If you look at the schematics on funet, http://www.funet.fi/pub/cbm/schematics/computers/pet/univ2/ you'll see that the empty sockets are for ROMs: Socket Function Type Address UA3 Characters 2316 or 2332 N/A UD7 Editor 2316 E000-E7FF UD11 Expansion 2 2332 A000-AFFF UD12 Expansion 1 2332 9000-9FFF Funet has the necessary ROM images: UA3: http://www.funet.fi/pub/cbm/firmware/computers/pet/characters-2.901447-10.bin UD7: http://www.funet.fi/pub/cbm/firmware/computers/pet/edit-4-80-b-50Hz.901474-04.bin http://www.funet.fi/pub/cbm/firmware/computers/pet/edit-4-80-b-50Hz.901474-04-3681.bin http://www.funet.fi/pub/cbm/firmware/computers/pet/edit-4-80-b-50Hz.901474-04%3f.bin Nope, don't know which one's the best :) These are all for 50 Hz machines and you're in the UK aren't you? -- ___ . . . . . + . . o _|___|_ + . + . + . .
