My first "computer" was a Texas Instruments calculator that you could program in up to 50 steps.
Then I soldered and Mk14 together and programmed it in machine code. It took me 3 months to write a program that calculated my bio-rhythm. But running the program took barely half a second. I then regularly calculated my bio-rhythm for a while and found out that it offered no significant correlation with real life.
When the ZX81 arrived I was smoking 25 cigarettes a day and the Sinclair cost the same as smoking for 6 months. I promised myself (and my 6-year-old son) that I would stop smoking for at least 6 months to pay for the computer. The Z81 arrived and I haven't smoked since.
I expanded my 81 to 2K, put in a Forth rom (which I can't find anymore)
Then came the Spectrum and the QL.
I've never played many games and that's why the QL was the pinnacle for me and I still regret that my QL broke.
After Sinclair my main "computers" were from Psion.
Now I'm trying to get my ZX81 working again

There are four lights!
Step up to red alert. Sir, are you absolutely sure? It does mean changing the bulb
Looking forward to summer later in the year.

Bonjour Luc! I am always happy to ''see'' a new Sinclair/Timex friend. And by the way it took me more time to get the money to buy my first ZX81...I did not smoke. Any qestion about the ZX81 basic language, I am here! Have fun!
