SSD0 replaced with an EPROM/OTPROM
1. Follow steps one through three in the SSD0 replaced with a flash device
section and use a 512K flash.
2. Power off the PC-510 and remove the flash from socket U13.
3. Use an off-card programmer to program a 512K EPROM/OTPROM.
Use the flash as the master copy.
4. Insert the programmed EPROM/OTPROM into socket U13.
5. Remove jumper W2[7-8] for EPROM USE.
6. Power on the PC-510.
7. The new SSD0 device is now ready to be used as a bootable, read-only
DOS drive.

SSD1
Generally, SSD1 is meant for storing the application programs to be
executed on powerup. The programs are automatically loaded into DOS
memory and executed. The standard version of the PC-510 comes with
a 2 MB flash soldered on-board, while the optional version contains a
1 MB flash soldered on-board. Your application programs can be saved
to flash using the PICO FA driver which makes the flash device a read/
write disk on your PC-510. Saving your programs onto the read/write
disk allows you to do this up to 100,000 times, allowing updates to your
application programs. These devices are erased automatically during
the programming process.
SSD1 can be accessed directly as a read/write DOS drive with the PICO
FA driver. Also, it can be accessed directly as a read/write DOS drive
when the PICOFA.SYS driver is loaded. While this is convenient for
product development, the flash, however, has a limited number of writes
allowed. Therefore, Octagon does not recommend SSD1 be used as a
data logging device. Refer to the Software utilities appendix for infor-
mation on supported flash devices and a description of PICO FA.

DRAM
The standard version of the PC-510 is shipped with 1 MB of DRAM
on-card. The PC-510 can also be configured with either 4 or 16 MB of
surface mounted DRAM. The on-card DRAM socket holds up to a
16 MB dual in-line memory module (DIMM). The card supports fast
page mode (FPM) or extended data out (EDO) types of memory. These
