I'm starting to distrust WIMA capacitors… I was testing an early 90s TV (which I am currently watching this video on) when it blew…
anybody else getting horizontal lines of interference? Very cool project. My 486 is EISA, must get it out one day.
i whish that these cards exist6ed back in the 90's
I'm so tempted to build one of these for my model 50s! Perhaps one day I'll finally get around to fixing them up.
Sounds great! And super nice work on the build! I’m going to need to do one for my Model 80.
If you use paper towel together with a brush, you don't have to clean it.
Sometimes you get away with a low noise adapter for the Noctua, to make it even less noisy.
Is there corruption in the video sometimes or is my video card going bad?
tubetime is impressive smart guy.
also, i dont think the bake part instruction is very relevant to hand soldering anyways. it is important if ur using solder paste and hot air because if theres too much moisture inside the chip package it can explode when heated as moisture vaporizes.
nice video.
Great vid! What PCB holder are you using?
You made it slightly more difficult than it really is. When programming cplds the standard way to power it for programming is just plug the board or device in and power it normally from the slot or power jack. The chips are designed for in-circuit programming. The 3.3v will go from the 3.3v regulator automatically to the programming header and chip. There's no need to use a bench psu to supply the voltage for jtag programming. If you are concerned about plugging in the board and blowing it up due to a soldering mistake, program with jtag at the beginning…. mount the cpld and regulator then plug it in and program it. Or do what I do….. put only the regulator on the board then plug it in and measure the voltage on the jtag header and the chip vcc pins. If it's 3.3v then mount the cpld, plug the board into the slot and program it in-circuit. Then remove the board and solder the remaining components.
I've not seen PCBs you described at 9:25… My dad used bread boards so that's interesting
I love the Adlib soundboard. It's so enjoyable to hear some soundtrack in Adlib like The Incredible Machine 1 and 2, Monkey Island, Wolfenstein 3D and mostly Wing Commander 1 & 2.
It's a level 3 project as visible on the envelope at 1:42 😅
Is anybody else seeing the visual artifacting ? It's pretty visible @4:58 (middle of screen on the right) though you can see it at other times as well. I've seen it in Green, Red or Blue at various points. I don't get it on any other videos, so I don't think it's just me. ???
The silkscreen descriptions are the best!!!!!
Surely at some point someone will figure out a way to use Modern parts to replace the DAC. It can't possibly be that different to parts being manufactured now The OPL2 for sure needs to be an original part but a dac should not be something that is a problem for a reproduction soundcard
Funnily enough, I've held the original shown in the beginning in my hands. Sadly it doesn't work.
TubeTimesUS is a great person for liberating those near unobtainable cards.
