Hello Marion On 07-Aug-00, you wrote: heh -- or built the 6 monitor's Audio and video both source from the 6560 VIC chip: Pin 19 is the sound output, which drives a 2N3904 emitter follower (Q5) through a .1 mfd cap (C16) to pin 3 of the 5 pin DIN connector. Video output is on pin 3 of the 6560. It goes through a 1 meg pot to ground (R7). Wiper goes to 2.2 mfd 10v (C25) to base of PN2222 (Q7) as an emitter follower. R7 sets video level and R32 sets pedestal via CR2. This emitter follower feeds a voltage divider consisting of a 220 and a 270 ohm in series. L1 connects the emitter directly to pin 5 of the DIN connector, and L2 takes a divided signal to pin 4. Either of these should give you composite video. Use a scope and see if the sync and video are there okay. Also check 10mfd (C24) and .1 mfd (C27) bypasses. One more thing to check is the external 14.31818 oscillator and UB9, a 7402. output I think is 7.16 mHz into pins 38 and 39 of the VIC chip. This timing signal is what all sync and color information is derived from. I would bet the emitter followers are shot, or the caps in the circuit have dried up. If it seems the 6560 chip is gone, the computer has gone too -- those chips used to be available from Jameco until they phased them out of inventory. FYI, early VIC-20's had the 5V regulator built into the motherboard with a large heatsink attached -- these had the two prong 9vac input. Later models had the C-64 power supply with an external regulator. These had a DIN power connector on the side. The later version is the desireable one. Also remember that numbering on a 5 pin DIN is goofy -- 1-4-2-5-3 seems to ring a bell. And some had an 8 pin DIN which the 5 pin would plug into with no modifications, identical to a C-64. Look carefully at the numbers in the plastic if you can see that fine print. looked Regards -- Gary Hildebrand Box 6184 St. Joseph, MO 64506-0184 816-662-2612 or ghldbrd(a)ccp.com
