Quoted from dung:

Interlock, it takes in 5v and I am guessing the 5v was directed back into the board when it was miswired.

My phone is dead, but I can take one in the morning.

Would appreciate it. Can you also take some pics of the ground wire that leads up to the rail and lockdown bar receiver above the interconnect? I found it was not connected. I have it run like RZ, but RZ stops at that rail, this ground is longer.

Let me know if you need a different angle

No that is perfect. My interlock is a different brand, so its not stock. It was also hooked up wrong. Will wait for spooky to respond to my email on monday.

#1155 20 days ago

There were some early AMH shipped without the interlock wired correctly. Specifically the logic part of the switch (that is read by the boardset) wasn't hooked up.

This is why the game has an option to disable coin door warning - because some games couldn't sense it!

The I/O is buffered with socketed chips to act as a "fuse" to protect the main CPU.

Tried pulling down a copy of the schematic I found online. Was too small to read so not sure which chips you mean. There are 74HCT244 (or so, from memory) above the switch matrix. I did try swapping those in case one was fried, but no dice. It is not a chip I have on hand. There is also a small socketed chip near the plug for the interlock/flippper/coin door switches.

Open to ideas, could order both these chips and see if that does the trick but unsure?

#1157 20 days ago

They are 74HCT244's socketed for the switch matrix. They are the same chips in the RZ version of the boards. Swapped amh's into that just incase there was something frying them in amh. RZ worked fine. Swapped the chips from RZ into AMH, no change in behavior.

The owner spoke up and said that this issue started before he swapped out the interlock switch. The small socketed ic on the amh board near the plug causing issues is for the eprom.

I've posted earlier about my color display project. Using the stock Chroma-Color board, it was limited to 256 colors. I got some motivation, and modified the FPGA and AV firmware to allow indexed color. It's still a 256 color palette, but I can choose that palette for each video scene instead of being limited to a single 256 color palette that was predetermined and locked into the FPGA.

Here are a few samples of the improvement:

I have had people ask, and the biggest hurdle to making this available to other AMH owners is availability of the Chroma-Color boards. Charlie says he only has a couple left, and he's keeping them for RZ warranty claims. I have gotten quotes on the boards, both from Macrofab and the factory that builds LED OCD, but the board is licensed Creative Commons, and I can't resell them unless Parker were to OK it.

The FPGA firmware, I think, is the same situation. The AV firmware was open source at one point, and I'm not even sure what the license is on it. So, in short, it would need a lot of approvals before I could even share the code.

#1159 6 days ago

Looks awesome!!

Maybe put together an "interested" list? I would definitely love to purchase a color upgrade if it were available. There's got to be enough past & future Spooky customers out there to get them motivated to try to make this happen.

#1160 6 days ago

I’ve said it before, but I’m going to have an AMH someday. I’d be interested in this as well at that time.

#1161 6 days ago

herg... Very cool AMH display in color. I really enjoy my AMH. It's a sleeper game, that once I push start, I keep doing it! 1 of 150 it's unique and rare.

I also bought RZLE 1 of 300 (50 with different backglass). I enjoy AMH more tho.

I’d be in on this as well, great job herg

Btw, thanks for the oval post by the bumpers. It’s awesome

It's working well for you? I know I haven't had a single ball trapped there since installing mine, but that's only one machine.

Same, but not sure if I will keep amh. Still need to fix the direct switches before I can play.

I don't think you'll find one much cheaper than this. $5k

I would buy one for sure, even pre-order if necessary.

I know. I keep staring at it, but don't have the funds. I'm out of space (and not convinced I want a 4th location unless they are really close to home) and might start selling games anyway.

If it were only up to me, I'd gladly push forward and make this happen. It's not, though. The original designs are not mine, and I don't have permission to use them to make a batch. Specifically, the board and FPGA code says the design can't be used commercially. Even if I were to coordinate a group buy, it's still a gray area. Unless Parker says it's OK, I'm not going any further than my own machine.

Also, it's not really a "done" project. It works, but I've only colored about 75% of the videos. I got totally burned out doing that part of it. The technical parts, fun. The coloring, not so much.

If you got permission what would the cost be like? The unfinished part is not that big a deal, someone else might be willing to finish it if they don't have to deal with the technical hurdles.

Quoted from dung:

It depends on the quantity. The quote for 25 boards from my normal fabricator was about $70 each plus shipping, etc. If part of the deal was that I use Macrofab, those were a bit more. It would probably have to be in a near kit form, including the display panel and bracket. Charlie (Spooky) sold me the one I have for $250. I also had to change the DMD protector from green to clear and build a power cable.

I would love for it to work out that way.
