I'm pleased to announce that I've worked with @p0rchio to assume web hosting for JAMMArcade.net - the site will live on! I'll also taking over as "editor-in-chief", so if anyone wants to contribute retro console, computer or arcade repair write ups, hit me up!
I was feeling pretty good about repairing this Guwange #arcade board that had lines through the sprites. After reflowing the 013 custom, line buffer RAM chips, and sprite ROMs, it was looking clean. But … there’s still an addressing issue with some background tiles! 😑
Here’s another update on this faulty Namco System 2 board - this time with far too many details on diagnosing TTL logic parts and a bit of ROM hacking.

More light reading for arcade repair fans!
In-progress report on a Namco System 2 where 11 games run perfectly, but 3 hang at startup. Isolated the fault to the Video board, ruled out socketed chips, and spent way too much time chasing a GAL red herring!

Well, the CV1000 blitter was definitely measured extensively.

Repaired a Cave CV1000 #arcade board with faulty color amps, resulting in a dim picture with a yellow tinge. Thankfully, the amps are off-the-shelf parts, and one swap later, now the image is bright, colorful and tinge-free. Detailed write up at jammarcade.net/cave-cv1000-b…
<sigh> It’s so aggravating when a microscopic leg randomly snaps off of a TSOP-48 SMD flash chip when soldering it to a board. Fortunately I have a spare handy but it takes hours to flash with my current NAND programmer. 😅
I fixed up an Arika Fighting Layer #arcade board running on Namco System 12 hardware this weekend. It started up with a scary FIRST POWER ON DATA ERROR message, but replacing the RTC chip sorted it out. Full writeup at jammarcade.net/fighting-laye…
Just in time for #marchintosh, this PowerBook 1400cs was just gifted to me. Featuring a 233 MHz PowerPC CPU, 64 MB RAM, 800 MB hard drive, Zip 100 drive, and 28.8k baud modem, this time capsule is in really nice shape! Now I need to figure out how to load some games onto it. 😎
A CPS3 #arcade cart came in for service after suiciding due to a dead battery. It wouldn’t work after flashing the Darksoft UltraBIOS. I noticed missing solder next to the clock crystal, so I addressed that and now the cart works great! I wish all repairs went this smoothly. 😁
I finally sorted out the remaining issues with the sound on this Golden Axe 2 Revenge of Death Adder #arcade board. Detailed writeup at jammarcade.net/golden-axe-ii…
I helped a friend calibrate his Sony KV-36FV16 CRT today. The greypoint range dialed in nicely except for a tiny blip in the 0-10% IRE that barely matters. The geometry is also surprisingly good for a flat screen Sony!

@_ShootTheCore just published a writeup on reviving a Seibu Kaihatsu SPI mainboard with a corrupted region code, and resolving jailbar corruption with the graphics with a Raiden Fighters 2 cartridge. #arcade #shmup

A busy evening tonight repairing both a Seibu Kaihatsu SPI #arcade board and Raiden Fighters 2 cart. SPI Revive by Trap15 brought the SPI board back, and reflowing the solder on several SMD ROMs fixed the jailbar graphic corruption in RF2.
I thought I was done with this Sega System 32 #arcade board but playtesting revealed that it would still freeze up periodically. It seems that another TTL clock buffer just to the left of the one I just replaced is bad as well - I even cross-tested it with two testers to be sure.
I got a dead Sega System 32 #arcade board up and running again yesterday. Culprit was a dead TTL clock buffer chip. Full writeup on the diagnosis coming soon.
