When I was 11 I got my first computer as a Christmas present. It was 1982 and computers were completely different to what we have today.
My first computer was a ZX81, it was black and white (no colour) and it used a television for a screen. It had a touchpad keyboard that had to be pressed (typing was almost impossible. It was smaller than most modern laptops and it had … 1k of memory. This memory was RAM, which meant when the computer was turned off everything was lost. It could not be saved.
To help the reader understand how small this really was:
|Floppy Disk||1.44Mb||1,474,560 bytes|
|Gigabyte||1 Gb||711 Floppy Disks|
|Terabyte||1 Tb||754,297 Floppy Disks|
Most modern laptops come with at least a terabyte of hard drive memory and multiple gigabytes of RAM which makes my tiny 1k of RAM even smaller. As RAM it also meant that everything had to be programmed onto it using a language called BASIC. Everyone who programmed in BASIC knew the following program and the result shown in the screen on the right.
10 REM This is funny
20 PRINT “I love my teddy bear”
30 GOTO 20
This was very simple and most programs were a bit more complicated than this (especially when we understand the REM line doesn’t add anything to the program).
I remember spending an hour typing in a program that was actually a game of a bird chasing a butterfly. It has been a long time, but I think the butterfly was an M on top of a W that moved around and the bird was an M that changed to W to show its wings flapping.
One mistake and the whole thing did not work anyway.
Compared to modern computers it had almost no power, but at the time it was groundbreaking because it delivered affordable computing in the home. Soon after I got it it became obsolete when Sinclair introduced their groundbreaking Spectrum, one of the best selling computers of the early 80s with a massive 16k (expandable to 48k) of memory, colour interface and rubberised keys similar to those found on a calculator.
The Sinclair Spectrum had two more upgrades. The final version, the Spectrum+3 had 128k memory, a full sized keyboard and included an integrated floppy disk drive. This was the last computer I had before I got my first PC.

In both British and American English the spelling of program is the same when discussing a computer program.
In British English only the alternative spelling of programme is used to describe a plan, televison schedule or itinerary. In American English the spelling of program remains unchanged.
