David L. Farquhar on technology old and new, computer security, and more
I was fixing a PC with a fairly late 486DX2-66 motherboard in it. In checking it out, I found an interesting setting in its BIOS: I can use its L2 cache as either writeback or writethrough. But what’s the difference? What are the pros and cons of writeback vs writethrough cache?
Writeback is faster but was harder to implement than writethrough, so not all systems support it. If it’s available and your software doesn’t malfunction, use write-back.
Computer Shopper was a monthly computer magazine, but it was more than that in some regards. Like the name suggests, it changed the way a certain demographic but computer. As hard as may seem to believe today, the main reason people bought it was for the advertising. The articles were good, but nobody bought it for the articles.
The Lionel 6457 caboose is a common and nearly iconic postwar Lionel car. It, or one of its close relatives, is probably the caboose you remember if you are into postwar-era Lionel.
The Allsop metal art large display stand #33306 is a useful ergonomic accessory for modern computers, especially laptops. But it also makes an excellent monitor riser or platform for using and displaying vintage and retro computers. Here’s a review with some tips.
I spotted a useful cable at a used computer store recently. I wasn’t 100% certain what it was, but I had the ability to rewire it into what I needed if it turned out I was wrong. Here’s how I went about identifying the cable with my multimeter.
They don’t make light bulbs like they used to. Well, at least they don’t make miniature light bulbs that work every time anymore, assuming they ever did. Here’s what to do when your brand new Lionel bulbs won’t light.
CRT monitors are getting expensive. CGA and EGA monitors even more so. In theory, every 1980s computer that used those types of monitor had one at some point. But the survival rate of the monitors was much lower than the survival rate of the computers, so there aren’t enough of them to go around. That’s led to a need to convert CGA or EGA to VGA.
Sometimes GPU fan screws go missing, and sometimes the only way to get a bargain on a used GPU is to buy one with a missing fan. There is a pretty good chance that you won’t have any suitable GPU fan screws in your parts stash. In my case, the smallest screws I had in my parts stash were M2 screws, commonly used on laptop hard drives and SSDs. But they were too big for the shroud on a GTX 1050 TI that needed a replacement fan.
In model railroading, a craftsman kit is a model kit consisting of wood and sometimes paper, and detail parts cast from soft metal. There is usually a fair amount of measuring, cutting, and gluing involved to build the model, and it usually requires a fair bit of patience and skill. That’s where the name craftsman kit comes from. You could get kids to build structures and even model railroad rolling stock.
Craftsman kits lost some prominence due to the widespread use of plastics, but they are starting to see something of a resurgence in modern times. Here’s why.
The prevailing wisdom regarding hard drives and early PCs is to keep your C drive small, ideally no bigger than 128 MB, and maybe even as little as 32. Otherwise, disk activity becomes unbearably slow. But what if I told you there is another way to fix slow hard drive access on early PCs?
