Yellow Swans - anyone else obsessed with their music?

I guess I'd call it "harsh ambient?"

It's one of my favorite genres, and Yellow Swans are masters of it. Is anyone else here a fan?

Total beginner who just wants to figure out how to use the game I bought - please be kind!

I just got an R36T MAX, it's my first time with anything like this. I'm running into all sorts of confusion when I try to play games, and rather than asking a million questions, I just wonder if anyone knows of a good end-to-end tutorial.

For example, the controls seem to be all messed up in MAME, and I can't seem to get the settings to accept the buttons the device actually has.

I figured out the basics like how to add games, change some shader and aspect ratio settings, and get to the settings. But so much seems to be obscure, and searching for help in videos and forums leads me down rabbit holes that may or may not be relevant to my setup, and get into a lot of jargon that makes me think I have to learn more even to understand what they're saying.

All I wanted to do was play some fun games, I didn't want to turn this into a big deal. I know these are cheap devices and I shouldn't expect too much, but I would be so grateful if there was just a READ ME file that had everything a dummy like me needs to know.

CityEl electric microcar

A Danish EV for one person, designed for low-impact urban transportation. Originally launched as the Mini-El in 1987, renamed after objections from Austin Rover, makers of the Mini.

It has gone through iterations and improvements over the years, continuing to be produced in various forms until 2018, first in Denmark and later Germany. Enthusiasts and hobbyists still drive and collect them, often upgrading to the latest available battery technology.

Three body styles have been produced: a solid roof, a targa version with a removable center soft top and solid rear windows, and a fully open convertible. The entire top half of the vehicle hinges upwards on gas struts for entry.

The original in 1987 had a top speed of 25 mph (40 km/h) and a range of just 37 miles (60 km). By 2018, it had a top speed of 40 mph (65 km/h) and a range of 55 miles (90 km) thanks to lithium ion batteries and a 4 kW motor, making it practical for daily commutes.

The CityEl weighs about 500 pounds (230 kg) and has a cargo capacity of 10 cubic feet (280 liters).

If falling in love was an album, this is what it would sound like.

One of the most beautiful albums I've ever heard. It makes me feel like Billy Wilder is filming me on a rowboat in Central Park under a warm mid-day sun shower.

Just found something I posted on Usenet in 1997 - Morrissey on TFI Friday

I won the ticket from XFM calling in with the answer to the question "where would you find a buck-toothed girl?"

It really was a fun day. Sting happened to be standing next to me on the floor while we watched Morrissey perform. He was very buff!

Telepathic Instruments Orchid ORC-1

A new device, but with strong cassette futurism influence and style. It's a chord-focused synth, in the tradition of the Omnichord from 1981.

Telepathic Instruments was co-founded by Kevin Parker of Tame Impala. I'm not in the market for synths, so I can't really speak to how good this is or isn't, but I love to see the aesthetic.

They got Matt Berry and Jemaine Clements to do the promo video for it, and that alone is one of the best promos I've ever seen, so that's fun: https://youtu.be/hbO1z13WP8o?si=pckZ5y9bWJlig3CW

Regnecentralen Piccoline

A Danish computer from 1984 with a 16-bit Intel 80186 and 256KB of memory. It launched with Concurrent CP/M, a multi-tasking OS that was unusual for a microcomputer in that multiple users could share one machine. Unfortunately, lack of IBM PC compatibility doomed it in the marketplace, despite later updating to Concurrent DOS.

Prince 50-function onboard car computer

Prince Corporation in Holland, Michigan invented the trip computer in 1980. It could mount on the dash of your car and provide information including location, ETA, time of day, miles to your destination, MPG, miles left in the fuel tank, and cost per mile in real time.

Since GPS did not exist yet, it used your starting destination and speed for many of its calculations. It connected to the vehicle's fuel flow sensor and speedometer sensor for data.

I found this news report from the time: https://www.youtube.com/watch?v=8hEg6XP6t5Q
