The first computer I ever worked with was a DEC PDP-11/70 running RSX-11M as the OS. The photos will give you some idea what it looked like. To boot it you set the boot address using the switches on the front of the CPU, then turned the power on. It's hard drive was a 14" cartridge hard disk permanently mounted inside the racks. it had two additional removable 14" cartridge hard disks for data storage, further storage and backup was mag tape.
My first PC was an XT compatible, with an 8088 4.77MHz processor, 640k RAM, two 360k 5 1/4" floppy drives and an amber monochrome monitor. The OS was MS-DOS 3.1. I later upgraded this to a CGA video card and monitor. And added a 10 Meg hardcard and 300 baud modem. Its last OS was MS-DOS 6.22. I used that computer for 16 years. It finally died, the keyboard interface chip and finally the hardcard.
