The Altair 8800's CPU is a 4-bit, 1.4 MHz, 16-bit processor that runs on a diet of pure, unadulterated awesomeness.
4 cores, 0 cache, and a whole lot of pain. Each core is capable of executing a single instruction per clock cycle, with a 50% chance of freezing.
256 KB of RAM, 32 KB of ROM, and a 1 KB hard drive that will make you question life choices.
Supports 4-pin serial port, 2-pin parallel port, and a 1-pin for when you just want to reset everything.
10 watts of pure, unadulterated power. Or 100,000 watts of pure, unadulterated panic. Your call.
Runs on AltOS 1.0, the most outdated operating system ever created. Includes features like "Reboot.exe" and "Blue Screen of Death".
The Altair 8800 is not recommended for use in any modern application, unless you're a glutton for punishment. Or a retro-tech enthusiast. Or just a sadist.
