Fluke TK80A

Hi, I'm checking through some of my old stuff and I have a Fluke TK80A, which appears to be a single board computer or training system. It has an 8080 CPU, 1K of RAM (2114), an EPROM and a membrane keypad, some 7-seg LEDs and a few switches. Other than the power connector it has no external connecters or sockets - so I assume it's a standalone system. Some of the LEDs and switches are stamped "ADDR 10000 Output Port" and other addresses that are over 10000 (ie 100F9)- which has me perplexed as the address limit of the 8080 is FFFF and the IO range only goes to FF? I'm going to check it over and apply some power to see what it does (if anything). However, if anyone has heard of this board or know something about it could you please illuminate me to its purpose? river -- No virus found in this outgoing message. Checked by AVG Free Edition.
