Marveling at Compute! Gazette, a magazine for the Commodore's 8-bit home computers.
It's very 80s. It's also really sincere and amazingly technical.
You could use the above music program if you special ordered a disk from the magazine. Or you could COPY THE ENTIRE PROGRAM BY HAND into your computer!!
Absolutely amazing. Also loving the directory of user groups. It's continually humbling to see coding as a historied practice, even if it's only from a few decades back.
