This one could be a standalone 8085-based computer with Cherry-MX keyboard on board, 12 5x7 LED matrices and 6 7-segment indicators with some additional indication and stereo-audio output (2 channels with 4 bit per channel):

Intended to resemble look of Elektronika MK-85 and CASIO FX-700P (also known as CASIO PB-100 or "RadioShack TRS-80 pocket computer"), but my board is slightly bigger (14x6") and it has more PC-like keyboard layout to make it looks like a real computer with optional backlight :)

P.S. There is a possibility to make a true Elektronika MK-85 clone from it with help of additional board with PDP-11 compatible Soviet processor 1801VM2 (still available on ebay) with original firmware (MK-85 was PDP-11 compatible pocket computer produced from 1986 to 2000 that run BASIC interpreter similar to CASIO FX-700P)...
