Adattatore EPROM 27C322/27C160/27C800/27C400 per programmatore TL866 e T48 Amiga/SEGA
For the 27C400, put the small DPDT switch in non-27C322 mode (to the up) and keep encoder switch positions to 0. Also, because the 27C400 is only 40 pins, and not 42 pins, make sure to put the EPROM with pins 1 and 42 exposed.
