a SCSI
interface. However, although the reader/writer device is compact and economically priced, no concessions have been made
in its performance. It provides a fully professional yet highly economic solution to demands for data storage in harsh
environment. This makes the MCDISK-E ideal for use in many industrial and business applications with SCSI data input and/
or output.
