Ah, some of you kids were sure spoiled rotten. I've had an Altair (and a PIP-8) back in 1976. The Altair had 512 bytes (not megs, not k, just bytes) of memory. It clocked at 700kHz (0.7 MHz) and could execute about 150,000 instructions/second. It had no OS at all, couldn't even run CP/M. You had to enter a program using toggle switches, one bit at a tine. 30 bytes of code was enough to get it to read the rest of the program from punched paper tape. I remember how excited I was when I got a 1k memory board. With 1.5k, I had just enough memory to run Tom Pitman's "Tiny BASIC". The teletype that I used to punch the paper tape and make printouts ran at 75 baud, and could print a complete page of text in about 12 minutes, upper case only. My current machine has 3 million times more memory than Altair, a processor about 10,000 times faster, and several hundred gigs of hard disk. And a printer that can do a 300 page book in 12 minutes, with typeset quality. I had a TRS-80, back in 1977. Originally came with 4k of RAM, and a 4K BASIC in ROM. That machine was incredible, press the power button, and it was ready to run. No hard disk, it read programs from cassette tape at 250 baud. I used to build computers for people who bought them as kits, then got in too deep trying to build them. Including a Sol-20 and several Altairs.
