I have been heavily involved in the computer field as a hobby and in my work for over 40 years, since Sir Clive Sinclair managed to sell me a Sinclair ZX80 computer in late 1979. This computer had 1 kilobyte of memory and connected to the television. You could program it with its in built Basic Language and many a happy hour was spent keying in programs out of magazines and then spending even longer debugging the code that you had incorrectly entered. It was advertised as powerful enough to run a nuclear power station.

I progressed from this to a Compukit UK101 computer, which had a massive 8 kilobytes of memory, based on a home brew kit from the USA. It still connected to the TV and had glorious black and white graphics and no sound.

From there I was seduced by the Acorn's BBC Computer with 32 kilobytes of memory, full colour TV output, floppy disk drives and sound. This was a marvelous piece of kit for it's day.

I was then introduced to the Atari ST with a whopping 512 kilobytes of memory, which I increased to 1 megabyte, but still using floppy disks as the main storage device. It had better sound and graphics than the BBC and it could be attached to a colour monitor for better graphics and the game Starglider had to be seen to be believed!!.

Then came the Amstrad 80386 PC which had 4 Megabytes of memory, Dos 5 and Windows 3.0, colour VGA Monitor and a 65 Megabyte Hard Drive!! There was no way I would ever manage to fill that hard drive!!. Now we have 10 Terabyte Hard Drives available and many gigs of memory.

​

Since then I have used, built and repaired pc's and with Windows 10, everything is so easy now.
