I started with a Super Board computer... and then TRS-80, and then Apple II. In those days, the 6502 machine code only has 1 accumulator and 2 registers. Hm... the computer has 48k RAM. If you have money, you can buy a 16k RAM card, and a floppy disk drive for 143k per disc. I can't remember how much the 16k RAM card cost, but it was a luxury. The floppy disk drive was about US$200. But it was very expensive considering it was $200 back in 1983.
