The first computer with a keyboard and screen and such that I owned was a Macintosh 512k with an 800k floppy drive - I also bought a 15" dot matrix printer and the whole lot cost around $4000 - in 1985 dollars. I had been using IBM PCs at work for a couple of years and also x86-based Concurrent CP/M machines (with an 8" floppy disk and 10Mbyte hard disk.)

The first "computer" I owned was a SC/MP microprocessor system with 256 bytes of memory, programmed by 8 switches on the front and output was 8 leds.

Since then I've been through 4 laptops, 3 desktops and numerous work computers.
