There are various YT videos already of Altair playing Daisy... But:
I was reading (online) through some old magazines from early 1970s, and it had a "write in" section from readers. I came across a write-in from a certain Kurt Inman. The write-in (from Kurt) mentioned how he was 11 years old and had written a variety of programs and was about to put together an Altair. Cute story, hoped Kurt went on to do great things...
(page 7, November 1975)
After some more browsing, I found an article about a year later from someone with this same name (Kurt Inman) of a simple program for an Altair. I can't say for sure if it's the same person, but I'd like to imagine this now 12-year old had submitted a full article to a magazine.
(page 31)
Since I've never actually used an Altair before, I figured this would be a good excuse to try it out. I've written plenty of "guess my number" games in BASIC, but never in raw machine code.
Is there an Altair simulator that will emulate playing audio on a radio?
Simulator:
Here is the code transcribed from the article, if anyone else wants to give it a go. And attached is a BIN file that the simulator above seems to support loading.
Cheers Kurt, wherever you are :D
