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
