While I am mainly interested in the 5152, I may also be interested in some models I am less familiar with. I just got an interest in dot matrix printing and would like to be able to print things from my PC and other old machines.

I have a few CRTs which range in severity when it comes to emitting that nice 15kHz screech- from my awesome Samsung Syncmaster 900SL which will only make an audible noise when feeding in jank signals (it is mostly quiet), to my Toshiba 14AF42 TV which makes a pretty audible and annoying noise...

This feels like a weird question to ask, but when using the multiplier jumpers on a board to switch between ex. 25, 33, 40, and 50MHz, what is actually generating this base clock? Do the jumpers control an external clock (such as the 14.31818MHz crystal I see nearby on the board) or does the...

I finally got my 486 together and working and decided to test out DOOM... It runs and sounds great... for what I can actually hear. Sound effects from the game work just fine, yet for some reason it isn't playing any of the music through the FM chip. I also cannot get it to play no matter what...

I have an IBM 5153 that I would like to do more with and it is much more portable than the other CRTs I own. While I have converted CGA to VGA before, I haven't really ever seen anything that goes the other way around, except for one sketchy looking adapter that claims to go from VGA to CGA, yet...

I have been debating asking this here because the hardware in question is a piece of late 80s music gear, but the thing is pretty similar to early 80s computers in some aspects. If there is anyone on the internet who can answer this, I am pretty sure it would be someone on VCFED. 🤓 Anyways...

I recently picked up a Chaintech 486SOM board that after having a capacitor blow, now needs a new BIOS chip as I am getting this following error: Award BootBlock Bios v1.0 Copyright (c) 1995, Award Software, Inc. BIOS ROM checksum error Detecting floppy drive A media... INSERT SYSTEM DISK AND...

I just finally got my 486 system together, and after fiddling around and finding out that it's only showing video with an ISA video card, I am hit with this following unpassable screen: Award BootBlock Bios v1.0 Copyright (c) 1995, Award Software, Inc. BIOS ROM checksum error Detecting floppy...

This is a weird one. I recently picked up a Quantum Q2040 for cheap and it looks to be in pretty good condition... except for when I shine a flashlight on the top platter, I see that there is scattered debris that appears to be plastic "dust" sitting on it. I would assume that this is from the...

I just bought an 486 case and thought it would have a 7-segment turbo display, but the spot for it is blank and is able to accept a new one should I be able to get one. Maybe I just wasn't searching the right terms, but I am seemingly unable to find a spare display that I could stick in the...

I am currently looking to buy an AT case for a 486 system that has a lot of 5.25" expansion bays, as I want to build a system with a bunch of wacky accessories in the front or plainly load the thing up with tons of floppy drives. After looking through eBay, LetsGo, Craigslist, and...

I recently picked up a pristine 5153 monitor for my PC. In my infinite wisdom though, I peeled off the plastic film on it (which had turned ugly and bubbled over the years) and scratched through the red, green, and blue paint, while the rest came out fine. What are my options? Is there anywhere...
