	This archive contains EPROM image files for the Data I/O Unisite firmware (EPROM) release version 1.3. This is the last and latest known for the Unisite, and it fully supports the MSM (Mass Storage Module) option. You will need a pair of 27C256-class EPROMs to load it into. The file checksum-16 values are 0x04BA for the LOW byte device, and 0xD59E for the high-byte.

	Keep in mind that the Unisite requires 8MB of RAM installed to support the MSM, as well as this firmware. The revision code on the mainboard should be 701-2313-002 or later (visually distinguished by the presence of two 30-pin SIMM sockets near the expansion connector). Also, Data I/O pulled a nasty in that you will need a specific PAL, DIO part number 324-1852-002, in the U91 socket to support the required pair of 4MB x 9 SIMMs.

	You should be able to download the code for this PAL (it has been successfully reverse-engineered) from either the file area of the Yahoo Data I/O group, or the Blue Feather Technologies FTP site at ftp.bluefeathertech.com.

	Happy tweaking.
