I recently replaced most of the fans in my dual socket rig. 20210122_172051.jpg 20210122_174724.jpg 20210122_185652.jpg Next on my list will be either completely replacing the power supply or just replacing its fans. I have been a Lian-Li fan since about 2006 and held on to my original PC-65 case …

I made an estate sale purchase over the weekend of a P2B-DS fitted with dual P3-800's. Imagine my surprise after it posted up with no issues. After a night of wondering which case I should put it in, I settled on my old Lian-Li PC-65. It is still a work in progress as I need to install drives, fan …

Thank you all so very much for the advice and the motivation to get my hands dirty with these again. I have placed #2 in mid-size AT case, posted it up, and prepped it for when I track down a working cd-rom, floppy disk drives, and sound card. I suppose I buried the lead when I didn't mention my …

With the recent acquisition of my childhood 486, I want to cut back on some of my existing setups. I have two cases (one with clockspeed display and one without) and four boards. I could use everyone's advice. Which boards should I keep for the two cases? 1. 471G 486DX4 @ 120MHz 128K cache 16MB RAM …

I finally got around to two mini-projects. 1. 3D printing the SD-IDE bracket a user posted on this forum. It has some issues with the rear screw holes not lining up, but I think that is more on the PCBs not being consistent than the print. 20190716_072654.jpg 2. I originally purchased some plastic …

The computer came from the seller with a short non-flipped cable. I used that with the onboard FDC thinking it came stock with the system. On the IBM FDC card, I followed minuszerodegree's guide to set it for 1 floppy disk only (terminated and jumpered to 2).

So I have my Vendex Turbo-888-XT with battery corrosion all cleaned up and traces good (that I am aware of). However I ran into an issue where the floppy drive head will not move when the system tries to read a disk. The light turns on, diskette spins, but no head movement and only a disk bad error …

Do I have to replace the dallas battery or is there any easier way out? If the motherboard does not have jumpers/pins for an external battery, it will need fixing or replacing. There is a simple fix if you have access to a dremel and soldering iron. A quick google of the number on the chip will …

It's output does not look very sharp on the CRT and it goes dim sometimes when the XT attempts to seek the floppy disk. Replace/fix the power supply! The voltages are probably way off, especially, when on load of floppy drive... I will carefully open it and see what I am working with. What are your …
