Thanks for the heads up, I just bought it. I've been working on some other electronics repair projects, but this will be a good excuse to get...
We have vacuum desoldering stations at work, I never have much success with them, they get blocked up easily etc. Or maybe I'm just using them...
Yeah that would probably be okay, although it's all a bit of a grey area. I'd be happy to give it away on here, particularly if someone can show a...
I rescued a Sony Trinitron CVM-1370QE from work recently. It's finally allowed me to test an old SL-C30E Betamax player I had (BNC coax outputs)....
Haha I was thinking the same thing, I'm not sure what the top connector is for, someone on here will know. ;)
Hmm no luck, I don't get any h-sync or v-sync on either output connector with the new BIOS. With the old BIOS installed I still get VGA...
Awesome, thanks, I'll give it a go and report back.
Hey, I'm just getting back around to fixing this. I have access to a programmer now, so if you can post the BIOS file sometime that would be...
I normally buy replacement capacitors from LCSC, good for small orders because the postage is less than Digikey/Mouser/element14, they have the...
I finally setup my HP Vectra 286 (model 45945A), which was their first IBM compatible model. I always thought its power supply was broken, but it...
I'm still working on these, I don't seem to be getting video output on either, so I suspect something is broken. I did start a thread on VCFed, so...
Ok, I have got the second NEC APC III out, this ones a dual floppy version. Doesn't have any expansion cards, or a maths co-processor, the CPU is...
Thanks, but I've already got my hands full with these two. I've got a whole stack of broken PCs and monitors to fix. :lol: Some of the NEC...
I'm not sure if it is true CGA graphics, I probed the output connector and got a V-freq of 56.4Hz and H-freq 24.8kHz. The H-freq in particular is...
A broken NEC APC-III has appeared on ebay in VIC. Might have a similar PSU issue to what mine had? Was fixed after replacing capacitors. Comes...
Hey, sorry for the lack of updates, I've gone down a rabbit hole of trying to repair my CGA monitor so I can use it to test the APC IIIs. :lol:...
Yeah that's the one, did you try unplugging and plugging it in again? Sounds silly but probably worth a try, the connection might be a little...
Oh I have some of those! Only two, "Digital Integrated Circuits" and "Electronic Logic Principles 1" both from ~1980. I also have some Australian...
Oh yeah, I think that's worth doing too. But I guess there's a risk in spending money on it if it can't be fixed. Should be pretty cheap to get...
If your multimeter has a low impedance mode (LoZ) you can use that to discharge capacitors. Using a screwdriver can damage the capacitor because...
