Re: How do I properly hook up external LEDs I/O board 5.6 XL?

Yeah that must be a thing with analog boards. Neil on RMC youtube channel was building a desktop mister in a checkmate case and mentioned what sounds like a similar undervolt with an analog io board's led pins. Around 7m50s :) https://youtu.be/JGXZgVLh02Y So the led pins are 5v off and of 1.7v on? I...

Re: Show Us Your MiSTers

Got the classic PC setup Mine's rocking a pc style setup too and and I've got similar logi speakers, but with white trim. Are yours shielded? If they are I might try and get black ones like yours. Mine have to be situated 'just so' to keep my hp7540 monitor happy. I have a few cheap circular MiSTer...

Re: OK. Lines gone, RAM tests good, Amiga still not booting.

Not sure if this is useful, but I used winuae in conjunction with my recently purchased amigaforever roms and installation floppy disk images to create a working a1200 3.1 hd file for minimig. From memory, it wasn't so hard to set up winuae to work with amiga forever files. I might be misrembering, ...

Re: How do I properly hook up external LEDs I/O board 5.6 XL?

Hi, Guzzard. Just wondering which pins you're measuring 1.7v between? Are you measuring the voltage between the 5v pin (pin 1?) and the led signal pins (2, 3 and 4)? Or are you measuring against pin six, which looks like it /might/ be ground on your board according to the schematics? Warning: I'm no...

Re: Rotating vertical games on a CRT with vga scaler - lag?

I'm looking to achieve something similar with my 17 inch vga multiscan monitor: use direct video for most cores, only relying on the scaler when I need to rotate it. I also get the jitters with vsync adjust=2. Additionally, I haven't found a way to apply custom filter scanlines, so I'm relying on th...

Re: Digital IO Board V1.2 to custom LED circuit.

I think the minimig power dim 'issue' might be this!

It sounds an awful lot like what I'm observing.

So maybe no need for rev 0.0.2?

Re: Digital IO Board V1.2 to custom LED circuit.

Thanks for all the pointers! Seems to work with all the cores I've tried so far. The only slight bit of weirdness is the minimig core. When a i run a game via whdload, the led driven by the inverted power signal dims. It comes straight back when i exit the game. Weird. My circuit doesn't put a cap b...

Re: Show Us Your MiSTers

When I ordered my MiSTer I decided that a Digital IO board was perfectly adequate for my needs. "I'll never be one of those fools who gets suckered into falling for all this recent CRT hysteria". So I recently decided that I absolutely must have CRT display for my MiSTer. This popped recently up on ...

So I think I'm there. I summoned up the courage to apply Volt meter probes to the IO' board's led pins. Always terrified of shorting something important. :shock: Documenting what I found for any other noobs who need to know what these pins run at - and have hands as shaky as mine. For future referen...

A hex converter sounded like more fun, but I ordered one before I saw your reply. I ordered a 74hcu04 (cheaper). Should I order a t04 or is the u04 good enough?

Re: Digital IO Board V1.2 to custom LED circuit.

Thanks so much for the help, @legacypixels. Really appreciate it. later... I added power via pins one and six and a red standby led came on. Grounding any of the other pins, sadly, had no affect; so I took a punt on applying 5 volts to one of these. At that point, the corresponding led lit up, so it...

Digital IO Board V1.2 to custom LED circuit.

Hi, I've recently installed my MiSTer inside a re-purposed Bang and Olufsen HDR-2 case. I needed a monitor raiser anyway. :-) The case comes with an LED circuit board which I'm keen to re-use - if I can. I'm wondering if anyone with electronics skills might be able to help me reverse engineer some i...
