You could test each of the keyboard plug pins with a multimeter to see if there is connectivity to the solder points on the back of the pcb to rule out a faulty plug

I got stuck on the same error with a 486 board a while ago, still stuck there. On the board I was working on the cmos memory is embedded into a qfc chip. Naturally I assumed it went corrupt and replaced the qfc chip but still same issue. There is not much info about this error but form my research …
Re: Cache woes. Is it Faulty or is it the Motherboard being spastic?
Posted on 2020-11-27, 00:27
It could be a line form cache or memory losing connectivity, signal is lost sometimes and not others. If you had a external programmer like a tl866 you could check the cache chips direct and rule them out

You can usually tell by putting original battery and suspected battery side by side. See if the fonts and quality of the print is the same, cheap Chinese fakes usually have more blurry and less sharp writing, might be crooked and might even have spelling mistakes
Re: How Do I Remove These Big Blobs of Solder?
Posted on 2020-11-22, 03:55
Indeed. no lead solder is a bitch too. Gave me trouble at first in microsoldering (this is this thing you repair through sharp tweezers and microscope level for phone repair), took me long learning curve to get hang of it while I'm religiously using leaded solder and even reballed the chips and …

I have a V2 and I damaged it years ago trying to desolder the rtc. Right in the same area and qfc chip. The Floppy never worked and I never pieced it that its from the damage in that area. I never really looked far into it since all my floppy disks are now unreadable and the only thing the floppy is …
Re: Any street rod 2 experts here?

Yeah I am not sure what its supposed to be, wet cement or gravel are probably the only 2 things that come to mind. I think this is the only reason i keep playing this game because this cement/gravel has always been such a hard obstacle. Its a challenge that keeps calling you back. Slowing down to …

Any street rod 2 experts here?
Posted on 2020-10-20, 07:44
This is one of my all time favourite games and I still play it since it was made. Was wondering if anybody here can enlighten me on a few items which I could never get more speed or noticeable performance from: 1. Change stock muffler to glass pack muffler (since its a $15 item I am guessing its …

When I scraped the paint and corrosion off the top I was really surprised how much copper was left ! I had assumed that the trace was completely gone, but it looks like there's enough of it left that it might work. There are still some dark spots left (I think it's just a stain on the copper) that …

I was looking at the theory how the signal gets to cmos. So it goes cpu - > north bridge - > south bridge - > cmos/bios (possibly through some invertors and buffers) I started looking very closely at both chipsets (north and south bridges) I noticed some green corrosion which camouflaged with the …

I removed the keyboard connector, everything has right continuity and resistance under it. Checked voltages on the cmos chip, vcc pins have 5v. Also checked vcc on the chipset also has 5v vcc pins I need to inspect really good under the ram slots and keyboard controller again incase I missed some …

yeah those overdrive cpus get very hot from my own experience, the heatsink is pretty small. Maybe for word-processing it is ok but I find that playing a highly demanding game like duke3d those over drives get too hot to touch. I would attach a fan, I never kept one in my system long term so didn't …
