Well, here are the specifics: 1) The computer in question is a Sam Coupe (koo-PAY) clone. 2) I wanted to use PS/2, but USB may work. 3) I would like to have an Atmega chip act an an interpreter. My idea is to have the Atmega scan for the standard PS/2 keycodes and inject the corresponding key...

I'm working on making a Sam Coupe ATX clone and I need help figuring out a way to use a PS/2 keyboard with it. I did find a device that would do what I want, but it's for sale only on a questionable website. The original Sam Coupe keyboard was a passive 8x8 matrix, if that helps. I can...

I have OS9 installed on my Quicksilver, so I might be good to go for the flash utility. I didn't want to mess with OSX on a Quicksilver G4, but this may be the one thing that makes the choice for me. I currently don't have a G5 machine on hand, but *if* I wait until VCFMW 2023 and show up...

Thank you @luminescentsimian. I will try that!

Context: I have flashed ROMs in the past on various cards and motherboards in the PC world in the past. I'm wanting to flash the ROM on an Adaptec 39160 PCI-X card and use it permanently in my Quicksilver G4 tower. For clarification, this is a 64-bit PCI card, not PCIe, PCI-e, or anywhere...

I recently got a Power Mac G4 Quicksilver and I was wondering if a video card from a G5 Cheese Grater would work in it. I've found versions that seem like they would work being that they have a normal 8x AGP card edge except for an extra card edge bit towards the monitor connector end of the...

What uses the 25v rail in a Power Mac G5 tower? Just a question for futureproofing, nothing more.

I definitely has less than 30 pins. more like 20

Exactly. Single Inline Pin Package.

It's a SIPP THT part.

I just looked and there is nothing but black on the back. No printing or any marks.

I'm looking for information as to what this is. The "all-knowing" Google is stumped. This is part of the LCD circuitry for my Zenith SuperSlim 286 laptop. That's all that I can figure. The reason why I want to even mess with it is due to the corrosion on the underside of the motherboard on...

Thank you for replying, Kai. I did start playing around with TinkerCAD and I did get something that might work with help from Joe of Joe's Computer Museum. At this point, I have a keyboard of my own but I do not have a 3D printer. That's what I really need now, I guess. I have been trying...

Hello all! I have embarked on a task to remake the Tandy 1000 keyboard's PCB. Here's my plan: 1) Create the PCB in KiCad (I have it mostly done at this point) 2) Send the gerbers off for manufacturing. 3) Buy enough Cherry MX switches to assemble a few keyboard PCBs. 4) 3d print adapters...

Just a shot in the dark, but with the audio equipment that you have on hand for producing video content, you might be able to compare the sound waves emitted from the "dead" CC and compare that to your healthy CC. This is just a blind shot in the dark hunch based on my kids' reaction to any CRT...
