It is the responsibility of the company that owns the equipment to maintain their license and software. If they don't have their license and software, they need to buy a new legitimate one to provide. Sure, you can provide it to them, but you need to provide them a legitimate one as well that comes …

I know you feel you've solved the lock-up issue you were having but I wouldn't be surprised if the actual conflict lies with the TF-534 and the GVC card, particularly with the 8MB ram on that card. Please keep me informed as you are one of the few people who are working with a TF534 on an amiga …

but maybe bridging FEAT0 and FEAT1 to ground forces the external clock without software selection or needing other jumpers on the video card FEAT0/1 are outputs from the adapter back to the EGA chip. In another board, it was used to detect the presence of the board by software. The mode change …

Ghetto mounted a new hard drive (Quantum Atlas 10k 9.1GB 68-pin) on long standoffs to my GVP A2000 HC+8 Series II in my Amiga 2000 -- I had to do this because of the 68-to-50 pin adapter I'm using sticks out too far and would run into the GVP's 50-pin SCSI host port. I couldn't find any 50/68-pin …

No, the majority of ESD becomes a latent issue, not an immediate issue. A direct kill shot has to happen on just the right spot, and/or be combined with an already existing manufacturing process defect. At work, I send out dozens of high end circuit boards per year (nuke plant) to be electron …

I'll also note, on my KEA EGAmate-132 that they have the FEAT0 and FEAT1 pins bridged to ground. This is a 132-column adapter (26MHz clock) that came on my Diamond Flower EG-1000 EGA graphics card. I haven't looked a whole lot into the feature connector functionality, but maybe bridging FEAT0 and …

After finding a KEA Systems EGAmate in one of my scrap hauls, I started looking into what it did, and it enables your EGA video card to display 120+ columns for higher text-mode resolution. This is extremely useful for word processing, spreadsheets, databases, etc. Upon my research, I found a PC …

That could have been done, but you'd need more than an ATTiny85 to do it for enough I/O pins. And yes, two 595's are necessary here.

UVC light (which should be in the QUV-T8) works best, in conjunction with Developer 40 ($6 for 16oz). To get the best/quickest whitening results, it should be done this way by using UVC light with the hydrogen peroxide -- it generates hydroxyl. The hydroxyl radical are an oxidizing agent and whiten …

You likely won't find implementation schematics, because those are property of the OEM who designed boards with them and probably still under proprietary release exemptions. Looking at the datasheet, it is actually very detailed and goes into all the necessary voltage requirements, current …

A little better 2-digit design.. easier to implement and program. Less complicated as well. Based on an ATTiny85, so Arduino guys should be able to build and program this easily with minimal cost. Still needs code. Basically the code would be: - read the state of PB0 to see if the PC's turbo LED is …

Transferred my 7700k ITX build into a new Thermaltake Tower 100 Mini case and moved my 1080 Ti to it. (previously a GTX 1080 mini) The new case is way bigger than I thought it would be.

Did you set the dip switches both toward each other for ON, and both away from each other for OFF? I think the resistor needed to be 2k ohms.

You'll have to check behind the SMD resistors as well, because a trace goes behind those and could go to either side or multiple resistors. The connector has a trace behind it too. It would probably be easiest just to desolder the whole thing, document all components/values, scan the board on both …
