My First computer was a TC-500 from Burroughs. I actually worked for Burroughs as a Field Engineer. The TC-500 was based on the L-2000. It only had a keyboard and a ball printer, driven by thin metal straps. The hard drive was 40K head-per-track (5) ceramic disc. The memory was 2K and the computer was loaded with paper tape, connected to the keyboard. The modem was a 1200 baud unit, that was the size of a shoe box and cost $2000.
