SYNOPSIS
       EPROM add-only memory.

       0B [.]XXXXXXXXXXXX[XX][/[ memory | pages/page.[0-63|ALL] | ]]

SPECIAL PROPERTIES
   memory
       read-write, binary
       2048 bytes of memory. Initially all bits are set	 to  1.	 Writing  zero
       permanently alters the memory.

   pages/page.0 ... pages/page.63 pages/page.ALL
       read-write, yes-no
       Memory is split into 64 pages of 32 bytes each.	ALL is an aggregate of
       the pages. Each page is accessed sequentially.

STANDARD PROPERTIES
ALARMS
       None.

DESCRIPTION
   DS2505 DS1985
       The DS2505 (3) is used for write-once incremental  storage.  It's  main
       advantage is for audit trails (i.e. a digital purse).

       The  DS2505-UNW	is one of the UniqueWare class of devices. Some of the
       memory  was  preprogramed  at  the  factory.  See  the  datasheet   for
       specifics. The DS2502 , DS2505 , and DS2506 differ in their function by
       the amount of on-board memory they possess. (The internal protocols are
       slightly different, but the OWFS system handles this automatically.
