Help identify these front panels

I just got a couple of unidentified front panels. If anyone can shed some light on what computers these come from, please let me know! Front Panel #1: - No bezel - Has flat switches exactly like the Imsai except they're all black - In the upper right there's a 16-key hexadecimal keypad; black keys with white lettering. - Two rows of switches; 7 in the upper left, and a row of 18 below. - There are numerous LEDs arranged mostly in banks of 4 with 7545 TTL drivers. - The LEDs are on a riser card about 1/2" off the main front panel card. The main card is dark gray and the LED card is green. - Three 40-pin ribbon cable connectors on the bottom edge. Front Panel #2: - Very simple design with metal bezel. Looks like it's from a mini. - 20 cup-shaped plastic paddle switches, some navy blue, some sky blue in color. - Switches are labeled "CLR, STP, MRD, MWR, ADR, EXE" and numbers 2 through 15. - Three lights in the upper left are labeled "POWER, WAIT, CARRY, ENABLE" - There's a key lock in the lower right - A bundle of cables trail from the panel terminating in two 46-pin connectors and a few power leads. - An ink stamp on the PCB reads "5172" - 5/1/72 perhaps? thanks all! By the way, if someone needs one of these, let me know! Kai
