maximus, you're totally preaching to the converted. :lol: When you say "used up CRTs", are you sure that the tubes are what's going bad? Perhaps these monitors could benefit from a re-capping? The reason say this is because I have seen repairs of many 50+ year old CRTs that still test strong. Do …

used 20 year old CRT-EGA-Monitors are sometimes more expensive, More than US$400~500? That's what these modern LCD replacements tend to go for, since they are sold as industrial equipment for a captive market. And they look like the typical Chinese mediocre build quality runs through them. You can …

I apologise if you have tried this already but if you imaged the drive first could you not restore the image which would also change back the dma setting? At least then you could get back into it :) Thing is, in order to get at the hard drive I have to remove: Bezel Digitizer LCD Inverter Battery …

I'm not from Brazil, but I know they pay excruciatingly high import duties for pretty much anything, so I can understand why he's trying to salvage that one. Personally I'd go 10µF 16V all over it and test.

On my retro rigs I tend to put storage & communication controllers on the top and video & sound on the bottom, the latter as separate as possible to minimize EM noise and maximize airflow. I like the 'every-other-slot' approach when conditions allow, just because it gives me more room to manipulate …

Teardown began on a Hitachi 21" fixed resolution CRT. As you can see it needs at least a recap. It will take several weeks for the parts to come in. Hey! I probably had the same monitor on my desk like a decade ago, just with different branding: https://133fsb.files.wordpress.com/2015/10/dscn8721. …

My guess is that keropi wants to improve airflow (and maybe weight), and since residential customers aren't charged extra for bad power factor by the energy companies, removal of the coil won't make a difference on his monthly electric bill.

That 6V output is probably for powering a set of external speakers without a wall-wart.

I've had cases with curved fronts but straight covers so one thing doesn't necessarily imply the other. The most important thing is that they actually fit. You can always chock it full of drives if you can't find appropriate blanks. 😜

I rarely use the front USB ports on my case, but I got concerned enough to check with a multimeter and fortunately there's already a direct path from connector shields to case ground. I've always assumed that the connector shields were ground-referenced, but seeing that's not always the case I'll …

I haven't come across anything that uses the 3.3V line on the SATA power connectors (yet), normal Molex to SATA adapters have worked just fine with anything I've thrown at them. I suppose it's some sort of catch-22, since having the 3.3V isn't guaranteed, manufacturers are going to be reluctant to …
