@scott451 has the only POKEY tester I ever allowed out of my workshop. I was never satisfied with the firmware, which sometimes reports false positives (i.e. working chips test as bad). So if Scott's tester says they're good, they're almost certainly good.) I still have the parts to build a few...

The Quad POKEY is no longer difficult to find. Buy a QPokey v2 from me! $149 + $6 shipping in USA. PM me if you're interested. https://forums.arcade-museum.com/threads/qpokey-v2-now-available-quad-pokey-replacement.526687/#post-4716192

I'm trying to source those little plastic thingies (standoffs? spacers?) that lock themselves into holes in the tray, then you screw the monitor PCB into them. K7000's have these; so does the 15" Electrohome G05 in the Asteroids Deluxe cabaret I'm working on. Any ideas? Has anyone 3D-printed...

I vote for THE GLOB !!!

On the bench: 19" Tovis MTG-1901. I have HV and heater glow but no picture, i.e., no "raster." B+ is steady at 123V. Turning up "screen" on the flyback does nothing; brightness, contrast, and color pots do nothing; screen remains dark. Grounding the collectors of the big neck board transistors...

That Tempest :love:

I am one of those guys who thinks the K4600 gets a bad rap. I like them quite a lot. To my eyes the K4900 and K7000 look a little "soft," like, the focus isn't as sharp as it should be. I rate the 4600 a close second to the G07 as far as image quality. (Yes, the picture on a 20EZ is beautiful...

Following the template provided by OP @CameronMcC: My First game: Gravitar. 1993. Picked it up free, not working, from an ad in the L.A. Recycler. Rented a big-ass F250 pickup and hauled the thing all the way from Ranchos Palos Verdes back to my rathole in Pasadena. I figured, "I'm a grad...

I have a Tempest board that works perfectly in cabinet A. When I put it in cabinet B (a restoration project), it fails to boot. The A/R II board in cabinet B has been tested in cabinet A, where it works fine. All fuses in cabinet B are intact. Confirmed that 5V is present on the board. Pushing...

It's here! https://forums.arcade-museum.com/threads/qpokey-v2-now-available-quad-pokey-replacement.526687/ Of course, after I wrote this, I realized that @jm1607 already ordered one... thanks again JM

I just released version 2 of the QPokey... see thread here

At what price?

That's a good question. This is a chassis I found broken and neglected in a barn. I am pretty sure I never powered it on until I had replaced the caps and fixed the cracked neck board. It does look like the sort of problem where you'd think "Easy, change the caps," except that I already did...

I have a K4900 chassis that looks pretty good except for one thing -- near the left and right edges, vertical lines aren't straight. They're wavy, or "kinked" in the middle. See attached photo. (I adjusted the pic to make the lines stand out; that's why the black background is blue.) It's almost...
