My first computer was a TRS-80, Model I, Level II, starting out with all of 16K RAM and a cassette player for storage. I would follow the latest Radio Shack catalogs with wide eyes.
They started losing my interest when their first floppy drives only had 35 tracks, instead of a normal 40, and somehow still cost much more. At that, I think my aftermarket floppy drive and operating system ran around $500 anyway. But, you know, fast random-access storage! Maybe 160k of it! And you didn't have to keep fiddling with the volume control to get your programs to load!
It was spectacular, at the time. The expansion unit allowed a full 48K of RAM and room to install a serial port card, so I could add a 300-bps modem.
