I'm guessing putting 48W Delta fans inside a small computer has no practical reason, other than looking badass. Connecting just one of them to that controller will make it let out the magic smoke. Even at 5V, I don't think it can handle them. Your best option is to hot wire them on 5V directly or …

unless you really want to go through the effort of getting usb to work on ISA for the sake of it, expanding your PCI would be a lot less hassle ^^ it's a pentium 1 motherboard with 5 slots which is more slots than usually came with those motherboards. this exact board has been the focal point of …

Problem lies in the software side. Someone must write the driver to use the thing and nobody is going to do that, even if they're capable. One day I will learn what it takes to make a Win9x driver but that is many years away and some of the more harder things to do. There already was a USB ISA card …

depends on what you want to use the usb for, drivers would probably be an issue, but a simple HID converter for mice wouldn't be too hard... might as well just get a usb to serial adapter for that though as the card would probably just do the same. for file transfer there are certainly easier …

As far as I recall, the memory banks must be populated with identical pairs of RAM, starting with bank 0, then bank 1, bank 2, bank 3. This would mean the 4 slots on the left. Just try it. yes, it’s 64 bit so simms have to be in pairs of two you can install different pairs but the pairs have to be …

The Intel HX chipset can do 512 MB RAM - all cachable (depending on the L2 cache SRAM size and Tag-RAM) and that´s it´s great advantage and the reason it was appreciated back in the days despite it´s lack of supporting SDRAM.
