Dinosaur sightings - old-school computer hardware

This is a picture of my old Sony SMC-70 computer, that was my first computer that I bought, in 1983 (came out in 1982) it had the first 3 1/2" floppy disks available commercially. It has a Z80A CPU at 4.072 MHz! it uses CP/M as an operating system, and the video mode can write on the screen at four layers. I also have a light pen and the printer that was available for it. You could also get a unit called a Supercharger with an 8086 CPU in it and the unit could be even more powerful.
