I did a bit more detailed comparision by taking I vs V curves using a high-end data acquisition board I had available. The two solid curves are two different original VDRs so in case anyone is looking at this again it's good to know that there is a spread in the curves of the originals if...

Still looking for the control panel only, since I already have a board and I even have a CPO coming so it could have a bad CPO. Trying to avoid attempting to repair the hacked control panel I have.

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

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...

The tester we used during development was an older version of the FPGA cat box that has a thread in the "new products" section. The FPGA cat box doesn't have the A/B tester because it really isn't useful on most boards unless you are trying to make a reproduction pokey. A lot of multi-pokey...

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...

Thanks It has been a big challenge to come up with something that works in multiple games and can be used alongside an Atari pokey in the multi-pokey games. Keeping the cost down while meeting the design objectives is definitely a huge challenge (and Shupac has done a great job with this!)...

Pokey Actually if I was just testing pokeys I would have stuck with yours. The cat box thing was more of a help for fixing boards. Since I had it already and because I needed a testbed for the FPGA pokey I set it up for pokeys (I'm not the main developer of the single pokey, just helping...

Pokey It's fairly complex but it has been done on an FPGA for several projects (like the quad pokey), and I know for sure that a FPGA-single-pokey replacement is possible (and coming soon - not my place to say more). If you want more of an idea of how hard the project is, take a look at the...

Just another check on this. Anyone have a millipede PCB sitting around?

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...
