[quote]The ZX81 was a home computer produced by Sinclair Research and manufactured in Scotland by Timex Corporation. It was launched in the United Kingdom in March 1981 as the successor to Sinclair's ZX80 and was designed to be a low-cost introduction to home computing for the general public. It was hugely successful and more than 1.5 million units were sold before it was eventually discontinued. The ZX81 found commercial success in many other countries, notably the United States, where Timex manufactured and distributed it under licence. Timex later produced its own versions of the ZX81 for the US market

I remember the mighty Sinclairs, I started out with a rubber keyboard Spectrum 48K 8-) 8-) 8-)

you would put spectrum 48k, that will set off the commadore 64 fans sayin commadore had more memory when it didn't they had the same memory but used it differently.

My zx81 was home built and ran my first aircraft simulator,  my first sinclair project was back in 73, I'll deny my age.
