About L403 and DL1 : I made custom symbols to match the pins written on the schematics.\n\nFor DL1 : \n\nI compared with the schematics of the Atari MegaSTe rev C and of the Falcon030. Pin 12 appears grounded on the former ; on the later, pin 9, 10 and 12 appears grounded, \nwith pin 10 taking the central position, while pin 3 and 6 are bridged together. \n\nIn the gerber of the sparrow (found as 'Falcon Gerber' on the Atari Document Archive site), pin 2 and 7 are wired as expected in the schematics, and the pin 3 and 6 are bridged \nlike on the schematics of the Falcon. The pins 9, 10, 12 seems bridged with a fine line (1 mil width).\n\nIn the end, I create a symbol with all the pin, and marked to not connect pins that are not of the STe schematics.\n\nI created the footprint of L403 and DL1 after the gerber.\n\nI wish you good luck if you need to replace those components or remake this part of the pcb !\n

Change values for PAL (I took them from the Falcon030 service manual\nafter checking that this part of the schematics is the same as the\nSTe - lucky me)\n\n* C421 : 100pF\n* DL1  : 4.43MHz\n* L403 : 14uH\n* R451 : 22\n* R456 : 1K8 (PAL-I) ; 2K7 (PAL-B)\n* R463 : 1K2\n\nDid you know there was several PAL variant ? \n* PAL-I is for UK/Ireland\n* PAL-B is for Western Europe, Australia and New Zealand
