Episode 152 - LIVE at VCF - Reviving Retro Panel

Lunar Lander is one of the best loves video games of all time. The game was created in 1969 as an homage to the recent Apollo 11. From there it would only spread. Just about anything that can print text has it's own version of Lunar Lander. The early history of this game is mixed up with something weird: two nearly identical programming languages. Today we will be using the history of Lunar Lander as a good excuse to look at an obscure tongue called FOCAL. This language is so close to BASIC that direct line-by-line translation is possible. But are the two connected?

In 1982 Intel released the iAPX 286. It's was the first heir to the smash-hit 8086. But the 286 was developed before the IBM PC put an Intel chip on every desk. It's design isn't influence by the PC. Rather, it reaches further into the past. Today we are looking at the strange melding of old technology, new ideas, and compatibility that lead to the 286.

In 1973 the world caught it's first glimpse of INTERCAL. It's a wild and wacky language, somewhere between comedy and cutting satire. But the compiler was never circulated. There would be later implementations, but that original compiler remained lost to time. That is, until now. This episode covers how the original source code was found, and my attempt to get it up and running.

The S1 operating system can do it all! It can run on any computer, read any disk, and execute any software. It can be UNIX compatible, DOS compatible, and so, so much more! But... can S1 ship? Today we are talking about an operating system that sounds too good to be true. Is it another example of vaporware? Or is S1 really the world's most sophisticated operating system?  

How do you make a computer act less like a computer? It sounds like some kind of riddle, but in the early 1960s it was an actual problem. As IBM customers transitioned from tabulators to computers they ran into all sorts of practical issues. Programmers became a hot commodity. But how do you find a programmer in 1959? And how can you even afford such a luxury? Wouldn't it be better if you could just use your new computer as a tabulator? Well, with RPG, all that and more was possible.

In the early 1960s a neat little machine came out of MIT. Well, kind of MIT. The machine was called LINC. It was small, flexible, and designed to live in laboratories. Some have called it the first personal computer. But, is that true? Does it have some secret that will unseat my beloved LGP-30? And how does DEC fit into the picture?

The LGP-30 is one of my favorite computers. It's small, scrappy, strange, and wonderous. Among its many wonders are two obscure languages: ACT-I and ACT-III. In this episode we are exploring the ACTS, how the LGP-30 was programmed in practice, and why I've been losing sleep for the last few weeks.

When I was down at VCF SoCal I ran into a strange machine: the Keypact Micro-VIP. It's a terminal without a keyboard, covered in dials, with a speaker and a switch labeled "voice". This chance encounter with the unknown sent me down a wild path. It involved the creeping spread of computing, chicken feed, door to door life insurance salesmen, and at least one early hacker.

A special treat from VCF SoCal. While visiting I had the chance to host a panel on restoration and preservation. I was joined by: David from Usagi Electric (https://www.youtube.com/@UsagiElectric) Rob from Souther Amis (https://www.southernamis.com/) Jim, Former Executive Director Computer Museum of America (https://computerhalloffame.org/home/about/)

Have you ever looked at an old computer and seen a weird typewriter thing tacked on? In most cases that's a device called a Flexowriter. It's half electric typewriter, half teleprinter, half tape reader, and all business! This episode we are chronicling the rise, fall, and weird business dealings of the Flexowriter.
