Do I read SICP or HtDP?

Black and white studio photo of a longhaired white cat sitting up on a small table draped with brocade fabric. The cat has a very large ruffly bow made of dark fabric attached to the right side of its collar.

Very fancy potato postcard from my collection, date unknown.

This picture shows the AlexTel terminal. It had a built-in phone for phone services and modem for Alex Videotex services. There are two graphics modes I've been able to find. As such, I've been able to display both NAPLPS images and Minitel images. Since this particular unit doesn't have a serial port (some do), I've used a phone line simulator to send it the graphic files. #vintagecomputer #retrocomputer

This picture shows an image of a screen that would have been part of a NAPLPS based service. You have navigation on screen as well as the content. It's nostalgic for me to watch how the image is built up with vector graphics.

This picture shows a vector line being randomly drawn on screen.

Bell Canada had a Videotex service from 1988-1994. The AlexTel terminal looked similar to the French Minitel terminal but had advanced NAPLPS vector based rendering. NAPLPS was the evolution of Telidon. It's too bad they weren't colour terminals but I've been able to display some NAPLPS samples.

Arduino is used to read the cards. Even though the idea of code in punch cards looks cool, it also looks like a huge hassle to organize. I appreciate that it's being revisited in a home experiment however.
