After making some high score saves boards for the dedicated Sega cabinets, I figured I would try to "complete" the vector labs multigame to add the high score saving that was originally planned. I added an FRAM to the nvram spot on the board, FM16W08-SG, plus a 0.1uF cap for it's decoupling...

After fighting with fixing the stock AC motor for the beacons on my F14 Tomcat (not a fan of the motor design), I made an adapter to use a $15 DC geared motor (24V 100RPM, offset output shaft) from Amazon. You need to use a bridge rectifier to rectify the AC into DC. I also added a 5W 50 ohm...

Looking for a system11A board that has minimal battery damage to get going for my F14 pinball. Not working or untested is OK as long as it is in OK physical shape.

Another "making room" sale - this dig dug has water damage on the bottom (mostly the bottom front and bottom right) but the rest of the cabinet is solid. Also it looks like someone installed some kind of bar on the side so there are a couple of small holes in the one side of the cabinet. Game...

I've got to make some room so I'm selling my missile command. It's got the Braze multigame/HSS kit and the trackball has been rebuilt with new rollers and bearings. Cabinet is in good condition with no water damage but there are some scratches and other damage on the side art (see pictures)...

Red Baron original aux board and converted battlezone-style main board. The modification for the RB rom has been made on the bottom rather than the “stock” way of lifting a pin and using a wire on top. These have been running for a few years in my converted cab and have been reliable. 400...

Anyone have a gravitar control panel? Empty or populated is fine, just hopefully without extra holes drilled etc. Thanks Fred

I need to make some room and fund some projects. Anybody near Nashville TN interested in my Red Baron "hack"? It's got a 19V2000 monitor (recent cap kit and transistors) - like many of these I've seen the tube is a bit on the dim side but it works fine. Original Aux board and the main board...

Here's one of my spare space duel PCBs I'm selling to fund some projects. - It has been tested for a few days on the bench and in my cabinet. It's one of my better ones - no major repairs on the board and the edge connectors are clean, etc. ROMS have the better type of factory sockets. I...

Price lowered to 350 to get this sold... - I've got multiple spare boards for a few of my games so it's time to sell a few to fund some upcoming projects. I've tested this for several days on the bench and then in my cabinet. As you can see in the pictures there are some machine pin sockets...

I'm looking for a set of side art for a major havoc tempest conversion from TOG or elsewhere. Or does anyone have artwork files or a scan of the original major havoc tempest conversion side art? I might just use black laminate (or white in case I ever convert the cabinet back to tempest?) but I...

Has anyone done a memory test on pole position through the Z80 socket using a Fluke or similar? I'm working on the FPGA "cat box" tester Z80 interface and I've been fighting with getting all the PP RAMs to test through the Z80. The rams in the region 4800-57FF seem like I can write them through...

I've been working on Z80 testing for my FPGA tester and I came across this issue when working with Donkey Kong Junior. I also remember it being an issue when I tried a "standard" arcade switching power supply in the cabinet when my real one went out. Back then I put back a "real" nintendo...

Anyone have an "empty" space duel cabinet somewhere near Nashville TN? I need a control panel, but I'm trying to get one fairly empty so that I can keep the cost down and since I already have a wiring harness, working PCB, and power brick and I can build a 6100 monitor like I did for my Tempest...

I typically use an old analog oscilloscope for troubleshooting XY games on the bench and I have tested out several digital oscilloscopes (Tektronix, Rigol, and old HP) but nothing has been very useful in XY mode. I have a new Keysight DSOX1102 that is actually quite good (maybe not as good as...

I'm part of a group working on a single pokey FPGA replacement for Atari arcade boards (which is hopefully coming soon - we're making rapid progress). I could really use a millipede board that I could fix up to do some testing, since millipede has a "unique" way of connecting the pokey audio...

I'm looking for a battlezone full size upright cabinet - I have most everything except for the main cabinet (wood parts and coin door), the mirror, the cardboard bezel, and the color films for the monitor. I have all the electronics, wiring harness, control panel, blacklight / light assembly...
