Very interesting. In 1978 I bought a system HP 2000 (running RTE III) for my Institute. It cost $175 000 and had a 15 mbyte hard drive the size of a washing machine, a reel to reel tape drive, a paper tape reader and 196 kbytes of memory. To do a 256 x 256 FFT -- masking -- and back TTF took most of a day. I can do the same (but 512 x 512) processing on this PC in the time it takes to press the return key. I do have to use the mouse to make the mask and that might take a minute or two. The *ist D has more processing power. The computer was housed in two 18" cabinets 6 feet high. Around that time I was running a Gretag 3140 printer. It had a computer with 16k of ram, no hard drive, and it had a row of switches (16, I think) on the front that hat to be set to either up or down for the machine to boot correctly. Input was either by TTY (four letter commands) or via paper tape. If the machine lost power, the program had to be reloaded via paper tape. We thought it was hot stuff at the time.....
