Comment Re:It had USB? I recall they did not. (Score 1) 60

Yeah I saw the USB support there, but there were no physical ports. I'm assuming if I had socketed in a USB PCMCIA card it would have worked. Someone in the comments section noted to me that there were rapid-fire versions of this laptop about the same time, and the version that didn't have USB had a very short run.

Submission + - The 1997 Powerbook G3 - Apple's hope for redemption. (youtube.com)

Shayde writes: A friend of mine gave me a Powerbook G3 to play around with. Turns out this was one of the first machines able to run OSX, and was built during the transition period for Apple after Steve Jobs came back in to rescue the company from bankruptcy.

Submission + - Hand-wiring an RS232 hookup to get a 30 year old clamshell computer online (youtube.com)

Shayde writes: I really wanted to get this HP95LX talking to the internet at large, but network stacks for DOS in 1991 were pretty limited, and this machine didn't even have the hardware for a network connection. It did have a serial port though — a flat 4 pin custom interface.

I did a bunch of research and learned how to custom built an RS232 hookup for this port, and using an external Wifi module, got it online and talking to the retrocomputing BBS.

Submission + - Repairing a 45 year old handheld Mattel "video game" (youtube.com)

Shayde writes: I went to do a quick youtube short on playing the 1976 Mattel handheld game "Auto Race" but figured out pretty quickly that the game wasn't working. So I dove into disassembling the unit and figuring out the problem. Taking it apart and debugging it was fun. (Slight spoiler: I figured out what was wrong, was an easy fix), and the game plays great now!

Submission + - SPAM: Working with a 40 year old DEC vt220 terminal.

Shayde writes: I was fortunate enough to have someone reach out to me and ask if I wanted a couple old terminals he had lying around. He was hoping they'd go to a collector or someone who would appreciate them, not someone who would flip them on ebay or sell them for scrap.

I've always had a weakness for VT220's, as to me they were the first of the 'modern' DEC equipment line. They came out with the VAXes in the 80s as the powerhouses for education and small business. This video is me documenting picking up the terminals, getting one set up hooked to a Raspberry PI and putting it through the paces.

Submission + - Running CP/M and Turbo Pascal on a 40 year old Apple II Clone (youtube.com)

Shayde writes: In 1984, Apple II's were at the top of their game in the 8 bit market. A company in New Jersey decided to get in on the action and built an exact clone of the Apple. The Franklin Ace was chip and rom compatible with the Apple II, and that led to it's downfall. In this video we resurrect and old Franklin Ace and not only boot ProDOS, but also get the Z80 coprocessor up and running, and relive what coding in Turbo Pascal in the 80s was like.

Submission + - Restoring a 1986 DEC PDP/11 Minicomputer - Will it boot?? (youtube.com) 1

Shayde writes: I've been working on a PDP/11 I basically got as a 'barn find' from an estate sale a year ago. The project has absolutely had it's ups and downs, as the knowledgebase for these machines is aging quickly. I'm hoping to restore my own expertise with this build, but it's been challenging finding parts, technical details, and just plain information.

I leaned pretty heavily on the folks at the Vintage Computing Federation (vcfed.org), as well as connections I've made in the industry — and made some great progress.

The latest chapter in how it's going was just posted, check it out if you're keen on retrocomputing and old minicomputers and DEC gear.

Oh yes. Excellent news. Because nuclear power is the cleanest, most dependable, most regulated, and lowest impacting power source on the planet right now, lets shut it down for no realistic reason. "Spinal sublexations which cause ill health?" Ah, you're a chiropractor. Sooooo, your position is that mythical twisting of the vertebrae (Oh yes, sorry, chiropractors have co-opted the term 'subluxation' to mean whatever they think might be wrong, rather than an actual anatomical definition. Convenient) ... which you say causes ill health, is due to radioactivity, that no one has ever sensed? That's quite a reach my friend.

The short version is nuclear power is the safest power we have. (Xref: http://climatesight.org/2011/03/15/nuclear-power-in-context/ ) That chart shows direct-impact deaths, and does not show the number of mine workers who die yearly mining coal, or the oil rig operators who die, or the VAST environmental impact directly from burning fossil fuels. In 40 years of nuclear power, there have been THREE nuclear plant failures. TMI, Chernobyl, and fukujima. TMI resulted in negligible radiation release. Chernobyl resulted in 64 confirmed deaths (though there is ENORMOUS variation in forecasts for 'potential deaths'), and Fukujima has, we've noted so far, had ONE death. One.

I can already hear the raising of the "But, it's Radiation! Radiation is BAD!" - yes, of course it is, but it must be taken in context. The levels talked about around these plants varies wildly, and your random "because we have nuke plants, people are getting more colds because of mythical undefineable spinal shift" is a textbook "Correlation proves Causation - a logical fallacy.

Psst. Locomotive is between 55 tons and 200 tons. Say a high speed rail has 1 locomotive and 10 cars, the cars are relatively light. Call it 50 tons. So that's about 1100 tons. A 747 maxes out somewhere around 125 tons. I'd rather have 1100 tons on the ground moving at 250mph than 125 tons 30,000ft in the air at 550mph that can be aimed anywhere, any place, and dropped on anyone's head.
