For that matter, why is that light constantly blinking? Is that bad? In this blog post, I will explain what the two lights on an Ethernet port mean.

Pentium MMX retro gaming PC

Pentium MMX retro gaming PC

The Pentium MMX represents a sweet spot in retro computing. Prices aren’t too far out of hand yet, and with one system and a utility, you can slow it down to match speeds with various other vintage systems, including the 386 and 486 generation, for running speed-sensitive games. This means one system can run DOS games going back to approximately 1987 or 1988, and still do relatively well with DOS and Windows games up to approximately 1998.

It also means you can use relatively inexpensive and still-plentiful PCI cards. PCI-based 486s exist but they are uncommon and getting expensive. And 386 PCI motherboards don’t exist.

MFM vs IDE hard drives

IDE was the standard PC hard drive connection type for around a decade and a half. The only standard that outlasted it was SATA, which is a direct descendant. IDE was a much greater departure from the standard it replaced, which we commonly call MFM.

IDE was an acronym for Integrated Drive Electronics. The earlier standard, which we colloquially call MFM but would more properly call ST506, put most of the drive control logic on the host interface, which was whatever controller card you connected to the computer to interface it to the drive.

Insignia RCA to HDMI converter review

Best Buy sells two devices under its Insignia house brand to help you use HDMI equipment with older devices. One of them is intended to allow you to connect old game consoles, VCRs, video cameras, or other devices with RCA outputs to an HDMI TV. This is my Insignia RCA to HDMI Converter review.

Note that Best Buy has another device that does the opposite. When you are buying one in the store, be very careful that you are buying the device you intend to get. The RCA to HDMI converter has a model number ending in zero: NS-HZ330. There’s a device with a different model number that does the opposite.

Garage door goes back up? Try this

Garage door goes back up? Try this

It’s annoying when you push the button on your garage door opener to close it, and the door comes down a bit, seems to change its mind, and then the garage door goes back up on its own. There’s a workaround for this and there is also a fix. Fortunately this is usually something you can fix yourself.

Your garage door goes back up on its own because its sensors can’t see each other. Holding down the opener’s button usually overrides this, and for a permanent fix, make sure the sensors near the door are aligned and clear of debris.

In 1974, Marx introduced a steam freight train set, catalog number 2905, it called The Reliable that ran on a 6 volt lantern battery and sold through discount stores. If you have one today, it’s worth more than its original retail price, even adjusted for inflation.

The Marx Reliable was part of the Great American Railroads series. It had catalog number 2905 and was sold only in 1974 and 1975.
