We fixed boards, tested stuff, worked on all kinds of fun things! Pat arrived at 9:30 to help by bringing 2 extra chairs and his JAMMA test bench and the last person just left a few minutes ago - about 15 hours and I'm beat.
I grilled up some smoked venison sausages, jalapeno and cheese venison sausages, and some pecan smoked sausages. I mixed up some garlic and pepper smoked salmon with cream cheese to spread on some toasted baguette slices. There was a veggie plate with 4 colors of bell peppers, celery, carrots, and broccoli. My son mixed up the ranch dip (sour cream and ranch packets) for the veggies. There were chips, 3 salsas (mild, habanero, and ghost pepper), 3 types of cookies, some Twizzler bites, and 2 types of ice cream sandwiches.
Folks brought beer and some extra sodas. We went through 7 bags of ice today keeping everything cold. I had the soda machine almost full and the antique washing machine on the back patio was full of drinks. I had the game room powered up and we had all 3 workbenches going at once.
I never did go through the presentation! I'm still working on some of it but there was just too much to do.
I'm wiped out. It was fun and we'll do it again in the fall.

We had one KLOV member that flew down from Nebraska to attend!
Yeah, that 2 slot board was a bitch. The Color RAM Error from hell! Replaced the color RAM, the NEO-G0, the 74LS273 chips, and reflowed the NEO-B0. Found that if I touched one pin on the B0 with the logic probe the junk graphics on the screen changed. AH-HA! Grabbed an MV4 from the scrap pile and followed the trace. It went to the CPU, pin 51. Followed the trace with the continuity check on my mulitmeter and found it stopped under the CPU. Pulled the CPU, cleaned the gunk under it, reinstalled it, and patched one trace.
Now it gave a Z80 error. D0 data line was stuck low. Swapped Z80. Pulled the Sound ROM and found it had a good checksum. Swapped the sound RAM. Under the sound ROM was a bit of corrosion. Cleaned the corrosion mess and found a damaged trace. Reinstalled the sound ROM, patched the trace, and the board booted up and played games nicely.
It was a bitch.
So was the UMK3 board I repaired for CEC_DFW (David)... A banned forum member sold him (and had failed trades with other members that led to the banning) a "working 100% UMK3" board with a burnt component that wouldn't boot. Patched around a fried coil and circuit board char powering a 74ABT245 to the CPU to get a game board that would randomly boot/not boot/crash. Reflowed the DMA Controller and Orbit chips. Board tried to boot but had RAM errors, graphic corruption, and crashes. Searched and searched. In the meantime, the board booted to WWF and NOT UMK3! Swapped the ROMs and the security chip out with chips from a parts board David bought. Then noticed that the 74ABT244 buffer chip to the CPU wasn't getting power! Replaced an open surface mount coil and the game booted. It had a slight graphic corruption issue that was solved by swapping out one of the custom socketed PLCC ICs.
Those were the 2 big bitches of the day! And a first for me in that I've NEVER seen a chip partially working with NO power being applied to the power pin!
I was the self appointed grillmaster and we had all three workbenches going at once.
