Long shots: Could you try to create partitions with LBA turned off? (Normal mode) if so, you could get full capacity with some drive overlay software. I have a 486 too that does support LBA. With one controller, even 8GB CF is working perfectly. On another controller it refuse with LBA turned on, …

Do I call this a steal or just a good buy? This guy I really to regularly about old stuff has sold me some parts earlier. He texts me, withn unknown motherboard and unknown CPU, and he finds himself too lazy to check what it is and if it works. No pics, no further info, but just €15 plus shipping …

Until about a year ago I had an Intel Seattle 440BX board. In an attempt to clean out a bit I sold it, in favour of an Asus board. Performance was about equal, but as said the bios did not let me play around with advanced settings. The Asus does, and send to be similar in build quality: good. No …

Native, foreign, as long as it has something special to it I'm happy :) For example, I'm quite happy with my Tulip PC Compact 2 (native). Because it is one of the faster 10MHz V20 computers around. My Philips P3105/3120 computers, also turbo XT with onboard almost everything including XTA. 768kB …

Just some thinking. 20ns cache should be able to keep up with 50MHz bus speed (absolutely no more than that), but the tag is doubtful. But what if your cache chips can't keep up with its rated speed, even with the extra wait states? A 40MHz bus only needs 25ns cache to keep up, so that's a bit of …

Aren't these V53c464; 64k x4? Any way: These chips should not be too hard to obtain, as these are fairly common. That would take your board up to the full 512kB. It would give you the same slow TVGA 8800 board but will do 800x600 at 256 colours. By looking at the board I guess it has been repaired …

Thankfully the memory soldered onboard also matches speed grade on the new ones: 70ns Faster can't do harm but slower mar result in instability or slow your card down (like the incompatible 41256 -80 ones you also have on your pucture)

I got into sound cards yesterday. The Sound blaster 32 didn't really fit well, all kinds of collision with cables and headers. Besides, the IDE cable for the CDROM would be exactly at the CPU cooler, blocking airflow. So I'll stick with a shorter card. I did test the card from my 386 computer which …

I had an issue where when you first turned on the 386 pc it did read floppies for about 15 minutes and after that it stopped reading the floppies and gave just errors, so if I wanted to transfer data from floppies to hard drive I had to do it immediately after I turned on the computer.

Maybe your best chance may be looking for one that already has been modified to fit a 2032 style battery. Or, if you're not afraid of soldering, change the old barrel yourself. Some have connectors for an external battery so you can just disconnect the barrel and plug in the external one.
