PCD-897/PCM-3840 ® DiskOnChip 2000 Flash Disk Card/Module Introduction ® ® The PCD-897 DiskOnChip 2000 Flash PC card is a solid state disk The DiskOnChip 2000 provides a Flash disk (BIOS expansion (SSD) in a standard 32-pin DIP package. It is a fast and economical only) which does not require any bus, slot or connector. Simply ® Flash disk for embedded systems, Internet devices and portable insert the DiskOnChip 2000 into a 32-pin socket on the applications with limited space and modest disk capacity PCD-897/PCM-3840 or a CPU board and you have a bootable Flash requirements. It features an ISA connector and can be installed into disk. Its low power consumption and small size makes it the ISA backplanes, CPU cards and motherboards. optimal solution for single board computers. ® The PCM-3840 is a PC/104 form-factor solid state disk module. It DiskOnChip 2000 is bundled with M-Systems’ industry standard ® includes all of the same features as the PCD-897 but is especially TrueFFS (True Flash File System) software for full read/write disk ® suited for embedded computers in industrial environments. PC/104 emulation. TrueFFS provides hard disk compatibility at both the modules connect to computer systems through a standard 104-pin sector and file level. It works in a variety of operating system connector and can be either stacked upon other PC/104 modules or environments including DOS, Windows 95, pSOS+ and QNX. In ® CPU cards or mounted on special carrier boards. addition, TrueFFS incorporates features that ensure data integrity and reliability. ® The PCD-897 and PCM-3840 use M-Systems’ DiskOnChip 2000 ® single-chip, solid state Flash disk. It incorporates a new Flash M-Systems currently manufactures DiskOnChip 2000 products at ® component technology called NAND. These high density, low cost capacities from 2 MB to 144 MB. Users of our DiskOnChip 2000 components enable faster read/write speeds, higher capacities and modules will be able to upgrade to the higher capacity chips as better prices than previous generations of Flash components. M-Systems has committed to retaining the same pin-out. This assures that the future higher capacity chips can be installed into our solid state devices.

GO TO SOURCE
When I can't find an obsolete part, I first call GID and they'll come up with my parts every time. Great customer service and follow up as well. Scott emails me from time to time to touch base and see if we're having trouble finding something.....which is often with our 25 yr old equipment.
