Tending to retro hardware is a real balancing act. In an ideal world, you can use all the parts the device originally came with for all of eternity; however, PC parts are far more fickle than that. Over time, components will give out, and you’ll need to find something to replace them. The only problem is that the specific part you need has been out of production for decades, and the only surviving models people are willing to sell are getting older and pricier by the year.
