On a computer that cost him $12k in 1977 dollars (~$66k in 2026 dollars) for "14 lines of 64 characters on a monochrome monitor the size of a small black and white TV", according to the article that footnote 62 refers to (https://www.theverge.com/2017/9/9/16279582/jerry-pournelle-s...). Computers were hilariously expensive back then. Pournelle had a lot of money to burn and got real good at getting free stuff due to his Byte column.

An Apple ][ with 4k of RAM was $1200 in 1977 (~$7k now) (plus monitor, drive, and printer, also maybe a bit more than double the computer's price for a 48k machine). Not as expensive as whatever Pournelle bought but still a pretty major purchase.

A new typewriter in 1977, meanwhile, would run you about $50-170. About $300-950 in 2026 bucks. Less for a used one from the local pawn shop or typewriter repair shop or whatevs.

William Gibson, meanwhile, was a broke-ass teacher with a collection of punk records when he wrote Neuromancer, around 1982-1983. It's really no surprise he used a typewriter.
