Microgenic EPROM Programmer
EPROM Programmer from Microgenic Systems.
Reportedly requires a 15 volt AC power supply which plugs into the socket located at the top right hand corner of the board (not confirmed / no warranty).
Uses a NEC uPD71055 chip, which seems to be an (exact?) clone of the more common 8255 PPI chip. The (blank) EPROMs are to be inserted in the 28pin Textool socket (located at the upper edge of the board).
