I hate squashed screenshots. Does everyone forget that screens used to be 4:3? Does nobody notice the squashed oval shapes of planets (and other circles)?
Definitely fun days, working out how to be a bit faster than the BIOS and not use a single bit of DOS.
I'm of the opinion that writers should make it a habit in pieces like these to always include prices that have been adjusted for inflation. In this case, $2,000 corresponds to $6,731.61, which provides better context for the story.
Alley Cat had a very neat trick on the PC: it implemented its own clock independent of the CPU cycles. At the time, many games relied on counting CPU cycles to tell the time. This caused a problem when the next generation of PCs came out with a faster CPU (XT with 286 if I recall), because now the cycles went by much faster, making the games run insanely fast so it was impossible to play (fun sidequest: the Turbo button was supposed to help in this sort of situation). Alley Cat had no such issue since it implemented its own clock, and it can still run today at normal speed just as it did over 40 years ago.
I’m currently busy disassembling PC-MAN and trying to cram it into 16kB so it could be run on an original PC loaded from cassette. The game was distributed as a DOS booter and boo floppies required 32k, but PC-MAN is about 17k in size.
Alley Cat has a timing issue with the “kiss” noise used at the end of the Felicia screen and the “conflict” noise when you run into the dog.
Upgrading with a hard disk, a second floppy drive, or upgrading the graphics card was common.
Back then, you had 1 phone which cost around $50 a month in inflation adjusted dollars.
In California, there certainly was. The US economy had already started its decline, but from such a high that well-to-do Americans hadn't noticed. By contrast, because Europe had had to be rebuilt after WWII, the general populace had benefitted far less from the postwar boom.
In 1982, my family had a relatively comfortable middle class existence, but buying a home computer that cost (at the time) about half as much as a one-bedroom apartment would have been absolutely unimaginable to my parents. The ZX81 they bought for me cost £99.
