EPROMs

The mainboard contains three EPROMS: U32 (2764), U63 (27128A) - character generator and U93 (27128A). If this terminal follows the previous ones in the TDV 2200-series, one EPROM contains the emulator, while the rest (one or two) contains primitives. For this terminal it is unknown which of U32 and U93 is emulator / primitives. Dumps are available. sebras has made a python script to extract the font from the character generator dump and convert it to an image, see sebras/norsk-data-vdu-301-s on Github.
