SSD0
A 32-pin DIP socket accepts either a 5V flash, SRAM, or 512 KB/1 MB
EPROM. To use an optional 512 KB SRAM, the PC-510 requires a
factory change. The socket exhibits high retention force and affords a
gas tight contact. SSD0 optionally contains the BIOS drive and ROM-
DOS 6.22 in ROM. By default, the optional SSD0 reserves 192 KB for
BIOS and 320 KB for a drive area. Flash file system software is in-
cluded which allows the SSDs to emulate hard disk operation. SSD0
options include:
n
SSD0 socket installed standard
n SSD0 socket not installed optional
n
SSD0 socket/EPROM installed optional
n SSD0 support from SRAM optional
For information on changing the device type, refer to the W5 SSD0
table in the Quick start chapter. You can also install compatible
PROMs into SSD0 through the supplied utility programs found on the
PC-510 utility disk. You can format the flash or SRAM while in the
socket. EPROM usage, however, requires off-card programming from
either a master flash or a master SRAM.
SSD1
SSD1 is used for storage of the applications program. A standard 2 MB
5V flash is soldered on-card. The flash programmer is built-in which
allows on-card programming of the device. The PC-510 includes flash
file system software, which permits the SSDs to emulate hard disk
operation. Automatic “wear leveling” ensures that no single section of a
chip will reach its life span (100,000 times), while other sections will
scarcely be used. A 1 MB device reserves 192 KB for BIOS and 832 KB
for a drive area, a 2 MB device reserves 192 KB for BIOS and 1856 KB
for a drive area.
