David L. Farquhar on technology old and new, computer security, and more
If you’re looking for the best chip puller or IC extraction tool, I don’t think anyone will argue with my assertion it’s the Jonard EX-2. I finally picked one up this fall after watching various retro Youtubers use them for more than a year. The videos aren’t exaggerating. This chip puller makes life with retro machines much easier. This is my Jonard EX-2 review.
Can you stain pine wood to look like oak? You can, but it takes some patience and the right materials to get consistent results you’re likely to be happy with. Practice helps too. Here’s how to stain pine to look like oak.
This trick can be helpful if you want to attempt a DIY project like a picture ledge, but want it to match other furniture in the room. And it also applies to other finishes, not just oak.
On Thursday, November 12, 2020, I migrated to a new host. My old host was a bit too far behind on some of the major software required to run current WordPress builds correctly. I decided that building a new server and migrating my 20+ years of content to it was my best option.
It should be a lot faster. The new hardware is faster. The new software would be faster even if it were running on the same hardware. And I found and fixed a couple of problems along the way. But if you notice something not working, please post a comment to let me know.
And if you noticed the server was up and down a lot on November 12, that’s why. The new server didn’t work on the first try, and it takes about two minutes to change the firewall rule to point to a different server.
One question that comes up pretty frequently among vintage computer enthusiasts is what to use as a MOS 6522 replacement. Commodore used this chip extensively, but so did others. There are suitable replacements in the form of second-source 65c22 chips, but not all of them work. Here’s what to use.
Commodore went out of business in 1994, and started winding down its chip production as early as 1992. But some of its designs were available through second sources, and the 6522 was one of them.
My son was having trouble with the Realtek network card in his PC. The question was what to replace it with. Well, it wasn’t going to be another Realtek-based card. Should I get a Broadcom? Or an Intel? Let’s look at the pros and cons of a Broadcom vs Intel NIC.
In the 80s, when all-in one computers like the Amiga 500, Apple IIc, Atari 520 and 1040ST, and Tandy 1000EX and HX were popular, monitor stands helped us keep our systems organized. It’s hard to find a monitor stand from the period now, but there’s an acceptable modern substitute, or you can make your own. If you make your own, you can make it suitable for 8-bit systems as well, letting you stack your disk drives next to a monitor with the system unit underneath.
A photo of someone’s newly acquired Amiga 2000 turned up on a vintage computing forum recently. It was sporting two 3.5″ drives, but also had a Chinon 5.25″ drive in its lower bay. Someone asked what the 5.25-inch drive was for. I responded it’s a good sign the system has an Amiga Bridgeboard in it. The Bridgeboard turns a big-box Amiga like a 2000 into an odd hybrid Amiga-PC clone.
First released in 1987, the Amiga Bridgeboard consisted of most of an IBM PC clone on a single full-length card. It had its own ISA bus, but it was also able to access some Amiga functionality, not just to provide IO but also to provide ways to share data between the two systems.
One question I get a lot, as a former Amazon bookseller, is why some books are so cheap on Amazon. Namely, how can books sell for a penny? And why do they sell that cheap? I can tell you nobody wants to make a living selling books for a penny, but it is possible to do so and turn a profit, if a seller is careful and the market conditions are right. Here’s how they do it.
I have a combination home office/man cave that I work out of. It’s a basement room the previous owner never finished. I fixed some mistakes and adapted it to my own needs. One thing it always lacked was a ceiling. After weighing my options, I decided to use wood planks. Call it rustic. Call it cheapo. Or whatever else you want. Rustic planks are in now, and for a do-it-yourselfer, planks offer a compelling option.
Many vintage computers have RS-232 ports, and some current equipment does too, especially network switches. But what is RS-232? And why did it only partly fall out of favor? And what about RS-232C? I’ll try to clear up the confusion.
