Oh man, Chinny, I like character as much as the next guy, but this gremlin is a little too much to put up with. Thanks for the reminder regarding the battery. I'll keep an eye on it. I plan to replace it with an external battery once I get the rest of the system stable.

Thanks canthearu. I'll get some contact cleaner and give it a good once-over. I've also ordered a replacement PSU in case that's the culprit. There are no electrolytic capacitors on this board. I think they're all tantalum. I've attached a picture of the board below. If neither of those things work, …

Hi folks. My 486DX2/66 build is only posting intermittently. I would appreciate any advice, since this is my first retro build. Happy to provide info and pics re components, too, if it'll help. I'm using a SOYO SY-25N mobo and a 486 DX2/66. When powered on, the power supply fan always starts and the …

I'll give that a try. Yes, I have an external USB floppy drive for my Mac. One thing I want to understand is how the floppy signals to the computer that it's bootable. Is it just a function of what files are on the disk or is there something written to a hidden part of the disk? And as such, can I …

Can I create a bootable DOS disk using my modern Mac? If so, how? I'm building a retro 486 and would like to be able to create bootable DOS 6.22 install disks. I've downloaded the install disk images from a repository online. Do I just need to unzip them and copy over the files to a floppy or do the …

Thanks, Pentiumspeed. I hadn't see that first resource. I've already started the return process on eBay and there is currently another unit for sale that seems to be in better condition, so I may just proceed down that route. But I'll post the outcome here if I decide to keep it and get it fixed. …

Thanks, pentiumspeed. The problem does persist when it's not connected to the main box, so I believe it's one of the circuits in the monitor. Good suggestion about finding a repair shop. I already spoke to someone that may be able to help. I may also just return it to the seller, if I can. Thanks …

Hi! So, as part of my journey into retro computing I bought an IBM PS/1 2011 off eBay. This was the first PC my family owned, so I thought it would be a great place to start a possible collection. Maybe not, it seems. Though it was tested as working by the seller, powering on and booting up …

Tricky. If you 'process' lots of motherboards you end up with piles of this stuff for almost nothing. I guess lots of people have that stuff - I certainly do - but the trick is finding someone nearby. I'd be willing to part with a set for the price of shipping and a nice craft beer - but seeing as …

Hi folks. This is my first post to these forums. Just starting my first retro build. Want to put together a classic 1993 PC to stoke that nostalgia. Pretty excited, it's all I can think about since I decided to start. Already sourced a case and a motherboard. Isn't that case a beauty? Case Photo.jpg …
