Very surprised i havent seen this one mine before. I have this on a bunch. Some example: Over Top is fake label I think, but has holes through it so _might_ be a conversion. The others are not drilled.

Multiboiz

That looks like a really good way to blind yourself

I also think that the laser doesn't seem super useful for cutting due to the limited space, and as mentioned probably issues with acrylic... but it might be sortof useful for engraving which needs a lot less cleanup, so not completely useless. The bigger bed and dual nozzles are cool, but I'm...

Realized that I've not written in this thread before, but I've bought from @sheep_nova several times, and just did so again this week. Always a great experience. Buy with confidence

Thats pretty cool. Looks like something that would be great for scsi boot on Fm Towns computers too.

Uh on what exactly? :) I didn't really find any good old logic analyzer outputs for this last i checked, and I'm too lazy to start logic analyzing cv1k boards so not really.

Pretty sure thats Seimitsu JB-35T. Also used in some jong panels for cabs. They are no longer produced.

And Ibara wont run CV1k-D games

I need to fix my hosting again, but an old archive link without pictures of my old site has both the info for MVS and JVS: https://web.archive.org/web/20240414014103/http://arcademahjong.com/hardware.htm

Yeah I can confirm Deka 2 will absolutely not boot in my Astro City with a (recapped) stock power supply. These boards need a lot of power.

Iirc all boards on the early psikyo hardware that strikers 1945 and tengai are on have that timing. The later hardware that strikers ii and so on uses have other timings

That feels more like fear mongering. Don't get me wrong I think it's a dumb idea to shut out third party slicers, but a lot of the other speculation is just silly.

Im confused, are there some new filament limitations or what

kindof doubt that people do work on much smaller pitch than tsop48 which has 0.5mm pitch tbh. What modern ics have smaller pitch than that? Maybe some tqfp with extremely tight pitch has slightly tighter but dunno. Yeah its doable by skilled people but lets not exaggerate here either

Actually maybe its possible to get pixel clock by just looking at the DAC, and scoping when it latches color signals to outputs? Should be a pin for that probably. Have not looked at datasheet. That would make things fairly trivial.

I guess you can probe the digital color signals that goes into the DAC instead to not have to deal with analog signals though. That should make it easier to use cheaper tools

As an example from when I did this for old Psikyo boards: Dot clock 7.15905 MHz Total: 456 dots Visible: 320 dots Sync: 50 dots (~11% of 456) For looking at color value you need analog signal support. I dont think those cheap chinese ones are a good match for this. There probably are cheaper...

Ok, so this is my understanding of how you would measure this, but I am NOT an expert in this so feel free to fact check me. For a aproximately 15khz game, running at about 60hz you can assume that aproximately 250 horizontal lines (hsync pulses) will be generated per frame. Games will not run...

Yeah, I sold all my D boards but in my old pics my Akai Katana had a IS42S32400D-6TL http://cave.buffis.com/pcbs/ak.jpg
