	The file in this archive makes up firmware version 1.8 for the Zetron 4010/4010R dispatch consoles. To use it, you'll need a 27C256-15 class, or faster, UV EPROM. The file is in Absolute Binary (Data I/O #16) format, with a checksum of 0x71D1.

	Note that, as of the date of this readme, the absolute latest firmware version for the 4010 series
is 1.83. I've been told, by Zetron, that there's pretty much no reason to bother upgrading beyond 1.8 unless something specific to your setup doesn't work. Given the purchase price of $538 for an update, I can see the sense of this.

	The good news is 1.8 is the first version to support use of Zetron's CPSW (Console Programming
software, Windows). Update your console's EPROM with this file, and you won't ever have to use the DOS
version of CPS again.
